PROBLEM TO BE SOLVED: To provide a heat exchanger in which breakage of a porous member when particles are charged into the heat exchanger can be prevented.SOLUTION: A heat exchanger 1 includes: a core 2 constituted by alternately laminating corrugated fins and plates, and having a first inlet 5a and a first outlet 5b for first fluid, and a second inlet and a second outlet for second fluid; and a pair of headers 3A, 3B each including domes 31, particle charging pipes 32, and first fluid pipes 34. A tip of the particle charging pipe 32 of each header is closed by a cap 33, and a supporting member 7 detachable to the header, is disposed in the particle charging pipe 32. The supporting member 7 has an opening 70 for communicating the inside of the dome 31 with a chamber 35 between the supporting member and the cap 33. A porous member 8 is fitted to the supporting member 7 so as to cover the opening 70, and particles 50 are filled into the dome 31 of each header and a first flow channel 5 of the core 2. |
