Abstract: The invention relates to a temperature control device, in particular a cooling device, for an electrical component that is capable of releasing heat during its operation, in particular for an electrical energy storage module. The device has a first outer plate and a second outer plate, as well as a central member arranged between the two outer plates. The central member includes reliefs arranged in order to form, with the outer plates, at least two layers of circulation channels for a heat-transfer fluid. The layers are located on either side of the central member and have the same heat-transfer fluid circulation direction.
