When the temperature in some areas is too high, the heat dissipation effect is affected. Utility Model Content

[0005] The utility model aims to provide a low-voltage distribution box with a heat dissipation structure to solve the technical problem in the background art that the wind direction cannot be adjusted according to the heat point during the heat dissipation of electrical components in the distribution box.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] As a further solution of the utility model, an exhaust port is opened at one end of the low-voltage distribution box body, and the length of the exhaust port is equal to and opposite to the spacing between the partition plate and the docking plate.

[0009] As a further solution of the utility model, the heat dissipation assembly includes a heat conductive sheet and a heat dissipation fan. The heat conductive sheet is fixedly installed at one end of the limiting plate, passes through the limiting plate and the low-voltage distribution box, and is located at the outer end of the low-voltage distribution box.

[0010] Guide blocks are fixedly installed at both ends of the cooling fan. The cooling fan is slidably installed in the guide groove through the guide blocks.

[0014] Compared with the prior art, the low-voltage distribution box with a heat dissipation structure of the utility model has the following beneficial effects:

[0015] When heat is dissipated inside the low-voltage distribution box, the heat dissipation components can be pushed and pulled to slide up and down in the guide groove according to the high heat points inside the low-voltage distribution box, so that one group of heat dissipation components can be aligned with the heat points in the electrical components for directional heat dissipation.

[0017] When the cooling fan blows air into the low-voltage distribution box to dissipate heat, the cooling fan will conduct the external natural temperature into the low-voltage distribution box through the heat conducting sheet, which can make the air temperature blown out by the cooling fan lower and further improve the heat dissipation efficiency.

[0018] When the cooling fan is pushed to drive the guide block to slide in the guide groove, the top column in the storage tube at one end of the cooling fan will touch one end of the guide groove through the elastic force exerted by the push spring, so that the cooling fan has a damping force in the process of being pushed up and down.

[0033] When the low-voltage distribution box 1 is being cooled, the staff can push and pull the heat dissipation component 3 to slide up and down in the guide groove 203 according to the high heating points inside the low-voltage distribution box 1, so that one group of heat dissipation components 3 can be aligned with the heating points in the electrical components for directional heat dissipation. The slidable heat dissipation component 3 can be used by the staff to reasonably adjust the heat dissipation wind direction, which can be optimized according to the actual heating conditions of the equipment, thereby avoiding ineffective heat dissipation and improving the energy efficiency of the entire heat dissipation.
