POROUS ALUMINUM OBJECT, HEAT TRANSFER MATERIAL, AND HEAT EXCHANGER

摘要

Provided is porous aluminum object utilizable as a heat transfer material which has an extremely large specific surface area and an excellent heat exchange efficiency and is reduced in pressure loss of gases. The porous aluminum object comprises aluminum as the main component, has a three-dimensional network structure, and has a specific surface area (Y) represented by the equation. Y=a×exp(0.06X) (Equation) (In the equation, Y represents the specific surface area [m2/m3], X is the number of cells [cells/inch], and a is a number of 100-1,000.)
