Thermal regulation device for cooling electrical energy storage members

A thermal regulation device for cooling and/or heating components the operation of which is sensitive to temperature, these components being intended in particular for energy storage and possibly being battery cells of electrical energy storage members, comprising:

• a distribution tank configured to be connected to a fluid inlet pipe and to a fluid outlet pipe, the distribution tank comprising a fluid intake chamber adapted to be served by the inlet pipe and a fluid return chamber adapted to be served by the outlet pipe,
• a tube with two fluid circulation assemblies rigidly secured by a bridge of material, each assembly comprising a plurality of circulation channels along which the heat transfer fluid circulates from one longitudinal end of the tube to the other, a first fluid circulation assembly in communication with the intake chamber and a second fluid circulation assembly in communication with the return chamber, the fluid circulation assemblies having, in cross section of the tube, long edges inscribed on two parallel straight lines, the bridge of material interrupting the continuity of material on at least one of the parallel straight lines forming at least one longitudinal absence of material on the tube,
• the thermal regulation device being wherein the distribution tank comprises at least one rib separating the intake chamber from the return chamber, a part of the rib being housed in the absence of material at a junction zone of the tube with respect to the distribution tank and in that the bridge of material comprises a notch opening out on an end face of the tube, the distribution tank comprising a longitudinal bulge forming a protrusion from the rib and housed at least partially in the notch.
