[0024] Example

[0025] Reference Figure 1-6 A heat dissipation device for a compressor includes a compressor 5 and a motor, the compressor 5 and the motor are connected via a coupling 1, and a first heat dissipation component is provided on the coupling 1. The first heat dissipation component is provided to avoid the problem that the compressor 5 and the motor are directly connected and it is difficult to dissipate heat from the connection. The first heat dissipation component includes a flange 2 and a fan sheet 3, one side of the flange 2 is fixedly connected to the coupling 1 by welding, and the other side of the flange 2 is connected to the fan sheet 3, and a through hole is provided on the fan sheet 3 at the same position as the flange 2, and the fan sheet 3 and the flange 2 are fixedly connected by a first bolt 4.

[0026] The compressor 5 is provided with a housing 6. In this embodiment, the housing 6 is no longer provided as a closed cavity. A front cover 7 and a rear cover 8 are provided on the housing 6. Both the front cover 7 and the rear cover 8 are provided with heat dissipation holes 9. A second heat dissipation assembly is provided on the outside of the rear cover 8. The second heat dissipation assembly includes a heat dissipation fan 10. The heat dissipation fan 10 is fixedly connected to the rear cover 8 by bolts. The heat dissipation fan 10 is an exhaust fan. External cold air enters the housing 6 through the heat dissipation holes 9 of the front cover 7. The exhaust fan extracts the hot air generated inside the compressor 5 to achieve air circulation. A rotating shaft 11 is provided in the housing 6. The rotating shaft 11 passes through the front cover 7. One end of the rotating shaft 11 is fixedly connected to the coupling 1, and the other end of the rotating shaft 11 is connected to the rear cover 8. The heat dissipation holes 9 are evenly distributed along the circumference of the rotating shaft 11. The fan sheet 3 is arranged opposite to the front cover 7, and a plurality of fan blades are arranged on the fan sheet 3.

[0027] Working principle: The motor is connected to the compressor 5 through the coupling 1, and the coupling 1 is provided with a fan sheet 3. When the motor rotates, it drives the coupling 1 to rotate, and the coupling 1 rotates and drives the fan sheet 3 to rotate at the same time. The fan sheet 3 is small in size and light in weight, and does not consume extra motor power while dissipating heat, thus avoiding the problem that the connection between the compressor 5 and the motor is directly connected and it is not easy to dissipate heat from the connection. At the same time, the fan sheet 3 is arranged opposite to the front cover 7 of the compressor 5. When the fan sheet 3 rotates, the external cold air is sent into the interior of the box 6 through the heat dissipation holes 9 on the front cover 7. The heat dissipation fan 10 is powered on, and the hot air generated in the box 6 when the compressor 5 is working is extracted through the heat dissipation holes 9 on the rear cover 8, thereby dissipating heat inside the compressor 5.

[0028] Therefore, the utility model adopts a heat dissipation device of a compressor with the above structure, which realizes air circulation in the box through the first heat dissipation component, the second heat dissipation component and the heat dissipation holes, discharges the internal heat generated by the compressor, and improves the service life.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
