PROBLEM TO BE SOLVED: To provide a heat exchanger which can prevent the plastic deformation of a tube without inviting an increase in pressure loss.SOLUTION: In the heat exchanger, in which a first space A connected to a heated fluid lead-in port 45, a second space B connected to a heated fluid lead-out port 48, and a third space C which is located between the first space A and the second space B and is connected to a heating fluid lead-in port (pipe 46) and to a heating fluid lead-out port (pipe 47) are formed in an enclosure case 41, the heat exchanger is provided with a plurality of tubes 44, 44... whose one-side open ends are open to the first space A, other-side open ends are open to the second space B, and middle portions are arranged in parallel with the third space C, with a lead-in-side partition member 42 which partitions the first space A from the third space C and slidably supports the one-side ends of the tubes 44, and with a lead-out-side partition member 43 which partitions the second space B from the third space C and slidably supports the other-side ends of the tubes 44. |
