Abstract
A heat exchanger and method of making a heat exchanger which includes providing a header having openings adapted to receive a plurality of tubes. The tubes are inserted into the header openings, then, substantially uncured fluid sealing material is applied to at least the inner surfaces of the header openings. The inner surfaces of the header openings and the outer surfaces of the tubes are connected by the sealing material. The method further includes curing the sealing material after the tubes are inserted into the header openings. The sealing material thus provides a flexible, bonded, liquid tight, tube-to-header joint.
Claims14
A method of making a heat exchanger comprising the steps of:
- providing a header defining openings having inner surfaces, said header openings adapted to receive a plurality of tubes having outer surfaces;
- applying substantially uncured fluid sealing material to at least said inner surfaces of said header openings;
- curing said sealing material before said tubes are inserted into said header openings, said sealing material providing elastomeric members bonded to said inner surfaces of said header openings adapted to receive said tubes;
- and
- inserting said tubes into said header openings such that said inner surfaces of said header openings and said outer surfaces of said tubes are adjacent to each other and are connected by said elastomeric members to provide a flexible, liquid tight, tube-to-header joint.
A heat exchanger which comprises:
- a header defining openings having inner surfaces, said header openings adapted to receive a plurality of tubes, and said tubes being inserted through said header openings;
- and
- a cured-in-place seal between said tubes and said inner surfaces of said header openings, said seal being bonded to said header, and said seal providing an elastomeric compression sealing fit between said rube and said seal.
A heat exchanger which comprises:
- a header defining openings, said header openings adapted to receive a plurality of tubes, and said tubes being inserted through said header openings;
- and
- a cured-in-place seal between said tubes and said inner surfaces of said header openings, said seal being bonded to said tube, and said seal providing an elastomeric compression sealing fir between said header and said seal.
