Abstract
In the present disclosure is proposed a novel sound attenuating element for, at least in part, providing adequate or preferably improved sound attenuating properties without excessively impeding flow while being susceptible to automated or machine assisted manufacturing or for providing the public with a useful alternative. The novel sound attenuating element is formed at least in part by an assembly of a plurality of components which are successively connected to each other, which each exhibit a curved shape, and which form at least one non-planar ruled surface when assembled.
Claims20
A sound attenuating element, which is formed at least in part by an assembly of a plurality of components, which:
- are successively connected to each other along a first axis,
- each exhibit a curved shape, and which
- form at least one non-planar ruled surface when assembled,
- wherein:
- each of the components exhibits an elongated shape such that the dimension of elongation extends perpendicularly to the first axis, and wherein
- every second component in the assembly extends in a non-straight angle, e.g. a right angle, in respect to the successive component.
An enclosure for a sound attenuator, comprising:
- several spiral guides, which are configured to receive a plurality of components in a successively layered fashion so as to create at least one non-planar ruled surface for contacting a gaseous current,
- a first set of two mutually opposing guides each configured to receive a respective opposing end of an elongated component to extend between the guides, and
- a second set of such mutually opposing guides,
- wherein the two sets of opposing guides are angularly offset from each other so as to receive cross-wise subassemblies of two components.
A sound attenuator, comprising:
- the enclosure, which comprises:
- several spiral guides, which are configured to receive a plurality of components in a successively layered fashion so as to create at least one non-planar ruled surface for contacting a gaseous current,
- a first set of two mutually opposing guides each configured to receive a respective opposing end of an elongated component to extend between the guides, and
- a second set of such mutually opposing guides,
- wherein the two sets of opposing guides are angularly offset from each other so as to receive cross-wise subassemblies of two components, and
- a sound attenuating element installed into the enclosures, which sound attenuating element is formed at least in part by an assembly of a plurality of components, which:
- are successively connected to each other along a first axis,
- each exhibit a curved shape, and which
- form at least one non-planar ruled surface when assembled,
- wherein:
- each of the components exhibits an elongated shape such that the dimension of elongation extends perpendicularly to the first axis and wherein
- every second component in the assembly extends in a non-straight angle, e.g. a right angle, in respect to the successive component.
A method of producing a sound attenuator comprising:
- providing an enclosure, which comprises:
- several spiral guides, which are configured to receive a plurality of components in a successively layered fashion so as to create at least one non-planar ruled surface for contacting a gaseous current,
- a first set of two mutually opposing guides each configured to receive a respective opposing end of an elongated component to extend between the guides, and
- a second set of such mutually opposing guides,
- wherein the two sets of opposing guides are angularly offset from each other so as to receive cross-wise subassemblies of two components,
- providing a sound attenuating element formed at least in part by an assembly of a plurality of components, which:
- are successively connected to each other along a first axis,
- each exhibit a curved shape, and which
- form at least one non-planar ruled surface when assembled,
- wherein:
- each of the components exhibits an elongated shape such that the dimension of elongation extends perpendicularly to the first axis and wherein
- every second component in the assembly extends in a non-straight angle, e.g. a right angle, in respect to the successive component, and
- installing the sound attenuating element into the guide of the enclosure so as to form a non-planar ruled surface for contacting gaseous currents.
