Abstract
A clamping device on heat exchangers that will mechanically force mating parts together to prevent fluid leakage. The clamping device comprises one or more mechanically formed clips or clamps sprung around the rims of mating parts with sufficient force to prevent the faying surfaces from separating during normal use. Gaskets or sealing compounds may be present between the surfaces.
Claims3
A retaining clip for use in securing a tank and a header plate of a heat exchanger together in a fluid tight relationship, the tank and the header plate each having a peripheral flange receiving a resilient sealing gasket therebetween, the header plate flange having a depending portion and an outwardly and upwardly inclined portion defining a channel receiving said gasket, the retaining clip comprising a base portion joining a pair of oppositely disposed substantially parallel walls completely formed prior to assembly, said one wall extending behind the depending flange portion of said header plate flange, and the opposite wall being positioned beyond said peripheral flanges and terminating in an inwardly inclined flange engaging the tank flange to compress the sealing gasket, the inclined clip flange initially contacting said tank flange and the clip is rotated to snap under said header plate flange.
