Analysis of HTRI operation results
Thread Content
As shown in the figure below: Why is the area calculated by HTRI7.3.2 for plate-fin heat exchangers much larger than the geometric area? More than double – could it be that the fin layer is also counted as part of the area?
For finned heat exchangers, the fin layer certainly counts as the heat exchange area, and it is a much larger area! One way to improve heat exchange is to increase the heat exchange area, and fins are one of the methods used to do this!
Which expert can create a tutorial on “the design of plate-fin heat exchangers”, using Aspen or HTRI. To enable everyone to learn and improve!
The heat transfer area-to-volume ratio of plate-fin heat exchangers is generally greater than 800 m2/m3
If the fins of a plate-fin heat exchanger are not counted as part of the area, then what is the purpose of those fins?
