Plate Heat Exchanger Is A High-Efficiency Heat Exchange Equipment Composed Of Stacked Multi-Layer Corrugated Metal Plate

Introduction to plate heat exchanger
Plate heat exchanger is a high-efficiency heat exchange equipment composed of stacked multi-layer corrugated metal plates. Between these layers, a series of narrow rectangular flow channels are formed, allowing liquid or gas to transfer heat efficiently. This design is particularly suitable for the heat exchange needs of liquid-liquid and liquid-vapor systems.
Plate heat exchangers are known for their high heat exchange efficiency, low energy consumption, compact design and small size. They also have great advantages in floor space, so they are widely used and have a long service life. Its heat transfer capacity is better than traditional tubular heat exchange equipment under the same pressure drop condition, and it can achieve a heat recovery rate of more than 90%

1.One-time stamping and forming of plates

After one-time pressing by special hydraulic equipment, the entire blanking process is completed in one go. During the pressing, we used the soft-coating technology to ensure the high precision and excellent quality of the sheet forming, with a smooth surface without any scratches or stretch marks, and effectively reduced the stress generated during the pressing process. Thickness reduction is uniform across each panel and corrugation depth remains uniform, ensuring tightness at every point of contact between panels. At the same time, there are no over-stamped areas on the board, preventing tiny cracks that can only be observed under a microscope. In addition, the metal texture on the board is consistent in height to ensure the overall beauty, and the thinnest part can reach an accuracy of 0.3mm.

2.Design of slab chocolate-type distribution area

Full and even flow even on even the widest plates Using an innovative cross-shaped (also called chocolate block) design, our plate diverter zones ensure adequate and even flow even on the widest plates. Cover evenly to every corner. This structural design effectively eliminates heat exchange stagnation areas, as well as low flow rate scaling and plate corrosion problems caused by stagnation. Diversion through promotion We have successfully enhanced the heat exchange capacity of the entire plate by improving the heat exchange efficiency in the area and stagnation area. The unique high turbulence design concept is designed to prevent clogging of the inter-plate channels while maximizing self-cleaning effect. In addition, we use the principle of hydrodynamics to adjust the flow resistance in a gradual manner to ensure that the fluid enters between the plates more smoothly and optimizes pressure release.

3.Gasket Design

The carefully designed gasket, whose structure adopts a triangular roof shape, achieves a linear sealing effect. This design is the most stable and reliable form of gasket design. Under the action of clamping force, this structure ensures that the center area of the gasket can withstand the strongest pressure, so that strong sealing pressure can be obtained with smaller force, ensuring outstanding sealing performance. Furthermore, even after repeated disassembly and assembly, the gasket will show only minimal permanent deformation. At the same time, smaller applied forces help prevent plate deformation. The entire tank is designed to be closed to enhance the stability of the overall structure.

4.Characteristics of the frame and positioning system

Utilizing unique positioning technology, we designed a method to prevent the panels from deforming when disassembling and positioning the wall up and down. Through edge processing design, the positioning device still maintains accuracy after repeated disassembly and assembly, and the positioning points are more wear-resistant. In order to improve the automatic alignment effect, we use auxiliary positioning skirts at the four corners of each panel. At the same time, I designed a unique dovetail structure and implemented a multi-point positioning strategy. This positioning method is based on the mechanical positioning principle of "a plane, a fixed pin on one side, and a movable pin on one side", which ensures the freedom of the workpiece in one direction, thus effectively avoiding the problem of over-positioning.

5.Quick installation structure design

The front clamping nut is integrated with the screw through a locking bolt. There is a bearing box underneath. The rear clamping nut is prevented from loosening by a unique locking sleeve. When disassembling the plate heat exchanger, you only need to tighten or loosen the front clamp. It can be completed by tightening the nuts. It is more convenient and faster to disassemble and assemble when inspecting the plate heat exchanger. It is a typical user-friendly design.
All parts of the frame are connected with threads.
The compression bolts are manufactured by roll rolling.
There is a bearing box on the compression bolt.
Pressure screws can be removed laterally
