[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0018] like Figures 1 to 4 In the embodiment of the AC screen cabinet ventilation device of the utility model shown, the AC screen cabinet ventilation device includes a cabinet 1, a back plate 2 is connected to the cabinet 1 by bolts, a blowing fan 3 is fixedly connected to the back plate 2, a curved panel 4 is fixedly connected to one side of the back plate 2, a plurality of ventilation holes 5 are opened on the curved panel 4, and the plurality of ventilation holes 5 are arranged in a divergent shape, the curved panel 4 is located inside the cabinet 1, the center of the concave surface of the curved panel 4 faces the blowing fan 3, a conical plate 6 is provided between the blowing fan 3 and the curved panel 4, the open end of the conical plate 6 faces the middle of the curved panel 4, and the middle of the conical plate 6 An open hole 7 is provided, and a glass door is installed on the cabinet 1. When ventilation is performed, the blowing fan 3 can be started to blow air toward the inside of the device. The wind blown by the blowing fan 3 is diffused to the surroundings of the curved panel 4 through the conical plate 6, and through the setting of the open hole 7, the wind blown by the blowing fan 3 can also be blown to the middle of the curved panel 4 through the open hole 7. Through the setting of the curved panel 4 and a plurality of ventilation holes 5 arranged in a divergent shape, the wind blown by the blowing fan 3 can be diffused to multiple angles inside the cabinet 1, thereby facilitating multi-angle and relatively uniform ventilation and heat dissipation of the inside of the cabinet 1.

[0019] In one embodiment of the present application, preferably, a dustproof net 8 is fixedly installed on one side of the blowing fan 3. The provision of the dustproof net 8 can prevent debris and fluff from being blown into the interior of the device.

[0020] In one embodiment of the present application, preferably, an arc-shaped edge 9 is integrally formed at the edge of the conical plate 6, and a support rod 10 is fixedly connected to the arc-shaped edge 9, and one end of the support rod 10 is fixedly connected to the blowing fan 3.
