Abstract
A heat exchanger includes a case, a first and second heat exchanger disposed inside the case, a partition member disposed inside the case, and a duct. The case has a first side wall and a second side wall spaced apart from and facing each other in a first direction, a third side wall and a fourth side wall spaced apart from and facing each other in a second direction orthogonal to the first direction, and a bottom wall. A gas outlet communicating with an interior of the case is formed in the first side wall. The first heat exchanger is farther from the bottom wall than the second heat exchanger in a third direction orthogonal to the first and second directions. The second heat exchanger includes meandering heat transfer tubes meandering within a plane orthogonal to the first direction and overlapping along the first direction.
