DEIONIZED WATER BOILING AND COOLING EQUIPMENT WITH COOLING MEDIUM OPENING AND CLOSING MEANS

摘要

PROBLEM TO BE SOLVED: To provide equipment that is operated well even in below a freezing environment as boiling and cooling equipment that uses deionized water as a cooling medium. SOLUTION: Deionized water boiling and cooling equipment has: an evaporator that receives heat from a cooled body and converts deionized water as a cooling medium from a liquid phase to a gas phase; a gas path that is communicated with the evaporator to guide the deionized water converted from a liquid state to a gas state; a condenser that is communicated with the gas path to receive heat from the deionized water converted to a gas state, thus converting the deionized water from a gas phase to a liquid phase; and a sealed-up cooling system composed of a liquid path that is communicated with the condenser to guide the deionized water converted from a gas phase to a liquid phase back to the evaporator. A cooling medium opening and closing means is provided with either or both of the gas path and liquid path that controls or switches circulation of a cooling medium. COPYRIGHT: (C)2006,JPO&NCIPI
