Description

Technical Field

[0001] The present application relates to the technical field of radiators, and in particular to a radiator fin arranged based on a reflective flow field. Background Art

[0002] Finned radiator is a relatively common radiator. The usual process is to first use a mold to produce the fins, then pass a long U-shaped copper tube into the tube hole formed by the fin flange, then expand the fin to ensure the fixation of the fin and the copper tube, and finally weld a small U-shaped copper tube at the end to form a closed loop space, and finally inject refrigerant into the loop space.

[0003] When in use, the radiator will be used in conjunction with a cooling fan, which provides wind on one side of the radiator to help remove heat. A problem may arise during use. The flange of the radiator fin will have a windward side and a leeward side, and there will be a temperature difference. The temperature difference on the fin itself will affect the overall heat conduction efficiency, and the local temperature difference of the material will cause deformation; in addition, the temperature difference will also cause differences in the amount of condensed water formed, that is, more condensed water on one side and less on the other side, which will further affect the heat conduction efficiency of the fin. Because the amount of condensed water on both sides of the flange is different, the condensed water merges with each other on the outer peripheral surface of the flange, making it easier to form a water film and not easy to stay. Summary of the invention

[0012] The present application also proposes a radiator fin based on a reflective flow field arrangement, which is used to process the above-mentioned radiator fin, wherein the reflective plate processed in the first manner is integrally formed with the reinforcing rib structure forming the third water flow channel, and at least four groups of reflective plates are arranged, two of which are located on the leeward side of the flange, and the other two groups are located on the windward side of the flange;

[0013] The height of the two groups located on the windward side of the flange is between one third and one half of the flange height;

[0014] The four groups of reflective plates are distributed in a circular array relative to the flange.

[0015] In a radiator fin based on a reflective flow field arrangement provided in the present application, at least four groups of reflective plates processed in the second manner are arranged, two of which are located on the leeward side of the flange, and the other two are located on the windward side of the flange;

[0016] The four groups of reflective plates have the same structure and are distributed in a circular array relative to the flanges.

[0017] In a radiator fin based on a reflective flow field arrangement provided in the present application, the reflective plate has an arc-shaped structure, and the curvature of the reflective plate is between π / 6-π / 4.

[0018] In a radiator fin based on a reflective flow field arrangement provided in the present application, each set of reflective plates includes a guide plate and a radiation plate that are spaced apart from each other, and the tangent direction of the radiation plate is parallel to the tangent direction of the outer periphery of the flange that the radiation plate faces, or forms an angle of less than 10°;

[0019] The tangent direction of the guide plate and the tangent direction of the radiation plate form an angle between 20° and 50°;

[0025] The present application also innovatively combines the reinforcing rib structure with the water flow trough, and there is no need to process the water flow trough separately through an additional process.

The efficiency of discharging condensed water is improved, thereby extending the service life of the radiator.

[0040] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0041] This embodiment proposes a heat sink fin based on a reflective flow field arrangement.

[0042] Radiator fin structure reference Figure 1As shown, it includes a fin plate body 4, on which a tube hole is arranged, and the tube hole is drawn around to form a flange 7, and a reflective plate 5 is arranged at intervals on the leeward side of the flange 7. The reflective plate 5 is provided with a reflective surface relative to the heat dissipation air flow field provided by the heat dissipation fan, and the reflective surface is arranged toward the leeward outer peripheral surface of the flange 7.

[0043] The height of the fin plate body 4 protruding from the reflector 5 is consistent with the height of the fin plate body 4 protruding from the flange 7, and is usually no more than 2 cm.

[0044] The main idea of ​​the present invention is to provide a reflector 5 to reflect the wind of the heat dissipation fan to the leeward side of the flange 7, thereby accelerating heat exchange and avoiding a temperature difference in a part of the flange 7.

[0045] In addition to solving the basic temperature difference problem, the present invention designs a water flow groove structure to facilitate the discharge of condensed water on the fins. The present invention combines the water flow groove structure with the reinforcing rib structure. The specific method is as follows: the surface of the fin plate body 4 is provided with a reinforcing rib structure, and the area between adjacent reinforcing rib structures forms a water flow groove, and the water flow groove includes a first water flow groove 1, a second water flow groove 2 and a third water flow groove 3;

[0046] The first water flow channel 1 and the second water flow channel 2 extend along the length direction of the fin plate body 4 , the third water flow channel 3 is located at the bottom of the flange 7 , is arranged along the outer periphery of the flange 7 , and is connected to the first water flow channel 1 and the second water flow channel 2 .

[0047] The reinforcing rib structure is formed by bending the fin plate body 4, referring to Figure 1 and Figure 2 , the reinforcing ribs are parallel to each other, and the middle part is naturally concave to form a water flow channel structure. Figure 5 and Figure 6 As shown, a thickening layer 10 is provided at the bending position. The thickening layer 10 can be a thick material layer reserved when the fin plate body 4 is formed, or a double-layer thickening structure is directly folded. It is also possible to weld a layer of sheet material at the bottom after the fin plate body 4 is formed to achieve thickening. The thickening layer 10 improves the reinforcing effect of the reinforcing member, and this design can be beneficial to the bending resistance of the fin plate body 4 in the length direction.

[0048] Drainage grooves 6 are provided on both sides of the third water flow groove 3, and the drainage grooves 6 are used to communicate with the first water flow groove 1 and the second water flow groove 2;

[0049] The third water channel 3 is provided with a protrusion 8 adjacent to the first water channel 1 and the second water channel 2. The protrusion 8 is located outside the position adjacent to the leeward side and the windward side of the flange 7, and the drainage groove 6 is formed on both sides of the protrusion 8. The protrusion 8 is also a component of the reinforcing rib structure, which can avoid the loss of stability of the peripheral structure of the flange 7 caused by the design of the drainage groove 6. The function of the protrusion 8 is also to guide the condensed water of the third water channel 3, which can help the condensed water of the third water channel 3 quickly enter the first water channel 1 and the second water channel 2 on both sides.

[0050] Based on the design of the reinforcing rib structure and the reflector 5 structure, a unified planning is made in terms of process.

[0051] Especially the processing technology of the reflector 5, the reflector 5 has two processing methods, the first method: directly stretching or extruding the fin plate body 4 plane to form a protrusion, the second method: cutting a shape on the fin plate body 4 and retaining a common edge with the fin plate body 4, and forming it by folding the common edge.

[0052] Processing in the first way The reflective plate 5 processed in the first way is integrally formed with the reinforcing rib structure forming the third water flow channel 3, and at least four groups of reflective plates 5 are provided, two of which are located on the leeward side of the flange 7, and the other two are located on the windward side of the flange 7;

[0053] The height of the two groups located on the windward side of the flange 7 is between one-third and one-half of the height of the flange 7; the four groups of reflective plates 5 are distributed in a circular array relative to the flange 7. The reflective plates 5 processed in the first way form a reinforcement structure around the flange 7, which improves the stability of the connection between the tube hole and the copper tube, and can also achieve the effect of reflecting the wind field. The additional reflective plates 5 on the windward side have three functions. The first is to improve the structural reinforcement effect; the second is that due to the low height of the reflective plates 5 on this side, in conjunction with the other two groups of reflective plates, a swirling wind field can be formed in the circumferential direction close to the third water trough 3, and in conjunction with the setting position of the protrusion 8 and the drainage trough 6, it is convenient to accelerate the discharge of condensed water from the third drainage trough 3 to the first water trough 1 or the second water trough 2; the third is that a certain swirl effect can also be formed around the flange 7 to help the condensed water fall and avoid the formation of a water film.

[0054] This embodiment preferably adopts the second processing method, referring to Figure 1 to Figure 2 As shown, 7. The reflective plates 5 processed in the second manner are provided with at least four groups, two of which are located on the leeward side of the flange 7, and the other two are located on the windward side of the flange 7;

[0055] The four groups of reflection plates 5 have the same structure and are distributed in a ring array relative to the flange 7 .

[0056] The second processing method has three advantages. The first is that the processing is convenient. Direct cutting, such as laser cutting, is more efficient and faster. At the same time, compared with processes such as bending and stamping, the probability of defective products produced by cutting is relatively low. Second, four groups of reflective plates 5 are cut. In actual use, the reflective plates 5 on the leeward side can be folded up for use, and the other two groups of reflective plates 5 on the windward side can be left unfolded. In addition, the reflective plates 5 on the windward side can also be selectively folded at the bottom height to achieve the effect of the first processing method mentioned above.

[0057] Third, the reflector 5 processed in this way is a sheet structure, which is heated more evenly during the heat conduction process. Because the reflector 5 also has a temperature difference problem between the windward side and the leeward side, but the simple arc-shaped sheet structure can largely avoid the problem of temperature difference deformation. Based on this, the reflector 5 is designed to be an arc structure, and the curvature of the reflector 5 is between π / 6-π / 4.

[0058] Regarding the number of reflectors 5, if there are too many circular arrays, noise will be generated and a more obvious wind blocking effect will occur. Figure 1 and Figure 2 The number shown is 2 groups on the leeward side, and 2 groups if set on the windward side. And they are set in the side area of ​​the flange 7, avoiding appearing in the horizontal central area of ​​the flange 7 to ensure smooth heat dissipation.

[0059] Finally, in the design of the present invention, another reflector 5 structure is designed taking into account some relatively large fins, especially when the flange 7 has a larger diameter and a higher height. Figure 3 and Figure 4 Each set of reflective plates 5 includes a guide plate 52 and a radiation plate 51 that are spaced apart from each other, and the tangent direction of the radiation plate 51 is parallel to the tangent direction of the outer periphery of the flange 7 that the radiation plate 51 faces, or forms an angle less than 10°;

[0060] The tangent direction of the guide plate 52 and the tangent direction of the radiation plate 51 form an angle between 20° and 50°, that is, Figure 4 The angle a in

[0061] The arc length of the radiation plate 51 is between 1 and 1.5 times the arc length of the guide plate 52. The radiation plate 51 and the guide plate 52 have at least 2 mm of overlapped portions. Figure 4 The distance b in .

[0062] Reference Figure 3As shown, in this structural design, the guide plate 52 and the radiation plate 51 form a rotary cutting relationship. It can rectify the wind field around the opening 7, better form a swirl effect, help the opening 7 to have a uniform temperature around the opening 7, and help discharge condensed water. At the same time, it is also beneficial for the guide plate 52 and the radiation plate 51 to receive wind evenly on both sides, avoiding temperature differences. In addition, in actual applications, this structure is less noisy than the aforementioned Figure 1 , Figure 2 The solution shown is smaller.

[0063] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
