1. The use of thermal mixing board: the geometric structure of the ripples on both sides of the thermal mixing board is same. The plates is divided into hard plate (H) and soft plate (L) according to the angle of the herringbone wave. The included angle (usually about 120 degrees) is greater than 90.
2.Using asymmetrical plate heat exchanger: symmetrical plate heat exchanger is composed of plates with the same corrugated geometric structure on both sides of the plate, forming a plate heat exchanger with equal cross-sectional areas of cold and hot runners.
3.Using multi-process combination: When the flow of cold and hot medium is large, multi-process combination arrangement can be used, and more processes are used on the side of small flow to increase the flow rate and obtain a higher heat transfer coefficient.
4. Plate heat exchanger bypass pipe: When the flow of cold and hot medium is relatively large, a bypass pipe can be set at the inlet and outlet of the plate heat exchanger on the large flow side to reduce the flow into the plate heat exchanger and reduce the resistance.
