A flat heat pipe for use as a cold side heat sink

Heat pipe technology can effectively meet the demand for an isothermal emitter in a thermophotovoltaic (TPV) energy conversion system as it utilizes near isobaric phase changes to transfer heat at a uniform temperature. A flat heat pipe offers many advantages over the conventional cylindrical design, such as increased surface area to volume ratio and the ability to stack or layer the energy conversion system on both sides of the flat heat pipe to utilize available energy. Flat heat pipes present unique engineering demands and are also difficult to construct. This paper details the design, construction and partial analysis of a low temperature flat heat pipe as part of the thermal sink in order to determine the feasibility of implementing flat heat pipes into TPV energy conversion systems.
