PURPOSE:To have a heat exchanger device for a vehicle air conditioner of thermo-medium type integrated in one body and reduced in its size by a method wherein a centrifugal fan, evaporator, radiater and various kinds of dampers are concentrically arranged in a cylindrical or a semi-cylindrical form. CONSTITUTION:A cylindrical evaporator 14 is arranged outside a cylindrical centrifugal fan 11 and a semi-cylindrical radiater 16 is concentrically arranged along the outer circumference of the evaporater as well as a cylindrical damper 19 is rotatably arranged thereon. With this arrangement, the air taken by the fan 11 is subjected to heat exchange with the evaporater 14 to form cooling air, a part of it is adjusted in its flow rate by the damper 17, then passes through the radiater 16 into a cylindrical space 18 and the remaining air flows in X direction into the cylindrical space 18, respectively. Both kinds of air flow kinds of are mixed together in the cylindrical space 18 and then blown out of the blowing ports 25-27. With this arrangement, it is possible to have this device integrated in one body and reduced in its size. |
