  • Publication number: 20120227944
    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.

  • Patent number: 6853555
    Abstract: A low thermal resistance, low cost cooling or heating system and method of constructing the disclosed cooling system. The system may be formed by pressing a tube into a groove in a plate without the use of interface materials or epoxy. The disclosed system includes a plate having a channel adapted to receive a tube, such that the channel holds the tube in place after the tube is press fitted into the channel, thus forming an effective cooling or heating system without the need for addition of epoxy or interface material between the tube and the plate. One or more electronic components to be cooled or heated may be attached to both sides of the disclosed cooling system with equivalent cooling effectiveness. Operation of the disclosed system involves flowing an appropriate fluid through the tube that has been press fitted into the plate.
