Description
Technical Field
[0001] The utility model belongs to the technical field of heat dissipation bases, and more specifically, relates to a heat dissipation base for a mechanical hard disk of an electronic computer. Background Art
[0002] With the development of information technology, computers have become an essential tool in people's daily lives. As one of the main devices for data storage, the mechanical hard disk (HDD, Hard Disk Drive) in a computer directly affects the overall performance of the computer in terms of its stability and reliability. Inside the mechanical hard disk, there are high-speed rotating disk platters and magnetic heads for performing read and write operations, which generate a large amount of heat during operation. If the heat is not dissipated in a timely and effective manner, high temperatures may cause the hard disk to malfunction, shorten its service life, or even result in data loss. Therefore, as an auxiliary heat dissipation device, heat dissipation bases are widely used in various types of computer systems. The main function of a heat dissipation base is to increase the heat exchange area between the hard disk and the external environment, accelerating the dissipation of heat, thereby maintaining the operating temperature of the hard disk within a safe range. Most traditional heat dissipation bases adopt a flat structure design and enhance the heat dissipation effect by adding heat dissipation fins or fans.
[0003] Although traditional heat dissipation bases can improve the heat dissipation of the hard disk to a certain extent, there are still some deficiencies in actual applications. These problems mainly include: since the heat generated by the hard disk is not evenly distributed, traditional flat heat dissipation bases often cannot provide effective heat dissipation support for areas with concentrated heat, resulting in local overheating. The existing heat dissipation bases often neglect the organization of airflows during design, making the cooling airflows unable to effectively cover the entire surface of the hard disk. Especially in the area below the hard disk, the airflows are easily blocked, significantly reducing the heat dissipation effect. Most heat dissipation bases adopt simple flat or straight plate structures, lacking innovative design concepts, unable to make full use of space to increase the heat dissipation area, and also unable to flexibly adjust the heat dissipation strategy according to the actual heat generation situation of the hard disk. To enhance the heat dissipation effect, many heat dissipation bases are equipped with active heat dissipation components such as fans. Although the heat dissipation speed can be increased, it also brings relatively large noise interference, affecting the user experience. Summary of the Utility Model
[0004] In view of this, the utility model provides a heat dissipation base for a mechanical hard disk of an electronic computer, which solves the drawback that traditional heat dissipation bases for mechanical hard disks of computers cannot provide effective heat dissipation support for areas with concentrated heat, and improves the heat dissipation uniformity.
[0005] The utility model is implemented as follows:
[0006] The utility model provides a heat dissipation base for a mechanical hard disk of an electronic computer, including a base body. Among them, one or more curved surface areas and a recessed area are provided on the base body. The curved surface area is integrally formed with the base body. The curvature of the curved surface area is designed to guide the cooling air flow along a predetermined path. The recessed area is located within the curved surface area and is used to place the hard disk. The shape of the recessed area matches the contour of the hard disk. At least one air inlet and an air outlet are provided on the base body, and the positions of the air inlet and the air outlet are arranged in cooperation with the design of the curved surface area.
[0007] The design of the curved surface area follows the basic principles of fluid mechanics. Its curvature and shape can guide the air flow to flow along the preset path, thereby forming a stable air flow field around the hard disk (HD) and improving the heat dissipation efficiency. Consider using a smooth and continuous curved surface design, such as using a sine function or a parabola function to define the shape of the curved surface, or it can also be other continuous and smooth curves, such as elliptical arcs, etc. The key is that this curved surface design can effectively guide the air flow to flow along the predetermined path, so as to achieve the effect of uniform heat dissipation.
[0008] On the basis of the above technical solution, a heat dissipation base for a mechanical hard disk of an electronic computer of the utility model can also be improved as follows:
[0009] Among them, the curved surface area uses a non-linear function to define its curvature, and the curvature radius of the curved surface area is between 5 mm and 50 mm.
[0010] Further, the number of the air inlets and the air outlets is at least two respectively, and they are respectively arranged on opposite sides of the base body to form a convection effect.
[0011] The beneficial effect of adopting the above improvement scheme is: This means that it may be an air inlet and an air outlet arranged on opposite sides, or two air inlets on one side and two air outlets on the other side, or other combination forms, as long as an effective convection can be formed.
[0012] Further, the surface of the curved surface area is subjected to matte treatment or coating treatment.
[0013] The material used for the coating treatment can be a material with a relatively high thermal conductivity, such as a silver powder coating, a graphene coating or other heat-conducting coatings. These coatings can not only improve the thermal conductivity performance of the surface, but also protect the base from corrosion and extend the service life.
[0014] Further, the curved surface area adopts a continuous curved surface design without corners or breakpoints.
[0015] Further, the concave area is located at the center or near the center of the curved surface area. The hard disk is placed within the concave area, and the curved surface area is formed around the concave area.
[0016] The curved surface area is formed around the concave area, and its curvature is designed such that air flow can be guided along the curve from the periphery of the concave area to the edge of the base body, thereby taking away the heat generated by the hard disk (HD).
[0017] Further, the curved surface area is designed with a sine wave shape, with its surface amplitude between 1 mm and 5 mm and its wavelength between 20 mm and 100 mm.
[0018] Further, the curved surface area is designed with a parabolic shape, with its opening width being 1 / 2 to 2 times the width of the hard disk and its depth being 1 / 10 to 1 / 5 of the opening width.
[0019] Further, the minimum curvature value and the maximum curvature value of the curved surface area are respectively between 0.01 / mm and 0.5 / mm.
[0020] Further, the base body is made of a heat-conducting material.
[0021] Compared with the prior art, the beneficial effects of an electronic computer mechanical hard disk heat dissipation base provided by the present utility model are as follows:
[0022] Improve heat dissipation uniformity: Through the carefully designed curved surface area, the present utility model can reasonably guide the cooling air flow to the area where the heat generated by the hard disk is most concentrated, effectively solving the problem of uneven heat dissipation of traditional heat dissipation bases.
[0023] Optimize air flow organization: The special shape of the curved surface area can promote the air flow to flow along a predetermined path, forming a stable air flow field and avoiding the low heat dissipation efficiency caused by air flow disorder.
[0024] Enhance heat dissipation efficiency: By using a curved surface area designed with a sine wave shape, a parabolic shape or other smooth curves, the effective heat dissipation area of the heat dissipation base is increased, further improving the overall heat dissipation performance.
[0025] Reduce noise: Since the present utility model relies on the curved surface structure to optimize the air flow path, it reduces the dependence on active heat dissipation components such as fans, thereby reducing the working noise and enhancing the user experience.
[0026] Simplify the installation process: The present utility model designs a structure that facilitates the installation and disassembly of the hard disk. Users can easily complete the fixation and disassembly of the hard disk, which is convenient for daily maintenance.
[0027] Prolong the service life: By using a high heat-conducting material and combining with surface treatment technology, the durability of the heat dissipation base is improved, and the service life of the product is prolonged. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Furthermore, in the above technical solution, the curved surface area 11 adopts a sine wave design, and its surface amplitude is between 1 mm and 5 mm, and the wavelength is between 20 mm and 100 mm. The amplitude can be set to 3 mm to 5 mm to ensure good contact between the hard disk and the curved surface, while avoiding being too high to cause structural instability;
[0044] The wavelength can be set to 50 mm to 100 mm to ensure that the air flow can flow smoothly along the waveform path;
[0045] The baseline offset can be set to 1 mm to 3 mm to ensure that the hard disk is placed in the sunken area and there is enough space for the air flow to pass through.
[0046] Furthermore, in the above technical solution, the minimum curvature value and the maximum curvature value of the curved surface area 11 are respectively between 0.01 / mm and 0.5 / mm.
[0047] Furthermore, in the above technical solution, the base body 10 is made of a heat-conducting material.

In this embodiment, it includes a base body 10. Among them, the base body 10 is provided with one or more curved surface areas 11 and a recessed area 12. The curved surface area 11 is integrally formed with the base body 10. The curvature of the curved surface area 11 is designed to guide the cooling air flow along a predetermined path. The recessed area 12 is located within the curved surface area 11 and is used to place the hard drive. The shape of the recessed area 12 matches the contour of the hard drive. The base body 10 is provided with at least one air inlet 20 and an air outlet 30, and the positions of the air inlet 20 and the air outlet 30 are arranged in cooperation with the design of the curved surface area 11.

[0050] Furthermore, in the above technical solution, the numbers of the air inlet 20 and the air outlet 30 are at least two respectively, and are respectively arranged on opposite sides of the base body 10 to form a convection effect.
[0051] Furthermore, in the above technical solution, the surface of the curved surface area 11 is subjected to a matte treatment or a coating treatment.

[0054] Furthermore, in the above technical solution, the curved surface area 11 adopts a parabolic design. Its opening width is 1 / 2 to 2 times the width of the hard drive, and the depth is 1 / 10 to 1 / 5 of the opening width. The opening width is 1 / 2 to 2 times the width of the hard drive to ensure that the hard drive is placed in the recessed area;
[0055] The depth is about 1 / 10 to 1 / 5 of the opening width to ensure that the air flow can pass through smoothly;
[0056] The selection of the constant should be determined according to the actual heat dissipation requirements and the results of aerodynamic simulation. Usually, the value is relatively small to obtain a gentle parabolic shape.
[0057] Furthermore, in the above technical solution, the minimum curvature value and the maximum curvature value of the curved surface area 11 are respectively between 0.01 / mm and 0.5 / mm.

According to the basic principles of fluid mechanics, a reasonable curved surface shape can effectively guide the air flow to flow along a predetermined path, forming a stable air flow field. This not only helps to improve the heat dissipation efficiency, but also reduces the air flow resistance and noise;
[0061] Curved surface design and optimization: The design of the curved surface area follows certain mathematical laws, such as sine wave shape, parabola shape, etc. By accurately calculating parameters such as curvature, amplitude, and wavelength, the air flow can smoothly flow through the hard disk heating area and quickly take away the heat. This design breaks the limitations of the single flat structure of the traditional heat dissipation base and realizes the effective management of the air flow;
[0062] Heat conduction theory: The heat dissipation base is made of high thermal conductivity materials and the thermal conduction performance is improved through surface treatment technology. The good contact between the curved surface area and the hard disk ensures that the heat can quickly transfer from the hard disk to the base and then be dissipated to the external environment through the base;
[0063] Aerodynamics: Through the research on the curved surface shape, the present utility model utilizes the aerodynamics principle to enable the air flow to form natural convection when passing through the heat dissipation base, achieving an efficient heat dissipation effect without the need for an external power source;
[0064] Structural mechanics analysis: During the design process, the requirements of structural mechanics are fully considered to ensure that the heat dissipation base remains stable under the weight of the hard disk and the vibration generated during operation, without deformation or damage;
[0065] Application of materials science: The present utility model selects materials with good thermal conductivity and fatigue strength, such as aluminum alloy or copper alloy, and at the same time, the surface is subjected to matte treatment or coating treatment to enhance the heat dissipation effect and protect the base from corrosion.
