[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0028] It should also be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 7 As shown, a built-in heat dissipation electrical control cabinet includes a base 1, a main unit cabinet 2, and a top cover 3 that are fixedly connected from bottom to top. This type of electrical control cabinet can be better placed outdoors.

[0031] The connection structure of the three is as follows: hole B8 is set on the main unit cabinet 2 and bolted to hole A5 on the base 1. Hole B1 is also set on the main unit cabinet 2 and bolted to hole C1 on the top cover 3. Among them, A1A2A3 (located on the top of the base 1) and B5B6B7 (located on the bottom of the main unit cabinet 2) are aligned (input and output harnesses are routed through holes A1A2A3).

[0032] Specifically, such as Figures 1 to 5As shown, a trapezoidal groove 11 extending along the length direction is provided on the bottom surface of the base 1, and a vent 12 extending vertically through the trapezoidal groove 11 is also provided on the base 1. A first fan 21, connected to the interior, is provided at the bottom of the main unit cabinet 2, and the first fan 21 can be installed inside the vent 12. The main unit cabinet 2 contains several electronic components, a frequency converter 22, and a second fan 23 installed at its top and connected to the top cover 3. The top cover 3 has an eaves structure, and its bottom surface area is larger than the top surface area of ​​the main unit cabinet 2. Exhaust vents 31 are provided on the bottom surface of the top cover 3 around the main unit cabinet 2. A fan 24 is installed inside the frequency converter 2.

[0033] Furthermore, the main unit cabinet 2 is equipped with a horizontal adjustment plate frame 27, a vertical adjustment plate frame 28, and a cable tray frame 29 for the distribution of electronic components.

[0034] The first fan 21 draws cold air into the main unit cabinet 2, and the cold air and fan 24 dissipate heat for the electronic components and frequency converter 22. The second fan 23 and exhaust vent 31 discharge the gas required for heat dissipation to the outside of the electrical control cabinet.

[0035] Specific heat dissipation path:

[0036] The first fan 21 operates to provide cooling air into the main unit cabinet 2. At least two built-in fans 24 inside the inverter 22 operate to provide cooling air into the inverter 22, while simultaneously drawing hot air from inside the inverter 22 and exhausting it. This process dissipates heat and cools the electronic components inside the inverter 22. A second fan 23 is installed inside the main unit cabinet 2, creating a flow field inside the main unit cabinet 2 (the first fan 21 draws in cool air, and the second fan 23 draws in hot air from the cabinet and exhausts it), dissipating the heat in the main unit cabinet 2 to the top cover 3 and then exhausting it to the outside of the main unit cabinet 2 through the exhaust port 31 on the top cover 3.

[0037] like Figures 1 to 7 As shown, a main door 25 is provided on one side of the main unit cabinet 2. The main door 25 enables the electrical control cabinet to better protect the electronic components inside. A perforated door frame 251 is provided on the main door 25, and a display panel 252 protected by a transparent acrylic sheet is installed on the perforated door frame 251, which makes it easy to view the operating parameters inside the electrical control cabinet.

[0038] The perforated door frame 251 features a reverse bend design around its perimeter, extending outwards towards the main door 25. This design effectively prevents rainwater penetration, making the control cabinet more adaptable to outdoor environments and providing protection. (The main unit cabinet 22 also features a reverse bend design around point D2 to prevent rainwater penetration.)

[0039] Furthermore, multiple clips 253 are provided on the inner side of the main door 25 for fixing and positioning the wire harness.

[0040] As Figures 1 to 3 shown, in order to further protect electronic components, a secondary door 26 is also arranged on the main cabinet group 2, the secondary door 26 is located on the same side of the main cabinet group 2 as the main door 25, and the secondary door 26 is located on the inner side of the main door 25. By arranging the secondary door 26, the outdoor environment can be more adapted and protected.

[0041] The surface of the secondary door 26 is provided with multiple openings 261 for operating electronic components, which facilitates the operation of electronic components, avoids contact with high voltage hazards, and also allows observation of the running condition of the frequency converter 22.

[0042] When electronic components need to be installed or repaired, in order to facilitate operation, a built-in door handle 262 is arranged on the surface of the secondary door 26.

[0043] As Figures 1 to 3 shown, the main cabinet group 2 is provided with an alarm display 30, which can issue an alarm to prompt when the electric control cabinet is damaged.

[0044] The above is the description of the embodiments of the present application, through the above description of the disclosed embodiments, the person skilled in the art can realize or use the present application. Various modifications of these embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
