Detailed Description
The embodiment of the invention discloses a heat-dissipation efficient power distribution cabinet, which aims to solve the problems of low heat-dissipation efficiency and high heat-dissipation dust-removal energy consumption of the power distribution cabinet in the prior art.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
as shown in fig. 1 to 7, the invention provides a heat dissipation efficient power distribution cabinet, which comprises a circuit bin 1, a heat dissipation bin 2 and a shaking dust removal device 3, wherein a heat dissipation port 11 is formed in the side wall of the circuit bin 1, and the shaking dust removal device 3 is arranged on one side of the heat dissipation port 11, which is located in the circuit bin 1; and the shaking dust removing device 3 comprises a dust collecting shaking plate 31 and a dust box 32 located below the dust collecting shaking plate 31 for collecting dust shaken off by the dust collecting shaking plate 31.
The invention is characterized in that intermittent negative pressure generated by the heat dissipation bin 2 is utilized to provide shaking power for the shaking dust removal device 3. And the negative pressure is used for guiding the air in the heat dissipation bin 2 to circulate. Specifically, the method comprises the following steps:
the heat dissipation bin 2 is communicated with the shaking dust removal device 3 through an air path, the heat dissipation bin 2 comprises a negative pressure cavity 22 which generates intermittent negative pressure through a power device 21, the negative pressure cavity 22 is fixedly connected with a dust collection shaking plate 31 through a negative pressure air suction pipe 23, and the dust collection shaking plate 31 is shaken intermittently through the intermittent negative pressure generated by the negative pressure air suction pipe 23 through the negative pressure cavity 22.
And the negative pressure chamber 22 also guides the airflow of the dust attached in the circuit compartment 1 through the dust collecting shaker plate 31 to be collected through the airflow duct 24.
Example two:
although the negative pressure cavity 22 can generate intermittent negative pressure to intermittently dissipate heat in the circuit bin 1 from the heat dissipation bin 2, circuit elements in the negative pressure cavity 22 are in a continuous working state, and if the generated heat cannot be continuously dissipated, the power distribution cabinet is in a fault, the work is suspended, even a circuit burns out, and personal safety is damaged. How to make the power distribution cabinet in the process of continuous heat dissipation is a difficult point to be solved by the invention. The invention adopts a mode that a plurality of heat dissipation bins 2 work alternately, thus solving the problems. Specifically, the method comprises the following steps:
the gas division plate 25 which divides the heat dissipation bin 2 into two negative pressure cavities 22 is movably arranged in the heat dissipation bin 2, and the two negative pressure cavities 22 are respectively connected with a shaking dust removal device 3.
When the gas separation plate 25 moves radially along the cross section of the heat dissipation chamber 2 under the pushing action of the power device 21, the gas pressure in the two negative pressure chambers 22 separated by the gas separation plate 25 changes. One of the negative pressure cavities 22 is gradually enlarged in volume to generate negative pressure, and the negative pressure cavity 22 absorbs heat in the circuit bin 1 into the negative pressure cavity 22 through the airflow pipe 24; the volume of the other negative pressure chamber 22 is gradually reduced, and the heat absorbed before this negative pressure chamber 22 is discharged to the outside of the heat dissipation chamber 2. Thereby, the heat dissipation process of the circuit bin 1 is realized. The two negative pressure cavities 22 alternately absorb heat and emit heat, so that the continuity of the heat radiation process is realized. Specifically, the method comprises the following steps:
the airflow pipes 24 connected with the two negative pressure cavities 22 are respectively provided with a one-way air inlet valve 26, and air can only enter the negative pressure cavities 22 from the airflow pipes 24 but can not flow out of the airflow pipes 24 from the negative pressure cavities 22, so that the one-way flowability of the circuit bin 1 with absorbed heat is ensured.
Both negative pressure chambers 22 are connected with one-way exhaust valves 27 extending to the outside of the negative pressure chambers 22. The heat can only flow out of the negative pressure cavity 22, but can not absorb the air outside the negative pressure cavity 22, thereby ensuring the unidirectional fluidity of the heat dissipation.
Example three:
one of the features of the invention is also: the dust collection shaking plate 31 is intermittently shaken by the intermittent negative pressure generated through the negative pressure chamber 22 by the negative pressure suction pipe 23. Specifically, the method comprises the following steps:
the dust-collecting shaking plate 31 includes an elastic frame 311, and the elastic frame 311 has elasticity to facilitate shaking effect. A plurality of dust collecting cloth bag cylinders 312 for collecting dust are distributed on the elastic net rack 311, and the dust collecting cloth bag cylinders 312 can adsorb dust attached to heat flow entering the dust collecting cloth bag cylinders 312 from the circuit bin 1, so that the dust collecting effect is enhanced.
Further, an adsorption air chamber 313 is provided on one side of the elastic net frame 311 near the heat dissipating port 11, and preferably, the cross section of the adsorption air chamber 313 is larger than that of the negative pressure air suction pipe 23, so as to generate a large adsorption force to the elastic net frame 311, thereby shaking the elastic net frame 311. And the negative pressure suction pipe 23 communicates with the inside of the suction air chamber 313.
The negative pressure suction pipe 23 is detachably attached to the suction air chamber 313 to facilitate a separate cleaning process for the dust collecting shaker plate 31 at a later stage.
Preferably, the adsorption air chambers 313 are provided at the same level on the elastic net frame 311. So that the stress of the elastic net rack 311 on the same plane is relatively uniform, and the stability of the elastic net rack 311 during shaking is improved.
The dust collecting shaking plate 31 is inclined from the side far from the heat dissipation port 11 to the side near the heat dissipation port 11 from the bottom to the top. So that the dust on the dust-collecting cloth bag cylinder 312 can smoothly enter the dust box 32 located therebelow after shaking.
Example four:
the negative pressure chamber 22 of the present invention also guides the airflow of the dust attached in the circuit compartment 1 through the dust collecting shaker plate 31 to be collected by the airflow duct 24. Specifically, the method comprises the following steps:
the airflow pipe 24 includes a plurality of air suction ports 241, the air suction ports 241 are uniformly distributed on a plane, the air inlet ends of the air suction ports 241 are all opposite to the dust collecting shaking plate 31, and the projection of the plane formed by the air suction ports 241 on the dust collecting shaking plate 31 is not smaller than that of the dust collecting shaking plate 31. The mode can make the flow of the relatively uniform heat flow on the dust collecting shaking plate 31, avoid the uneven heat flow and the uneven heat dissipation, or the dust attached with the heat flow is rapidly gathered at the local part of the dust collecting shaking plate 31, and the service life of the local dust collecting shaking plate 31 is prolonged.
Since the air flow pipe 24 is connected to the negative pressure chamber 22, a short negative pressure can be generated on the side of the dust shaking plate 31 near the heat radiating port 11. The negative pressure has the following obvious effects on the heat dissipation process:
firstly, heat in the circuit cabin 1 is guided to the inner side of the dust collecting shaking plate 31, so that the dust collecting shaking plate 31 can conveniently collect dust in the circuit cabin 1 in a centralized manner;
the negative pressure can also gather the negative pressure of the circuit bin 1 to the vicinity of the airflow pipe 24, so that the heat dissipation bin 2 can absorb and dissipate heat outwards;
in order to prevent the dust entering the dust collecting box 32 from flying again by the negative pressure, the dust collecting efficiency is reduced. The upper end of the dust box 32 is provided with a one-way filter screen 33, and dust falling into the dust box 32 from the one-way filter screen 33 cannot reversely pass through the one-way filter screen 33 to raise dust to the outside of the dust box 32.
As a preferred embodiment, the heat dissipation opening 11 and the air flow pipe 24 can be designed in a matching manner, so that on one hand, the equipment can be simplified, and on the other hand, the circulation efficiency of the air can be improved. Specifically, the method comprises the following steps:
the thermovent 11 includes a plurality of wind separation plates 111 and ventilative groove 112 that set up at the interval in proper order, and the outside wind of switch board gets into the inside of shake dust collector 3 through ventilative groove 112, then gets into the inside of circuit compartment 1 for the heat dissipation to circuit compartment 1 circuit element.
The air baffle 111 has air intake grooves 113 opened toward the dust collecting shaking plate 31, and the air intake grooves 113 are all in air communication with the airflow pipe 24. The negative air is emitted from the suction groove 113.
Furthermore, the heat dissipation opening 11 on the side close to the shaking dust removing device 3 is hinged with a wind shield 114 capable of shielding the ventilation slot 112, and the two wind shields 114 are linked with each other. Specifically, the method comprises the following steps:
when the wind shield 114 is acted by negative air on one side close to the dust collecting shaking plate 31, the wind shield 114 can cover the square wind-penetrating groove 112, so that the guiding effect of the negative air on heat flow is enhanced, and the situation that the external air enters the shaking dust removing device 3 to be weakened and the heat adsorption effect of the negative air is avoided. At this time, the wind shield 114 located on one side of the other shaking dust removing device 3 does not shield the ventilating slot 112, so that cold airflow located outside the power distribution cabinet enters the circuit cabin 1, and heat loss in the circuit cabin 1 is compensated.
The two wind deflectors 114 are linked to each other by a link (not shown in the figure), and when one wind deflector 114 is shifted, the other wind deflector 114 is shifted.
Preferably, a filter float net 115 for shaking off dust attached thereto by an air flow is loosely provided on a side of the heat emission port 11 adjacent to the dust collecting shaking plate 31, and the filter float net 115 is used for preventing dust from flowing out of the heat emission port 11 and attaching to the heat emission port 11. The filtering floating net 115 can also prevent external dust from entering the inside of the power distribution cabinet through the heat dissipation port 11.
Further, the heat dissipation opening 11 is inclined from the side close to the dust collecting shaking plate 31 to the side close to the dust collecting shaking plate 31 from the bottom to the top, which is beneficial to the dust on the filtering floating net 115 falling into the dust collection box 32. Keeping the vicinity of the heat dissipation opening 11 unblocked.
In the above, the heat dissipation efficient power distribution cabinet provided by the present invention is described in detail, and for a person skilled in the art, according to the idea of the embodiment of the present invention, there may be changes in the specific implementation manner and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
