▎ 摘　　要

NOVELTY - The tank has an oil tank body (1) whose top plate is fixed with an oil injection hole. Two oil draining holes are tightly equipped with a fuel tank accessory (5). The top plate of the oil tank body is fixed with an inner cavity that is formed with an oil return port (6) and an oil outlet (7). A driving blade (2) is located in the oil box body and located between the oil return port and a bottom plate of the oil tank body. An outer fan (3) is located at an outer side of the oil tank body that is fixed with a shaft through hole. A central shaft is connected with the driving blade. The outer fan is attached with a graphene heat conducting layer (4). USE - Graphene heat-conducting fan integrated oil return power driven hydraulic oil tank. ADVANTAGE - The tank avoids additional power requirements to drive the fan and reuses oil return energy so as to improve energy saving effect of a hydraulic system. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a graphene heat-conducting fan integrated oil return power driven hydraulic oil tank in partial section.
