Description

Technical Field

[0001] The present invention relates to the technical field of power distribution boxes, and more particularly to a waterproof and breathable communication base station power supply device. Background Art

[0002] The base station integrated power supply is a highly integrated power supply system designed for communication base stations. It integrates traditional decentralized power supply equipment (such as AC power distribution, rectifier modules, DC power distribution, batteries, monitoring units, etc.) into a compact and efficient solution. It aims to meet the needs of stable power supply for base station equipment and has the outstanding characteristics of high integration, high efficiency and energy saving, intelligent management and environmental adaptability.

[0003] In order to prevent the air inside the communication base station power supply equipment from becoming humid and affecting the normal and safe use of its internal electrical components, the air drawn into it needs to be dehumidified. One method of performing dehumidification is to install a semiconductor refrigeration plate at the air inlet of the communication base station power supply equipment so that the water vapor in the external humid air contacts the cold end of the semiconductor refrigeration plate and condenses, then converts into liquid and is finally discharged, thereby separating the water vapor from the humid air entering the communication base station power supply equipment.

[0004] The above-mentioned moisture-proof and dehumidification structure directly cools the humid air to condense and precipitate the water vapor therein. There is a risk of water vapor freezing in low-temperature areas, especially in high-humidity areas where the air contains a lot of moisture. The heat exchange efficiency is not high by directly condensing and liquefying the humid air, resulting in low water vapor separation efficiency in the humid air. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide a waterproof and breathable communication base station power supply equipment, which draws air from the external humid environment into the hot chamber through the exhaust part and enters the evaporation chamber for heating and evaporation. The high-temperature water vapor formed by evaporation enters the cold chamber for condensation, reducing the risk of freezing in the low-temperature area. The initial temperature difference between the high-temperature humid air and the cold chamber is larger, and the heat exchange efficiency is higher, thereby improving the water vapor separation efficiency.

[0056] The sealing block 43 is fixedly connected to the storage tube 5 by fastening bolts; a second annular filter screen 45 is fixed to the top of the sealing cover 41; a threaded ring 46 is screwed to the side surface of the second annular filter screen 45; a top cover 47 is fixed to the top of the threaded ring 46; an air supply channel 48 is formed between the top cover 47 and the sealing cover 41.

[0057] Partitions 49 are evenly fixed on the inner walls of the conical cover 9 and the isolation tube 8; serpentine heat exchange channels 50 are formed between the partitions 49; a liquid accumulation chamber 51 is formed between the isolation tube 8 and the heat-insulating tube 4; a drainage pipe 52 is evenly connected to the bottom surface of the liquid accumulation chamber 51; a control valve is provided on the drainage pipe 52; a floating plate 53 is slidingly provided inside the liquid accumulation chamber 51; a plurality of through holes 54 are opened on the surface of the floating plate 53; a pressure sensor 55 is installed on the side surface of the isolation tube 8; an electric heating tube 56 is installed on the inner wall of the liquid accumulation chamber 51.

[0058] A controller is installed inside the power distribution box 1. The output end of the controller is electrically connected to the control valve, exhaust fan, electric heating tube 56 and semiconductor refrigeration unit 12, and the input end of the controller is electrically connected to the pressure sensor 55. When the water in the liquid accumulation chamber 51 freezes, the electric heating tube 56 can be controlled to heat the liquid accumulation chamber 51 to melt it, thereby facilitating the discharge of the accumulated water.

[0059] Working principle of the second embodiment:

[0060] The exhaust fan is controlled to start and draw the external humid air into the exhaust pipe 42 through the air supply channel 48 and the second annular filter 45 (for filtering large particles of impurities in the air). The filtered humid air is dehumidified for the first time through the water-absorbing sponge block 44, and then enters the air inlet 29 through the first annular filter 30 (for filtering small particles of impurities in the air) and flows along the evaporation chamber 28. During this process, the moisture in the humid air is heated and evaporated, and the high-temperature humid air enters the cold chamber 7 through the exhaust pipe 31, the hose and the branch pipe 32 in turn for condensation, reducing the risk of freezing in the low-temperature area. The initial temperature difference between the high-temperature humid air and the cold chamber is larger, and the heat exchange efficiency is higher, thereby improving the water vapor separation efficiency.

[0061] The high-temperature humid air is blown toward the heat exchange fins 35 of the cooling disk 34 through the branch pipe 32, driving it to rotate. The condensed water is thrown from the surface of the cooling disk 34 to the liquid accumulation chamber 51 due to centrifugal force, effectively preventing the water on the cooling disk 34 from freezing, and further reducing the risk of freezing in the low-temperature area.

[0062] The condensed air passes through the waterproof and breathable membrane 11 and enters the serpentine heat exchange channel 50 for further cooling. The low-temperature air after dehydration is sent to the inside of the power distribution box 1 to exchange heat with the heat generated by the work inside the power distribution box 1. The air after heat exchange is discharged through the L-shaped exhaust pipe 16 to achieve cooling of the inside of the power distribution box 1 and prevent humid air from entering its interior and causing damage.

[0063] During the rotation of the cooling plate 34, the rotating shaft 33 and the reciprocating screw 37 are driven to rotate synchronously, thereby driving the filter press plate 39 to perform reciprocating lifting and lowering motion 1 along the sliding rod 38. When the filter press plate 39 rises, it slides into the filter screen cover 58 to squeeze the water-absorbing sponge block 44. After the water is squeezed out, it flows through the filter screen cover 58 and the filter plate 59 to the drain pipe 40 for discharge; during the descent of the filter press plate 39, the water-absorbing sponge block 44 is reset, so that the water-absorbing sponge block 44 can repeatedly absorb water from the humid air.

[0064] When the liquid level in the liquid accumulation chamber 51 gradually rises, the float plate 53 is driven to slide and rise along the inner wall of the liquid accumulation chamber 51. When the float plate 53 rises to against the pressure sensor 55, the pressure sensor 55 transmits a signal to the controller inside the power distribution box 1. The controller controls the corresponding control valve to open for a specified period of time and then automatically close, so that the accumulated water in the liquid accumulation chamber 51 is discharged through the drain pipe 52, thereby realizing automatic drainage of the liquid accumulation chamber 51 and improving the practicality of the device.
