Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchange devices, in particular to a high-efficiency evaporative refrigeration fin tube. Background Art

[0002] Finned tube is a heat exchange device, which completes the heat exchange between the inside and outside of the tube through the heat transfer of the finned tube, so as to adjust the indoor temperature. Especially in the refrigeration industry, the refrigerant discharged by the evaporative refrigeration equipment passes through the finned tube, and the finned tube absorbs the indoor heat and is taken away by the refrigerant, so as to achieve the effect of cold storage. The inner diameter of the traditional finned tube is mostly designed to be φ25mm or φ32mm to ensure the refrigerant flow, so as to ensure the refrigeration effect.

[0003] However, the existing finned tubes have a large refrigerant filling volume and low heat exchange efficiency, resulting in high refrigeration energy consumption. This solution solves this technical problem. Utility Model Content

[0004] The utility model aims to provide a high-efficiency evaporative refrigeration fin tube, which solves the technical problem of poor refrigeration effect of existing fin tubes. The inner side of the tube body is designed as a toothed structure, and the side of the fin is provided with wave patterns, which improves the heat exchange efficiency and reduces the energy consumption per unit cooling capacity.

[0005] A high-efficiency evaporative refrigeration fin tube comprises a tube body and two fins with one side connected to the outside of the tube body, the side of the fin is smooth or provided with wavy patterns along the radial direction of the tube body, the other side of the fin is an arc edge, and the inner side of the cross section of the tube body is toothed.

[0006] Two sides of one side of the fin are tangent to the outer side of the tube body respectively.

[0007] The fin includes a connecting portion with one end facing the side of the tube body and an extending portion arranged at the other end of the connecting portion.

[0009] The thickness of the fin is 1-2 mm.

[0010] The maximum inner diameter of the tube body is φb, wherein φb≤12mm, and the outer diameter of the tube body is φa, wherein φa≤15mm.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The inner side of the tube is designed as a toothed structure, and the maximum inner diameter of the tube is designed to be 8 mm. Compared with the existing inner circular cross-section, the heat exchange efficiency is higher and the amount of refrigerant used is less. The side of the fin is provided with a wave pattern, which makes the outer surface area of ​​the fin larger, further improving the heat exchange efficiency and reducing the energy consumption per unit cooling capacity;

[0022] In order to more clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0023] Example 1: See Figure 1 , Figure 2 , Figure 5A high-efficiency evaporative refrigeration fin tube includes a tube body 1 and two fins 2 with one side connected to the outside of the tube body 1. The side of the fin is smooth or has wavy patterns along the radial direction of the tube body. The other side of the fin 2 is an arc edge 21. The inner side of the cross section of the tube body 1 is serrated.

[0024] Both sides of one side of the fin 2 are tangent to the outer side of the tube body 1 respectively.

[0025] The fin 2 includes a connecting portion 22 disposed at one end opposite to the side of the tube body 1 and an extending portion 23 disposed at the other end of the connecting portion 22. Both sides of one side of the connecting portion 22 are tangent to the outer side of the tube body 1 respectively. The two extending portions 23 are disposed in parallel, and the other end of the extending portion 23 is an arc edge 21.

[0026] The thickness of the fin 2 is 1 mm.

[0027] The maximum inner diameter of the tube body 1 is φb, where φb=8mm, and the outer diameter of the tube body 1 is φa, where φa=11.5mm.

[0028] The specific working process of this utility model:

[0029] When using, see Figure 5 , install the fin tube on the wall or roof so that the spacing between the fins 2 is equal, and the fin tube is fixed to the ground or wall through the tube body 1. The fin tube can be connected in series or in parallel according to the site environment ( Figure 5 For series connection), after the fin tubes are installed, the fin tubes are connected to the output end of the evaporative refrigeration equipment. The evaporative refrigeration equipment fills the refrigerant into and passes through the tube body 1. The heat of the external environment is absorbed through the extension part 23 of the fin 2, and then transferred to the connecting part 22. Since the two sides of one side of the connecting part 22 are tangent to the outer side of the tube body 1 respectively, the contact area between the connecting part 22 and the tube body 1 is large, so the efficiency of transferring to the tube body 1 through the fin 2 is high, and the heat can be transferred to the refrigerant in the tube body 11 in time. The heat is taken away by the refrigerant and flows into the evaporative refrigeration equipment, thereby reducing the indoor temperature and achieving the cooling effect;

[0030] The inner side of the tube body 1 is designed as a toothed structure, and the maximum inner diameter of the tube body 1 is 8mm, which is convenient for use and installation with the matching evaporative refrigeration equipment, and has higher heat exchange efficiency, while reducing the amount of refrigerant filling. The side of the fin 2 is provided with a corrugated pattern, and the corrugated pattern makes the outer surface area of ​​the fin 2 larger, thereby improving the heat exchange efficiency and reducing the energy consumption per unit cooling capacity;

[0031] The other end of the extension portion 23 is a circular arc edge 21 , so that the surface area of ​​the fin 2 is larger, and the installation and use are safer. The design of the circular arc edge 21 also makes the strength of the fin 2 higher.

[0032] Example 2: Based on Example 1, see Figure 3 , Figure 4 The fin 2 includes a connecting portion 22 connected to the tube body 1 at one end, and the two connecting portions 22 are arranged at an acute angle. Specifically, the angle between the two connecting portions 22 is 40°. The two sides of one side of the two connecting portions 22 are tangent to the outer side of the tube body 1 respectively. The other ends of the two connecting portions 22 are provided with extension portions 23. The two extension portions 23 are arranged in parallel, and the other ends of the extension portions 23 are arc edges 21.

[0033] By setting the connection portion 22 of the fin 2 at an acute angle, the fin tube can be adapted to installation in different positions, so that the fin tube has stronger applicability and higher heat exchange efficiency in different environments.

Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
