In this paper, thermal analysis of HDU (Heat Dissipation Unit) for infrared CCTV is performedby using SolidWorks Simulation (Thermal analysis) package, in order to change the part materials andHDU shape is optimized. Furthermore, HDU disperses the aggregated heat around the LED inside thehousing. 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 andequipped with. Comparison with simulation and prototype measurement results, without HDU model was65.83℃, 61.99℃, respectively. In addition to with HDU model was 42.02℃, 39.01℃, respectively. Only HDUmounted 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.
