【摘要】:提出了一種作用于功率器件的緊湊型液冷散熱器,特點為構(gòu)建了一個帶有旋槳式攪拌器的密封腔,能夠通過電機驅(qū)動葉片攪拌冷卻水形成流場以加強傳熱。為驗證該散熱器的效果,搭建了實驗平臺并設(shè)計了與模型外形尺寸相同的實心熱沉進行對比。通過調(diào)整熱源工作功率得到不同的溫度-時間曲線,當(dāng)熱源輸入功率為116 W、室溫為27℃時,相比于實心熱沉,使用緊湊型液冷散熱器的熱源溫度降低8.7℃。
[Abstract]:A compact liquid cooling radiator acting on power devices is proposed, which is characterized by the construction of a sealed chamber with a propeller agitator. The flow field can be formed by stirring the cooling water through the motor driving blade to enhance the heat transfer. To verify the effect of the radiator, The experimental platform is built and the solid heat sink with the same shape is designed and compared with the model. Different temperature-time curves are obtained by adjusting the working power of the heat source. When the input power of the heat source is 116W and the room temperature is 27 鈩,
