Title:

COOLING DEVICE AND ELECTRONIC EQUIPMENT HAVING THE SAME

Document Type and Number:

Japanese Patent JP2005190091

Kind Code:

A

Abstract:

To provide a cooling device avoiding the overheating state of a heat generating matter caused by deterioration in cooling capability by detecting the shortage of the liquid quantity of the coolant of the cooling device, and electronic equipment mounted with the cooling device.

The cooling device for a computer device is configured by arranging a cooler 4 and a heat radiator 5 and a pump 6 and a reserve tank 7 for storing a coolant in a closed cyclic path for circulating the coolant, and making the pump 6 circulate the coolant by the set number of rotations, and making the cooler 4 take heat from a CPU 2 by using the coolant, and making the heat radiator 5 radiate the taken heat. The cooling device is provided with a determination means for determining that operation should be continued when the number of rotation of the pump 6 is not more than the set number of rotations, and for determining that the liquid quantity of the coolant is insufficient when the number of rotations of the pump 6 exceeds the set number of rotations.
