차량용 램프 내열 예측 프로그램 개발을 위한 열전달 실험

다국어 초록 (Multilingual Abstract)

The heat from bulbs of automotive lamp is transferred to internal materials in the form of conduction, convection and radiation. The transferred heat causes deformation of lamp materials when it exceeds the heat-resistance limits. To reduce the effort from trial and error by failing the heat-resistance test after designing and producing lamps, using a simulation program is necessary at the design stage. A new in-house heat-resistance prediction program with less errors is going to be developed, which covers conduction, convection and radiation based on experiments. The experimental facility is designed, according to variables, such as bulb powers, heat-resistant distance, boundary conditions, etc. Key parameters were set to select and perform experimental cases. The surface average temperatures were calculated, and the temperature distribution patterns of each surface were found. As a result of the experiment, the temperature distribution of all data values was different at temperature, but the shape was very similar. This shows similar heat transfer patterns throughout the data. In the case of forced convection, the temperature distribution was lower depending on the atmosphere temperature, bulb distance, and box size compared to the natural convection. By securing reliable data, algorithm development and verification program based on the experiment is possible.
