Abstract:
1. A power supply device for a motor vehicle, comprising: one or more storage cell modules, each storage cell module comprising at least one of one or more electrochemical storage cells and double layer capacitors arranged next to and/or on top of one another and coupled to one or more thermally conducting and mechanically rigid profiles, wherein the thermally conductive and mechanically rigid profiles comprise aluminum; a cooler block comprising a holder for the storage cell modules; and a heat dissipating structure for dissipating heat emitted by the storage cell modules, the heat dissipating structure being arranged on at least one side of the holder; wherein the cooler block further comprises a clamping device generating a predefined force by which the heat dissipating structure is pressable against the one or more thermally conducting and mechanically rigid profiles, and wherein the clamping device comprises at least one clamping plate having a curvature generating a spring force oriented opposite to the curvature when the clamping plate is in a clamped, planar position, whereby the clamping plate is, by virtue of the spring force generated by the curvature, presses the heat dissipating structure against the one or more thermally conducting and mechanically rigid profiles, said profiles transfer heat from the at least one of one or more electrochemical storage cells and double layer capacitors to the heat dissipating structure.
