Claims (14)

A heat exchanger comprising a first plurality of conduits for a first fluid and a second plurality of conduits for a second fluid,
The first conduit and the second conduit are formed so as to be separated from each other by a thermally conductive solid base material, embedded in the solid base material, and between the adjacent first and second conduits. The heat exchanger is much larger than the gap between adjacent first conduits and the gap between adjacent second conduits.   2. A heat exchanger according to claim 1 wherein adjacent first conduits are in contact and / or adjacent second conduits are in contact.   2. A heat exchanger according to claim 1, wherein metal flakes are arranged between adjacent first conduits and / or between adjacent second conduits.   4. A heat exchanger according to claim 1, 2, or 3, wherein each of the first conduit and / or the second conduit has a rectangular cross section.   The heat exchanger according to any one of claims 1 to 4, wherein the solid base material forms a plate between the first and second conduits, each conduit being in contact with the plate.   The heat exchanger according to any one of claims 1 to 5, wherein the solid base material is made of copper.   The heat exchanger according to any one of claims 1 to 6, wherein each of the first conduits and / or each of the second conduits is made of stainless steel.   8. A heat exchanger according to any one of the preceding claims, wherein at least one conduit is coupled to the solid matrix while the solid matrix is formed.   9. The heat exchanger according to claim 8, wherein each of the first conduits and each of the second conduits are coupled to the solid preform while the solid preform is formed.   The heat exchanger according to any one of claims 1 to 9, wherein the first conduit is formed with a larger flow area than the second conduit.   11. A heat exchanger according to claim 10, wherein the first and second conduits have substantially equal surface areas adjacent to the plate. A method of forming a heat exchanger according to any one of claims 1 to 12, comprising:
A high temperature equilibrium pressure technique is used to couple the metal disposed between the first conduit and the second conduit to the first and second conduits, and the first conduit and the second conduit A method in which a solid matrix is formed between the two.   14. The method according to claim 13, wherein the solid matrix is bonded to the surface of at least one conduit while the solid matrix is formed. 15. The method according to claim 14, wherein the solid matrix is bonded to the surface of each of the first and second conduits during the formation of the solid matrix.
