Description
Technical Field

[0002] UPS (Uninterruptible Power System) is an uninterruptible power supply with energy storage device. It is mainly used to provide uninterruptible power supply to some equipment with high requirements on power supply stability. It is a system device that connects the battery to the host and converts DC power into AC power through module circuits such as the host inverter. During the operation of the UPS power supply, it is necessary to perform discharge maintenance regularly. During the discharge maintenance device, once a power outage occurs, the UPS power supply cannot provide power in time. Therefore, with the development of technology, at least two groups of power modules are set in the UPS power box to ensure that when one group of power is discharged and maintained, the other group of UPS power can be used as a substitute in time.
[0003] Nowadays, with the continuous advancement of UPS power technology, its internal structure is constantly changing, and the continuous use time is also increasing. However, the internal heat dissipation function is still an important factor affecting the service life of the power supply. Nowadays, the most widely used heat dissipation method is fan cooling. Although it can remove heat to a certain extent, it is large in size and occupies more space, which easily increases the volume of the entire UPS power box. Moreover, when the external temperature is high, it is difficult to achieve a rapid cooling effect by only using fan cooling. At the same time, when facing two sets of power modules, if both are equipped with a set of heat dissipation mechanisms, the power module in the non-operating state does not need heat dissipation, which is easy to cause a waste of resources;

Several specific embodiments are given below to introduce the technical solution of the present application in detail.
[0028] The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
[0029] like Figure 1-8As shown, it is a structural diagram of a UPS power supply with internal heat dissipation function provided by an embodiment of the present invention, comprising: a UPS power box 10, a battery module 11, a control compartment 13, and an independent battery 14; the battery module 11 is provided with two groups of intervals and distributed on both sides of the UPS power box 10, and the control compartment 13 is installed on the top of the UPS power box 10, and is used to control the operation of various components inside the UPS power box 10. By providing two groups of battery modules 11, it is ensured that the UPS power supply can provide continuous power supply, and the battery modules 11 on both sides are symmetrically isolated and distributed, and each group of battery modules 11 includes a plurality of groups of longitudinally detachable installations and distributed on The independent battery 14 inside the UPS power box 10 is provided with a control panel 16 at one end of the independent battery 14 facing the outside of the UPS power box 10. The control panel 16 is used to control the operation of each group of independent batteries 14. The UPS power box 10 corresponding to the independent battery 14 is provided with a mounting slot. The independent battery 14 is plugged into the mounting slot. The inner end of the mounting slot away from the opening of the UPS power box 10 is connected to an exhaust fan box 27. An exhaust fan 28 is provided inside the exhaust fan box 27. The driving shaft of the exhaust fan 28 movably passes through the exhaust fan box 27 and is externally connected to a rotating assembly. The rotating assembly is used to synchronously drive the exhaust fan 28 located at the same The exhaust fan 28 inside the battery module 11 on one side rotates, and then the exhaust fan 28 transports flowing gas toward the inside of the installation slot, so as to perform flow-type heat dissipation on the independent storage battery 14 installed in the installation slot. The lower side of the inlet end of the installation slot is connected to a gas transmission pipe 18, and the upper and lower gas transmission pipes 18 are connected to each other. The bottom end of the gas transmission pipe 18 located at the lowest point is connected to a gas return pipe 19 arranged inside the base 12. A refrigerator 43 for cooling the refluxed hot air is arranged in the middle of the gas return pipe 19. The end of the gas return pipe 19 is telescopically and movably connected to a cooling device 43 through a telescopic transmission gas pipe 20. The air delivery mechanism, the cold air delivery mechanism and the installation slot are plug-in connected, that is, a gas heat dissipation system for circulating the inside of the installation slot is formed, and then the exhaust fan 28 is set to further improve the cooling and heat dissipation effect of the independent battery 14 installed in the installation slot. The rotating component is plug-in connected to the cold air delivery mechanism, and a switching component is set on the side of the cold air delivery mechanism away from the middle of the UPS power box 10. The switching component is used to control the cold air transmission mechanism to adjust the position between the battery modules 11 on both sides, so as to facilitate real-time heat dissipation of the battery module 11 in operation, thereby ensuring effective and full utilization of resources.
[0030] In the embodiment of the present invention, a base 12 is fixedly installed at the bottom of the UPS power box 10 to maintain the stability of the UPS power box 10 when it is installed and positioned. When the independent battery 14 is installed in the installation groove, the control panel 16 is in sealing contact with the inlet end of the installation groove to maintain the sealing inside the installation groove. For the gas entering the heat dissipation, it is transferred to the gas return pipe 19 through the gas transmission pipe 18, and then cooled by the refrigerator 43, and then circulated again through the cold air delivery mechanism, that is, it is ensured that the gas is not affected by the external polluted gas during the process of alternating cold and hot conversion, and the protection of the independent battery 14 and other structures is guaranteed to a certain extent;
[0031] Since the switching component needs to control the cold air delivery mechanism to move between the battery modules 11 on both sides, the telescopic transmission air pipe 20 needs to move synchronously with the cold air delivery mechanism. At the same time, in order to ensure the smooth flow of gas in the gas return pipe 19, the output ends of the telescopic transmission air pipes 20 at the ends of the gas return pipes 19 on both sides are connected together, and are commonly connected with a sliding block 21. A sliding rail is provided on the side wall of the base 12 corresponding to the sliding block 21. The sliding block 21 moves laterally along the sliding rail. The outside of the sliding block 21 is connected with a cold air transmission telescopic channel 22. The cold air transmission telescopic channel 22 passes through the sliding block 21 and is connected to the telescopic air delivery pipe 20. The top of the cold air transmission telescopic channel 22 is connected to the cold air delivery mechanism, thereby ensuring that the cooling gas on both sides can be freely transmitted between the cold air delivery mechanism.
[0032] A plurality of slide bars 15 are evenly installed on the outer side wall of the independent storage battery 14, and a slide bar 15 is provided on the inner wall of the installation slot corresponding to the slide bar 15, and the slide bar 15 slides along the slide bar, thereby maintaining the independent storage battery 14 and the installation slot for quick and accurate installation and removal;
[0033] It should be noted that the specific connection structure and operation switching mode between the independent battery 14, the battery module 11, and the base 12 have been described in detail in the prior art, and will not be repeated here, but it does not affect the integrity of the present technical solution;

The bottom of the gas storage bin is connected to the connecting pipe, that is, under the connection of the cold air transmission telescopic channel 22 and the connecting pipe, the cold air inside the gas return pipe 19 is transferred to the cold air output pipe 25. A connecting hole 26 is opened on the mounting groove corresponding to the end of the cold air output pipe 25. The cold air output pipe 25 is connected to the connecting hole 26 by plugging, thereby transmitting the cold air to the outside of the independent battery 14 for heat dissipation.
[0035] For details, see Fig. 9 The inner side of the connecting hole 26 is set as a conical structure, and a circle of buffer plates 38 are set on the outer side of the conical structure. When the cold air output pipe 25 is inserted into the connecting hole 26, the buffer plate 38 is compressed by force, generating radial pressure on the cold air output pipe 25, thereby ensuring the sealed plug-in connection between the cold air output pipe 25 and the connecting hole 26.

The servo motor 31 is fixed to the cold air transmission plate 23 through a support rod, and the rotating rod 29 at the end of the cartridge 30 is driven to rotate by the plug-in connection between the clamping column 32 and the cartridge 30 and the rotation of the servo motor 31, and then the multiple exhaust fans 28 are driven to rotate synchronously under the connection of the transmission belt 41, so as to realize the function of a single motor synchronously driving multiple exhaust fans 28 to operate.

[0038] The switching assembly includes a U-shaped rod 24 installed on one side of the cold air transmission plate 23 on the upper and lower sides, a cylinder 44 is installed on the side of the middle part of the U-shaped rod 24 away from the center of the UPS power box 10, a nut 34 is connected to one side of the cylinder 44, a lead screw 35 is transversely threadedly connected to the middle part of the nut 34, one end of the lead screw 35 is connected to a servo motor 2 33, and a support sleeve rod 36 is sleeved on the other side, the servo motor 2 33 and the support sleeve rod 36 are fixed on the inner wall of the UPS power box 10, and a guide device for limiting its rotation is provided on the nut 34, the servo motor 2 33 is started to drive the lead screw 35 to rotate, and then the nut 34 is driven to move back and forth along the lead screw 35, and then under the connection of the cylinder 44, the position of the cold air transmission plate 23 is transferred, and then the cylinder 44 is cooperated to control the forward and backward movement of the cold air transmission plate 23 to realize the installation and removal of the clamping column 32 and the clamping cylinder 30.

Then, under the movement of the nut 34, the cylinder 44 is extended and retracted to connect the clamping column 32 with the corresponding clamping cylinder 30, and then the servo motor 1 31 is started to drive the exhaust fan 28 to rotate, thereby controlling the flow of cold air around the installation groove to cool the independent battery 14 in operation. The cold-cut gas is cooled along the gas transmission pipe 18 and the gas return pipe 19 through the refrigerator 43, and then flows back to the installation groove again through the cold air transmission telescopic channel 22, thereby controlling the gas to circulate and dissipate heat for the independent battery 14, and cooperates with the driving of the exhaust fan 28 to maintain the continuous flow of cold air.
