Abstract:
1. A heat exchanger designed to encompass a radial flow heat source, the heat exchanger comprising: a first header having a second header axially spaced from the first header, the second header comprising a bottom circumferential chamber defined by a bottom chamber inner wall and bottom chamber outer wall, having therein a bottom chamber baffle extending from the bottom chamber inner wall to the bottom chamber outer wall, such that when liquid enters the bottom circumferential chamber liquid flow past the bottom chamber baffle is prevented; a first tube sheet and a second tube sheet each having multiple circumferentially spaced inner openings, and multiple circumferentially spaced outer openings, the first tube sheet having a first tube sheet center opening and co-acting with the first header to seal the inner and outer chambers of the first header, and the second tube sheet co-acting with the second header to seal the bottom chamber of the second header; first tubes which extend from the second circumferential chamber to the bottom chamber through the first tube sheet multiple circumferentially spaced inner openings and second tube sheet multiple circumferentially spaced inner openings, the first tubes spaced proximate to the first tube sheet center opening; and second tubes which extend from the first circumferential chamber to the bottom chamber and through the first tube sheet and second tube sheet multiple outer openings, the second tubes spaced from the first tube sheet center opening a greater distance than the first tubes, wherein the bottom chamber baffle is positioned with respect to the first tubes and the second tubes such that when liquid flows from the second tubes into the bottom chamber it allows for the shortest return path through the first tubes to equalize the flow rate through each of the first tubes.
