광학식 대용량 정보저장장치의 냉각용 펜의 열유동 해석 = Heat and Flow Analysis for Cooling Fan for an Optical Archive System

다국어 초록 (Multilingual Abstract)

An archive system is designed to store data for a long time without loss. However, many important factors such as temperature, dust, vibration, and humidity must be considered to design a successful archive system. Read/write devices, for example optical disk drives(ODDs), in an archive system generate heat while they are in operation. Fans are usually used to remove heat but the air flow accompanies dust into the system result in system failure. In this study, an archive system with six ODDs is chosen as an analysis model and flow together with temperature distributions are computed using a CFD simulation package. Flow analysis is focused on four cooling fans at the rear panel and temperature distribution is studied for various cases of fan operation. From the temperature point of view, fans give significant effects on 4th to 6th ODDs compared to the 1st to 3rd ODDs. Also, it is noticed which fan is the most important as far as cooling is concerned.
