The detachable plate heat exchanger is made of many stamped corrugated thin plates at a certain interval, sealed with gaskets around them, and laminated and compressed by a frame and a compression screw. The four corner holes of the plates and gaskets form a fluid divider. The piping and collection pipe, while reasonably separating the cold and hot fluids, make them flow in the flow channels on both sides of each plate, and heat exchange through the plates.
The optimization design calculation of the plate heat exchanger is to reasonably determine its model, process and heat transfer area under the condition of known temperature difference ratio NTUE, so that NTUp is equal to NTUE.
