ABSTRACT:
There is disclosed herein an improved header construction for use with fin and tube type heat exchangers which allows for an increased number of radiating fins to be incorporated into a heat exchanger of any predetermined size. This header construction includes a base member having a plurality of tubular projections extending outward from a center interconnecting portion and a pair of oppositely extending substantially parallel spaced apart flange portions extending generally perpendicular to the interconnecting portions. A cover member is also included which has an interconnecting portion with a pair of similarly generally perpendicularly outwardly projecting substantially parallel flange portions which are spaced apart a distance slightly less than the distance between the flange portions provided on the base member so as to be received between and adjacent to respective of the base member flange portions. An optional generally S-shaped clip member is provided which surrounds the lateral sides and end portions of each of these flange members and is brazed thereto to create a multisurface sealing relationship between the flange portions of the base member and cover member. The tubular projections provided on the base member are adapted to be directly connected to the respective tubes of the fin and tube heat exchanger so as to eliminate the need for any transition or intermedite header members thereby enabling this space to be used for additional heat radiating fin portions. Additionally, an optional longitudinally extending baffle and retaining clip assembly is disclosed which enables a single header assembly to provide both inlet and outlet header chambers. Thus, this header construction allows heat exchangers having increased heat radiating capacities to be fabricated within given dimensional sizes.
