Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure fans, in particular to a heat dissipation mechanism of a high-pressure fan. Background Art

[0002] High-pressure fans, also known as high-pressure blowers or high-pressure suction and delivery fans, are widely used in various fields of industry, agriculture and infrastructure. They have the characteristics of dual blowing and suction functions, high pressure, maintenance-free and low noise. They are ideal choices for gas transportation, vacuum lifting and other systems. In order to ensure the normal operation of high-pressure fans, corresponding heat dissipation mechanisms are often provided to discharge the heat generated by the drive motor during its operation.

[0003] According to the patent CN209743244U, a heat dissipation mechanism for a high-pressure blower is disclosed. The heat dissipation mechanism includes a housing, the housing being provided on one end face of a pump cover of the high-pressure blower, with a gap between the housing and the pump cover; blades and a motor for driving the blades to rotate are provided in the housing, and both end faces of the housing are provided with through holes. The heat dissipation mechanism of a high-pressure blower of the present invention can help the high-pressure blower to perform auxiliary heat dissipation, ensuring that the high-pressure blower can operate normally for a long time. In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been solved. The problem of insufficient heat dissipation power of the high-pressure blower is solved by providing a through hole on the outside of the housing. However, in actual use, when the high-pressure blower is used for heat dissipation, a large amount of heat will accumulate on the surface of the motor housing during long-term operation, which cannot be dissipated in a timely and rapid manner. Simply increasing the air flow cannot meet the heat dissipation requirements of the motor operation when the external ambient temperature is high, which can easily lead to excessive heat accumulation and damage to the motor, affecting the normal operation of the high-pressure blower. Therefore, it is necessary to design a new technical solution. Utility Model Content
