Embodiment Construction

[0054] figure 1 A perspective view of the heat exchanger 1 is shown. The heat exchanger 1 is essentially formed from a plurality of tubes 2 which are accommodated at the ends in headers 4 . The header 4 has fluid connections 5 and 6 via which fluid can be introduced into the heat exchanger 1 and removed from the heat exchanger.

[0055] figure 1 The tubes 2 shown in are formed from flat tubes which have two opposite wide sides and two opposite narrow sides. exist figure 1 In , the flat tube 2 is positioned such that the central axis of the tube and the two opposite wide faces are respectively arranged in a plane.

[0056] The headers 4 have holes corresponding to the flat tubes 2 into which the flat tubes can be inserted. The collecting tube 4 is formed by a material strip bent into a U shape, which is closed on the side facing away from the flat tube 2 by a closing device 15 which can be formed, for example, from a profiled wire.

[0057] A cover plate 3 is placed on th...

Abstract

The invention relates to a heat exchanger (1) having a cover plate (3), having a first manifold tube (4), having a second manifold tube (4) and having at least one tube (2), wherein the tube (2) is received at the ends in a respective opening (18) of the first manifold tube (4) and of the second manifold tube (4), wherein the cover plate (3) is in contact with the manifold tubes (4) and in thermal contact with the tube (2), wherein a fixing means is provided by which the cover plate (3) can be fixed to at least one manifold tube (4) and / or to at least one tube (2).

Description

technical field [0001] The invention relates to a heat exchanger with a cover plate, a first header, a second header and at least one tube, wherein the tube is accommodated at the end sides in each of the first header and the second header. corresponding holes in the second header, wherein the cover plate is in contact with the header and in thermal contact with the tubes. Background technique [0002] Today, heat exchangers are used to cool a variety of different components. In particular the cooling of battery components has become increasingly important in recent years. [0003] Batteries generate heat as they are charged and discharged, which either heats the battery or must be dissipated by suitable means. In particular, lithium-ion batteries, which have been popular recently, have a strong temperature dependence. This temperature dependence means, for example, that the aging of the individual battery cells is accelerated due to high temperatures. In addition, exces...
