摘要

農試型落花生聯合收穫機油動力系統中液壓油之冷卻效率，受到動力系統組件摩擦損失及洩壓閥洩壓損失之影響；其中尤以洩壓所導致之熱損失為最，佔系統所產生全部熱量之50%以上。因此要降低油壓系統之作業油溫，最直接之途徑為使用經濟合理之油壓組件如泵、馬達等。同時，若油壓系統以空氣為熱交換介質時，其冷卻效率亦可經由選擇最佳冷卻面積與通過冷卻器氣流速度予以提高。

The heat induces by the releasing of the hydraulic power system caused by the friction between its elements and oil is the major influencing parameter on cooling. It contributes more than 50% of heat hence affects the system cooling efficiency more than 50% among the parameters. There is a better way to reduce the system temperature by using a reasonably sized pump. If the air been used as the heat exchange medium, the cooling efficiency can be increased by properly enlarging the cooling surface and air speed.
