The invention aims to provide a guided gas anti-icing device. The guided gas anti-icing device comprises a flute-shaped tube assembly arranged in an anti-icing cavity defined by the anti-icing surface, and the flute-shaped tube assembly comprises an inner tube and an outer tube; the inner wall of the outer tube and the outer wall of inner tube are slidably attached in a sealed mode; the outer tubeis provided with a first exhaust port, and the inner tube is provided with a second exhaust port; the outer tube is further provided with a first gas inlet, and the inner tube is further provided with a second gas inlet; the flute-shaped tube assembly further comprises a throttling plate and an elastic part, the throttling plate is located on one side of the second gas inlet, and one end of the throttling plate is fixed into the inner tube so as to decrease the flow channel area of the inner tube; after entering the inner tube, guided gas passes through a throttling opening to flow from the front side of the throttling plate to the rear side of the throttling plate, and the guided gas is throttled so that the throttling plate can apply driving force to the inner tube; and the elastic partis used for providing elastic force counteracting the driving force, thus the inner tube can be kept balanced at different axial positions inside the outer tube, and the first exhaust port and the second exhaust port have different communicating combinations.
