The selection of process of plate heat exchanger

by:DIGUANG     2020-08-08
Plate heat exchanger type selection of process for general symmetry flow plate heat exchanger, the same two fluid volume flow, should as far as possible according to the process arrangement; If the difference on both sides of the flow, the flow of small side can take multiple process layout. Phase change of phase change on one side of the plate heat exchanger in general are one-way. Multi-pass plate heat exchanger, unless special needs, generally on the same fluid in each process should be taken to the same port number. In a given total allowed pressure drop, plate heat exchanger multipass arrangement to make every process corresponding to allow smaller pressure drop, forced flow is reduced, heat exchange. In addition, ranging from cheng cheng more arrangement is one of the important reasons for reducing the average heat transfer temperature difference, should be avoided as much as possible.
