PURPOSE:To enable a heat exchanger to display its heat-exchanging performance and to be easily manufactured, by a construction wherein a heat exchanger is constituted of a cylindrical casing, a pipe member affixed to the inner periphery of the casing in a substantially wound state, and heat-exchanging plates disposed in the casing with the outer peripheral edges supported in contact with the pipe member. CONSTITUTION:The pipe member 2 is affixed to the inner periphery of the cylindrical casing 1, and a plurality of heat-exchanging plates 3 permeable to fluids are disposed on the inside of the pipe member 2, with the outer peripheral edges 3a thereof supported in contact with the pipe member 2. A high- pressure gas H introduced through an upper high-pressure port 11 flows through a high-pressure passage 17 in the member 2, and is led out through a lower high-pressure port 12. On the other hand, a low-pressure gas L introduced through a lower low-pressure port 13 flows up sequentially through through-holes of the plates 3, and is discharged to the exterior of the casing 1 through the upper low-pressure port 14. The gas L and the gas H exchange heat with each other through the pipe member 2 and the plates 3.
