The invention provides a silicon oil fan clutch and relates to an engine cooling device. Each blade comprises an upper blade body and a lower blade body, wherein the upper blade body is provided witha containing groove, and the bottom of the containing groove is provided with an iron bar; the lower blade body is provided with an insertion plate matched with the containing groove; the top of the insertion plate is provided with an electromagnet array matched with the iron bar; the upper blade body and the lower blade body move mutually under the action of the iron bar and the electromagnet array; an elastic rubber sheet is attached to the blade. Compared with the prior art, the silicon oil fan clutch has the beneficial effects that the fan blades of a fan arranged on the silicon oil fan clutch are spread under the action of centrifugal force during low-speed operating of the silicon oil fan clutch operates so as to increase the air supply rate and enhance the heat dissipation efficiency; the fan blades are ret
