1Liquid high and low temperature cycling test system

Liquid high and low temperature cycling test chamberCan meet the following two testing requirements, as detailed in the attached technical document.

Temperature fluctuation test (water-cooled assembly)

experimental medium:70%ethylene glycol+30%Water solution or50%ethylene glycol+50%aqueous solutionThe medium temperature is consistent with the ambient temperature,heating and cooling2.5~10℃/min,

The process is as follows:

1temperature from+0℃ rises to+85℃, maintain85℃ maintain15min

2temperature from+85℃ drops to0℃, conversion time is20min, maintain0℃ maintain15min

3Test cycle: number of cycles900time

3、Liquid high and low temperature cycling test chamberregulating system

project	explanation
adjustment method	Forced circulation flow, balanced temperature regulation method. The control system passes through the temperature point set by the systemPIDThe result of automatic calculation output is used to control the output of the heater, ultimately achieving a dynamic balance.
Medium circulation device	Adopting a closed-loop circulation system with a circulating water pump to force liquid flow.
Pressure cycle system	By controlling the secondary air pressure through an electrical proportional valve, the pressure of the medium in the circulation pipeline is pushed to change, so that the pressure change of the liquid meets the requirements of the pressure program change during the testing process The job requirements.

4Safety protection measures

project	explanation
1	Leakage protection for power supply;
2	Extreme high and low temperature protection; Temperature deviation alarm;
