Abstract:

A heat exchange unit for a heat exchanger assembly is provided for use in a cooling system of a CT imaging system having a gantry frame with an annular interior region. The heat exchange unit is formed of a plurality of tubes bent at discrete locations to divide the tubes into straight leg sections to fit within an arcuate portion of the gantry frame's annular region. The bent tubes are maintained between a pair of tube sheets in an array with the straight leg sections parallel and the bends generally radially aligned. The tubes are orthogonally joined to the tube sheets, and the faying surfaces are flat and parallel, leading to a dependable joint. The heat exchanger assembly includes mounting brackets with mounting fixtures axially aligned with the gantry frame, to reduce stress on the fasteners and the mounting brackets.
