Publication number: 20180283804Abstract: A component that generates or requires heat includes a heat exchanger integrated with the component. The component includes a component housing holding functional parts of the component, and the heat exchanger has a heat exchanger housing formed integrally with the component housing. There is a first fluid circuit in which a first fluid flows through the component in a heat exchange relationship with the functional parts, into the heat exchanger via a first fluid inlet, through the heat exchanger, out of the heat exchanger via a first fluid outlet, and back to the functional parts of the component. The heat exchanger has a second fluid inlet and a second fluid outlet for connection into a second fluid circuit in which a second fluid flows from outside of the component into the component.Type: ApplicationFiled: March 30, 2018Publication date: October 4, 2018Inventors: Berwyn Owain POLLARD, Paul A. PHILLIPS

Patent number: 9260191Abstract: A heat exchanger apparatus is disposed within a first pathway along which a first fluid flows. The heat exchanger apparatus includes a component disposed in the first pathway and the component includes heat transfer surfaces. Each heat transfer surface includes a central body, an outer body surrounding the central body and intermediate bodies extending between the central body and the outer body. The heat transfer surfaces are arranged together such that the central bodies, the outer bodies and the intermediate bodies of each heat transfer surface form at least one or more second pathways along which a second fluid flows and such that the outer bodies of each heat transfer surface form a component surface disposed to contact the first and second fluids.Type: GrantFiled: August 26, 2011Date of Patent: February 16, 2016Assignee: HS MARSTON AEROSPACE LTD.Inventors: Berwyn Owain Pollard, David Russell Scott
