Publication number: 20160146551Abstract: A heat exchanger assembly comprises at least two heat exchanger cores arranged in parallel flow, each heat exchanger core including a plurality of tubes, fins between the tubes and opposing headers sealingly attached at each end of the tubes. A common tank is positioned between the at least two heat exchanger cores and connected to a header at one end of each heat exchanger core, and separate tanks are connected to a header at the other end of each of the at least two heat exchanger cores. The separate tanks may be inlet tanks for fluid passing into the heat exchanger assembly and the common tank may be an outlet tank for fluid passing out of the heat exchanger assembly, or the flow path may be reversed, with the common tank being an inlet tank and the separate tanks being outlet tanks.Type: ApplicationFiled: September 4, 2015Publication date: May 26, 2016Inventor: John A.

Publication number: 20160084591Abstract: A tube-to-header sealing system for a heat exchanger comprises a pair of mating header plates, each header plate having a wall with a plurality of openings therein and including a continuous depression along the circumference of each header plate opening which forms one-half of an O-ring groove. Each of a plurality of O-rings is positioned in each O-ring groove and the header plates are secured together such that the header plate plurality of openings are aligned and trap each of the plurality of O-rings in O-ring grooves. A plurality of spaced-apart tubes each having a tube end secured in an opening in the wall of the header to form a tube-to-header joint are expanded outwardly to provide sufficient O-ring deformation to obtain a seal. In service, the resiliency of the O-ring seal allows for expansion and contraction of the tubes without the build-up of high stresses at the tube-to-header joint.Type: ApplicationFiled: September 3, 2015Publication date: March 24, 2016Inventors: Richard F. Crook, John A. Kolb

Publication number: 20150300742Abstract: A heat exchanger tube has a tube end having two extended portions substantially opposite the other around the periphery of the tube end, and two shortened portions, each positioned between the two extended portions and substantially opposite the other around the periphery of the tube end. The tube end may be formed by removing opposite portions of the tube by cutting a disc-shaped portion with a generally smoothly curving periphery along a major portion of the width of the tube. Each tube is oriented within an opening in the header wall of a heat exchanger assembly having a header portion integral with a tank portion, such that the tube end two extended portions are oriented substantially perpendicular to the direction of fluid flow within the header and the tube end two shorter portions are oriented substantially in the direction of fluid flow in order to reduce interference with fluid flow.Type: ApplicationFiled: September 10, 2014Publication date: October 22, 2015Inventor: John A.
