某高热流密度冷板的设计与优化

某吸收电阻模块发热功率大且热流密度高,冷却系统的设计既是重点也是难点,冷却系统的好坏直接关系到模块能否正常工作。文中探讨了某高热流密度与大发热功率并存的散热问题,选择强迫液冷作为其冷却方式。通过仿真分析对冷板结构进行不断的优化,通过增加散热齿并改变散热齿结构,使冷板满足器件散热需求。运用ANSYS模拟了冷板盖板不同结构形式的密封性能,通过采用有筋的不锈钢盖板,可取得良好的密封性能,缩短冷板加工周期并降低成本。装机后对该冷板的实物测试证明了该冷板的可行性。

Design and Optimization of a Cold Plate with High Thermal Density

The resistance module has large power and too concentrated heat consumption. The design of the cooling system for the module is both important and difficult. The quality of the cooling system is directly related to the work of the module. The module with both great thermal density and large power is discussed in this paper. The forced liquid cooling is chosen as its cooling method. Then constant optimization for the design of the cold plate is carried out by simulation. By adding heat dissipation teeth and modifying their structures, the heat dissipation demands of the cold plate are satisfied. ANSYS is used to simulate the sealing performance of the cold plate with different structures and forms. By adopting stainless-steel cover plate with stiffeners, good sealing performance is obtained and the manufacturing cycle and cost of the cold plate are reduced. After installation, the prototyoe test of the cold plate indicates its feasibilitv
