Abstract
A light-weight, high-strength insulating compressor component formed via additive manufacturing is provided. The component may have at least one interior region comprising a lattice structure that comprises a plurality of repeating cells. A solid surface is disposed over the lattice structure. The interior region comprising the lattice structure minimizes or reduces transmission of at least one of thermal energy, sound, or vibrational energy through the component. Methods of making such compressor components via additive manufacturing processes are also provided.
Claims19
A compressor for a heating or cooling system, the compressor comprising:
- a compression mechanism configured to increase pressure of a refrigerant circulating in the heating or cooling system;
- and
- at least one light-weight, high-strength insulating compressor component comprising a body portion having at least one interior region comprising a metallic lattice structure that comprises a plurality of cells each comprising a node and each formed via additive manufacturing and a surface layer disposed over the metallic lattice structure, wherein the at least one interior region comprising the metallic lattice structure minimizes transmission of at least one of sound or vibrational energy, so that the compressor component is a sound insulating compressor component, wherein the body portion defines at least one sound insulating region that reduces a transmission of sound or a vibrational energy by greater than or equal to about 30% as compared to transmission of the sound or the vibrational energy through a comparative solid body portion.
A scroll compressor for a heating or cooling system, the compressor comprising:
- a compression mechanism configured to increase pressure of a refrigerant circulating in the heating or cooling system, the compression mechanism comprising an orbiting scroll component and a non-orbiting scroll component;
- and
- at least one light-weight, high-strength insulating scroll compressor component comprising a body portion having at least one interior region that comprises a metallic lattice structure comprising a plurality of cells each comprising a node and formed via additive manufacturing and a surface layer comprising a metal disposed over the metallic lattice structure, wherein the at least one interior region comprising the metallic lattice structure minimizes transmission of at least one of sound or vibrational energy, so that the compressor component is a sound insulating scroll compressor component, wherein the body portion defines at least one sound insulating region that reduces a transmission of sound or a vibrational energy by greater than or equal to about 30% as compared to transmission of the sound or the vibrational energy through a comparative solid body portion.
