Description

Technical Field

[0001] The utility model relates to the field of control boxes, in particular to a lighting electrical control box with enhanced heat dissipation. Background Art

[0002] The lighting electrical control box is an important part of the power system, mainly used for power distribution, protection and control of indoor electrical equipment. It is a box that integrates a variety of electrical components and equipment, which is used to centrally control and manage the lighting system. The electrical components in the control box will emit a lot of heat when working, and in order to avoid the temperature in the control box being too high, ventilation windows and cooling fans are often installed on the control box. In the existing patent application with application number CN202122138416.8, an electrical control box is proposed. Since the position of its cooling fan is fixed, the part of the control box that is far away from the cooling fan will be difficult to dissipate heat quickly and effectively. At the same time, due to the different powers of different electrical components, the heat they emit is also very different. Therefore, if the electrical components with more heat dissipation are far away from the cooling fan, the heat they emit will be difficult to be efficiently discharged. Therefore, a lighting electrical control box with enhanced heat dissipation is needed to solve the above problems. Utility Model Content

The heat sink fan 9 is fixedly installed in the frame 8, and the air guide shell 10 is fixedly installed at the inner end of the frame 8. The heat sink 3 is located on the inner side of one of the ventilation windows 6, and the frame 8 is fixedly connected to the inner wall of the control box body 1, and a plug hole 11 is opened on the air guide shell 10. An air guide duct 4 is fixedly plugged into the air guide shell 10. The air guide duct 4 is composed of a bellows 12 and a trumpet 13. The trumpet 13 is fixedly installed at one end of the bellows 12. The bellows 12 on the air guide duct 4 is fixedly plugged into the plug hole 11 opened on the air guide shell 10. A protective net 14 is fixedly installed on the inner wall of the trumpet 13. A fixing frame 5 is fixedly sleeved on the bellows 12 and near the trumpet 13. The fixing frame 5 is composed of a connecting plate 15 and a fixed magnet 16. The fixed magnet 16 is fixedly installed At one end of the connecting plate 15, a fixing magnet 16 can be adsorbed on the iron mounting plate 2. A mounting hole is provided on the connecting plate 15 on the fixing frame 5. The connecting plate 15 is fixedly sleeved on the corrugated tube 12 through the mounting hole. By setting a heat dissipation device 3, an air duct 4 is set on the heat dissipation device 3. When heat dissipation is performed, the horn tube 13 for air intake on the air duct 4 can be placed close to electrical components that dissipate more heat, so that the heat dissipation device 3 can quickly discharge the heat dissipated by the electrical components, thereby enhancing the heat dissipation of the area and reducing the accumulation of heat in the control box body 1. Finally, the heat dissipation device 3 cooperates with the air duct 4, so that the position far away from the heat dissipation fan 9 in the control box body 1 can also be effectively dissipated, avoiding the occurrence of heat dissipation dead corners, and thus making the heat dissipation effect in the control box body 1 better; by setting a fixing frame 5 and making it cooperate with the iron mounting plate 2, the position of the horn tube 13 on the air duct 4 can be easily fixed.

[0023] It should be noted that the utility model is a lighting electrical control box with enhanced heat dissipation. When in use, the electrical components can be installed and fixed on the iron mounting plate 2. During use, when an electrical component fixedly installed on the iron mounting plate 2 dissipates a large amount of heat, the heat dissipation effect of the area where the electrical component is located can be enhanced. The method is that only the trumpet tube 13 on the air duct 4 needs to be moved so that the air inlet of the trumpet tube 13 is close to the electrical component with a large amount of heat dissipation, and then the fixed magnet 16 on the fixing frame 5 is adsorbed on the iron mounting plate 2 to fix the position of the trumpet tube 13. Then the cooling fan 9 on the heat dissipation device 3 can be started to dissipate heat. In this process, the negative pressure generated by the operation of the cooling fan 9 will suck the hot air into the bellows 12 through the trumpet tube 13, and finally the hot air will be blown out by the cooling fan 9.
