Abstract
Department of Printed Electronics Engineering, Sunchon National University, Suncheon 540-742, Korea(Received July 21, 2014; Revised August 28, 2014; Accepted September 11, 2014)Abstract: In this paper, thermal analysis of HDU (Heat Dissipation Unit) for infrared CCTV is performed by using SolidWorks Simulation (Thermal analysis) package, in order to change the part materials and HDU shape is optimized. Furthermore, HDU disperses the aggregated heat around the LED inside the housing. The junction temperature of infrared LED checked by HDU check was 65.83℃, 42.02℃, respectively. In addition, the Thermoelement by changing the shape of the HDU was possibly designed and equipped with. Comparison with simulation and prototype measurement results, without HDU model was 65.83℃, 61.99℃, respectively. In addition to with HDU model was 42.02℃, 39.01℃, respectively. Only HDU mounted into infrared CCTV is usable in the ordinary house or outdoors. Also HDU with thermal element, fan mounted into infrared CCTV is usable in a blast furnace workplace or high temperature workplace.Keywords: IR CCTV, CCTV, IR LED, Thermal dissipation
