Abstract

The invention provides a finned tube heat exchanger that is improved in heat exchange performance. The finned tube heat exchanger comprises multiple fins (1) laminated in a mutually spaced manner, and multiple heat transfer tubes (2) penetrating the multiple fins (1) in the lamination direction, wherein fluids for heat exchange of air flows flowing among the multiple fins (1) flow across the heat transfer tubes (2). Each fin (1) is provided with ripple-shaped portions alternatively appearing between peak portions (6a, 6b) and a valley portion (7) of air flows (3) in the flowing direction. In the flowing direction of the air flows (3), a ridge line (10) of one peak portion (6b) between two adjacent heat transfer tubes (2) in the plumb direction, positioned at a side lower than the central portion of each fin (1), is equipped with an air window (9).

Description

technical field [0001] The present invention relates to a finned tube heat exchanger for heat exchange of refrigerant. Background technique [0002] For a long time, such finned tube heat exchangers as Figure 8 What is shown includes: a plurality of fins 101 stacked at intervals; and a plurality of heat transfer tubes 102 provided to pass through the plurality of fins 101 in the stacking direction. [0003] In this finned tube heat exchanger, an air flow 103 such as air blown by a blower (not shown) flows between adjacent fins 101 , thereby interacting with the fluid flowing inside the heat transfer tubes 102 . heat exchange. [0004] As a finned tube heat exchanger having such a structure, it is disclosed, for example, in Patent Document 1 (Japanese Unexamined Patent Publication No. 2001-091101). [0005] Figure 9A It is a partial plan view of the fins included in the conventional fin-tube heat exchanger. Figure 9B yes Figure 9A A0-A0 line sectional view. Figure ...
