[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0033] like Figure 1 As shown, the outdoor cabinet of the embodiment of the utility model includes a cabinet body 1, a temperature regulating device 2, an opening and closing device 3 and a temperature control device 4.

[0034] The cabinet 1 is provided with an air outlet 13 at the top and an air inlet 14 at the bottom. Figure 1 As shown, the cabinet body 1 as a whole can be in the shape of a rectangular parallelepiped, and the air outlet 13 and the air inlet 14 can both be rectangular openings. In some other embodiments, the air outlet 13 and the air inlet 14 can also be circular, triangular, pentagonal or other hole-shaped structures, and the air outlet 13 can be located directly above the air inlet 14.

[0035] Under normal circumstances, the heat generated by the electrical components in the cabinet 1 will be discharged through the top air outlet 13 due to its low density. After being discharged, negative pressure will be formed in the cabinet 1 and cold air can be sucked into the cabinet 1 from the bottom air inlet 14, thereby meeting the need for natural heat dissipation and cooling.

[0036] The temperature control device 2 is disposed in the cabinet 1 and is used to cool the cabinet 1. Figure 1 As shown, the temperature regulating device 2 can be a heat dissipation air conditioner, and the temperature regulating device 2 can be fixed to the right cabinet wall of the cabinet 1 by fasteners such as screws. When the temperature regulating device 2 is turned on, the temperature regulating device 2 can provide cold air into the cabinet 1, thereby achieving temperature reduction regulation of the temperature in the cabinet 1.

[0037] The air outlet 13 and the air inlet 14 of the cabinet 1 are both provided with an opening and closing device 3, and the opening and closing device 3 is used to realize the opening and closing adjustment of the air outlet 13 and the air inlet 14. Figure 1 As shown, the opening and closing device 3 can be a structure such as a blade, a door panel, a window, etc. The opening and closing device 3 can be opened or closed automatically, so as to achieve the blocking or opening of the air outlet 13 and the air outlet 13.

[0038] like Figure 1 As shown, the temperature control device 4 is provided in the cabinet 1 and is used to monitor the temperature in the cabinet 1. For example, the temperature control device 4 may include a temperature sensor and a controller, etc., and the opening and closing device 3, the temperature regulating device 2, etc. are all electrically connected to the temperature control device 4. The temperature sensor can monitor the temperature in the cabinet 1 in real time.

[0039] When the temperature in the cabinet 1 is higher than the first threshold, the temperature control device 4 can control the temperature regulating device 2 to start and realize the temperature reduction regulation in the cabinet 1, and the temperature regulating device 2 can realize the forced heat dissipation regulation of the temperature in the cabinet 1. At the same time, the temperature control device 4 can also control the two opening and closing devices 3 to block and close the air inlet 14 and the air outlet 13 respectively, so that the environment in the cabinet 1 is relatively independent and sealed, so as to ensure the temperature regulation efficiency and temperature regulation effect of the temperature regulating device 2.

[0040] As the temperature regulating device 2 adjusts the temperature inside the cabinet 1, when the temperature inside the cabinet 1 is lower than the second threshold value, the temperature control device 4 can control the temperature regulating device 2 to close, thereby timely blocking the temperature regulating device 2. At the same time, the temperature control device 4 will also control the two opening and closing devices 3 to operate and open the air inlet 14 and the air outlet 13 respectively, so that the heat dissipation of the cabinet 1 can be switched from forced heat dissipation to natural heat dissipation.

[0041] It should be noted that the second threshold value can be smaller than the first threshold value. For example, the first threshold value can be 35°C and the second threshold value can be 30°C. This differentiation can extend the duration of the natural heat dissipation mode, avoid the situation where the temperature control device 2 and the opening and closing device 3 are opened too frequently, and achieve energy-saving effect.

[0042] The outdoor cabinet of the embodiment of the utility model can realize natural heat dissipation and forced heat dissipation, and the two heat dissipation modes can be switched automatically, thereby avoiding the situation where the temperature inside the outdoor cabinet is too high, and the overall energy consumption is also low.

[0043] In some embodiments, the opening and closing device 3 includes an opening and closing member 31 and a driving assembly 32, wherein the opening and closing member 31 can be a plate-like structure, and the opening and closing member 31 can be rotatably or slidably assembled in the cabinet 1, and when the opening and closing member 31 is in action, the opening and closing member 31 has a closed position and an open position. In the closed position, the opening and closing member 31 blocks the air outlet 13 or the air inlet 14, and in the open position, the opening and closing member 31 releases the blockage of the air outlet 13 or the air inlet 14.

[0044] The driving assembly 32 is connected to the opening and closing member 31 and is used to drive the opening and closing member 31 to switch between the closed position and the open position, and the driving assembly 32 is electrically connected to the temperature control device 4. For example, the driving assembly 32 can be driven by a motor, a hydraulic cylinder, etc. When in use, the opening and closing member 31 can be driven by the action of the driving assembly 32, thereby adjusting the open position and the closed position of the opening and closing member 31.

[0045] In some embodiments, the opening and closing member 31 is rotatably mounted at the air outlet 13 or the air inlet 14, and the opening and closing member 31 is kept in the open position under the action of its own gravity. For example, the opening and closing member 31 may be a shutter, and the opening and closing member 31 may include a plurality of shutters. Under normal conditions, each shutter will be kept in a vertical direction under the action of its own gravity. At this time, the interval between two adjacent shutters forms a flow channel, so that air can pass through, meeting the use needs of through-flow under natural heat dissipation.

[0046] In some embodiments, the driving assembly 32 includes a connecting rod mechanism 321 and a linear drive 322, the opening and closing member 31 includes multiple shutters, and the multiple shutters are all connected to the connecting rod mechanism 321. The linear drive 322 is connected to the connecting rod mechanism 321 and is used to drive the multiple shutters to swing through the connecting rod mechanism 321.

[0047] For example, Figure 2As shown, the linear drive 322 can be an electric push rod, and the connecting rod mechanism 321 can include a first connecting rod and a second connecting rod. One end of the first connecting rod can be hinged to the linear drive 322, and the other end of the first connecting rod can be hinged to the second connecting rod. The hinge position can be assembled with a long hole, that is, the end of the linear drive 322 can slide relative to one end of the first connecting rod, and the connection between the first connecting rod and the second connecting rod can also slide relatively. Multiple shutters can be hinged to the second connecting rod. The middle part of the first connecting rod can be rotatably assembled with the cabinet body 1, so that the first connecting rod can form a lever-like structure.

[0048] When in use, the linear drive 322 can drive the first connecting rod to swing, and the first connecting rod can pull the second connecting rod to swing, thereby realizing the opening and closing adjustment of multiple shutters.

[0049] In some embodiments, Figure 1 As shown, the cabinet 1 includes a cabinet body 11 and a top cover 12 disposed on the top of the cabinet body 11. For example, the top cover 12 may be in the shape of a roof, and the top cover 12 may be fixed to the top of the cabinet body 11 by means of fasteners such as screws. The circumferential edge of the top cover 12 overhangs to the outside of the cabinet body 11 and forms a top eave 121, that is, the radial dimension of the top cover 12 is slightly larger than the radial dimension of the cabinet body 11, so that the edges of the top cover 12 can overhang to the outside of the cabinet body 11. Specifically, Figure 3 shown.

[0050] like Figure 3 As shown, the bottom surface of the top eave 121 is provided with a plurality of heat dissipation holes 123, which may be waist-shaped holes. A channel 122 is provided in the top cover 12, and the channel 122 is connected between the air outlet 13 and the plurality of heat dissipation holes 123. Figure 1 As shown, the top cover 12 may be a cavity structure, the air outlet 13 and the heat dissipation holes 123 are both arranged on the bottom side of the top cover 12, the air outlet 13 may be arranged in the middle of the top cover 12, and the plurality of heat dissipation holes 123 may be arranged at the circumferential edge of the top eaves 121. When in use, the airflow in the cabinet body 11 may enter the channel 122 of the top cover 12 through the air outlet 13, and then may flow out through the plurality of heat dissipation holes 123.

[0051] This design allows the openings of the heat dissipation holes 123 to face downward, thereby hiding the heat dissipation holes 123 and preventing rainwater from easily entering the cabinet body 11 through the heat dissipation holes 123 .

[0052] In some embodiments, the top eaves 121 extend along the circumference of the cabinet body 11 to form a circle, and the plurality of heat dissipation holes 123 are arranged at intervals along the circumference of the top eaves 121. Figure 3As shown, the top eave 121 may be in a square ring shape, and a plurality of heat dissipation holes 123 may be provided on the bottom side of the top eave 121 and may be arranged at equal intervals along the circumference of the top eave 121. This ensures the consistency of heat dissipation in all directions.

[0053] In some embodiments, Figure 1 As shown, the opening and closing device at the air outlet 13 is located in the top cover 12, the opening and closing device at the air inlet 14 is located in the cabinet body 11, the temperature control device 4 is arranged on the inner wall surface of the cabinet body 11, and the temperature regulating device is arranged on the outer wall surface of the cabinet body 11. Thus, the opening and closing device and the temperature control device 4 can be shielded and protected, and secondly, the internal space of the cabinet body 1 can be fully utilized.

[0054] In some embodiments, the cabinet wall of the cabinet body 11 is provided with a heat-insulating layer 15. Figure 1 and Figure 2 As shown, the insulation layer 15 can be made of some insulation materials, and a sandwich layer can be provided inside the cabinet wall of the cabinet body 11, and the insulation layer 15 can be filled in the sandwich layer, so as to achieve a better isolation and protection effect.
