definition for: #HeatPipes

AMSEnergy. Isothermal heat transfer device used in a Heat Pipe Heat Exchanger. It is an evacuated hermetically sealed tube with an internal working fluid that will change into a vapor state with any small increase in temperature in the evaporating end of the tube. The vapor will rise to the top of the heat pipe referred to as the condenser end where it will give up its heat to the colder thermal energy stream passing by. After giving up its heat,the vapor will then condense and fall back to the evaporating end where it will repeat the same cycle at almost supersonic speed.
