, now look at it with Xiaobian.
First, the choice of plate type of plate heat exchanger.
The plate type or corrugated type should be determined according to the actual needs of the heat exchange occasion. For a large flow rate and a small allowable pressure drop, a plate with a small resistance should be selected, and a plate with a large resistance should be used. Depending on the pressure and temperature of the fluid, determine whether to choose a detachable or brazed type. When determining the plate type, it is not appropriate to choose a plate with a small plate area, so as to avoid too many plates, the flow velocity between the plates is too small, and the heat transfer coefficient is too low. This problem should be paid more attention to for larger heat exchangers.
Second, the choice of processes and runners.
A process refers to a group of parallel flow channels in a plate heat exchanger in the same direction, and a flow channel refers to a medium flow channel composed of two adjacent plates in the plate heat exchanger. In general, several flow channels are connected in parallel or in series to form different combinations of cold and hot medium channels.
Third, the pressure drop check.
The design and selection of plate heat exchangers generally have certain requirements on pressure drop, so they should be checked. If the check pressure drop exceeds the allowable pressure drop, the design selection calculation needs to be performed again until the process requirements are met.
The above is the information about the plate heat exchanger
