Problems solved by technology

However, due to the solid structure of the convex hull and the smaller air-side flow area, the wind resistance increases, which in turn leads to a decrease in the overall performance of the fins.

Embodiment 1

[0029] This preferred embodiment provides a heat exchanger fin. Such as figure 1 with figure 2 As shown, the fin 1 includes a connected fin body 11 and a fin edge 12, the fin body 11 is provided with a flat tube groove 111 for passing through the flat tube 2, and the fin body 11 and / or the fin edge A support 101 is protrudingly provided on the surface of 12 . The support member 101 is in the shape of an arch bridge, and opening structures are provided on both sides of the support member 101 , and the opening structures form the wind passage 102 along the surface of the fin 1 .

[0030] The wind passing channel 102 formed between the support member 101 and the surface of the fin 1 is beneficial to reduce the wind resistance of the fin, the comprehensive performance of the fin 1 is further improved, and the noise generated when the wind flows through the fin 1 is reduced.

[0031] A plurality of arched fin bridges 112 are arranged on the fin body 11 . Opening structures are...

Embodiment 2

[0037] This preferred embodiment provides a heat exchanger fin whose structure is basically the same as that of the first preferred embodiment. The fin includes a connected fin body and a fin edge, the fin body is provided with a flat tube groove for passing through a flat tube, and a support member is protrudingly provided on the surface of the fin body and / or the fin edge , the supporting member is in the shape of an arch bridge, and opening structures are arranged on both sides of the supporting member, and the opening structures form air passages along the surface of the fins.

[0038] The difference is that no other structures (fin bridges, corrugated protrusions, ribs, etc.) Fin wind resistance.

Embodiment 3

[0040] This preferred embodiment provides a heat exchanger. Such as image 3 with Figure 4 As shown, the heat exchanger includes a plurality of flat tubes 2 and a plurality of fins 1 as described in the preferred embodiment 1 or 2, and the flat tubes 2 are snapped into the flat tube grooves 111 .

[0041] The support separates two adjacent fins at a certain distance to ensure sufficient air flow through the fins to avoid serious attenuation of the performance of the whole machine due to condensation and frost.

[0042] Each fin 1 is sequentially stacked forward to form a fin group, and a plurality of flat tubes 2 are respectively snapped into the flat tube grooves 111 of the fin group, and the distance between the fins is equal to the height of the support; or, the plurality of fins 1. The fin group is formed by stacking forward and reverse in sequence, and a plurality of flat tubes 2 are respectively snapped into the flat tube grooves 111 of the fin group. The bridge heig...

Abstract

The invention discloses a heat exchanger fin and a heat exchanger and belongs to the field of heat exchangers and accessories thereof. The problems that existing fins are high in wind resistance are solved. The heat exchanger fin comprises a fin body and a fin side which are connected. A flat pipe groove for flat pipe penetrating is formed in the fin body. A supporting piece is arragned on the surface of the fin body and / or the fin side in a protruding mode. The supporting piece is in an arch bridge shape. Opening structures are arranged on the two side faces of the supporting piece. The opening structures form air passing channels along the surface of the fin. The heat exchanger comprises the flat pipe and the fin. The flat pipe is clamped into the flat pipe groove. The heat exchanger fin lowers fin resistance, the comprehensive performance of the fin is improved, and the problem that condensation water and defrosting water of a micro-channel heat exchanger for a heat pump cannot be discharged easily can be effectively solved. The heat exchanger well balance heat exchanging performance and fin wind resistance performance, and the problem that condensation water and defrosting water cannot be discharged easily is solved.

Description

technical field [0001] The invention relates to a heat exchanger fin and a heat exchanger equipped with the fin. Background technique [0002] Microchannel heat exchanger is a new type of high-efficiency heat exchanger, which has the advantages of high heat transfer efficiency, small size, light weight, and less charge. The fins of the microchannel heat exchanger are rolled into a wave shape by a rolling mill, and then brazed between the upper and lower flat tubes. The position between the flat tubes is a continuous corrugated fin structure, and the condensed water is easy to stay in the fin gap of the heat exchanger. Accumulate on the upper surface of the flat tube and the root of the V-shaped fin. [0003] In order to reduce wind resistance and improve the problem of condensate frosting, there is a slotted fin with convex hulls (supports) at both ends. After installation, the convex hulls of two adjacent fins face each other, so that Controllable fin spacing is achieved...
