AI Technical Summary

Technical Problem

Permanent magnet generators are prone to heat accumulation during long-term use, resulting in magnet demagnetization and reduced efficiency. The prior art unidirectional exhaust method is not efficient.

Method used

A generator for a permanent magnet generator experimental platform including fan blades and transport tubes was designed. The fan blades were rotated through rotating rods and gears, forming an airflow circulation to accelerate heat dissipation, and at the same time, the cooling liquid in the transport tube spiraled forward to increase the cooling effect of the heat sink.

Benefits of technology

The combination of airflow circulation and liquid heat dissipation is achieved, the efficiency of heat discharge is improved, the accumulation of heat is avoided, the service life of the permanent magnet generator is extended, and the accuracy of the test data is ensured.
