Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and more particularly to a power distribution cabinet for outdoor energy-saving and heat dissipation. Background Art

[0002] The power distribution cabinet is a general term for the motor control center. Because it contains a large number of electrical equipment, it will generate a lot of heat when powered on for a long time, which will accelerate the aging of the equipment and may even cause circuit short circuit failures. Therefore, it is very important to solve the heat dissipation problem of the power distribution cabinet.

[0003] At present, ordinary power distribution cabinets on the market only solve the heat dissipation problem by opening a few heat dissipation holes. This method has poor heat dissipation performance and cannot completely solve the heat dissipation problem.

[0004] The heat dissipation type distribution cabinet in the prior art includes components such as an electrical box, a mounting frame, a first hinged frame, an opening and closing frame and a first gear. When in use, the electrical equipment can be installed in the electrical box through the mounting frame and the mounting hole. The opening and closing frame can be closed or opened by the first hinged frame in conjunction with the card slot and the card rod. The first opening and closing leaf and the second opening and closing leaf cooperate with the heat dissipation hole to allow air to circulate in the electrical box so that the heat can be dissipated. The motor and the blowing fan blades can draw the heat in the electrical box away with the air to achieve the effect of sufficient heat dissipation. However, the device often consumes a lot of electricity when in use, and the heat dissipation quality is poor, and it cannot effectively dissipate the heat of the distribution cabinet.

[0005] Therefore, how to provide a power distribution cabinet for outdoor energy-saving and heat dissipation that can effectively dissipate heat from the power distribution cabinet and save electricity is a problem that technical personnel in this field urgently need to solve.

[0026] The cabinet 1 has a bottom box 2 at the bottom, a top box 3 at the top, and a winding tube 4 on the side wall of the cabinet 1. The bottom box 2 is connected to the top box 3 through the winding tube 4. In the present embodiment, antifreeze is provided in both the bottom box 2 and the top box 3. The top box 3 is provided at the top of the cabinet 1, and the bottom box 2 is provided at the bottom of the cabinet 1. A left vertical box is vertically provided on the bottom box 2, and the left vertical box is connected to the bottom box 2. A right vertical box is provided on the top box 3. The left vertical box is provided at the front end of the left side board of the cabinet 1, and the right vertical box is provided at the front end of the right side of the cabinet 1. One end of some winding tubes 4 is connected to the left vertical box, and the other end bypasses the rear side of the cabinet 1 and is connected to the right vertical box. When in use, the antifreeze can flow from the left vertical box and the bottom box 2 to the right box and the top box 3, so as to exchange heat with the outer wall of the cabinet 1, so as to shorten the speed of the liquid flowing through the outer wall of the cabinet 1 when in use, so as to better cool the outer wall of the cabinet 1.

[0027] An outer box 5 is sleeved on the top, bottom, left side wall and right side wall of the cabinet body 1. The outer box 5 is sealed and connected to the cabinet body 1. There is a gap between the outer box 5 and the cabinet body 1, and the gap is a guide cavity 6. An air inlet hole 7 is provided at the bottom of the outer box 5, and an air outlet hole is provided at the top of the outer box 5. The guide cavity 6 is connected with the atmosphere below the outer box 5 through the air inlet hole 7, and the guide cavity 6 is connected with the atmosphere above the outer box 5 through the air outlet hole; the outer box 5 includes a top plate, a bottom plate, a left side plate, a right side plate and a rear side plate. The rear side plate is arranged on the back of the cabinet body 1, and the left side plate and the right side plate are respectively arranged on the left and right sides of the cabinet body 1. One end of the left side plate and the right side plate are respectively fixedly connected to the rear side plate, and a connecting plate 8 is provided on the side of the left side plate and the right side plate away from the rear side plate. The connecting plate 8 is connected to the cabinet body 1, and the top plate is provided It is placed on the top of the cabinet 1, and the top plate is rectangular. One end of the top plate is fixedly connected to the rear side plate, and the other end of the top plate is connected to the top of the cabinet 1 through a connecting plate 8. One end of the bottom plate is fixedly connected to the rear side plate, and the two sides of the bottom plate are connected to the left side plate and the right side plate. There are gaps between the top plate, the bottom plate, the left side plate, the right side plate and the top plate and the cabinet 1, which are guide chambers 6. The side of the bottom plate and the bottom of the cabinet 1 away from the rear side plate is an air inlet 7. In this embodiment, the guide chambers 6 are distributed on the left, right, rear, top and bottom sides of the cabinet 1. By setting the guide chamber 6, a chimney 9 effect can be formed on the left, right, rear, bottom and top sides of the cabinet 1. Natural ventilation under the action of heat pressure, due to the temperature difference between the air inside and outside the outer box 5, a difference in air density is generated, thereby forming a pressure difference, driving the flow of air inside and outside the guide chamber 6. The air with high temperature in the guide chamber 6 rises due to its low specific gravity and is discharged from the guide chamber 6 from the air outlet at the top of the outer box 5. At this time, a negative pressure area will be formed in the low-density air guide chamber 6, so the fresh air with relatively low temperature and high specific gravity outside the outer box 5 is sucked in from the bottom air inlet 7 of the guide chamber 6, and the indoor and outdoor air flows continuously in the guide chamber 6, and the cold air enters the guide chamber 6 from the air inlet 7, and the hot air after heat exchange flows into the atmosphere from the air outlet at the top of the guide chamber 6.

[0029] An internal fan 16 is arranged on the side wall of the bottom box 2, and the other end of the internal fan 16 is fixedly connected to the side wall of the outer box 5. The internal fan 16 supplies air from bottom to top, and multiple internal fans 16 are arranged; in the present embodiment, the internal fan 16 is arranged in the guide cavity 6, and multiple fans can increase the air flow rate, thereby increasing the heat exchange efficiency of the multiple guide cavities 6. When in use, the antifreeze can also be heat exchanged, and the heat in the antifreeze is transferred to the cold air and discharged from the top air outlet of the guide cavity 6.
