Controlled thin wall thickness of heat exchangers through modeling of additive manufacturing process
Patent number: 10372110Abstract: A method of producing a heat exchanger includes designing the heat exchanger to include a wall with a target thickness. A model is created relating process parameters to geometry of a single track melt pool and relating the single track melt pool geometry to a heat exchanger wall thickness. At least one variable process parameter is defined. The model, heat exchanger wall target thickness, and variable process parameters are used to identify a set of process parameters to produce the heat exchanger wall target thickness. The melt pool geometry is predicted based on the model and process parameters. The heat exchanger wall target thickness is predicted based on the melt pool geometry. The process parameters that will produce the heat exchanger wall target thickness are identified. The additive manufacturing process is controlled based upon the identified set of process parameters to create the heat exchanger wall target thickness.Type: GrantFiled: June 17, 2016Date of Patent: August 6, 2019Assignee: Hamilton Sundstrand CorporationInventors: Vijay Jagdale, Ranadip Acharya, Tahany Ibrahim El-Wardany, Colette O.
