Controller heat dissipation structure of high-pressure cleaner

Abstract

The application discloses a high-pressure cleaner controller heat dissipation structure, which comprises a motor pump assembly, a connecting seat provided on the motor pump assembly, an air inlet formed in the connecting seat, a motor assembly arranged in the motor pump assembly, a fan arranged on the connecting seat and in transmission connection with the motor assembly, a motor fan cover installed on the connecting seat and internally formed with a fan cavity, a controller arranged on one side of the motor fan cover, the fan being capable of rotating in the fan cavity and guiding air flow, the fan cavity being tangentially provided with an air outlet, and the controller being arranged on one side of the air outlet. When the fan rotates, air is sucked from the air inlet, flows around the inner wall of the fan cavity and is discharged from the air outlet under the action of centrifugal force, and the air is cooled on the outer surface of the controller when being discharged.
