Abstract
Low efficiency in an evaporator for a refrigerant may be increased by providing the evaporator with at least two passes (10, 12) defined by two rows of tubes (20) and four elongated header passages (24, 26, 28, 30) with the header passages (24, 26) being in fluid communication with the tubes (20) in the pass (10) and the header passages (28, 30) being in fluid communication with the tubes (20) in the pass (12). The pass (10) is downstream from the pass (12) and includes an inlet (32) to the header passage (24) intermediate the ends thereof. An outlet (34) is located in the header passage (28) for the pass (12) and intermediate the ends thereof. At least one fluid passage (36) extends between the headers (26, 30) intermediate the ends thereof
Claims7
In a heat exchanger having at least one laminated header including a header plate having a header passage therein, a cover plate abutting said header plate on one side thereof and sealed thereto, and a tube plate on the other side of said header plate and sealed thereto, said tube plate having a plurality of tube receiving openings aligned with and in fluid communication with said header passage, and a plurality of tubes having open ends, the ends of said tubes being received in said openings in sealed relation therewith, the improvement comprising stop means at the interface of said tube plate and said header plate including stop surfaces engageable with tubes in each of said openings for preventing the associated tube from extending through its associated opening in the tube plate into said header passage.
In a heat exchanger having at least one laminated header including a header plate at least in part defining a header passage and a tube plate sealed to the header plate and having a plurality of tube receiving openings aligned with and in fluid communication with the header passage, and a plurality of tubes having open ends, the ends of the tubes being received in the openings in sealed relation therewith, the improvement comprising stop means at the interface of said tube plate and said header plate including stop surfaces engagable with tubes in each of said openings for preventing the associated tube from extending through its associated opening in the tube plate to enter into said header passage, said stop surfaces being defined by a stop plate interposed between said header plate and said tube plate.
In a heat exchanger having at least one laminated header including a header plate at least in part defining a header passage and a tube plate sealed to the header plate and having a plurality of tube receiving openings aligned with and in fluid communication with the header passage, and a plurality of tubes having open ends, the ends of the tubes being received in the openings in sealed relation therewith, the improvement comprising stop means at the interface of said tube plate and said header plate including stop surface engagable with tubes in each of said openings for preventing the associated tube from extending through its associated opening in the tube plate to enter into said header passage, and a cover plate abutted to said header plate on the side thereof opposite said tube plate, said cover plate being sealed to said header plate.
