<p><P>PROBLEM TO BE SOLVED: To provide a cooling device capable of efficiently filling a liquid coolant in a circulation path in a short time. <P>SOLUTION: A cooling device (14) comprises a circulation path (17) in which a liquid coolant flows, and a pump (15) for circulating the liquid coolant along the circulation path. The pump comprises a pump casing (18) provided with a pump chamber (31) in which the liquid coolant flows, and an impeller (35) which is housed in the pump chamber of the pump casing to push out the liquid coolant from the pump chamber to the circulation path. An injection opening (50) is formed at the pump casing. The injection opening is used for injecting the liquid coolant into the pump chamber, and is stopped with a closing member (55) except when injecting. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
