[0036] A filter plate 113 is fixedly connected to the right side wall of the heat dissipation cavity 106 , and the filter plate 113 can filter dust.

[0037] The front and rear end surfaces of the protective shell 101 are respectively fixedly connected with a mounting ear 102 , and the mounting ear 102 is provided with a mounting hole 103 that passes through the mounting ear 102 from top to bottom. The protective shell 101 can be installed and fixed through the mounting ear 102 through the mounting hole 103 .

[0038] The working principle and use process of the present invention:

[0039] When in use, the protective shell 101 is fixed on a plane through the mounting hole 103 on the mounting ear 102, and then the pipeline is connected to the return pipe 117 through the second connecting sleeve 118, and connected to the discharge pipe 119 through the first connecting sleeve 121. At this time, the medium circulates in the pipeline, and the heat conduction plate connected to the pipeline and the heat conduction mechanism such as the fan can achieve cooling or heating;

[0040] When in use, starting the compressor 114 can compress the medium to dissipate heat, or heat the medium, thereby completing the work of the heat pump. If it is started in a low-temperature environment, the compressor 114 is too low to work properly, and the heating plate 115 is used to start the compressor 114 to heat it, so that the compressor 114 can quickly reach a suitable working temperature. If it is started in a high-temperature environment, the compressor 114 is too high to work properly, and the semiconductor refrigeration plate 116 is used to start the compressor 114 to dissipate heat, so that the compressor 114 can quickly reach a suitable working temperature.

[0041] When in use, by starting the fan motor 109 to drive the fan shaft 111 and the fan blades 112 to rotate, the outside air can be drawn into the installation cavity 104, thereby performing heat dissipation on the compressor 114;

[0042] During use, if high or low temperature causes the medium to liquefy or vaporize, causing the pressure in the pipeline to increase or decrease, then under the elastic force of the spring 136, the pressure stabilizing plate 137 moves, thereby driving the sliding plate 139 to move, absorbing or discharging the medium in the pipeline, thereby maintaining the stability of the pipeline medium pressure. By starting the electromagnet 133, the magnetic plate 135 and the movable plate 134 can be pushed to move, thereby controlling the maintained pressure.
