ABSTRACT:
An apparatus having a substantially uniformly heated surface is provided for heat exchange purposes, such as use in the printing of textile web materials. The apparatus comprises a cylindrical, rotatable drum including narrowly spaced inner and outer concentric shells defining an annular flow space, and provided with alternating partitions and baffles extending longitudinally within that flow space, thus providing approximately U-shaped flow paths, having entrance and exit legs, for the circulation of a suitable heat-transfer medium, such as hot oil therethrough. The apparatus also includes a centrally disposed concentric tubular conduit, or central feed passage, coaxial with the cylinder or drum, for supply and return of the heat-exchange medium. Means are also provided for supplying the hot heat transfer medium from the central coaxial conduit to each entrance leg of the U-shaped flow paths within the annular flow space, and return means for return of the medium from the exit leg of each U-shaped flow path to the central coaxial conduit. Preferably, the feed means will comprise radially extending feed channels extending outwardly from said central feed passage, for supplying hot heat-transfer medium to an annular feed plenum, which is provided with radial feed distributors, each of which communicate with an entrance aperture in the entrance leg of each U-shaped flow path within the annular flow space. Also, the return means may include an annular return plenum, preferably disposed between the annular feed plenum and the concentric inner shell, the annular return plenum including return orifices communicating with exit apertures in each exit leg of the U-shaped flow paths. The return means also includes radially extending return channels communicating with the annular plenum and with the central feed passage, which is provided with a divider, or strap, in order to separate the feed means from the return means.
