Description

Technical Field

[0002] The electric control box is a device that integrates power control, protection and monitoring. It is usually composed of three parts: power control, output signal and input signal. The electric control box has multiple functions and effects, such as realizing automatic control, load protection, remote monitoring, energy saving and consumption reduction, etc. They are widely used in urban construction and industrial production, such as traffic light control, lighting equipment control, water pump control, factory automation and other fields. Usually, when dissipating the heat generated by the electronic components inside the electric control box, a fan is needed to absorb the heat and then discharge the heat from the top of the electric control box.

[0003] When the existing heat dissipation device of the electric control box dissipates the heat generated by the internal electronic components when they are working, it only absorbs the heat inside the box through the fan and then discharges it at the top of the box. However, the heat generated in the location where the electronic components are installed is large. Due to the lack of a mechanism to quickly dissipate the heat in the location with more heat, the heat absorption efficiency is poor. Based on this, we propose a heat dissipation device for the electric control box. Utility Model Content
