摘 要: 为解决车用电子元件的散热问题,设计了一种微小尺度射流冲击锥体热沉散热模型。通过改变热源的热流密度、射流高度与喷口直径比值(H/d)、锥体热沉顶角的角度,研究上述参数对其散热效果的影响。模拟结果表明,H/d=6、椎体热沉顶角为60°的射流结构具有十分良好的散热能力,当热流密度为6.3×107 W/m2时,可以将热源最高温度降低到372.15 K以下。
关 键 词: 流体传动与控制;微小尺度;射流冲击;锥体热沉;数值模拟

Abstract: In this paper, one kind of micro-scale jet impingement cooling model with cone heat sink is designed, which is used to solve the problem of heat dissipation in automotive chip. Through the changing on the heat flux density, the ratio of the jet height to the diameter of the jet nozzle (H/d), cone heat sink vertex angle, the influence of these on the heat dissipation effect is studied. The simulation results indicate that the jet structure with condition that H/d is 6 and cone heat sink vertex angle is 60° has great ability of heat dissipation. When heat flux density is 6.3×107 W/m2, the maximum temperature of heat source can be controlled under 372.15 K.
Key words: fluid power and control; micro-scale; jet impingement; cone heat sink; numerical simulation
