The technical field is as follows:

the utility model relates to the technical field of refrigeration equipment, in particular to an integral point-array corrugated fin for a high-efficiency heat exchanger.

Background art:

in the existing heat exchanger and other equipment, fins are indispensable parts, the existing fins are generally formed by forming a plurality of air guide through holes on a panel or formed by forming a wavy plate body, the heat exchange area is small, and although the turbulent flow effect of circulating air can be realized, the effect is not obvious.

The utility model has the following contents:

the utility model aims to overcome the defects of the prior art and provides a fin for an integral point-row corrugated high-efficiency heat exchanger, which is provided with a plurality of convex points on a fin main body, thereby increasing the heat exchange area greatly, simultaneously increasing the turbulent flow effect of wind, simultaneously ensuring that part of the wind after blowing through the rear part from one side flows along the arc-shaped circulation groove, ensuring that the wind flows along the arc-shaped circulation groove after blowing to one side wall of a sleeve part, ensuring that both sides and the side edge part of the rear part of the sleeve part exchange heat with the wind, and increasing the heat exchange effect.

The scheme for solving the technical problems is as follows:

a fin for an integral point-row corrugated efficient heat exchanger comprises a fin body, wherein a plurality of connecting through holes are formed in the fin body, and sleeve parts extending upwards are formed on the side parts of the inner side walls of the connecting through holes;

a plurality of protruding points are formed on the top surface of the fin main body, and grooves are formed on the bottom surface of the fin main body corresponding to the protruding points.

Among all the connecting through holes formed in the fin main body, a plurality of transverse protruding strips are formed on the top surface of the fin main body between every two adjacent connecting through holes which are transversely arranged.

And arc-shaped circulation grooves are formed between the end parts of all the transverse convex strips on the two sides of the sleeve part and the sleeve part.

The cross section between all the transverse protruding strips on one side of the sleeve part and the fin main body is wavy.

The outer side wall of the top end of the sleeve part is provided with an outwards-extending flanging part.

All the convex points formed on the top surface of the fin main body are densely distributed on the top surface of the fin main body, and all the convex points are formed on the top surface of the fin main body in a staggered mode.

The utility model has the following outstanding effects:

it sets up a plurality of salient points on the fin main part, has increased greatly increased heat transfer area, simultaneously, it has increased the turbulent effect of wind, simultaneously, the arc circulation groove that it has can guarantee that wind blows rear portion wind from one side and can flow along the arc circulation groove, make wind can flow along the arc circulation groove after blowing a lateral wall of sleeve portion, make the both sides of sleeve portion and the side limit portion at rear portion all carry out the heat transfer with wind, increase heat transfer effect.

Description of the drawings:

FIG. 1 is a schematic view of a partial structure of the present invention;

FIG. 2 is a cross-sectional view A-A of FIG. 1;

fig. 3 is a schematic view of the distribution of the partial bump points of the present invention.

The specific implementation mode is as follows:

in an embodiment, as shown in fig. 1 to 3, a fin for an integral point-row corrugated high-efficiency heat exchanger comprises a fin body 10, wherein a plurality of connecting through holes 11 are formed on the fin body 10, and sleeve portions 12 extending upwards are formed on the inner side wall edge portions of the connecting through holes 11;

the fin body 10 has a plurality of protrusions 13 formed on the top surface thereof, and grooves 14 formed on the bottom surface of the fin body 10 corresponding to the protrusions 13.

Further, of all the connecting through holes 11 formed in the fin body 10, a plurality of transverse protruding strips 15 are formed on the top surface of the fin body 10 between two adjacent connecting through holes 11 arranged transversely.

Further, the arc-shaped flow grooves 1 are formed between the end portions of all the lateral projecting strips 15 on the left and right sides of the sleeve portion 12 and the sleeve portion 12. Second arc-shaped circulation grooves 2 are formed between the boss points 13 at the front and rear of the sleeve portion 12 and the sleeve portion 12, and the second arc-shaped circulation grooves 2 communicate with the corresponding arc-shaped circulation grooves 1.

Further, the cross-section between all the transverse projecting strips 15 on one side of the sleeve portion 12 and the fin body 10 is wavy.

Further, the outer side wall of the top end of the sleeve portion 12 is formed with a flange portion 121 extending outward.

Further, all the protrusions 13 formed on the top surface of the fin body 10 are densely distributed on the top surface of the fin body 10, and all the protrusions 13 are formed on the top surface of the fin body 10 in a staggered manner.

When the heat exchanger is used, wind blows from one side and contacts with the convex points 13 on the fin body 10 to increase the turbulent effect of the wind, and then partial wind blows to the sleeve part 12 and flows to the second arc-shaped circulation grooves 2 along the arc-shaped circulation grooves 1 on two sides, so that the wind can contact with the whole annular outer side wall of the sleeve part 12, the heat exchange contact surface with the sleeve part 12 is increased, and the heat exchange effect is improved.
