Abstract
A cooling device to cool an apparatus includes a heat receiver to receive heat from a hot portion of the apparatus using a coolant while contacting the hot portion, a heat releaser to cool the heat-received coolant to release the heat from the hot portion to outside the apparatus, the heat releaser having a variable-speed fan of multiple operation speed modes including an off mode, a coolant circulation system through which the coolant is circulated between the heat receiver and the heat releaser, a variable-speed pump to move the coolant through the coolant circulation system, whose operation speed modes include an off mode and relate to a coolant flow rate of the pump, a temperature sensor to detect a temperature in the hot portion, and a controller to control the operation modes of the fan and the pump in accordance with the temperature detected by the temperature sensor.
