Numerical Prediction of the Temperature Field in Hard disk Drive

하드디스크 드라이브 내부의 온도장 예측에 관한 연구

Temperature distributions in a 3.5 inch hard disk drive including disk surface and internal air have been simulated numerically. Solutions were obtained from fifteen cases regarding three power consumption rates and five ambient conditions. As a result, the velocity of cooling air should be maintained greater than ㏐/s when the power consumption reached 3W in the disk drive. A correlation equation was proposed to predict the temperature field of disk surface and caseing surface.
