Abstract: PROBLEM TO BE SOLVED: To keep uniform temperature inside a computer room by judging whether temperature obtained by simulation is within a specific temperature range or not, and by controlling at least one of wind directions of a fan for covering a position at a temperature that does not exist within the specific temperature range. SOLUTION: Based on temperature, the amount of the wind of a fan, and a wind direction, simulation is carried out, and temperature distribution is obtained. Under the control of a local PC 70, a circuit 76 for controlling the amount of wind controls the speed of a specified fan, and the amount of wind, namely, the force of wind. A circuit 78 for controlling an air conditioner controls the air conditioner according to the state of temperature. For example, when temperature inside a computer room is lower than a specific temperature range, the air conditioner is temporally stopped, or the air conditioner is operated by high power when cooling effect by the fan is low. A circuit 80 for controlling a stator position selectively drives the coil winding of the stator of the specified fan, and controls the wind direction of the fan under the control of the local PC 70.

Abstract: PROBLEM TO BE SOLVED: To enable mounting of an MPU having high performance by improving cooling effect of a notebook personal computer. SOLUTION: A cooling device 11 for a computer is constituted by a housing 14 constituted differently from a notebook personal computer 12, a heat pipe 18 for absorbing heat generated in an MPU 16 which is a heat generating element in the personal computer 12 and for allowing the heat to move into the housing 14, and a heat dissipating means 20 for dissipating the heat moved into the housing 14 to the outside of the housing 14.
