Description

Technical Field

[0001] The utility model relates to the field of radiators, in particular to a sunflower radiator aluminum profile. Background Art

[0002] With the continuous progress of science and technology and the improvement of people's living standards, various optoelectronic devices have been widely used in our daily life and work. However, in current life, there are some problems with common lamp light sources: in LED panel lights, 30% to 35% of the electrical energy of the chip is converted into light energy when it is working normally, and the other 65% to 70% is converted into heat energy. LED panel lights are very sensitive to temperature, and 70% of LED failures come from over-high temperature.

[0003] There are many types of radiator structures. Commonly used radiators have fins that are neatly arranged and evenly distributed on the surface of the cylindrical structure, but this design is not conducive to air flow, making it difficult to dissipate heat. In order to increase the heat dissipation speed and ensure uniform heat dissipation, it is necessary to improve the structure of the radiator and make the heat dissipation fin design more efficient: quickly dissipate heat, promote air flow, increase the heat dissipation area, and reduce the use of consumables.

[0004] CN209587998U discloses a novel sunflower radiator, comprising an integrally formed heat-conducting beam and a heat-dissipating rib group, wherein the heat-dissipating rib group comprises a plurality of first ribs, a plurality of second ribs, a third rib and a fourth rib uniformly distributed on the circumferential surface of the heat-conducting beam, a first groove is provided on the second rib body, a second groove is provided on the third rib body, the third rib and the fourth rib are symmetrically arranged on the heat-conducting beam, a straight horizontal edge is provided at the port of the first rib, an arc-shaped horizontal edge is provided at the ports of the second rib, the third rib and the fourth rib, the arc-shaped horizontal edges at the ports of the second rib, the third rib and the fourth rib are arranged on the same circle, and the first groove and the second groove have different shapes. The novel sunflower radiator increases the contact area with the air by cooperating with different grooves and heat-dissipating ribs, and at the same time changes the air flow direction to form a backflow, so as to achieve better heat dissipation.

[0005] Based on this, the technical problem solved in this case is: how to further optimize the structure of the sunflower radiator to solve the problems of uneven heat dissipation and slow response speed. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a sunflower radiator aluminum profile, the radiator has a firm structure, the fins are not easily deformed, the heat dissipation surface area can be increased, and uniform heat dissipation can be ensured everywhere.

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] See also Figure 1 A sunflower radiator aluminum profile includes a base 1, a plurality of fins 2, and four support ribs 3 arranged in a circular array around the base 1; the plurality of fins 2 are arranged in a circular array around the base 1; the top of the support rib 3 and the top of the fin 2 are on the same circumference; one end of the support rib 3 is connected to the base 1, and the other end of the support rib 3 extends outward and is provided with a gradually widened portion 4.

[0022] In this embodiment, the thickness of the supporting rib 3 is greater than that of the fin 2 .

[0023] The overall structure of this embodiment is an axisymmetric structure with multiple axes of symmetry, and the support ribs 3 can play a role in strengthening the overall strength, making the overall structure not easy to deform, while ensuring the heat dissipation performance and increasing the safety performance; one end of the support rib 3 is provided with a gradually widening portion 4. Compared with the traditional structure, the gradually widening design can make it easier for heat to be conducted to the gradually widening portion 4, thereby avoiding the problem of heat concentrated in the center of the radiator.

[0024] Specifically, the support ribs 3 are in the shape of square bars in the horizontal cross section.

[0025] As a preference of this embodiment, in order to achieve the above-mentioned technical effect, the gradually widening portion 4 of this embodiment is a structure that is wide at the top and narrow at the bottom in a horizontal cross section, and the narrow end coincides with the supporting rib 3 .

[0026] As a further preference of this embodiment, the gradually widening portion 4 includes a gradually widening section 41 connected to the support rib 3 and a smooth section 42 connected to the gradually widening section 41; in the horizontal cross section, the gradually widening section 41 gradually enlarges, and the smooth section 42 is a square strip. In this embodiment, this design is mainly to meet the installation requirements of the lighting product. It should be noted that in addition to the preference of this embodiment, in actual applications, other methods can also be used to achieve the gradually widening design, such as a design with only the gradually widening section 41 or a structure in which the entire support rib 3 is wide at the top and narrow at the bottom. Of course, when designing, attention should be paid to the relationship between its thickness and surface area to avoid affecting the effect of heat conduction.

[0027] In this embodiment, preferably, there are 16 fins 2, and the 16 fins 2 are evenly divided into four groups, and the four groups of fins 2 are respectively arranged between adjacent support ribs 3. In addition, the angle between two adjacent fins 2 is 14°; the angle between the support rib 3 and the adjacent fin 2 is 24°.

[0028] Under the above-mentioned optimization, the heat is evenly dissipated at all places of the radiator, thus avoiding the problem of heat concentration, achieving even heat distribution and better heat dissipation effect.

[0029] In this embodiment, in order to further increase the surface area for heat dissipation, a plurality of grooves 21 are arranged at equal intervals on both sides of the fin 2, which are wavy in shape in a horizontal cross section.
