Currently, there are two main heat dissipation methods used in led street lighting luminaires: one is passive heat dissipation; Another is active heat dissipation.
Passive heat dissipation: The heat of the led street lighting luminaires is dissipated through the convection of the surface of the led street lighting luminaires with the air.
Active cooling: Increase the air flow speed of the led street lighting luminaires through water cooling and fans, and take away the heat from the heat sink.
The heat pipe is a component with excellent heat transfer performance. It is the latest led street lighting luminaires heat dissipation solution. Its consists of three parts: a closed metal pipe, a small amount of working medium and a capillary structure. It works with three physical principles:
1. In a vacuum state, the boiling point of the liquid decreases;
2. The latent heat of vaporization of the same substance is much higher than the sensible heat;
3. The suction force of the porous capillary structure on the liquid can make the liquid flow.
Since the advent of heat pipes, new developments have been made in led street lighting luminaires cooling systems. The heat pipe system requires no fans, no noise, is maintenance-free, safe and reliable, it can replace the water cooling system, saving water resources and related auxiliary equipment investment.
In addition, heat pipe cooling can also concentrate or even seal the heating parts of led street lighting luminaires and move the heat dissipation part to the outside of led street lighting luminaires, which can prevent dust, moisture, and explosion, and improve the safety and reliability and application scope of led street lighting luminaires electrical equipment.
