In a coolant condenser assembly for a motor vehicle air conditioning system, comprising cooling pipes for conducting a coolant through, two collecting pipes for fluidically connecting the cooling pipes, a collecting container with an upper cover wall and a lower bottom wall and a side wall as well as with an inlet opening for conducting the coolant into the collecting container and an outlet opening for conducting the coolant out of the collecting container, with the result that through the inlet and outlet openings the collecting container is fluidically connected to the collecting pipe and/or the cooling pipes, the collecting container comprises an outlet chamber and a riser pipe, and the outlet opening opens into the outlet chamber, and the outlet chamber is connected to the riser pipe and a storage chamber for the coolant is formed within the collecting container and outside the outlet chamber and outside the riser pipe, the collecting container preferably has an inlet chamber and a downpipe, and the inlet opening opens into the inlet chamber and the inlet chamber is connected to the downpipe and the storage chamber is formed outside the inlet chamber and outside the downpipe, the cooling pipes have a superheating region for cooling the vaporous coolant, a condensation region for condensing the coolant and a supercooling region for cooling the liquid coolant, wherein the supercooling region is formed above the superheating region and above the condensation region, the intention is that little coolant will be present in flow spaces in the collecting container. This object is achieved in that the height of the storage chamber is greater than the distance between the lower floor wall and the inlet and/or outlet openings.
