Abstract
The present invention relates to a heat exchanger wherein a flat joining portion is formed on a tank, whereby a flange can be easily coupled to the inlet and outlet of the tank, the process of manufacturing the tank can be simplified, and the degree of shape freedom of the tank can be ensured.
Claims23
A heat exchanger comprising:
- a core including a plurality of tubes in which a heat exchange medium flows;
- a pair of headers provided on both sides of the core, each having a tube insertion hole and fluidly coupled to the plurality of tubes through the tube insertion hole;
- and
- a pair of tanks coupled to the pair of headers, respectively, to form a pair of header tanks,
- wherein one side tank of the pair of header tanks includes an inlet through which the heat exchange medium flows into the one side tank and an outlet through which the heat exchange medium is discharged from the one side tank, and
- at least one of the inlet and the outlet has a flat joining portion in which an outer wall of the one side tank has a flat shape.

A method for manufacturing a heat exchanger including a core including a plurality of tubes in which a heat exchange medium flows;
- a pair of headers provided on both sides of the core, each having a tube insertion hole and fluidly coupled to the plurality of tubes through the tube insertion hole;
- a pair of tanks coupled to the pair of headers, respectively, to form a pair of header tanks;
- an inlet provided on one side tank among the pair of header tanks to allow the heat exchange medium to flow into the one side tank therethrough and an outlet provided on one side tank among the pair of header tanks to allow the heat exchange medium to be discharged from the one side tank therethrough, at least one of the inlet and the outlet having a flat joining portion in which an outer wall of the one side tank has a flat shape;
- and a flange coupled to the inlet or the outlet in which the flat joining portion is formed, the flange including a tank joining portion joined to the inlet or the outlet, the tank joining portion having a flat shape corresponding to the flat joining portion, the method comprising:
- S10) coupling the flange to at least one of the inlet and the outlet;
- and
- S20) melting and coupling the flange to the one side tank through brazing.
