Liquid cooling device and electronic equipment provided with the same

摘要

A liquid cooling device according to the invention is based upon a liquid cooling device for a computer in which a cooler, a radiator, a pump and a reserve tank for reserving a refrigerant are provided to a closed circulating passage for circulating the refrigerant, the pump operating at a predetermined revolution circulates the refrigerant, the cooler removes heat from CPU using the refrigerant and the radiator radiates the removed heat, and is mainly characterized in that judgment means that judges that the operation is to be continued in case the revolution of the pump is equal to or smaller than the set revolution and judges that the quantity of the refrigerant is insufficient in case the revolution of the pump exceeds the set revolution is provided.
