Abstract

A header for a heat exchanger having a plurality of parallel tubes. The header including an upper wall for permitting the flow of coolant between an inlet/outlet and the header; a bottom wall and an inclined surface extending between inner portions of the bottom wall and the upper wall. The header also includes a flow diverter that includes an inclined spine and a diverting pair of panels extending downwardly. The diverting pair of panels being configured and arranged to facilitate flow of coolant between an inlet/outlet and a pair of outermost tubes and into an inner tube.

Claims (7)

1. A header for a heat exchanger, the heat exchanger having a plurality of parallel tubes having generally rectangular cross sections, the tubes including a pair of outermost tubes and at least one inner tube located between the outermost tubes, the inner tubes having coolant ports and the outermost tubes respectively comprising an outer wall and a parallel inner wall, each of the inner walls having an orifice in the header for access to the outermost tubes, said header comprising:
an upper wall having an end portion, opposing side portions, an inner portion and an inlet/outlet opening for permitting the flow of coolant between an inlet/outlet and said header;
a bottom wall having an end portion, opposing side portions and an inner portion;
an inclined surface extending between the inner portions of said bottom wall and said upper wall, and including the open end(s) of the at least one inner tubes to said header;
a flow diverter comprising a spine inclined from a first position near the upper wall to a second position near said bottom wall, closer to said inclined surface than said first position and having an apex located at the top of said spine near said upper wall;
said flow diverter having diverting first and second panels extending downwardly in opposite radial directions from said apex and on opposite sides of said spine at respective angles towards the respective outermost tubes and respectively ending at the inner portion of said bottom wall, said first panel and said second panel having beveled surfaces inclined towards the at least one inner tube and towards the respective orifices to the respective outermost tubes for facilitating flow of coolant between said inlet/outlet and said pair of outermost tubes and into said at least one inner tube; and side walls extending between the side portions of said upper wall and said bottom wall;
said side walls, upper wall, flow diverter, bottom wall and inclined surface forming a header chamber;
said respective orifice being disposed at least partly over said inclined surface and at least partly beneath said inlet/outlet opening.
2. A header according to claim 1 and further comprising an end wall interconnecting the end portions of said upper wall and of said bottom wall, said end wall being perpendicular to both of said upper wall and said bottom wall.
3. A header according to claim 1 wherein each of said first side wall and said second side wall of said flow diverter extends from said apex and said spine radially at an angle greater than 0° and less than 90° and are inclined at the same angle of inclination towards said plurality of tubes as said spine.
4. A header according to claim 3 wherein said first side wall and said second side wall of said flow diverter extend from said apex and said spine radially at the same angle.
5. A header according to claim 3 wherein said first side wall and said second side wall of said flow diverter extend from said apex and said spine radially at different angles.
6. A heat exchanger having at least one header, said heat exchanger having a plurality of parallel tubes having generally rectangular cross sections, the tubes including a pair of outermost tubes and at least one inner tube located between the outermost tubes, the inner tubes having coolant ports, said header comprising:

a bottom wall having an end portion, opposing side portions and an inner surface;
an inclined surface extending between an intersection with the inner portions of said bottom wall and an intersection with said upper wall, and including the open end(s) of the at least one inner tubes to said header;
a flow diverter disposed in said header comprising a spine extending downwardly at a predetermined angle from an apex located at the top of said spine and having a first panel and a second panel, each of said panels extending downwardly in a radial direction from said apex and said spine at opposite angles and ending at an intersection with the inner surface of said bottom wall, and whereby said first panel and said second panel are additionally angled surfaces being angled towards said plurality of parallel tubes; and side walls extending between the side portions of said upper wall and said bottom wall, said side walls being extensions of the outermost tubes of the heat exchanger, said outermost tubes including an outer wall and an inner wall;
said side walls, upper wall, inclined surface, and bottom wall between the intersections of the flow diverter and bottom wall and the inclined surface and bottom wall, and inclined surface forming a header chamber;
said inner walls of said side walls each having an orifice for permitting the flow of coolant between said header chamber and the respective outermost tube, said respective orifice being disposed at least partly over said inclined surface and at least partly beneath said inlet/outlet opening.
7. A header according to claim 6 and further comprising an end wall interconnecting the end portions of said upper wall and of said bottom wall, said end wall being perpendicular to both of said upper wall and said bottom wall.
