Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat dissipation strip application technology, and in particular to a segmented spliced aluminum alloy heat dissipation strip. Background Technology
[0002] In fields such as electronic and mechanical equipment, heat dissipation is crucial. Aluminum alloy heat sinks are widely used in various heat dissipation scenarios due to their excellent thermal conductivity and light weight. However, most existing aluminum alloy heat sinks are one-piece structures, which presents several inconveniences in practical use.
[0003] On the one hand, integrated heat sinks are prone to deformation and damage during transportation and installation due to their long length, and they are also difficult to install, requiring professional installation tools and advanced installation skills.
[0004] On the other hand, when a part of the heat sink is damaged, the entire heat sink needs to be replaced, which increases the cost of use and the difficulty of maintenance. In addition, different usage scenarios have different requirements for the length of the heat sink, and the integral heat sink is difficult to meet diverse needs.
[0005] Therefore, this utility model proposes a segmented splicing aluminum alloy heat sink. Utility Model Content
[0006] The technical problem to be solved by this utility model is to provide a segmented splicing aluminum alloy heat sink to solve the problems of inconvenient transportation and installation, high replacement cost after damage, and difficulty in meeting diverse length requirements of existing integral aluminum alloy heat sinks.
[0007] To solve the above technical problems, the present invention adopts a technical solution as follows: a segmented splicing aluminum alloy heat sink is provided, including a base, wherein the aluminum alloy heat sink can be spliced sequentially along the length direction of the base, and each end of the base is provided with a matching splicing structure.
[0008] The surface of the base is fixedly connected with multiple heat dissipation fins, which are distributed perpendicular to the length direction of the base and are arranged at equal intervals.
[0009] The present invention is further configured such that mounting feet are symmetrically fixedly connected to the two side walls of the base near the corners.
[0010] The above technical solution facilitates accurate positioning and fixation of aluminum alloy heat sinks using mounting feet.
[0011] The present invention is further configured such that: the base has multiple air ducts evenly distributed inside, and each of the multiple air ducts can be filled with thermally conductive silicone.
[0012] With the above technical solution, the internal high temperature can be quickly discharged through the air duct when thermally conductive silicone is not used. When thermally conductive silicone is used, the absorbed temperature can be quickly transferred to the heat dissipation fins on the top for rapid heat dissipation.
[0013] The present invention is further configured such that: the splicing structure includes a recess at one end of the base and a convex part at the other end, wherein the shape and size of the recess and the convex part are adapted to each other;
[0014] The inner top and inner bottom of the concave portion are symmetrically fixedly connected with spring pieces, and the top and bottom of the convex portion are symmetrically provided with slots, and the spring pieces are engaged and connected to the slots.
[0015] Through the above technical solution, when splicing aluminum alloy heat sinks, two aluminum alloy heat sinks are pressed against each other through the concave and convex parts on their bases, so that the slots set on the convex parts are engaged with the spring pieces set inside the concave parts. In this way, the elasticity of the spring pieces can be used to strengthen the firmness of the adjacent spliced aluminum alloy heat sinks.
[0016] The present invention is further configured such that the spring sheet is open and has an arc-shaped bending portion.
[0017] The above technical solution facilitates the locking and fixing of two aluminum alloy heat sinks by using the arc-shaped spring clips during splicing, and allows for the sliding disassembly of adjacent aluminum alloy heat sinks during later disassembly.
[0018] The present invention is further configured such that all of the heat dissipation fins are plate-shaped and are installed on the base surface at a position that is offset from the position of the multiple air ducts.
[0019] The above technical solution facilitates the rapid transfer of high temperatures from both sides of the air duct to the heat dissipation fins at the top, thereby enabling the high temperatures to dissipate quickly after conduction.
[0020] The present invention is further configured such that triangular reinforcement portions are provided on both sides of the connection between the plurality of heat dissipation fins and the surface of the base.
[0021] The above technical solution facilitates the use of reinforcement components to fix the installation positions of multiple heat dissipation fins, ensuring their stability during use.
[0022] The beneficial effects of this utility model are as follows:
[0023] 1. This utility model solves the problem of inconvenient transportation and installation of integral heat sinks by splicing multiple aluminum alloy heat sink units. During transportation, the heat sink units can be transported separately, reducing the risk of deformation and damage to the heat sinks during transportation; during installation, an appropriate number of heat sink units can be selected and spliced according to actual needs, making the installation process simple and convenient, reducing the installation difficulty and the requirements for installation technology;
[0024] 2. By splicing the components together, this utility model allows for easy replacement of only the damaged aluminum alloy heat sink unit when a part is damaged, eliminating the need for complete replacement and significantly reducing usage costs and maintenance difficulty.
[0025] 3. This utility model can flexibly adjust the length of the heat dissipation strip according to different usage scenarios and heat dissipation requirements. By increasing or decreasing the number of aluminum alloy heat dissipation strip units, it can meet diverse usage needs. Attached Figure Description

[0033] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0034] like Figure 1 and Figure 2As shown, a segmented aluminum alloy heat sink includes a base 1. Mounting feet 11 are symmetrically fixed to the two side walls of the base 1 near the corners, facilitating accurate positioning of the aluminum alloy heat sink during installation. The aluminum alloy heat sink can be sequentially spliced along the length of the base 1. Multiple air ducts 12 are evenly distributed inside the base 1, and each air duct 12 can be filled with thermally conductive silicone. When thermally conductive silicone is not used, the air ducts 12 can quickly dissipate the internal high temperature. When thermally conductive silicone is used, the absorbed temperature can be quickly transferred to the top heat dissipation fins 2 for rapid heat dissipation.
[0035] like Figures 1-6 As shown, each base 1 has a matching splicing structure at both ends. The splicing structure includes a recess 13 at one end of the base 1 and a protrusion 14 at the other end. The shape and size of the recess 13 and the protrusion 14 are compatible with each other, so that when the aluminum alloy heat sink is installed, the protrusion 14 at its end face can be inserted into the recess 13 to achieve splicing and fixing of the two aluminum alloy heat sinks.
[0036] The inner top and bottom of the recess 13 are symmetrically fixed with spring pieces 131. The spring pieces 131 are open and have arc-shaped bends, which facilitates the locking and fixing of two aluminum alloy heat sinks when they are spliced by pressing them together. In addition, the two adjacent aluminum alloy heat sinks can be slidably disassembled during disassembly. The top and bottom of the protrusion 14 are symmetrically provided with slots 141, and the spring pieces 131 are engaged with the slots 141. When splicing the aluminum alloy heat sinks, the two aluminum alloy heat sinks are pressed against each other by the recess 13 and the protrusion 14 on their base 1, so that the slots 141 on the protrusion 14 are engaged with the spring pieces 131 inside the recess 13. The elasticity of the spring pieces 131 is used to strengthen the firmness of the adjacent spliced aluminum alloy heat sinks.
[0037] like Figure 2 As shown, multiple heat dissipation fins 2 are fixedly connected to the surface of the base 1. The multiple heat dissipation fins 2 are all plate-shaped and are installed on the surface of the base 1 in a staggered manner with the multiple air ducts 12. This allows the high temperature on both sides of the air ducts 12 to be quickly transferred to the heat dissipation fins 2 on the top, thus facilitating the rapid dissipation of the conducted high temperature. The multiple heat dissipation fins 2 are distributed perpendicular to the length direction of the base 1 and are arranged at equal intervals. Triangular reinforcement parts 21 are provided on both sides of the connection between the multiple heat dissipation fins 2 and the surface of the base 1. During use, the reinforcement parts 21 can be used to fix the installation position of the multiple heat dissipation fins 2, ensuring their firmness during use.
[0038] In use, the two aluminum alloy heat sinks are pressed against each other by the concave portion 13 and the convex portion 14 provided on the end face of the base 1. The convex portion 14 compresses and deforms the spring piece 131. When it corresponds to the slot 141, the spring piece 131 returns to its elastic state and engages with the inside of the slot 141, thus splicing and fixing the two aluminum alloy heat sinks. When disassembly is required later, the two aluminum alloy heat sinks need to be pushed and slid out in a mutually distancing manner to complete the disassembly of the aluminum alloy heat sinks.
[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
