The radiator 4 of a vehicle engine 1 is divided into two sections which can be connected by means of a thermostatic valve 7, of which the one section 4b through which cooling fluid always flows, serves both as a heat exchanger and also as a radiator, and the other section 4a serves merely as a radiator. The radiator 4 is arranged between the engine 1 and the passenger compartment 5, so that an inflow pipe 2 and a return flow pipe 3 are necessary for connecting it to the engine. The section 4b of the radiator which serves as a heat exchanger is here in communication via an air conveyance passage 10 with the passenger compartment 5. An air inflow pipe 11, 13, is provided whereby the air flowing in is not only conveyed via the heat exchanger 4b, and according to the position of guide valves 18, 20 conveyed either into the passenger compartments or into the open air as desired, but also conveyed into the passenger compartment 5 bypassing the heat exchanger 4b. The air flowing through the other section 4a can, if necessary, be conveyed with the air flowing through the heat exchanger 4b, through a further air conveyance passage 8 containing a cooling fan 9, into the open air. <IMAGE> |
