[0002] At present, in the rotating environment test equipment, in order to achieve multi-axis rotation, it is generally carried out under the condition of not setting the temperature. For example, if the temperature control of high and low temperature is added, the two-axis rotation is used, and the chemical compound refrigerant is cyclically refrigerated. If leaked into the air, it will pollute the environment

Under the condition of three-axis rotation, the environmental test equipment needs to be improved in terms of temperature control, temperature control, and system reliability.

Mainly during the refrigeration process, the refrigerant should not leak. During the rotation of the equipment, the refrigeration system’s rotation connection interface is under insufficient pressure, and the seal of the interface is prone to leakage. The environmental test equipment’s refrigeration efficiency and temperature field temperature deviation in the test area during the rotation process , the technical indicators of temperature fluctuation and temperature uniformity do not meet the actual requirements

Now the general mechanical refrigerant refrigeration system adopts the circulation type, which directly increases the number of transfer pipes, especially after the refrigerant leaks, it will lead to very high maintenance costs and affect the service life of the refrigeration compressor

[0003] On the other hand, due to the complex mechanical structure of the existing three-axis turntable, it hinders the layout of the pipeline. The supporting rotating shaft has the function of conducting wires and cooling pipelines. Considering the weight of the rotating box of the environmental test equipment , the cooling evaporator must be installed in the box, which will virtually increase the weight of the rotating shaft support. This will increase the strength of the support frame to ensure safety and reliability, which will cause additional waste; the test box is easily disturbed in the rotating state, resulting in The three-axis turntable is still unable to achieve precise temperature control in terms of temperature control and the rate of temperature rise and fall. Considering the weight of the rotating box of the environmental test equipment, it is difficult to achieve it due to the limitation of the rotating support mechanism and the internal space size of the test box. Sufficient test area to meet the temperature test of large samples in a rotating state
