摘要
大型计算机服务器的CPU作为高热流密度器件的典型代表,其冷却问题至关重要,为提高对CPU芯片的冷却效率而提出了一种冷凝段带有翅片的热管型散热器。利用自建实验台,在相同的工况条件下与效能较高的平板式热管散热器进行了对比实验研究。通过散热器总热阻、扩散热阻的实验对比和数值分析认为:在服务器空间条件允许情况下,这种带有强化换热的新型散热器更能满足大型计算机CPU的冷却要求。
The cooling requirement of computer server is very important. In order to improve the cooling efficiency, a new type of radiator with heat pipes in both bottom plate and fin was designed. We focused on the performance test between plate type radiator and heat pipes radiator with a enhancement condensation section under same working conditions through text bench of heat dissipating performance of the high heat flux component. Through the contrast of total thermal resistance and diffusion heat resistance and numerical calculation, It shows that under the condition of server space condition ,the cooling requirement of computer server can be more satisfied by the heat pipes radiator with a enhancement condensation section.
