[0002] As the final stage of the power distribution system, power distribution cabinets (PDCs) integrate a variety of electrical devices. These devices generate significant heat during prolonged, high-load operation. Effective heat dissipation is crucial for ensuring equipment performance, extending service life, and preventing safety incidents. Traditional drawer-type PDCs typically use cooling fans to direct external cool air into the bottom of the drawer-type PDC, dissipating heat through natural convection of hot and cold air.
[0003] However, the drawer-type power distribution unit is fixed on the mounting frame in the form of a drawer. Although each drawer is provided with ventilation holes at the bottom and sides, the physical barrier between the drawers limits the free flow of air inside the distribution cabinet, thereby reducing the overall air flow rate, making it difficult for heat in some areas to be effectively dissipated and difficult to achieve the ideal heat dissipation effect, causing the temperature inside the distribution cabinet to easily rise, thereby affecting the performance and life of the electrical equipment.
[0004] Therefore, it is necessary to improve the heat dissipation structure of the drawer-type distribution cabinet to increase the air flow speed and heat dissipation efficiency inside the distribution cabinet, and ensure the stability and safety of electrical equipment when running under high load.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] refer to Figure 1-5A fast heat dissipation type power distribution cabinet includes a cabinet body 1 and a cabinet door 2. A power distribution installation area 11 is provided in the cabinet body 1, and a mounting frame 3 is installed in the power distribution installation area 11. An exhaust hood 4 is provided on the top of the mounting frame 3, and the exhaust hood 4 can discharge the air in the power distribution installation area 11; a plurality of drawer-type power distribution units 5 are provided on the mounting frame 3, and the drawer-type power distribution unit 5 is an integrated unit of electrical components. The drawer-type power distribution unit 5 can be inserted into the mounting frame 3. The structure of the drawer-type power distribution unit 5 and the installation of the mounting frame 3 are both existing technologies and are not repeated here; a plurality of ventilation holes are provided on the drawer-type power distribution unit 5, and the plurality of ventilation holes can be set at the bottom and side of the drawer-type power distribution unit 5, which can increase the connection area between the drawer-type power distribution unit 5 and the power distribution installation area 11, facilitate gas exchange, and realize heat dissipation of the drawer-type power distribution unit 5.
[0024] Cabinet door 2 is equipped with a heat dissipation unit 6, whose air outlet is aligned with the bottom of mounting frame 3 to deliver cool air into power distribution installation area 11. A rapid circulation member 7 is provided on the inner wall of power distribution installation area 11 and communicates with power distribution installation area 11. Rapid circulation member 7 can quickly guide hot air from the bottom of mounting frame 3 and power distribution installation area 11 into exhaust hood 4, where it is exhausted through exhaust hood 4, creating an effective hot air circulation system.
[0025] In some embodiments, the rapid circulation member 7 includes a circulation cover 71, a guide groove plate 72 and a partition plate 73. The circulation cover 71 includes a circulation cover body. The circulation cover body can be a square box. Two diverter plates are provided in the square box. A first channel 711 is formed between the two diverter plates. The diverter plates and the inner wall of the circulation cover body form a second channel 712. The diverter plates can be L-shaped plates, so that the cross-section of the first channel 711 close to the cabinet door 2 is an isosceles trapezoid, and the cross-section of the second channel 712 close to the cabinet door 2 is a right-angled trapezoid. The side of the first channel 711 close to the cabinet door 2 is larger than the side of the first channel 711 away from the cabinet door 2. Increase the amount of cold air flowing into the first channel 711; the second channel 712 close to the cabinet door 2 is smaller than the first channel 711 away from the cabinet door 2, which helps to accelerate the flow speed of air in the guide channel 74, and the two second channels 712 are symmetrically arranged at both ends of the first channel 711; a drawer-type distribution unit 5 is provided above the first channel 711, and the cold air input from the heat dissipation unit 6 to the bottom of the mounting frame 3 passes through the diversion of the circulation cover 71, and part of it passes through the first channel 711 and flows into the bottom of the drawer-type distribution unit 5, exchanges heat with the hot air inside the drawer-type distribution unit 5, forms hot air, and is finally discharged from the exhaust hood 4.
[0026] A guide slot plate 72 is connected above the second channel 712. A plurality of partition plates 73 are provided in the guide slot plate 72. A plurality of guide channels 74 are formed between the plurality of partition plates 73 and the guide slot plate 72. The guide channels 74 are connected to the exhaust hood 4. A plurality of guide holes 721 are provided on the side of the guide slot plate 72 close to the mounting frame 3. The plurality of guide holes 721 are arranged along the axial direction of the guide channel 74. The guide holes 721 are connected to the guide channel 74 and the power distribution installation area 11. Due to the diversion of the flow hood 71, the air flow velocity flowing into the guide channel 74 is greater than the air flow velocity between the first channel 711 and the exhaust hood 4. Since the guide holes 721 connect the guide channel 74 and the side area of the drawer-type power distribution unit 5, a pressure difference is formed between the guide channel 74 and the side area of the drawer-type power distribution unit 5. In the process of the hot air in the drawer-type power distribution unit 5 flowing upward into the exhaust hood 4, part of the hot air flows into the guide channel 74 under the action of the pressure difference, thereby increasing the air flow velocity in the drawer-type power distribution unit 5, accelerating the discharge of the hot air in the drawer-type power distribution unit 5, and improving the heat dissipation efficiency.
[0027] In some embodiments, the guide hole 721 may be a conical hole, with a diameter on the side facing the guide channel 74 being smaller than a diameter on the side away from the guide channel 74 , which can accelerate the air flow rate toward the guide channel 74 , thereby further improving heat dissipation efficiency.
[0028] In some embodiments, the heat dissipation unit 6 includes a louver 61, which is arranged on the outside of the cabinet door 2. A cooling fan is provided on the inside of the cabinet door 2. The air outlet area of the cooling fan covers the air inlet of the fast circulation component 7 to ensure that the cold air can be blown directly to the power distribution installation area 11; a filter plate is provided between the cooling fan and the louver 61 to prevent dust and other impurities from entering the interior of the power distribution cabinet.
[0029] In some embodiments, the exhaust hood 4 includes an air inlet portion 41 and an exhaust portion 44. Two first air inlets 42 and two second air inlets 43 are symmetrically provided at the bottom of the air inlet portion 41. The first air inlet 42 is provided above the drawer-type power distribution unit 5, and the second air inlet 43 is connected to the guide channel 74. An exhaust portion 44 is provided on the side of the air inlet portion 41 close to the cabinet door 2. The exhaust portion 44 can discharge the gas in the exhaust hood 4 out of the cabinet door 2. The air inlet portion 41 and the exhaust portion 44 are connected by a connecting portion. The cross-section of the exhaust portion 44 is smaller than the cross-section of the air inlet portion 41 to accelerate the flow of air and discharge it out of the cabinet body 1.
[0030] In some embodiments, the guide groove plate 72 and the partition plate 73 are both graphite plates, which have good thermal conductivity and high temperature resistance. The graphite plate can accelerate the heat exchange efficiency between the guide channel 74 and the gas in the side area of the drawer-type distribution unit 5, thereby improving the heat dissipation effect; at the same time, the overall design of the guide groove plate 72 and the partition plate 73 can form a fin heat dissipation structure in the peripheral area of the drawer-type distribution unit 5, further improving the heat dissipation effect.
[0031] The specific working principle is as follows:
[0032] When the power distribution cabinet begins operation, the cooling unit 6 activates, drawing in cold air from outside through the louvers 61. After being filtered by the filter plate, it is blown into the bottom of the power distribution installation area 11 by the cooling fan. The cold air enters the circulation hood 71 and is then diverted to the bottom of the drawer-type power distribution unit 5 and the bottom of the guide slot plate 72. Within the drawer-type power distribution unit 5, the cold air exchanges heat with the hot air generated by the electrical equipment, lowering the equipment temperature. The cold air then rises through the first air inlet 42 and enters the air intake section 41. Simultaneously, some of the cold air rises through the guide channel 74 formed by the partition plate 73. During this rise, as it passes through the conical guide hole 721, the air within the power distribution installation area 11 enters the guide channel 74, where it further mixes and flows, finally flowing into the air intake section 41 of the exhaust hood 4 through the second air inlet 43. After gathering in the air intake section 41, the hot air is discharged from the cabinet 1 through the exhaust section 44, forming a complete and continuous heat dissipation cycle. This effectively reduces the temperature within the power distribution installation area 11 and ensures the stable operation of the electrical equipment.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents.
