A cooling abnormality detection system for external electronic equipment includes a protection unit, a flowmeter, a water level gauge, a pump operation detector, an abnormal temperature sensor. The flowmeter detects a decrease in flow rate of the liquid coolant supplied from the electronic equipment. The water level gauge is arranged in the coolant tank to detect a decrease in water level of the liquid coolant. The pump operation detector is arranged in a pump to detect an operation of the pump. The abnormal temperature sensor detects an abnormal temperature of the electronic equipment. The protection unit discriminates a cooling abnormality when an abnormal temperature is detected by the temperature sensor during the operation of the pump and discriminates a cooling abnormality when an abnormality is detected by any one of the flow meter, the warer level gauge, and the abnormal temperature sensor during operation of the pump.
