Document Type and Number:
WIPO Patent Application WO/2019/240055
Kind Code:
A1
Abstract:
Provided are a heat exchanger and an air conditioner capable of preventing a decrease in fin efficiency. An indoor heat exchanger (51) comprises a plurality of indoor flat tubes (55) and a plurality of indoor fins (60). The indoor fins (60) are joined to the plurality of indoor flat tubes (55), which are arranged at a predetermined pitch (DP) in the vertical direction. The plurality of indoor flat tubes (55) includes a first row (76) composed of a plurality of first flat tubes (56) and a second row (77) composed of a plurality of second flat tubes (57). The plurality of indoor fins (60) include a first heat transfer fin (66) joined to the plurality of first flat tubes (56) in the first row (76), and a second heat transfer fin (67) joined to the plurality of second flat tubes (57) in the second row (77). A distance (D1) between a first end (66a) of the first heat transfer fin (66) and a first center position (86a) is DP × a. A distance (D2) between a second end (66b) of the first heat transfer fin (66) and a second center position (86b) is DP × b. A distance (D3) between a third end (67a) of the second heat transfer fin (67) and a third center position (87a) is DP × b. A distance (D4) between a fourth end (67b) of the second heat transfer fin (67) and a fourth center position (87b) is DP × a. In the indoor heat exchanger (51), the relationships of 0.1 < a < 1, 0.1 < b < 1, a < b, and a + b < 1 are satisfied.
