Generally, the heat exchanger is provided with a passage portion through which the heat exchange medium can flow, and is designed to perform heat exchange with the outside air while the heat exchange medium flows through the passage portion. The type of the heat exchange medium and the heat exchange medium A variety of methods have been developed depending on internal pressures such as a fin tube type, a serpentine type, a drawn cup type, and a parallel flow type. have

In such a heat exchanger, a heat exchanger core (generally referred to as a Heater Core, an Evap Core, a Radiator Core, or an Inter Cooler Core) in which heat exchange is mainly performed is composed of a header and a radiating fin and a tube which are stacked and fixed between the header.

The parallel flow type heat exchanger of the heat exchangers includes a pair of header tanks arranged side by side, a plurality of tubes disposed side by side between the header tanks and having both ends thereof inserted and fixed in the tube insertion holes formed in the header tank, And a heat-dissipating fin provided between the tubes, the heat-exchanging medium having a large heat-transfer area for effectively exchanging heat with the outside.

In the heat exchangers described above, a corrugated type heat dissipating fin is used as a conventional heat dissipating fin for widening the heat dissipating area. The corrugated heat-dissipating fin has a structure in which a plate material is wavy and wrinkled, and a louver is formed on the surface thereof.

Such a conventional radiating fin improves the heat radiation performance with air, increases the heat radiation area by adjusting the bending pitch of the radiating fin in order to reduce the discharge pressure of the compressor, and adjusts the louver angle or louver pitch of the radiating fin. And the like.

However, as described above, the radiating fin formed in a corrugated shape has curved surfaces at the apexes of the bone and the mountain, has an inflection point, and is placed between the tubes so that the mountains and the bone sites of the radiating fins come into line contact during brazing, Even if it is bonded to the tube by the clad layer, there is a problem that the bonding area is relatively narrow and the heat transfer efficiency can not be improved.

Korean Patent No. 363318 discloses a method and structure for joining a radiating fin and a tube of a heat exchanger, and Korean Patent No. 574337 discloses a method for manufacturing a radiating fin for a heat exchanger. No. 0659568 discloses a heat exchanger pin, and Korean Patent Publication No. 2003-0020563 discloses a louver pin for a heat exchanger.
