Problems solved by technology

[0009] However, when the gap 130 is filled with a filler, when the heat exchanger 100 is discarded, as waste materials, in addition to the heat transfer fins 120 and the heat transfer tubes 110 made of metal, a foreign material such as a filler is generally added. materials, thus making classification of materials difficult
As a result, recyclability deteriorates, leading to an increase in environmental load

Embodiment approach

[0057] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited by the following embodiments.

[0058] Figure 1 ~ Figure 3 The fin-and-tube heat exchanger 1 according to an embodiment of the present invention is shown. The heat exchanger 1 includes: a plurality of overlapping heat transfer fins 3; a pair of side plates 20 arranged on both sides of the heat transfer fins 3; and the heat transfer fins 3 and the side plates 20 are passed through in a string 的Multiple U-shaped heat transfer tubes 2.

[0059] Each heat transfer fin 3 extends in a specific direction, and the linear portions of each heat transfer tube 2 are arranged along the length direction of the heat transfer fin 3 at a predetermined pitch. Both end portions of each heat transfer tube 2 protrude from the side plate 20 on the opposite side to the turn-back portion that connects the linear portions to each other, and the end port...

Abstract

A heat transfer fin (3) includes: a base portion (4) having a flat surface (4a); a cylindrical collar portion (5) extending upwardly from the base portion (4); a flared portion (6) flaring radially outwardly from an entire upper end of the collar portion (5); and a receding portion (7) having an inclined surface extending upwardly from a bottom of the collar portion (5) at an acute angle with respect to a direction toward the upper end of the collar portion (5). The bottom of the collar portion (5) is located at a position not reaching a reference plane when the flat surface (4a) of the base portion (4) is the reference plane.

Description

Technical field [0001] The present invention relates to a fin-tube heat exchanger and a heat pump device using the fin-tube heat exchanger. In addition, the present invention relates to heat transfer fins suitable for fin-tube heat exchangers. Background technique [0002] Conventionally, fin-tube type heat exchangers have been used in heat pump devices and the like. For example, Patent Document 1 discloses Figure 8 A fin-tube type heat exchanger 100 as shown. [0003] The heat exchanger 100 includes a plurality of stacked heat transfer fins 120 and a heat transfer tube 110 penetrating the heat transfer fins 120. Each heat transfer fin 120 includes a cylindrical (constant cross-sectional shape) ring portion 123 standing up from the base portion 121. The base portion 122 and the expanded portion 124 expand radially outward while being bent from the base and tip of the ring portion 123. The flared portion 124 of one of the adjacent heat transfer fins 120 is in contact with the vi...
