Casing for holding a fluid for a heat exchanger, method for producing a casing of this type and heat exchanger

Abstract

The invention relates to a casing for holding a coolant for a heat exchanger ( 1 ) for motor vehicles, said casing having two side walls ( 22, 24, and 22 a, 24 a ), two front walls ( 26, 28 and 26 a, 28 a ), a cover ( 18 and 18 a ) and a base ( 20 and 20 a ) lying opposite the cover ( 18 and 18 a ), said base being provided with one or more openings ( 60 ) for receiving tubes, According to the invention, the casing consists of a single formed, in particular folded, shaped part, said formed shaped part, in particular a sheet metal blank, forming the two side walls ( 22, 24 and 22 a, 24 a ), the two front walls ( 26, 28 and 26 a, 28 a ), the cover ( 18 and 18 a ) and the base ( 20 and 20 a ).

1 . A casing for holding a coolant for a heat exchanger for motor vehicles, comprising two side walls, two end walls, a cover, and a base arranged opposite the cover, in which one or more openings are provided for holding connecting tubes, wherein the casing is made from only one shaped, molded sheet metal part, wherein the shaped molded sheet metal part forms the two side walls, the two end walls, the cover and the base. 
   
   
       2 . The casing according to  claim 1 , wherein at least one of the side walls has an indentation, for holding a port. 
   
   
       3 . The casing according to  claim 1 , wherein the cover has a bulge that is adapted essentially to an indentation in the side walls. 
   
   
       4 . The casing according to  claim 1 , wherein one or more openings for holding connecting tubes are formed in the base. 
   
   
       5 . The casing according to  claim 1 , wherein the molded part has bending/flap or folding lines between two walls, across which the walls can be folded. 
   
   
       6 . The casing according to  claim 1 , wherein the shaped molded part is soldered. 
   
   
       7 . The casing according to  claim 1 , wherein at least one of the end walls has at least one bracket and/or assembly that is arranged, on the side and/or that can be angled. 
   
   
       8 . The casing according to  claim 7 , wherein the one or more brackets and/or assemblies are angled so that they are arranged essentially parallel to one of the side walls and/or are connected, by a solder connection with one of the side walls. 
   
   
       9 . The casing according to  claim 1 , wherein at least one, essentially triangular recess is formed in the molded part in a transition region between two walls. 
   
   
       10 . A heat exchanger, for a motor vehicle comprising a tube-rib block and a casing comprising two side walls, two end walls, a cover, and a base arranged opposite the cover, in which one or more openings are provided for holding connecting tubes, wherein the casing is made from only one shaped molded sheet metal part, wherein the shaped molded sheet metal part forms the two side walls, the two end walls, the cover and the base wherein the tubes of the tube-rib block open, in the region of the base of the casing into the casing. 
   
   
       11 . A method for producing a casing for holding a coolant, for a heat exchanger comprising producing a one-piece sheet metal part, by punching, wherein the one-piece sheet metal part includes walls that define an inner space of the casing and that are two side walls, two end walls, a cover, and a base arranged opposite the cover; and shaping the one-piece sheet metal part by bending or folding along given bending or folding lines to form an essentially closed casings; and, solder-plating the shaped, one-piece sheet metal part, wherein the casing is formed. 
   
   
       12 . The method according to  claim 11 , wherein shaping includes folding across an end wall or across two end walls. 
   
   
       13 . The method according to  claim 12 , wherein the one-piece sheet metal part is processed before or after the folding by a drawing method, and/or hydro-shaping, and/or mold pressing. 
   
   
       14 . The method according to  claim 11 , wherein the one-piece sheet metal part, in a region of the one-piece sheet metal part that forms the base in the casing, one or more openings are formed for holding connecting tubes. 
   
   
       15 . The method according to  claim 14 , wherein the one or more openings for holding tubes are formed before shaping the one-piece sheet metal part. 
   
   
       16 . The method according to  claim 14 , wherein one or more connecting tubes are inserted into the one or more openings. 
   
   
       17 . The method according to  claim 16 , wherein the one or more tubes are inserted into the one or more openings before shaping the one-piece sheet metal part.
