Optimization of rectangular pin fin heat sinks during air jet impingement
摘要
Abstract
The experimental and numerical method was done in the process of optimization of rectangular pin fin heat sink. The thermal resistance of a series of rectangular pin fin heat sinks with different fin height and width was experimented and calculated by the k-ε model. The results show that the thermal resistance decreases as Renolds number (Re) and nozzle height-diameter ratio (H/D) increase, but this tend becomes less obvious as Re and H/D increase to some extent.When fin height scope of heat sink is between 15 and 21 mm, the balance of cooling ability and economical efficiency are reached. Comparing the simulation results with the experimental results, the correlated error does not exceed 10%.关键词
