前言热管(包括无吸液芯的重力热管)目前在能源工程的各个领域中得到了相当广泛的应用。一般公认:1942年由美国高格勒(Gaugler R.S.)首先提出热管的概念,以“传热器件”为名申请了专利,1944年正式发表,未引起重视。1964年美国格罗弗(Grover G.M.)等人正式以热管为名,独立提出了发明后,才得到了迅速的发展。实际上,如果广义地理介热管的应用,历史可以上溯到前一个世纪。按照最近日本Oshima教授的定义,热管是一个封闭的依靠工质相变的传热元件。 Preface Heat pipes (including gravity heat pipes without wick) are currently used in a wide range of applications in all fields of energy engineering. It is generally acknowledged that the concept of heat pipe was first proposed by Gaugler R.S. in 1942 and patented in the name of heat transfer device. It was officially published in 1944 and did not attract much attention. In 1964, when Grover G.M. and others were formally known as heat pipes, the invention was rapidly developed only after the invention was proposed independently. In fact, history can be traced back to the previous century if the geophysical heat pipe is broadly applied. According to a recent Japanese professor Oshima’s definition, a heat pipe is a closed heat transfer element that relies on phase transitions.
