DINKONDA GLOBAL Power Plants Special Detachable Plate Heat Exchanger Cross Composite Diagonal Corrugated Diagonal Flow Heat Exchanger Plate

DINKONDA GLOBAL Power Plants Special Detachable Plate Heat Exchanger Cross Composite Diagonal Corrugated Diagonal Flow Heat Exchanger Plate

Product Overview

This plate heat exchanger is a single independent diagonal flow heat exchange element, which is the core heat transfer substrate of the detachable plate heat exchanger. Adopting integrated precision molding, the ripple and overall contour of the flow channel completely match the imported prototype plate type. As a domestic replacement spare part, it can be directly assembled into the corresponding model plate heat exchanger frame. The plate adopts a symmetrical fluid flow guiding structure, and the medium distributes hot and cold fluids through the four corner holes of the plate, relying on the composite corrugated structure on the plate surface to enhance heat transfer. Suitable for major repairs and replacements of heat exchange equipment, as well as technical upgrades and expansions of heat exchange systems. While ensuring that the heat exchange performance matches the original factory specifications, it significantly reduces spare parts procurement costs and shortens delivery cycles.

Structural Composition

1. * * Central composite corrugated heat exchange zone**
The central part of the plate is the main heat transfer area, which adopts a cross composite oblique ripple design. The fluid continuously changes direction in the narrow channel, continuously destroys the fluid boundary layer, forms high-intensity turbulence, and improves the heat transfer coefficient. The corrugations are evenly formed, and after the plate is assembled, the corrugations can support each other, improving the pressure bearing capacity.

2. * * Four corner medium flow hole**
Circular medium channel holes are set at the four corners of the plate, arranged diagonally to achieve counter current heat transfer of cold and hot media. The two media flow independently between adjacent plates without mixing with each other. Strengthen embossing treatment on the edge of the orifice to reduce the erosion and wear of the medium inlet.

3. * * Mesh shaped diversion zones at both ends**
Between the upper and lower openings of the plate and the main corrugated area, a diamond shaped mesh guide pattern is set up to evenly distribute the fluid, spreading the medium entering the channel evenly to the entire heat exchange surface, avoiding local high flow velocity and bias flow, and fully utilizing the entire heat exchange area.

4. * * Outer edge sealing slot**
The outer periphery of the plate is pressed with a continuous annular sealing groove, which is used to embed rubber sealing gaskets, isolate hot and cold media, prevent internal flow and external media leakage. The groove has high contour accuracy, good gasket fit, and reliable sealing after compression.

5. * * Side positioning mounting clip**
Standardized suspension slots are designed on both sides of the plate to hang and fix the plate between the heat exchanger clamping plates. During assembly, ensure that all plate holes are aligned and the flow channels are accurately aligned to avoid medium short circuits.

Core Advantages

1. * * Symmetrical flow channel layout, suitable for bidirectional medium working conditions**
The plate adopts a symmetrical upper and lower structure, with symmetrical layout of medium inlet and outlet, and interchangeable flow directions of cold and hot media, making it easy for the process system to switch between cold and hot circuits. It has stronger adaptability to seasonal heat exchange conditions (winter heating, summer cooling).

2. * * Composite ripple design, balancing heat transfer efficiency and anti scaling ability**
Different from a single herringbone ripple, this model adopts a composite ripple configuration. While ensuring high heat transfer performance, the flow channel has a certain self flushing effect. Small suspended solids in the medium are not easily deposited and attached, which extends the chemical cleaning cycle of the equipment and reduces the workload of operation and maintenance.

3. * * High precision mold stamping, high flatness of the board surface, excellent deformation resistance**
Using large precision molds for one-time stamping and forming, the thickness distribution of the board is uniform, and the flatness of the board surface is high. Under the alternating action of clamping force and medium pressure in the heat exchanger, the plates are less prone to local bulging deformation, and have excellent fatigue resistance during long-term operation, reducing the risk of plate perforation.

4. * * Multiple materials to choose from, covering corrosion conditions in multiple industries**
Materials such as 304, 316L stainless steel, 2205 duplex steel, TA1 titanium, etc. can be selected as needed. 304/316L is used for ordinary circulating water heat exchange; 2205 duplex steel is used for high chloride ion and weakly corrosive media; Titanium is selected as a highly corrosive chemical medium to solve the problem of corrosion perforation in a targeted manner.

5. * * Original factory size replica, on-site replacement does not require equipment modification**
The shape, hole spacing, hanging ear position, and sealing groove contour of the plate are completely aligned with the prototype plate. During equipment maintenance, the old plate can be directly replaced without changing the heat exchanger frame, clamping bolts, and external pipelines, greatly reducing downtime for maintenance.

6. * * Wide range of gasket adaptation**
The standardized sealing groove structure can be matched with various sealing gaskets such as EPDM, NBR nitrile rubber, FKM fluororubber, etc., to meet different medium temperatures and chemical conditions, and the selection of spare parts is flexible.
