터보냉동기 75 kW급 인버터 냉각용 고효율 수냉식 히트싱크 Plate 개발

The purpose of this study is to apply a water-cooled cooling system of an inverter to which the cooling system of air-cooled, increasing the cooling efficiency, by applying the water-cooled cooling system, to be compact cooling apparatus. Flow path air-cooled cooling system to design a water box cooling water flows attempts to develop a cooling device with high efficiency a water-cooled inverter as compared with the conventional inverter is applied. Flow area of the water box, the width of the fin, was analyzed pitch at fin, the height of the fin as variables. Program that is used for the analysis is a ANSYS16.1 CFX. Inlet temperature of the cooling water was fixed at 30 ° C., a heat source of the heating element 120 W, turbulence model was subjected to analysis processing by using the k-epsilon model.
