[0002] Three-phase UPS refers to an uninterruptible power supply whose input is three-phase AC mains. A three-phase UPS power supply is a device that can convert AC power into DC power and output it to the equipment to protect it from power fluctuations. The UPS in industry is a three-phase industrial frequency UPS.

[0003] However, the existing three-phase industrial frequency UPS will generate heat inside when working. Overheating may cause the equipment to freeze or crash. The natural heat dissipation effect is poor, resulting in slow heat dissipation. In addition, dust is easily accumulated at the heat dissipation position, making it inconvenient to disassemble and clean the heat dissipation position.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a three-phase industrial frequency UPS with good heat dissipation effect is provided. Utility Model Content

[0007] Furthermore, the holding frame and the heat dissipation fan are provided in four groups, and the holding frame and the top cover plate are vertically distributed, and the top cover plate and the dust cover are snap-fitted and connected.

[0008] Furthermore, a box door is installed at the front end of the box body through a rotating shaft, and a handle is arranged on the surface of the box door.

[0009] Furthermore, a fixing plate is installed on the side of the dust cover, and a controller is installed on the upper end of the box door.

[0010] Furthermore, an air outlet bottom box is installed at the bottom of the box body, and the air outlet bottom box is communicated with the interior of the box body.

[0011] Furthermore, a movable bottom plate is installed at the lower end of the air outlet bottom box, and a limiting component for increasing stability is arranged at the lower end of the movable bottom plate.

[0012] Furthermore, the limit assembly includes a limit box and an electric push rod, and the electric push rod is installed at the lower end of the limit box.

[0013] Furthermore, the limit assembly also includes a limit plate and a rubber sheet. The limit plate is installed at the output end of the electric push rod, and the rubber sheet is installed at the lower end of the limit plate.

[0014] The utility model provides a three-phase power frequency UPS with good heat dissipation effect, which has the following beneficial effects:

[0015] 1. The utility model communicates the dust cover with the inside of the box body, so that the box body can play a role of natural ventilation and heat dissipation when working, and at the same time, it plays a role of blocking external dust to prevent dust from entering the box body and causing influence. The cooling fan is installed on the mounting plate and inserted into the inside of the dust cover to promote the heat dissipation inside the box body, so that the heat dissipation effect inside the box body is good when working.

[0016] 2. The utility model uses an air outlet bottom box to displace the air inside the box and outside air when the cooling fan inside the box is working. The movable bottom plate makes it easy to change the position of the box according to usage requirements. The limit box is used for the hidden installation of the electric push rod. The electric push rod controls the movement of the limit plate by extending. When the box moves to the required position, the limit plate presses down on the ground under the action of the electric push rod, making the box unable to move while increasing its stability.

DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1 As shown, a three-phase industrial frequency UPS with good heat dissipation effect includes a box body 1 and an auxiliary component 4. Dust covers 3 are installed on both sides of the box body 1, and two groups of dust covers 3 are provided. The dust covers 3 are communicated with the inside of the box body 1, so that the box body 1 can play a role of natural ventilation and heat dissipation when working, and at the same time, it plays a role of blocking external dust to prevent dust from entering the inside of the box body 1 and causing influence. The top cover plate 401 and the dust cover 3 are snap-connected, and the front end of the box body 1 is equipped with a box door 2 through a rotating shaft, and the surface of the box door 2 is arranged on a handle 7. A fixing plate 5 is installed on the side of the dust cover 3, and a controller 6 is installed on the upper end of the box door 2. An air outlet bottom box 8 is installed at the bottom of the box body 1. The air outlet bottom box 8 enables the internal heat dissipation fan 404 of the box body 1 to replace the air inside the box body 1 with the outside air when working, and the air outlet bottom box 8 is communicated with the inside of the box body 1.

[0023] like Figure 2 As shown, an auxiliary component 4 for increasing the heat dissipation effect and facilitating cleaning and maintenance is arranged inside the dust cover 3, and the auxiliary component 4 includes a top cover plate 401, a holding frame 402, a mounting plate 403 and a heat dissipation fan 404. The holding frame 402 is installed on the upper end of the top cover plate 401, and the top cover plate 401 plays a role of sealing the top of the dust cover 3 for installation and removal. The holding frame 402 and the heat dissipation fan 404 are arranged in four groups, and the holding frame 402 and the top cover plate 401 are vertically distributed. The frame 402 connects the top cover plate 401, so that the cooling fans 404 on both sides can be synchronized, which is convenient for cleaning and replacement of the fan body and the dust cover 3, and increases the service life of the three-phase power frequency UPS. A mounting plate 403 is installed at the lower end of the top cover plate 401, and a cooling fan 404 is installed on the inner side of the mounting plate 403. The cooling fan 404 is installed on the mounting plate 403 and inserted into the inside of the dust cover 3, which promotes the heat dissipation inside the box body 1, so that the heat dissipation effect inside the box body 1 is good when working.

[0024] like Figure 3As shown, a movable bottom plate 9 is installed at the lower end of the air outlet bottom box 8, and the movable bottom plate 9 makes it easy for the box body 1 to change its position according to the use requirements, and a limit assembly 10 for increasing stability is arranged at the lower end of the movable bottom plate 9, and the limit assembly 10 includes a limit box 1001 and an electric push rod 1002, and the limit box 1001 is used for the hidden installation of the electric push rod 1002, and the lower end of the limit box 1001 is installed with the electric push rod 1002, and the electric push rod 1002 is The elongation controls the movement of the limit plate 1003. When the box 1 moves to the desired position, the limit assembly 10 also includes a limit plate 1003 and a rubber sheet 1004. The output end of the electric push rod 1002 is installed with the limit plate 1003. The limit plate 1003 is pressed down on the ground under the action of the electric push rod 1002, so that the box 1 cannot move while increasing its stability. The lower end of the limit plate 1003 is installed with a rubber sheet 1004, which increases the friction.

[0025] In summary, the three-phase power frequency UPS with good heat dissipation effect should first be based on Figure 1-Figure 3 In the structure shown in the figure, the three-phase power frequency UPS box 1 is bolted through the fixing plate 5 to install the dust cover 3 on both sides thereof, thereby increasing the natural ventilation area. The dust cover 3 is communicated with the inside of the box 1. At this time, the box 1 can play a role of natural ventilation and heat dissipation during operation, and at the same time, it plays a role of blocking external dust, thereby preventing dust from entering the inside of the box 1 and causing an impact. When natural heat dissipation cannot meet the heat dissipation requirements, the cooling fan 404 can be turned on to promote the heat dissipation inside the box 1, so that the heat dissipation effect of the three-phase power frequency UPS is good. When the cooling fan 404 is working, the air outlet bottom box 8 cooperates with the cooling fan 404 to promote the inside of the box 1 The dust cover 3 and the cooling fan 404 are replaced with external air to improve the cooling effect. When cleaning or replacing the dust cover 3 and the cooling fan 404, the mounting plates 403 on both sides can be lifted synchronously by the holding frame 402 for cleaning the cooling fan 404. The dust cover 3 can be cleaned or replaced by removing the fixing plate 5. When installing a three-phase industrial frequency UPS, after moving the bottom plate 9 to the desired position, the electric push rod 1002 is controlled to extend so that the limit plate 1003 contacts and presses down the ground (without lifting the moving bottom plate 9), so that the box body 1 cannot move while increasing its stability, and the rubber sheet 1004 increases the friction.
