Description

Technical Field

[0001] This utility model relates to the field of heat dissipation strip application technology, and in particular to a thin-walled aluminum alloy heat dissipation strip with anti-deformation support ribs. Background Technology

[0002] During the operation of power equipment, internal electronic components, windings, or power modules continuously generate heat. If the heat cannot be dissipated in time, the equipment temperature will rise, thereby reducing insulation performance, shortening service life, and even causing equipment failure.

[0003] Currently, thin-walled aluminum alloy heat sinks have become the mainstream heat dissipation components in electronic devices due to their light weight, high thermal conductivity, and moderate cost. However, existing products have the following key technical defects: insufficient connection strength between the heat sink and the heat sink plate, poor overall deformation resistance, insufficient ease of installation and stability, and incomplete heat dissipation efficiency. Therefore, this utility model proposes a thin-walled aluminum alloy heat sink with anti-deformation support ribs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a thin-walled aluminum alloy heat sink with anti-deformation support ribs, which aims to solve the technical problems of existing thin-walled aluminum alloy heat sinks such as "easy breakage of connections, easy deformation, difficult installation, and poor heat dissipation".

[0005] To solve the above technical problems, the present invention adopts a technical solution as follows: a thin-walled aluminum alloy heat sink with anti-deformation support ribs is provided, including a heat sink plate. A plurality of heat sinks are fixedly connected along the length direction on one side of the heat sink plate. An integrated reinforcing part is provided on the opposite side of two adjacent heat sinks near the bottom to improve the connection strength between the heat sink and the heat sink plate. Multiple reinforcing strips are snapped onto the top of the multiple heat sinks to reinforce and stabilize the top of the multiple heat sinks.

[0006] The present invention is further configured such that: a plurality of reinforcing ribs are arranged at equal intervals along the width direction at the bottom of the heat sink, and the cross-section of the plurality of reinforcing ribs is semi-circular.

[0007] Through the above technical solution, the semi-circular reinforcing rib is integrally formed with the heat dissipation plate. Without increasing the overall thickness of the heat dissipation plate, the mechanical advantages of the semi-circular structure are utilized—the arc surface can disperse the stress generated by external pressure and its own weight, which significantly improves the bending stiffness and torsional performance of the heat dissipation plate and prevents the heat dissipation plate from denting or bending due to installation compression or equipment vibration. At the same time, compared with the planar structure, the arc surface of the semi-circular reinforcing rib increases the heat dissipation surface area at the bottom of the heat dissipation plate, which can help conduct the heat absorbed by the heat dissipation plate into the air, further improving the overall heat dissipation efficiency.

[0008] The present invention is further configured such that: the bottom of the heat sink is provided with symmetrical mounting grooves near both sides, and both mounting grooves are L-shaped.

[0009] Through the above technical solutions, the L-shaped mounting groove can be precisely matched with the L-shaped mounting brackets or standard fasteners on the power equipment, and the heat sink can be quickly positioned and installed without drilling holes in the thin-walled heat sink plate. The symmetrically arranged mounting grooves can ensure that the heat sink is evenly stressed after installation, preventing the heat sink from shifting due to unilateral stress and not fitting tightly with the heat sink surface of the equipment. At the same time, the groove structure can limit the displacement of the heat sink in the horizontal and vertical directions, improving the stability after installation.

[0010] The present invention is further configured such that the cross-sections of the plurality of reinforcing parts are all provided with toothed grooves.

[0011] Through the above technical solution, the toothed groove structure has a dual function: on the one hand, the toothed protrusions can enhance the structural strength of the reinforcing part itself, further disperse the stress at the connection between the heat sink and the heat plate, avoid cracking at the connection due to thermal expansion and contraction, and strengthen the connection stability between the heat sink and the heat plate; on the other hand, the gap between the toothed grooves can form a longitudinal air circulation channel, promote air convection between adjacent heat sinks, accelerate the dissipation of heat on the surface of the heat sink, and achieve the synergistic effect of "structural reinforcement" and "assisted heat dissipation".

[0012] The present invention is further configured such that: the top of each of the multiple heat sinks is provided with multiple slots, and the heat sinks are engaged with the reinforcing strip through the slots.

[0013] Through the above technical solution, the snap-fit ​​connection between the slot and the reinforcing strip can connect multiple heat sinks that were originally arranged independently into a whole structure, avoiding individual heat sinks from tilting or bending due to airflow impact, equipment vibration or temperature changes; the snap-fit ​​connection does not require additional fasteners, will not damage the thin-walled structure of the heat sink, and is easy to disassemble. The number of reinforcing strips can be adjusted according to heat dissipation requirements to adapt to different heat sink lengths and usage scenarios.

[0014] The present invention is further configured such that: a stop block is fixedly connected to the bottom of the reinforcing strip and to both sides of the heat sink, and each set of the stop blocks is clamped in the slot of the heat sink.

[0015] Through the above technical solution, the baffle and the reinforcing strip are integrally formed, clamping and fixing the slot from both sides of the heat sink. This can limit the lateral displacement between the reinforcing strip and the heat sink, preventing them from loosening or separating due to long-term vibration of the equipment. At the same time, the clamping force of the baffle is evenly applied to the slot position of the heat sink, preventing local compression deformation of the thin-walled structure of the heat sink, further ensuring the structural integrity and reinforcement effect of the heat sink.

[0016] The present invention is further configured such that: a plurality of through-holes are uniformly opened on the surface of the heat sink, and the heat sinks are arranged in a matrix along the height direction of the heat sink.

[0017] Through the above technical solutions, the through-hole heat dissipation can significantly increase the effective heat dissipation surface area of ​​the heat sink and increase the probability of heat contact with air; the matrix arrangement can form an orderly airflow channel, allowing air to pass through the heat dissipation holes from one side of the heat sink to the other side, accelerating the airflow speed on the surface of the heat sink and reducing heat accumulation; in addition, the heat dissipation holes can also reduce the amount of material used in the heat sink, further reducing the overall weight of the heat dissipation strip while ensuring heat dissipation performance, meeting the lightweight requirements of thin-walled structures.

[0018] The beneficial effects of this utility model are as follows: 1. The thin-walled aluminum alloy heat sink with anti-deformation support rib proposed in this utility model improves the anti-deformation ability from three key positions: the bottom reinforcement of the heat sink, the bottom reinforcement of the heat sink plate, and the top reinforcement of the heat sink through a triple reinforcement structure. This effectively solves the problems of easy cracking, easy tilting, and easy bending of traditional thin-walled heat sinks. 2. The thin-walled aluminum alloy heat sink with anti-deformation support ribs proposed in this utility model improves heat dissipation efficiency while strengthening the structure through the synergistic design of toothed groove air channels and matrix through heat dissipation holes. Compared with traditional solid thin-walled heat sinks, the heat dissipation efficiency is improved, which can meet the heat dissipation requirements of high-power electrical equipment. At the same time, the L-shaped mounting groove design simplifies the installation process, avoids structural damage, and improves installation efficiency, taking into account practicality and economy.

[0021] 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.

[0022] like Figure 1 and Figure 2 As shown, a thin-walled aluminum alloy heat sink with anti-deformation support ribs includes a heat sink 1. Multiple reinforcing ribs 11 are equidistantly arranged along the width direction at the bottom of the heat sink 1, and the cross-section of each reinforcing rib 11 is semi-circular. The semi-circular reinforcing ribs 11 are integrally formed with the heat sink 1. Without increasing the overall thickness of the heat sink 1 and maintaining its thin-walled characteristics, the mechanical advantages of the semi-circular structure—the arc surface can disperse the stress generated by external pressure and its own weight—significantly improve the bending stiffness and torsional performance of the heat sink 1, preventing dents and bends caused by installation compression or equipment vibration. Simultaneously, compared to a planar structure, the arc surface of the semi-circular reinforcing ribs 11 increases the heat dissipation surface area at the bottom of the heat sink 1, which can help conduct the heat absorbed by the heat sink 1 into the air, further improving the overall heat dissipation efficiency. The bottom of the heat sink 1 is symmetrically provided with mounting slots 12 near both sides, and both mounting slots 12 are L-shaped. The L-shaped mounting slots 12 can be precisely matched with L-shaped mounting brackets or standard fasteners such as L-shaped buckles and corner brackets on the power equipment. There is no need to drill holes in the thin-walled heat sink 1, which avoids drilling damage to the thin-walled structure and stress concentration, and can realize the rapid positioning and installation of the heat sink. The symmetrical mounting slots 12 can ensure that the heat sink is evenly stressed after installation, preventing the heat sink from shifting due to unilateral stress and not fitting tightly with the heat dissipation surface of the equipment. At the same time, the slot structure can limit the displacement of the heat sink in the horizontal and vertical directions, improving the stability after installation.

[0023] like Figure 3 and Figure 4 As shown, a plurality of heat sinks 2 are fixedly connected along the length of one side of the heat sink 1. An integrated reinforcing part 21 is provided near the bottom of the opposite surface of each adjacent heat sink 2 to enhance the connection strength between the heat sink 2 and the heat sink 1. The cross-section of each reinforcing part 21 is a toothed groove. The toothed groove structure has a dual function: firstly, the toothed protrusions enhance the structural strength of the reinforcing part 21 itself, further dispersing the stress at the connection between the heat sink 2 and the heat sink 1, preventing cracking due to thermal expansion and contraction, and strengthening the connection stability between the heat sink 2 and the heat sink 1; secondly, the gaps between the toothed grooves form a longitudinal airflow channel, promoting air convection between adjacent heat sinks 2, accelerating the dissipation of heat from the surface of the heat sink 2, and achieving a synergistic effect of "structural reinforcement" and "auxiliary heat dissipation." Multiple heat sinks 2 are provided with multiple slots 22 on their tops, and are connected to the reinforcing strips 3 by engaging with the reinforcing strips 3 through the slots 22. The engaging connection between the slots 22 and the reinforcing strips 3 can connect multiple heat sinks 2 that were originally arranged independently into a whole structure, preventing individual heat sinks 2 from tilting or bending independently due to airflow impact, equipment vibration or temperature changes. The engaging connection does not require additional fasteners such as screws or rivets, will not damage the thin-walled structure of the heat sinks 2, and is easy to disassemble. The number of reinforcing strips 3 can be adjusted according to the heat dissipation requirements, such as setting 1-3 reinforcing strips along the length of the heat sink, to adapt to different heat sink lengths and usage scenarios. Multiple through-holes 23 are evenly distributed on the surface of the heat sink 2, and the heat sink 23 are arranged in a matrix along the height direction of the heat sink 2. The through-holes 23 can significantly increase the effective heat dissipation surface area of ​​the heat sink 2 and increase the probability of heat contact with air. The matrix arrangement can form an orderly airflow channel, and air can pass through the heat sink 2 through the heat sink 2 to the other side, accelerating the airflow speed on the surface of the heat sink 2 and reducing heat accumulation. In addition, the heat sink 23 can also reduce the amount of material used in the heat sink 2, and further reduce the overall weight of the heat sink while ensuring heat dissipation performance, which meets the lightweight requirements of thin-walled structures.

[0024] like Figure 4 and Figure 5 As shown, multiple reinforcing strips 3 are engaged at the top of multiple heat sinks 2 to reinforce and stabilize the top of the heat sinks 2. Each reinforcing strip 3 has a stop 31 fixedly connected to its bottom and on both sides of the heat sink 2. Each set of stop blocks 31 clamps into the slot 22 of the heat sink 2. The stop blocks 31 and reinforcing strips 3 are integrally formed, clamping and fixing the slot 22 from both sides of the heat sink 2. This restricts lateral displacement between the reinforcing strips 3 and the heat sink 2, preventing loosening or detachment due to long-term equipment vibration. Simultaneously, the clamping force of the stop blocks 31 is evenly applied to the slot 22 of the heat sink 2, preventing localized compression deformation of the thin-walled structure of the heat sink 2, further ensuring the structural integrity and reinforcement effect of the heat sink 2.

[0025] In use, this invention first achieves precise positioning and tight fit between the heat sink and the heat dissipation surface of the power equipment through the L-shaped mounting grooves 12 symmetrically arranged near the bottom of the heat sink 1, ensuring that the heat generated by the equipment can be efficiently conducted to the heat sink 1. The heat is further conducted to multiple heat sinks 2 equidistantly arranged along the length of one side of the heat sink 1. The matrix-style through-holes 23 evenly opened on the surface of the heat sink 2 can significantly increase the heat dissipation surface area and accelerate the contact and exchange of heat with the air. At the same time, the integrated toothed groove reinforcement 21 extending along the height direction near the bottom of the opposite surface of the adjacent heat sink 2 can not only disperse the stress at the connection between the heat sink 2 and the heat sink 1 to avoid cracking, but also form a longitudinal... Air circulation channels assist in convection heat dissipation; in addition, the semi-circular reinforcing ribs 11 arranged at equal intervals along the width direction at the bottom of the heat sink 1 can improve the bending stiffness of the heat sink 1 while maintaining the thin-wall characteristics, preventing it from denting and deforming due to force or its own weight. The tops of multiple heat sinks 2 are engaged with the reinforcing strips 3 through slots 22, and the blocks 31 at the bottom of the reinforcing strips 3 located on both sides of the heat sink 2 form a clamping and fixing of the slots 22, which can connect the dispersed heat sinks 2 into a whole to avoid tilting. Finally, while ensuring the stability of the heat dissipation structure with multiple anti-deformation structures, the efficient conduction and dissipation of heat from the power equipment to the air are achieved.
