An Intercell Heat Pipe for Fuel Cell and Battery Cooling

A planar (rectangular cross section) heat pipe was designed to transfer 2000 watts at 115C plus or minus 12C. The evaporator area was fixed at 30.48cm by 12.7cm per side so that the design heat flux was 3.45 watts/sq cm. The heat pipe was tested with electrical heaters to simulate waste heat from tw...

Description
Summary:A planar (rectangular cross section) heat pipe was designed to transfer 2000 watts at 115C plus or minus 12C. The evaporator area was fixed at 30.48cm by 12.7cm per side so that the design heat flux was 3.45 watts/sq cm. The heat pipe was tested with electrical heaters to simulate waste heat from two adjacent high power density fuel cell or battery modules. The device was constructed from two milled copper plates which were electron beam welded to produce the completed structure. The finished heat pipe thickness was 1.27cm. A single layer of 100 mesh copper screen covered rectangular milled capillary grooves. Triply distilled, deionized water was chosen as the working fluid. (Modified author abstract)
