Abstract
A slide guide 22 for a tube-type heat exchanger has a tubular geometry and comprises saddle 28 and slots 26 interposed one each between fingers 24. Saddle 28 positions slide guide 22 within tube support sheet port 30 while fingers 24 are biased so as to conform to the ovality of tube 12 and dissipate dynamic loads across a relatively large tube surface area.
Claims3
A tube-type heat exchanger, wherein the improvement comprises a slide guide interposed between the heat exchanger tube and the tube support sheet for preventing abrasion and high localized stress on heat exchanger tubes and wherein said slide guide comprises:
- a plurality of fingers longitudinally extending from each end of said slide guide and biased so as to conform along their entire length to the ovality of said tube;
- a saddle centrally located between said ends of said slide guide for positioning said slide guide within a tube support sheet;
- and
- a gap interposed between said saddle and said tube for permitting radial expansion and contraction of said tube and said tube support sheet.
