<p>PROBLEM TO BE SOLVED: To provide a heat exchanger capable of suppressing reduction in heat exchange efficiency and improving heat exchange performance.SOLUTION: A heat exchanger includes: a plurality of refrigerant tubes 40; refrigerant header 41 and 42; a plurality of water tubes 50; and water header 51 and 52. The refrigerant headers 41 and 42 are connected to both ends of the refrigerant tubes 40, respectively for assembling refrigerant. The water headers 51 and 52 are connected to both ends of the water tubes 50, respectively for assembling water. The heat exchanger includes joint regions and non-joint regions. In each joint region, the refrigerant tubes 40 and the water tubes 50 are joined together in a stacked state along an extension direction of the refrigerant headers 41 and 42 and the water headers 51 and 52, and heat exchange is accelerated between the refrigerant flowing in the refrigerant tubes 40 and the water flowing in the water tubes 50. In each non-joint region, the refrigerant tubes 40 and the water tubes 50 are not stacked, and heat exchange is suppressed between the refrigerant flowing in the refrigerant tubes 40 and the water flowing in the water tubes 50. Each non-joint region is disposed between the joint regions.</p> |
