Dual flow heat exchanger header

摘要

An A-coil heat exchanger includes a header for receiving a heat transfer fluid after the fluid has passed through the interior of the heat exchanger. The header is comprised of a main body section and first and second tubular branches depending therefrom. The first tubular branch is in fluid communication with a first coil slab of the heat exchanger by means of a first set of adapter tubes extending between the first tubular section and the first coil slab. The second tubular branch is in fluid communication with a second coil slab of the heat exchanger by means of a second set of adapter tubes extending between the second tubular branch and the second coil slab. Each of the adapter tubes defines a generally straight section of conduit between the corresponding tubular branch and the corresponding coil slab. The header is located with respect to the coil slabs such that when the heat exchanger is positioned in an air stream, the header is substantially isolated from air flowing through the first and second coil slabs.
