ANALYSIS OF THE ENHANCEMENT OF COOLING EFFICIENCY OF A VEHICLE IN THE ENGINE ROOM
차량 엔진룸에서의 냉각효율 향상에 관한 해석
Abstract
Flow and temperature fields of a mid-size vehicle engine room are examined numerically to analyze the enhancement of cooling efficiency of several different design cases in a front body shape. The wall temperatures of a radiator and an engine parte are utilized to predict the effects of engine cooling on the thermal environment and the cooling efficiency in an engine room. The analyzed results are the mass flow rate at the upper and lower inlets, in the radiator, and the condenser. It is shown that the shape of the front end, lay-out of the engine parts, and the presence of the undercover greatly influence the flow and temperature fields, and the enhancement of cooling efficiency in the engine room.
