It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0017] See also Figure 1-3The utility model provides a technical solution: an electrical cabinet with high efficiency in heat dissipation, comprising an electrical cabinet 1, a power motor 2 is arranged on the top of the electrical cabinet 1, the bottom end of the power motor 2 penetrates the top inner wall of the electrical cabinet 1, a rotating main rod 3 is arranged on the end of the power motor 2 extending into the inner side of the electrical cabinet 1, an exhaust fan blade 4 is arranged on the surface of the rotating main rod 3, a rotating elliptical plate 5 is welded on the side of the exhaust fan blade 4 away from the center of the circle, a rotating elliptical slot 51 is opened on the top of the rotating elliptical plate 5, and an accelerating heat dissipation device is arranged on the top of the electrical cabinet 1;

[0018] The accelerated heat dissipation device includes an arc block 52, a spherical body 53, a flow hole 54, a fixing plate 55, an electric fan blade 56 and a telescopic rod 57. The arc block 52 is movably connected to the inner side of the rotating elliptical slot 51. The top of the electrical cabinet 1 is provided with a spherical body slot. The spherical body 53 is movably connected to the inner side of the spherical body slot. The top of the electrical cabinet 1 is provided with an arc limiting slot, which is connected to the spherical body slot. The surface of the spherical body 53 is equipped with an arc limiting block, which is movably connected to the arc limiting block. The movable clamping restricts the spherical body 53 so that the spherical body 53 can only rotate in the horizontal plane. The flow hole 54 is opened on the surface of the spherical body 53. The fixed plate 55 is provided with the inner ring surface of the flow hole 54. The electric fan blade 56 is arranged on the top of the fixed plate 55. The telescopic rod 57 is arranged on the top of the fixed plate 55. The bottom end of the telescopic rod 57 is movably hinged with the top of the arc block 52. There are multiple accelerated heat dissipation devices, and the multiple accelerated heat dissipation devices are arranged on the top of the electrical cabinet 1. The air intake range inside the electrical cabinet 1 is synchronously expanded through the multiple accelerated heat dissipation devices.

[0019] An air inlet slot 6 is provided on the right side of the electrical cabinet 1, and a cooling pipe 7 is provided on the rear inner wall of the electrical cabinet 1. The cooling pipe 7 is located on the left side of the air inlet slot 6. The cooling pipe 7 is curved, which expands the cooling range of the air by the cooling pipe 7. An exhaust hole 8 is provided on the top of the electrical cabinet 1.

[0020] When in use, the cooling pipe 7 is connected to the cold water pipe. When the temperature of the electrical components inside the electrical cabinet 1 is too high, the power motor 2 is started, and the power motor 2 drives the rotating main rod 3 to rotate, and the rotating main rod 3 drives the exhaust fan blades 4 to rotate. When the exhaust fan blades 4 rotate, the hot air in the central area of ​​the electrical cabinet 1 is quickly discharged upward, and at the same time, the exhaust fan blades 4 drive the rotating elliptical plate 5 to rotate, and the rotating elliptical plate 5 drives the rotating elliptical slot 51 to rotate. When the long axis of the rotating elliptical slot 51 rotates from horizontal to longitudinal, the rotating elliptical slot 51 drives the arc block 52 to move to the left under the restriction of the arc limiting block, and the arc block 52 drives the telescopic rod 57 to swing to the left with the spherical body 53 as the fulcrum, and the telescopic rod 57 drives the spherical body 53 to swing through the fixed plate 55. The telescopic rod 57 drives the electric fan blade 56 to swing to the left with the spherical body 53 as the fulcrum through the fixed plate 55. The electric fan blade 56 rotates during the swinging process to quickly discharge the hot air in the electrical cabinet 1 away from the center area. Similarly, when the long axis of the rotating elliptical slot 51 rotates from the longitudinal direction to the transverse direction, the working principle is the same as above. Similarly, the working principles of the remaining accelerated heat dissipation devices are the same as above. In the process of the exhaust fan blade 4 rotating to dissipate heat, the hot air in the electrical cabinet 1 away from the center area is accelerated to be discharged through multiple accelerated heat dissipation devices. At the same time, the cooling pipe 7 cools the air flowing into the electrical cabinet 1 through the air inlet slot 6 so that the temperature flowing into the electrical cabinet 1 is lower than that of the outside, thereby accelerating the cooling of the air to the electrical appliances in the electrical cabinet 1, thereby improving the overall cooling efficiency of the electrical cabinet 1.

[0021] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
