Description

Technical Field

[0001] The utility model belongs to the field of radiator manufacturing, and in particular relates to a tooth plate extension structure of a radiator. Background Art

[0002] Radiators, as key components of heat exchange devices, are widely used in electronic devices to dissipate the heat generated by the electronic components inside the device during operation. The performance of radiators is directly related to the stable operation and service life of electronic equipment. With the rapid development of science and technology, especially in the fields of computers, communication equipment, automobiles, aerospace, etc., the performance requirements for radiators are getting higher and higher.

[0003] The heat dissipation performance of the fin heat sink mainly depends on its heat dissipation area, heat sink material, heat sink layout and heat dissipation duct design. The design of the heat dissipation duct is particularly critical, which directly affects the heat dissipation efficiency and the direction of heat transfer. A good heat dissipation duct design can ensure that heat is quickly and effectively transferred from the heat sink to the surrounding environment, thereby avoiding overheating of the equipment. Effective air flow is one of the key factors in improving heat dissipation efficiency. In many existing heat dissipation solutions, the design of the heat dissipation duct is particularly important for guiding and enhancing air flow. However, these ducts often cannot provide efficient heat dissipation performance and flexible installation options at the same time due to design limitations. Therefore, optimizing the heat dissipation duct structure to improve heat dissipation efficiency and adapt to diverse application environments has become an important technical challenge.

[0004] In addition, with the development of technology, the requirements for equipment performance are getting higher and higher, and accordingly, the demand for heat dissipation is also increasing. Especially in applications with limited space or high heat load, traditional fin heat sinks have limited heat dissipation capacity, fixed heat dissipation direction, and insufficient environmental adaptability.

[0005] The heat sink design of traditional fin heat sinks is relatively fixed, and the air duct structure is single, which leads to limited heat dissipation efficiency. Especially in high-power, high-density electronic devices, the heat dissipation effect is often difficult to achieve an ideal state. Secondly, the heat dissipation air duct is not directional enough and cannot be flexibly adjusted according to the actual application scenario, which limits the application scope of the heat sink to a certain extent.

[0006] Therefore, in order to overcome the shortcomings of existing radiators in the design of heat dissipation ducts, improve heat dissipation efficiency, and expand the scope of application, the utility model proposes a new type of heat sink extension structure for radiators. This structure not only achieves the extension of the heat sink and the increase of the heat dissipation area by connecting new heat sinks, but more importantly, ensures the efficient transfer and dissipation of heat by optimizing the layout of the heat sink and the design of the heat dissipation duct. Utility Model Content

[0007] The utility model aims to provide a tooth plate extension structure of a radiator to solve the technical problems of enhancing the heat dissipation effect and heat dissipation air duct of the radiator and adapting to different heat dissipation environments.

[0008] In order to achieve the above-mentioned purpose, the specific technical solution of the tooth plate extension structure of a radiator of the utility model is as follows:

[0009] A fin extension structure for a radiator, characterized in that it comprises a plurality of extension fins connected to the upper end of the radiator fin; the extension fins comprise a connecting end connected to the radiator fin, a supporting section connected to the connecting end, and an extension section connected to the supporting section at a certain connecting angle.

[0010] As a further improvement of the present invention, the connecting end includes a connecting portion abutting against the top end of the heat sink, and clamping portions arranged on both sides of the connecting portion abutting against both sides of the heat sink, the spacing between the clamping portions matches the width of the heat sink, and the clamping portions clamp the heat sink on both sides to achieve a stable connection between the extension piece and the heat sink.

[0011] As a further improvement of the utility model, the connection angles of the extension pieces connected to the same radiator are consistent.

[0012] As a further improvement of the present invention, the height of the support section increases or decreases successively along the distribution direction of the heat sink.

[0013] As a further improvement of the utility model, the extension piece is provided with protrusions and / or depressions to increase the heat dissipation surface area and provide more heat dissipation channels, thereby improving the heat dissipation effect.

[0014] As a further improvement of the present invention, the extension piece is in a special-shaped bending shape to increase the heat dissipation area.

[0015] As a further improvement of the utility model, ventilation grooves are provided on the surface of the extension pieces to allow air to pass through and form air flow between the extension pieces, thereby further improving the heat dissipation efficiency.

[0016] As a further improvement of the present invention, the connection angle is 90° to 180°.

[0017] As a further improvement of the present invention, the extension section extends outward from the side of the support section and forms a certain inclination angle with the horizontal plane.

[0018] As a further improvement of the present invention, the extension sheet and the heat sink are connected by welding, riveting, bonding or mechanical fastening.

[0019] Beneficial effects:

[0020] The tooth extension structure of the utility model effectively increases the heat dissipation area by connecting a number of extension pieces to the heat sink, thereby improving the heat dissipation efficiency. The extension piece is made of a material with good thermal conductivity, which can quickly conduct heat to the heat sink fins and take away the heat through air convection, thereby effectively reducing the temperature of the radiator. When the existing shovel-tooth radiator has a limited heat dissipation environment and cannot increase the heat dissipation area by extending the heat sink upward, the heat dissipation effect can be enhanced by extending it to the side.

[0021] The extension pieces with increasing heights in the support section form a gradient structure, which allows the heat to be more evenly distributed over the entire heat dissipation structure, avoiding local overheating. This gradient structure can also be flexibly adjusted according to the heat dissipation requirements to meet the heat dissipation requirements in different scenarios.

[0022] The connection angle between the extension section and the support section of the extension piece of the utility model enhances the guiding effect of air between the heat dissipation fins, forms an effective heat dissipation channel, reduces the resistance of air flow, and improves the effect of convective heat exchange. Through different connection angles, the extension piece can be flexibly adjusted according to the actual installation space and heat dissipation requirements. This design not only improves the adaptability of the radiator, but also reduces restrictions during the installation process.

[0023] The heat dissipation design on the extended fins not only increases the heat dissipation area, but also helps to form a uniform air flow between the heat sinks, thereby improving the heat dissipation uniformity and avoiding local overheating. This design can further improve the heat dissipation efficiency, allowing the radiator to maintain good heat dissipation performance even when running at high load.

[0024] To sum up, the tooth extension structure of a radiator of the utility model has the beneficial effects of high heat dissipation efficiency, strong adaptability, easy installation, stable operation, etc. The number, length, width, thickness, shape and layout of the extension plates can be flexibly optimized according to different heat dissipation requirements and equipment space limitations, so that the tooth extension structure of the radiator can adapt to a wide range of application scenarios while considering manufacturing costs and process feasibility.

[0029] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0030] Embodiment 1:

[0031] like Figure 1 As shown, a fin extension structure of a heat sink is designed to improve heat dissipation efficiency and heat dissipation area, thereby improving heat dissipation performance. It is composed of a plurality of extension pieces 100 installed on the top of a heat sink 210, and the extension piece 100 includes a connecting end 110, a supporting section 120, and an extension section 130 arranged in sequence.

[0032] The connection end is the connection part between the extension sheet 100 and the heat sink 210. The connection methods of the connection end 110 of the extension sheet 100 and the heat sink 210 include but are not limited to welding, riveting, bonding or mechanical fastening. In this embodiment, the connection end is in the shape of "П", including a connection part 111 abutting against the top of the heat sink 210, and clamping parts 112 arranged on both sides of the connection part 111 abutting against the two sides of the heat sink 210. The spacing between the two clamping parts 112 is slightly smaller than the width of the heat sink 210. The opening of the connection end 110 is aligned with the top of the heat sink 210 and pressed down. After the connection part 111 abuts against the top of the heat sink 210, the clamping parts 112 on both sides clamp and fix the two sides of the heat sink 210.

[0033] The support section 120 is erected on the upper end of the connection end 110 and gradually increases along one side of the heat sink 200 to the other side, which is convenient for the installation of the extension plate. The increase can be adjusted according to the spacing of the heat sink 210 and the heat dissipation requirements.

[0034] The extension section 130 is connected to the upper end of the support section 120 at a certain connection angle 140. The connection angle 140 can be adjusted according to the actual installation environment to adapt to the heat dissipation environment and improve the heat dissipation effect. The connection angle 140 of this embodiment is 90°, and the extension section 130 is connected to the upper end surface of the support section 120 at a uniform connection angle 140. The length, width, thickness, shape and layout of the extension section 130 are optimized according to the heat dissipation requirements and space limitations to ensure the optimal heat dissipation effect while taking into account the manufacturing cost and process feasibility. The extension section 130 can adopt a special-shaped bending structure such as a wave shape, a spiral shape or a fan shape to maximize the heat dissipation area.

[0035] The extension piece 100 is provided with protrusions and depressions on its surface, which can increase the heat dissipation surface area and provide more heat dissipation channels, such as heat dissipation fins, to form air turbulence between the extension pieces 100, thereby improving the heat dissipation effect. At the same time, the extension piece 100 is also provided with ventilation slots to allow air to pass through and form air flow between the heat dissipation fins, further improving the heat dissipation efficiency.

[0036] Embodiment 2:

[0037] like Figure 3 As shown, under the condition that other conditions remain unchanged, the extension section 130 is connected to the side of the support section 120, and the extension section 130 is inclined at a certain angle 150 to the horizontal 300 (the inclination angle in embodiment 1 is 0°). The extension piece of this embodiment can cope with a heat dissipation environment in which the air duct direction needs to be changed and is relatively special.

[0038] In summary, the radiator tooth plate extension structure of the utility model is suitable for various electronic devices, such as computers, servers, communication equipment, etc., and has broad application prospects; due to the simplification and optimization of the structure, the cleaning and maintenance of the radiator become easier, which helps to reduce the maintenance cost during long-term use; improving the heat dissipation efficiency helps to reduce the energy consumption of electronic equipment, thereby reducing the impact on the environment, which is in line with the development trend of green environmental protection; the radiator tooth plate extension structure of the utility model can improve the reliability and performance of electronic equipment, help to enhance the market competitiveness of products, and bring economic benefits to manufacturers.
