Patent number: 11781819Abstract: A method of forming a cast heat exchanger plate includes forming at least one hot core plate defining internal features of a one piece heat exchanger plate and at least one first set of interlocking features. At least one cold core plate is formed defining external features of the heat exchanger plate and at least one second set of interlocking features. A core assembly is assembled where each hot core plate is directly interlocked to at least one cold core plate. A wax pattern is formed with the core assembly with an external shell formed over the wax pattern. The wax pattern is removed to form a space between the core assembly and the external shell. The space is filled with a molten material. Once the molten material has solidified, the external shell and the core are removed.Type: GrantFiled: September 2, 2022Date of Patent: October 10, 2023Assignee: RAYTHEON TECHNOLOGIES CORPORATIONInventors: Michael A. Disori, Carl R. Verner, Steven J. Bullied, David Donald Chapdelaine

Patent number: 11079181Abstract: In a featured embodiment, a heat exchanger includes a plate including a plate portion having outer walls. A plurality of internal passages extend between end portions. A ratio between an outer wall cross-sectional thickness at one of the end portions and a cross-sectional wall thickness of the outer wall within the plate portion is greater than 2.5 and no more than 10. An inlet manifold is attached to the inlet end. An outlet manifold is attached to the outlet end.Type: GrantFiled: March 5, 2019Date of Patent: August 3, 2021Assignee: Raytheon Technologies CorporationInventors: Michael A. Disori, Alexander Broulidakis, William P. Stillman, David Donald Chapdelaine, Peter E. Gunderson, Dave J. Hyland

Publication number: 20210148638Abstract: A heat exchanger has: an inlet manifold having an inlet port; and an outlet manifold having an outlet port. A first gas flowpath passes from the inlet port to the outlet port. A plurality of plate banks are positioned end-to-end, each plate bank having a plurality of conduits with interiors along respective branches of the first gas flowpath, a second gas flowpath extending across exteriors of the plurality of conduits. One or more docks couple adjacent ends of the plurality of plate banks.Type: ApplicationFiled: November 15, 2019Publication date: May 20, 2021Inventors: Michael A. Disori, William P. Stillman, David J. Hyland, Jeremy A. Styborski, Kyle F. Shaughnessy, Alexander G. Broulidakis, Alan D. Lees, David Donald Chapdelaine

Patent number: 10053992Abstract: A gas turbine engine airfoil includes a body that provides an exterior airfoil surface that extends in a radial direction to a tip. The exterior surface has a leading edge in a forward direction and a trailing edge in an aft direction. The tip includes a squealer pocket that has a recess surface. A cooling passage is arranged in the body. Each of the cooling holes extends from an inlet at the cooling passage to an outlet at the recessed surface. The inlet and outlet are arranged at an angle in an angular direction relative to the recessed surface. The angular direction is toward at least one of the forward and aft directions.Type: GrantFiled: July 2, 2015Date of Patent: August 21, 2018Assignee: United Technologies CorporationInventors: San Quach, Scott D. Lewis, Steven Bruce Gautschi, Christopher King, Christopher Corcoran, David Donald Chapdelaine
