Problems solved by technology
The commonly used fins on the liquid side are zigzag staggered fins. The denser the fin arrangement, the greater the liquid side resistance and the more complicated the assembly; on the contrary, the lower the welding rate of the cooling tube and the built-in fins, the performance and reliability will be affected. sex
Therefore, the current liquid side fins are generally composed of multiple discontinuous or uninterrupted zigzag staggered fins, and products of different lengths range from 1 to 10 per layer; Reduce the number of parts to facilitate assembly, and at the same time reduce the liquid side resistance, the existing type of fins cannot meet the requirements

Embodiment Construction
[0024] The present invention will be further described below with specific embodiment, see figure 1 -9:
[0025] A herringbone-shaped heat exchanger fin, including a main body 1, on both sides of the main body 1, several branches 2 arranged at intervals along the length direction of the main body 1 are respectively arranged to form a fishbone-shaped plate body, and the adjacent branches on the same side An opening 3 is formed between the 2 and the main body 1, and continuous corrugations are formed on the plate body.
[0026] The above-mentioned corrugations are rectangular corrugations, trapezoidal corrugations or triangular corrugations.
[0027] The above-mentioned opening 3 is a trapezoidal opening or a parallelogram opening. Of course, the opening can also be a rectangular opening. The angle b of the opening 3 can be set according to the actual situation, and the size c of the opening 3 can also be set according to the actual situation.
[0028] The branches 2 on both...

The invention belongs to the technical field of heat exchangers, and particularly relates to a fishbone-shaped heat exchanger fin. The fishbone-shaped heat exchanger fin comprises a main skeleton. A plurality of branches arranged at intervals in the length direction of the main skeleton are arranged on two sides of the main skeleton respectively and form a fishbone-shaped plate body, openings are formed by adjacent branches on the same side and the main skeleton, and ripples arranged contiguously are formed on the plate body. The fishbone-shaped heat exchanger fin is used for supporting cooling pipes, increases the overall rigidity of the cooling pipes and first-order natural vibration frequency of products on the one hand and increases the welding rate of the cooling pipes and fins arranged internally on the other hand, can also reduce high-temperature boiling regions on the side of liquid and reduce the number of parts to facilitate assembling, reduces resistance on the side of the liquid, and is good in reliability.
Description
Technical field: [0001] The invention belongs to the technical field of heat exchangers, in particular to a herringbone heat exchanger fin. Background technique: [0002] With the increasingly stringent emission requirements, exhaust gas recirculation technology is more and more applied to power plants, and various structural heat exchangers have been produced one after another. Among them, plate-fin heat exchangers are more widely used because of their excellent heat dissipation performance. [0003] In a conventional plate-fin heat exchanger, liquid-side fins are arranged in the cooling liquid side. The fins on the liquid side are mainly used to support the cooling pipe. On the one hand, it increases the overall rigidity of the cooling pipe and improves the first-order natural frequency of the product; The high temperature boiling area on the side. The commonly used fins on the liquid side are zigzag staggered fins. The denser the fin arrangement, the greater the liquid...
