▎ 摘　　要

NOVELTY - The device has a shell (1) sleeved on an outer side of a self-rotating mechanism (5) that is coaxially arranged on an outer side of a shaft rod (2). The shaft rod is coaxially arranged with an inner wall of the shell. An end of the shaft rod is connected with an outer end cover (6). Another end of the shaft rod is connected with an inner end cover (7). The self-rotating mechanism is provided with a rotor and multiple blades. A graphene radiating layer is coated on the shell, the blades, the rotor, the inner end cover and an outer wall of the outer end cover. USE - Self-rotating graphite radiating device for direct-drive electro-hydraulic servo actuator. ADVANTAGE - The device is better for system energy saving and radiating device miniaturization, satisfying the electro-hydraulic actuator with high integration, low energy consumption, high heat dissipation rate requirement, increasing the heat transfer area of the device, improving the radiating efficiency of the unit geometric space, which is good for device integration, increasing the air flow near the radiating device, improving the surface heat dissipation coefficient and the heat derived from the graphene can be efficiently radiated out. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the Self-rotating graphene radiating device.
