[0017] The beneficial effects of the present utility model are as follows: the setting of the side plate reduces the area of the chassis exposed to high temperature. When the fan drives the air flow for internal cooling, the air flow in the air guiding channel is also driven by negative pressure, accelerating the air to pass through the air guiding channel from bottom to top, realizing the simultaneous acceleration of the air flow movement inside and outside the box for cooling.

[0018] When the fan is not started, the air guiding channel can also produce a certain cooling effect by using the principle of hot air rising.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1 to 4 shown, an outdoor monitoring power supply chassis 100 includes: a chassis 10, a power module 20, and a switch module 30.

[0027] A partition 11 is provided inside the chassis 10, dividing the interior of the chassis 10 into an equipment cavity 111 and a wiring cavity 112. The power module 20 and the switch module 30 are located in the equipment cavity 111. A wiring module is provided in the wiring cavity 112 for external connection to devices. The equipment cavity 111 is located above the wiring cavity 112.

[0028] Side plates 101 are provided on both sides of the chassis 10. The side plates 101 are connected to the outer wall surface of the chassis 10 through two connecting ribs 102. A gas guiding channel is formed between the side plates 101 and the outer wall surface of the chassis 10. The gas guiding channel extends in the height direction.

[0029] An outdoor monitoring power supply chassis 100 further includes: a fan. Air intake holes and air outlet holes are formed on the box wall of the chassis 10. The air intake holes are located at the lower end of the wiring cavity 112. The air outlet holes are located at the upper end of the equipment cavity 111. The air intake holes communicate with the air guide channel and are close to the bottom inlet of the air guide channel. The air outlet holes are located above the top outlet of the air guide channel. The partition 11 is formed with ventilation holes. After the fan is started, it drives the air flow to enter the wiring cavity 112 from the air intake holes, pass through the ventilation holes and enter the equipment cavity 111, and then be discharged from the air outlet holes.

[0030] As a specific implementation manner, the fan includes: an intake fan 41 and an exhaust fan 42. The intake fan 41 is aligned with the air intake hole. The exhaust fan 42 is aligned with the air outlet hole. The intake fan 41 drives the air flow to enter the wiring cavity 112 from the air intake hole. The exhaust fan 42 drives the air in the equipment cavity 111 to be discharged from the air outlet hole. Both the intake fan 41 and the exhaust fan 42 are axial fans.

[0031] The number of the intake fans 41 is several; several intake fans 41 are symmetrically arranged on both sides of the chassis 10. The number of the exhaust fans 42 is several; several exhaust fans 42 are symmetrically arranged on both sides of the chassis 10. Specifically, the number of the intake fans 41 and the exhaust fans 42 is two.

[0032] As a preferred implementation manner, the air outlet direction of the air outlet hole is perpendicular to the air outlet direction of the top outlet of the air guide channel. After the fan is started, as the air flow at the air outlet hole sprays outwards, a negative pressure is generated at the top outlet of the air guide channel, accelerating the air to pass through the air guide channel from bottom to top.

[0033] Specifically, when the fan is not started, due to the operation of the equipment in the equipment cavity 111, the temperature in the equipment cavity 111 is higher than the temperature in the wiring cavity 112, so that the temperature of the upper section of the air guide channel is higher than the temperature of the lower section of the air guide channel. The hot air rises along the air guide channel and is discharged from the top outlet of the air guide channel, and the cold air enters the air guide channel from the bottom inlet of the air guide channel.

[0034] As a preferred implementation manner, the side plate 101 is made of a material with a lower thermal conductivity than the chassis 10. Specifically, the chassis 10 is a metal chassis, and the side plate 101 is a plastic plate. More specifically, the connecting rib 102 is made of a metal material. The connecting rib 102 is integrally injection-molded with the side plate 101 by an insert molding method.

[0035] As a specific implementation manner, the length of the connecting rib 102 overlapping with the equipment cavity 111 is greater than the length of the connecting rib 102 overlapping with the wiring cavity 112. The connecting rib 102 can assist the equipment cavity 111 to conduct heat outwards, increasing the heat conduction area. It also makes the air at the top of the air guide channel have a larger heat contact area.

[0036] As a specific implementation manner, the chassis 10 is further provided with a brim structure. The brim structure is located above the air guide channel to prevent foreign objects from falling into the air guide channel.

[0037] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.

[0038] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
