Abstract
Apparatus comprising a combination tube support for supporting tubes within a shell and tube type heat exchanger and baffle for directing fluid flow within the heat exchanger. A baffle lip is mounted on a baffle body to provide a seal with the interior surface of the heat exchanger shell. A foot having support surfaces of varying heights is used to support the baffle body to prevent the weight of the baffle body and the tubes contained therein as well as other forces from collapsing a portion of the baffle lip.
Claims8
In a heat exchanger for transferring heat from a first fluid to a second fluid having a shell for containing the flow of the first fluid and having mounted within the shell tubes for containing the flow of the second fluid, a combination tube support for securing the tubes and baffle for directing the flow of the first fluid which comprises:
- a baffle body having tube retaining holes in which the tubes are mounted;
- a resilient baffle lip mounted to the baffle body, said lip extending from the perimeter of the baffle body to the inside surface of the shell to form a relatively fluid tight seal therebetween;
- and
- means for preventing the complete collapse of a portion of the baffle lip, said means including a foot accommodating notch in the baffle and a foot having a plurality of support surfaces at varying heights to fit within the notch and against the inside surface of the shell to support the baffle and the tubes at varying heights within the shell.
The apparatus as set forth in claim 11 wherein the sides of the tube and shell heat exchanger are crimped on either side of the combination tube sheet and baffle to secure the tube sheet and baffle in place, the crimped tubes having a greater cross-sectional dimension than the inside diameter of the tube retaining holes in the baffle.
In a heat exchanger for transferring heat from a first fluid to a second fluid having a shell for containing the flow of the first fluid and having mounted within the shell tubes for containing the flow of the second fluid, a combination tube support for securing the tubes and baffle for directing the flow of the first fluid which comprises:
- a baffle body having an outside diameter less than the inside diameter of the shell and having tube retaining holes in which the tubes are mounted;
- a resilient baffle lip substantially thinner than the baffle body and mounted to the baffle body, said lip having a greater outside diameter than the inside diameter of the shell such that the lip is partially displaced upon insertion into the shell and extends from the perimeter of the baffle body to the inside surface of the shell to form a relatively fluid tight seal therebetween;
- and
- means for supporting the baffle body and tubes contained therein to protect the baffle lip from receiving all of the load transmitted through the baffle body including a foot accomodating notch in the baffle, and a foot adapted to fit within the notch and against the inside surface of the shell to support part of the weight of the baffle and the tube secured therein whereby complete collapse of a portion of the baffle lip is prevented to maintain the seal between the baffle body and the shell.
A combination tube support for securing tubes and baffle for directing fluid flow which comprises:
- a baffle body having a plurality of tube retaining holes and a foot accommodating notch;
- a baffle lip mounted to the baffle body, said lip extending beyond the periphery of the baffle body and being resilient so that it may be displaced to form a fluid tight seal;
- and
- a foot having a plurality of foot support surfaces at varying foot heights, said foot being inserted within the notch so that the weight of the baffle and any tubes therein may be partially supported by the foot, the foot support surface selected for insertion into the notch being dependent on the height at which it is desired to support the baffle body.
