POROUS ALUMINUM OBJECT, HEAT TRANSFER MATERIAL, AND HEAT EXCHANGER

摘要

Provided is a porous aluminum body capable of being used as a heat transfer material having a very large specific surface area, a good heat-exchange efficiency, and a low pressure drop of a gas. The porous aluminum body contains aluminum as a main component. The porous aluminum body has a three-dimensional network structure and has a specific surface area (Y) represented by a (Formula) below.
(In the (Formula), Y represents a specific surface area [m 2 /m 3 ], X represents the number of cells [per inch], and a represents a number of 100 or more and 1,000 or less.)
