공작기계 절삭유 냉각용 낮은 핀관의 열전달 성능에 관한 연구
A Study on the Performance of Heat Transfer of Low Fin Tubes Used in Cooling of the Cutting Oil of the Machine Tool
초록
Nine tubes with trapezoidal integral-fins having fin densities from 748 to 1654fpm and 10,30 grooves and finned tubes with caves of 0.55 and 0.64mm height respectively are tested. A plain tube having same diameter as the finned tubes is also tested for comparison. In case of condensation CFC-11 condensates at saturation state of 32
