Simulation Analysis of Heat Dissipation Efficiency of Large LED Screens
As a popular advertising tool nowadays,large LED screens are widely used in both commercial and residential buildings.This study focuses on the large LED screens of a residential building in Jinhua City,Zhejiang Province,selects outdoor dry-bulb temperature during the summer air conditioning season,and analyze the heat dissipation,heat removal,and local heat accumulation of the screen under extreme weather conditions in summer,so as to give the distribution of temperature field and heat removal within the space.The results show that the changes of external temperature at different angles have little effects on the temperature behind the screens,while the increase of the number of fans can effectively improve the heat dissipation effect of the screens.On this basis,this paper puts forward suggestions for specific construction,serving as a reference for relevant engineering projects.
