摘　　要：某刀片服务器机箱中主板中央处理器(Central Processing Unit,CPU)冷板采用铜质肋片散热器实现了国产CPU的热设计,但4块铜质冷板给整机增加了较大的重量。为了解决冷板重量影响设备的拆装和维护的问题,结合冷板结构特点,先后设计生产了不同结构形式的热管冷板和均温板冷板。通过ANSYS Workbench仿真手段,对铜质纯金属冷板、热管冷板和均温板冷板在机箱中的散热性能进行了仿真分析,并结合仿真结果对各型冷板在机箱中的实际散热效果进行了测试验证。结果表明,均温板不仅可实现国产CPU的有效散热,还能降低设备重量,实现了对原机箱冷板的优化设计。The main board central processing unit(CPU)cold plate in a blade server chassis adopts a copper ribbed radiator to achieve the thermal design of domestic CPU,but the four copper cold plates increase weight of the whole machine significantly.In order to solve the problem that the cold plate weight affects disassembly and maintenance of the equipment,combined with the structural characteristics of cold plates,heat pipe cold plates and uniform temperature plate cold plates in different structural forms have been designed and produced.The heat dissipation performance of pure metal(copper)cold plates,heat pipe cold plates and uniform temperature plate cold plates in the chassis are simulated and analyzed by ANSYS Workbench.Based on the simulation results,the actual heat dissipation effects of each type of cold plate in the chassis are tested and verified.The results show that the uniform temperature plate can not only achieve effective heat dissipation of domestic CPU,but also reduce equipment weight and thus optimize the design of original chassis cold plate.
