[0018] Figure 2 yes Figure 1 A partial enlarged view of part A. DETAILED DESCRIPTION

[0019] Combine the following Figure 1 to Figure 2 The technical solution of the utility model is further illustrated by specific embodiments.

[0020] like Figure 1 and Figure 2 The energy-saving ventilation and heat dissipation cabinet shown includes: a cabinet body 1, an air distribution kit, a fan 16 and a controller 13. A door panel 2 is provided on the front of the cabinet body 1. The door panel 2 is connected and fixed by a hinge for easy opening to place equipment.

[0021] Racks 3 are arranged at intervals in the upper and lower parts of the cabinet 1, and the devices are placed on the racks 3 at corresponding heights. Temperature sensors 11 connected to the controller 13 are arranged on the racks 3 to monitor the temperature of the devices on the racks 3 and to perform targeted ventilation and heat dissipation when the temperature is high. The number of the racks 3 is 2 to 4. In this embodiment, 4 racks 3 are used, and the devices are placed in the cabinet 1 in 4 layers.

[0022] In this embodiment, the air distribution kit includes an outer sleeve 8 and a core tube 9, and the outer sleeve 8 is vertically arranged in the cabinet 1. Figure 2 As shown, a sealing cover 15 is provided at the bottom of the outer sleeve 8 to seal the bottom of the outer sleeve 8 to prevent air leakage. The sealing cover 15 can also be fixed to the bottom of the cabinet 1 by screws to improve the stability of the outer sleeve 8.

[0023] like Figure 2 As shown, the outer sleeve 8 is provided with cold air outlets 4 corresponding to the racks 3 at intervals above and below, and natural fresh air blows toward the equipment on the racks 3 through the cold air outlets 4, taking away the heat from the equipment, and performing active ventilation and heat dissipation. An exhaust port 6 is provided on one side of the cabinet 1 to exhaust air and relieve pressure, thereby improving air fluidity. A filter screen 5 is provided in the exhaust port 6, which can prevent external dust and mosquitoes from entering the cabinet 1 through the exhaust port 5.

[0024] like Figure 1 As shown, the fan 16 is arranged at the back of the cabinet 1, and an air supply pipe 14 is arranged between the air outlet end of the fan 16 and the outer circle lower part of the outer sleeve 8, and the natural fresh air from the outside is sent into the outer sleeve 8 through the fan 16. The core tube 9 is rotatably arranged in the outer sleeve 8. In this embodiment, the inner diameter of the outer sleeve 8 corresponds to the outer diameter of the core tube 9, and the fit is tight, so that the fresh air in the outer sleeve 8 enters the core tube 9.

[0025] like Figure 2 As shown, the core tube 9 is provided with valve holes 10 corresponding to the cold air outlets 4 at intervals above and below, and the upper and lower valve holes 10 are mutually offset in the circumferential direction of the core tube 9, while the cold air outlets 4 are at the same circumferential position in the core tube 9, both pointing to the storage rack 3. Therefore, by rotating the core tube 9, the cold air outlets 4 at corresponding height positions can be opened and closed by utilizing the overlap or offset of the valve holes 10 and the cold air outlets 4.

[0026] In this embodiment, the valve hole 10 adopts a vertically extending waist hole structure with a large span in the height direction, corresponding to the cold air outlet 4, and can improve the air outlet effect. The cabinet 1 is provided with a motor 7 located above the core tube 9, and the shaft of the motor 7 extends downward into the outer sleeve 8. The top of the core tube 9 is provided with a turntable 12 connected to the shaft of the motor 7 to drive the rotation of the core tube 9.

[0027] The controller 13 is connected to the motor 7 for rotation control. When the temperature sensor 11 detects that the temperature of the equipment on the corresponding rack 3 is high, the controller 13 controls the rotation of the motor 7, driving the rotation of the core tube 9, so that the valve hole 10 at the corresponding height of the rack 3 coincides with the cold air outlet 4, and the natural fresh air in the core tube 9 enters the cold air outlet 4 through the valve hole 10 and blows toward the equipment on the rack 3 at the corresponding height, taking away the heat on the equipment, strengthening the ventilation and heat dissipation of the corresponding equipment, and improving the automation level.
