Abstract

590,623. Tubular heat exchange elements. ARON, E., and POLLARD, E. Jan. 19, 1945, No. 1629. [Class 64 (iii)] [Also in Groups V and XXII] To facilitate the production of a heat exchanger by casting of a structure having a continuous encircling rib with a number of convolutions, these are formed parallel to one another and to a plane normal to the axis of the structure as regards their major portions 74 and each convolution is connected to an adjacent one by a short portion 112 inclined to said plane, these short lengths being adjacent one to another. The sides 113 of the rib are parallel or slightly tapered to facilitate drawing the pattern from the mould and the bottom 114 of the channel 75 may be rounded. The structure may be formed and mounted, as the heating device, on the nozzle of a machine for extruding plastic material.
