Abstract

631,300. Heat-exchangers. MORRIS MOTORS, Ltd., and YOUNG, J. A. Nov. 6, 1947, No. 29581 [Class 64(iii)] Relates to heat-exchangers of brazed construction, particularly those designed for aircraft, and consists in reinforcing the exposed edge portions of the airways by coating them with metal to increase their thickness relative to the main wall portion of the airways. The coating may be applied by dipping in molten metal, by spraying or preferably by electro-deposition. The heat-exchanger shown comprises flat tubes 12 passing through gill-plates 13, and connected to tube-plates 14 (one only shown) at the top and bottom of the matrix. The plates 13 are spaced apart to form air-passages and each plate is thickened at the air. entry and exit faces of the matrix by submerging the matrix in an electro-plating bath between two anodes, the matrix being the cathode. The edges to be thickened are placed facing the anodes so that deposition is principally on these edges 20. Alternatively the front face of the matrix is immersed in the electrotype to the required depth of reinforcement above a horizontal plate constituting the anode and when a sufficient coating has been formed the matrix is reversed and the process repeated.
