  • brackets 112 , 114 are then also bent, that is, so that they are arranged essentially parallel to the side walls 22 , 24 and thus form regions for a solder connection with the side walls 2 , 24 .
  • triangular recesses are given in the regions 116 , 118 that are, for example, punched and that allow, in certain applications, simplified bending.
  • FIG. 6 shows a cutout shown in perspective for an example coolant casing 10 or 12 according to the invention, wherein it is to be noted that the structure according to FIG. 6 could also be given in the embodiment according to FIGS. 1 a to 3 k.
  • FIG. 6 shows a perspective view of an alternative first, one-piece unit 16 b that also has the base 20 , the side parts 22 , 24 , and also the end parts 26 , 28 (not shown), but differs in the production of the first one-piece unit 16 or 16 a in the structure according to FIGS. 4 and 5 .
  • the cover 18 is inserted into this casing or unit 16 b and soldered to this casing or unit, in particular, by means of solder-plating.
  • the casing 10 , 12 is made from metal, in particular, from aluminum.
  • the cover 101 has edge regions 106 , 107 placed on its four edges, wherein these edge regions contact the insides and optionally the upper narrow sides of the side walls 104 . 105 and can be connected to these sides in a sealing way.
  • edge regions 106 On the long sides of the cover 101 there are edge regions 106 that are positioned essentially at a right angle to the plane of the cover and that have flaps 108 that are bent into an approximately U-shaped form such that they grip over the upper end regions or narrow sides of the side walls 104 .
  • On the short sides of the cover 101 there are additional assemblies or edge regions 107 that have a structure rising at an angle in a first region and that have, in another region, an essentially U-shaped form or flaps that grip over the end region of the side wall 105 . In this way, the upright region 107 contacts the side wall 105 on the outside of the side wall with its inside.
  • FIGS. 8 a to 8 d show another embodiment example of a casing-cover connection in which the casing 200 is connected to the cover 201 .
  • the casing 200 here has a tube base 202 in which there are openings 203 or passages for holding tubes. Furthermore, the casing 200 has side walls 204 , 205 that are bent upward essentially at a right angle starting from the tube base and that are positioned upright. By means of the side walls 204 , 205 , the casing 200 forms a nearly right-angle casing 200 that is essentially open on one side with four side walls 204 , 205 that contact each other on their narrow sides or narrow-side end regions and that are connected in a sealed way, for example, they are soldered to each other.
  • the cover 201 there are assemblies or edge regions 207 that have an essentially U-shaped form or corresponding U-shaped flaps 209 that grip over the end region of the side wall 205 .
  • the one or more upright regions 207 or the flaps 209 contact a region of the side wall 205 on both sides with their two inner surfaces on the corresponding outer surface of the side wall 205 .
  • the joint surfaces are also significantly improved because the joint surfaces advantageously contact each other essentially without gaps.
  • edge 305 of the cover 301 is beveled at its lower region connecting to the base of the cover (see 310 ), so that this bevel is used as insertion beveling 310 for the assembly of the cover 301 in the casing 300 .
  • FIGS. 13 a to 13 c and 14 a to 14 c show another embodiment of a casing 400 with a cover 401 .
  • the cover 401 is deep-drawn and has an essentially flat, central region 402 but that could definitely have beads 403 for reinforcement.
  • the cover 401 has connection possibilities with openings 404 for feeding and/or discharging a fluid and advantageously optionally for the attachment or arrangement of connection flanges or connection tubes 405 .
  • the cover 401 has connection possibilities for holding elements 406 that can be connected to the cover. These can be, for example, riveted, soldered, or mechanically joined to the cover.
  • the corner region 410 of the cover 401 and the casing has a rounded structure, so that the question of the exact fit of the cover 401 and casing 400 in the corner region could be more easily guaranteed.
  • a receptacle 411 for a separating wall that is arranged within the casing and that could be inserted, if needed, so that it could separate the casing into two regions. If the separating wall is not needed, then it could also be left out.
  • the casing 400 has four walls 413 , 414 , 415 , and 416 , wherein, of these four, two are short end walls 415 and 416 and two are long side walls 413 and 414 . These are advantageously deep-drawn with the base 412 of the casing 400 in one piece. In the base 412 there are openings or passages for holding tubes. Furthermore, in the casing 400 there are side receptacles 417 for a separating wall, wherein these side receptacles interact with the receptacles in the cover, in order to hold or fix, if needed, a separating wall.
  • FIG. 15 shows a heat exchanger 500 that has a network on parallel tubes 501 and ribs 502 advantageously arranged in between.
  • the tubes 501 are inserted in their end regions into casings 503 , 504 in a sealed way, wherein the casings 503 , 504 have openings or passages in a tube base for this purpose.
  • the casings have the structure of the cover and casing shown in FIGS. 13 and 14 , wherein connection ports 505 are provided on a casing for feeding and discharging a fluid.
  • holding means 506 can be recognized.
