Heat exchanger and heat exchanger manufacturing method

A heat exchanger comprising:

• a plurality of tube panels including a tube elongated in one direction;
• a header module coupled to an end of the plurality of tube panels;
• and
• a pair of header cases having an open side, providing a space therein, and having the header module inserted in the space such that the tubes communicate with the spaces,
• wherein the header modules is composed of a plurality of header blocks stacked and coupled to each other, and
• an insertion hole in which the tube panel is inserted is formed at each of the plurality of header blocks.

A heat exchanger comprising:

• a plurality of tube panels including a tube elongated in one direction;
• 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 tubes communicate with the spaces,
• wherein the pair of header modules are each composed of a plurality of header blocks stacked and coupled to each other,
• an insertion hole in which the tube panel is inserted is formed at each of the plurality of header blocks,
• the plurality of header blocks each include an upper coupling block and a lower coupling block that form the insertion hole by being combined with each other with the tube panel therebetween,
• a bottom of the upper coupling block is formed in a shape corresponding to a shape of a top of the tube panel and is in contact with the upper panel, and
• a top of the lower panel is formed in a shape corresponding to a shape of a bottom of the tube panel and is in contact with the lower panel.

A method of manufacturing a heat exchanger, the method comprising:

• inserting a tube panel between insertion holes formed in a header block;
• forming a header block by stacking a plurality of header blocks inserted in the tube panel;
• inserting the header block in a space of a header case;
• and
• brazing a heat exchanger including the header module and the header case.
