ANISOTROPIC POROUS FIN

摘要

PURPOSE: An anisotropic porous fin is provided to reduce the loss of pressure remarkably while maintaining the heat transmitting performance of an isotropic porous fin. CONSTITUTION: An anisotropic porous fin has multiple long holes(21,23) formed on a porous member(25) having many porosities formed uniformly while passing through the inner part of the porous member in parallel at a certain interval. Herein, the porous member is formed of aluminum or copper, and has 88% of porous degree and formed of foam metal over 100W/mK of heat conductivity. And the long holes formed on the porous member is formed by drilling work or laser processing work.
