热管子总是在高热流动在电子的热驱散的典型应用程序被弄弯,它极大地影响它的热转移性能。在弄弯的 micro-grooved 热管子中的热运输的毛状的限制在蒸汽压力落下,液体压力落下和和灯芯液体的蒸汽的相互作用被分析。弄弯的热管子从弯曲角度,弯曲位置和弯曲半径被制作并且测试。当热管子的热转移能力减少时,结果显示出那温度差别和热抵抗增加,随更近到蒸汽节的弯曲角度和弯曲位置的增加。然而,把半径弄弯的效果能被忽略。结果与预言的方程同意很好。
Heat pipe is always bent in the typical application of electronic heat dissipation at high heat flux, which greatly affects its heat transfer performance. The capillary limit of heat transport in the bent micro-grooved heat pipes was analyzed in the vapor pressure drop, the liquid pressure drop and the interaction of the vapor with wick fluid. The bent heat pipes were fabricated and tested from the bending angle, the bending position and the bending radius. The results show that temperature difference and thermal resistance increase while the heat transfer capacity of the heat pipe decreases, with the increase of the bending angles and the bending position closer to the vapor section. However, the effects of bending radius can be ignored. The result agrees well with the predicted equations.
