The general operating principle of the temperature control unit 3 is as follows:
the air suction unit 2 blows air between the vest body 1 and the protective clothing into the temperature control unit 3. During refrigeration, the semiconductor wafer 312 is powered on, the cold surface is refrigerated, the first fins 311 are rapidly cooled, and the heat of the air flowing through the gaps of the first fins 311 is absorbed by the first fins 311; the heat of the hot surface is transferred to the heat transfer box 313 and is transmitted to the energy storage unit 5 through the heat conduction member 8.
During refrigeration, the effect of temperature reduction is realized through the refrigeration function of semiconductor wafer 312, and meanwhile, heat generated on the other surface of semiconductor wafer 312 in the refrigeration process of semiconductor wafer 312 is transferred to energy storage unit 5 through the heat transfer material, so that effective utilization of energy is realized and the performance of semiconductor wafer 312 is protected. And the energy generated by the heat on the hot surface of the semiconductor wafer 312 is stored by adopting an energy storage material with high specific heat capacity and a heat transfer material, so that the effect of prolonging the endurance time is achieved.
When heating, the PTC ceramic sheet 302 is energized to raise the temperature to a predetermined temperature, and the second fins 301 are rapidly raised in temperature, so that heat is diffused into the air in the vest body 1 to regulate the temperature in the vest body 1, and the specific principle is similar to that of the semiconductor sheet 312 for refrigeration.

the heat transfer box 313 is divided into a left heat transfer box 3131 and a right heat transfer box 3132, which are all metal boxes filled with heat transfer material, and an outlet and an inlet are formed on a side wall of the heat transfer box 313, which are connected to the energy storage unit 5 and take away heat from the hot surface of the semiconductor wafer 312.
The heat conducting members 8 are arranged in two groups, each of which comprises a first group of heat conducting members 80 and a second group of heat conducting members 81, which are both hollow pipes and are arranged in a sealing manner, and heat transfer materials are filled in the hollow pipes. The transfer material described herein needs to have a low thermal inertia to be able to rapidly transfer heat; in this embodiment, the transfer material is a liquid with low thermal inertia, and is selected by a person skilled in the art according to actual situations, which is not limited in the present invention.
The energy storage unit 5 mainly functions to store heat, and includes an energy storage heat insulation box 50, an electromagnetic valve 51 and a micro water pump 52, and the micro water pump 52 is disposed below the energy storage heat insulation box 50.

The energy storage material is mainly used for storing heat, so that the material needs to have relatively high specific heat capacity and needs to be used together with temperature reduction when in use. Before semiconductor wafer 312 starts to operate, or when the temperature of the hot side of semiconductor wafer 312 is too high, micro-water pump 52 is turned on, and the heat transfer material brings the heat of the hot side of semiconductor wafer 312 to the energy storage material for storage.
The first end of the first group of heat conducting members 80 is communicated with the left heat transferring box 3131, and the second end is communicated with the right heat transferring box 3132 after passing through the electromagnetic valve 51, the left part of the energy storage heat insulating box 50, the micro water pump 52, the right part of the energy storage heat insulating box 50 and the electromagnetic valve 51 in sequence. In this embodiment, a pair of inlets and outlets are respectively formed at two sides and a lower end of the energy storage heat insulation box 50, wherein the inlets and outlets at two sides are respectively connected with a micro electromagnetic valve, and one end of the electromagnetic valve is connected with the opening of the energy storage heat insulation box 50 through a hose.

The basic working principle of the heat transfer box 313 in heat transfer with the energy storage unit 5 is:
before use, a low-temperature energy storage liquid material, namely an energy storage material, is injected into the energy storage heat insulation box 50 through the water injection port 501. When the temperature of the hot surface of the semiconductor wafer 312 reaches a certain threshold value, the electromagnetic valve 51 is turned off, the valve is opened, and the micro-water pump 52 is opened to drive the heat transfer material to flow. The transfer material absorbs heat while flowing through the heat transfer cassette 313; as the transfer material flows through the energy storage material, heat is transferred into the energy storage material. When the semiconductor wafer 312 does not work, the micro-water pump 52 is closed, the electromagnetic valve 51 is electrified, and the valve is closed, so that heat exchange between the outside and the energy storage material is reduced, and the endurance time is prolonged.
