Abstract

Tłumik akustyczny do urządzeń klimatyzacyjnych charakteryzuje się tym, elementy tłumiące stanowi szereg elementów rurowych( 2) o ilości i kształcie przekroju dobranym w zależności od żądanego stopnia tłumienia, usytuowanych równolegle do siebie oraz boku obudowy (1), a każdy element rurowy (2) zawiera przelotowe otwory na swej bocznej powierzchni i pokryty jest welonem (3) stanowiącym bardzo cienką warstwę materiału porowatego, korzystnie o bardzo dużej gęstości, która z kolei otoczona jest powłoką (4) z materiału porowatego o mniejszej gęstości, natomiast wolna przestrzeń pomiędzy elementami rurowymi wypełniona jest materiałem tłumiącym (5) o większej gęstości ale o mniejszej gęstości niż gęstość welonu, przy czym końce elementów rurowych (2) zaopatrzone są w obwodowe wybrzuszenia i zamocowane są trwale w obudowie poprzez uszczelki pierścieniowe z materiału elastyczno-sprężystego.The silencer for air-conditioning devices is characterized by the fact that the damping elements are a series of pipe elements (2) with the number and shape of the cross section selected depending on the desired degree of damping, located parallel to each other and the side of the housing (1), and each pipe element (2) contains through holes on its side surface and is covered with a veil (3) constituting a very thin layer of porous material, preferably with a very high density, which in turn is surrounded by a coating (4) of lower density porous material, while the free space between the tubular elements is filled damping material (5) with a higher density but with a lower density than the thickness of the veil, the ends of the tubular elements (2) are provided with circumferential bulges and are permanently fixed in the housing by ring seals of elastic-elastic material.
