DINKONDA GLOBAL Power Plants Special Plate Heat Exchanger A/B Paired With Herringbone Corrugations, Diagonal Flow Heat Exchanger Plates

Product Overview

This set of products is paired with A-type and B-type herringbone corrugated heat exchange plates, which serve as the core heat exchange elements of plate heat exchangers. The corrugated directions of the two plates are matched with each other, and after assembly, they can form staggered cold and hot medium flow channels. Adopting high-precision integrated stamping process, completely benchmarking the size of imported prototype plates, achieving domestic substitution. Paired use can maximize the enhancement of fluid turbulence effects, adapt to maintenance, spare parts replacement, and unit renovation projects of plate exchange equipment in heating, industrial cooling, chemical heat exchange, and other scenarios, significantly shorten delivery cycles and reduce equipment operation and maintenance costs while ensuring equivalent heat exchange performance of imported components.

Structural Composition

The whole set includes two types of paired plates, A plate and B plate. The outer contour and four medium through holes of the two plates are consistent in size, and the ripple direction is opposite. They are designed for paired use:

1. * * Herringbone Ripple Heat Transfer Zone * *: The main body of the plate is covered with continuous herringbone stamping patterns, and the A/B plate ripples intersect and bite. The fluid constantly changes direction in the narrow channel, breaking the fluid boundary layer and enhancing heat transfer.

2. * * Four corner medium guide holes * *: Large diameter medium holes are opened at the four corners of the plate to allow the cold and hot media to flow in and out from the opposite corners, achieving complete separation and countercurrent heat transfer between the two media.

3. * * Sealing rubber groove position * *: The outer edge of the plate is integrally formed into a continuous sealing groove, which is used to embed sealing gaskets, isolate the heat exchange channel from the outside, prevent internal flow and external leakage of the medium, have high groove accuracy, and the gasket fits tightly.

4. * * Positioning hanging ears and buckles * *: The standardized hanging and positioning structure is designed on the upper and lower edges of the plate, which can be directly hung on the heat exchanger clamping frame to ensure accurate alignment of the hole positions when multiple plates are stacked and assembled, and the flow channel will not be offset or short circuited.

5. * * Corner diversion zone * *: Diamond shaped mesh diversion patterns are designed on the inner side of the four hole positions to evenly distribute the medium entering the heat transfer zone, avoiding local high flow velocity and bias, and fully utilizing the heat transfer area of the entire plate.

Product Highlights

1. * * A/B pairing collaborative design for higher utilization of heat exchange area**
The plates are divided into A and B matching patterns, and after assembly, the ripples support each other. The channel width is uniform, and the medium will not have any bias or dead corners. Compared to a single plate, the cold and hot media can fully contact the entire plate surface, and the heat transfer capacity is stronger under the same heat transfer area, making it suitable for small temperature difference heat transfer conditions.

2. Integrated stamping of the mold, uniform stress on the plate surface, and strong pressure resistance**
Using large precision molds for one-time stamping and forming, the thickness of the sheet is uniform, and the consistency of the corrugated forming is good. Under the clamping force and medium pressure of the heat exchanger, local bulging, deformation and perforation are less likely to occur, and it can stably withstand the rated pressure of the equipment for a long time, reducing the risk of plate bursting during operation.

3. Diversified material solutions, targeted resistance to corrosion from various media**
Customization of substrates such as 304, 316L, 2205 duplex stainless steel, TA1 titanium plate, etc. is available upon request. 304/316L is selected for ordinary water circulation heat exchange; 2205 duplex steel is selected for chloride ion and weak acid working conditions; Titanium is selected as a highly corrosive chemical medium to solve the problem of corrosion perforation in a targeted manner.

4. * * Standardized full-size replication, on-site disassembly and assembly with zero modifications**
The shape, hole spacing, hanging ear position, and sealing groove contour of the board are all aligned with the prototype board. Replacing old equipment with spare parts does not require modifying the heat exchanger frame, clamping bolts, and pipelines. Maintenance personnel can directly replace them, greatly reducing downtime for maintenance and minimizing production losses.

5. The self flushing characteristics of the flow channel delay the accumulation of scale on the plate surface**
The strong turbulence caused by the herringbone ripple has a certain self flushing effect on small impurities in the medium, slowing down the deposition of dirt on the surface of the board, extending the cleaning cycle, and reducing the frequency and cost of equipment cleaning and maintenance.

6. * * Domestication is flexible and can be purchased separately for plates or complete sets of plates and sealing gaskets as spare parts**
Domestic production stocking, short supply cycle, supports scattered spare parts procurement, and does not require bulk whole unit ordering. We can purchase plates separately or purchase complete sets of rubber sealing gaskets of the same model to meet maintenance needs in one stop.
