Heat exchanger

Abstract

A heat exchanger may include a plurality of layers arranged on top of each other, each of the layers having a first cavity for the passage of a medium and a second cavity for the passage of a coolant. Each layer may define a through hole for the passage of the medium and each layer may include a frame in which a turbulence insert may be inserted. Each frame may have an end region configured to define at least one channel closure and the through holds for the passage of the medium. The frame may have a guide opening for receiving an assembly aid and the guide opening may be formed between the through holes and the channel closure.

         6 . heat exchanger according to  claim 1 , wherein the first through hole is fluidly connected to an inlet of the medium to be cooled and the second through hole is fluidly connected to an outlet of the medium to be cooled and further wherein the first through hole and the second through hole are formed in the frame and arranged diagonally opposite each other. 
     
     
         7 . The heat exchanger according to  claim 1 , wherein two of the frames are in a first predetermined position, and at least one other of the frames is arranged between the two frames and is in a second predetermined position at least one of turned or rotated relative to the first position. 
     
     
         8 . The heat exchanger according to  claim 1 , wherein the frame has at least one marking pin on its outer edge. 
     
     
         9 . The heat exchanger according to  claim 2 , wherein the frame completely encloses the turbulence insert and has an approximately rectangular shape. 
     
     
         10 . The heat exchanger according to  claim 9 , wherein a separating arrangement is inserted between at least two of the layers, each layer including the frame and the turbulence insert. 
     
     
         11 . The heat exchanger according to  claim 10 , wherein the separating arrangement is formed in a plate-like manner and has a solder layer on both sides. 
     
     
         12 . The heat exchanger according to  claim 11 , wherein the first through hole is fluidly connected to an inlet of the medium to be cooled and the second through hole is fluidly connected to an outlet of the medium to be cooled and further wherein the first through hole and the second through hole are formed in the frame and arranged diagonally opposite each other. 
     
     
         13 . The heat exchanger according to  claim 12 , wherein two of the frames are in a first predetermined position, and at least one other of the frames is arranged between the two frames and is in a second predetermined position at least one of turned or rotated relative to the first position. 
     
     
         14 . The heat exchanger according to  claim 13 , wherein the frame has at least one marking pin on its outer edge. 
     
     
         15 . The heat exchanger according to  claim 2 , wherein a separating arrangement is inserted between at least two of the layers, each layer including the frame and the turbulence insert. 
     
     
         16 . The heat exchanger according to  claim 2 , wherein the separating arrangement is formed in a plate-like manner and has a solder layer on both sides.
