Efficient heat dissipation type permanent magnet motor shell

Abstract

The invention discloses an efficient heat dissipation type permanent magnet motor shell, and relates to the technical field of motors. The efficient heat dissipation type permanent magnet motor shellcomprises a shell body and a fan. A front end cover and an inner end cover are fixedly connected to the two sides of the shell body respectively. A plurality of radiating fins are fixedly connected tothe peripheral side surface of the shell body in a fan shape. A heat dissipation box is fixedly connected to the top of the shell body. An air outlet pipe and an air inlet pipe are respectively fixedto the two ends of the heat dissipation box in a penetrating mode. Air collection pipes are respectively fixed to one end of the air outlet pipe and to one end of the air inlet pipe in a penetratingmode. A plurality of ventilation pipes are fixedly communicated with the inner sides of the air collection pipes. One end of each ventilation pipe is fixedly communicated with the shell body. The fanis fixedly installed in the heat dissipation box through a bracket. Hot airflow in the motor can be circularly fed into the heat dissipation box via a ventilation cavity through the air collection pipes, the heat dissipation box and the fan, the heat dissipation box cools the hot airflow, and the radiating fins can play a role in auxiliary heat dissipation.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a permanent magnet motor casing.
