| Along with the power density of the electronic device sharply increased, the traditional cooling methods of the natural cooling and the forced-air cooling can't satisfy the need of the electronic device's thermal design. The cold-plate which was extensively applied in the cooling system of the electronic device was one of the highly effective and mature heat transfer equipments. In this paper, heat transfer and fluid flow characteristics of liquid cold-plate are investigated by numerical and experimental methods.This thesis is mainly composed of following three parts:1. Compare with the results of two different cold-plate with different fin, we find that they both have highly Heat transfer efficiency.2. The heat transfer of fin was investigated with numerical simulation package-FLUENT firstly. According to the comparison of the results between numerical method and experiment, it indicates that the numerical simulation can be used to investigate this problem and the relative computational method and turbulence model was chosen.3. The performance of the cold-plate system was studied with computational method, and the results agree well with the experimental data.Compared with experimental method, the numerical method can give detailed flow field in the cold plate and the temperature contour in the base skin, which makes it possible to analyze the method to improve the performance of cold-plate system. The research in this thesis provides a way for the performance optimization of cold-plate system.
