Specially developed for new energy vehicle battery packs

Suitable for hot and cold shock at various temperatures

It can provide antifreeze system for high-temperature and low-temperature tests for automobile battery packs, and can also be used as a refrigeration and heating system for hot and cold shock.

The double-layer high and low temperature chamber is used as a high and low temperature testing device for power battery samples. It is currently mainly used in the new energy battery industry. It can directly complete high and low temperature charge and discharge for battery cells, modules, and PACKs in the test chamber, or store high and low temperatures. Functions such as explosion-proof pressure relief and fire protection devices are added under the conditions when the battery fails to be tested.

Upper and lower double-layer box design

Antifreeze battery cooling system included

The two-box system operates completely independently

working principle

The variable frequency pump can adjust the circulating hydraulic pressure and flow rate to achieve high-precision control of the total range from 5% to 100%.

（The output pressure and flow rate of the circulating fluid can be set on the operation panel. Even under various customer piping conditions, without bypass piping adjustment, the set output pressure can be automatically controlled by the variable frequency pump. This can reduce the power consumption of the pump.）

The refrigeration unit mainly includes refrigeration compressor, condenser, oil separator, intermediate heat exchanger, internal circulation fan of the box, dry filter, condenser, evaporator, throttling mechanism, expansion tank, electrical control, etc.

The liquid refrigerant in the evaporator of the unit exchanges with the circulating air inside the box. The temperature rises and changes from liquid to gas. It is sucked into the suction port of the compressor. The high-temperature and high-pressure refrigerant gas compressed by the compressor first passes through The oil separator separates the refrigeration oil carried during the compression process, and then enters the condenser. After exchanging heat with ambient air or cooling water, it changes from high-temperature and high-pressure gas to high-pressure and normal-temperature liquid. The high-pressure and normal-temperature refrigerant liquid passes through the dry filter and then is throttled and decompressed by the expansion valve, that is, it changes from high-pressure liquid to low-pressure liquid. Low-pressure liquid (lower boiling point) enters the evaporator of the unit, and the cooling energy is brought to the inside of the box through circulating air to achieve refrigeration.
