Abstract:
In this paper the lamella heat exchangers were presented. They are used for water and air as operating mediums, and can be differentiated by the shape of the ribs. The one has sinuous type of ribs, while the other one has flat lamella ribs. Better heat transfer can give the exchanger with higher values of coefficient αr and factor ja. A comparison between both types of heat exchangers is made with reference to air velocity in the minimum flow cross ‐ section and Reynolds’ number.
