FEASIBILITY OF POROUS COPPER FIBER SINTERED SHEETS (PCFSSS) IN A PLATE HEAT EXCHANGER FOR ENHANCING HEAT TRANSFER
Краткое описание
In order to enhance the heat transfer performance of a plate heat exchanger, porous copper fiber sintered sheets (PCFSSs) with a three-dimensional (3D) network structure has been developed. Slim copper fibers are manufactured with a new type of multi-tooth tool. Then, they are pressed and sintered in a designed mold to produce the PCFSSs. In addition, the heat transfer performance and the pressure drop of the plate heat exchanger are investigated experimentally. The results show that copper fibers with a rough surface can be manufactured efficiently. PCFSFs with a 3D network structure can be successfully machined. Moreover, PCFSSs with porosity of 70% nearly quadruple the heat transfer performance and PCFSSs with porosity of 90% are optimum, considering both the heat transfer performance and the pressure drop.
