Abstract
A clamshell heat exchanger includes a first clamshell half and a second clamshell half. The first and second clamshell halves each include a through-hole therein. The first and second clamshell halves form a passageway, with a seal region located between portions of the passageway. A fastener is located within the first and second through-holes within the seal region. The fastener is configured to rigidly join the first clamshell half to the second clamshell half while allowing relative lateral motion between said first and said second clamshell halves.
Claims17
A clamshell heat exchanger, comprising:
- a first clamshell half having a first through-hole therein;
- a second clamshell half having a second through-hole therein;
- a passageway formed by first and second clamshells, with a seal region located between portions of said passageway, and
- a fastener located within said first and second through-holes within said seal region, said fastener configured to rigidly join said first clamshell half to said second clamshell half while allowing relative lateral motion between said first and said second clamshell halves, wherein said fastener is located adjacent an interference pattern located within said seal region.
A method of manufacturing a clamshell heat exchanger, comprising:
- providing a first clamshell half having a first through-hole therein;
- providing a second clamshell half having a second through-hole therein, said second clamshell half being configured to form a passageway when joined to said first clamshell half, a seal region being located between portions of said passageway;
- and
- joining said first clamshell half to said second clamshell half;
- and
- installing a fastener within said first and second through-holes within said seal region, said fastener configured to rigidly join said first clamshell half to said second clamshell half while allowing relative lateral motion between said first and said second clamshell halves, wherein said fastener is located adjacent an interference pattern located within said seal region.
A furnace, comprising:
- a cabinet;
- a blower configured to move air through said cabinet;
- and
- a heat exchanger located within said cabinet and configured to transfer heat from a burned fuel to said air, said heat exchanger including:
- a first clamshell half having a first through-hole therein;
- a second clamshell half having a second through-hole therein;
- a passageway formed by first and second clamshells, with a seal region located between portions of said passageway;
- and
- a fastener located within said first and second through-holes within said seal region, said fastener configured to rigidly join said first clamshell half to said second clamshell half while allowing relative lateral motion between said first and said second clamshell halves, wherein said fastener is located adjacent an interference pattern located within said seal region.
