Patent ID: 8727695

Claim:
An apparatus comprising: a first member having a body portion and a flange portion projecting from said body portion and extending along an endless path encircling an axis to define a receiving aperture, wherein a fillet is defined at a junction of said body portion and an inner surface of said flange portion; a second member having a plug portion receivable in said receiving aperture with a first surface operable to abut said body portion and limit movement of said plug portion into said receiving aperture and a second surface slidably engageable with said inner surface of said flange portion to guide movement of said plug portion into said receiving aperture along said axis, wherein a chamfer is defined at a junction of said first and second surfaces such that a gap is defined between said fillet and said chamfer when said plug portion is received in said receiving aperture; and at least one passageway extending at least partially through at least one of said first member and said second member between said gap and an opening spaced from said gap, said at least one passageway operable to receive a heat-transfer fluid to transfer heat relative to said fillet; wherein said at least one passageway further comprises: first and second passageways spaced from one another about said axis, wherein the first passageway is in fluid communication with one side of a cross-section of the gap and the second passageway is in fluid communication with an opposite side of the cross-section of the gap.
