Abstract:
1. A composite heat exchanger comprising: an air cooled condenser having a pair of tanks and a core part arranged between the tanks thereof; a sub-radiator having a pair of tanks and a core part that is arranged between the tanks thereof and on a same plane as a plane of the core part of the air cooled condenser, the core part of the sub-radiator being formed with the core part of the air cooled condenser as one unit; and a main radiator having a pair of tanks and a core part that is arranged between the tanks thereof, wherein one of the tanks of the sub-radiator is formed in a state where the one of the tanks is communicated with a downstream side tank of the tanks of the main radiator such that the one of the tanks of the sub-radiator is provided to project forward from the downstream side tank of the main radiator, having a rectangular box shape, so that the one of the tanks of the sub-radiator and the downstream side tank of the main radiator are formed as one unit, another tank of the tanks of the sub-radiator is apart from an upstream side tank of the main radiator, one of the tanks of the sub-radiator contains a water cooled condenser, and a part of a flowing medium that is cooled down by the main radiator is introduced into the sub-radiator to cool a flowing medium of the water cooled condenser, and the flowing medium that is cooled by the water cooled condenser is introduced into the air cooled condenser to be cooled.
