Abstract
The invention belongs to heat exchanger technology field, refer in particular to 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, be formed with opening with trunk between the branch that homonymy is adjacent, plate body is formed continuously arranged ripple, the present invention is used for the supporting of cooling tube, increase the integral rigidity of cooling tube on the one hand, improve the single order natural frequency of vibration of product; Improve the welded rate of cooling tube and built-in fin on the other hand, also can reduce the high-boiling region of liquid side simultaneously; Number of parts can be reduced and be convenient to assembling, reduce liquid collateral resistance, good reliability simultaneously.
Description
Technical field:
The invention belongs to heat exchanger technology field, refer 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 exchanger produces in succession.Wherein, plate-fin structure heat exchanger, because of the heat dispersion of its brilliance, 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 the integral rigidity of cooling tube on the one hand, improves the single order natural frequency of vibration of product; Improve the welded rate of cooling tube and built-in fin on the other hand, also can reduce the high-boiling region of liquid side simultaneously.Conventional liquid side fin is zigzag offset strip fin, and fin arrangement is closeer, and liquid collateral resistance is larger, assembling is more loaded down with trivial details; Otherwise the welded rate of cooling tube and built-in fin declines, then affect Performance And Reliability.Therefore current liquid side fin is generally interrupted by multiple or continual zigzag offset strip fin forms, the product every layer of different length 1 to 10 multiple not etc.; Should meet above-mentioned three zones, can reduce again number of parts and be convenient to assembling, under reducing the requirement of liquid collateral resistance, existing type fin can not meet the demands simultaneously.
Summary of the invention:
The object of this invention is to provide one can reduce number of parts and be convenient to assembling, reduce the fishbone heat-exchanger fin of the requirement of liquid collateral resistance simultaneously.
The present invention 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, be formed with opening with trunk between the branch that homonymy is adjacent, plate body is formed continuously arranged ripple.
Above-mentioned ripple is rectangle ripple or trapezoidal ripple or triangle ripple.
Above-mentioned opening is trapezoid-shaped openings or parallelogram opening.
Above-mentioned opening is rectangular aperture.
The branch of above-mentioned trunk both sides is symmetrical arranged.
The branch of above-mentioned trunk both sides staggers setting, and corresponding opening staggers setting.
Above-mentioned plate body is that copper product is made or aluminum is made or stainless steel material is made.
The advantage that the present invention gives prominence to compared to existing technology is:
The present invention is used 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 the welded rate of cooling tube and built-in fin on the other hand, also can reduce the high-boiling region of liquid side simultaneously; Number of parts can be reduced and be convenient to assembling, reduce liquid collateral resistance, good reliability simultaneously.

The left view of Fig. 6 to be ripple of the present invention be triangle ripple;
The schematic perspective view of Fig. 7 to be opening shape of the present invention be rectangle;
The schematic perspective view of Fig. 8 to be opening shape of the present invention be parallelogram;
Fig. 9 is opening shape of the present invention is trapezoidal schematic perspective view.
Detailed description of the invention:
With specific embodiment, the invention will be further described below, see 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, be formed with opening 3 with trunk 1 between the branch 2 that homonymy is adjacent, plate body is formed continuously arranged ripple.
Above-mentioned ripple is rectangle ripple or trapezoidal ripple or triangle ripple.
Above-mentioned opening 3 is trapezoid-shaped openings or parallelogram opening.Certain opening also can be rectangular aperture.The angle b of opening 3 can be arranged according to actual conditions, and the size 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 branch 2 of above-mentioned trunk 1 both sides staggers setting, and corresponding opening 3 staggers setting (as shown in Fig. 7, Fig. 9).
Above-mentioned plate body is that copper product is made or aluminum is made or stainless steel material is made, and also can be that other materials is made.
Fin in use, can regulate size and the direction of opening 3, to reach easy to assembly, while meeting reliability, still can keep the object that lower water side pressure is fallen.
Fin utilizes mould punching shaping.Fin in use, can regulate size and the direction of opening 3, to reach easy to assembly, while meeting reliability, still can keep the object that lower water side pressure is fallen.
Above-described embodiment is only one of preferred embodiment of the present invention, not limits practical range of the present invention with this, therefore: all equivalence changes done according to shape of the present invention, structure, principle, all should be covered by within protection scope of the present invention.
