Abstract
The invention relates to a manifold, of the type comprising a substantially flat plate (20) with holes (22) to accept tubes of a heat exchanger, and turned-up lateral edges (24) extending at an angle to said plate (20) and connected thereto by at least one curved portion in which ribs (52) are formed, the ribs each having a convexity extending substantially in the direction of extension of the lateral edges (24). The plate (20) comprises at least one additional rib (50) between at least some of said holes (22), which ribs each have a convexity extending substantially in the opposite direction to the direction in which the lateral edges (24) extend.
Claims18
A header tank comprising two metal components nested one inside the other and intended to be assembled by brazing, wherein the two metal components are a manifold (18) and a cover (30) to close the manifold (18), the manifold (18), comprising a substantially flat plate (20) with holes (22) to accept tubes (14) of a heat exchanger (10), and turned-up lateral edges (24) extending at an angle to the said plate (20) and connected thereto by at least one curved portion (26) in which a plurality of first ribs (52) are formed, the first ribs (52) each having a convexity extending substantially in the direction of extension of the lateral edges (24), characterized in that the plate (20) comprises at least one second rib (50) between at least some of the holes (22), wherein each at least one second rib (50) has a convexity extending substantially in the opposite direction to the direction in which the lateral edges (24) extend, and wherein the lateral edges (24) include a plurality of third ribs (56) that extend a chosen distance away from the end of the lateral edges (24), wherein the plurality of first ribs (52), the at least one second rib (50), and the plurality of third ribs (56) are distinct from one another, and wherein the plurality of first ribs (52) have a convexity extending opposite a convexity of the at least one second rib (50).
A manifold (18) comprising:
- a substantially flat plate (20) with holes (22) to accept tubes (14) of a heat exchanger (10), and turned-up lateral edges (24) extending at an angle to the plate (20) and connected thereto by at least one curved portion (26) in which a plurality of first ribs (52) are formed, the plurality of first ribs (52) each having a convexity extending substantially in the direction of extension of the lateral edges (24), characterized in that the plate (20) comprises at least one second rib (50) between at least some of the holes (22), wherein each at least one second rib (50) has a convexity extending substantially in the opposite direction to the direction in which the lateral edges (24) extend, wherein the lateral edges (24) include a plurality of third ribs (56) that extend a chosen distance away from the end of these edges (24) and wherein the plurality of third ribs (56) of each lateral edge (24) each have a convexity extending in the direction of the opposite lateral edge (24), and wherein the plurality of first ribs (52) have a convexity extending opposite a convexity of the at least one second rib (50).
A manifold (18) comprising:
- a substantially flat plate (20) with holes (22) to accept tubes (14) of a heat exchanger (10), and turned-up lateral edges (24) extending at an angle to the plate (20) and connected thereto by at least one curved portion (26) in which a plurality of first ribs (52) are formed, the plurality of first ribs (52) each having a convexity extending substantially in the direction of extension of the lateral edges (24), characterized in that the plate (20) comprises at least one second rib (50) between at least some of the holes (22), wherein each at least one second rib (50) has a convexity extending substantially in the opposite direction to the direction in which the lateral edges (24) extend and wherein a region (54) connects each of ribs (50) to each of plurality of first ribs (52), wherein the lateral edges (24) include a plurality of third ribs (56) that extend a chosen distance away from the end of these edges (24), and wherein the plurality of first ribs (52) have a convexity extending opposite a convexity of the at least one second rib (50).
