Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

As shown in fig. 1, the cabinet includes cabinet body 10 and heat dissipation dust removal drying system, and cabinet body 10 is the cuboid cabinet body of being made by the cold-rolled steel sheet, and two adjacent panel junctions of cabinet body 10 use the rubber seal strip to carry out sealing treatment, and the front of cabinet body 10 is provided with cabinet door 11, is provided with the hasp on the cabinet door 11. The top of the cabinet body 10 is provided with two exhaust ports 12, and the lower part of the side wall of the cabinet body 10 is provided with two air inlets 13, of course, the number of the exhaust ports 12 and the number of the air inlets 13 are not limited thereto, and the number and the size of the exhaust ports 12 are specifically determined according to the heat dissipation capacity of the equipment inside the cabinet. When the cabinet door 11 is closed, the latch is locked, and the air inside the cabinet body 10 is mainly exchanged with the outside air through the air outlet 12 and the air inlet 13.

As shown in fig. 2, the heat dissipation, dust removal and drying system includes a main control circuit board 21, two exhaust fans 22 and two dust removal and drying devices 23, wherein the two exhaust fans 22 are respectively installed in the two exhaust ports 12. When the temperature in the cabinet is low, the exhaust fan 22 does not work, at this time, air is mainly conveyed into the cabinet by the intake fan 232, the air pressure in the cabinet is increased, and the hot air gathered at the top of the cabinet is exhausted out of the cabinet by the air pressure; when the temperature in the cabinet is higher than the preset temperature, the exhaust fan 22 starts to work, and the hot air in the cabinet is exhausted out of the cabinet through the exhaust fan 22, so that the equipment in the cabinet can be cooled better. As shown in fig. 3, in order to protect the exhaust fan 22, a metal mesh is further installed at the outlet of each exhaust port 12, and the metal mesh can effectively prevent objects from falling into the exhaust ports 12, which affects the normal operation of the exhaust fan 22. The dust removing and drying device 23 is used for removing dust and drying the outside air, and inputting the air after dust removal and drying into the cabinet body 10. The dust removing and drying device 23 comprises an air duct 231, an air inlet fan 232, a dust removing filter plate 233 and a drying filter screen 234, wherein the air duct 231 is of a tubular structure, and one end of the air duct 231 is communicated with the air inlet 13 through a screw. The air inlet fan 232, the dust removing filter plate 233 and the drying filter screen 234 are respectively arranged in the air duct 231, the air inlet fan 232, the dust removing filter plate 233 and the drying filter screen 234 are sequentially arranged in a direction away from the air inlet 13, the specific installation mode is that two insertion openings are formed in the side wall of the air duct 231, correspondingly, a clamping groove formed by annular blocking pieces is formed in the inner wall of the air duct 231, and the dust removing filter plate 233 and the drying filter screen 234 are inserted into the clamping groove in the air duct 231 through the insertion openings. The dust removing filter 233 is a porous hard sponge in this embodiment, and after the air is filtered by the porous hard sponge, most of dust and impurities in the air can be effectively filtered. The drying filter 234 is used for removing most of water vapor in the air, and the drying filter 234 is coated with a renewable solid desiccant, and the renewable solid desiccant comprises silica gel, molecular sieve or activated alumina. Because the mode of the solid desiccant that can regenerate to absorbing the moisture is the physical adsorption mode, when the drying filter 234 uses the drying function to reduce for a period of time, can take out drying filter 234, use drying apparatus to dry drying filter 234, make the moisture in drying filter 234 release, alright realize reusing, through using the solid desiccant that can regenerate, realize drying filter 234's used repeatedly, reduce use cost. The thickness of the dry filter 234 can be determined according to the moisture content of the air in the use place, and when the air humidity is high, the dry filter 234 with the thicker thickness can be used, so that the time of the humid air passing through the interior of the dry filter 234 is prolonged, and the dewatering effect is enhanced. Because increased dust removal cassette 233 and drying filter 234, increased the windage that the air got into in the rack, consequently need use inlet fan 232 to the rack in the air delivery, with former passive air inlet, become present initiative air supply, make inside more air admission racks, reinforcing cooling effect, in the use of whole rack, inlet fan 232 all is in the work and changes the attitude. By drying and dedusting the air entering the cabinet, the influence of dust and moisture on the equipment is avoided.

As shown in fig. 4, the main control circuit board 21 is disposed in the cabinet body 10, preferably disposed at the top of the cabinet body 10, and wrapped by a plastic box with an insulating function, and the plastic box is provided with a plurality of through holes to ensure that air in the cabinet can circulate with air in the plastic box, so that the temperature detection module 212 can accurately measure the temperature in the cabinet. The main control circuit board 21 is provided with a control module 211, a temperature detection module 212, a first relay 213, a buzzer 214 and a power module 215, wherein the control module 211 is electrically connected with the temperature detection module 212, the first relay 213, a second relay 216, the buzzer 214 and the power module 215, the exhaust fan 22 is electrically connected with the first relay 213, and the intake fan 232 is electrically connected with the second relay 216. The power module 215 is a power adapter in this embodiment, and is used to convert 220V ac power into 5V dc power for each module. The model of temperature detection module 212 is EM2318TC, and temperature detection module 212 is used for measuring the temperature value in the rack and converts it into the signal of telecommunication and sends to control module 211, and control module 211 is the singlechip in this embodiment, and the model of singlechip is STM32F103, and this model singlechip has the energy consumption low, advantage that the performance is stable. The control module 211 is configured to compare the measured temperature value with a preset temperature value, and control the exhaust fan 22 to operate and stop according to the comparison result, and when the measured temperature value is lower than the preset temperature value, the control module 211 controls the exhaust fan 22 to stop operating; when the measured temperature value is higher than the preset temperature value, the control module 211 controls the exhaust fan 22 to start working, the hot air in the cabinet is exhausted out of the cabinet through the exhaust fan 22, and meanwhile, the control module 211 also drives the buzzer 214 to alarm to prompt a user that the temperature in the cabinet is too high; the exhaust fan 22 and the air inlet fan 232 can be intelligently controlled by arranging the main control circuit board 21, and the energy consumption of the cabinet is effectively reduced.
