[0002] A UPS (Uninterruptible Power Supply) is a device that provides temporary power support when the mains power is abnormal. It is mainly used to ensure the continuous operation of equipment with high power stability requirements. It supplies the load with the mains power after stabilizing it through a rectifier, while regulating voltage fluctuations to prevent equipment from being damaged due to voltage instability. It also filters out abnormal signals such as noise and frequency instability in the mains power, protects the equipment from power interference, and ensures the uninterrupted operation of critical services such as servers and network equipment.

Therefore, they do not meet current needs. To address this, we propose a rack-mounted UPS uninterruptible power supply. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model integrates an uninterruptible power supply unit inside a sealed box, so that the voltage regulator box and the backup battery are fixedly connected to the sealed box. The sealed box is then placed inside a protective shell. A locking knob passes through the protective shell and locks the positioning block. The protective shell, through four positioning blocks and the locking knob, helps to maintain the stability of the sealed box.

A power connection plate 203 is fixedly installed on the inner side of the front end of the sealed box body 201. Multiple power connection ports are provided on both sides of the movable power connection roller 102 and the front end face of the power connection plate 203. The movable power connection roller 102 and the power connection plate 203 are connected by a cable. A support base 204 is fixedly installed at the bottom end of the sealed box body 201. An insulating partition 205 is fixedly installed in the middle of the upper end face of the support base 204. Positioning grooves 202 are provided at the four corners of the upper end face of the sealed box body 201. The bottom end of the positioning groove 202 is in contact with the inner wall of the protective shell 101. The positioning block 104 is inserted into the inner side of the positioning groove 202. The sealed power connection mechanism 2 can provide sealed protection for the uninterruptible power supply unit.
[0017] Please see Figure 4 The uninterruptible power supply unit includes a voltage regulator box 301, a backup battery 302 installed at the rear of the voltage regulator box 301, and a power connection plate 303 installed between the voltage regulator box 301 and the backup battery 302. The two ends of the power connection plate 303 pass through the insulating partition 205 and are fixedly connected to the voltage regulator box 301 and the backup battery 302. The voltage regulator box 301 is equipped with an inverter, a rectifier, an air switch, an electronic ammeter and an electronic voltmeter. The inverter, rectifier, air switch, electronic ammeter and electronic voltmeter are all electrically connected to the backup battery 302. The voltage regulator box 301 can regulate the input current and output it. Both the upper and lower ends of the voltage regulator box 301 and the backup battery 302 are equipped with heat dissipation fin brackets 305. A heat conduction box 304 is fixedly installed between two adjacent heat dissipation fin brackets 305. The two heat conduction boxes 304 are symmetrically installed relative to the insulating partition 205 and are fixedly connected to the insulating partition 205. The heat conduction box 304 contains a heat conduction medium. The two ends of the two heat conduction boxes 304 are connected to the voltage regulator box 301 and the backup battery 302 through the heat dissipation fin brackets 305. The two ends of the voltage regulator box 301 and the backup battery 302 are in close contact with the four heat dissipation fin brackets 305. The heat dissipation fin brackets 305 can continuously dissipate heat from the voltage regulator box 301 and the backup battery 302.
[0018] In summary, when using a rack-mounted UPS power supply, the uninterruptible power supply unit is built into the inside of the sealed box 201, so that the voltage regulator box 301 and the backup battery 302 are fixedly connected to the sealed box 201. Then, the sealed box 201 is placed inside the protective housing 101. At this time, the positioning block 104 is inserted into the inside of the positioning groove 202. The locking knob 105 is rotated so that the locking knob 105 passes through the protective housing 101 and locks the positioning block 104. Thus, the protective housing 101 can easily maintain the installation stability of the sealed box 201 through the four positioning blocks 104 and the locking knob 105. Multiple power connection ports are provided on both sides of the movable power connection roller 102 and the front end of the power connection plate 203. Thus, the movable power connection roller 102 and the power connection plate 203 can transmit external current to the inside of the voltage regulator box 301 through the power connection ports. The voltage regulator box 301 houses an inverter, rectifier, air switch, electronic ammeter, and electronic voltmeter. The voltage regulator box 301 regulates the input current and outputs it. Simultaneously, the power connection plate 303 facilitates continuous charging of the backup battery 302. When the external power is interrupted, the backup battery 302 supplies power to the voltage regulator box 301 in reverse through the power connection plate 303, maintaining uninterrupted power output. A temperature difference exists between the voltage regulator box 301 and the backup battery 302 during operation. The heat transfer medium inside the heat-conducting box 304 flows within the adjacent heat dissipation fin frame 305 due to this temperature difference, continuously cooling the voltage regulator box 301 and the backup battery 302, thus improving temperature stability during uninterrupted UPS power supply.
