Abstract
A heat transmission unit includes a channel conducting a coolant, and a channel conducting a fluid to be cooled. The two channels are separated from each other by a wall provided with ribs extending therefrom into at least one of the two channels. The channel conducting the fluid to be cooled includes a fluid inlet and a fluid outlet. The channel is separated by a partition wall, arranged in flow direction, into a first and a second partial channel having a first partial inlet for fluid and a second partial inlet for fluid, and a first partial outlet for fluid and a second partial outlet for fluid. At least the first partial inlet for fluid is adapted to be shut off by a first shut-off device.
