International ClassF04B 017/04Foreign Application Priority Data1991-11-15 JPAbstractA liquid coolant circulation control system that minimizes the requisite feed pressure and keeps the flow rate of a liquid coolant constant includes a casing accommodating electronic circuits to be immersed in and cooled by a liquid coolant, a feed pump for feeding the liquid coolant to the casing, and a collecting pump for collecting the liquid coolant from the casing. A first measuring meter, interposed between the feed pump and the casing, measures a flow rate and/or a pressure of the liquid coolant flowing into the casing. A second measuring meter, interposed between the casing and the collecting pump, measures a flow rate and/or a pressure of the liquid coolant flowing out of the casing. A determining section calculates a difference or differences between the two flow rates and/or pressures. The determining section sends this information to a control section. The control section controls the output of one or both pumps, so that the difference or differences remain at a predetermined value. The liquid coolant circulation control system is also provided with a heat exchanger that cools the liquid coolant to a predetermined temperature, and a buffer tank that absorbs an increase or decrease in the volume of the liquid coolant. | |
