Heat exchanger

Abstract

A heat exchanger for exchanging heat between two media in a vehicle is provided. The heat exchanger includes at least one tube, especially a double-walled tube for carrying a first medium of a first temperature, a thermoelectric material being disposed on an inner wall of the tube, and at least one guide sheet, connected to the at least one tube, for carrying a second medium of a second temperature. The at least one guide sheet is designed to carry the second medium to the outer wall of the at least one tube to allow the exchange of heat between the first and the second medium.

1 . A heat exchanger for exchanging heat between two media in a vehicle, the heat exchanger comprising:
 at least one tube configured to guide a first medium of a first temperature,   a thermoelectric material disposed between an inner wall of the tube and an outer wall of the tube or on an inner wall of the tube; and   at least one guide sheet connectable to the at least one tube for guiding a second medium of a second temperature, the at least one guide sheet configured to guide the second medium to the outer wall of the at least one tube to enable the exchange of heat between the first medium and the second medium.   
     
     
         2 . The heat exchanger according to  claim 1 , wherein the guide sheet has at least one recess, and wherein the tube is accommodated by the recess. 
     
     
         3 . The heat exchanger according to  claim 1 , wherein a second tube is arranged substantially parallel to the tube on a first common plane, and a third tube is arranged on a second plane which is parallel to the first plane, the third plane being disposed on the second plane in a position at which a passage is provided between the tube and the second tube on the first plane. 
     
     
         4 . The heat exchanger according to  claim 1 , wherein the inner wall forms a guide channel for the first medium, wherein the inner wall has protrusions in the guide channel, and/or wherein the outer wall has raised structures in a direction of a flow area of the second medium. 
     
     
         5 . The heat exchanger according to  claim 1 , wherein the guide sheet has a profiling. 
     
     
         6 . The heat exchanger according to  claim 5 , wherein the profiling is a plurality of elongated raised structures, the plurality of raised structures being arranged on the guide sheet such that a meandering guidance of the second medium around multiple tubes is facilitated. 
     
     
         7 . The heat exchanger according to  claim 5 , wherein the guide sheet has a profiling in the form of a plurality of protrusions, the guide sheet being arranged adjacent to another guide sheet having a profiling in the form of a plurality of protrusions, the protrusions of the profiling of the guide sheet engaging on a back with the protrusions of the profiling of the additional guide sheet. 
     
     
         8 . The heat exchanger according to  claim 5 , wherein the guide sheet is arranged adjacent to at least one additional guide sheet having a profiling, the profiling of the guide sheet and the profiling of the additional guide sheet having a same structure and facing a same raising direction, the additional guide sheet being rotated 180 degrees with respect to a normal to the guide sheet. 
     
     
         9 . The heat exchanger according to  claim 5 , wherein the guide sheet is disposed adjacent to at least one additional guide sheet having a profiling, the profiling of the guide sheet and the profiling of the additional guide sheet facing each other. 
     
     
         10 . The heat exchanger according to  claim 1 , wherein the at least one guide sheet is uneven in an area of the passages in the tube. 
     
     
         11 . The heat exchanger according to  claim 1 , wherein the at least one tube is a double-walled tube. 
     
     
         12 . The heat exchanger according to  claim 2 , wherein the second tube and the third tube are double-walled tubes.
