Thermal regulation device for cooling electrical energy storage means

A method for assembling an electrical energy storage device for an electric or hybrid vehicle, including several assemblies of electrical energy storage members and several thermal regulation devices, wherein each thermal regulation device includes a tube that is configured to be in contact with the electrical energy storage members and that includes at least one circulation channel for circulating a heat transfer fluid, a collecting tank that is disposed at one end of the tube and that includes collecting chambers that fluidically communicate with the at least one circulation channel of the tube, and at least two connecting sleeves disposed on either side of the collecting tank and configured to communicate with the same collecting chamber, the at least two connecting sleeves having shapes that are distinct from one another, with each thermal regulation device being arranged between two assemblies of electrical energy storage members, two adjacent thermal regulation devices being configured to be connected in a leak-tight manner by direct cooperation of a connecting sleeve of a first type, respectively of a second type, of a first thermal regulation device, equipped with a sealing gasket, with a connecting sleeve of a second type, respectively of a first type, of a second thermal regulation device, the method comprising:

• placing electrical energy storage members are placed against a tube of a first thermal regulation device,
• placing a tube of a second thermal regulation device against the previously placed electrical energy storage members, by inserting the connecting sleeves that are associated with this tube of the second device and that are disposed on one side of the collecting tank of the second device directly into the connecting sleeves that are associated with the tube of the first device and that are disposed on one side of the collecting tank of the first device.
