Abstract
A temperature predicting unit predicts the temperature of an electronic device after a predetermined period, and the speed of temperature variation from the operating state of the load. Based on the results of prediction by the temperature predicting unit, a selection unit instructs either one or both of a nozzle control unit and an electric fan control unit to exercise control. According to a control signal from the selection unit, the nozzle control unit transmits a control signal to a nozzle unit to drive a jet cooling apparatus. According to a control signal from the selection unit, the electric fan control unit transmits a control signal to an electric fan unit to drive an electric fan. The selection unit selects the electric fan when the predicted speed of temperature variation exceeds a predetermined threshold, and selects the jet cooling apparatus when the predetermined thresholds is not exceeded.
