Abstract
A header and coil connection assembly is provided for a heat exchanger. The header is comprised of a first section of a generally half cylindrical structure and a second section of a generally half cylindrical structure. The second section has a plurality of openings each of which receives a heat exchanger tube. The heat exchanger tubes are connected to the second section by welding around the opening.
Claims11
A header for use in a heat exchanger,
- the header comprising
- a generally cylindrical tube structure comprised of two half sections,
- a first section comprised of a half generally cylindrical structure,
- having a first end, a second end, a top edge and a bottom edge, the top edge and the bottom edge running the length of the first section,
- a second section comprised of a half generally cylindrical structure having a first end, a second end, a top edge and a bottom edge, the top edge and the bottom edge running the length of the second section,
- the second section having a plurality of openings between the top edge and the bottom edge, such openings extending through the half generally cylindrical structure,
- the first section being joined to the second section along the respective top edges and bottom edges to form a header.
A method of making a header for use in a heat exchanger comprising the steps of:
- providing a first section comprised of a half generally cylindrical structure having a first end, a second end, a top edge and a bottom edge, the top edge and the bottom edge running the length of the first section,
- providing a second section comprised of a half generally cylindrical structure having a first end, a second end, a top edge and a bottom edge, the top edge and the bottom edge running the length of the second section,
- providing a plurality of openings in the second section half generally cylindrical structure between the top edge and the bottom edge,
- joining at least one heat exchanger tube to one of the openings in the second section half generally cylindrical structure,
- and joining the first section to the second section along the respective top and bottom edges to form a header.
A method of making a header for use in a heat exchanger comprising the steps of:
- providing a first section comprised of an elongated, generally half cylindrical structure having a first end, a second end, a top edge and a bottom edge, the top edge and the bottom edge running the length of the first section,
- providing a second section comprised of an elongated, generally half cylindrical structure having a first end, a second end, a top edge and a bottom edge, the top edge and the bottom edge running the length of the first section,
- providing a plurality of openings in the second section between the top edge and the bottom edge,
- joining at least one heat exchanger tube to one of the openings in the second section by welding around the heat exchanger tube at the opening,
- and joining the first section to the second section by welding along the respective top and bottom edges to form a header.
