<p><P>PROBLEM TO BE SOLVED: To provide a cooling system which cools a heating component by circulating a cooling liquid by a fluid pump, wherein the fluid pump need not be located separately from a heat receiving portion and thereby space can be saved, and even if the fluid pump gets out of order, the heating component can be kept cooled. <P>SOLUTION: A casing cover 16 of a casing 10 of the built-in motor fluid pump 8 is formed of a good thermal conductor such as aluminum. The casing cover 16 is in contact with the heating component 5, and the heating component 5 is cooled by the cooling liquid flowing inside the casing 10. Even if either one of the plurality of fluid pumps 8 gets out of order, the cooling liquid sent out from the other fluid pumps 8 rotates the impeller 12 of the faulty fluid pump 8, so the faulty fluid pump 8 cools the heating component 5 nearly normally, too. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
