<P>PROBLEM TO BE SOLVED: To provide a combined heat exchanger compact in size capable of preventing the accumulation of oil mixed in a refrigerant and having high heat exchanging efficiency. Ž<P>SOLUTION: In the combined heat exchanger 1 including a first air-cooled heat exchanger 5 for cooling water for a heating element 3 excluding an engine of an automobile, and a second air-cooled heat exchanger 7 for cooling a refrigerant for air-conditioning a cabin, the first air-cooled heat exchanger 5 has an inflow-side tank 11 into which the cooling water flows, and an outflow-side tank 13 from which the cooling water flows out, flow channel members 15 making the tanks 11, 13 communicated with each other, radiation fins 17 stacked alternately with the flow channel members 15, and a water-cooled heat exchanger 19 for cooling the refrigerant for air-conditioning the cabin. The water-cooled heat exchanger 19 is disposed in of the outflow-side tank 13, and the refrigerant flows in from an upper part of the water-cooled heat exchanger 19, then flows out from a lower part, and flows down to the second air-cooled heat exchanger 7.
