1. A housing element of a battery, wherein
the housing element (1) is configured to be connected to another housing element so as to form a common interior space designed for receiving a plurality of battery cells of a battery module,
wherein the housing element (1) forms a temperature-control structure (2) on a first side (10) and a covering element (3) is connected to the housing element (1) in such a way that the covering element (3) delimits a flow duct (4), through which temperature-control fluid can flow, in a fluid-tight manner and the temperature-control structure (2) is configured such that the temperature-control fluid flows around it
wherein the temperature-control structure (2) is configured in such a way that a flow-guiding element (21), which delimits the flow duct (4) for guiding the temperature-control fluid, rises from the first side (10),
wherein a plurality of vortex elements (22), which are arranged in such a way that a turbulent flow of temperature-control fluid flowing in the flow duct (4) is created, rise in the flow duct (4),
wherein the flow-guiding element (21) is configured, with a greater height than respective vortex elements (22) of the plurality of vortex elements (22), so that the covering element (3) is arranged on the flow-guiding element (21) at a minimum distance of 0.5 mm from the plurality of vortex elements (22), and
wherein the plurality of vortex elements (22) are circular and have a height (73) of between 11.5 mm and 14.5 mm.
