Abstract
A hollowed plate for a heat exchanger with fluid flow tubes, formed with holes into which are engaged and tightly fitted the ends of tubes of the exchanger, and being of general bulging or deflected shape, for improving the compressive strength of said hollowed plate, particularly in a radiator for the cooling circuit of a motor vehicle engine.
Claims12
A hollowed tube plate for a heat exchanger having at least a water box and fluid flow tubes, the ends of which are to be engaged and tightly fitted in holes of the tube plate, said tube plate comprising:
- U-shaped edges provided for tight mounting on edges of the water box;
- a central portion of a substantially plane shape in which are formed the holes for the fitting of the tube ends;
- and slanting planes connecting said plane central position with said U-shaped edges, so that the tube plate has a deflected general shape.
