近年来由于电路和元器件技术的发展,电子设备的元器件密度增加,单位体积内产生的热量也增加,而有效的散热表面却相应缩小,使电子元器件由于得不到良好的散热而不能满功率工作。因此,需要有更好的散热方法来代替传统的散热法。热管就是一种值得推荐的高效传热元件,它可用来散热,但又不需要动力,而且结构简单,无噪音,目前正在逐渐被人们所采用。目前除了发展管状热管外,尚有平板状热管、挠性热管、旋转热管和控制型热管等等。本文将对一般热管的构造和工作原理加以叙述,并对热管在航空电子组装件上的应用,举例加以说明。
In recent years due to the development of circuit and component technology, the density of electronic components increases, the heat generated per unit volume also increases, while the effective cooling of the surface is reduced accordingly, so that the electronic components can not get good heat dissipation can not Full power work. Therefore, there is a need for a better heat dissipation method instead of the traditional heat dissipation method. Heat pipe is a highly recommended heat transfer element, it can be used to heat, but does not require power, and the simple structure, no noise, is now gradually being adopted by people. In addition to the current development of tubular heat pipe, there are flat-shaped heat pipe, flexible heat pipe, rotating heat pipe and control heat pipe and so on. This article will be general heat pipe structure and working principle to be described, and the heat pipe in the avionics assembly on the application, to illustrate.
