Description

Technical Field

[0001] This utility model relates to the field of radiator technology, specifically to an aluminum profile for radiators. Background Technology

[0002] Aluminum radiator profiles, also known as aluminum profile radiators, are widely used due to their attractive appearance, light weight, and good heat dissipation performance. They consist of a base and heat dissipation fins mounted on the base. However, the individual heat dissipation fins in existing aluminum radiator profiles have relatively poor strength and are easily bent. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of this utility model is to provide an aluminum profile for heat sinks to solve or alleviate the above-mentioned technical problems in the prior art.

[0004] To achieve the above objectives, this utility model provides an aluminum profile for a heat sink, including a profile body, on which a plurality of heat sink fins are provided, and on which a plurality of reinforcing portions are provided to enhance the strength of the heat sink fins. The plurality of reinforcing portions are arranged sequentially at intervals along the width direction of the heat sink fins, and the length direction of the reinforcing portions extends along the length direction of the heat sink fins.

[0005] Furthermore, the multiple reinforcing portions on any two adjacent heat dissipation fins are staggered.

[0006] Furthermore, the distance between any two adjacent heat dissipation fins is less than or equal to the width of the reinforcing portion.

[0007] Furthermore, the reinforcing part is provided with ventilation holes for cooling air to pass through.

[0008] Furthermore, the sidewall thickness of the ventilation hole is equal to the thickness of the heat dissipation fins.

[0009] Furthermore, the cross-section of the reinforcing part is circular or polygonal.

[0010] Furthermore, it also includes connecting rods, which sequentially pass through all the heat dissipation fins and are movably connected to the heat dissipation fins. Multiple connecting rods are provided, and the multiple connecting rods are sequentially spaced along the length direction of the heat dissipation fins.

[0011] Each of the connecting rods is fitted with multiple limiting rings, and the multiple limiting rings and multiple heat dissipation fins are arranged alternately in sequence, with the end of the limiting ring abutting against the side wall of the heat dissipation fin.

[0012] The beneficial effects of this utility model are:

[0013] The aluminum profile for heat sinks provided by this utility model improves the strength of individual heat sink fins by setting reinforcing parts on the heat sink fins, and at the same time increases the contact area between the heat sink fins and the air, thereby improving heat dissipation efficiency.

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0026] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0028] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0030] like Figure 1-7As shown, this utility model provides an aluminum profile for a heat sink, including a profile body 110. The profile body 110 has multiple heat dissipation fins 120, and each heat dissipation fin 120 has multiple reinforcing portions 130 to enhance its strength. The reinforcing portions 130 are spaced apart sequentially along the width direction of the heat dissipation fins 120, and their length direction extends along the length direction of the heat dissipation fins 120. Furthermore, by adding the reinforcing portions 130, the contact area between the heat dissipation fins 120 and the air can be increased, thereby improving the heat dissipation effect.

[0031] Since the reinforcing part 130 protrudes from the heat dissipation fins 120, in order to reduce the spacing between heat dissipation fins 120 while maintaining the spacing between adjacent heat dissipation fins 120, more heat dissipation fins 120 can be provided, thereby improving the heat dissipation effect. Therefore, as Figure 1-7 As shown, in this embodiment, multiple reinforcing parts 130 on any two adjacent heat dissipation fins 120 are staggered.

[0032] Optionally, the distance between any two adjacent heat dissipation fins 120 is less than or equal to the width of the reinforcing portion 130. It should be noted that the width of the reinforcing portion 130 refers to the distance between the opposite sides of the reinforcing portion 130. When the reinforcing portion 130 is circular, the width of the reinforcing portion 130 is the outer diameter of the reinforcing portion 130.

[0033] like Figure 2 , 4 As shown in Figures 5 and 6, a ventilation hole 140 for cooling air is provided at the reinforcing part 130. In the working state, the cooling air can not only pass through the surface of the heat dissipation fin 120 to carry away the heat on the heat dissipation fin 120, but also pass through the ventilation hole 140 to carry away the heat on the heat dissipation fin 120, so as to improve the heat dissipation effect.

[0034] Optionally, the sidewall thickness of the ventilation hole 140 is equal to the thickness of the heat dissipation fin 120, so that the heat dissipation of the heat dissipation fin 120 is more uniform.

[0035] like Figure 1-7 As shown, optionally, the cross-section of the reinforcing part 130 is circular or polygonal. Since polygons have better bending resistance, it is preferable that the cross-section of the reinforcing part 130 is polygonal.

[0036] like Figure 5-7 As shown, preferably, it also includes a connecting rod 150, which passes through all the heat dissipation fins 120 in sequence and is movably connected to the heat dissipation fins 120. Multiple connecting rods 150 are provided, and multiple connecting rods 150 are arranged at intervals along the length direction of the heat dissipation fins 120.

[0037] Multiple limiting rings 160 are fitted on any one of the connecting rods 150. The multiple limiting rings 160 and multiple heat dissipation fins 120 are arranged alternately in sequence, and the end of the limiting ring 160 abuts against the side wall of the heat dissipation fin 120.

[0038] Specifically, there are n heat dissipation fins 120 and m limiting rings 160 fitted on the connecting rod 150, where m and n are both positive integers greater than or equal to 2, and m = n + 1. The m limiting rings 160 and n heat dissipation fins 120 are alternately arranged. The two limiting rings 160 located at both ends of the connecting rod 150 are fixedly connected to the connecting rod 150, and the remaining limiting rings 160 are movably connected to the connecting rod 150. At least one limiting ring 160 located at one end of the connecting rod 150 is detachably connected to the connecting rod 150 (e.g., threaded connection) to facilitate the installation and removal of the connecting rod 150 and the limiting rings 160.

[0039] In this embodiment, all heat dissipation fins 120 are connected into a whole by the limiting ring 160 and the connecting rod 150, thereby enhancing their bending resistance.

[0040] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
