Heat radiating module

散热模块

Abstract

本发明是为一种散热模块,设置于具有入风口的电子装置机壳内,散热模块包含有风扇、开关阀与控制器。风扇对应入风口。开关阀适于受到驱动而覆盖入风口的部分。控制器与开关阀电性连接,控制器是侦测风扇的转速,并且依据风扇的转速以控制开关阀覆盖入风口的程度。本发明藉由控制器来侦测风扇转速,并由控制器驱动开关阀来调整开口大小,减少外界灰尘被风扇经由入风口吸入散热模块内,以延长散热模块的使用寿命。
The present invention is a radiating module set inside of electronic device which has wind turbine. The radiating module includes a fan, a switch valve and a controller, wherein the fan corresponds to the wind turbine, the switch valve adapts to parts of wind turbine converted when driven. Controller electronically connected with switch valve is used to detect fan speed, and controls degree of wind turbine covered by switch valve according to rotate speed of fan. Controller detects fan rotate speed and drives switch valve to adjust opening size to reduce dust from external being drawn into radiating module through wind turbine so as to prolong service life of radiating module.
