Battery housing, battery and method for manufacturing a battery

A battery housing having a housing interior for an arrangement of a plurality of battery cells, and a housing unit which at least partially surrounds the housing interior and has a duct system with a plurality of channels for guiding a fluid for temperature control of the housing interior,

• wherein the housing unit comprises at least a first housing side with a first fluid access point for external access to the duct system,
• wherein,
• the channels extend at least partially along the first housing side in different directions and the duct system comprises a guide structure for a common fluid communication of the channels with the first fluid access point,
• wherein the guide structure is formed by a star-shaped course of more than two restriction elements of the channels, wherein the guide structure has a distribution point at which the more than two restriction elements converge on the first housing side, wherein at least two of the restriction elements at the distribution point form an angle with each other, thereby forming a narrowing channel opening for hydrodynamically directing a fluid flow of the fluid.
