Abstract
An internal cooling passage structure for rotary engine, which includes a rotary engine body, having a front frame, a mid-frame, a rear frame and a rotor, wherein the rotor has cooling passages beneath the rotor triangular apexes, and both front and rear frames respectively have corresponding openings; a rotor, rotating in the mid-frame, having the core cooling passages in full or partial connection with the openings in both front and rear frames in the engine operation; and a guide vane along the opening edge, wherein external air is guided into the rotor core cooling passages by the guide vane which avoids generating heat vortices and helps to increase the cooling air so as to lower the temperature on the rotor and its assemblies.
