Claim 0:
1. A battery module unit for a motor vehicle battery, said battery module unit comprising:
(i) a housing,
(ii) a plurality of battery cells positioned in the housing and which are configured as pouch cells, and
(iii) a base plate in thermal contact with the battery cells, said base plate comprising a cooling segment for controlling the temperature of a battery module of a motor vehicle battery, said cooling segment comprising:
(a) an inflow channel through which a cooling fluid can be fed,
(b) an outflow channel configured for discharging the cooling fluid, and which is spaced apart from the inflow channel, and
(c) a plurality of cooling channels which communicate with the inflow channel and the outflow channel,
wherein each respective cooling channel has (i) a first channel portion which is fluidly connected directly to the inflow channel and which partially extends toward the outflow channel, (ii) a second channel portion which is fluidly connected directly to the first channel portion and which extends away from the outflow channel and at least partially toward the inflow channel, and (iii) a final portion which is fluidly connected either directly or indirectly to the second channel portion and is fluidly connected directly to the outflow channel,
wherein the plurality of cooling channels are arranged in at least two columns and at least two rows,
wherein the first channel portion of the plurality of cooling channels are all directly fluidly connected to the same inflow channel, and
wherein the inflow channel extends between the at least two columns of cooling channels and fluidly and directly intersects the at least two rows of cooling channels, and the inflow channel is directly and separately fluidly connected to each of the first channel portions of the plurality of cooling channels that are arranged in at least two columns and at least two rows.
