Plate heat exchanger plate corrugated runner and structure analysis

We all know that the plate is the core heat exchanger plate heat exchanger element, the plate of the ripple, angle, composition of the flow channel design, as well as its own structure will have a profound impact on the efficiency of heat transfer.

Generally, there are two types of corrugations on a sheet, Low Theta and High Theta. As shown in the figure below.

High Thetaand Low Thetacorrugations can be combined or cross-combined to form three flow channels, which can be suitable for different working conditions, and can be customized for special working conditions.

Low Thetaflow channels are suitable for low turbulence and pressure drop, mixed angle flow channels are suitable for medium turbulence and pressure drop, high thetaflow channels are suitable for high Turbulence and pressure drop. The advantages of these three combinations are a variety of flow channel combinations, high heat transfer efficiency, excellent design, high shear, turbulence, not easy to Fouling buildup can improve heat recovery efficiency.

The versatility of the corrugated design provides support points on the surface of the sheet, which can now be designed up to around 0.4mm, enhancing the The strength of the plates creates a high degree of turbulence, which improves the heat transfer coefficient.

The plate construction typically includes suspension slots, inlets and outlets, conduit areas, sealing slots, leakage slots, and major heat transfer areas.This structure allows the medium to flow evenly across the surface of the plate, eliminating heat transfer dead, increasing the effective heat transfer area and improving the heat transfer efficiency. Heat exchange efficiency, not easy to scale, easy to install.

Plate heat exchanger plate ripples, runners and structural design are all designed to serve the heat exchanger itself, mainly to allow the heat exchanger to improve the heat transfer performance, to extend the service life, I believe that the plate design can be more efficient in the future.
