Abstract
A heat exchanger of the type characterized by a plurality of heat exchanger tubes separated by cooling fins. The ends of the tubes being inserted into a leadless header plate and thereafter brazed thereto. The overall depth of the heat exchanger being approximately equal to the width of the heat exchanger tube plus twice the thickness of the material of the header plate. Heat exchange tube ends being inserted into slots formed in the header plate by use of an alignment tool.
Claims10
A leadless header plate comprising:
- a generally flat base portion defining a plurality of slots therein
- and legs on either side of and running the length of the base portion, said base portion and legs being integrally formed and forming a generally flattened U-shaped cross-section, each of said slots having a length equal to the distance between said legs.
A heat exchanger comprising:
- a plurality of tubes in spaced, side-by-side relationship;
- cooling fins between said tubes and attached thereto;
- a header plate at each end of said plurality of tubes, said header plates including a base portion having a width and legs integral to each side of the base portion and running the length of said base portion, said plate having a generally U-shaped cross section, said base portion defining a plurality of slots having a length equal to the width of the base portion;
- means for securing said tubes to said header plates;
- and
- end plates secured to the end of said header plates in parallel relationship with said tubes;
- manifold means attached to each of said header plates and forming a fluid tight chamber therebetween for collecting and dispersing fluid to said plurality of tubes.
