Abstract

A heat exchanger includes a heat exchange core, an introduction tank for introducing a heat transfer medium into the heat exchange core, and a discharge tank for receiving the heat transfer medium discharged from the heat exchange core. Materials used to form the introduction tank and the discharge tank are different from each other. The properties desired for the respective tanks may be attained, and while unnecessary increases in the costs for manufacturing the heat exchanger is may be reduced or avoided, the performance of the heat exchanger may be improved.

Claims (13)

1. A heat exchanger comprising:

a heat exchange core;

an introduction tank attached to said heat exchange core for introducing a heat transfer medium into said heat exchange core; and

a discharge tank attached to said heat exchange core for receiving said heat transfer medium discharged from said heat exchange core,

wherein said introduction tank is formed of a first material, said discharge tank is formed of a second material, a heat conductivity of the first material is greater than a heat conductivity of the second material, and a specific gravity of the first material is less than a specific gravity of the second material.

2. The heat exchanger of claim 1 , wherein said introduction tank and said discharge tank are attached to said heat exchange core at ends of said heat exchange core opposite to each other.

3. The heat exchanger of claim 1 , wherein at least one of said introduction tank and said discharge tank is made of a resin.

4. The heat exchanger of claim 3 , wherein said resin is a polyamide.

5. The heat exchanger of claim 4 , wherein said polyamide is an aliphatic polyamide.

6. The heat exchanger of claim 3 , wherein said resin further comprises an inorganic material.

7. The heat exchanger of claim 6 , wherein said inorganic material is a glass fiber.

8. The heat exchanger of claim 1 , wherein said heat exchange core comprises a plurality of heat transfer tubes and fins, which are stacked alternately.

9. The heat exchanger of claim 1 , wherein said heat exchanger is an intercooler, and said heat transfer medium is charged gas from a turbo-charger or a supercharger.
