ABSTRACT:
According to this invention, a liquid coolant circulating system includes a cooling tank, a discharge pump, a recovery pump, a heat exchanger, a detector, and a controller. The cooling tank is filled with a liquid coolant for immersing an object to be cooled. The discharge pump is arranged on an inlet side of the cooling tank and supplies a liquid coolant to the cooling tank at a predetermined flow rate. The recovery pump is arranged on an outlet side of the cooling tank and recovers a liquid coolant from the cooling tank. The heat exchanger is arranged on an outlet side of the recovery pump and cools a heated liquid coolant to a predetermined temperature and supplies a cooled liquid coolant to the discharge pump. The detector detects a value related to a pressure in the cooling tank. The controller controls the ability of the recovery pump in response to a detection signal from the detector.
