Abstract
The utility model 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, multiple branches are arranged on the two sides of the main respectively and arranged in the length direction of the main at intervals to form a fishbone-shaped plate body, an opening is formed between the branches adjacent on the same side and the main, and corrugations arrayed continuously are formed on the plate body. The fishbone-shaped heat exchanger fin is used for supporting a cooling tube, on one hand, the overall rigidity of the cooling tube is improved, and the first-order natural vibration frequency of a product is increased. On the other hand, the bonding rate of the cooling tube and the built-in fin is increased, and meanwhile the high-boiling region on the liquid side can be reduced; the number of parts can be decreased to facilitate assembly, meanwhile resistance on the liquid side can be reduced, and reliability is good.
Description
Technical field:
The utility model belongs to heat exchanger technical field, refers in particular to a kind of fishbone heat-exchanger fin.
Background technology:
Along with the increasingly stringent of emission request, EGR Technology is applied on power set more and more, and various structure heat exchangers produce in succession.Wherein, plate-fin structure heat exchanger, because of its remarkable heat dispersion, is more applied.
Conventional plate-fin structure heat exchanger, arranges liquid side fin in its cooling fluid side.Liquid side fin is mainly used in the supporting of cooling tube, increases on the one hand the integral rigidity of cooling tube, improves the single order natural frequency of vibration of product; Improve on the other hand the seam rate of cooling tube and built-in fin, the high-boiling region that also can reduce liquid side simultaneously.Conventional liquid side fin is zigzag stagger arrangement fin, and fin is arranged closeer, and liquid collateral resistance is larger, assembling is more loaded down with trivial details; Otherwise the seam rate of cooling tube and built-in fin declines, and affects Performance And Reliability.Therefore current liquid side fin is generally made up of multiple interruptions or continual zigzag stagger arrangement fin, every layer of the product of different length 1 to 10 multiple not etc.; Should meet above-mentioned three large functions, can reduce again number of parts and be convenient to assembling, reduce under the requirement of liquid collateral resistance simultaneously, existing type fin can not meet the demands.
Summary of the invention:
The purpose of this utility model is to provide one and can reduces number of parts and be convenient to assembling, reduces the fishbone heat-exchanger fin of the requirement of liquid collateral resistance simultaneously.
The utility model is achieved in that
A kind of fishbone heat-exchanger fin, include trunk, be respectively arranged with the spaced branch shape of several length directions along trunk in the both sides of trunk and become fishbone plate body, between the adjacent branch of homonymy, be formed with opening with trunk, on plate body, be formed with continuously arranged ripple.
Above-mentioned ripple is rectangle ripple or trapezoidal ripple or triangle ripple.
Above-mentioned opening is rectangular aperture or trapezoid-shaped openings or parallelogram opening.
The branch of above-mentioned trunk both sides is symmetrical arranged.
The setting of staggering of the branch of above-mentioned trunk both sides, the setting of staggering of corresponding opening.
Above-mentioned plate body is that copper product is made or aluminum is made or stainless steel material is made.
The advantage that the utility model is given prominence to is compared to existing technology:
The utility model, for the supporting of cooling tube, increases the integral rigidity of cooling tube on the one hand, improves the single order natural frequency of vibration of product; Improve on the other hand the seam rate of cooling tube and built-in fin, the high-boiling region that also can reduce liquid side simultaneously; Can reduce number of parts and be convenient to assembling, reduce liquid collateral resistance, good reliability simultaneously.

Detailed description of the invention:
With specific embodiment, the utility model is further described below, referring to Fig. 1-9:
A kind of fishbone heat-exchanger fin, include trunk 1, be respectively arranged with the spaced branch 2 of several length directions along trunk 1 in the both sides of trunk 1 and form fishbone plate body, between the adjacent branch 2 of homonymy, be formed with opening 3 with trunk 1, on plate body, be formed with continuously arranged ripple.
Above-mentioned ripple is rectangle ripple or trapezoidal ripple or triangle ripple.
Above-mentioned opening 3 is rectangular aperture or trapezoid-shaped openings or parallelogram opening.The angle b of opening 3 can arrange according to actual conditions, and the big or small c of opening 3 also can determine according to actual conditions.
The branch 2 of above-mentioned trunk 1 both sides is symmetrical arranged (as shown in Figure 8).
The setting of staggering of the branch 2 of above-mentioned trunk 1 both sides, the setting (as shown in Fig. 7, Fig. 9) of staggering of corresponding opening 3.
Above-mentioned plate body is that copper product is made or aluminum is made or stainless steel material is made, and can be also that other materials is made.
Fin in use, can regulate size and the direction of opening 3, to reach easy to assembly, and when meeting reliability, the object that the water side pressure that still can keep lower is fallen.
Fin utilizes mould punching moulding.Fin in use, can regulate size and the direction of opening 3, to reach easy to assembly, and when meeting reliability, the object that the water side pressure that still can keep lower is fallen.
Above-described embodiment is only one of preferred embodiment of the present utility model; not limit practical range of the present utility model with this; therefore: all equivalences of doing according to shape of the present utility model, structure, principle change, within all should being covered by protection domain of the present utility model.
