Abstract (en)

[origin: EP4047298A1] In a heat exchanger that causes second fluid B to flow between layers of plate fin layered body (2) and carries out heat exchange between first fluid A flowing through plate fin flow path (13) and second fluid B, plate fin (2a) includes header opening (11a) to which first fluid A from a supply pipe is supplied, header flow path (11) formed around header opening (11a), header flow path port (8) that causes header opening (11a) and header flow path (11) to communicate with each other, and plate fin flow path (13) through which the first fluid from header flow path (11) flows, and which carries out heat exchange with the second fluid, and in plate fin layered body (2), inner peripheral sides of header flow paths (11) are continuously joined in a layering direction.
