Description

Technical Field

[0001] The present invention relates to the technical field of UPS power supplies, and particularly to a UPS power supply device with a moisture-proof and humidity-proof structure. Background Art

[0002] UPS refers to a power supply device that will not be interrupted by a short-term power outage, can continuously supply high-quality power, and effectively protect precision instruments. It has the function of stabilizing voltage and is similar to a voltage stabilizer. In terms of the basic application principle, UPS is a power protection device containing an energy storage device, with an inverter as the main component, and outputs a stabilized voltage and frequency. It mainly consists of a rectifier, a battery, an inverter, and a static switch, etc. The most commonly used one is the standby UPS, which has functions such as automatic voltage regulation and power failure protection. Although it generally has a conversion time of about 10 ms and the alternating current output by the inverter is a square wave rather than a sine wave, due to its simple structure, it has the advantages of low price and high reliability, so it is widely used in fields such as microcomputers, peripherals, and POS machines. Its main body is similar to a mainframe chassis, and a rectifier, a battery, an inverter, and a static switch, etc. are installed inside. An external battery interface, an RS-232 communication interface, a smart slot, a USB communication interface, a fan, an input power circuit breaker, and output / input terminals are also installed on the chassis.

[0003] During the process of using an uninterruptible power supply system, one of the reasons for the failure of the UPS host is that dust is brought into the machine and deposited. When the air is humid, it will cause the host control to be disordered, resulting in the abnormal operation of the host and inaccurate alarms. A large amount of dust will also cause poor heat dissipation of the components. Generally, it should be thoroughly cleaned once every quarter.

[0004] The above information disclosed in the background art section is only used to enhance the understanding of the background of the present disclosure, so it may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0005] The object of the present invention is to design a UPS power supply device that can reduce the humidity of humid air, prevent moisture and humidity, and to a certain extent reduce the entry of dust, and at the same time dissipate heat from the electronic components that generate heat during operation, so as to solve the above deficiencies in the technology.

[0006] To achieve the above object, the present invention provides the following technical solution: A UPS power supply device with a moisture-proof and moisture-resistant structure, including a chassis, a rectifier, a battery, an inverter, a static switch and an intake fan are installed inside the chassis. A partition board is fixedly installed inside the chassis, and the partition board divides the inside of the chassis into a ventilation chamber and an installation chamber. A compressor, a condenser and an evaporator are installed in the ventilation chamber. The intake fan and the evaporator are installed at the air inlet of the ventilation chamber, and the condenser is installed at the air outlet of the ventilation chamber. A spiral conveyor is installed in the installation chamber. The output end and the input end of the spiral conveyor are respectively fixedly installed with an output pipe and an input pipe. Both the output pipe and the input pipe are braided pipes with braided holes. The spiral conveyor, the input pipe and the output pipe are filled with dehumidifying and drying particles. The evaporator is located between the input pipe and the intake fan, and the evaporator is in contact with the braided pipe.

[0007] The cold air and the separated moisture emitted by the evaporator are blown by the fan towards the input pipe. The dehumidifying and drying particles in the input pipe absorb the moisture and are moved by the spiral conveyor to the output pipe. The cold air absorbs the heat emitted during the operation of the equipment in the ventilation chamber and then warms up. When it is discharged at the air outlet of the ventilation chamber, it dries the dehumidifying and drying particles with moisture in the output pipe.

[0008] Preferably, the spiral conveyor includes a cylindrical outer shell fixedly installed on the partition board, a connecting shaft rotatably connected inside the cylindrical outer shell, a spiral blade fixedly installed outside the connecting shaft, and a motor and a speed-changing gear box installed in the installation chamber. The output end of the speed-changing gear box is fixedly connected to the connecting shaft, and the output end of the motor is fixedly connected to the input end of the speed-changing gear box.

[0009] Preferably, the input pipe as a whole is repeatedly bent in a snake shape to form a rectangular plane pattern. The area of the rectangular plane is larger than the cross-sectional area of the evaporator, and the outer walls of the input pipe are in contact with each other.

[0010] Preferably, the output pipe as a whole is repeatedly bent in a snake shape to form a rectangular plane pattern. The area of the rectangular plane is larger than the cross-sectional area of the condenser, and the output pipe completely covers the air outlet of the ventilation chamber.

[0011] Preferably, both the input pipe and the output pipe are braided pipes made of metal. The aperture of the braided holes on the braided pipe is smaller than the diameter of the dehumidifying and drying particles; this can prevent the dehumidifying and drying particles from falling out of the braided holes. Due to the existence of the braided holes, gas can pass through the input pipe and the output pipe, and at the same time, the water droplets separated by the evaporator can also be blown by the wind of the fan through the braided holes and come into contact with the dehumidifying and drying particles.

[0012] Preferably, the compressor is installed at the air outlet of the ventilation chamber, and the rectifier, battery, inverter, and static switch are installed at the air inlet of the ventilation chamber.

[0013] Preferably, a first filter screen and a second filter screen are fixedly installed on the top of the chassis. The first filter screen is installed at the air outlet of the ventilation chamber, and the second filter screen is installed on the top of the installation chamber; the first filter screen prevents external objects from directly falling onto the condenser, and the second filter screen allows the installation chamber to communicate with the outside, enabling the part where the input pipe and the output pipe are connected to dissipate heat through air cooling with the outside.

[0014] In the above technical solution, the technical effects and advantages provided by the present invention are as follows:

[0015] This product cools the incoming air in advance through the evaporator, causing the air to precipitate moisture. Then, the air is blown through the dehumidifying and drying particles by the fan, enabling the moisture to be absorbed in advance, thus avoiding the problem of the host control being disordered due to humid air in the prior art.

[0016] When the dehumidifying and drying particles absorb moisture, they will adhere to a certain amount of dust. Then, when the dehumidifying and drying particles are dried in the discharge pipe, the viscosity decreases, and the dust will be directly blown out of the chassis, thereby reducing part of the dust entering the chassis and further reducing the possibility of the host control being disordered, and extending the cycle of thorough cleaning.

[0017] Through the cooperation among the screw conveyor, the input pipe, and the output pipe, after the dehumidifying and drying particles absorb moisture, they are dried to remove moisture by using the hot air discharged at the air outlet of the ventilation chamber, and then return to the air inlet of the ventilation chamber to absorb the moisture in the air and the precipitated water, forming a cycle.

[0025] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of this application.

[0026] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0027] The present invention provides as Figures 1-4A UPS power supply device with a moisture-proof and moisture-resistant structure as shown includes a chassis 1. Inside the chassis 1, a rectifier 2, a storage battery 3, an inverter 4, a static switch 5, and an intake fan 6 are installed. A partition plate 7 is fixedly installed inside the chassis 1. The partition plate 7 divides the inside of the chassis 1 into a ventilation chamber 8 and an installation chamber 9. A compressor 10, a condenser 11, and an evaporator 12 are installed in the ventilation chamber 8. The intake fan 6 and the evaporator 12 are installed at the air inlet of the ventilation chamber 8, and the condenser 11 is installed at the air outlet of the ventilation chamber 8. A spiral conveying device 13 is installed in the installation chamber 9. The spiral conveying device 13 includes a cylindrical outer shell 13a fixedly installed on the partition plate 7, a connecting shaft 13b rotatably connected inside the cylindrical outer shell 13a, a spiral blade 13c fixedly installed outside the connecting shaft 13b, and a motor 13d and a speed-changing gearbox 13e installed in the installation chamber 9. The output end of the speed-changing gearbox 13e is fixedly connected to the connecting shaft 13b, and the output end of the motor 13d is fixedly connected to the input end of the speed-changing gearbox 13e. The output end and the input end of the cylindrical outer shell 13a are respectively fixedly installed with an output pipe 14 and an input pipe 15. Both the output pipe 14 and the input pipe 15 are braided pipes with braided holes, such as those made of copper wire braiding. The input pipe 15 is integrally formed into a rectangular plane pattern by repeatedly bending in a snake shape. The area of the rectangular plane is larger than the cross-sectional area of the evaporator 12. The outer walls of the input pipe 15 are in contact with each other. The output pipe 14 is integrally formed into a rectangular plane pattern by repeatedly bending in a snake shape. The area of the rectangular plane is larger than the cross-sectional area of the condenser 11, and the output pipe 14 completely covers the air outlet of the ventilation chamber 8. The cylindrical outer shell 13a, the input pipe 15, and the output pipe 14 are filled with dehumidifying and drying particles 16. The dehumidifying and drying particles 16 are those that can absorb water without swelling and can be reused after drying, such as silica gel desiccant and carbon oxygen desiccant. Both the input pipe 15 and the output pipe 14 are braided pipes made of metal. The aperture of the braided holes on the braided pipe is smaller than the diameter of the dehumidifying and drying particles 16. The evaporator 12 is located between the input pipe 15 and the intake fan 6, and the evaporator 12 is in contact with the braided pipe.

[0028] During operation, the rectifier 2, battery 3, inverter 4, compressor 10, and condenser 11 generate heat, while the evaporator 12 absorbs heat. When the fan is operating, it blows external air into the system. As the air passes through the evaporator 12, it is cooled and the moisture in the air condenses on the fins of the evaporator 12. The wind generated by the fan blows the water and cold air deposited on the fins towards the input pipe 15 that is closely attached to the evaporator 12. The water and cold air enter through the woven holes and, when passing through the dehumidifying and drying particles 16, the moisture is absorbed, causing dust in the air to adhere to the surface of the initially dry particles with moisture. Then, the dry and cold air passing through the input pipe 15 enters the ventilation chamber 8 to dissipate heat from the electronic components and other components operating inside. Finally, the cold air heats up and is blown towards the output pipe 14 and discharged from the chassis 1. When the motor 13d is operating, it drives the variable speed gearbox 13e to adjust the rotational speed, which then drives the connecting shaft 13b to rotate. The connecting shaft 13b drives the helical blade 13c to rotate, and the helical blade 13c drives the dehumidifying and drying particles 16 with moisture inside the cylindrical housing 13a into the discharge pipe. The dehumidifying and drying particles 16 with moisture in the discharge pipe are dried by the hot air flow discharged from the ventilation chamber 8, and some of the dust adhering to the surface of the initially dry particles is also blown out of the chassis 1. The dehumidifying and drying particles 16 after drying the moisture are air-cooled in the installation chamber 9 and then squeezed into the input pipe 15 to absorb the moisture blown by the fan. Finally, the dehumidifying and drying particles 16 with moisture in the input pipe 15 are squeezed into the cylindrical housing for circulation.

[0029] Importantly, it should be noted that the construction and arrangement of the present application shown in multiple different exemplary embodiments are merely illustrative.
