Embodiment Construction

[0041] pictured in figure 1 The accumulator 10 has a plurality of energy storage elements 12 and a heat exchanger 14 resting on the energy storage elements 12 to control the temperature of the energy storage elements 12 . To this end, the heat exchanger 14 has a heat exchange surface 16, through which the heat exchanger 14 rests on the energy storage element 12, and a fluid channel 18, through which a fluid 20 can be led through the heat exchanger 14 to control its temperature, The temperature of the energy storage element 12 is thus controlled.

[0042] It should be understood that the heat exchanger 14 can also be used to control the temperature of other components, such as power electronics. In the following, only the temperature control of the energy storage element is illustrated by way of example.

[0043] For example, the energy store 10 is used in a motor vehicle, in particular a hybrid motor vehicle or an electric vehicle. To this end, the energy store 10 has an en...

Abstract

The invention relates to a heat exchanger for controlling the temperature of energy storage elements (12) of an energy store (10) and / or of power electronics, for example of battery cells, having a heat exchange surface (16) which is placed on the energy store (10). Essential to the invention is the fact that the heat exchanger surface (16) is partially coated with a layer (29) comprising a heat-conducting material, and that the heat exchange surface (16) has contact regions (30) which are provided with the heat-conducting layer (29), and insulating regions (32) which are not provided with the heat-conducting layer (29). The invention further relates to an energy store and to the production thereof having energy storage elements (12) and at least one such heat exchanger (14), which rests on the energy storage elements (12) in order to control the temperature of the energy storage elements (12). Essential to the invention is the fact that a contact area between the energy storage elements (12) and the heat exchanger (14) is formed by the heat-conducting layer (29) applied to the heat exchanger (14).

Description

technical field [0001] The invention relates to a heat exchanger for controlling the temperature of an energy storage element such as an energy store and / or a power electronic component, having a heat exchange surface placed on the energy store. The invention further relates to an energy store with at least one such heat exchanger, and to the production of such a heat exchanger. Background technique [0002] In modern hybrid and electric vehicles, energy stores such as lithium-ion batteries are used. In order to guarantee optimal performance and a long service life of the energy storage, effective thermal management is necessary, which enables the operation of the energy storage elements of the energy storage, such as battery cells, in a specific temperature window. Under load, the energy storage elements must be actively and uniformly cooled, and in the cold season they must be heated accordingly. For this, a reliable contact between the energy storage element and the hea...
