Device for controlling the temperature of a battery of electrochemical cells
First Claim
1. A device for controlling the temperature of a battery of cylindrical electrochemical cells disposed side by side, with heat being conveyed by the flow of a heat-conveying fluid, said device comprising:
- a double wall jacket whose section is in the form of circular arcs interconnected at their ends so that the junction points between said arcs are substantially in alignment; and
a plurality of baffles within said double wall jacket and configured to constrain said fluid to flow parallel to said section, alternately in one direction and then in the opposite direction, whereinsaid double wall jacket is disposed against said battery in such a manner that each of said circular arcs is disposed coaxially against one of said cylindrical electrochemical cells.

Abstract
In this device for controlling the temperature of a battery of cylindrically-shaped electrochemical cells placed side by side, heat is conveyed by the flow of a heat-conveying fluid, which flow takes place inside a double wall whose section is in the form of circular arcs interconnected at their ends so that the junction points between the arcs are substantially in alignment. Relief is disposed in a baffle configuration inside the double wall to constrain the fluid to flow parallel to said section, alternately in one direction and then in the opposite direction. The wall is disposed against the battery in such a manner that each of the circular arcs is disposed coaxially against one of the cells.
