To provide a cooler which can detect an abnormality of itself without using information on a heat source which is a cooling object.SOLUTION: A cooler disclosed in this specification comprises: a pump which feeds a refrigerant to a heat source by pressure; a rotation number sensor which measures the number of rotations of the pump; a temperature sensor which measures temperature of the refrigerant; and a controller. The controller outputs a signal for notifying a user of the generation of an abnormality (a step S8) when the number of rotations of the pump deviates from a predetermined allowable rotation number range (a step S2:NO), and a state in which a temperature change rate of the refrigerant exceeds a predetermined change ratio upper limit value (a step S4:NO) continues for a predetermined period (a step S7:YES).SELECTED DRAWING: Figure 2

    【課題】本明細書は、冷却対象である熱源の情報を用いずに自身の異常を検知することのできる冷却器を提供する。【解決手段】本明細書が開示する冷却器は、熱源へ冷媒を圧送するポンプと、ポンプの回転数を計測する回転数センサと、冷媒の温度を計測する温度センサと、コントローラを備える。コントローラは、ポンプの回転数が予め定められた許容回転数範囲外れており(ステップS2:NO)、かつ、冷媒の温度変化率が予め定められた変化率上限値を超えている状態(ステップS4:NO)が予め定められた期間の間継続した場合(ステップS7:YES)、異常発生を通知する信号を出力する(ステップS8)。【選択図】図2
