Abstract
Description
Technical Field
[0001] This utility model relates to the field of power equipment technology, specifically to a power distribution cabinet for power systems that facilitates heat dissipation. Background Technology
[0002] A distribution cabinet is an integrated electrical device used for power distribution, control, and protection. It controls the on / off state of circuits through components such as circuit breakers and disconnect switches, and also has overload and short-circuit protection functions to ensure system safety. Therefore, the distribution cabinet is a core electrical device in the process of building a power system.
[0003] Existing power distribution cabinets are centrally located and installed in the computer room for convenient centralized control. However, due to the high integration of electrical equipment inside the cabinets, they easily generate heat during use. Therefore, the power distribution cabinets need to have heat dissipation capabilities. Existing power distribution cabinets have separate heat dissipation mechanisms and ventilation holes at the top and bottom. This not only makes it easy for dust to enter the interior of the power distribution cabinet through the ventilation holes at the top, but also increases the manufacturing and power costs of the power distribution cabinet. Furthermore, during the heat dissipation process, the generated heat cannot be dissipated outside the computer room, causing the computer room temperature to increase and reducing the overall heat dissipation and cooling effect. Utility Model Content
[0004] The purpose of this utility model is to solve the problems mentioned above, such as dust easily entering the interior of the power distribution cabinet through the heat dissipation holes at the top, increasing the manufacturing and power consumption costs of the power distribution cabinet, and the inability to dissipate the generated heat outside the computer room during the heat dissipation process, which increases the temperature of the computer room and reduces the overall heat dissipation and cooling effect. This utility model provides a power distribution cabinet for power systems that facilitates heat dissipation.
[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: A power distribution cabinet for easy heat dissipation in a power system includes a cabinet body arranged horizontally. A cold air frame is provided inside the bottom of the cabinet body, and an air intake hood is fixedly installed at the front end of the cold air frame. A hot air frame is provided inside the top of the cabinet body. Ventilation slots are provided in the partition between the cold air frame and the hot air frame inside the cabinet body. A connecting pipe is fixedly installed at the rear end of the top of the cabinet body. Fixing rods are fixedly installed at the top of the leftmost and rightmost ends of the cabinet body. A blower pipe is fixedly installed on the rear side of the fixing rod. A blower assembly is provided on the left side of the blower pipe.
[0006] Furthermore, an exhaust vent is provided at the rear end of the top of the cabinet, and the exhaust vent is located at the connection between the connecting pipe and the hot air frame, so that the exhaust vent can obstruct foreign objects while the hot air inside the hot air frame can be discharged to the outside through the exhaust vent and the connecting pipe.
[0007] Furthermore, the ventilation slot extends vertically through the hot air frame and the cold air frame, allowing the cold air at the bottom to flow upwards inside the cabinet.
[0008] Furthermore, the rear ends of the connecting pipes are all fixedly installed with the blower pipes, and the connecting pipes and the blower pipes are interconnected. Therefore, when air flows inside the blower pipes, hot air inside the hot air frame can be drawn in through the connecting pipes.
[0009] Furthermore, the blower duct is made of a high thermal conductivity metal material, and the connection area between the middle of the blower duct and the connecting pipe is designed with a threaded tube. The threaded tube increases the heat dissipation area, and thus the heat dissipation effect at the connecting pipe can be improved even when the blower duct is not blowing air.
[0010] Furthermore, the blower assembly includes a conical cylinder, the left end of the blower pipe is fixedly connected to the conical cylinder, a mounting frame is fixedly installed inside the conical cylinder, a motor is fixedly installed on the inner side of the center of the mounting frame, a fan blade is driven to the right side of the motor, and a protective net is fixedly installed on the inner side of the left opening of the conical cylinder. Therefore, by driving the rotation of the fan blade by the motor, air can be blown to the right inside the blower pipe.
[0011] Furthermore, a bend is fixedly inserted into the right side of the blower pipe, and the bend is bent backward, so that heat can be discharged outside the machine room by extending the bend backward to the outside of the machine room.
[0012] The beneficial effects of this utility model are as follows: This invention utilizes a design that installs air ducts on the rear side of cabinets arranged in a computer room. By connecting the air ducts to the rear top of the cabinets and working in conjunction with the air duct assembly, the cabinets can be centrally cooled. This avoids the need for separate cooling mechanisms for each power distribution cabinet, prevents dust from entering, and reduces the manufacturing and power costs of the power distribution cabinets. Furthermore, the air duct design allows for easy removal of heat from the computer room by installing bends, preventing the room temperature from increasing and improving the heat dissipation effect.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0016] A preferred embodiment of the present invention provides a power system distribution cabinet with convenient heat dissipation, which will be described in detail below. Figures 1-7 As shown, a power distribution cabinet for easy heat dissipation in a power system includes a cabinet body 1, which is arranged horizontally. A cold air frame 2 is provided inside the bottom of the cabinet body 1, and an air inlet hood 3 is fixedly installed at the front end of the cold air frame 2. A hot air frame 4 is provided inside the top of the cabinet body 1. Ventilation slots 5 are provided in the partition between the cold air frame 2 and the hot air frame 4 inside the cabinet body 1. The ventilation slots 5 pass through the hot air frame 4 and the cold air frame 2 vertically, so that the cold air at the bottom can flow from bottom to top inside the cabinet body 1. A connecting pipe 6 is fixedly installed at the rear end of the top of the cabinet body 1. An exhaust slot 41 is provided at the rear end of the top of the cabinet body 1, and the exhaust slot 41 is located at the connection between the connecting pipe 6 and the hot air frame 4. This allows the exhaust slot 41 to obstruct foreign objects while the hot air inside the hot air frame 4 can be discharged to the outside through the exhaust slot 41 and the connecting pipe 6.
[0017] A fixing rod 7 is fixedly installed on the top of the left end of the leftmost cabinet 1 and the top of the right end of the rightmost cabinet 1. A blower pipe 8 is fixedly installed on the rear side of the fixing rod 7. The rear end of the connecting pipe 6 is fixedly installed with the blower pipe 8, and the connecting pipe 6 and the blower pipe 8 are connected to each other. Therefore, when air flows inside the blower pipe 8, the hot air inside the hot air frame 4 can be drawn in through the connecting pipe 6.
[0018] The blower pipe 8 is made of a high thermal conductivity metal material, and the connection area between the middle of the blower pipe 8 and the connecting pipe 6 is designed with a threaded pipe 81. The threaded pipe 81 increases the heat dissipation area, and thus the heat dissipation effect at the connecting pipe 6 can be improved even when the blower pipe 8 is not blowing air.
[0019] A bend 10 is fixedly inserted into the right side of the blower duct 8, and the bend 10 is bent backward, so that heat can be discharged outside the machine room by extending the bend 10 backward to the outside of the machine room.
[0020] A blower assembly 9 is provided on the left side of the blower pipe 8. The blower assembly 9 includes a conical cylinder 91. The left end of the blower pipe 8 is fixedly connected to the conical cylinder 91. A mounting bracket 92 is fixedly installed inside the conical cylinder 91. A motor 93 is fixedly installed on the inner side of the center of the mounting bracket 92. A fan blade 94 is driven to the right side of the motor 93. A protective net 95 is fixedly installed on the inner side of the opening on the left side of the conical cylinder 91. Therefore, by driving the rotation of the fan blade 94 through the motor 93, air can be blown to the right inside the blower pipe 8.
[0021] The working principle of this utility model is as follows: During installation, the cabinet 1 is arranged in a left-right arrangement. After the internal electrical equipment is installed and connected, the blower pipe 8 is installed on the rear side of the top of the cabinet 1 through the fixing rod 7. The front side of the blower pipe 8 is connected to the connecting pipe 6 at the rear end of the top of the cabinet 1. Then, the blower assembly 9 is installed on the left side of the blower pipe 8, and the elbow 10 is fixedly inserted on the right side of the blower pipe 8. The elbow 10 is extended backward to the outside of the machine room.
[0022] When the cabinet 1 is operating normally, the heat generated can flow upward in the air and then enter the hot air frame 4. With the use of a high thermal conductivity metal material for the blower pipe 8 and the design of the central threaded pipe 81, as well as the function of the exhaust groove 41 and the connecting pipe 6, the heat can enter the blower pipe 8 through the exhaust groove 41 and the connecting pipe 6 for heat dissipation and cooling.
[0023] When the inside of cabinet 1 overheats, the motor 93 inside the conical cylinder 91 is activated, causing the motor 93 to drive the fan blades 94 to rotate. Under the action of the rotating fan blades 94, air can be blown to the right inside the blower pipe 8. Under the action of air flow, the hot air flowing upward into the hot air frame 4 can be drawn through the connecting pipe 6 and the exhaust groove 41, and the hot air can be blown out of the computer room through the blower pipe 8 and the bend pipe 10, so as to avoid overheating inside the computer room and ensure the heat dissipation effect.
[0024] During the process of drawing hot air from the hot air frame 4, the hot air frame 4 and the cold air frame 2 are connected vertically by the ventilation groove 5. Under the action of negative pressure, the cold air at the bottom can enter the cold air frame 2 through the air inlet hood 3 and flow upward inside the cabinet 1 through the ventilation groove 5. This, combined with the exhaust of hot air, achieves the heat dissipation and cooling effect.
[0025] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
