Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
Fig. 1, Fig. 2 and Fig. 3 are please referred to, the utility model provides a kind of technical solution: a kind of dynamic power distribution cabinet, including power
Power distribution cabinet shell 1, and dynamic power distribution cabinet shell 1 is arranged on firm banking 5,1 side of dynamic power distribution cabinet shell is provided with
The inside of multiple air inlet holes 4, the dynamic power distribution cabinet shell 1 is mainly made of power cell circuit 2 and heat sink 3, and power
Element circuit 2 is fixedly mounted on the upper surface of heat sink 3, and the inside of the dynamic power distribution cabinet shell 1 is additionally provided with air duct 6,
Exchange ventilation hole 7 is installed, and the upper end in air duct 6 is connected with exhaust fan 8, the air inlet between air duct 6 and power cell circuit 2
The upper end in hole 4 is equipped with the protection the brim of a hat 9.
Preferably, the protection the brim of a hat 9 is in polyline shaped structure；The material of the heat sink 3 uses copper clad steel material；Institute
