Problems solved by technology

[0002] The heat exchangers used in existing refrigeration and air-conditioning equipment use different forms of fins. Although their air-side heat transfer coefficients and resistance characteristics are different, their common disadvantages are that the heat transfer area is small and the finning coefficient is relatively small. Small, poor heat exchange performance

Embodiment

[0014] The structure diagram of the present invention is as figure 1 As shown, it includes a heat exchanger tube 4 and fins 2 arranged on the heat exchanger tube 4 , wherein the fin 2 is a strip-shaped fin fixed on the outer surface of the heat exchanger tube 4 in a spiral shape.

[0015] For ease of installation, the above-mentioned strip fins 2 include a substrate 1 and a plurality of fins 21. The plurality of fins 21 are erected and fixed on the substrate 1, and then spirally wound on the heat exchanger tube 4 through the substrate 1. .

[0016] In order to ensure the uniformity of heat exchange in the present invention, the plurality of fins 21 are fixed on the substrate 1 at equal intervals along the circumferential direction.

[0017] In order to further increase the installation speed, thereby improving the productivity of the present invention, the substrate 1 is fixed with several rows of fins 21 arranged at equal intervals in the axial direction, such as two or thre...

Fins are vertically installed on basal pieces. Basal pieces enwinds on pipes of heat exchanger in helical shape. Features are: large heat transfer surface area, large rib coefficient and good performance of heat exchange. Features are: smart design, new and reasonable structure

Description

1. Technical field: [0001] The invention relates to a heat exchanger used in refrigeration and air-conditioning equipment, which belongs to the transformation technology of the heat exchanger. 2. Background technology: [0002] The heat exchangers used in existing refrigeration and air-conditioning equipment use different forms of fins. Although their air-side heat transfer coefficients and resistance characteristics are different, their common disadvantages are that the heat transfer area is small and the finning coefficient is relatively small. Small, poor heat exchange performance. 3. Contents of the invention: [0003] The object of the present invention is to provide a heat exchanger with large heat transfer area, large ribbing coefficient and good heat exchange performance in consideration of the above problems. [0004] The structure diagram of the present invention is as figure 1 As shown, it includes heat exchanger tubes (4) and fins (2) arranged on the heat exc...
