Cooling Heating Temperature Control System:

The test object is connected to a test platform adapter.
The components are cooled and heated by ethylene glycol aqueous solution.
Testing components need to undergo a specific temperature curve and record temperature changes.
Temperature variations usually range from - 40 to 100 degrees. (Extended to 150 degrees)
Tolerance tests are usually carried out in an infinite cycle.

Electronic Pump Cooling Heating Temperature Control System:

It can provide high temperature test and low temperature test antifreeze system for electronic pump, and can be used as refrigeration and heating system for cold and hot shock.
Cooling medium: ethylene glycol aqueous solution (- 45 degree antifreeze)

The process flow of Antifreeze Cooling Heating System is briefly introduced as follows:

The liquid refrigerant in the evaporator of the unit is exchanged with the circulating air inside the box, and the temperature rises. It changes from liquid to gaseous, and is inhaled by the suction port of the compressor. The high temperature and high pressure refrigerant gas compressed by the compressor passes through the oil separator first. The refrigerant oil carried during the compression process is separated and cleaned, and then it enters the condenser and passes through the ambient air or cooling water. Heat transfer, from high temperature and high pressure gas to high pressure and normal temperature liquid. The refrigerant liquid at high pressure and normal temperature is transformed from high pressure liquid to low pressure liquid through drying filter and throttling by expansion valve. Low pressure liquid (low boiling point) enters the evaporator of the unit, and the cooling capacity is brought to the inside of the box by circulating air to realize refrigeration.

Antifreeze liquid is injected into 80L pressure vessel and closed circulation system is adopted, which avoids the chance of contact between antifreeze liquid and outside air and ensures no water vapor condensation. When the expansion chamber is protected by nitrogen, the temperature range of the thermal conductive liquid will be widened, because its boiling point is raised. In addition, the oxidation caused by the contact between the thermal conductive liquid and oxygen in the environment is also avoided, thus prolonging the service life of the thermal conductive liquid.
