The general application of emergency triproof light's heat dissipation technology is a heat transfer plate, which is about 5 mm thick copper coins. This is counted as a temperature equalizing plate, and then the pyrogen must be heated; therefore, a modified radiator is used to develop Exhaust heat, but a lot of weight.
Therefore, many fibrous heat pipe radiators are now used. The output power of this type of heat rejection has a very large fluctuation compared with the traditional block heat pipe radiator, which can make the LED junction temperature lower than the general heat pipe radiator by about 15 ℃ On the other hand, the moisture-proof effect is better than that of heat pipe radiators of general aluminum alloy profiles, and the weight and volume can also be improved. Other graphite heat sinks developed and designed for emergency triproof light lamps with high power also have excellent heat transfer and heat dissipation effects.
The key heat dissipation methods generally include the following categories, pure natural heat convection heat removal, forced heat removal by modified electric fans, heat pipes and control loop heat pipe radiators. Modification of the forced heat exhaust method of electric fans has complicated system software and low credibility. The heat pipe and control loop heat pipe radiator method will also easily lead to increased costs. The LED lamps have the advantages of being used in the suburbs at night, the heat exhaust surface is located on the upper side and the body shape is less restricted, etc., which are beneficial to the natural gas convective heat removal. Therefore, the LED lamps should try to choose the pure natural heat convection heat removal method. Carry out heat removal.
