Heat exchanger structure for a plurality of electrochemical storage cells
View Patent ↗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.
1. A heat exchanger structure comprising:
a plurality of electrochemical storage cells, and
duct components including a plurality of cooling ducts, each of which is defined between respective pairs of material strips arranged parallel to one another over their length, through which thermal control medium flows,
wherein the material strips have wavy profiles adapted to the storage cells,
wherein the storage cells are arranged in a plurality of parallel layers,
wherein the thermal control medium flows through one duct component between a first layer of storage cells and a second layer of storage cells contra-directionally to the thermal control medium which flows through another, adjacent duct component, and
wherein the one duct component engages alternately with storage cells of the first and second layers.
2. The heat exchanger structure according to claim 1 , wherein the thermal control medium flows through the first pair of the duct components, between the first and second layers of storage cells, in two contra-directional directions.
3. The heat exchanger structure according to claim 1 , wherein the one duct component has supporting members arranged at adjacent longitudinal edges of the material strips, and wherein each of the supporting members has a spacer web extending between the material strips.
4. The heat exchanger structure according to claim 3 , wherein at least one of the supporting members has a fixing web which extends perpendicularly to the spacer web and which is adapted to the wavy profiles of the material strips.
5. The heat exchanger structure according to claim 1 , and further comprising a spacer strip extending in the longitudinal direction of the material strips provided between two of the material strips in their middle region.
6. The heat exchanger structure according to claim 1 , wherein two one-piece supporting members are provided which connect each pair of the material strips at adjacent longitudinal edges.
7. The heat exchanger structure according to claim 1 , wherein said duct component is one of a plurality of duct components arranged essentially in one plane and parallel to one another, and wherein adjacent end faces of the duct components are connected to a distributor.
8. The heat exchanger structure according to claim 7 , wherein said distributor is one of at least two distributors which are connected by at least one fixing element running parallel to the duct components.
9. The heat exchanger structure according to claim 1 , wherein the duct components form partially cylindrical segments.
10. The heat exchanger structure according to claim 1 , wherein, as seen in a longitudinal direction, the material strips have alternately contra-directional curvatures.
11. The heat exchanger structure according to claim 1 , wherein, as seen in a longitudinal direction, the material strips have co-directional curvatures.
12. An electrochemical energy store comprising a heat exchanger structure according to claim 1 , wherein the electrochemical energy store is for a vehicle.
13. An electrochemical energy store comprising a heat exchanger structure according to claim 3 , wherein the electrochemical energy store is for a vehicle.
