前言热管是一种结构简单、无运转部件、工作可靠、使用寿命长、传热效率极高的新型传热元件。按结构不同,可分为吸液芯热管和热虹吸热管。两者工作原理基本相同,所不同的是工质冷凝液回归方法:前者依靠吸液芯的毛细作用,而后者依靠液体的重力。热虹吸热管制作较为简便,成本较低,传输热量大,应用较多。热管用作换热器、 Preface Heat pipe is a new type of heat transfer element with simple structure, no moving parts, reliable working, long service life and high heat transfer efficiency. According to the different structure, can be divided into suction wick heat pipe and thermosyphon heat pipe. The working principle of the two is basically the same, the difference is the working fluid condensate regression method: the former relies on the capillary action of the wick, while the latter relies on the liquid’s gravity. Thermosyphon heat pipe production is relatively simple, lower cost, heat transfer, more applications. Heat pipe used as a heat exchanger,
