平板热管作为一种新型的热管技术,具有高热导率,良好的均温性等优点,成为解决大功率LED散热问题很有前途的技术之一。本文通过实验与数值模拟相结合的方法,研究了平板热管散热模组的传热性能,探讨了热源布置方式(集中式布置与分散式布置)的影响,为LED芯片的布置提供理论指导。结果表明:该平板热管散热模组的散热效果良好,能有效解决LED灯的散热问题。 As a new type of heat pipe technology, the flat heat pipe has the advantages of high thermal conductivity and good evenness, which is one of the promising technologies to solve the heat dissipation problem of high power LEDs. In this paper, the heat transfer performance of flat panel heat pipe cooling module is studied through the combination of experiment and numerical simulation. The influence of heat source arrangement mode (centralized arrangement and decentralized arrangement) is discussed to provide theoretical guidance for the arrangement of LED chips. The results show that the heat dissipation effect of the flat heat pipe cooling module is good and the heat dissipation problem of the LED lamp can be effectively solved.
