Claim 0:
1. A heat exchanger comprising:
a plurality of tube panels including a plurality of tubes elongated in one direction and a plurality of fins;
a pair of header modules coupled to both ends of the plurality of tube panels; and
a pair of header cases having an open side, providing a space therein, and having the pair of header modules inserted in the spaces, respectively, such that the plurality of tubes communicate with the spaces, wherein each header case has the open side, wherein the pair of header modules each includes a plurality of header blocks stacked and coupled to each other, and at least one insertion hole in which the tube panel is inserted is formed at each of the plurality of header blocks, wherein
each header block of the plurality of header blocks includes an upper coupling block and a lower coupling block that forms the at least one insertion hole by being combined with each other with the tube panel therebetween, wherein the tube panel is configured such that a fin of the plurality of fins is formed by a flat portion and a recession is formed by coupling an upper panel and a lower panel, each of which has the flat portion and a recession, wherein a bottom of the upper coupling block is formed in a shape corresponding to a shape of the upper panel and is in contact with the upper panel, and wherein a top of the lower coupling block is formed in a shape corresponding to a shape of the lower panel and is in contact with the lower panel.
