Abstract
Heat exchanger core comprising flat plate fluid U flows tubes stacked on one another and operatively connected to one another by discrete fluid supply and suction lines. These lines extending through side-by-side tank portions of the tubes to improve structural integrity of the core and respectively have fluid feed and exhaust openings communicating with the tanks and sized to provide even distribution of the heat exchanger fluid to the tubes. With the supply and suction lines, evenly distributing the heat exchanger fluid, tank size and capacity is optimized and the requirement for large capacity deep draw tanks of prior constructions is eliminated.
Claims7
A heat exchanger having a plurality of flattened fluid flow tubes operatively mounted adjacent one another to provide passage for volatile heat exchanger fluid therethrough, each of said tubes having a leading edge, a trailing edge and a lower end, said edges bounding flattened side portions that are laterally spaced from one another, a divider rib extending in each of said tubes to a terminal end therein to define separate first and second side flow sections in each of said tubes and a crossover section at the lower end thereof for transmitting said heat exchanger fluid from said first side flow section to said second side flow section, and an inlet line extending into each of said tubes for feeding heat exchanger fluid into each of said first side flow section of each of said tubes and an outlet line extending in each of said tubes for exhausting heat exchanger fluid from said second side flow section of each of said tubes.
A heat exchanger having a plurality of flattened fluid flow tubes operatively arranged adjacent to one another to provide passage for volatile heat exchanger fluid therethrough, a connection for interconnecting said tubes so that air can externally pass between said tubes, each of said tubes having a leading edge and a trailing edge and flattened side portions that are laterally spaced from one another, divider rib means in each of said tubes extending between the walls of said tubes to a terminal end therein to define first and second discreet side flow sections in each of said tubes and a crossover section for transmitting said volatile heat exchanger fluid from one side flow section to the other side flow section, an elongated inlet line and an elongated outlet line extending into each of said tubes of said heat exchanger and out of each of said tubes, said lines having fluid flow openings therein for transmitting heat exchanger fluid into a first side flow section of each of said tubes and for transmitting fluid from said second side flow section each of said tubes.
