<p><P>PROBLEM TO BE SOLVED: To improve cooling performance by an air blowing fan used for a control device in an inverted pendulum type moving body. <P>SOLUTION: The electric equipment cooling system includes an air vent 39A for taking in a traveling wind when a moving body 1 advances, and is provided with the air blowing fan 247 for blowing air in the flow direction of an inflow wind by the traveling wind when advancing, and cools heating of power elements 243a and 244a of substrates 243 and 244 by joining the inflow wind W and fan blowing winds F1 and F2 together. The longitudinal-lateral movement and stopping time are discriminated, and a rotating speed of the air blowing fan is set higher than advancing time in laterally stopping time, and is set further high when retreating. Always excellent cooling performance can be secured by enhancing the rotating speed of the air blowing fan to reduction in the inflow wind except for advancing time. A small air blowing fan being necessary minimum capacity can also be used to a case of setting capacity of the air blowing fan based on the least taking-in quantity of the traveling wind. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
