Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy shells, and more particularly to an aluminum alloy shell structure with heat dissipation and moisture protection. Background Technology

[0002] An aluminum alloy housing is a shell structure made primarily of aluminum alloy, used to house and protect the internal components of equipment. It is mainly composed of an alloy of aluminum and other metallic elements in a specific ratio. Different alloy formulations result in different performance characteristics. Through appropriate casting, forging, or stamping processes, an aluminum alloy housing can form a complete and robust shell structure that effectively resists external impacts, compression, and other mechanical damage, providing a stable protective space for the internal equipment components.

[0003] A search revealed that Chinese Patent Publication No. CN220368894U discloses an aluminum alloy shell structure with heat dissipation and dust prevention. By setting a dustproof heat dissipation mesh fixing mechanism, the aluminum alloy shell can dissipate heat and cool down through the mesh of the dustproof heat dissipation mesh. At the same time, dust is not easy to enter the interior of the aluminum alloy shell, and it is also convenient to open the dustproof heat dissipation mesh for regular maintenance of the aluminum alloy shell.

[0004] In the above technical solution, the heat dissipation effect is improved by fixing the dustproof heat dissipation mesh, while preventing dust from entering. However, liquid water can easily enter the aluminum alloy shell through the mesh holes of the heat dissipation mesh. The accumulation of liquid water will lead to an increase in humidity inside the aluminum alloy shell, which will affect the internal equipment. Therefore, an aluminum alloy shell structure with heat dissipation and moisture protection is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides an aluminum alloy shell structure with heat dissipation and moisture protection, which aims to improve the problem in the prior art where liquid water can easily enter the shell through the heat dissipation mesh, leading to increased internal humidity and affecting the equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an aluminum alloy shell structure with heat dissipation and moisture protection, comprising a shell body, a shell cover provided on the outer side of the shell body, a cooling fan fixedly connected to the inner wall of the top of the shell body, a V-shaped heat dissipation hole opened on the side wall of the shell body, an inclined block fixedly connected to the inner wall of the V-shaped heat dissipation hole, a rounded corner opened on the surface of the inclined block, a heat sink fixedly connected to the inner wall of the shell cover, a U-shaped sealing ring fixedly connected to the outer wall of the heat sink, and a moisture absorption component provided on the surface of the shell cover.

[0007] As a further description of the above technical solution: The end of the inclined block near the inner wall of the outer shell is higher than the end of the inclined block near the outer wall of the outer shell.

[0008] As a further description of the above technical solution: The heat sink penetrates the housing cover, and the outer surface of the U-shaped sealing ring is fixedly connected to the inner wall of the housing cover.

[0009] As a further description of the above technical solution: The moisture-absorbing component includes a mounting groove, a magnetic ring is fixedly connected to the inner wall of the mounting groove, a magnetic block is magnetically connected to the inner wall of the magnetic ring, a mounting plate is fixedly connected to the outer wall of the magnetic block, and a moisture-absorbing layer is fixedly connected to the side wall of the mounting plate.

[0010] As a further description of the above technical solution: The mounting groove is located on the outer wall of the cover near the outer shell body.

[0011] As a further description of the above technical solution: The mounting plate is fitted onto the outer wall of the heat sink.

[0012] As a further description of the above technical solution: The outer wall of the heat sink is fixedly connected with reinforcing ribs, and the outer wall of the shell is fixedly connected with a support frame. The outer wall of the support frame is provided with a vent hole.

[0013] As a further description of the above technical solution: The vent holes are arranged at an angle.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by combining structures such as a cooling fan, V-shaped heat dissipation holes, inclined plate, rounded corners, heat sink, U-shaped sealing ring and moisture absorption component, the aluminum alloy shell can provide a relatively heat dissipation and moisture-proof space for the equipment, increase the heat exchange efficiency with the outside air, and has high heat dissipation efficiency and good liquid water and moisture-proof effect.

[0015] 2. In this utility model, by providing structures such as reinforcing ribs, support frames, and vent holes, the rigidity and strength of the heat sink can be guaranteed, preventing damage. Furthermore, when the cover is separated from the outer shell, the support frame can prevent the heat sink from contacting the placement surface when the cover is placed, further protecting the heat sink and thus ensuring stable heat exchange function.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3This utility model provides an embodiment of an aluminum alloy shell structure with heat dissipation and moisture resistance, comprising a shell body 1, a shell cover 2 on the outer side of the shell body 1, the shell cover 2 being fixed to the shell body 1 by four sets of bolts arranged in a rectangular array, a cooling fan 3 being fixedly connected to the inner wall of the top of the shell body 1, the air inlet of the cooling fan 3 being located outside the shell body 1 and equipped with a filter screen, V-shaped heat dissipation holes 4 being provided on the side walls of the shell body 1, a plurality of V-shaped heat dissipation holes 4 being provided and distributed at equal intervals on both sides of the outer wall of the shell body 1, achieving the effect of heat dissipation and ventilation, and an inclined block 5 being fixedly connected to the inner wall of the V-shaped heat dissipation hole 4, the end of the inclined block 5 near the inner wall of the shell body 1 being higher than the end of the inclined block 5 near the outer wall of the shell body 1. The design makes it difficult for dust and impurities to overcome their own weight and enter the interior of the outer shell 1. The surface of the inclined block 5 is provided with rounded corners 6. The rounded corners 6 allow the dust or liquid on the surface of the V-shaped heat dissipation holes 4 to naturally converge and transfer to the inclined block 5 by gravity. The inner wall of the shell cover 2 is fixedly connected with heat sinks 7. The heat sinks 7 penetrate the shell cover 2. Several groups of heat sinks 7 are provided and distributed at equal distances on the shell cover 2. Most of the heat sinks 7 are located on the outside of the shell cover 2, and a small part of the heat sinks 7 are inside the outer shell 1 after the shell cover 2 is placed on the outer shell 1. The outer wall of the heat sink 7 is fixedly connected with a U-shaped sealing ring 8. The outer surface of the U-shaped sealing ring 8 is fixedly connected to the inner wall of the shell cover 2. The U-shaped sealing ring 8 can ensure the tightness of the installation between the shell cover 2 and the heat sink 7 and the shell cover 2.

[0020] Reference Figures 3-5 The surface of the cover 2 is provided with a moisture-absorbing component, which includes a mounting groove 9, a magnetic ring 10, a magnetic block 11, a mounting plate 12, and a moisture-absorbing layer 13. Two sets of each of the mounting groove 9, magnetic ring 10, and magnetic block 11 are provided, symmetrically arranged about the central axis of the cover 2. The mounting groove 9 is located on the outer wall of the cover 2 near the outer shell body 1. The inner wall of the mounting groove 9 is fixedly connected to the magnetic ring 10, and the inner wall of the magnetic ring 10 is magnetically connected to the magnetic block 11. The outer wall of the magnetic block 11 is fixedly connected to the mounting plate 12, which is fitted onto the moisture-absorbing layer 13. On the outer wall of the heat sink 7, the mounting plate 12 is arranged in a similar U-shape, which can be fitted onto multiple heat sinks 7 to avoid contact between them. The side wall of the mounting plate 12 is fixedly connected to a moisture-absorbing layer 13. The substrate of the moisture-absorbing layer 13 is made of modified epoxy resin-based thermal conductive adhesive or silicone-based thermal conductive adhesive, pre-coated with pressure-sensitive adhesive and with release paper to achieve quick installation and direct bonding to the mounting plate 12. A support skeleton is set in the substrate and filled with moisture-absorbing material, such as molecular sieve and silica gel mixed particles, to meet the moisture absorption and moisture-proof function while ensuring stability and preventing it from falling off.

[0021] Reference Figure 1 , Figures 3-4The outer wall of the heat sink 7 is fixedly connected with reinforcing ribs 14. Several sets of reinforcing ribs 14 are set on the surface of the heat sink 7 on the outside of the shell cover 2. While not changing the shape and thickness of the heat sink 7, the rigidity and strength of the heat sink 7 are increased. The outer wall of the shell cover 2 is fixedly connected with a support frame 15. When the shell cover 2 is separated from the outer shell body 1 and needs to be placed, the support frame 15 can contact the table or the ground to avoid friction between the reinforcing ribs 14 or the heat sink 7 and the contact surface. The outer wall of the support frame 15 is provided with a vent hole 16. The vent hole 16 is set at an angle. The vent hole 16 can reduce the risk that the heat sink 7 will have less contact with air due to the support frame 15 blocking the heat sink 7.

[0022] Working principle: The moisture-absorbing layer 13 is adhered to the mounting plate 12, and the mounting plate 12 is fitted onto the heat sink 7 that forms an integral part, until the magnetic block 11 is embedded in the mounting groove 9 and magnetically attracted to the magnetic ring 10. After the mounting plate 12 is installed, it is tightly attached to the cover 2. At this time, the equipment is placed inside the outer shell 1. After the cover 2 is placed on the outer shell 1, the two are fixed together with bolts. The cooling fan 3 is turned on to blow air into the inner shell 1 for daily heat dissipation. The V-shaped heat dissipation holes 4 serve the function of heat dissipation and ventilation. The heat source can flow out through the V-shaped heat dissipation holes 4. The heat sink 7 located inside the outer shell 1 can contact the equipment and transfer the heat source generated by it to itself. Since most of the heat sink 7 is on the outside of the outer shell 1 and in contact with the air, it exchanges heat with the inner shell 1. Combined with the moisture-proof and moisture-absorbing force of the moisture-absorbing layer 13, the outer shell 1 and the cover 2 can provide a relatively stable environment to protect the internal equipment when it is placed.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
