Abstract

A centrifugal heat dissipation device and a motor using same are disclosed. The centrifugal heat dissipation device includes a main body having a shaft hole, a heat-absorption zone and a heat-transfer zone. The heat-transfer zone has a radially outer side connected to the heat-absorption zone and a radially inner side connected to the shaft hole. The shaft hole axially extends through the main body for receiving a shaft of a motor therein. A centrifugal force generated by the rotating shaft and accordingly, the heat dissipation device enables enhanced vapor-liquid circulation of a working fluid in the heat dissipation device, so that heat generated by the operating motor is absorbed by the centrifugal heat dissipation device and transferred to the shaft for guiding out of the motor, allowing the motor to have largely upgraded heat dissipation performance.

First claim

What is claimed is:

1. A motor with centrifugal heat dissipation device, comprising:
at least one shaft internally defining a hollow space and having a first end and an opposite second end; and the first and second ends being communicable with the hollow space;
a centrifugal heat dissipation device including a main body having a shaft hole, a heat-absorption zone, and a heat-transfer zone; the heat-transfer zone having a radially outer side connected to the heat-absorption zone…
