Description

Technical Field

[0001] The present invention relates to the technical field of power distribution, and in particular to a three-phase high-power intelligent power distribution device. Background Art

[0002] PDU (Power Distribution Unit), also known as the cabinet power distribution socket, is a product designed to provide power distribution for cabinet-mounted electrical equipment. It can provide suitable rack-mounted power distribution solutions for different power supply environments.

[0003] Current smart PDU power distributors mostly use flexible wires soldered to connect the internal circuit boards and outlets. These wires have varying lengths and bends, creating a messy internal structure. Installing the power distributor in a cabinet or computer room takes up too much effective space, reducing the cabinet and room's volume ratio. The power consumption density is also low. Furthermore, most PDU products on the market lack efficient heat dissipation design and typically rely on their own heat conduction mechanism to gradually transfer internal heat to the outside air for heat dissipation. Because the busbar copper busbar requires a large number of connections, the wires, connectors, and contacts inside the PDU strips all have a certain resistance, causing the PDU strips to heat up, leading to excessively high ambient temperatures and poor heat dissipation. This situation not only affects the performance of the PDU equipment but also poses potential risks to its long-term stable operation. Therefore, improving the PDU's heat dissipation efficiency has become a pressing issue.

[0004] Therefore, we make improvements to this and propose a three-phase high-power intelligent power distribution device. Summary of the Invention

[0008] As a further solution of the present invention, the connecting plate is fixedly mounted on the top surface of the housing, and a plurality of arc-shaped air guide plates are connected to the bottom surface of the connecting plate.

[0009] As a further solution of the present invention, the universal fixing frame includes a gas collecting cavity, and a mounting plate is movably mounted on the back side of the gas collecting cavity.

[0010] As a further solution of the present invention, the mounting bracket includes a fixing plate, which spans the shell and the upper end of the universal fixing frame, and both ends of the fixing plate are fixedly connected to a hanging plate. A plurality of bayonet slots are provided in the middle of the fixing plate, and a card block is sleeved inside the bayonet slot. The card block is fixed to the universal fixing frame with bolts, and a push-pull plate is slidably sleeved on the upper end of the card block, and the front end of the push-pull plate is pressed on the top surface of the pluggable module.

[0011] As a further solution of the present invention, insulating baffles are installed at both ends of the interlayer between the universal fixing frame and the pluggable module.

[0014] The three-phase high-power intelligent power distribution device provided by the present invention has the following beneficial effects:

[0015] 1. By setting up space for storing multiple pluggable modules on one side of the shell and the universal fixing frame, and hingedly connecting the multiple pluggable modules to the universal fixing frame through hinges, the pluggable modules can be flipped along the hinge at the front end of the universal fixing frame. When flipping, the wiring part between the pluggable module and the busbar is exposed, which facilitates convenient and rapid maintenance of the wiring position of the busbar, increases the convenience of wiring and maintenance of the device, and does not need to open the rear buckle cover.

[0016] 2. By installing the busbar copper busbar in the interlayer space between the universal fixing frame and the pluggable module, and providing ventilation grid guards on both sides of the interlayer between the pluggable module and the universal fixing frame, the busbar copper busbar is separated from the internal components of the pluggable module. This not only facilitates the operation and processing of the wiring on the busbar copper busbar, but also allows independent ventilation and heat dissipation of the busbar copper busbar, thereby preventing a large amount of heat from accumulating on the busbar copper busbar and being unable to dissipate, affecting other components inside the pluggable module.

[0017] 3. By installing an air intake fan inside the universal fixing frame, connecting the pluggable module and the universal fixing frame through an air duct, installing a connecting plate and an air guide plate inside the pluggable module, the air flow inside the universal fixing frame is evenly blown out to the inside of the shell through the air duct and the air guide plate, and the inside of the shell is evenly dissipated. An exhaust fan is installed at the bottom of the shell, and the hot air inside the shell is blown out by the exhaust fan, so that the air inlet and outlet of the pluggable module are staggered to prevent the hot air from recirculating into the interior of the pluggable module, thereby facilitating the overall heat dissipation of the pluggable module.

[0030] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0031] like Figures 1-10 As shown, this embodiment proposes a three-phase high-power intelligent power distribution device, including a shell 1, a universal fixing frame 5 is fixedly connected to the rear end of the shell 1, and a plurality of independent pluggable modules 4 are provided at the front end of the universal fixing frame 5. Hinges 9 are installed on the upper ends of the shell 1 and the pluggable modules 4. Multiple pluggable modules 4 are installed side by side on one side of the shell 1, a main switch 2 and a junction box 3 are installed in the middle of the shell 1, a busbar copper bus 6 is connected to the middle of the shell 1, and the busbar copper bus 6 is fixedly installed on the front side of the universal fixing frame 5. The upper end of the universal fixing frame 5 is fixedly connected to a mounting bracket 7, and the front end of the mounting bracket 7 is squeezed on the upper end surface of the pluggable module 4. An air intake fan 8 is installed on the rear side of the universal fixing frame 5.

[0032] The pluggable module 4 includes a shell 41, a wire threading hole 46 is opened in the middle of the back of the shell 41, the inner pull-out connection of the shell 41 is connected to the plug-in frame 42, the rear end of the plug-in frame 42 is installed with a plug-in component 44, the plug-in component 44 is plugged and installed on the shell 41, and the plug-in component 44 penetrates the wire threading hole 46 and is connected to the busbar copper bus 6 wire. A connecting plate 43 is installed at the upper end of the inner part of the shell 41, and a bent plate 47 is connected to the rear end of the connecting plate 43. The outer end of the bent plate 47 is connected to the air duct 48, and the air duct 48 is fixedly connected to the universal fixing frame 5. An exhaust fan 45 is provided at the bottom end of the shell 41. The pluggable module 4 is a single pluggable power supply module as a whole. After the busbar copper bus 6 is connected to the wire of the plug-in component 44, it is hot-swapped with the plug-in frame 42, which is convenient for quick assembly and use of the device and can match sockets of different specifications.

[0033] The connecting plate 43 is fixedly mounted on the top surface of the outer shell 41, and a plurality of arc-shaped air guide plates 49 are connected to the bottom surface of the connecting plate 43. The air guide plates 49 are staggeredly mounted on the bottom surface of the connecting plate 43 in a fish-scale shape and bent downward. The gas passing through the air duct 48 is evenly dispersed and discharged into the interior of the outer shell 41 through the air guide plates 49, thereby evenly dissipating the heat inside the outer shell 41 and avoiding damage to the device due to insufficient heat dissipation in the blind area inside the outer shell 41.

[0034] The universal fixing frame 5 includes an air collecting chamber 51, and a mounting plate 52 is movably installed on the back of the air collecting chamber 51. An air intake fan 8 is installed inside the air collecting chamber 51 and the mounting plate 52. The air intake fan 8 introduces gas into the universal fixing frame 5 and enters the pluggable module 4 through the air duct 48 connected to the universal fixing frame 5 to dissipate heat for the pluggable module 4. The busbar copper busbar 6 is installed on the universal fixing frame 5 to fix the busbar copper busbar 6 while increasing the heat dissipation efficiency of the busbar copper busbar 6.

[0035] The mounting bracket 7 includes a fixing plate 71, which spans the shell 1 and the upper end of the universal fixing frame 5. Both ends of the fixing plate 71 are fixedly connected to a hanging plate 72. A plurality of bayonet holes 73 are provided in the middle of the fixing plate 71. A card block 74 is sleeved inside the bayonet hole 73. The card block 74 is bolted to the universal fixing frame 5. The upper end of the card block 74 is slidably sleeved with a push-pull plate 75. The front end of the push-pull plate 75 is pressed against the top surface of the pluggable module 4. The mounting bracket 7 is at the upper end of the universal fixing frame 5 to fix the shell 1 and the universal fixing frame 5 inside the container or other electrical equipment, and is fixed. The front end of the push-pull plate 75 slidably connected to the fixed plate 71 by the card block 74 is pressed against the pluggable module 4, preventing the pluggable module 4 from flipping upward and separating from the universal fixing frame 5, ensuring the stable connection between the pluggable module 4 and the universal fixing frame 5, and when the push-pull plate 75 is pushed backward, the push-pull plate 75 is separated from the pluggable module 4, the limit above the pluggable module 4 is cancelled, and the pluggable module 4 is flipped upward, and the interlayer space between the pluggable module 4 and the universal fixing frame 5 can be operated, making the wiring position behind each pluggable module 4 clearer and easier to operate.

[0036] Insulating baffles are installed at both ends of the interlayer between the universal fixing frame 5 and the pluggable module 4. Ventilation grids are provided on the insulating baffles, which can not only protect both ends of the interlayer between the pluggable module 4 and the universal fixing frame 5, but also prevent heat accumulation from being unable to be discharged, so that the busbar copper bar 6 can work stably and safely in the interlayer.

[0037] The air duct 48 is a soft insulating leather ventilation tube. As the shell 41 is flipped and deformed, the air duct 48 passes the gas in the universal fixing frame 5 into the pluggable module 4 to cool the pluggable module 4. The push-pull plate 75 pushes away from the top surface of the pluggable module 4, flips the pluggable module 4 upward, and repairs and inspects the wire part between the pluggable module 4 and the universal fixing frame 5. A circuit breaker and a leakage protector are installed on the pluggable module 4.

[0038] The jack 74 of the embodiment of the present invention is a kind of jack-in-the-box structure, and the jack 75 ... The busbar copper bar 6 is independently installed in the interlayer space between the universal fixing frame 5 and the pluggable module 4, which is convenient for processing the wiring on the busbar copper bar 6 and increasing the ventilation and heat dissipation effect of the busbar copper bar 6, thereby preventing a large amount of heat from accumulating on the busbar copper bar 6 and affecting other components inside the pluggable module 4; by installing an air intake fan 8 inside the universal fixing frame 5, and connecting the pluggable module 4 and the universal fixing frame 5 through an air duct 48, a connecting plate 43 and an air guide plate 49 are installed inside the pluggable module 4, and the air flow inside the universal fixing frame 5 is evenly blown out to the interior of the shell 41 through the air duct 48 and the air guide plate 49, so that the interior of the shell 41 is evenly dissipated. An exhaust fan 45 is installed at the bottom of the shell 41, and the hot air inside the shell 41 is blown out by the exhaust fan 45, so that the air inlet and outlet of the pluggable module 4 are staggered, thereby preventing the hot air from recirculating into the interior of the pluggable module 4, and facilitating the overall heat dissipation of the pluggable module 4. The content not described in detail in this specification belongs to the existing technology well known to professional and technical personnel in this field.
