The company has a strict quality control system, from production process management to factory inspection and control to ensure product performance and quality. The
choice of the plate type of the plate heat exchanger will
now be reviewed with Xiaobian.
1. Plate type selection.
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 fluid pressure and temperature, determine whether to choose a detachable or brazed type. When determining the plate type, it is not appropriate to choose a plate with a too small 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.
2, the choice of processes and runners.
A flow refers to a group of parallel flow channels in the same direction of a medium in a plate heat exchanger, and a flow channel refers to a medium flow channel composed of two adjacent plates in a 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.
The process combination form should be calculated based on heat exchange and fluid resistance, and determined under the requirements of process conditions. Try to make the convective heat transfer coefficients in the cold and hot water flow channels equal or close, so as to have a heat transfer effect. Because the convective heat transfer coefficients on both sides of the heat transfer surface are equal or close, the heat transfer coefficient gets a larger value.
