Application: Valve heating arrangement (Patent ID: US20240102580A1)
The patent filed by Raytheon Technologies Corp. describes a heating arrangement for a valve, where a thermally conductive heating wire is embedded within the valve body. This heating wire can generate heat when electric power is applied to it. The valve body is formed using additive manufacturing, with the heating wire embedded within it. The method of manufacture involves forming the valve body structure using additive manufacturing, defining a channel within the valve body, and locating the heating wire in the channel during manufacturing to generate heat in the valve body.
The claims of the patent further detail the specifics of the heating arrangement and valve body, including the use of a non-circular cross-section for the heating wire, such as splined or X-shaped. The valve body may have a filler material around the heating wire, which is thermally conductive and electrically insulative, such as epoxy resin. The method of forming the valve body includes securing the heating wire in position with support elements and using a filler material to secure the heating wire in the channel. Additionally, after additive manufacturing, the support elements can be machined away. Overall, the patent focuses on an innovative heating arrangement for valves, particularly in the context of additive manufacturing processes.
