Abstract
The disclosure relates to fin inserts for heat and mass exchangers and corresponding methods. For instance, in some examples, a fin insert to a heat and mass exchanger includes a generally rigid, longitudinally-extending member that includes a top portion and side portions. The side portions may be disposed on opposite sides of the top portion, and may include a concave shape facing away from one another. The side portions may further are each be positioned around a portion of a respective heat transfer tube.
Claims20
A fin insert comprising:
- a generally rigid member comprising a top portion and side portions, the side portions being disposed on opposite sides of the top portion,
- wherein the side portions comprise a concave shape facing away from one another and are each configured to be positioned to create a fluid channel around a corresponding portion of each of two horizontally adjacent heat transfer tube,
- wherein the generally rigid member is formed of a sheet and is elongated in an axial-direction between two horizontally adjacent heat transfer tubes.
A heat transfer assembly comprising:
- a row of at least three parallel heat transfer tubes horizontally spaced apart from one another with a fin insert disposed between adjacent pairs of the heat transfer tubes;
- each fin insert comprising a generally rigid, member comprising a top portion and side portions disposed on opposite edges of the top portion, the fin insert being disposed between the two parallel heat transfer tubes;
- wherein each generally rigid member is formed of a sheet and is elongated in an axial-direction between two horizontally adjacent heat transfer tubes;
- a plurality of spacers disposed between the side portions of the fin insert and a respective heat transfer tube, such that the side portions are spaced apart from the heat transfer tubes;
- and
- at least one fluid channel formed between the respective side portion and heat transfer tube.
A heat transfer assembly, comprising
- a generally rigid corrugated sheet;
- and
- a row of horizontally-spaced heat transfer tubes,
- wherein the corrugated sheet is corrugated in both an axial-direction of the heat transfer tubes and a transverse-direction of the heat transfer tubes;
- wherein the corrugation in the axial-direction of the heat transfer tubes comprises mounting portion peaks and fluid flow channel grooves between adjacent mounting portions;
- wherein a portion of each heat transfer tube contacts each of the mounting portions;
- wherein each fluid flow channel is spaced apart from the heat transfer tube to which is it attached, and
- wherein each mounting portion is shaped to direct the fluid to flow towards the fluid flow channel.
