Abstract
A flat tube block heat exchanger with a plurality of flat tubes with deformed ends. The deformed ends have broad sides that have been deformed to expose the inner surface of the flat tubes. The exposed inner surfaces of the flat tubes are bonded to the exposed inner surface of an adjacent flat tube. The bonded inner surfaces of the adjacent flat tubes form a fluid barrier with tanks located at opposite ends of the flat tubes.
Claims17
A heat exchanger comprising:
- a pair of tanks spaced opposite each other, and
- a plurality of spaced apart flat tubes to provide flow paths between the tanks;
- each flat tube having opposing ends corresponding to one of the tanks, each end having a first broad side, a second broad side, and two narrow sides, each broad side having an inner surface and an outer surface;
- each first broad side being deformed to expose the inner surface of the first broad side;
- and
- each of the exposed inner surfaces of each first broad side is bonded to the outer surface of any adjacent second broad side to define a fluid barrier with the corresponding tank;
- and
- each of the bonded first and second broad sides are curved to expose the inner surface with a cross-section that is semicircular or semielliptical.
A heat exchanger comprising:
- a pair of tanks spaced opposite each other, and
- a plurality of spaced apart flat tubes to provide flow paths between the tanks;
- each flat tube having opposing ends corresponding to one of the tanks, each end having a first broad side, a second broad side, and two narrow sides, each broad side having an inner surface and an outer surface;
- each first broad side being deformed to expose the inner surface of the first broad side;
- and
- each of the exposed inner surfaces of each first broad side is bonded to the outer surface of any adjacent second broad side to define a fluid barrier with the corresponding tank;
- and
- the each of the narrow sides of each flat tube include two cuts therein, the cuts separating the broad sides of tube ends and defining a tab in each narrow side.
A heat exchanger, comprising:
- a pair of collection tanks spaced opposite each other;
- and
- a plurality of spaced apart flat tubes to provide flow paths between the tanks;
- each flat tube having opposing ends corresponding to one of the tanks, each end having two broad sides and two narrow sides;
- each broad side having an inner surface deformed to expose the inner surface of the broad side;
- each of the exposed inner surfaces of each flat tube being bonded to the exposed inner surface of any adjacent flat tube to define a fluid barrier with the corresponding tank.
A method for manufacturing a heat exchanger, the method comprising the steps of:
- cutting a plurality of flat tube ends to separate each tube end into a pair of broad sides;
- deforming each of the broad sides to expose an inner surface of the broad side;
- abutting the exposed inner surface of each of the broad sides to an exposed inner surface of an adjacent broad side of another tube;
- affixing a tank on the flat tube ends;
- and
- bonding the adjacent broad sides to each other and the flat tube ends to the tanks.
