Title:
HEAT DISSIPATION DEVICE AND SPEED GOVERNOR INCLUDING THE SAME
Document Type and Number:
WIPO Patent Application WO/2011/130944
Kind Code:
A1
Abstract:
A heat dissipation device (1), which is a multiple-sided prism composed of multiple heat dissipation units (101), has a corresponding polygon ventilation cross section. Heat dissipation layers for radiating heat from center to around are provided inside of the heat dissipation device. The multiple plates of the heat dissipation device are integrated into a common body, and three surfaces of the heat dissipation device are respectively provided with PCBs, so that the lengths of the PCBs are reduced to 1/3 of a conventional design and the heat of each PCB are no affected each another in the same space. The heat dissipation device solves the problems of the weight, space, radiating and cooling of a speed governor.
