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

A heat exchanger may include a heat exchange surface partially coated with a heat-conducting layer. The heat exchange surface may include a plurality of contact regions coated with the heat-conducting layer and a plurality of insulating regions that are not coated with the heat-conducting layer. The heat exchange surface may further include a degree of coverage of the heat-conducting layer that varies to compensate at least one of at least one hot spot and at least one cold spot. The at least one hot spot and the at least one cold spot may be included within at least one of the heat exchange surface and a plurality of energy storage elements of an energy store that contacts the heat exchange surface.

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...
