Embodiment Construction

[0040] figure 1 A transverse sectional view of a tube floor 1 known from the prior art is shown. The tube bottom 1 has a plurality of openings 3 which are arranged in the planar bottom region 2 . These openings 3 are each surrounded by flanges 4 . On the right and left of the opening 3 are formed U-shaped recesses 5 which are formed substantially between the upstanding edge region 6 and an inner wall 7 extending parallel to this edge region. The bases of the U-shaped grooves 5 are each closed by groove bases 8 . The tube can be inserted into the opening 3 along the direction 9 .

[0041] figure 2 A sectional view of an alternatively designed tube base 10 is shown, which has a different geometry, in particular for the U-shaped groove 14 . In particular, the transition of the bead 13 to the U-shaped recess 14 is designed differently.

[0042] The tube base 10 has a base region 11 in which a plurality of openings 12 are formed, which are surrounded by a flange-like bead. ...

Abstract

The invention relates to a tube bottom (80) for a heat exchanger, with a bottom region (81) having slot-type openings (82), wherein the slot-type openings (82) are rimmed by eyelets (83) and the tube bottom (80) has an attached rim region (85), wherein there is formed between the eyelets (83) and the attached rim region (85) a U-shaped trough (84) as receiving region for the foot of a box-like cover, wherein the U-shaped trough (84) consists of an inner first wall (87), the attached rim region (85) and a second wall forming the trough bottom (94), wherein the inner first wall (87) has at least one hump-like raised portion (88) in the continuation of an eyelet (83) on the side (95) oriented toward the U-shaped trough (84), which bounds the breadth of the U-shaped trough (84) between the attached rim region (85) and the first wall (87) and extends from the trough bottom (94) to that end region of the eyelet (83) oriented toward the U-shaped trough (84), wherein a depression (90) is formed in the hump-like raised portion (88), wherein forming the depression (90) produces a displacement of material toward that side (96) of the first wall (87) that is oriented away from the U-shaped trough (84). The invention also relates to a heat exchanger.

Description

technical field [0001] The invention relates to a tube bottom for a heat exchanger, which comprises a bottom region with a plurality of slot-shaped openings, wherein the slot-shaped openings are surrounded by a bead and the tube bottom has an upstanding edge region, wherein A U-shaped groove is formed between the flange and the upstanding edge region as a receiving region for the base of the box-shaped lid, wherein the U-shaped groove is formed by the inner first wall, the upstanding edge region and the groove The second wall portion of the bottom constitutes. Furthermore, the invention also relates to a heat exchanger. Background technique [0002] The coolant cooler can have a plurality of tubes through which a medium can flow and at the same time around which a medium can flow. In a known construction, the tubes are accommodated at the ends in a tube base. These tube bases have a number of openings corresponding to the number of tubes, wherein each tube is inserted int...
