A water-cooled spray heat dissipation permanent magnet speed controller structure

Abstract

This utility model discloses a water-cooled spray cooling permanent magnet speed controller structure, including a permanent magnet speed controller composed of a conductor rotor and a permanent magnet rotor coupled together. It also includes an upper housing, a lower housing, a voltage stabilizing component, a drain pipe, and a water inlet pipe. The upper and lower housings connect to form a cooling cavity. A voltage stabilizing component for balancing the air pressure within the cooling cavity is located on the top of the upper housing. The water-cooled spray mechanism includes a drain pipe and a water inlet pipe, both connected to the lower housing. Two sets of the water-cooled spray mechanism are provided, located on opposite sides of the cooling cavity, with the water inlet pipes in the two sets interconnected. Advantages: The upper and lower housings form a cooling cavity that encloses the permanent magnet speed controller, facilitating spray cooling and providing protection. The water inlet pipe introduces cooling water into the cooling cavity and directly sprays it onto different locations of the permanent magnet speed controller, carrying away heat and preventing high temperatures.
