Abstract
A heat exchanger includes an inlet header in which a first inlet space and a second inlet space are formed, a plurality of first inlet-side heat exchanger tubes that are connected to the first inlet space, a plurality of second inlet-side heat exchanger tubes that are connected to the second inlet space, a return header in which a plurality of first return spaces connected to the first inlet-side heat exchanger tubes, respectively, and a plurality of second return spaces connected to the second inlet-side heat exchanger tubes, respectively, are formed, and a plurality of outlet-side heat exchanger tubes that are connected to the first and second return spaces, respectively, wherein a communication path that enables a first return space on a bottom side among the first return spaces and a second return space on a top side among the second return spaces to communicate is formed in the return header.
