Manifold bending support
View Patent ↗A bending support having a planar bracing member with a length (L) that is substantially equal to that of the inner diameter (I.D.) of the manifold header that the bending support is ultimately inserted in. Extending perpendicularly from a surface of the bracing member is a pair of bracketing members. The pair of bracketing member and the portion of the planar bracing member therebetween defines a refrigerant conduit clip. The interior surface of the refrigerant conduit clip includes a skived pattern defining a plurality of teeth or protrusions that aids in the attachment of the refrigerant conduit clip onto an internal refrigerant conduit. An aperture located on the planar bracing member between the pair of bracketing member provides an unobstructed path for refrigerant flow to the refrigerant conduit.
1. For use with a cylindrical heat exchanger manifold header having an interior surface with a predetermined inner surface diameter, and with a cylindrical refrigerant conduit of smaller diameter to be supported within said manifold, a bending support configured to be inserted into said manifold header, comprising:
a planar bracing member having two opposite facing member edge surfaces, the bracing member includes a length substantially equal to said manifold inner surface such that said member edge surfaces abut an interior surface of the manifold header to provide an interference fit;
a pair of bracketing members extending perpendicularly from one side of said bracing member and spaced apart substantially by the diameter of said refrigerant conduit so as to tightly grip the outside thereof and terminating in distal ends that abut said manifold interior surface when said bracing member edge surfaces abut said interior surface,
wherein said bending support supports the interior of said manifold surface and supports said refrigerant conduit in position when said manifold and supported conduit are bent in a radius while the plane of said bracing member is perpendicular to the axis about which said radius is bent.
2. The bending support of claim 1 , further comprising a pair of bracketing members extending from a surface of said bracing member.
3. The bending support of claim 2 , wherein said pair of bracketing members and a portion of said bracing member between said pair of bracketing members are configured such that such that said pair of bracketing members cooperates with said portion of said bracing member between said pair of bracketing members to securely clip onto an outer diameter of a refrigerant conduit.
4. The bending support of claim 3 , wherein each of said pair bracketing members includes an interior surface oriented toward the other, and wherein said interior surface includes a skived portion defining a plurality of saw tooth surfaces.
5. The bending support of claim 4 , wherein each of said pair of bracketing members includes a bracketing member end, and wherein said bracketing members includes a length such that said bracketing member ends abut the interior surface of the manifold header to provide an interference fit.
6. The bending support of claim 5 , wherein said bracing member between said pair of bracketing members defines an aperture.
7. The bending support of claim 5 , wherein said edges of said bracing member and ends of said bracketing member are contoured to the interior surface of the manifold header.
