When the temperature inside the controller casing is higher than the normal working range of the circuit board, the controller processing speed is easily reduced, the heat aging of the circuit board is accelerated, and the overheating of the circuit board is also prone to cause the circuit board to burn out, thereby reducing the safety and stability of the compressor in actual use.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0031] Please refer to Figures 1-4The utility model provides a technical scheme: a compressor controller shell structure, including compressor 1, the fixed seat 101 of integral fixation in the upper end of compressor 1, the controller shell 2 of setting in the upper of fixed seat 101, the base 201 of fixed in the lower end of controller shell 2, the top cover 202 of detachable installation in the upper end of controller shell 2 and the circuit board 3 of installation in the inside of controller shell 2, the fixed seat 101 upper end and the base 201 lower end between be provided with the heat insulation mechanism for reducing the heat conduction of compressor 1 to the controller shell 2 on.

[0032] Specifically, as shown in Figures 1-3 The heat insulation mechanism includes a heat insulation pad 7 installed on the upper end of the fixed seat 101, a heat insulation support sleeve 5 arranged between the four corners of the fixed seat 101 and the base 201, and a long rod screw 6 installed by screwing between the four corners of the fixed seat 101 and the base 201. Among them, the upper end of the fixed seat 101 and the lower end of the base 201 are provided with positioning slots 4 matched with the heat insulation support sleeve 5, which improves the structural stability of the heat insulation support sleeve 5 positioned between the fixed seat 101 and the base 201, and can reduce the problems of stress shaking, deviation and abnormal noise after installation.

[0033] In addition, the heat insulation support sleeve 5 is made of alumina ceramic material, which has high hardness, wear resistance, corrosion resistance, good insulation, high melting point, excellent chemical stability and excellent heat resistance, etc., which meets the use requirements of the heat insulation support sleeve 5 installed between the compressor 1 and the controller shell 2. The heat insulation pad 7 is made of polystyrene foam material, which has excellent heat insulation effect and can block and isolate the movement of the heat of the compressor 1 to the direction of the controller shell 2.

[0034] Specifically, as shown in Figures 1-3 The lower end of the base 201 is provided with a heat dissipation part for accelerating the heat conduction and dissipation of the base 201, which includes an inner groove 203 opened in the middle of the lower end of the base 201, a heat dissipation fin 9 installed on the inner side of the inner groove 203, a plurality of fins 901 fixed at equal intervals at the lower end of the heat dissipation fin 9, and a heat-conducting silicone grease 8 filled between the heat dissipation fin 9 and the inner groove 203. The heat absorbed by the base 201 can be efficiently conducted to the direction of the heat dissipation fin 9. The heat dissipation fin 9 is made of red copper material, which improves the heat absorption and heat dissipation effect of the heat dissipation fin 9.

[0035] Working principle: when using, the controller shell 2 needs to be installed on the compressor 1, the operator can pre-position the four heat insulation support sleeves 5 downward into the positioning slot 4 of the fixed seat 101, then take the controller shell 2, align the positioning slot 4 below the base 201 with the upper end of the heat insulation support sleeve 5 and insert it downward, then use tools to install and fix the long rod screw 6 between the base 201, the heat insulation support sleeve 5 and the fixed seat 101, at this time the controller shell 2 can support the bracket on the fixed seat 101, which can avoid the controller shell 2 directly adhering to the fixed seat 101, in the actual working process, the compressor 1 can generate heat when working, when the heat is conducted to the fixed seat 101, the heat insulation pad 7 can block most of the heat from continuing to conduct upward, since the heat insulation support sleeve 5 is also made of heat insulation material, so the heat is also difficult to conduct from the compressor 1 to the controller shell 2, at the same time, the heat-conducting silicone grease 8 and the heat sink 9 arranged below the base 201 can efficiently absorb the heat generated by the controller shell 2 and conduct it downward to the air, realizing the heat dissipation treatment of the controller shell 2, reducing the occurrence of the heat accumulation problem in the controller shell 2.
