Patent ID: 7669437

Claim:
A heat exchanger module comprising: a condenser for cooling and condensing a refrigerant; a gas-liquid separator which separates the refrigerant from the condenser into gas refrigerant and liquid refrigerant; a sub-cooler for cooling the separated liquid refrigerant flowing from the gas-liquid separator; and a heat exchanger for cooling a fluid different from the refrigerant, wherein: the condenser, the sub-cooler and the heat exchanger are stacked together in a stacked direction with respect to a flow direction of air passing through the condenser; and the condenser is located between the sub-cooler and the heat exchanger in the stacked direction; wherein the condenser, the sub-cooler and the heat exchanger are constructed with an integrated unit that includes: a plurality of first tubes arranged in parallel through which refrigerant flows in a tube longitudinal direction, a plurality of second tubes arranged in parallel through which the fluid flows in the tube longitudinal direction, a header tank extending in a direction perpendicular to the tube longitudinal direction to communicate with the first tubes and the second tubes, and a partition member located in the header tank to partition an interior of the header tank into a first tank space communicating with the first tubes, and a second tank space communicating with the second tubes.
