[0057] Working principle:

[0058] The drawer carrying platform 10 inside the cabinet 4 is used to carry the built-in device. By adjusting the positions of the front and rear two telescopic rods 2005 and the "L"-shaped clamping block 2006 in the clamping mechanism 20 inside the cabinet 4, the four corners of the built-in devices of different models are fixed and the built-in devices are clamped. The built-in devices can be powered by the power supply 11. The heat dissipation device 6 of the cabinet 4 and the built-in devices share a power switch 14 to avoid the situation where the built-in device is burned due to excessive temperature caused by forgetting to turn on the heat dissipation function. When the built-in device is working, the built-in device can be observed and controlled through the transparent observation window 1, the glove installation hole 2 and the gloves set on the cabinet door 3. The temperature sensor 16 measures the temperature in the cabinet in real time and displays it on the temperature display 17 outside the cabinet 4. When the actual temperature measured by the temperature sensor 16 is higher than the set temperature, the temperature control module 12 outputs a signal to start the heat dissipation device 6. When the temperature is higher than the set warning temperature, the alarm 18 can be used to warn in time. When the actual temperature measured by the temperature sensor 16 is lower than the set temperature, the temperature control module 12 outputs a signal to turn off the heat dissipation device 6. The replaceable desiccant bag in the desiccant box 13 can prevent the humid air from condensing or frosting on the surface of the radiator, and prevent the liquid produced after melting from causing rust or short circuit of electronic products in the built-in equipment.

[0059] In the first embodiment, the aluminum fin radiator 6102 absorbs the heat inside the cabinet 4, and the cooling medium in the pipeline transfers the heat from the inside of the cabinet 4 to the outside of the cabinet 4 through the circulating water pump 6105, the aluminum fin radiator 6102, and the water-cooled radiator 6201.

[0060] In the second embodiment, the aluminum fin heat sink 6102 absorbs the heat inside the cabinet 4 and transfers the heat to the cold end of the semiconductor refrigeration plate 6103. When the semiconductor refrigeration plate 6103 is powered on, it transfers the heat from the cold end to the hot end. The hot end is connected to a water cooling head 6104, and the heat is transferred to the cooling medium in the pipeline through the water cooling head 6104. The cooling medium in the pipeline transfers the heat from the inside of the cabinet 4 to the outside of the cabinet 4 through the circulating water pump 6105, the water cooling head 6104, and the water-cooled radiator 6201.

[0061] In Example 3, the aluminum fin heat sink 6102 absorbs the heat inside the cabinet 4 and transfers the heat to the cold end of the semiconductor refrigeration chip 6103. When the semiconductor refrigeration chip 6103 is powered on, it transfers the heat from the cold end to the hot end. The hot end is connected to the outside of the cabinet 4 with a water-cooled radiator 6201, and the heat is transferred from the inside of the cabinet 4 to the outside of the cabinet 4 through the semiconductor refrigeration chip 6103.

[0062] In Example 4, compressed air enters the vortex tube generator 6203 through the compressed air source pipe 6204. The cold air generated by the vortex tube generator 6203 when working is heat exchanged through the surface of the aluminum fin radiator 6102, and is exhausted by pressure through the cold air outlet pipe 6207 and the cold air outlet one-way valve 6206 arranged under the aluminum fin radiator 6102. After the exhaust pressure is released, the air outlet is automatically closed by the spring / elastic deformation action, and the compressed air solenoid valve 6205 opens or cuts off the air supply according to the output signal of the temperature control module 12.

[0063] In Example 5, compressed air enters the vortex tube generator 6203 through the compressed air source pipe 6204. The cold air generated by the vortex tube generator 6203 when working is directly passed into the sealed cabinet body 4 for heat exchange. The gas after heat exchange is exhausted by pressure through the cold air outlet pipe 6207 and the cold air outlet one-way valve 6206 arranged on the side of the cabinet body 4. After the exhaust pressure is released, the air outlet is automatically closed by the spring / elastic deformation action, and the compressed air solenoid valve 6205 opens or cuts off the air supply according to the output signal of the temperature control module 12.

[0064] The foregoing description of specific exemplary embodiments of the present invention is for the purpose of illustration and demonstration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the present invention and various different selections and changes.
