热管是美国科学家1964年发明的。由于其导热系数比铜、银高上千倍,所以有人称它为超导热元件如果把同样1米长的热管和铜棒一端放在开水里,一端握在手里,几秒钟后,热管就烫得拿不住了,而铜棒却没什么感觉。热管外表看起来就是一根普普通通的管子,它由三个部分组成,管壳、吸液芯和工质。吸液芯是一种具
The heat pipe was invented by American scientists in 1964. Because its thermal conductivity is 1000 times higher than that of copper and silver, some people call it a superconducting element. If one end of the same one meter long heat pipe and copper rod is placed in boiling water, one end is held in the hand, and after a few seconds, The heat pipe was too hot to hold, and the copper bar didn’t feel much. The appearance of the heat pipe looks like an ordinary pipe. It consists of three parts, the tube, the wick and the working medium. The wick is a tool
