Embodiment Construction

[0028] The same reference numerals denote the same device components in all figures.

[0029] Figure 1a A first metal sheet 1 and a second metal sheet 2 are shown, wherein a separating medium is applied on at least one first region 3 ( 1 ) of said first metal sheet 1 and on said first metal sheet 1 There is no separating medium on the second zone 3(2). The separating medium is applied to the first metal sheet 1 in a first method step, for example by means of a pressure method.

[0030] exist Figure 1b In this case, the first metal sheet 1 and the second metal sheet 2 are connected to each other in a mechanically non-detachable manner, for example the connection is formed in a second method step by roll bonding.

[0031] Figure 1c shows the passage through the fabricated cooling plate 10 at Figure 1b Sectional view of the plane A-A drawn in , wherein in the third method step, by means of filling the mechanically non-detachable connection of the first metal sheet 1 and t...

Abstract

The invention relates to a cooling plate for an electric energy storage element, said cooling plate comprising at least two non-detachably interconnected metal sheets and at least one plastic covering. The joined metal sheets comprise at least one cooling channel which can be created by separating means.

Description

technical field [0001] The invention relates to a cooling plate for an electrical energy store. Background technique [0002] For example, DE 10 2010 025 656 A1 discloses a modular arrangement for a voltage supply of a motor vehicle, in which a cooling plate in the form of a cooling body is used for cooling the electrochemical storage unit. The cooling body is produced, for example, by means of roll bonding or extrusion, wherein the line course is introduced by laser machining or a flat tube. An insulating layer is provided at the bottom of the housing in order not to reduce the cooling power. [0003] A disadvantage of the known prior art is that only thermal insulation is used between the electrochemical storage unit and the cooling plate and that the cooling plate does not have a separate housing. Contents of the invention [0004] In contrast, the treatment according to the invention with the characterizing features of the independent claim has the advantage that the...
