[0002] A scroll compressor is a positive displacement compressor whose compression element consists of an orbiting scroll and a stationary scroll. Its operating principle is to utilize the relative orbital motion of the orbiting and stationary scrolls to create a continuous change in the enclosed volume, thereby compressing the gas. It is primarily used in applications such as air conditioning, refrigeration, general gas compression, and automotive engine superchargers and vacuum pumps. It can largely replace traditional medium and small reciprocating compressors. Scroll compressors typically use an IGBT as the primary heat source in their controller.

[0003] For example, the patent document with the announcement number CN219197638U discloses a shell heat dissipation structure of an electric scroll compressor, including a shell body, an annular opening boss, multiple cylindrical bosses, a square platform, multiple cylindrical platform studs, and multiple square platform studs. The shell body has an inner cavity bottom surface, an upper step surface, a lower step surface and an air inlet, and the square platform has multiple platform screw holes; the main heating element IGBT of the controller is installed on the square platform on the back of the shell, and its surface is close to the square platform. The low-temperature refrigerant gas and lubricating oil entering from the air inlet flow through the surface of the above structure, absorbing and taking away heat.

[0004] When the controller element IGBT in the existing electric scroll compressor generates heat, low-temperature refrigerant gas and lubricating oil are introduced from the air inlet to absorb and carry away the heat. This method of dissipating heat from the controller element IGBT cannot be circulated, resulting in poor heat dissipation efficiency. In addition, the existing controller element IGBT is all installed by bolts, which makes it inconvenient to disassemble and assemble, reducing the practicality of the device. Therefore, it is urgent to design an electric scroll compressor with a heat dissipation structure to solve the above problems. Utility Model Content

Through this design, the heat-prone part of the controller element IGBT111 is installed on the surface of the heat conducting plate 112, so that it can transfer the heat generated inside to the inside of the shell 113 through the heat conducting plate 112, and then introduce cooling water into the liquid inlet seat 211, so that it enters the circulating cooling pipe 212 for circulation, and is then discharged from the liquid outlet seat 213, which can absorb and take away the heat generated by the controller element IGBT111, and can circulate the heat.

[0024] Furthermore, the circulating cooling pipe 212 is arranged in a spiral shape inside the shell 113.
