Development of the Loop Heat Pipe (LHP)

First, I describe the basic equations that resolve the physical development of the LHP and how to estimate the maximum heat transfer capability of the LHP. Second, I describe the outline of experimental manufacture of the LHP. This LHP is made from copper. The evaporator is φ19×95mm, the vapor tube is φ5×300mm, the condenser is φ3.5×600mm and the liquid tube is φ3.5×300mm. The wick is made from the sintering cupper. The working fluid is methanol. Finally, I briefly describe the test result of heat transfer capability of this LHP.
