Heat exchanger when using a given plate, the design of the plate as This stage requires to have some references from suppliers,Įspecially the size of plate they can supply, the max size of the 2.3 STEP 3 : calculating the number of plates required The value of S can thus be calculated, as a 1st approximation of H = overall heat exchange coefficient (kW.m 2.K-1) Out temperatures and the specific heat of the fluid, either on hot The heat flux can be calculated knowing the flowrate, the in and Temperature knowing the characteristics of the heat exchanger forĢ.2 STEP 2 : calculate the required heat flux It can be adapted after, using Excel, to calculate the outlet Procedure here is to size a heat exchanger knowing those data, but

Calculation procedure : plate heat exchanger sizing How to design a plate heat exchanger ? 2.1 STEP 1 : get the design data They can operate in more extreme conditions but cannotīe open for inspection and cleaning. Other designs with welded plates exist (brazed plate heatĮxchangers).
Using gaskets will limit the operating pressure and temperature so Regular cleaning is required for hygiene reasons (food industry). Such aĭesign allows to open and clean very easily the exchanger which willīe appreciable in situations where high fouling is expected or if
Plates pressed against each other with gaskets in between. The company Alfa Laval, people sometimes referring them as "Alfa This kind of heat exchangers have especially been popularized by Will limit the application when high flow rates are involved. Such a design leads as a consequence to high pressure drop which
Interesting proposal when space or costs are a constraint. Heat exchanger compared to other designs which can make them an High heat exchange coefficient and as a consequence a rather compact Plate and frame heat exchangers have a very specific designĬompared to other each exchangers : the fluid is split into wide but Plate heat exchangers definition What is a plate heat exchanger ?
