Parent Product
Power Battery Test (Low Temperature Chiller)

EV Component Test Chiller (-20℃～+100℃ 1&6) operates within a temperature range of (-20℃～+100℃) and follows a systematic process flow. In this system, liquid refrigerant in the evaporator exchanges heat with circulating air inside the tank, transitioning from liquid to gas. The compressor then draws in the high-temperature and high-pressure refrigerant gas, which is subsequently passed through an oil separator to remove machine oil.

The compressed gas enters the condenser, exchanging heat with ambient air or cooling water, transforming into high-pressure normal temperature liquid. After passing through a filter, the refrigerant liquid is throttled and depressurized by an expansion valve, becoming a low-pressure liquid that enters the evaporator for cooling.

The unit utilizes a closed circulation system with an 80L pressure vessel, injecting antifreeze solution to prevent contact with outside air and ensure water condensation. The expansion tank, protected by nitrogen, broadens the heat transfer liquid's temperature range, preventing oxidation and extending its useful life.

The liquid refrigerant in the evaporator of the unit is exchanged with the circulating air in the interior of the tank. The temperature rises from liquid to gas and is drawn into the suction port of the compressor. The high-temperature and high-pressure refrigerant gas, after compression by the compressor, passes through the oil separator, which separates the refrigerating machine oil carried in the compression process.

It then enters the condenser, exchanging heat with ambient air or cooling water to transform from high-temperature and high-pressure gas to high-pressure normal temperature liquid. The high-pressure normal temperature refrigerant liquid is dried by a filter and then throttled and depressurized by an expansion valve, transitioning from a high-pressure liquid to a low-pressure liquid. The low-pressure liquid (lower boiling point) enters the evaporator of the unit, and the cooling air is brought to the inside of the tank through the circulating air to achieve refrigeration.

The antifreeze solution is injected into the 80L pressure vessel, and a fully closed circulation system is adopted. This prevents the antifreeze from coming into contact with outside air, ensuring water condensation. After the expansion tank is protected by nitrogen, the temperature range of the heat transfer liquid is broadened because its boiling point is increased. Additionally, oxidation of the thermally conductive liquid in contact with oxygen in the environment is avoided, extending the useful life of the thermally conductive liquid.
