Abstract

PURPOSE: To increase a removal amount of heat flux from a heat exchange surface also simplify a structure, by providing a means rotating a liquid cooling material at an almost equal absolute angular speed it the same direction to a target in a rotating anode assembly unit. CONSTITUTION: Heat generated by an energy beam 43 fitting a focal point track 47 is transmitted to an internal heat transfer surface 22. In the heat transfer surface 22, generally) by boiling a cooling material placed in a turbulent condition, heat is removed. The cooling material, by a centrifugal force flow pump blade 44, is accelerated both in a radial direction 48 and a peripheral direction 50. First centrifugal force by a cooling material tangential speed 48 relating to an anode surface 22 gives a pressure gradient having a vertical component relating to the heat transfer surface 22, in this way, a nuclear bubble is quickly removed by stem conveyance in the radial direction. Also second centrifugal force by an absolute angular speed 50 of the liquid cooling material gives a pressure gradient having a vertical component relating to the heat exchange surface 22, also this gradient quickly removes a nuclear bubble by steam conveyance in the radial direction, heat transmission is improved.
