A cooling segment for controlling the temperature of a battery module of a motor vehicle battery. The cooling segment includes an inflow channel for feeding of a cooling fluid, an outflow channel for discharge of the cooling fluid, which runs spaced apart from the inflow channel, and a plurality of cooling channels which communicate with the inflow channel and the outflow channel. The respective cooling channel has a first channel portion which is connected directly to the inflow channel and which partially runs to the outflow channel. A second channel portion is connected directly to the first channel portion and runs away from the outflow channel and partially toward the inflow channel. A final portion is connected directly or indirectly to the second channel portion and connected directly to the outflow channel.
