Abstract

The present invention relates to a silencer device for a fluid line which comprises a resonator arrangement which comprises a first resonator tube comprising a first resonator chamber designed for a λ/4 damping of at least one sound wavelength, wherein the first resonator tube comprises a first longitudinal direction, two end walls facing each other in the first longitudinal direction and a first side wall extending between the end walls, and wherein the first resonator chamber is formed between the first side wall and the end walls of the first resonator tube. The resonator arrangement further comprises a second resonator tube comprising a second resonator chamber designed for a λ/4 damping of at least one sound wavelength, wherein the second resonator tube comprises a second longitudinal direction, two end walls facing each other in the second longitudinal direction and a second side wall extending between the end walls, and wherein the second resonator chamber is formed between the second side wall and the end walls of the second resonator tube. The invention further relates to a heating device comprising such a silencer device.
