Abstract
A baffle assembly for a generally elongate heat exchanger tube of the type used in an atmospheric gas-fired heating appliance includes a perforated plate member formed in a V-shaped configuration and adapted to be secured within the heat exchanger tube in the path of combustion gases issuing from a heat exchanger. Ears formed integrally with the plate member engage the rearward end of the heat exchanger tube, and a rod extending forwardly of the plate member engages the forward end of the heat exchanger tube by means of a hook-shaped end portion formed thereon. The plate member is thereby secured within the heat exchanger tube such that combustion gases directed at the forward edge of the plate member are deflected outwardly against the side walls of the heat exchanger tube increasing the heat transfer rate thereto. Combustion gases passing through the perforations of the plate member also serve to heat the plate member to an infra-red energy emitting condition whereby the walls of the heat exchanger tube are further heated by radiant energy. Thus, the baffle assembly provides for substantially enhanced heating efficiency of the appliance.
