Abstract

A heat exchanger with an increased heat exchange efficiency between two fluids. The heat exchanger is constituted of an inner tube (4) and an outer tube (6). The inner tube (4) has double walls (5) where a first wall (5a) and a second wall (5b) are in tight contact with each other. The outer tube (6) is substantially coaxial with the inner tube (4) and has the inner tube (4) in the inside. A first fluid flows inside the inner tube (4) and a second fluid flows in the annular portion between the inner tube (4) and the outer tube (6). Although the heat exchanger has a very simple structure with the double walls (5) securing safety between the first fluid and the second fluid, a sufficient contact area can be obtained between the first fluid flow path and the second fluid flow path. As a result, high heat exchanging efficiency can be achieved.
