Manufacturing heat exchanger from porous medium and conduits

摘要

The present invention relates to a method for producing a heat exchanger. The heat exchanger comprising at least one heat conducting conduit for passage of a first medium and at least one block of an open cell porous medium for passage of a second medium. The method comprises providing at least one groove in the open cell porous medium. Thereafter, the porous medium is bent in a direction such that at least part of the grooves are opened and heat conducting conduits are applied in this at least one opened groove. Thereafter, the porous medium is rebend such that the heat conducting conduits are locked in said open cell porous medium.

1. A method of producing a heat exchanger, said method comprising:
providing a plurality of heat conducting conduits configured to permit passage of a first medium, including at least one heat conducting conduit comprising a metal tube; providing at least one block of an open-cell porous medium of open-cell metal foam configured to permit passage of a second medium; providing a first plurality of grooves in said porous medium such that the porous medium becomes grooved, and such that the first plurality of grooves are disposed in a first orientation and in a same alignment relative to each other; bending said grooved porous medium in a direction, such that at least a plurality of said grooves are opened; applying said plurality of heat conducting conduits in said at least a plurality of opened grooves; and bending said grooved porous medium in an opposite direction such that said plurality of heat conducting conduits get locked in said open-cell porous medium.
