Abstract
A fluid silencer includes: an expansion pipe disposed on a pipe through which a fluid containing noise sources flows and having an accommodation space therein; a viscous fluid received in the accommodation space; a noise introducing member disposed between the pipe and the expansion pipe to seal the accommodation space and allowing the noise sources to be introduced into the accommodation space therethrough; at least one partition member disposed in the accommodation space and dividing the accommodation space in a flow direction of the fluid; multiple baffle members disposed on one surface of the partition member and forming multiple sound absorbing spaces into which the noise sources introduced into the accommodation space are dispersedly introduced; and an elastic member disposed between the partition member and the baffle members and contracted/expanded by the viscous fluid entering/leaving the sound absorbing spaces as the noise sources are introduced into the sound absorbing spaces.
