Description

Technical Field

[0001] The invention relates to the technical field of UPS power supply, and in particular 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 power outage, can always supply high-quality power, and effectively protect precision instruments. It has the function of stabilizing voltage, similar to a voltage stabilizer. From the basic application principle, UPS is a power protection device that contains an energy storage device, uses an inverter as the main component, and outputs a stable voltage and frequency. It is mainly composed of several parts such as a rectifier, a battery, an inverter, and a static switch. The most commonly used one is the backup UPS, which has functions such as automatic voltage stabilization and power failure protection. Although it generally has a conversion time of about 10ms, and the AC output of the inverter is a square wave rather than a sine wave, it is widely used in microcomputers, peripherals, POS machines and other fields due to its simple structure, low price, and high reliability. Its main body is similar to the main chassis, with rectifiers, batteries, inverters, and static switches installed inside. External battery interfaces, RS-232 communication interfaces, smart slots, USB communication interfaces, fans, input power circuit breakers, and output / input terminals will also be installed on the chassis.

[0003] When using an uninterruptible power supply system, one of the causes of UPS host failure is dust being brought into the machine and deposited. When the air is humid, it will cause host control disorder, causing the host to malfunction and inaccurate alarms. A large amount of dust will also cause poor heat dissipation of the device. Generally, it should be thoroughly cleaned once a quarter.

[0004] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not constitute the prior art that is already known to one of ordinary skill in the art. Summary of the invention

[0005] The purpose 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 reduce dust entry to a certain extent, while dissipating heat from electronic components that generate heat during operation, so as to solve the above-mentioned deficiencies in the technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a UPS power supply device with a moisture-proof and moisture-proof structure, comprising a chassis, a rectifier, a battery, an inverter, a static switch and an inlet fan installed inside the chassis, a partition plate fixedly installed inside the chassis, the partition plate 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 inlet fan and the evaporator are installed at the air inlet of the ventilation chamber, the condenser is installed at the air outlet of the ventilation chamber, a spiral conveying device is installed in the installation chamber, an output pipe and an input pipe are fixedly installed at the output end and the input end of the spiral conveying device respectively, the output pipe and the output pipe are braided tubes with braided holes, the spiral conveying device, the input pipe and the output pipe are filled with dehumidification and drying particles, the evaporator is located between the input pipe and the inlet fan, and the evaporator and the braided tube are fitted; The cold air and the precipitated moisture from the evaporator are blown to the input pipe by a fan. The dehumidifying and drying particles in the input pipe absorb moisture and are moved to the output pipe by a spiral conveyor. The cold air absorbs the heat generated by the equipment when it is working in the ventilation chamber and heats up. When it is discharged from the air outlet of the ventilation chamber, the dehumidifying and drying particles with moisture in the output pipe are dried.

[0007] Preferably, the spiral conveying device includes a cylindrical shell fixedly mounted on the partition plate, a connecting shaft rotatably connected inside the cylindrical shell, a spiral piece fixedly mounted outside the connecting shaft, and a motor and a speed gear box installed in the installation chamber, wherein the output end of the speed 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 gear box.

[0008] Preferably, the input pipe is bent repeatedly in a serpentine shape as a whole 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 fit each other.

[0009] Preferably, the output pipe is serpentine-shaped and repeatedly bent to form a rectangular plane, 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.

[0010] Preferably, the input pipe and the output pipe are both braided pipes made of metal, and the diameter of the braided holes on the braided pipes is smaller than the diameter of the dehumidifying and drying particles; this can prevent the dehumidifying and drying particles from falling through the braided holes. Due to the presence of the braided holes, the gas can pass through the input pipe and the output pipe, and at the same time, the water droplets precipitated from the evaporator can also be blown through the braided holes by the wind blown by the fan and come into contact with the dehumidifying and drying particles.

[0011] 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.

[0012] Preferably, a first filter and a second filter are fixedly installed on the top of the chassis, the first filter is installed at the air outlet of the ventilation chamber, and the second filter is installed on the top of the installation chamber; the first filter prevents foreign objects from falling directly onto the condenser, and the second filter allows the installation chamber to be connected with the outside world, so that the part where the input pipe and the output pipe are connected can be cooled and dissipated by air with the outside world.

[0013] In the above technical solution, the technical effects and advantages provided by the present invention are: This product uses an evaporator to cool the incoming air in advance, allowing the air to precipitate moisture, and then the air is blown through the dehumidifying and drying particles by the fan so that the moisture is absorbed in advance, avoiding the problem of host control disorder caused by humid air in the existing technology; When the dehumidifying and drying particles absorb water, they will adhere to a certain amount of dust. Then, when the dehumidifying and drying particles are dried in the discharge pipe, the viscosity is reduced and the dust is blown out of the chassis directly, thereby reducing some of the dust entering the chassis, further reducing the possibility of host control disorder, and extending the cycle of thorough cleaning; This product uses the coordination between the spiral conveying device, the input pipe and the output pipe to make the dehumidifying and drying particles absorb moisture, then use the hot air discharged at the air outlet of the ventilation chamber to dry and remove moisture, and then return to the air inlet of the ventilation chamber to absorb moisture in the air and precipitated water, forming a cycle.
