<p><P>PROBLEM TO BE SOLVED: To provide a compact and economical device exhibiting enhanced cooling efficiency. <P>SOLUTION: In a heat radiation circulation main loop 10, a liquid refrigerant of a refrigerant tank 14 is pressurized and fed by a main pump 16 and is made to flow to a cooling plate 18 for cooling electronic elements, and then the heat is radiated by a main heat exchanger 20, and the liquid refrigerant is returned to the refrigerant tank 14. In a heat radiation circulation sub loop 12, the liquid refrigerant of the refrigerant tank 14 is pressurized and fed by a sub pump 22, and the heat is radiated by a sub heat exchanger 24, and then the liquid refrigerant is returned to the refrigerant tank 14. A controller 26 controls a supply flow rate from the main pump 16 and the sub pump 22 as the need arises. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
