Abstract
A heat exchanger structure for a plurality of electrochemical storage cells has at least one duct component through which thermal control medium flows. The duct component has two material strips which are arranged parallel to one another and between which a heat exchanger duct is formed. The material strips have shaped portions adapted to the storage cells. The heat exchanger structure is useable, for example, for a motor vehicle battery.
Claims15
Heat exchanger structure for a plurality of electrochemical storage cells (10), with at least one duct component (20;
- 72, 78, 84;
- 102, 104, 106) through which thermal control medium flows, and in which the duct component (20;
- 72, 78, 84;
- 102, 104, 106) has shaped portions (50, 52) adapted to the storage cells (10),
- characterized in that
- the storage cells (10) are arranged in a plurality of parallel layers (12, 14;
- 74, 76, 86;
- 90, 92, 94, 96), the thermal control medium in the respective duct component (20;
- 72;
- 100) between a first and a second layer (12, 14;
- 74, 76;
- 92, 94) of storage cells (10) flowing contra-directionally to the thermal control medium in the respective duct component (84;
- 102) between the second and a third layer (76, 86;
- 94, 96) of storage cells (10) and/or in a duct component (20) closing off the second layer (14).
Heat exchanger structure according to one of the preceding claims, characterized in that two duct components (20;
- 72, 78, 84;
- 102, 104, 106) for receiving at least one storage cell (10) are arranged opposite one another and in such a way that shaped portions extending in contra-directional directions are located opposite one another.
Heat exchanger structure according to one of the preceding claims, characterized in that a plurality of duct components (20;
- 72, 78, 84;
- 102, 104, 106) are arranged essentially in one plane (118) and parallel to one another, and adjacent end faces of the duct components (20;
- 72, 78, 84;
- 102, 104, 106) are connected to a distributor (16, 18).
Use of a heat exchanger structure according to one of the preceding claims for an electrochemical energy store, in particular for a vehicle, with a plurality of storage cells (10).
