双面三角形和矩形通道平板脉动热管的传热性能

摘要

The influence factors include the effects of filling ratio, oblique angle, working fluid, heating power and start-up temperature on the thermal performance of the PHP. The heat transfer performances of two new types of flat plate pulsating heat pipe (PHP) with double sides triangular and rectangular channel were studied. The results show that these two kinds of the PHP can work stably and have good thermal performance. However, the heat transfer performance of the PHP with triangular channel has better performance than rectangular channel.%研究充液率、倾角、工质、加热功率、启动温度对双面三角形和双面矩形2种通道的平板脉动热管传热性能的影响.研究结果表明:双面矩形平板脉动热管和双面三角形平板脉动热管都具有工作稳定与良好的传热性能,但三角形截面热管的传热性能比矩形截面热管的传热性能优.
