Description

A power distribution cabinet with heat dissipation function

technical field

The utility model relates to the technical field of electrical cabinets, in particular to a power distribution cabinet with a heat dissipation function.

Background technique

The power distribution cabinet is a center for the integration and control of electrical circuits. It is a general circuit distribution box for all users to use electricity. It is similar to the human brain and controls the central system that controls the operation of the entire device or circuit, and feeds back various information. The work content is not only easy to manage, but also conducive to maintenance when a circuit failure occurs. It is a complete set of equipment for centralized installation of switches, meters and other equipment. It can be seen that the electric cabinet box plays a very important role in the electrical management equipment, so it is important for the electric cabinet The requirements for various indicators and parameters of the cabinet are also quite strict, one of which is that the heat dissipation requirements for the electric cabinet are also very important, because the temperature inside the electric cabinet is not easy to be too high, once it is too high, it is easy to make the electric cabinet The components and parts inside the box are damaged by heat, alarm occurs, and even serious situations such as fire occur. The heat dissipation air vents on the front or side of the cabinet can not solve the heat dissipation inside the electric cabinet well, because the air intake from the side is too passive and cannot form a stable air flow, especially in the case of leeward wind. There is a vortex air flow state at the air inlet, so the air intake will be slow, so that it cannot effectively dissipate the heat inside the electric cabinet.

Based on this, the utility model designs a power distribution cabinet with heat dissipation function.

As shown in Figure 1, Figure 2 and Figure 3: a power distribution cabinet with heat dissipation function, including an electric cabinet box 1 and an air intake system arranged at the lower end inside the electric cabinet box 1, which is arranged on the upper side of the inside of the electric cabinet box 1 The air exhaust system is arranged on the shield assembly 5 outside the lower end of the electric cabinet box 1, and the air intake system includes an inner leg 9 arranged at the inner lower end of the electric cabinet box 1, and a filter mesh 14 arranged on the inner leg 9, And the intake fan 10 that is arranged on the filter mesh film 14, the exhaust system includes the upper leg 13 that is arranged on the upper end side of the electric cabinet box 1, and the exhaust fan 12 that is arranged on the upper leg 13, the electric cabinet The lower end of the box 1 is provided with a support leg 2, and the support leg 2 is provided with a support 3. The support 3 is hinged with the shielding assembly 5 through the lower rotating shaft 4. The lower end of one side of the electric cabinet box 1 is provided with a lower hook 7. The edge of the upper end surface of the electric cabinet box 1 An upper hook 11 is arranged at the position, and the shielding assembly 5 includes a circular housing 501, a rotating shaft 505 arranged at the center of the housing 501, a turbine spring 502 arranged on the rotating shaft 505, a shielding cloth 503 arranged on the turbine spring 502, and The circular tube 504 outside the casing 501, the turbine spring 502 is arranged inside the casing 501, and one side of the casing 501 is provided with an opening, and the shielding cloth 503 passes through the opening and is connected with the turbine spring 502 at one end, and connected with the casing at the other end. The round pipe 504 outside the body 501 is connected, the round pipe 504 is connected with one end of the stay rope 6, the other end of the stay rope 6 is connected with the pull hook 8, the lower end surface of the electric cabinet box 1 is provided with a round hole for air intake, and the upper end of the electric cabinet box 1 is The sides are provided with through holes for exhaust.

According to the above structure, it is not difficult to see that when the air intake fan 10 is turned on and running, the air intake fan 10 will drive the air outside the electric cabinet box 1 to the inside of the electric cabinet box 1 through the air intake round hole at the bottom of the electric cabinet box 1, After being filtered by the filter film 14, it enters the inside of the electric cabinet box 1, and the incoming cold air will air-cool the electrical components inside the electric cabinet box 1, so as to achieve the effect of cooling the electrical components inside the electric cabinet box 1, and at the same time The exhaust fan 12 installed on the electric cabinet 1 will discharge the air with heat to the outside of the electric cabinet 1, no matter what state the electric cabinet 1 is in, leeward (headwind) or downwind, it will never It will affect the entry of wind flow from the bottom of the electric cabinet 1, so it will not affect the heat dissipation requirements of the electric cabinet 1, and the heat dissipation effect of the electrical components inside the electric cabinet 1 can always be completed.

When the electric cabinet 1 stops running, the interior of the electric cabinet 1 does not need to dissipate heat. At this time, the previous technology did not involve the protection design of the sanitary conditions inside the electric cabinet 1, so at this time Dust will enter the inside of the electric cabinet 1 because of the air intake holes on the side of the electric cabinet 1. After the dust enters, it will affect the electrical components inside it, thereby reducing the life of the electrical components. So far, the shielding assembly designed by the utility model 5 will effectively protect the vent hole of the electric cabinet box, only need to move the pull hook 8 manually, and the pull rope 6 will be driven by the pull hook 8, and the other end of the pull rope 6 will drive the shielding cloth on the shield assembly 5 503 is driven, and the shielding cloth 503 is set on the turbine spring 502. Due to the winding performance of the turbine spring 502 itself, the shielding cloth 503 hidden in the shielding assembly 5 will be dragged out under the action of the turbine spring 502. When the shielding cloth 503 is extended to a certain length, especially when the air inlet and the exhaust port on the electric cabinet box 1 are blocked simultaneously along the bottom surface and the side of the electric cabinet box 1, the shielding cloth 503 can maintain a shielding state. , so that the hook 11 that is arranged on the upper end of the electric cabinet 1 side will fix the drag hook 8, so that the shielding cloth 503 reaches the protective effect that the inside of the electric cabinet 1 cannot enter dust.

Wherein: when the shielding component 5 is not used, that is to say, when the electric cabinet box 1 is working, the stay rope 6 has a certain initial length, and one end of the stay rope 6 is in contact with the pull-down hook 7 at the lower end of the side of the electric cabinet box 1 Coordinated, the length of the pull rope 6 is just set at the position of the air inlet at the bottom of the electric cabinet 1, and there is no covering cloth 503 to cover the initial state of the power distribution cabinet 1, so this will not affect the air intake demand of the electric cabinet 1 up.

For this reason, the utility model ensures that the effect of air intake and heat dissipation can be effectively achieved under any air flow direction by setting the air intake system at the bottom of the electric cabinet, and the shielding assembly arranged at the bottom is very good It ensures the clean and hygienic effect of protecting the interior of the electric cabinet when the electric cabinet is inactive.
