Battery-specific temperature cycle test chamber Chiller tips

With the rapid development of the economy, the new energy automobile industry has also achieved rapid development, and the requirements of the battery industry are also getting higher and higher. In order to adapt to related industries, LNEYA has developed and produced the battery-specific temperature cycle test chamber Chiller, which has won the favor of large domestic and foreign companies. Therefore, today Xiaobian made a description of the use of the battery-specific temperature cycle test chamber Chiller.

The pressure ratio of the Chiller cycle of the battery-specific temperature cycle test chamber increases, the gas transmission coefficient of the compressor decreases, the actual suction volume decreases, the cooling capacity decreases, and the compressor power consumption increases, and the refrigeration coefficient decreases. When the actual resistance loss of the system is less than the nameplate head of the circulating water pump, the flow rate of the pump working point is greater than, and the head is less than the pump nameplate parameter. If other conservative factors of the design are added, the intersection of the pump characteristic curve and the system characteristic curve will always be biased to the lower right direction. Therefore, the flow rate will be greater than the larger the pressure ratio, and the greater the influence.

The external temperature of the thermal expansion valve (including the electronic expansion valve) Under normal conditions, the lower half of the expansion valve body is very cool, and there is dew, the refrigerant flow is very dull. Under abnormal conditions, first, the valve body is relatively cold, the surface has more dew, and even frost, the refrigerant has a loud sound (gas flow). The reason is that the filter is blocked, or the refrigerant in the power box leaks, and the valve hole is closed. The temperature of the Chiller capillary of the battery-specific temperature cycle test chamber is normal, the capillary is cool and dew is formed, and there is liquid flow sound. Under abnormal conditions, the surface is very cool and condensation, but the sound of the flow is louder, which is the flow of gas. The reason is that the refrigerant is insufficient. Second, the surface is not cool, condensation does not occur, and the flow sound is not heard. It is a filter blockage or capillary blockage. Battery temperature cycle test chamber Chiller evaporator temperature conditions Under normal conditions, the outer surface of the evaporator is very cold, the condensation water drops continuously, the temperature of the inlet and outlet air is large, usually Δt can be 12~14oC; abnormal situation The surface of the evaporator is not too cool, the dew is not much, or there is no condensation. It can be heard that the flow of the refrigerant is very loud, and the temperature difference between the inlet and outlet is small. The reason is that the refrigerant amount is insufficient, or the expansion valve opening degree is small.

Battery temperature cycle test chamber Chiller fully enclosed reciprocating piston compressor case temperature field can be divided into two parts, the upper case is affected by the suction of steam, the temperature is relatively low, in the slightly hot or slightly cool range, in the suction pipe There is the possibility of dew condensation on the surface of the local casing around it. The heat generated by the motor inside the casing and the frictional heat carried by the frozen oil are mainly carried out by the steam.

The effect of the case temperature is too high and the reason The surface temperature of the case exceeds the normal range, mainly because the intake temperature of the refrigeration system is too high. Excessive heat vapor enters the compressor and absorbs heat from the casing, causing the temperature of the steam to rise, thereby increasing the temperature of the casing. The temperature of the superheated vapor rises very high, and the temperature of the casing rises too high, which is unfavorable for the cooling of the oil, which affects the lubrication of the moving parts, accelerates the wear, and causes the bearing to hug the shaft. It also causes the exhaust gas temperature to rise.

Battery test cooling device Chiller common configuration instructions

Under normal use, the battery test cooling device Chiller needs to be discovered in time when any part of the abnormality occurs. This requires a clear understanding of the basic configuration of the battery test cooling device Chiller.

The battery test cooling device Chiller shell and tube condenser housing is normally the upper half is warmer and the lower half is warm. Under abnormal conditions, the entire housing is not too hot, and the original refrigerant amount is not enough. In another case, the entire housing is very hot due to insufficient cooling water or poor heat dissipation (scale in the water pipe). Under normal conditions, the casing condenser is very hot. The reason is that the cooling water is too small or the heat dissipation effect is poor. The other is that the outer surface of the casing is not too hot, because the refrigerant amount is insufficient.

Under normal circumstances, the battery test cooling device Chiller suction pipe feels cool and feels dew due to poor heat dissipation in the condenser, high condensation temperature or excessive refrigerant charge. Under normal conditions, the liquid tube is warm. Under abnormal conditions, the liquid tube is hot. The reason is that the condenser has poor heat dissipation, high condensation temperature or excessive refrigerant flow. Under normal conditions, the suction tube feels cool and feels dew. Under abnormal conditions, first, the suction pipe is cold and the dew is too much, so that the casing is exposed to a large area. The reason is that the refrigerant flow rate is too large, the liquid cannot be completely vaporized in the evaporator, and there is a liquid reflux phenomenon.

Battery test cooling device Chiller thermal expansion valve appearance temperature (including electronic expansion valve) Under normal circumstances, the lower half of the expansion valve body is very cool, and there is dew, the refrigerant flow is very dull. Under abnormal conditions, first, the valve body is relatively cold, the surface has more dew, and even frost, the refrigerant has a loud sound (gas flow). The reason is that the filter is blocked, or the refrigerant in the power box leaks, and the valve hole is closed. Under normal circumstances, the outer surface is very cold, and the condensation water drops continuously. The temperature of the inlet and outlet air is large, abnormal, the surface of the evaporator is not too cool, the dew is not much, or there is no condensation, and the refrigerant can be heard.

Description of the development of the wafer chip test system

With the development of the semiconductor industry, the wafer chip test machine has also made great progress. How much do you know about the development of the wafer chip test machine?

The integrated circuit industry has gradually emerged since the 1960s. Early companies were operating models. This model covers the entire chip production process of design, manufacturing, packaging and testing. Such enterprises generally have large scale, comprehensive technology and deep accumulation. Such as Intel, Samsung and so on. As the cost of technology upgrades increases and the requirements for the production efficiency of the IC industry increase, the entire industry is gradually moving toward a vertical division of labor.

This vertical division of labor greatly enhances the operational efficiency of the entire industry. Secondly, the design of relatively light assets and the separation of manufacturing and packaging of heavy assets are conducive to centralizing R&D investment in all aspects, accelerating technological development, and reducing the accuracy of enterprises. Entry threshold and operating costs; in addition, each link is handed over to different vendors to enhance the professionalism of the company and the accuracy of the production process. In addition, the separation of professional tests from the packaging and testing can reduce the repetitive capacity investment, and can provide professional testing services for small and medium-sized design manufacturers stably, reduce the testing cost of products and reduce the industrial cost by scale effect.

The IC test card is the key node of the industry chain, which runs through the whole process of design, manufacturing, packaging and application. From the perspective of the entire manufacturing process, integrated circuit testing includes design verification at the design stage, process inspection at the wafer fabrication stage, wafer testing before packaging, and finished product testing after packaging, throughout the design, manufacturing, packaging, and application. The process plays an important role in ensuring chip performance and improving the efficiency of the industrial chain.

Design verification, also known as laboratory testing or characterization testing, is to verify that the design is correct before the chip enters mass production and requires functional testing and physical verification. Process process inspection, that is, testing in the wafer manufacturing process, requires inspection of defects, film thickness, line width, critical dimensions, etc., and is a front test.

Wafer testing is performed by testing the completed wafers with the goal of picking out the bad dies before dicing to reduce the cost of packaging and chip testing, while counting the dies on the wafer. The pass rate, the exact position of the unqualified die, and the qualification rate of each type can directly reflect the wafer manufacturing yield and verify the wafer manufacturing capability.

After the chip is finished, the circuit will be damaged during the dicing, bonding, encapsulation and aging process of the integrated circuit. Therefore, after the package and aging, the circuit performance of the finished circuit should be tested according to the test specifications. Qualified finished products are graded according to the parameter specifications of the device performance, and the number of devices at various levels and the statistical distribution of various parameters are recorded. According to these data and information, the quality management department supervises the quality of the products and the production control unit controls the production of the circuits.

The development of wafer chip and wafer chip test system equipment, we must understand it, I hope that users can choose the regular manufacturer's wafer chip test system equipment when making purchases.

Motor test bench test and temperature system for vehicle components

All vehicle components must undergo rigorous testing, but safety programs must undergo more stringent durability and terminal testing. Many physical methods can be used to load the motor, but the small motor test bench is favored for its high speed, flexibility, and ability to reverse the test piece at high speeds.

The test bench is an AC power dynamometer with four-quadrant operation capability and can work independently in the speed or torque control mode. The system is equipped with a bench test system, a control system, a test and measurement system, a calibration system, and a cooling water thermostat system.
When the small motor test bench applies load and temperature cycling, many data parameters are recorded, some of which are recorded at high speed. Typical properties are motor voltage, current, temperature, torque and speed. One area of major interest is motor cogging (torque pulsation), especially at low speeds. Audible noise and vibration can also be a problem, and sensors and data acquisition can also be included.
                  

The high-voltage electric vehicle new energy motor test bench test area is used for the test of the test piece.
The motor under test can measure the current, voltage and power of the motor under test through a power analyzer.
The test area also includes the cooling system of the motor under test. It can detect the characteristic curve of the motor under test at different cooling temperatures. The cooling system has temperature and pressure alarm signals.

There are many reasons for motor testing. Durability testing ensures that the motor is calculated for the length of time to simulate the long-term life of the car. Performance testing requires benchmarking the performance of the motor at various temperatures and loads. Regardless of the type of test, various loads are applied when the motor is thermally cycled. Simpler motors typically withstand different loads, but remain at a relatively constant speed, changing only the input voltage to simulate high and low battery conditions.

LNEYA new energy battery motor test temperature control system KRY equipment is widely used in the industry, one can connect multiple test equipment at the same time, achieve precise temperature control, and do not interfere with the temperature control process.

Motor test bench environmental cabin option for new energy vehicles

Passenger car motor and commercial vehicle motor test bench can complete the stall torque and locked rotor current test, temperature rise test, continuous electric working characteristic test, motor maximum speed test, motor over speed test and feed operation characteristic test. At the same time, the test bench can feed the electricity generated during the test to the company's power grid through the frequency conversion system.

Motor labs and performance dynamometers must contain functions that control the stimulating elements of the application, the most difficult of which is usually temperature cycling. Many systems are designed to be propelled into the environmental chamber and, if necessary, shield any sensitive power tool test components from extreme temperatures or humidity.

The measurement and control system consists of a host computer monitoring system, a data acquisition system, a sensor measurement system, a frequency converter control system, a test bench auxiliary equipment control system, a safety monitoring system, and an early failure warning system. The measurement and control system uses a real-time bus as the main communication network and a CAN bus that communicates with the device under test. The upper computer monitoring system communicates with the data acquisition system and the inverter control system through real-time bus, dynamically controls the motor in real time, collects the data of each sensor at high speed, and analyzes and processes the data. The lower computer controller communicates with each auxiliary test system, and controls the auxiliary test system, and simultaneously collects the sensor data of each safety monitoring, such as: motor temperature, bearing temperature, coolant temperature, cooling pressure, etc.; The DI/DO interface controls, for example, the system issues an emergency stop command, and the lower controller immediately outputs the corresponding DO signal to cut off the power of the corresponding system to ensure system safety.

What causes sediment in the use of the chiller cooler?

A chiller is a water-cooled unit that uses water circulation to provide a constant temperature, constant flow and constant pressure cooling water. The LNEYA cold water system has its own working principle, that is, a certain amount of water is injected into the water tank of the machine, the cooling water is cooled by the refrigeration system, and then the cooling water is operated by the compressor. The cooling water is sent to the equipment to be cooled, the heat is taken away, then the temperature rises, and then flows back to the water tank to achieve a cooling effect. However, when using a chiller for a long time, there will usually be some dirt deposits in the chiller pipe or water tank. What is the reason below.

1.Chemical processor
If a zinc salt or a phosphate inhibitor is added to the water circulation system, zinc or phosphate scale is formed. Therefore, we must always carry out maintenance work on the chiller, not only to ensure the cooling capacity, but also to extend the service life of the chiller.

2. Process media leakage
The water cooler leaks, especially if it leaks oil or some organic matter causes deposits to form.

3. Air
Sediments, dust, microorganisms and their spores enter the circulatory system with the air, and sometimes insects are carried into the system, causing the heat exchanger to clog. When the environment surrounding the cooling tower is contaminated, corrosive gases such as hydrogen sulfide, chlorine dioxide and ammonia will react in the unit and indirectly cause deposition.
The LNEYA chiller cooler is a fully enclosed system that does not expose the media to outside air during use.

It can be seen from the above that in the use, the chiller needs to be maintained at all times, which not only ensures the cooling capacity, but also prolongs the service life of the chiller and the saving of circulating water.
