Abstract
A heat exchanger includes a pipe main body forming a flow path to which a first fluid is supplied, a pair of partition plates defining an enclosed space, a plurality of heat transfer tubes, a supply portion configured to supply a second fluid into the enclosed space, a discharge portion configured to discharge the second fluid in the enclosed space, and a flow path forming portion forming a plurality of small flow path portions between the heat transfer tubes adjacent to each other. The second fluid flows between the plurality of heat transfer tubes in the enclosed space in a direction opposite to the flow direction of the first fluid. The plurality of small flow path portions are disposed at positions different from each other in an extension direction when viewed from a position where the discharge portion is disposed.
