Abstract
A heat exchange element of a heat exchanger prevents losses due to internal pressure non-uniformity. The heat exchanger includes a plurality of heat exchange sheets which are stacked together. A plurality of airflow guide ribs located between the sheets have connection passages that allow gases to flow between adjacent ducts. The flow of gasses through the connection passages offsets pressure non-uniformity between adjacent ducts. Also, the ribs can be continuously arranged over the length of the heat exchange ducts to increase an area supporting the heat exchange sheets, and thus the sag phenomenon of the heat exchange sheet can be prevented.
Claims22
A heat exchanger, comprising:
- a plurality of heat exchange sheets which are stacked on top of one another;
- and
- a plurality of guide ribs positioned between the heat exchange sheets to form fluid flow ducts between adjacent heat exchange sheets, wherein an aperture is formed in at least one of the guide ribs to allow fluid flow exchange between adjacent fluid flow ducts.
A heat exchange plate for a heat exchanger, comprising:
- a heat exchange sheet;
- and
- a plurality of guide ribs attached to at least one side of the heat exchange sheet, wherein an aperture is formed in at least one of the guide ribs to allow fluid flow exchange through the aperture.
