Description

Technical Field

[0001] This utility model relates to a dustproof heat dissipation box for electrical equipment. Background Technology

[0002] Electrical equipment boxes generally refer to enclosed containers or enclosures used to house, protect, and organize electrical components. They can be further classified into several categories depending on different application scenarios, functional requirements, protection levels, and installation methods. The most widely used type is the distribution box, which mainly serves to protect circuit breakers, electricity meters, switches, and other instruments in power distribution equipment from dust and provide safety protection.

[0003] However, in actual use, existing electrical equipment boxes, due to their enclosure design, can enclose and protect power distribution facilities from dust, ensuring safety and dust protection. However, due to the heat accumulation problem in power distribution facilities during operation, existing electrical equipment boxes usually use built-in fans for passive air cooling. Due to the thermal conductivity of air and the limited area for heat exchange, existing electrical equipment boxes usually have poor heat dissipation efficiency. Another implementation method is to install fans at the top and bottom of the box, with air blowing from the bottom and the top fan carrying away heat, which generates dust and can lead to short circuits in the power distribution equipment.

[0034] The enclosure 1 is rectangular in shape and has opposite upper and lower sides, opposite front and rear sides, and opposite left and right sides. A door 19 is rotatably mounted on one side of the enclosure 1. Opening the door 19 allows the placement of a power distribution unit 18 inside the enclosure 1, while closing the door 19 seals the enclosure 1. The power distribution unit 18 can be a meter, capacitor, etc. Ventilation openings, such as on the left and / or right sides of the enclosure 1, are provided on the enclosure 1 to communicate with the atmosphere.

[0035] The bottom of the enclosure 1 is provided with a fixing seat 20 to support the enclosure 1 and facilitate the overall fixing and installation of the distribution box. In one embodiment, the fixing seat 20 includes a left plate, a right plate and a middle support plate connecting the left plate and the right plate. The left plate and the right plate are horizontally arranged and the middle support plate is U-shaped.

[0036] The heat-conducting partition 2 is vertically installed inside the housing 1, which can divide the space inside the housing 1 into a front receiving space and a rear receiving space (or a left receiving space and a right receiving space). Taking the front and rear as an example, the first heat-conducting component and the second heat-conducting component are respectively installed on the front and rear sides of the heat-conducting partition 2. The first heat-conducting component includes a heat-conducting frame 3, a heat-conducting pipe 4, and a heat-conducting connecting plate 5. The power distribution unit 18 is installed on the side of the heat-conducting frame 3 away from the heat-conducting partition 2. The heat-conducting pipe 4 and the power distribution unit 18 are respectively located on the front and rear sides of the heat-conducting frame 3. The heat-conducting pipe 4 is connected between the heat-conducting partition 2 and the heat-conducting frame 3. The heat-conducting connecting plate 5 is connected to the heat-conducting frame 3. The heat-conducting pipe 4 and the power distribution unit 18 are both connected to the heat-conducting connecting plate 5.

[0037] In this example, see Figure 5 The heat-conducting frame 3 includes a first longitudinal member 31, a second longitudinal member 32, and a transverse support member. The first longitudinal member 31 and the second longitudinal member 32 are arranged opposite each other and both extend vertically. The transverse support member extends horizontally and is connected to both the first longitudinal member 31 and the second longitudinal member 32. The power distribution unit 18 is connected to the side of the transverse support member away from the heat-conducting partition 2. The heat-conducting connecting plate 5 is connected to the transverse support member. The transverse support member includes two transverse plates 33, which are distributed vertically along the housing 1 and maintain a gap between them. The heat-conducting connecting plate 5 is connected between the two transverse plates 33.

[0038] In some embodiments, the heat pipe 4 has an annular structure, such as a square annular structure, and the heat pipe 4 is connected between the heat-conducting partition 2 and the heat-conducting frame 3; or the heat pipe 4 includes a first pipe body 41 and a second pipe body 42, and the heat dissipation box also includes a heat-conducting plate 6, which is connected to the side of the heat-conducting partition 2 facing the heat-conducting frame 3, such as by a bolt and nut assembly; the first pipe body 41 is located above the second pipe body 42, and the two opposite ends of the first pipe body 41 are respectively connected to the upper part of the heat-conducting plate 6 and the upper part of the heat-conducting connecting plate 5, and the two opposite ends of the second pipe body 42 are respectively connected to the lower part of the heat-conducting plate 6 and the lower part of the heat-conducting connecting plate 5.

[0039] In some embodiments, the heat-conducting connecting plate 5 is U-shaped. While connecting the heat-conducting frame 3 and the heat-conducting pipe 4, the power distribution unit 18 is connected in the U-shaped space of the heat-conducting connecting plate 5, which can better fix the power distribution unit 18.

[0040] In some embodiments, multiple power distribution units 18, multiple heat conduction pipes 4, and multiple heat conduction connecting plates 5 are provided, with each power distribution unit 18 corresponding to a heat conduction pipe 4 and a heat conduction connecting plate 5. Multiple power distribution units 18 can be installed on a transverse support member, and the multiple power distribution units 18 extend along the length direction of the transverse support member.

[0041] In this example, the transverse support is detachably connected to the first longitudinal member 31 and the second longitudinal member 32. The implementation method is as follows: the first longitudinal member 31, the second longitudinal member 32 and the transverse support are provided with corresponding mounting holes. The first longitudinal member 31 has multiple mounting holes and the second longitudinal member 32 has multiple mounting holes. The position of the transverse support can be determined by selecting the mounting holes on the first longitudinal member 31 and the second longitudinal member 32, which provides high flexibility.

[0042] In this example, the second heat-conducting component includes a cooling fan 7 and a heat sink 8. The cooling fan 7 is located at the ventilation opening of the housing 1, and the heat sink 8 is located on the side of the heat-conducting partition 2 away from the first heat-conducting component. The heat sink 8 extends in the left-right direction and is arranged adjacent to the cooling fan 7, with a gap between them. A fixing frame 16 is provided inside the housing 1, extending along the height direction of the housing 1. The cooling fan 7 is mounted on the fixing frame 16, which is used to fix and support the cooling fan 7. Fixing frames 16 are provided on both the left and right sides of the housing 1. Multiple cooling fans 7 are mounted on one fixing frame 16, and the multiple cooling fans 7 are arranged sequentially up and down along the height direction of the fixing frame 16.

[0043] Ventilation openings are provided on both the left and right sides of the enclosure 1. Cooling fans 7 are installed on both the left and right sides inside the enclosure 1. The cooling fan 7 on one side blows room temperature air into the enclosure 1, while the cooling fan 7 on the other side blows the air after heat exchange out of the enclosure 1 through the ventilation openings, ensuring airflow.

[0044] In some embodiments, a downwardly recessed heat-conducting groove 81 is provided on the upper side of the heat sink 8, and / or an upwardly recessed heat-conducting groove 81 is provided on the lower side of the heat sink 8, with the heat-conducting groove 81 extending in the left-right direction. Providing the heat-conducting groove 81 increases the contact area between the heat sink 8 and the air, greatly increasing the heat dissipation area and effectively improving the heat dissipation efficiency of the distribution box. Furthermore, the heat-conducting groove 81 can also guide the airflow.

[0045] In some embodiments, multiple heat sinks 8 are provided, and the multiple heat sinks 8 are arranged vertically along the height direction of the housing 1, with a gap maintained between adjacent heat sinks 8.

[0046] In some embodiments, the dustproof and heat dissipation box for electrical equipment also includes a maintenance plate 15. At least one opening is located on the left or right side of the box body 1. The maintenance plate 15 is positioned at the opening, and its lower side is rotatably connected to the box body 1 via a hinge. When the device is under maintenance, rotating the maintenance plate 15 opens the opening; when the device is in operation, the maintenance plate 15 closes the opening. The maintenance plate 15 is vertically mounted and has a ventilation opening 151 that communicates with both the box body 1 and the atmosphere.

[0047] The inspection plate 15 is opposite to the cooling fan 7. The cooling fan 7 blows room temperature air into the housing 1 and out of the housing 1 through the vent 151 on the inspection plate 15. In a preferred embodiment, there are two inspection plates 15, which are respectively arranged on the left and right sides of the housing 1. Cooling fans 7 are arranged on both the left and right sides of the housing 1. The inspection plate 15 on the left side of the housing 1 is opposite to the cooling fan 7 on the left side of the housing 1, and the inspection plate 15 on the right side of the housing 1 is opposite to the cooling fan 7 on the right side of the housing 1. The cooling fan 7 on the left side blows room temperature air into the housing 1 through the vent 151 on the inspection plate 15, and the cooling fan 7 on the right side blows the air after heat exchange along the vent 151 on the inspection plate 15 to the outside of the housing 1.

[0048] In some embodiments, the inspection plate 15 has multiple ventilation openings 151 arranged sequentially along the height of the inspection plate 15. A dustproof grille 14 is fixedly installed on the side of the inspection plate 15 outside the housing 1, at the location of the ventilation opening. The dustproof grille 14 extends downwards at an angle, and multiple dustproof grilles 14 are provided, each corresponding to a ventilation opening 151 on the inspection plate 15. The dustproof grille 14 prevents dust in the air from naturally accumulating and entering the housing 1 through the ventilation openings 151.

[0049] In some embodiments, the dustproof heat dissipation box for electrical equipment also includes a dustproof net 13. The inspection plate 15 has mounting holes, and the dustproof net 13 is installed at the mounting holes. The dustproof net 13 is located inside the box 1 and is installed vertically. The dustproof net 13 has filter holes that communicate with the ventilation openings 151 on the box 1 and the inspection plate 15. The dustproof net 13 can filter dust and prevent external dust from entering the box 1.

[0050] In some embodiments, the dustproof heat dissipation box for electrical equipment also includes a limiting component, which is used to limit the inspection plate 15 at the opening of the box body 1. The limiting component includes an operating member 9, a first locking member 10, a second locking member 11, and an elastic member 12. A through hole is provided on the upper side of the box body 1, which passes through the upper and lower surfaces of the upper side of the box body 1 and extends vertically. The operating member 9 is slidably disposed in the through hole of the box body 1 in the vertical direction. The first locking member 10 is disposed at the lower part of the operating member 9. One end of the elastic member 12 is connected to the operating member 9, and the other end of the elastic member 12 is connected to the upper inner wall of the box body 1. The second locking member 11 is connected to the side of the inspection plate 15 located inside the box body 1 facing the cooling fan 7, and the second locking member 11 is used to engage with the first locking member 10.

[0051] When the second card connector 11 engages with the first card connector 10, both the second card connector 11 and the first card connector 10 are located inside the housing 1; when the second card connector 11 separates from the first card connector 10, the first card connector 10 is located inside the housing 1, and the second card connector 11 is located outside the housing 1.

[0052] See Figure 9 One of the first latching member 10 and the second latching member 11 is an annular slot, and the other is an annular protrusion that can be inserted into the annular slot. The operating member 9 includes a body and an operating part disposed on the upper side of the body. The operating part is always located outside the housing 1. The first latching member 10 is disposed on the side of the body away from the operating part. The body is convex in shape, and the operating part is strip-shaped.

[0053] The specific implementation method of the limiting component in this example is as follows:

[0054] Press down the operating component 9 to move the first locking component 10 downward, releasing the engagement between the first locking component 10 and the second locking component 11. At this time, the inspection plate 15 can be rotated and laid down, opening the hole, and the dustproof grid 14 and dustproof net 13 set on the inspection plate 15 can be cleaned and maintained. After cleaning, press down the operating component 9 to move the first locking component 10 downward, rotate the inspection plate 15 to close, release the handle, and under the elastic contraction of the elastic component 12, the first locking component 10 moves upward until it engages with the second locking component 11 again, completing the fixation of the inspection plate 15. A limit component is provided to facilitate the operation of the inspection plate 15. The inspection plate 15 is rotated and laid down, at which time the dustproof grille 14, the vent, and the dustproof net 13 on the inside of the inspection plate 15 can be cleaned and maintained. After cleaning and maintenance are completed, the inspection plate 15 is rotated back. Compared with the traditional structure design that only passively prevents dust from the vent through the dustproof grille 14, by disassembling the inspection plate 15, the dustproof net 13 and the dustproof grille 14 can be quickly opened to clean the dustproof grille 14 and the dustproof net 13 on the inspection plate 15. This effectively improves the maintainability of the dustproof structure and extends its service life.

[0055] In this example, the upper end of the inspection plate 15 has a first plane, a second plane, and a connecting surface connecting the first plane and the second plane. The first plane is higher than the second plane and is set outwards from the second plane, which is conducive to the rotation of the inspection plate.

[0056] A temperature sensor 17 is installed on the side of the heat-conducting partition 2 facing the heat-conducting frame 3. The temperature sensor 17 can monitor the temperature of the heat-conducting partition 2 in real time. As the power distribution unit operates, the generated heat will continuously accumulate on the heat-conducting partition 2 along the heat-conducting connecting plate 5 and the heat-conducting frame 3. When the temperature of the heat-conducting partition 2 is detected to rise to the set temperature value, the temperature sensor 17 can feed the information back to the control terminal, and the control terminal will issue a command to control the cooling fan 7 to work. When the temperature of the heat-conducting partition 2 drops below the set temperature value, the temperature sensor 17 will also feed the information back to the control terminal, and the control terminal will issue a command to control the cooling fan 7 to stop working, thereby realizing automated heat dissipation.

[0057] The working principle of the dustproof heat dissipation box in this example is as follows: During the use of the heat dissipation box, as the power distribution unit operates, heat will accumulate. The generated heat will be transferred along the heat-conducting connecting plate, heat-conducting frame, heat-conducting pipe, and heat-conducting plate in contact with the power distribution unit to the heat-conducting partition, and finally dispersed and conducted to multiple heat sinks on the back of the heat-conducting partition. As the heat continues to accumulate, the temperature on the heat-conducting partition will reach the set value of the temperature sensor. At this time, the sensor will feed back the temperature information to the control terminal, and the control terminal will control the cooling fan to work. The cooling fan on one side will circulate room temperature air along... The airflow is directed from one side of the vent into the enclosure and then rapidly expelled from the enclosure through the other side's vent, creating a rapid airflow. Guided by the heat-conducting grooves on the heat sink, the rapidly flowing air quickly carries away the heat from the heat sink. The heat on the heat-conducting partition is also quickly conducted away, causing the temperature of the partition to drop. When the temperature drops below the set value of the temperature sensor, the temperature sensor sends the temperature information back to the control terminal, which then stops the cooling fan, completing the overall cooling operation of the equipment.

[0058] The advantages of the dustproof heat dissipation box for electrical equipment in this example are:

[0059] Compared to traditional dust boxes for electrical equipment that use air cooling, this device utilizes heat conduction methods such as heat conduction racks, heat conduction pipes, heat conduction plates, heat conduction partitions, and heat sinks to more efficiently transfer the heat generated by the power distribution unit to the heat conduction components. Furthermore, compared to traditional heat dissipation areas that only have a portion of the equipment in contact with the air, the combination of heat sinks and heat conduction channels significantly increases the heat dissipation area, further improving heat dissipation efficiency. This combination of more efficient heat conduction and a larger heat dissipation area effectively enhances the heat dissipation efficiency of the enclosure.

[0060] Inspection panels are installed on both sides of the enclosure, with dust grilles, vents, and dust filters mounted on them. When the dust filters become clogged with dust, affecting the heat dissipation of the structure, the operator can use the limiting components to rotate and lower the inspection panels, and then clean and maintain the dust grilles, vents, and the dust filters inside the inspection panels. After cleaning and maintenance, the inspection panels are rotated back to their initial position. Compared to the traditional structure that passively prevents dust from entering the vents using only dust grilles, the addition of dust filters and the quick-opening design of the overall dustproof structure effectively improves the maintainability and service life of the dustproof structure.

[0061] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
