<p>A liquid coolant circulating system includes a discharge pump (103), a cooling tank (107), a recovery pump (108), a heat exchanger (106), a detector (109), and a controller (111). The cooling tank (107) is filled with liquid coolant for immersing an object (105) to be cooled. The discharge pump (103) is on the inlet side of the cooling tank, and supplies liquid coolant to the cooling tank at a predetermined flow rate. The recovery pump (108) is on the outlet side of the cooling tank, and recovers liquid coolant from the cooling tank. The heat exchanger (106) is on the outlet side of the recovery pump, and cools heated liquid coolant to a predetermined temperature and supplies cooled liquid coolant to the discharge pump, e.g. via a buffer tank (101). The detector (109) detects a value related to a pressure in the cooling tank. The detected value may, e.g. be the pressure in the cooling tank, the level in the buffer tank or in a buffer tank between the cooling tank and the recovery pump, or the flow rate or the pressure at the input and/or outlet of the cooling tank, or combinations thereof. The controller (111) controls the recovery pump in response to a signal from the detector. <IMAGE></p> |
