Abstract
A flame cell of a flame arrestor may include a body of a first material having a first end, a second end, and a plurality of channels formed in the body and extending from the first end to the second end of the body. The flame cell may also include an element of a second material coupled to the body, the second material being different from the first material. The element may be configured to draw heat away from fluid flowing through the plurality of channels.
Claims22
A flame arrestor comprising:
- a housing adapted to be disposed within a fluid passageway, the housing having an inlet, an outlet, and a fluid flow path connecting the inlet and the outlet;
- a flame cell disposed within the fluid flow path of the housing, the flame cell comprising:
- a body of a first material having a first end, a second end, an exterior surface, and an interior core, the interior core having a plurality of channels extending from the first end to the second end of the body, and
- an element of a second material disposed adjacent to the body, the second material being different from the first material, wherein the element is configured to draw heat away from fluid flowing through the plurality of channels;
- and
- wherein a first portion of the element is disposed outside the exterior surface of the body and a second portion of the element is disposed within the interior core of the body.
A flame cell of a flame arrestor, the flame cell comprising:
- a body of a first material having a first end, a second end, an exterior surface, and a plurality of channels formed in the body and extending from the first end to the second end of the body, the exterior surface providing a walled enclosure to the plurality of channels;
- and
- an element of a second material coupled to the body, the second material being different from the first material, wherein the element is configured to draw heat away from fluid flowing through the plurality of channels;
- and
- wherein the element extends outwardly from the exterior surface of the body.
A method of custom manufacturing a flame arrestor, the method including:
- providing a housing having an interior surface and an exterior surface, the exterior surface of the housing being shaped to fit within a fluid passageway;
- forming, using an additive manufacturing technique, a three-dimensional lattice structure by depositing a first material onto the interior surface of the housing in a predetermined pattern, wherein the lattice structure includes a plurality of connected lattice members forming channels extending from a first end to a second end of the three-dimensional lattice structure;
- providing an element of a second material adjacent to the three-dimensional lattice structure, wherein the second material is different than the first material, the element configured to draw heat away from fluid flowing through the plurality of channels.
A method of manufacturing a flame cell of a flame arrestor, the method including:
- forming, using an additive manufacturing technique, a three-dimensional lattice structure of a first material, the three-dimensional lattice structure including a plurality of connected lattice members defining a plurality of channels extending from a first end of the three-dimensional lattice structure to a second end of the three-dimensional lattice structure;
- providing an element extending from the first end of the three-dimensional lattice structure to the second end of the three-dimensional lattice structure, the element being a second material different than the first material;
- and
- coupling the element to the three-dimensional lattice structure, the element configured to draw heat away from fluid flowing through the plurality of channels.
