Description

Technical Field

[0001] The utility model relates to the technical field of radiators, in particular to the field of radiator cooling fins, and specifically refers to a high-performance cooling fin. Background Art

[0002] The radiator in the engine water cooling system is used to cool the high-temperature coolant. The coolant in one water chamber can flow through the radiator tubes to the other water chamber, and the coolant flows inside the radiator core. When the coolant flows through the radiator core, it will encounter the cooling fan and the air generated by the movement of the vehicle, and the air passes outside the radiator core. The hot coolant becomes cold due to heat dissipation to the air, and the cold air warms up because it absorbs the heat dissipated by the coolant. That is, the hot coolant becomes cold coolant after flowing through the radiator tubes and cooling fins due to heat dissipation to the air. Thus, the cooling effect is achieved, so the radiator is a heat exchanger.

[0003] The radiator in the engine water cooling system mainly consists of two parts: a water chamber and a radiator core. As Figure 6 shown, the radiator core is composed of main plates, guard plates, radiator tubes, and cooling fins. The radiator tubes and cooling fins of the radiator core are mostly made of aluminum. The aluminum radiator tubes are made into a flat shape, and the cooling fins are corrugated, focusing on heat dissipation performance. The installation direction is perpendicular to the direction of air flow. The cooling fins are provided with window cut surfaces similar to louvers for disturbing the air flow to break the adhesion layer of the flowing air on the surface of the cooling fins and improve the heat dissipation capacity.

[0004] The window cut surface of the traditional cooling fin is a plane, and its heat dissipation effect is average. For example, the utility model patent with the publication number CN203518750U: a windowed cooling fin for a radiator, the size of the window is the same in each width, so the window is a long slit, and it is difficult for the heat dissipation effect to meet the heat dissipation requirements of the existing radiator. Content of the Utility Model

[0005] The utility model aims at the deficiencies of the prior art and provides a high-performance cooling fin.

[0006] The utility model is realized by the following technical solutions: providing a high-performance cooling fin, which is of a wavy structure and includes a plurality of flat plates and a plurality of arc-shaped connecting plates connected alternately. The long sides of the flat plates are connected to the arc-shaped connecting plates. The flat plates are provided with a plurality of window openings arranged along the length direction. The window openings include window openings punched out towards both sides of the flat plate. The end surface of the window opening is an arc, and the distance from the arc to the flat plate is H, and the H gradually decreases from the middle of the arc to both ends.

[0007] In this solution, the end surface of the window opening is an arc, that is, the flow-through surface of the window opening is arc-shaped, the area of the ventilation cavity increases, which is convenient for air to pass through, and the disturbing flow effect is increased.

[0008] As an optimization, the opening directions of the openings on the same side at both ends of the flat plate are opposite. Thus, the wind can flow turbulently on both sides of the flat plate, improving the turbulence effect.

[0009] As an optimization, a partition plane is provided in the middle of the flat plate, and the opening directions of the openings on the same side on both sides of the partition plane are opposite. There are no openings provided on the partition plane in this solution, so it plays a certain strengthening role here.

[0010] As an optimization, the arc includes a large arc segment in the middle and small arc segments at both ends, and the radius of the small arc segment is smaller than that of the large arc segment. By setting the small arc segments, the size of the opening can be quickly increased, and the area of the flow-through surface of the opening can be increased.

[0011] As an optimization, the included angle between adjacent flat plates is 10 - 25 degrees. To achieve a good heat dissipation effect

[0012] As an optimization, the opening angle at the middle position of the arc is a and a is 30° - 50°. Therefore, the maximum opening angle is 30° - 50°.

[0013] As an optimization, the sizes of the openings on both sides in the opening part are the same. Therefore, it is convenient for processing and improves versatility.

[0014] The beneficial effects of the present utility model are as follows: A high-performance heat dissipation strip of the present utility model, the cross-section of the opening of the high-performance heat dissipation strip is designed as an arc. Through simulation analysis, the cross-section is changed from a plane to an arc shape, the area of the ventilation cavity formed by the cross-section is increased, the turbulence effect is increased, and the heat dissipation efficiency is greatly improved.

[0025] To clearly illustrate the technical features of this solution, the following is an elaboration of this solution through specific embodiments.

[0026] As Figures 1 - 8 shown, a high-performance heat dissipation belt of the present utility model has a wavy structure and is formed by bending an aluminum plate. It includes a plurality of flat panels 1 and a plurality of arc-shaped connecting plates 2 that are alternately connected. The included angle between adjacent flat panels 1 is 10 - 25 degrees. The arc-shaped connecting plate 2 is tangent to the flat panel 1 at the connection, so the central angle of the arc-shaped connecting plate 2 is less than 180 degrees.

[0027] The long side of the flat panel 1 is connected to the arc-shaped connecting plate 2, Figure 1 which reflects the width and thickness of the flat panel, Figures 3 - 5 and the vertical direction in it is the length of the flat panel.

[0028] A plurality of opening window parts are arranged on the flat panel 1 along the length direction. A dividing plane 4 is provided in the middle of the flat panel 1, and no opening window parts are provided on the dividing plane 4 to improve the strength in the middle. The opening window parts on both sides of the dividing plane 4 are vertically equal.

[0029] The opening window part includes an opening window 3 punched out towards both sides of the flat panel 1. As Figure 2 , 6 shown, the flat panel 1 at the position of the opening window part is punched towards both sides by a punch, so as to form opening windows 3 on both sides. The opening windows 3 on both sides in the opening window part are of the same size.

[0030] The opening directions of the opening windows 3 on the same side at both ends of the flat panel 1 are opposite. Specifically, as Figure 7 shown, the opening directions of the opening windows 3 on the same side on both sides of the dividing plane 4 are opposite.

[0031] The end face of the opening window 3 is an arc, and the distance between the arc and the flat panel 1 is H. The H gradually decreases from the middle of the arc towards both ends. The opening angle at the middle position of the arc is a and a is 30° - 50°. The opening angle gradually decreases from the middle position of the arc towards both ends. As Figure 3 shown is the opening angle at the middle position, which is the largest.Figure 4 The window opening angle of Figure 3 is smaller, Figure 5 The window opening angle of Figure 4 is smaller.

[0032] As Figure 2 shown, the arc includes a large arc segment in the middle and small arc segments at both ends. The connections between the large arc segment and the small arc segments are tangent. The radius of the small arc segment is smaller than that of the large arc segment, thereby increasing the distance between the end of the large arc segment and the flat plate 1.

[0033] Of course, the above description is not limited to the above examples. The technical features not described in the present utility model can be achieved by or adopted from the prior art, and will not be elaborated here; the above embodiments and drawings are only used to illustrate the technical solutions of the present utility model and are not limitations to the present utility model. The present utility model has been described in detail by referring to the preferred embodiments. Those of ordinary skill in the art should understand that any changes, modifications, additions or substitutions made by those of ordinary skill in the art within the scope of the essence of the present utility model do not depart from the purpose of the present utility model and should also fall within the scope of protection of the claims of the present utility model.
