一、化学热管的原理[见图1]热管的原理已为人们所通晓,而化学热管似乎是一个新鲜的名称。众所周知,普通热管是利用密闭在管内工质液相和气相之间相变的热焓变化来实现热能的传递的。而化学热管是利用化学反应的焓变来替代相变的焓变来实现热能传递。因此这种热管被认为是一种化学反应装置。普道热管在形式上有类似之处,但是其工作过程有本质上的区别。 First, the principle of chemical heat pipe [see Figure 1] The principle of heat pipe has been well-known, and chemical heat pipe seems to be a fresh name. As we all know, the ordinary heat pipe is closed by the use of liquid in the tube phase change between liquid and vapor phase enthalpy changes to achieve the transfer of heat energy. The chemical heat pipe is the use of chemical reaction enthalpy change to replace the phase change enthalpy change to achieve heat transfer. Therefore, this heat pipe is considered a chemical reaction device. Puda heat pipe in the form of similarities, but the working process is essentially different.
