Sustainable Cooling Method of CPU Hot Spot Based on Target Matrix

为了解决CPU发热导致的自身过热问题,很多学者都提出了各自的CPU降温模型,以实现绿色节能。在已有的热量循环利用模型的基础上,定量分析了CPU热点可持续冷却模型成立的数学条件,建立了CPU降温过程中基于温度变化的目标热量矩阵模型,通过实验分析了热点区域的温度变化等特征,并验证了该数学关系模型的正确性;在比较已有热量循环利用模型的基础上,进一步提出了考虑系统自身散热因素的可持续冷却模型,该模型能够利用所提出的目标热量矩阵进行验证。实验表明,所提出的考虑自身散热的可持续冷却模型的冷却效率提高了0.937%。

In order to solve the CPU overheating problems,many scholars have proposed their own CPU cooling models to achieve energy saving.Based on the previous model of heat cycling,this paper quantitatively analyzed the mathematical conditions of the establishment of the CPU hotspot sustainable cooling model,established the target heat matrix model based on the temperature change during the CPU cooling process,analyzed the temperature change of the hot spot, and verified the correctness of the mathematical relation model.On the basis of comparing the previous models of heat recovery,a cooling model considering the self-heating factor of the system was proposed,which can be carried out by using our proposed target heat matrix.The experimental results show that the cooling efficiency of the cooling model is 0.937%.
