The invention relates to a plate-type heat exchanger (30) for a vehicle for cooling a cooling fluid by means of a coolant, having a plurality of heat exchanger plates (40) which are stacked one on top of the other. Coolant chambers (44) and cooling fluid chambers (46), which each have an inflow (48, 52) and an outflow (50, 4) for the coolant and/or the cooling fluid are formed between adjacent heat exchanger plates (40), and wherein the coolant and/or cooling fluid chambers (44, 46) are embodied in their entirety as U-shaped flow ducts (64, 68), wherein the assigned inflow (48, 52) is arranged at the end of the first limb, and the assigned outflow(50, 54) is arranged at the end of the second limb, of the U-shaped flow duct (64, 68). The invention also relates to an air-conditioning circuit (10) for a vehicle, in particular for a vehicle having an electric motor, with a primary circuit (12) for a coolant and a secondary circuit (14) for a cooling fluid, wherein the primary circuit (12) and the secondary circuit (14) are coupled via a plate-type heat exchanger (30). |
