Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and more specifically to an intelligent power distribution cabinet. Background Technology

[0002] A distribution cabinet is used to distribute the total electrical energy obtained from the transformer or incoming cable to various branch circuits according to design requirements, ensuring that every piece of equipment (such as lighting, air conditioning, and production machinery) in the factory or building receives the necessary power. Through integrated switches, circuit breakers, and other components, it can easily connect or disconnect circuits. When an overload, short circuit, or leakage occurs, it can automatically cut off the power supply, protecting personnel and equipment safety. Distribution cabinets are typically equipped with voltmeters, ammeters, and energy meters to monitor the circuit's operating status and measure power consumption in real time.

[0003] In existing technology, electrical components in a distribution cabinet generate heat during operation. To dissipate heat and cool these components, an exhaust fan is directly installed on the cabinet's casing. This fan draws hot air out of the cabinet and allows cooler outside air to flow in, thus cooling the electrical components. However, a large amount of dust from the air also enters the cabinet, and this dust adhering to the electrical components can potentially cause short circuits. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent power distribution cabinet that can prevent dust mixed in with the outside air from adhering to electrical components.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A smart power distribution cabinet includes a housing. A frame is fixedly connected to the back panel of the housing cavity. The frame has several forward-extending longitudinal beams that collectively support a coolant tank. A mounting frame is fixedly connected to the front end of each longitudinal beam. A mounting plate is fixedly connected to the mounting frame. Electrical components are mounted on the front side of the mounting plate. An insulating mounting base is fixedly connected to the front wall of the coolant tank. Several heat-conducting blocks are mounted on the insulating mounting base. A heat-conducting plate is fixedly connected to the front side of each heat-conducting block and to the rear side of the mounting plate. Each heat-conducting block is perforated with a liquid storage pipe, which is vertically arranged. Adjacent heat-conducting blocks are connected in series. The liquid pipes are connected end to end to form a whole. The top of the shell is equipped with a heat dissipation chamber, and a heat dissipation coil is installed inside the heat dissipation chamber. An opening is provided on the top side of the heat dissipation chamber, and a heat dissipation exhaust fan is installed at the opening. The outlet of the end liquid storage pipe is connected to the inlet of the heat dissipation coil through a pipe. The outlet of the heat dissipation coil is connected to the return port of the coolant tank through a pipe. A liquid flow pump is installed on the front wall of the coolant tank. The outlet of the coolant tank is connected to the inlet of the liquid flow pump through a pipe. The outlet of the liquid flow pump is connected to the inlet of the other end liquid storage pipe through a pipe.

[0006] Specifically, four heat-conducting plates are fixed to the rear side of the mounting plate. The four heat-conducting plates are arranged horizontally, and the four corners of the heat-conducting plates are fixed to the mounting plate by screws.

[0007] Specifically, a temperature sensor is installed at the bottom of the liquid storage tube.

[0008] Specifically, the liquid storage tube is made of glass or transparent plastic.

[0009] Specifically, the heat dissipation coil is formed by the meandering and bending of the pipes, and the heat dissipation coil is set horizontally. The side wall of the heat dissipation chamber is provided with air inlet holes.

[0010] Specifically, a protective cover is provided outside the heat dissipation chamber, and a ventilation gap is left between the protective cover and the outer wall of the heat dissipation chamber. An air inlet is provided on the rear side of the protective cover.

[0011] Specifically, the shell has side plates on both sides of its lateral direction, and the side plates have ventilation holes.

[0012] Specifically, the coolant tank has an opening, and the opening is fitted with a cap. Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses a heat-conducting plate to transfer the heat from the mounting plate to the liquid storage pipe. Once the coolant in the storage pipe reaches a preset temperature, it circulates under the drive of a liquid pump. As a liquid medium, the coolant has better thermal conductivity than air. Furthermore, using coolant for heat absorption avoids the problems associated with directly using outside air for heat dissipation—dust particles in the outside air can adhere to electrical components, posing a risk of short circuits.

[0013] After the coolant in the reservoir absorbs heat and rises to a preset temperature, it will be pumped into the heat sink coil (not shown in the figure). At this time, the cooling fan drives the air to circulate in the heat sink chamber, cooling the heat sink coil (not shown in the figure). During this process, dust in the air will only adhere to the heat sink coil (not shown in the figure) and will not affect the electrical components. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] See Figures 1 to 3 An intelligent power distribution cabinet includes a housing, with a frame fixedly connected to the back panel of the housing cavity. The frame has several forward-extending longitudinal beams 11, which together support a coolant tank 12. A mounting frame 13 is fixedly connected to the front end of each longitudinal beam 11, and a mounting plate 14 is fixedly connected to the mounting frame 13. Electrical components are mounted on the front side of the mounting plate 14.

[0019] See Figure 3 , Figure 4 A heat-insulating mounting base 21 is fixed to the front wall of the coolant tank 12. Several heat-conducting blocks 22 are mounted on the heat-conducting mounting base 21. A heat-conducting plate 23 is fixed to the front side of each heat-conducting block 22, and the heat-conducting plate 23 is fixed to the rear side of the mounting plate 14. Each heat-conducting block 22 is fitted with a liquid storage pipe 24. The liquid storage pipes 24 are arranged vertically, and adjacent liquid storage pipes 24 are connected end-to-end to form a single unit (see...). Figure 4 ).

[0020] See Figure 3 , Figure 4 The top of the casing is provided with a heat dissipation chamber 31, and a heat dissipation coil (not shown in the figure) is installed inside the heat dissipation chamber 31. An opening is provided on the top side of the heat dissipation chamber 31, and a heat dissipation exhaust fan 32 is installed at the opening. The end liquid storage pipe 24 (located at...) Figure 3 The outlet of the coolant tank 12 (located on the right side) is connected to the inlet of the radiator coil (not shown) via pipe A. The outlet of the radiator coil (not shown) is connected to the return port of the coolant tank 12 via pipe B. A liquid flow pump 4 is installed on the front wall of the coolant tank 12. The outlet of the coolant tank 12 is connected to the inlet of the liquid flow pump 4 via pipe C. The outlet of the liquid flow pump 4 is connected to the other end of the reservoir pipe 24 (located on the right side) via pipe D. Figure 3 The inlet on the left side of the middle is connected.

[0021] Specifically, see Figure 4 Four heat-conducting plates 23 are fixedly attached to the rear side of the mounting plate 14. The four heat-conducting plates 23 are arranged in a horizontal direction, and the four corners of the heat-conducting plates 23 are fixedly attached to the mounting plate 14 by screws.

[0022] Specifically, see Figure 4 A temperature sensor 241 is provided at the bottom of the liquid storage tube 24.

[0023] Specifically, see Figure 4 The liquid storage tube 24 is made of glass or transparent plastic.

[0024] Specifically, refer to Figure 3 The heat dissipation coil (not shown in the figure) is formed by the meandering and bending of the pipes. The heat dissipation coil is set horizontally, and the side wall of the heat dissipation chamber 31 is provided with air inlet holes.

[0025] Specifically, a protective cover 33 is provided outside the heat dissipation chamber 31, and a ventilation gap is left between the protective cover 33 and the outer wall of the heat dissipation chamber 31. An air inlet is provided on the rear side of the protective cover 33.

[0026] Specifically, the shell has side plates on both sides of its lateral direction, and the side plates have ventilation holes.

[0027] Specifically, the coolant tank 12 has an opening, and the opening is provided with a cap 15.

[0028] The working principle of this invention is as follows: Electrical components are mounted on the front side of the mounting plate 14. During operation, these components generate heat. A heat-conducting plate 23 is fixedly connected to the rear side of the mounting plate 14, and a heat-conducting block 22 is fixedly attached to the heat-conducting plate 23. When the electrical components generate heat, the mounting plate 14 also heats up. The contact area between the heat-conducting plate 23 and the mounting plate 14 is large enough to absorb the heat generated by the mounting plate 14 and transfer it to the liquid storage pipe 24 through the heat-conducting block 22.

[0029] The reservoir pipe 24 is filled with coolant. A temperature sensor 241 is installed at the bottom of the reservoir pipe 24. When the temperature sensor 241 senses that the liquid temperature in the reservoir pipe 24 is higher than a preset value, the temperature sensor 241 feeds back to the controller, causing the flow pump 4 to start. The flow pump 4 pumps the relatively cooler coolant from the coolant tank 12 to the end reservoir pipe 24 (located at the end of the reservoir pipe 24). Figure 3 (Left side of the middle) Because the two adjacent liquid storage pipes 24 are connected end to end, the coolant whose temperature rises in the liquid storage pipe 24 flows through the other end of the liquid storage pipe 24 (located in the middle left). Figure 3 The liquid flows from the outlet on the right side of the middle section to the inlet of the heat dissipation coil (not shown in the figure) inside the heat dissipation chamber 31, and then flows from the outlet of the heat dissipation coil (not shown in the figure) into the coolant tank 12.

[0030] As the cooled liquid, whose temperature has risen, flows through the radiator coil (not shown), the cooling fan 32 draws air out, thereby exchanging heat with the radiator coil (not shown) through the outside air. This rapidly cools the coolant flowing through the radiator coil (not shown) and then it flows into the coolant tank 12 for later use. In this way, the coolant in the coolant tank 12 is always kept at a low temperature, which can be used to cool the mounting plate 14 at any time.

[0031] The beneficial effects of this invention are as follows: This invention uses a heat-conducting plate 23 to transfer the heat from the mounting plate 14 to the liquid storage pipe 24. When the coolant in the liquid storage pipe 24 reaches a preset temperature, the coolant circulates under the drive of the liquid flow pump 4. The coolant is a liquid medium, and its thermal conductivity is better than that of air. In addition, using coolant to absorb heat avoids the problems caused by directly using outside air for heat dissipation—dust mixed in with outside air adheres to electrical components, posing a risk of short circuit.

[0032] After the coolant in the reservoir 24 absorbs heat and rises to a preset value, it will be pumped into the heat sink coil (not shown in the figure). At this time, the cooling fan 32 drives the air to flow in the heat sink 31 to cool the heat sink coil (not shown in the figure). During this process, the dust in the air will only adhere to the heat sink coil (not shown in the figure) and will not affect the electrical components.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
