Abstract
A structural heat-exchange element has a structural part including a body portion of ceramic foam material and outer wall portions spaced from one another in a first direction so as to laterally outwardly bound the body portion and having a higher thermal conductivity than the latter, and conduit elements for passing a heat-carrying medium through the structural part and formed by a plurality of passages extending in the structural part in a second direction transverse to the first direction and each having at least an outer wall which is formed by the outer wall portion constituted of the material having a higher thermal conductivity.
Claims21
A structural heat-exchanger element, comprising a structural part including a body portion of a ceramic foam material and outer wall portions spaced from one another in a first direction so as to laterally outwardly bound said body portion, at least one of said outer wall portions being constituted of a material having a higher thermal conductivity than the material of said body portion;
- and conduit means for passing a heat-carrying medium through said structural part, said conduit means being formed by a plurality of passages extending in said structural part in a second direction transverse to said first direction, each of said passages having at least an outer wall which is formed by said one outer wall portion constituted of the material having the higher thermal conductivity, said one outer wall portion being constituted of the same cermaric foam material of which said body portion is constituted but with the higher thermal conductivity, and being of one piece with said body portion.
