Abstract
Description
Technical Field
[0001] This utility model relates to the field of switch technology, and more specifically, to a switch housing. Background Technology
[0002] Switches are indispensable in network use. A switch is a network device used for forwarding electrical (optical) signals. It is mainly used to provide a dedicated electrical signal path for any two network nodes connected to the switch.
[0003] In existing technologies, switch casings typically employ passive heat dissipation designs, such as ventilation holes and metal casings for heat conduction. These designs often involve overall airflow across the entire device or space, making it difficult to precisely target and effectively dissipate heat from localized high-temperature areas. This can affect the heat dissipation effect. Furthermore, during use, the switch ports are constantly exposed, making them prone to dust accumulation. When plugging network cables into the switch ports, dust may cause poor contact between the network cable and the pins inside the port, leading to malfunctions. Some devices use manually operated dust covers, which can prevent dust but also affect heat dissipation and require manual intervention. Utility Model Content

[0008] Assembly part, the assembly part is fixed to the rear end of the bottom shell;
[0009] The connecting part is installed on the bottom shell and the shell cover, wherein
[0010] The heat dissipation unit is driven to input cold air into the bottom shell, and the dust removal unit guides the cold air to several of the network ports.
[0011] The connecting part is used to lock the cover and the bottom shell when they are mated, and to restrict the heat dissipation part.
[0012] Furthermore, the dust removal unit includes a gas collecting sleeve fixed to the lower surface of the shell and with its opening facing the heat dissipation unit; an exhaust port opened at the lower end of the gas collecting sleeve; and several air supply channels disposed on the bottom shell and several network ports, and cooperating with the exhaust port to connect the gas collecting sleeve and several network ports.

[0015] Furthermore, the heat dissipation unit includes an assembly slot at the rear end of the bottom shell; a heat dissipation box inserted into the assembly slot; two cooling fans symmetrically mounted on the rear side of the heat dissipation box; two ventilation slots symmetrically opened on the heat dissipation box; a dustproof frame located on the rear side of the heat dissipation box and adapted to the two ventilation slots; two dust filters symmetrically fixed on the dustproof frame; heat dissipation fins mounted above the circuit board and fixed to the lower surface of the air collection sleeve; several heat dissipation holes symmetrically opened on the front ends of both sides of the bottom shell; and several interception nets respectively fixed on the front and rear sides of the two cooling fans.
[0016] The upper end of the heat sink abuts against the cover.
[0017] Furthermore, the heat dissipation unit also includes a rotating pin rotatably mounted on the dustproof frame, a positioning block fixed on the rotating pin, a through slot formed on the heat dissipation box and corresponding to the positioning block, an annular spring piece movably sleeved outside the rotating pin and disposed between the rotating pin and the dustproof frame.
[0018] Furthermore, the heat dissipation unit also includes two limiting protrusions symmetrically fixed on the positioning block; two limiting grooves symmetrically formed on the inner wall of the heat dissipation box; and two limiting blocks symmetrically fixed on the inner wall of the heat dissipation box.
[0019] Furthermore, the connecting part includes a connecting edge fixed to the lower end of the shell cover and adapted to the inner wall of the bottom shell; a plurality of locking blocks fixed to the front end of the connecting edge; and a plurality of locking slots formed at the front end of the bottom shell and adapted to the plurality of locking blocks.
[0020] Furthermore, the connecting part also includes two movable grooves symmetrically opened on the rear side of the upper surface of the shell cover; two Z-shaped fixing blocks movably installed in the two movable grooves respectively; two fixing grooves symmetrically opened on both sides of the bottom shell and adapted to the two Z-shaped fixing blocks respectively; and two return springs with one end fixedly connected to the inner wall of the two movable grooves respectively, and the other end fixedly connected to the two Z-shaped fixing blocks respectively.

Moreover, no manual intervention is required, ensuring user convenience. Attached Figure Description

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0036] like Figure 1-7 As shown, a switch housing includes: a bottom shell 1, a cover 2 disposed on the upper end of the bottom shell 1, a circuit board 3 installed inside the bottom shell 1, and a plurality of network ports 4 installed at the front end of the bottom shell 1 and connected to the circuit board 3.
[0037] Heat dissipation unit 5, which is installed on the bottom shell 1 and the shell cover 2;
[0038] Dust removal unit 6 is disposed on the bottom shell 1 and a plurality of network ports 4;
[0039] Assembly part 7, which is fixed to the rear end of the bottom shell 1;
[0040] Connecting part 8, the connecting part 8 is installed on the bottom shell 1 and the shell cover 2, wherein
[0041] The heat dissipation unit 5 is driven to input cold air into the bottom shell 1, and the dust removal unit 6 guides the cold air to several of the network ports 4.
[0042] The connecting part 8 is used to lock the cover 2 when it is docked with the bottom shell 1, and to restrict the heat dissipation part 5;
[0043] When in use, the heat dissipation part 5, the dust removal part 6, and the connecting part 8 work together. After the cold air enters the bottom shell 1 from the cooling fan 15, it flows in two directions, namely the heat dissipation path and the dust removal path.
[0044] Heat dissipation path: The heat flows through the heat dissipation fins 19 and the upper and lower sides of the circuit board 3, effectively exchanging heat to dissipate heat from the entire circuit board 3 and local high-heat areas. Hot air is discharged from the heat dissipation holes 39 to ensure the heat dissipation effect of the circuit board 3 and avoid heat accumulation.
[0045] Dust removal path: The dust is collected by the air collection sleeve 9, passes through the exhaust port 10, and is then directed to several network ports 4 through several air delivery channels 11. This continuously blows away the dust entering the network ports 4, preventing dust accumulation inside the network ports 4 from causing poor contact and malfunctions in subsequent network cables and pins inside the network ports 4. Compared to using a sealing cover to close the network ports 4, which requires opening and closing the dust cover every time the network cable is plugged in or unplugged, this method effectively reduces the frequency of manual intervention, ensures user convenience, and avoids the dust cover closing the network ports 4, which would affect the overall heat dissipation of the switch. Furthermore, heat dissipation and dust removal share the same air source, resulting in zero increase in power consumption and effective utilization of the dust removal airflow.
[0046] When the cover 2 is closed during switch assembly, the locking block 28 of the connecting part 8 and the Z-shaped fixing block 31 lock synchronously, forcing the heat dissipation box 14 to align with the air collection sleeve 9, and ensuring the connection between the air collection sleeve 9 and several air delivery channels 11, thus ensuring the effective flow of dust removal airflow.
[0047] The heat dissipation section 5 uses a quick-release dust filter 18, and the bottom shell 1 and the cover 2 can be quickly connected by the connecting part 8, which can prevent dust from entering the bottom shell 1 and contaminating the electrical components. The dust cover 17 can be quickly removed from the heat dissipation box 14 by rotating the rotating pin 21, so as to quickly replace and clean the dust filter 18 and ensure maintenance efficiency.
[0048] Optionally, the dust removal part 6 includes a gas collecting sleeve 9 fixed to the lower surface of the shell cover 2 and with its opening facing the heat dissipation part 5; an exhaust port 10 opened at the lower end of the gas collecting sleeve 9; and a plurality of air supply channels 11 disposed on the bottom shell 1 and a plurality of the network ports 4 and cooperating with the exhaust port 10 to connect the gas collecting sleeve 9 and the plurality of network ports 4.
[0049] A rubber ring 12 corresponding to the exhaust port 10 is fixedly connected to the lower surface of the gas collecting sleeve 9;
[0050] The air collecting sleeve 9 has a funnel-shaped interior. During use, the airflow generated by the heat dissipation part 5 is collected by the funnel-shaped structure of the air collecting sleeve 9 and accelerated by the decreasing cross-sectional area. Then, after entering several air supply channels 11 through the exhaust port 10, it forms a linear airflow beam that directly impacts the dust-prone areas inside several network ports 4 for cleaning. This prevents dust from entering the network ports 4 and causing poor contact during wiring. The rubber ring 12 is compressed and deformed when the cover 2 is closed to form an airtight interface, preventing airflow leakage and ensuring dust removal efficiency.
[0051] Optionally, the heat dissipation unit 5 includes an assembly slot 13 formed at the rear end of the bottom shell 1; a heat dissipation box 14 inserted into the assembly slot 13; two cooling fans 15 symmetrically mounted on the rear side of the heat dissipation box 14; two ventilation slots 16 symmetrically formed on the heat dissipation box 14; a dustproof frame 17 located on the rear side of the heat dissipation box 14 and adapted to the two ventilation slots 16; two dust filters 18 symmetrically fixed on the dustproof frame 17; heat dissipation fins 19 mounted above the circuit board 3 and fixed to the lower surface of the air collection sleeve 9; a plurality of heat dissipation holes 39 symmetrically formed at the front ends of both sides of the bottom shell 1; and a plurality of interception nets 38 respectively fixed on the front and rear sides of the two cooling fans 15.
[0052] The upper end of the heat sink 14 abuts against the cover 2;
[0053] In use, the two cooling fans 15 draw in cool air through the ventilation slots 16. Part of the air cools the upper side of the circuit board 3 through the gap between the cooling fins 19 and the circuit board 3, while the other part cools the lower side of the circuit board 3. Hot air is then exhausted through the ventilation holes 39 on both sides of the bottom shell 1, ensuring both intake and exhaust air pressure. The cooling fins 19 directly contact the high-heat areas of the circuit board 3, ensuring effective heat conduction and dissipation. Simultaneously, the cooling fins 19 are directly connected to the air collection sleeve 9, allowing the dust removal section 6 to also assist in heat dissipation. When the airflow enters the bottom shell 1 through the heat sink 14, the dust cover 17 and the dust filter 18 form an air intake filtration system, which effectively intercepts dust particles, allowing the dust to be stored in the heat sink 14 to prevent contamination of electrical components such as the circuit board 3 inside the bottom shell 1. It also prevents the dust from being thrown back into the air when it leaves the dust filter 18, thus affecting the surrounding environment. Furthermore, the intercepting nets 38 set on the front and rear sides of the cooling fan 15 can prevent objects from contacting and damaging the cooling fan 15. In addition, moisture-absorbing materials can be used in the heat sink 14 to absorb moisture in the cooling airflow, preventing the internal electrical components from being damaged by moisture.
[0054] Optionally, the heat dissipation unit 5 further includes a rotating pin 21 rotatably mounted on the dustproof frame 17, a positioning block 20 fixed on the rotating pin 21, a through slot 22 corresponding to the positioning block 20 and opened on the heat dissipation box 14, an annular spring piece 23 movably sleeved on the outside of the rotating pin 21 and disposed between the rotating pin 21 and the dustproof frame 17; in use, pressing and rotating the rotating pin 21 makes the positioning block 20 coincide with the through slot 22, so as to quickly remove the dustproof frame 17 from the heat dissipation box 14 for cleaning, which is convenient to use and ensures the cleaning efficiency of the heat dissipation box 14; and the annular spring piece 23 can provide continuous clamping force when the dustproof frame 17 is installed on the heat dissipation box 14 and the positioning block 20 and the through slot 22 are misaligned, so as to ensure that the positioning block 20 is tightly attached to the inner wall of the heat dissipation box 14 and achieves a self-locking effect.
[0055] Optionally, the heat dissipation part 5 further includes two limiting protrusions 24 symmetrically fixed on the positioning block 20; two limiting grooves 25 symmetrically formed on the inner wall of the heat dissipation box 14; and two limiting blocks 26 symmetrically fixed on the inner wall of the heat dissipation box 14. The two limiting blocks 26 can limit the rotation direction and rotation angle of the rotating pin 21, ensuring that after the rotating pin 21 rotates, the two limiting protrusions 24 can be smoothly inserted into the two limiting grooves 25, ensuring the assembly stability of the dustproof frame 17 on the heat dissipation box 14, and preventing it from being dislodged due to impact.
[0056] Optionally, the connecting part 8 includes a connecting edge 27 fixed to the lower end of the cover 2 and adapted to the inner wall of the bottom shell 1; a plurality of locking blocks 28 fixed to the front end of the connecting edge 27; and a plurality of slots 29 formed at the front end of the bottom shell 1 and adapted to the plurality of locking blocks 28.
[0057] Optionally, the connecting part 8 further includes two movable grooves 30 symmetrically opened on the rear side of the upper surface of the cover 2; two Z-shaped fixing blocks 31 respectively movably installed in the two movable grooves 30; two fixing grooves 32 symmetrically opened on both sides of the bottom shell 1 and respectively adapted to the two Z-shaped fixing blocks 31; and two return springs 33, one end of which is fixedly connected to the inner wall of the two movable grooves 30 respectively, and the other end of which is fixedly connected to the two Z-shaped fixing blocks 31 respectively. In use, the cover 2 is first aligned with the bottom shell 1, and several locking blocks 28 are controlled to be inserted into several locking slots 29 respectively. At this time, under the elastic push of the two return springs 33, the two Z-shaped fixing blocks 31 can be locked into the two slots respectively. Within the fixing groove 32, a double locking mechanism is established between the bottom shell 1 and the cover 2, ensuring a secure connection. The barbed structure and guide slope of the locking block 28 facilitate its assembly within the slot 29 and ensure stability after insertion. When maintenance of the switch body is required, simply press the two Z-shaped fixing blocks 31 simultaneously to move them in the two movable slots 30, overcoming the spring force of the reset spring 33. This allows the two Z-shaped fixing blocks 31 to disengage from the two fixing slots 32, and then the cover can be lifted, allowing the locking block 28 to slide out along the inclined guide surface of the slot 29. The entire process requires no tools, ensuring quick disassembly and assembly of the cover 2, facilitating switch maintenance, and enabling the removal and cleaning of the heat sink 14.
[0058] Optionally, the assembly part 7 includes an L-shaped bracket 34 fixed to the rear end of the bottom shell 1 and secured to the rear surface of the bottom shell 1 by a plurality of bolts; a plurality of rear pads 35 fixed between the bottom shell 1 and the L-shaped bracket 34; a lower pad 36 fixed to the L-shaped bracket 34 and abutting against the lower surface of the bottom shell 1; and a plurality of assembly holes 37 symmetrically opened on the L-shaped bracket 34. The plurality of assembly holes 37 on the L-shaped bracket 34 facilitate horizontal placement and wall mounting of the L-shaped bracket 34, supporting multiple installation methods. The lower pads 36, together with the plurality of rear pads 35, ensure that the bottom shell 1 can always remain suspended, maintaining the distance between the bottom shell 1 and the L-shaped bracket 34, facilitating the passage of airflow around the bottom shell 1, and not affecting the heat dissipation of the bottom shell 1.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
