A device for thermal regulation, in particular for cooling, for an electrical component that is liable to release heat during its operation, in particular for an electrical energy storage module. The device includes a first plate and a second plate, which is assembled with the first plate, each being delimited by edges, in order to form together a plurality of circulation channels for a heat-exchange fluid, in particular a refrigerant fluid. The plurality of channels define a channel zone, and the two plates are assembled by laser welding, preferably transmission laser welding, at the channel zone. The device includes an additional joining means, which is different than the transmission laser weld and which connects the edges of at least one plate to the other plate.
