  • Abstract With the rapid development of the electronic manufacturing technologies, the operating frequency of CPU has also increased. This leads to higher power and heat dissipation per unit area. However, the higher temperature will cause higher thermal resistance to impact the CPU calculation performance and reduce computer's efficiency. Reducing the operating temperature of CPU can avoid the chip failure, providing higher temperature stability and computer's efficiency. Therefore, the thermal management has become key point of all the computer industries.
    This article analyzed three types of waterblock: S-type, fin-type, and Side-type. S-type and fin-type are manufactured by copper, Side-out type is combined with plastic cover and the copper plate. After verified by numerical simulation and experimental results of these tree types of waterblock, the conclusion can be summarized as follows: thermal resistances of S-type, Side-out type, and fin-type are 0.223,0.229,and 0.231℃/W, respectively. The results of numerical simulation and experimental data in these tree types of waterblock have the same heat cooling feature. The methods of numerical simulation and experimental measurement have been proved as useful tools in the product design.
