Description

Self-priming heat dissipation blower suitable for high-humidity high-salt-fog environment Technical Field The utility model relates to a self-priming heat dissipation blower suitable for a high-humidity high-salt-fog environment, and belongs to the technical field of blowers. Background The conventional blower products are often applied to coastal high-humidity high-salt fog environments, and common heat dissipation modes of a high-speed blower motor include 1, a rotor with a heat dissipation impeller, 2, a motor with a heat dissipation fan, 3 and water cooling heat dissipation. When the heat dissipation mode is applied to a high-humidity high-salt-fog environment, the problems that (1) the end of the blower with the heat dissipation impeller is high in sealing cost and poor in effect at a high rotating speed, high-salt high-humidity gas easily enters the motor from the heat dissipation end, crystallization ponding is easily generated in the motor due to temperature change, and the service life of the motor is seriously influenced are solved. (2) When the high-speed motor adopts air cooling heat dissipation, the flow is required to be large, the pressure is low, and when the heat dissipation impeller is designed, the specific rotation speed of the impeller is overlarge due to the high rotation speed of the motor, the pneumatic efficiency of the heat dissipation impeller is low, and the heat dissipation power consumption is large.
