Heat exchangers comprising at least one porous member positioned within a casing
First Claim
1. A heat exchanger, comprising:
- a casing;
at least one porous member positioned within the casing, the at least one porous member comprising;
a porous wall comprising an inner wall defining an interior of the at least one porous member, the interior of the at least one porous member surrounded by the inner wall, and an outer wall, the outer wall of the porous wall and an inner wall of the casing defining a chamber therebetween, the porous wall further comprising a plurality of pores exhibiting interconnected porosity therethrough providing fluid communication between the interior of the at least one porous member and the chamber;
an inlet comprising a first opening into the interior of the at least one porous member, the first opening substantially larger than each of the plurality of pores; and
an outlet comprising a second opening into the interior of the at least one porous member, the second opening substantially larger than each of the plurality of pores and positioned such that fluid may flow from the inlet to the outlet through the interior of the at least one porous member without passing through the plurality of pores of the porous wall; and
an inlet through the casing into the chamber.

Abstract
A heat exchanger and associated methods for sublimating solid particles therein, for conveying fluids therethrough, or both. The heat exchanger includes a chamber, and a porous member having a porous wall having pores in communication with the chamber and an interior of the porous member. A first fluid is conveyed into the porous member while a second fluid is conveyed into the porous member through the porous wall. The second fluid may form a positive flow boundary layer along the porous wall to reduce or eliminate substantial contact between the first fluid and the interior of the porous wall. The combined first and second fluids are conveyed out of the porous member. Additionally, the first fluid and the second fluid may each be conveyed into the porous member at different temperatures and may exit the porous member at substantially the same temperature.
