Abstract
The present invention relates to a heat exchanger including a header having a plurality of groove portions concavely recessed from an end of the header between a plurality of bent tabs spaced apart from one another along a periphery of the header, and a tank having a lower end inserted into the header, the tank being coupled by bending the bent tabs inward and coupled to the header to define a flow space for a heat exchange medium, in which first groove portions, which each have a larger depth than the groove portions, are formed in the header to easily allow thermal deformation caused by a temperature difference, thereby reducing thermal stress and preventing a leak of the heat exchange medium.
Claims19
A heat exchanger comprising:
- a pair of header tanks disposed to be spaced apart from one another;
- and
- a plurality of tubes each having two opposite ends connected to the pair of header tanks,
- wherein the pair of header tanks each comprises:
- a header comprising a plurality of bent tabs spaced apart from one another along a periphery of the header, the header having a plurality of groove portions formed between the plurality of bent tabs and concavely recessed from an end of the header;
- and
- a tank having a lower end inserted into the header and coupled as the bent tabs are bent inward, the tank being coupled to the header to define a flow space for a heat exchange medium, and
- wherein first groove portions, which have a larger depth than the groove portion, are formed in the header of each of the pair of header tanks.
