Description

Technical Field

[0001] This utility model relates to the field of power cabinet technology, and in particular to a heat dissipation and ventilation component for power cabinets. Background Technology

[0002] Power distribution cabinets (such as switchboards and control cabinets) are critical equipment used for power distribution, equipment protection, and automated control in industries such as industrial, energy, and building sectors. During operation, the electronic components inside the power distribution cabinet, such as circuit breakers, frequency converters, PLCs, and transformers, generate heat. If this heat cannot be effectively dissipated, the internal temperature of the cabinet will rise, leading to problems such as overheating, performance degradation, shortened lifespan, and even equipment failure and shutdown. Therefore, heat dissipation and ventilation components are one of the core elements in power distribution cabinet design, directly affecting the reliability, safety, and operating efficiency of the equipment.

[0003] In existing technologies, vertical dust filters are usually installed inside the power cabinet to block dust from entering. Although they can prevent some dust from entering, most of them cannot be automatically removed. The dust filters need to be manually removed for cleaning and then reinstalled, which leads to serious dust accumulation on the dust filters, reducing ventilation and heat dissipation inside the power cabinet. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the dustproof net cannot automatically remove dust, resulting in reduced ventilation and reduced heat dissipation in the power cabinet, and to propose a heat dissipation and ventilation component for power cabinets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heat dissipation and ventilation component for an electrical cabinet includes a cabinet body. A first shell and a second shell are disposed within the cabinet body, and the first and second shells are connected to form a heat dissipation channel. The first shell has an air inlet slot communicating with the heat dissipation channel. An inclined dustproof net is disposed on the side wall of the second shell, and a dust removal component is disposed on the dustproof net. An air supply channel is disposed on the first shell, corresponding to the air inlet slot. One end of the air supply channel extends into the cavity of the heat dissipation channel and is rotatably connected to a baffle. The other end of the air supply channel is provided with a first jet mechanism, the jetting end of which faces the air supply channel. A self-closing louver is disposed on the outer wall of the cabinet body. A second jet mechanism is disposed between the dustproof net and the self-closing louver, the jetting end of which faces the self-closing louver.

[0007] To facilitate the backflushing of dust in the heat dissipation channel, preferably, the first jet mechanism includes a first fan fixedly connected to the air inlet end of the air supply channel. When the first fan blows gas into the air supply channel, the baffle rotates and blocks the cavity opening of the heat dissipation channel.

[0008] To facilitate the connection and installation of the baffle, preferably, a rotating shaft is fixedly connected to the end corner of the air supply channel, and the baffle is rotatably connected to the rotating shaft.

[0009] To improve the shielding effect of the baffle, the coverage area of ​​the baffle is further greater than the cross-sectional area of ​​the air supply channel opening.

[0010] To facilitate the exhaust of hot air from inside the cabinet to the outside, preferably, the second jet mechanism includes a second fan fixedly connected inside the cabinet cavity, with the output end of the second fan facing the self-closing louver.

[0011] To improve the heat dissipation effect inside the cabinet, preferably, at least two sets of the second fan are provided, and multiple sets of the second fan are arranged at equal intervals along the length direction of the self-closing louvers.

[0012] Furthermore, the jet direction of the second fan is perpendicular to the plane of the self-closing louver.

[0013] To facilitate the vibration of dust on the dustproof screen and cause it to fall into the heat dissipation channel, the dust removal component preferably includes a vibration motor installed on the dustproof screen.

[0014] To facilitate the installation of the dustproof net, preferably, the second housing is positioned higher than the first housing.

[0015] In order for the baffle to block the cavity of the heat dissipation channel, preferably, the air duct of the second housing is a horizontal air duct, and the baffle is disposed in the horizontal air duct.

[0016] Compared with the prior art, the present invention provides a heat dissipation and ventilation component for a power cabinet, which has the following beneficial effects:

[0017] 1. The heat dissipation and ventilation component of the power cabinet, by activating the second jet mechanism, causes the jet end of the second jet mechanism to spray air towards the self-closing louvers, thereby spraying the hot air inside the cabinet to the outside, thus achieving the heat dissipation and ventilation effect, improving the ventilation effect of the cabinet, and ensuring the heat dissipation effect inside the power cabinet.

[0018] 2. The heat dissipation and ventilation component of this power cabinet can vibrate the dust on the dustproof screen by starting the vibration motor, so that the dust falls into the first shell for collection under the action of gravity;

[0019] 3. The heat dissipation and ventilation component of the power cabinet, by activating the first jet mechanism, allows the gas it sprays to blow the dust that falls into the first housing through the air inlet slot to the outside of the cabinet, thereby achieving the effect of automatic dust removal. There is no need to manually disassemble the dust screen, and it can also prevent dust accumulation on the dust screen, thereby improving the ventilation effect of the dust screen and the heat dissipation effect inside the cabinet.

[0020] The parts not mentioned in this device are the same as or can be implemented using existing technology. This utility model can blow the dust that falls into the first housing to the outside of the cabinet through the air inlet slot, thereby achieving the effect of automatic dust removal. There is no need to manually disassemble the dust screen, and it can also prevent dust accumulation on the dust screen, improve the ventilation effect of the dust screen and the heat dissipation effect inside the cabinet.

[0028] Example:

[0029] Reference Figures 1-4A heat dissipation and ventilation assembly for an electrical cabinet includes a cabinet 1, which houses electronic components such as circuit breakers, frequency converters, PLCs, and transformers. A first housing and a second housing are disposed within the cabinet 1, connected to form a heat dissipation channel 4. An air inlet slot 3, connected to the heat dissipation channel 4, is provided on the first housing to draw outside air into the channel. An inclined dustproof net 5 is provided on the side wall of the second housing. When the air inlet slot 3 introduces outside air into the heat dissipation channel 4, the inclined dustproof net 5 intercepts dust in the air. Simultaneously, the dustproof net 5 is positioned on the air inlet surface of the dustproof net 5. The cabinet is equipped with a dust removal component to vibrate and remove dust from the air inlet surface of the dustproof mesh 5, allowing the dust to fall into the first housing. Self-closing louvers 2 are installed on the outer wall of the cabinet 1. A second air jet mechanism is located between the dustproof mesh 5 and the self-closing louvers 2, with the jet nozzle facing the self-closing louvers 2. When the second air jet mechanism is activated, it can spray hot air from inside the cabinet 1 onto the self-closing louvers 2. At this time, the louvers on the self-closing louvers 2 will automatically rotate, opening up and expelling the hot air from inside the cabinet 1 to the outside, thus achieving heat dissipation and ventilation. A back-jet mechanism is also installed on the first housing. An air supply channel 7 is provided, and the air supply channel 7 is correspondingly set with the air inlet slot 3. One end of the air supply channel 7 extends into the cavity of the heat dissipation channel 4 and is rotatably connected to a baffle 9. When the air inlet slot 3 introduces external air into the heat dissipation channel 4, the baffle 9 will fall vertically under gravity, thus blocking the opening of the air supply channel 7. At this time, the gas will enter the cavity of the second housing. During this process, the dust filter 5 can intercept the dust in the air. The intercepted dust will fall into the first housing under gravity for centralized collection. In order to facilitate the backflushing of the collected dust, the other end of the air supply channel 7 is connected to the baffle 9. The first jet mechanism is provided at the end, with the jet end of the first jet mechanism facing the air supply channel 7. The first jet mechanism can jet air into the air supply channel 7. During this process, the baffle 9 will be blown up and the dust that falls into the first housing will be blown to the outside through the air inlet slot 3, thereby achieving the effect of cleaning the dust. This will block the cavity of the heat dissipation channel 4 and prevent the dust-laden air from re-entering the second housing, so that the air can only be blown to the outside through the air inlet slot 3. In addition, the position of the second housing is higher than that of the first housing, so that the dust can move downward under gravity. The air duct of the second housing is a horizontal air duct, and the baffle 9 is set in the horizontal air duct.

[0030] In the above scheme, by activating the second jet mechanism, the jetting end of the second jet mechanism is directed towards the self-closing louver 2 to spray air. The slats of the self-closing louver 2 are connected to the window via a pivot. When the second jet mechanism sprays air, the slats rotate, and the gas is ejected to the outside through the window. When the second jet mechanism stops spraying air, the slats automatically droop due to gravity, thus sealing the window and preventing external impurities from entering the cabinet 1. This allows the hot air inside the cabinet 1 to escape to the outside, achieving heat dissipation and ventilation, improving the ventilation effect of the cabinet 1, and ensuring the heat dissipation effect inside the power cabinet. This is achieved by activating vibration... The motor 6 can vibrate the dust on the dustproof net 5, causing the dust to fall into the first housing and be collected due to gravity. During this process, the baffle 9 always blocks the outlet of the air supply channel 7. By activating the first jet mechanism, air can be sprayed into the air supply channel 7. It should be explained that the jetting time of the first jet mechanism is between five and ten seconds. It can blow the dust that falls into the first housing to the outside of the cabinet 1 through the air inlet slot 3, thereby achieving the effect of automatic dust removal. There is no need to manually disassemble the dustproof net 5. It can also prevent dust accumulation on the dustproof net 5 and improve the ventilation effect of the dustproof net 5 and the heat dissipation effect inside the cabinet 1.

[0031] The aforementioned first jet mechanism includes a first fan 8 fixedly connected to the air inlet end of the air supply channel 7. When the first fan 8 blows gas into the air supply channel 7, the baffle 9 rotates and blocks the cavity opening of the heat dissipation channel 4. A rotating shaft is fixedly connected at the end corner of the air supply channel 7, and the baffle 9 is rotatably connected to the rotating shaft. When the first fan 8 is started, it can blow gas into the air supply channel 7, thereby rotating the baffle 9 and unsealing the cavity opening of the heat dissipation channel 4.

[0032] To improve the sealing effect of the baffle 9, the coverage area of ​​the baffle 9 is larger than the cross-sectional area of ​​the air supply duct 7.

[0033] Furthermore, the aforementioned second jet mechanism includes a second fan 10 fixedly connected within the cavity of the cabinet 1. The output end of the second fan 10 faces the self-closing louver 2, and the jet direction of the second fan 10 is perpendicular to the plane of the self-closing louver 2. It is used to transport the hot gas inside the cabinet 1, so that the air inlet slot 3 is in an air-inlet state. In order to improve the ventilation effect of the second fan 10, at least two sets of the second fan 10 are provided, and multiple sets of the second fan 10 are arranged at equal intervals along the length direction of the self-closing louver 2.

[0034] The aforementioned dust removal assembly includes a vibration motor 6 mounted on the dustproof net 5, which vibrates the dust on the dustproof net 5 so that the dust on the dustproof net 5 falls into the first housing when it is tilted.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
