Manifold profile

Abstract

A manifold profile of a heat exchanger. The manifold profile includes two side walls, a top wall connecting the two side walls, a collecting space enclosed on three sides by the two side walls and the top wall, a receiving opening configured to receive a connection piece, the receiving opening being located on one or more of the two side walls and the top wall.

We claim: 
     
         1 . A manifold profile of a heat exchanger, the manifold profile comprising:
 two side walls;   a top wall connecting the two side walls;   a collecting space enclosed on three sides by the two side walls and the top wall;   a receiving opening configured to receive a connection piece, the receiving opening being located on one or more of the two side walls and the top wall; and   wherein the one or more of the two side walls and the top wall including fastening holes configured to accommodate fastening means for fastening the connection piece to the one or more of the two side walls and the top wall.   
     
     
         2 . The manifold profile according to  claim 1 , wherein the fastening holes include an internal thread. 
     
     
         3 . The manifold profile according to  claim 1 , wherein the fastening holes are configured as pocket holes. 
     
     
         4 . The manifold profile according to  claim 1 , wherein a first wall thickness of one or both of the side walls and the top wall is larger in a region of the fastening holes than a second wall thickness of one or both of the side walls and the top wall in a region without the fastening holes. 
     
     
         5 . The manifold profile according to  claim 1 , wherein a first of the side walls converges towards the collecting space in a concave manner and is shaped with a constant wall thickness into the top wall, whereas a wall thickness of a second of the side walls is arranged together with the top wall in such a way that the second of the side walls, together with the top wall, forms a rectangular triangle in the cross section, and an outside of the second of the side walls facing away from the collecting space and the top wall are perpendicular to each other, and the fastening holes are provided in the region of the second of the side walls and the top wall. 
     
     
         6 . The manifold profile according to  claim 1 , wherein a wall thickness of the side walls is arranged together with the top wall in such a way that each of the side walls forms a rectangular triangle in the cross section together with the top wall. 
     
     
         7 . The manifold profile according to  claim 5 , wherein a hypotenuse of the second of the side walls is formed into a rectangular triangle together with the top wall and is arranged as an undulating line. 
     
     
         8 . The manifold profile according to  claim 1 , wherein the manifold profile is arranged as an integral extruded profile. 
     
     
         9 . The manifold profile according to  claim 1 , wherein the connection piece is fastened in an interlocking engagement. 
     
     
         10 . The manifold profile according to  claim 1 , wherein the connection piece is fastened in a frictionally engaged manner. 
     
     
         11 . The manifold profile according to  claim 6 , wherein a hypotenuse of each of the side walls is formed into a rectangular triangle together with the top wall and arranged as an undulating line.
