In addition, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0029] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0030] like Figures 1 to 4 As shown, this utility model discloses a capacitor bank with a cooling air duct structure, comprising a cabinet body, a main frame 10, a front door panel assembly 20 located at the front end of the main frame 10, and a rear door panel assembly 30 located at the rear end of the main frame 10. The front door panel assembly 20 includes multiple vertically arranged heat dissipation areas 21, each with multiple closely arranged first heat dissipation holes 22. The rear door panel assembly 30 is provided with a cooling fan 31, a first ventilation grille 32, and a second ventilation grille 33, the heights of which decrease sequentially. Specifically, the height of the heat dissipation areas 21 is between the first ventilation grille 32 and the second ventilation grille 33. It should also be noted that the outer side of the cabinet is the air outlet side, and the inner side is the air inlet side; the cooling fan 31 can blow the air inside the cabinet out to the outside environment.
[0031] During operation, the internal temperature of the capacitor cabinet is higher than the external ambient temperature due to the heat generated by the capacitors, inductors, and other components. When the cooling fan 31 is activated, the hot air inside the cabinet is exhausted; cooler air from the outside environment is introduced into the cabinet through the first ventilation grille 32, the second ventilation grille 33, and the first heat dissipation hole 22. Therefore, a cooling effect is formed inside the cabinet... Figure 3 The airflow duct shown has a height that decreases sequentially from the first ventilation grille 32, the first heat dissipation hole 22, and the second ventilation grille 33. Since they are located on the front and rear sides of the cabinet respectively, the airflow duct can fill the cabinet, thereby removing the working heat of the components to a large extent, improving heat dissipation efficiency, and ensuring the normal use of the capacitor cabinet.
[0032] Please see Figure 2 The front door panel assembly 20 includes a first movable front door 23 and a fixed front door 24. The first movable front door 23 is hinged to the main frame 10, and the fixed front door 24 is fixedly connected to the main frame 10 and located at the lower end of the first movable front door 23. Specifically, a heat dissipation area 21 is provided on the first movable front door 23. Figure 4As shown, the fixed front door 24 is provided with multiple horizontally arranged protrusions 25. The vertical cross section of the protrusions 25 is an isosceles trapezoid. In addition, the two sides of the protrusions 25 are provided with second heat dissipation holes 251. Ambient air can enter the cabinet through the second heat dissipation holes 251 to ensure heat dissipation of the components at the bottom of the cabinet. At the same time, the protrusions 25 and the second heat dissipation holes 251 on both sides can block some dust.
[0033] Please see Figure 2 The first heat dissipation hole 22 is a long strip extending along the width of the main frame 10; a large heat dissipation area 21 is provided to increase the air intake area of the front door panel assembly 20 and improve heat dissipation efficiency. At the same time, in order to prevent external dust from entering the cabinet through the first heat dissipation hole 22, a mesh (not shown in the figure) is provided on the inward side of the front door panel assembly 20. The mesh is set corresponding to the heat dissipation area 21, and the mesh plays a role in blocking dust and external substances, thus playing a dustproof role.
[0034] Other examples Figure 3 As shown, a support frame 40 for supporting components is provided inside the cabinet. The support frame 40, near the rear door panel assembly 30, includes a first working area 41, a second working area 42, and a third working area 43 arranged sequentially from top to bottom. For ease of later operation, the front door panel assembly 20 also includes a second movable front door 26 and a third movable front door 27. The second movable front door 26 is hinged to the main frame 10 and located above the first movable front door 23; the third movable front door 27 is hinged to the main frame 10 and located above the second movable front door 26. The third movable door corresponds to the first working area 41; the second movable front door 26 corresponds to the second working area 42; and the first movable front door 23 corresponds to the third working area 43.
[0035] Please see Figure 1 The rear door panel assembly 30 includes a double door 34 and an upper rear door 35; the double door 34 includes a symmetrically distributed left rear door 341 and a right rear door 342, both of which are hinged to the main frame 10; the upper rear door 35 is located at the upper end of the double door 34 and is hinged to the main frame 10.
[0036] Specifically, the top of the left rear door 341 and the right rear door 342 includes a top surface 343, and the bottom of the left rear door 341 and the right rear door 342 includes a bottom surface 344. Both the left rear door 341 and the right rear door 342 have a first mounting hole 345 and a second mounting hole 346, with the first mounting hole 345 located near the top surface 343 and the second mounting hole 346 located near the bottom surface 344. A cooling fan 31 is mounted in the first mounting hole 345, and a second ventilation grille 33 is mounted in the second mounting hole 346, thus ensuring that the second ventilation grille 33 is located below the cooling fan 31. Simultaneously, the first mounting hole 345 and the second mounting hole 346 are vertically aligned, placing the cooling fan 31 and the second ventilation grille 33 in the same vertical plane, resulting in a more concentrated airflow and improved airflow efficiency. Specifically, a third mounting hole 351 is provided in the middle of the upper rear door 35, and the first ventilation grille 32 is mounted in the third mounting hole 351.
[0037] Compared to existing technologies, the capacitor cabinet with a cooling air duct structure involved in this utility model includes a cabinet body, which includes a main frame 10, a front door panel assembly 20, and a rear door panel assembly 30. The rear door panel assembly 30 has a cooling fan 31 in the middle, a first ventilation grille 32 on its top, and a second ventilation grille 33 on its bottom. The front door panel assembly 20 includes multiple heat dissipation areas 21, each with a plurality of closely arranged first heat dissipation holes 22. The cooling fan 31 and the first ventilation... The first ventilation grille 32, the second ventilation grille 33, and the first heat dissipation hole 22 form an airflow system; it can exhaust hot air inside the cabinet and introduce cold air from the outside, preventing the internal temperature of the cabinet from becoming too high and affecting the normal use of the capacitor cabinet; in addition, the first ventilation grille 32 and the second ventilation grille 33 are arranged opposite each other at the upper and lower ends of the cooling fan 31, and the height of the first heat dissipation hole 22 is located between the first ventilation grille 32 and the second ventilation grille 33. Through the above structure, the exchange efficiency between the air inside the cabinet and the outside air is improved, thereby improving the heat dissipation efficiency of the capacitor cabinet.
[0038] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
