高热流密度器件水冷散热器结构性能的实验研究
Experimental study on water-cooled radiator structure performance of high heat flux device
摘要
Abstract
Compared with parallel flow cooling,the report of impinging jet cooling has rarely be seen. To study the heat dissipation performance of impinging jet cooling,two radiator were designed in this study. Test bench was built. The cooling medium was deionized water. The temperature variations of CPU chip and radiator bottom plate in different condition were measured by changing the heat flux and cooling water flow. The temperature change of CPU chip and radiator bottom plate was analyzed. By monitoring the inner fin structure anf flow direction of cooling water, the average temperature of CPU could drop 5 to 8℃ and 4℃ for the radiator bottom plate. In addition,the variation range of heat resistance was diminished gradually with the increase of cooling flow. Heat resistance of radiator reduced by 7%—8% due to improvement of radiator structure. The results showed that improvement of radiator structure effectively strengths the disturbance of the corner area and increases heat transfer efficiency of radiator. The present study indicates that impinging jet cooling is a high efficiency radiating way.关键词
