[0031] Specifically, the working box 10 is formed with a working cavity 11 for placing a component to be tested, the heat exchange box 20 is formed with a heat exchange cavity, the liquid inlet pipe 30 and the liquid outlet pipe 40 are respectively communicated between the heat exchange cavity and the working cavity 11, the heat exchange cavity is used for containing a heat exchange medium, the driving member 50 is adapted to drive the heat exchange medium to flow between the heat exchange cavity and the working cavity 11, and the heat exchange device 60 is adapted to adjust the temperature of the heat exchange medium in the heat exchange cavity.
[0032] The component to be tested can be a battery, a server, an electronic element or a data center, and the heat exchange device 60 can be a heat pump device, an electric heating device or other heat exchange devices 60.
[0033] During the working process of the test system, the component to be tested is placed in the working cavity 11, the heat exchange device 60 adjusts the heat exchange medium in the heat exchange cavity to a set temperature, the driving member 50 drives the heat exchange medium in the heat exchange cavity to enter the working cavity 11 through the liquid inlet pipe 30, the heat exchange medium flows through the working cavity 11 and then flows out to the heat exchange cavity through the liquid outlet pipe 40. The heat exchange medium exchanges heat with the components in the working cavity 11 and the component to be tested, so that the temperature in the working cavity 11 reaches the set temperature. After the heat exchange medium flows out from the liquid outlet pipe 40 to the heat exchange cavity, the heat exchange device 60 acts on the heat exchange medium in the heat exchange cavity, so that the heat exchange medium maintains the set temperature.
[0034] When the temperature in the working cavity 11 needs to be changed, the heat exchange device 60 changes the temperature of the heat exchange medium in the heat exchange cavity, the driving member 50 drives the heat exchange medium with changed temperature in the heat exchange cavity to enter the working cavity 11 from the liquid inlet pipe 30, the heat exchange medium flows through the working cavity 11 and then flows out to the heat exchange cavity through the liquid outlet pipe 40.
