Air conditioner
Document Type and Number:
Japanese Patent JP6030039
Kind Code:
B2
Abstract:
A water heat exchanger (51), being a fin-and-tube-type heat exchanger that heats water by exchanging heat between a refrigerant and the water. The water heat exchanger (51) comprises: a plurality of fins (52) having a planar shape and arranged so as to mutually have gaps therebetween; and multi-column pipes (53) piercing and extending from the plurality of fins (52), intersecting the fins (52), and arranged inside a plurality of virtual planes (210, 220) lined up mutually parallel. The multi-column pipes (53) include water pipes (53n) through which water flows and refrigerant pipes (53m) through which refrigerant flows. Each fin (52) is formed from an integrated sheet material, in the direction that the virtual planes (210, 220) are arranged. A fin-and-tube-type heat exchanger and an air conditioner that are produced at low cost can be provided, as a result of this configuration.
