Description

Technical Field

[0001] The utility model relates to the field of switches, and in particular to a heat dissipation chassis for switches. Background Art

[0002] A switch means "switch" and is a network device used for forwarding electrical (optical) signals. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. The most common switch is the Ethernet switch, and other common ones include telephone voice switches, fiber optic switches, etc.

[0003] A heat dissipation fan is installed inside the switch to dissipate heat from the components inside the switch. The heat dissipation fan is installed inside the switch to extract the hot air inside the switch and discharge it out of the switch through the vents.

[0004] Existing switches dissipate heat through vents on both sides. Dust in the air will also enter through the vents and accumulate on the internal components of the switch, making it inconvenient for staff to clean. At the same time, the cooling fan of the switch is too close to the electronic components. While the electronic components are dissipating heat, the cooling fan motor is also heating up, which can easily lead to heat source superposition and reduce the heat dissipation effect.

[0010] Grooves are respectively provided on both sides of the switch box, and the switch box includes a plurality of heat dissipation ports provided inside the grooves. A filter plate is provided on one side of the heat dissipation port, and the filter plate is fixedly connected to the external groove of the switch box by bolts.

[0012] By adopting the above technical solution, the staff loosens the bolts on the rear cover and pulls the rear cover through the lifting plate on one side of the rear cover. The rear cover drives the limit frame and the heat dissipation assembly to slide on the slider.

[0014] By adopting the above technical solution, the retaining plate fixes the position of the heat dissipation assembly to prevent the heat dissipation assembly from shaking due to external force, thereby loosening the bolts of the internal structure of the heat dissipation assembly, making it easier for the rear cover to drive the heat dissipation assembly to move outward at the same time.

[0015] As a preferred solution of a heat dissipation chassis for a switch described in the utility model, one side of the retaining plate is fixedly connected to the side of the rear cover plate by bolts, the side of the retaining plate close to the rear cover plate is fixedly connected to the side of the heat dissipation assembly by bolts, and the square groove plate, the limit frame and the retaining plate are all located on the same side of the rear cover plate.

At the same time, the front card separates the cooling fan motor from the electronic components inside the switch box to avoid the heat of the cooling fan motor and the heat of the electronic components inside the switch box from overlapping, which affects the heat dissipation of the electronic components inside the switch box.

[0020] By adopting the above technical solution, the base has a certain bearing capacity. When the rear cover is moved out from the opening of the switch box, the sliding groove of the limit frame engages the slider of the switch box, and the bottom of the rear cover stands upright on the bottom of the base, which reduces the bearing capacity of the slider and facilitates the staff to replace the arc filter plate.

[0021] (III) Beneficial effects

[0022] The utility model provides a heat dissipation chassis for a switch, which has the following beneficial effects:

[0023] 1. The staff starts the cooling fan through the switch of the switch box. The cooling fan operates to extract the air outside the switch box and blow out the air inside the switch box. At the same time, the air outside the switch box enters the switch box through the vents, arc filter plate and ventilation plate of the rear cover plate to cool the electronic components inside the switch box. The arc filter plate filters the incoming air to prevent dust inside the air from entering and accumulating inside the switch box. The air with heat is blown out of the switch box through the cooling fan, and the hot air is discharged from the switch box through the heat dissipation port and the filter plate. When the cooling fan stops running, the air inside and outside the switch box will circulate through the heat dissipation port and the vents, and the arc filter plate and the filter plate can filter the incoming air. The filter plate is fixed to the outside of the switch box by bolts, which is convenient for the staff to replace and clean. The arc filter plate is movably connected in the snap-in groove between the ventilation plate and the square groove plate of the heat dissipation component. The staff can replace and clean the filter plate by stretching the arc filter plate. This setting is convenient for the heat dissipation of the electronic components inside the switch box, while keeping the internal structure of the switch box clean and tidy, which is convenient for the staff to clean and maintain.

[0024] 2. If the heat dissipation assembly needs to be repaired, the staff loosens the bolts on the rear cover and pulls the rear cover through the lifting plate on one side of the rear cover. The rear cover drives the limit frame and the heat dissipation assembly to slide on the slider. Sliding grooves are provided on both sides of the limit frame, and the sliding grooves are engaged with the sliders on both sides of the inner wall of the switch box. The heat dissipation assembly is placed inside the limit frame so that the heat dissipation assembly is close to the rear cover to dissipate the electronic components inside the switch box. At the same time, the staff loosens the bolts on the retaining plates on both sides of the heat dissipation assembly to facilitate the disassembly and maintenance of the heat dissipation assembly. When the cooling fan stops running, the motor of the cooling fan is in a heating state. The cooling assembly is located on one side of the rear cover and fits with the vent of the rear cover, which is convenient for the heat dissipation and ventilation of the cooling fan motor. At the same time, the front card separates the cooling fan motor from the electronic components inside the switch box to avoid the heat of the cooling fan motor overlapping with the heat of the electronic components inside the switch box, affecting the heat dissipation of the electronic components inside the switch box.

[0036] An opening is provided on one side of the heat dissipation component 1. The heat dissipation component 1 includes a front card plate 101 fixedly connected to the opening. The front card plate 101 is fixedly connected to the outer side of the heat dissipation fan 102. A ventilation plate 103 is provided on one side of the heat dissipation fan 102.

The staff can replace and clean the filter plate by stretching the arc filter plate 2. This arrangement is convenient for the heat dissipation of the electronic components inside the switch box 5, while keeping the internal structure of the switch box 5 clean and tidy, which is convenient for the staff to clean and repair.

[0041] Specifically, the side of the square groove plate 104 away from the arc filter plate 2 is movably connected to the side of the rear cover plate 3, and the heat dissipation component 1 is movably connected to the inside of the limiting frame 301. The sliding grooves 302 are provided on both sides of the limiting frame 301.

[0043] Specifically, one side of the fixing plate 303 is fixedly connected to the side of the rear cover plate 3 by bolts, and the side of the fixing plate 303 close to the rear cover plate 3 is fixedly connected to the side of the heat dissipation assembly 1 by bolts, and the square groove plate 104, the limiting frame 301 and the fixing plate 303 are all located on the same side of the rear cover plate 3.

[0044] Specifically, a plurality of vents 304 are provided on the rear cover 3 , and the vents 304 are used for air to enter the interior of the heat dissipation assembly 1 . The side of the rear cover 3 away from the heat dissipation assembly 1 is movably connected to the lifting plate 4 , and the lifting plate 4 is located on the top of the vents 304 .

[0045] Furthermore, if the heat dissipation component 1 needs to be repaired, the staff loosens the bolts on the rear cover 3, and pulls the rear cover 3 through the lifting plate 4 on one side of the rear cover 3, and the rear cover 3 drives the limit frame 301 and the heat dissipation component 1 to slide on the slider 501. Sliding grooves 302 are provided on both sides of the limit frame 301, and the sliding grooves 302 are engaged with the sliders 501 on both sides of the inner wall of the switch box 5. The heat dissipation component 3 is placed inside the limit frame 301, so that the heat dissipation component 1 is close to the rear cover 3 to dissipate the electronic components inside the switch box 5. At the same time, the staff loosens the bolts on the rear cover 3, and the rear cover 3 drives the limit frame 301 and the heat dissipation component 1 to slide on the slider 501. The bolts on the fixing plates 303 on both sides of the heat dissipation component 1 facilitate the disassembly and maintenance of the heat dissipation component 1. When the heat dissipation fan 102 stops running, the motor of the heat dissipation fan 102 is in a heating state. The heat dissipation component 1 is located on one side of the rear cover 3 and fits with the vent 304 of the rear cover 3, which is convenient for the heat dissipation and ventilation of the motor of the heat dissipation fan 102. At the same time, the front card plate 101 separates the motor of the heat dissipation fan 102 from the electronic components inside the switch box 5 to avoid the heat of the heat dissipation fan 102 motor and the heat of the electronic components inside the switch box 5 overlapping, which affects the heat dissipation of the electronic components inside the switch box 5.

[0046] Working principle: when the staff replaces and cleans the filter device of the switch box 5 and the heat dissipation component 1, they first remove the bolts on both sides of the outside of the switch box 5 to separate the filter plate 6 from the heat dissipation port 502, which is convenient for the staff to replace and clean the filter plate 6. The staff then loosens the bolts on one side of the rear cover plate 3 and pulls the rear cover plate 3 through the lifting plate 4 on the rear cover plate 3. The rear cover plate 3 slides on the base 7, and the limit frame 301 slides with the heat dissipation component 1 on the sliders 501 on both sides of the inner wall of the switch box 5. When the heat dissipation component 1 is moved out of the switch box 5, the staff lifts the arc filter plate 2 on the top of the heat dissipation component 1, and the arc filter plate 2 can be pulled out for replacement and cleaning. The arc filter plate 2 is located in the engaging groove 105 between the ventilation plate 103 and the square groove plate 104 of the heat dissipation component 1, which is convenient for the staff to replace and install the filter device. The staff starts the cooling fan 102 through the switch of the switch box 5. The cooling fan 102 operates to extract air outside the switch box 5, so that the inside of the switch box 5 The hot air is blown out of the chassis, and at the same time, the air outside the switch box 5 enters the switch box through the vents 304 of the rear cover 3, the arc filter plate 2 and the ventilation plate 103, and the electronic components inside the switch box 5 are cooled. The arc filter plate 2 filters the incoming air to prevent dust inside the air from entering and accumulating inside the switch box. The air with heat is blown out of the switch box 5 through the heat dissipation fan 102, and the hot air passes through the heat dissipation port 502 and the filter plate 6 to be discharged from the switch box 5. When the heat dissipation fan 102 stops running, the air inside and outside the switch box 5 will circulate through the heat dissipation port 502 and the vents 304, and the arc filter plate 2 and the filter plate 6 can effectively filter the dust from the incoming air. This arrangement is convenient for the heat dissipation of the electronic components inside the switch box 5, keeps the internal structure of the switch box 5 clean and tidy, and is convenient for the staff to clean and repair. At the same time, it avoids the heat of the heat dissipation fan 102 motor and the heat of the electronic components inside the switch box 5 overlapping, affecting the heat dissipation of the electronic components inside the switch box 5.
