Abstract
A heat exchanger includes: a main body; and a tube sheet that is bonded to the main body with a brazing material and is used to fix the main body to a support by a fixing member. The tube sheet includes: a bonding surface to which the brazing material is applied; a rising portion that rises from the bonding surface; and a through-hole through which the fixing member is passed. The through-hole is opened at the rising portion, penetrates the tube sheet, and has an inner peripheral surface to which the brazing material is not applied. The main body includes heat transfer tubes through which refrigerant flows, and the tube sheet is bonded to surface of the heat transfer tube.
