Problems solved by technology

However, due to the large number of cooling fins and their arrangement, such a cooling device requires on the one hand a high production or assembly effort and on the other hand leads to a complex and large battery module.
In addition, leaks may occur due to the multiple connection points between the housing of the cooling fins and the collector, which may cause damage to the battery cells

Embodiment Construction

[0022] Refer below Figure 1 to Figure 3 The cooling and / or heating device 1 according to a preferred first exemplary embodiment of the invention will be described in detail.

[0023] as available from Figure 1 to Figure 3 As can be seen in the figure, the cooling and / or heating device 1 according to the invention has a metal base body 2 with a plurality of channels 20 through which the coolant and / or heating medium flows, a first collector made of plastic container 3 and a second collector 4 made of plastic.

[0024] The base body 2 is designed as a continuously cast profile made of aluminum and is inserted into the first collector 3 and the second collector 4 . Furthermore, the base body 2 is plate-shaped and has a first flat side 23 and a second flat side 24 ( image 3 ).

[0025] The channel 20 extends straight from the first collector 3 to the second collector 4 and has a substantially rectangular cross-section. Furthermore, the first collector 3 is arranged at the fi...

Abstract

The present invention relates to a cooling and / or heating apparatus of a battery module. The apparatus comprises at least one metal base body (2) having a plurality of channels (20), through which a cooling and / or heating agent passes, a first collectors (3) made of plastic, and a second collector (4) made of plastic. According to the invention, the channel (20) extends from the first collector (2) to the second collector (3). According to the invention, the first collector (3) is arranged at a first end (21) of the channel (20) and is connected to the base body (2) by means of a first connecting device (5), the second collector (3 ) is disposed at a second end (22) of the channel (20) and connected to the base body (2) by means of a second connecting device (6). Furthermore, the present invention relates to the battery module comprising a plurality of battery cells (90) and the cooling and / or heating apparatus (1) according to the invention.

Description

technical field [0001] The invention relates to a cooling and / or heating device, in particular for a battery module of an electric vehicle. Furthermore, the invention also relates to a battery module comprising such a cooling and / or heating device. Background technique [0002] Such a cooling device is known, for example, from US 2011 / 0027640 A1. This is a cooling device for cooling a battery module, which has a plurality of cooling fins. Each cooling fin has a housing with cooling channels through which the coolant flows and two collectors made of metal for supplying and discharging the coolant, the housing being connected to the connected to the collector. Furthermore, each cooling fin is arranged between two consecutive battery cells of the battery module. However, due to the large number of cooling fins and their arrangement, such cooling devices on the one hand require greater manufacturing or assembly effort and on the other hand lead to complex and larger battery ...
