Abstract (en)
[origin: WO2022033994A1] The present invention relates to a temperature-control device for controlling the temperature of a stack-like energy store or converter formed from multiple cells, comprising multiple plate-like heat-conducting elements arranged between the cells, wherein the temperature of the cells is controlled by heat conduction via the plate-like heat-conducting elements, multiple temperature-control ribs which are arranged outside the cells and which serve for changing the flow direction of the temperature-control air flow, wherein the temperature-control ribs are thermally coupled to the heat-conducting elements, and wherein the temperature of the plate-like temperature-control ribs is controlled by means of convection by impingement of a temperature-control air flow and/or by heat conduction via further means, the means for influencing the temperature-control air flow and/or for temperature-control air guidance, which means are configured to change a flow direction and/or a flow speed of the temperature-control air flow, wherein the means are structurally configured and/or arranged such that several of the temperature-control ribs can be impinged on by a temperature-control air volume flow such that a majority of the cells are approximately uniformly heatable or coolable in a cell centre, and wherein the means for influencing the temperature-control air flow and/or for temperature-control air guidance comprise one and preferably two or more of the following components: at least one further temperature-control rib, the shape and/or arrangement of which differs from the shape and/or the arrangement of the other temperature-control ribs, and/or at least one resistance element for changing the temperature-control air flow by locally distributing pressure losses and/or by generating turbulence, and/or at least one temperature-control air guide element for further changing the flow direction and/or the flow speed of the temperature-control air flow in relation to the change of the flow direction and/or the flow speed of the temperature-control air flow by the temperature-control ribs, and/or at least one temperature-control element, which is configured as a heat exchanger.
