PURPOSE:To reduce the number of components while improving the cooling efficiency, by providing heat pipes so as to extend through the inside of bellows having a flange secured to one end thereof. CONSTITUTION:Each of heat pipes 13-1 which are long enough to reach a liquid path 12b is arranged vertically to a heat conducting fitting 13-2 so as to seal a cooling medium. A cooling assembly 13 in which the fitting 13-2 is fixed closely to the end face of a bellows 13-3 is secured to each of apertures 12a in a body 12. When cooling liquid is pressure-fed through a pipe 4-1 of the body 12, the cooling liquid flows through the liquid path 12b as indicated by the two-dot chain line and strikes against the tip ends of the pipes 13-1 to cool the fittings 13-2 heated by the LSi's 1-1. In this manner, the number of components can be reduced while improving the cooling efficiency.
