HEAT EXCHANGER CONSTRUCTION

摘要

HEAT EXCHANGER CONSTRUCTION There is disclosed herein a heat exchanger of the multiple pass counterflow fin and tube type having an improved return bend construction. The return bend construction comprises a base member having a plurality of tapered tubular projections extending outward from one side thereof which define openings extending therethrough. These projections telescopically engage ends of the fluid conducting conduits or tubes. A cover member is provided which is secured to the base member and has a plurality of localized embossments provided thereon which are arranged so as to provide a passageway placing two or more openings in the base plate in mutual fluid communication. The base member also operates as part of a surrounding frame for the heat exchanger and may include mounting points for securing the heat exchanger in the equipment with which it is to be utilized.
