Abstract

PURPOSE: A cooling device cools a driven body by exposing protrusions for cooling into an air fluid when a driving member is rotating. CONSTITUTION: Diaphragm panels(9,17) for making the passages of an air fluid(23) are mounted on both sides of a driven body(10). When an engine is started and a shaft rotates a driving member(3), magnetic particles(15) are magnetized if the electricity is flowed through an exciting coil(7). The driven body(10) restrains the rotation of the driving member(3) by being connected to a driving body(3) by using the magnetized particle as a medium. Further, the intensity of the current flowing through the exciting coil(7) controls a braking force. Then, by the braking force, a heat due to a friction among the driving member(3), the magnetic particles(15) and the driven body(10) is generated. A blast panel(16) generated the air fluid(23) integrally connected with the driving member(3). The cooling effect of the driven body(10) is elevated by exposing many large and small exposing protrusions(18,19,20,21) for cooling formed on the diaphragm panels(9,17) into the air fluid(23).
