Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a power distribution cabinet with good heat dissipation performance. Background Technology

[0002] Distribution cabinets are an important component of power systems, and their heat dissipation performance directly affects the stability and service life of the equipment. Electronic components and electrical equipment in the control cabinet generate a lot of heat during operation. If the heat is not properly controlled, it will seriously affect the performance and service life of the equipment. Excessive temperature can lead to problems such as failure of electronic components, deterioration of electrical insulation performance, and wear of mechanical parts. In addition, high temperature environment will also accelerate the aging of equipment and shorten its service life.

[0003] In actual use, the existing power distribution cabinets have been found to have the following shortcomings:

[0004] The internal layout of the distribution cabinet is problematic. The electrical components are installed too densely at the rear of the cabinet, making it difficult for air to circulate between the components. This causes localized heat buildup, hinders airflow, and results in poor heat dissipation in the distribution cabinet.

[0005] Therefore, this application provides a power distribution cabinet with good heat dissipation performance to meet the requirements. Utility Model Content

[0006] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a power distribution cabinet with good heat dissipation performance.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A power distribution cabinet with good heat dissipation performance includes: a cabinet body, a cabinet door, a mounting rack, a surface-mount temperature sensor, a fan, a frame, a rotating shaft, a guide plate, heat dissipation fins, and an exhaust fan. The top of the cabinet body has a ventilation chamber, the bottom of the cabinet body has an exhaust chamber, the front of the cabinet body has a cabinet door, the rear interior of the cabinet body has a mounting rack, the side of the mounting rack has a surface-mount temperature sensor, the ventilation chamber has a fan, the exhaust chamber has an exhaust fan, the back of the cabinet door has a frame, the inner side of the frame has a guide plate mounted via a rotating shaft, and the surface of the guide plate has heat dissipation fins.

[0009] Preferably, the ventilator is connected to the vent at the top of the ventilation chamber, the lower end of the ventilation chamber is provided with an air outlet, and the air outlet of the ventilator is directly opposite the air outlet of the ventilation chamber.

[0010] Preferably, the back of the cabinet door is provided with three sets of frames, rotating shafts and guide plates, and the three sets of frames, rotating shafts and guide plates are distributed at equal intervals.

[0011] Preferably, the frame is installed on the left and right sides of the door frame on the back of the cabinet door. The frame is rectangular and horizontally arranged, with the other end of the frame extending to the lower end of the air outlet of the ventilation chamber.

[0012] Preferably, the guide plate is installed on the inner side of the two sets of racks, and the guide plate is located at the other end of the rack away from the cabinet door.

[0013] Preferably, the guide plate is movably connected to the frame via a rotating shaft, and the rotating shaft is equipped with a rotating shaft locking structure.

[0014] Preferably, the guide plate is rectangular, and several sets of heat dissipation fins are horizontally mounted on the surface of the guide plate.

[0015] Preferably, the heat dissipation fins are rectangular strips, and there are gaps between the heat dissipation fins.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above solution, three sets of racks, shafts, and deflectors are installed on the back of the cabinet door. When the cabinet door is closed, the racks and deflectors can be close to the racks to attract the heat emitted by the electrical components on the racks. The deflectors can rotate on the racks via the shafts, thereby adjusting the angle of the deflectors. The air blown downwards into the cabinet by the fan comes into contact with the inclined deflectors and can be directed towards the racks, thereby carrying away the heat emitted by the electrical components on the racks, effectively eliminating dead zones in airflow and improving heat dissipation.

[0018] In the above solution, the heat dissipation fins on the surface of the air deflector can absorb the heat emitted by the electrical components on the rack, preventing local heat accumulation. Furthermore, the air blown downwards into the cabinet by the fan comes into contact with the inclined air deflector, which can quickly carry away the heat and effectively improve the heat dissipation speed.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4The present invention provides a power distribution cabinet with good heat dissipation performance, comprising: a cabinet body 1, a cabinet door 2, a mounting rack 3, a surface-mount temperature sensor 4, a fan 5, a frame 6, a rotating shaft 7, a guide plate 8, heat dissipation fins 9, and an exhaust fan 10. A ventilation chamber 101 is provided at the top of the cabinet body 1, and an exhaust chamber 102 is provided at the bottom of the cabinet body 1. The cabinet door 2 is installed on the front of the cabinet body 1. The mounting rack 3 is installed at the rear end of the cabinet body 1. The surface-mount temperature sensor 4 is installed on the side of the mounting rack 3. The fan 5 is installed inside the ventilation chamber 101. The exhaust fan 10 is installed inside the exhaust chamber 102. The frame 6 is installed on the back of the cabinet door 2. The guide plate 8 is installed on the inner side of the frame 6 through the rotating shaft 7. Heat dissipation fins 9 are installed on the surface of the guide plate 8.

[0030] In this embodiment, the ventilator 5 is connected to the ventilation opening at the top of the ventilation chamber 101. The lower end of the ventilation chamber 101 is provided with an air outlet, and the air outlet of the ventilator 5 is directly facing the air outlet of the ventilation chamber 101. The ventilator 5 can draw in external air and blow it down from the ventilation chamber 101 into the cabinet 1, so that the cabinet 1 keeps the air circulating.

[0031] In this embodiment, three sets of racks 6, rotating shafts 7 and guide plates 8 are provided on the back of the cabinet door 2. The three sets of racks 6, rotating shafts 7 and guide plates 8 are distributed at equal intervals. When the guide plate 8 is placed at an angle, some of the air comes into contact with the guide plate 8 and blows towards the side of the placement rack 3. There are gaps between the three sets of guide plates 8, which facilitates air circulation.

[0032] In this embodiment, the frame 6 is installed on the left and right sides of the door frame edge on the back of the cabinet door 2. The frame 6 is rectangular and horizontally arranged. The other end of the frame 6 extends to the lower end of the air outlet of the ventilation chamber 101, so that when the cabinet door 2 is closed, the frame 6 and the guide plate 8 can be close to the placement rack 3 to attract the heat emitted by the electrical components on the placement rack 3.

[0035] In this embodiment, the air guide plate 8 is rectangular, and several sets of heat dissipation fins 9 are horizontally installed on the surface of the air guide plate 8. The air blown into the cabinet 1 by the fan 5 comes into contact with the inclined air guide plate 8 and can be inclined to the placement rack 3 for airflow, thereby taking away the heat emitted by the electrical components on the placement rack 3, effectively eliminating dead corners in airflow and improving the heat dissipation effect.

[0036] In this embodiment, the heat dissipation fins 9 are rectangular strips with gaps between them. The heat dissipation fins 9 on the surface of the guide plate 8 can absorb the heat emitted by the electrical components on the rack 3, preventing local heat accumulation. Furthermore, the air blown downwards into the cabinet 1 by the fan 5 comes into contact with the inclined guide plate 8, which can quickly remove the heat and effectively improve the heat dissipation speed.
