Description

Technical Field

[0001] The present application relates to the field of heat dissipation devices, and in particular to an aluminum profile heat dissipation device. Background Art

[0002] In electronic equipment, mechanical equipment, and industrial manufacturing, heat dissipation is a key factor affecting device stability and service life. With the continuous advancement of technology, device integration is increasing, and power density is also increasing, leading to a sharp increase in heat generation. Therefore, how to effectively dissipate the heat generated within the device to prevent performance degradation or even damage caused by overheating has become a pressing issue.

[0003] Traditional cooling methods often use fans, heat pipes, or heat sinks, but these methods often suffer from low cooling efficiency, bulk, high cost, or complex installation. Finding an efficient and compact cooling solution is particularly important in applications where high cooling efficiency is required and space is limited, such as LED lighting, communications equipment, and industrial control cabinets.

[0004] Aluminum extrusions are widely used in heat dissipation design due to their excellent thermal conductivity, light weight, ease of processing, and corrosion resistance. However, traditional aluminum extrusion heat dissipation devices often have a simple structure and poorly designed heat dissipation channels, resulting in limited heat dissipation efficiency and difficulty meeting the heat dissipation requirements of modern high-power density equipment. Utility Model Content

[0005] The purpose of this application is to provide an aluminum profile heat dissipation device, which aims to significantly improve the heat dissipation efficiency through a unique multi-layer heat dissipation groove design and symmetrical layout, while maintaining the compactness and aesthetics of the structure, providing an effective heat dissipation solution for modern high-power density equipment.

[0006] In order to achieve the above objectives, this application provides the following technical solutions:

[0007] An aluminum profile heat dissipation device includes an aluminum profile body, which is N-shaped. The lower part of the aluminum profile body has a first heat dissipation groove, and the first heat dissipation groove has an opening arranged downward. The aluminum profile body is symmetrically distributed left and right and is sequentially provided with a second heat dissipation groove, a third heat dissipation groove, a fourth heat dissipation groove and a fifth heat dissipation groove from top to bottom. A sixth heat dissipation groove is provided at the symmetry axis in the middle of the aluminum profile body. The upper surface of the aluminum profile body is symmetrically provided with first grooves downwardly, and the upper wall of the second heat dissipation groove is provided with a protrusion downwardly. The first heat dissipation groove, the second heat dissipation groove, the third heat dissipation groove, the fourth heat dissipation groove and the fifth heat dissipation groove all extend along the length direction of the aluminum profile body.

[0008] Furthermore, a second heat dissipation arc portion is provided on a lower corner of the second heat dissipation groove close to the symmetry axis of the aluminum profile body, and the second heat dissipation arc portion is bent upward.

[0009] Furthermore, a third heat dissipation arc portion is provided at a lower corner of the third heat dissipation groove close to the symmetry axis of the aluminum profile body, and the third heat dissipation arc portion is bent upward.

[0010] Furthermore, a fourth heat dissipation arc portion is provided at an upper corner of the fourth heat dissipation groove close to the symmetry axis of the aluminum profile body, and the fourth heat dissipation arc portion is bent downward.

[0011] Furthermore, a fifth heat dissipation arc portion is provided at a lower corner of the fifth heat dissipation groove away from the symmetry axis of the aluminum profile body, and the fifth heat dissipation arc portion is bent upward.

[0013] Furthermore, a second wavy heat dissipation protrusion is provided on the right side of the aluminum profile body, and the second heat dissipation protrusion is respectively located at the upper part and the lower part of the aluminum profile body.

[0014] The beneficial effects of this application are:

[0015] (1) This application designs multiple heat dissipation slots (the first to fifth heat dissipation slots, and the sixth heat dissipation slot located in the middle) on the aluminum profile body. These heat dissipation slots extend along the length of the aluminum profile body, forming a rich heat dissipation path.

[0022] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0023] This embodiment provides an aluminum profile heat sink, primarily used to improve the heat dissipation efficiency of high-heat source components (Q) such as electronic equipment and mechanical equipment. The heat sink primarily comprises an aluminum profile body 1, made of a high-quality aluminum alloy with excellent thermal conductivity and workability. During heat dissipation, the high-heat source components are positioned on the sides of the aluminum profile heat sink.

[0024] An aluminum profile heat dissipation device includes an aluminum profile body 1. The aluminum profile body 1 is designed in an N-shape as a whole. This design is not only beautiful and elegant, but also can effectively utilize space and enhance the heat dissipation effect. The length, width and height of the aluminum profile body 1 can be customized according to the specific application scenario to meet the heat dissipation requirements of different equipment. The lower part of the aluminum profile body 1 has a first heat dissipation groove 2. The first heat dissipation groove 2 is located in the lower part of the aluminum profile body 1 and has an opening a set downward. This opening design is conducive to guiding cold air to enter from below, forming natural convection and improving heat dissipation efficiency. The left and right sides of the aluminum profile body 1 are distributed along the symmetry axis W and are sequentially provided with a second heat dissipation groove 3, a third heat dissipation groove 4, a fourth heat dissipation groove 5 and a fifth heat dissipation groove 6 from top to bottom. These four heat dissipation grooves are symmetrically distributed on the left and right sides of the aluminum profile body 1 and arranged in sequence from top to bottom. They all extend along the length of the aluminum profile body 1, forming multiple parallel heat dissipation channels, effectively increasing the heat dissipation area. A sixth heat dissipation groove 7 is provided at the symmetry axis in the middle of the aluminum profile body 1. The sixth heat dissipation groove 7 is located at the symmetry axis in the middle of the aluminum profile body 1, further enhancing the heat dissipation effect. The design of this groove also takes into account the balance of structural strength, avoiding structural weakening caused by too many heat dissipation grooves. The upper surface of the aluminum profile body 1 is symmetrically provided with first grooves 8 downwardly, and the upper wall of the second heat dissipation groove 3 is provided with a protrusion 9 downwardly. The first heat dissipation groove 2, the second heat dissipation groove 3, the third heat dissipation groove 4, the fourth heat dissipation groove 5 and the fifth heat dissipation groove 6 all extend along the length of the aluminum profile body 1. The design of this protrusion 9 is intended to optimize the air flow path, guide the hot air to flow upward, and discharge it through other heat dissipation grooves, thereby further improving the heat dissipation efficiency.

[0025] Tooling principle: When the equipment is running, the heat generated is transferred to the aluminum profile body 1 through thermal conduction. Because the aluminum profile body 1 is provided with multiple heat dissipation slots, the heat can be quickly dispersed to each channel. At the same time, the downward opening design of the first heat dissipation slot 2 guides cold air in from below, forming convection with the hot air and accelerating heat dissipation. The parallel arrangement of the second to fifth heat dissipation slots 6 and the sixth heat dissipation slot 7 further increases the heat dissipation area and heat dissipation path, allowing heat to be dissipated to the surrounding environment more efficiently.

[0026] In this embodiment, a second heat dissipation arc 31 is provided at the lower corner of the second heat dissipation slot 3, near the axis of symmetry of the aluminum profile body 1. This arc 31 is curved upward. This arc is designed to guide air flow, forming localized vortices, thereby increasing the contact time and area between the air and the heat dissipation surface, improving heat dissipation efficiency. This arc also enhances the aesthetics of the heat sink, making the overall design more streamlined.

[0027] In this embodiment, the third heat dissipation channel 4 is provided with a third heat dissipation arc portion 41 at the lower corner near the axis of symmetry of the aluminum profile body 1. The third heat dissipation arc portion 41 is curved upward. This design not only complements the second heat dissipation arc portion 31 to form an integrated heat dissipation airflow guidance system, but also further enhances the heat dissipation capacity of the third heat dissipation channel 4. By properly controlling the size and curvature of the arc portion, the air flow path can be optimized and heat dissipation efficiency can be improved.

[0028] In this embodiment, the fourth heat dissipation slot 5 is provided with a fourth heat dissipation arc portion 51 at an upper corner near the axis of symmetry of the aluminum profile body 1. The fourth heat dissipation arc portion 51 is bent downward. In this embodiment, the fifth heat dissipation slot 6 is provided with a fifth heat dissipation arc portion 61 at a lower corner away from the axis of symmetry of the aluminum profile body 1. The fifth heat dissipation arc portion is bent upward.

[0029] In this embodiment, the left side of the aluminum profile body 1 is provided with a first wave-shaped heat dissipation protrusion 101. These protrusions improve heat exchange efficiency by increasing surface area and redirecting air flow. The wave-shaped design also enhances the heat sink's mechanical strength and resistance to deformation.

[0030] In this embodiment, the right side of the aluminum profile body 1 is provided with a wavy second heat dissipation projection 102, located at the upper and lower portions of the aluminum profile body 1. These projections, located at the upper and lower portions of the aluminum profile body 1, complement the first heat dissipation projection 101 on the left side, together forming a comprehensive, multi-layered heat dissipation system. The provision of the second heat dissipation projection 102 not only increases the heat dissipation area, but also, through its unique shape, guides air flow, forming a more efficient heat dissipation airflow channel.
