摘要
为了研究流量和翅片结构对翅片式液冷板的传热特性的影响规律,本文基于CFD方法,采用SolidWorks Flow Simulation软件,对直通形翅片和锯齿形翅片式液冷板进行仿真分析。研究表明,保持翅片当量直径和高度不变,且流量为1 L/min时,将直通形翅片更换为节距t=5 mm的锯齿形翅片时,流阻从3.1 kPa增大到了3.26 kPa,增大了0.16 kPa,增长率约为7.5%,而要达到相当的制冷效果,直通形翅片冷板的流量需要从1 L/min提高到3 L/min时,而流阻从3.1 kPa提高到了23.1 kPa,增大了20 kPa,增长率约645%。因此,对于翅片式液冷板而言,通过改变翅片结构来改善制冷效果,比提高流量的方式更具有优势。
In order to study the influence of flow rate and fin structure on the heat transfer characteristics of the finned liquid-cooling plate,this paper uses SolidWorks Flow Simulation software to simulate and analyze the liquid-cooling plate with straight-through fin/serrated fin based on CFD method.The research shows that when the equivalent diameter and height of the fin are kept constant and the flow rate is 1 L/min,the flow resistance increases from 3.1 kPa to 3.26 kPa(7.5%)when replacing the straight-through fin with a serrated fin with a pitch of 5 mm.In order to achieve equivalent cooling effect,the flow rate of the straight-through fin cooling plate needs to be increased from 1 L/min to 3 L/min,while the flow resistance increases from 3.1 kPa to 23.1 kPa(645%).Therefore,for the finned cooling plate,it is more useful to improve the cooling effect by changing the fin structure than by increasing the flow rate.
