Abstract: A heat sink for accumulator cells of an accumulator, the heat sink may include a closed outer shell and two connections. The closed outer shell may delimit an inner volume of the heat sink. The outer shell may include a first wall and a second wall opposite the first wall in a direction of spacing. The first and second walls may be movable relative to one another in the direction of spacing. The two connections may be arranged at a periphery of the outer shell. The connections may be fluidically connected to the inner volume such that a flow path of a cooling fluid extends through the inner volume via the connections.

Abstract: An accumulator temperature control arrangement for a motor vehicle may include an electrical accumulator and a temperature control device for controlling a temperature of the accumulator. The temperature control device may include at least one temperature control element in heat-exchanging contact with an underside of the accumulator. A pressing element may be arranged on a side of the at least one temperature control element facing away from the underside. The pressing element may pretension the at least one temperature control element in a direction of the underside. The arrangement may include at least one bracing element arranged on the underside and faces the pressing element. The pressing element may include a clamping component corresponding to the at least one bracing element and which, together with the at least one bracing element, provide a bracing device that may pretension the pressing element in the direction of the underside.
