Heat exchanger

Abstract

A heat exchanger is provided, in particular for a motor vehicle, with at least one thermoelectric element to generate a heat flow, wherein the thermoelectric element is arranged on a carrier element, wherein several carrier elements arranged on top of one another along a stacking spindle form a carrier element stack, in which a first fluid channel for a first fluid and a second fluid channel for a second fluid, fluidically separated from the first, are constructed.

What is claimed is: 
     
         1 . A heat exchanger for a motor vehicle, the heat exchanger comprising:
 a carrier element;   at least one thermoelectric element to generate a heat flow, the thermoelectric element being arranged on the carrier element, wherein a plurality of carrier elements arranged on top of one another along a stacking spindle form a carrier element stack;   a first fluid channel for a first fluid; and   a second fluid channel for a second fluid, the second channel being fluidically separated from the first fluid channel.   
     
     
         2 . The heat exchanger according to  claim 1 , wherein a bottom element and a cover element are provided that close the carrier element stack at an end thereof. 
     
     
         3 . The heat exchanger according to  claim 1 , wherein the carrier element has a synthetic material frame in which the first fluid channel and the second fluid channel are formed. 
     
     
         4 . The heat exchanger according to  claim 1 , wherein the carrier elements have an essentially polygon, a rectangular, or octagonal outer boundary line. 
     
     
         5 . The heat exchanger according to  claim 1 , wherein the carrier element is constructed as a flat building component, wherein a level formed parallel to the stacking spindle of the carrier element is smaller than a dimension of the flat extension in a carrier element level. 
     
     
         6 . The heat exchanger according to  claim 1 , wherein the carrier element has a plurality of windows formed by an arrangement of braces or bridges. 
     
     
         7 . The heat exchanger according to  claim 1 , wherein isolation devices are provided in the carrier element, which thermally and mechanically each separate the first fluid channel and the second fluid channel from one another. 
     
     
         8 . The heat exchanger according to  claim 1 , wherein the first fluid channel and the second fluid channel each have a first and a second partial fluid channel, and wherein each of the first and the second partial fluid channel are connectable to one another by at least one overflow opening in the carrier element. 
     
     
         9 . The heat exchanger according to  claim 1 , further comprising connecting elements to connect the first and/or the second fluid channel with a first and/or a second fluid circuit, the connecting elements being arranged on a bottom element and/or on a cover element. 
     
     
         10 . The heat exchanger according to  claim 1 , wherein the thermoelectric element is a Peltier element. 
     
     
         11 . The heat exchanger according to  claim 1 , wherein the thermoelectric element has a friction-locked or substance-bonded connection with the carrier element or wherein the thermoelectric element is pressed or glued with the carrier element. 
     
     
         12 . The heat exchanger according to  claim 1 , wherein a fluid tight connection is provided between the carrier elements of the carrier element stack and/or the carrier element and the thermoelectric element. 
     
     
         13 . The heat exchanger according to  claim 1 , wherein the carrier elements stacked on top of one another are facing a same direction or are each arranged at a rotation of about 90° to a stacking spindle. 
     
     
         14 . The heat exchanger according to  claim 1 , further comprising flat tubes that are in contact with the thermoelectric elements and are connected fluid tight with the carrier element. 
     
     
         15 . The heat exchanger according to  claim 1 , wherein the carrier element is formed of a material, which includes synthetic material and/or several material elements. 
     
     
         16 . The heat exchanger according to  claim 1 , wherein the carrier element stack is enclosed by a special section tube.
