Abstract
Official abstract text for this publication.
A rotary regenerative heat exchanger ( 1 ) employs heat transfer elements ( 100 ) shaped to include notches ( 150 ), which provide spacing between adjacent elements ( 100 ), and undulations (corrugations) ( 165,185 ) in the sections between the notches 150 . The elements ( 100 ) described herein include undulations ( 165,185 ) that differ in height and/or width.
First claim
Opening claim text (preview).
What is claimed is: 1. A heat transfer element for a rotary regenerative heat exchanger comprising: notches extending parallel to each other and configured to form passageways between adjacent heat transfer elements upon stacking thereof, each of the notches including lobes projecting outwardly from opposite sides of the heat transfer element; first undulations disposed between the notches, the first undulations extending parallel to each other, each first undulation having a width Wu 1 ; and, second undulations disposed between the notches, and adjacent to and alternating with the first undulations, the second undulations extending parallel to each other, each second undulation having a width Wu 2 , wherein the width Wu 1 is not equal to the width Wu 2 . 2. The heat transfer element of claim 1 , wherein the ratio of the width Wu 2 to the width Wu 1 is greater than 0.2 and less than 1.2. 3. The heat transfer element of claim 1 , wherein the ratio of the width Wu 2 to the width Wu 1 is greater than 0.5 and less than 1.1.
