Abstract

A heat exchanger includes a first tube in which water flows and a second tube in which refrigerant flows, and performs heat exchange between water and refrigerant. The first tube and the second tube are bonded to each other by brazing at joint surfaces thereof such that water flow crosses refrigerant flow perpendicularly. The joint surface of the first tube is divided into several surface regions by grooves. Accordingly, the joint surface of the first tube can be brazed to the joint surface of the second tube uniformly.
