碩士 / 逢甲大學 / 機械與電腦輔助工程學系 / 104 / This paper discusses a high-speed motor spindle having cold vapor flow channel of fin design and use of the property of symmetry axis spindle simplify eventually reduced to a spindle 30 degrees sector, the use of 3D models to create conjugate heat transfer models and analysis spindle heat transfer.We analyse with and without fins, channel width, difference pressure and different fin materials. Through the study, we find that the best way to remove heat is the natural convection, thermal radiation, cooling channels and convection effect of rotation. In addition, the spindle temperature will be lower when the channel width, air mass flow rate and fins thermal conductivity become bigger. Finally, we find that the fluid speed can not increase effectively and make the air hotter quickly due to the spindle channel height have limit. To sum up the design of special channels is unnecessary.
