DINKONDA GLOBAL Power Plants Special GA Series Double-layer Thin Plate Composite Stamping Formed Double Wall Plate Heat Exchanger Plates With Dedicated Anti Medium Mixing

Product Overview
The GA series double wall plate heat exchanger plate is a specialized double wall heat exchanger plate for preventing medium mixing. The plate adopts a double-layer thin plate composite stamping structure, which is different from ordinary single-layer plate plates. There is a small leakage detection gap between the two plate plates. Once the plate is perforated or damaged, the medium will leak out from the interlayer, avoiding direct mixing and pollution of the two heat exchange media. It is a core spare part for sanitary and high-risk medium heat exchange conditions. The external dimensions, corner hole specifications, sealing groove positions, and hanging positioning structure of this series of plates follow the original GA series technical parameters, and can be directly adapted to the corresponding model of double wall plate heat exchanger frame without the need to modify the equipment body, clamping plate, and fasteners. It solves the pain points of long procurement cycle and high cost of imported double wall plates and is commonly used for equipment overhaul, spare parts reserve, and process system transformation.

Structural Composition
1. This board is a double-layer double wall exclusive structure, mainly including six major structures: corner hole flow channel area, end flow distribution area, double wall main heat exchange zone, middle leakage interlayer, sealing slot, and positioning hanging ear.

2. Corner hole flow channel area: The size and flow pattern of the four corner flow holes are consistent with the original GA series, ensuring the medium flow area, reducing inlet eddy currents and pressure losses, and adapting to the original flow channel layout of the equipment.

3. End diversion distribution area: The upper and lower diversion ripples are replicated from the original factory design, allowing the medium to evenly cover the entire heat exchange plate surface, eliminating local heat exchange dead zones, and fully utilizing the heat exchange area.

4. Double wall main heat exchange zone: Two independent metal sheets are stamped with herringbone shaped heat exchange ripples, and the wave height, pitch, and inclination angle of the ripples are strictly calibrated to the original factory parameters to ensure that the heat transfer coefficient and pressure drop performance are consistent with the original products.

5. Leakage detection interlayer: A small transparent cavity interlayer is formed between two layers of plates. When corrosion or perforation occurs on either side of the plate, the medium will penetrate the interlayer and leak outward, visually warning of plate failure and preventing the mixing of cold and hot media.

6. Sealing groove: The outer edge of the plate is integrally formed with a sealing groove, which can be matched with original or domestic matching sealing gaskets to achieve external sealing of the medium and ensure the pressure bearing operation of the equipment.

7. Positioning hanging ear: The hanging card size is consistent with the original factory, and can be hung on the heat exchanger crossbeam. The A/B version is alternately assembled to form an independent heat exchange channel.
The conventional materials for the plates are 304 and 316L stainless steel; Special material double wall panels such as 2205 duplex steel and titanium can be customized for strong corrosion conditions.

Technical Features
1. Double wall anti mixing safety design
The double-layer plate interlayer leakage warning structure ensures that the medium leaks outward after the plate is damaged, and there will be no mixing of the two process media, preventing cross contamination of the media and meeting the safety requirements of high-risk media and sanitary processes.

2. Strictly benchmark the original GA series machine for adaptation
The shape, corner holes, ripple parameters, and hanging point positions of the board are completely based on the original GA series technical parameters of the factory. The original equipment frame, clamping components, and sealing gaskets can all be used directly. If a single piece is damaged, it can be replaced separately, and the whole machine does not need to be modified.

3. Heat transfer and flow resistance performance meet the original factory specifications
The geometric parameters of the double wall ripple are replicated according to the original factory standards, ensuring turbulence effects under the premise of a double-layer structure. The equipment's heat transfer efficiency, medium pressure drop, and original plate performance are matched without changing the original system process parameters.

4. The stamping process is stable and the pressure is reliable
Adopting specialized composite stamping technology, the double-layer sheet is formed in a regular manner, the interlayer gap is uniform and controllable, the residual stress is low, and it meets the original design pressure. It is not easy to deform and crack under fluctuating working conditions.

5. Easy to predict faults and reduce production risks
Corrosion and perforation of the board can cause leakage, making it easier for maintenance personnel to detect faults in a timely manner, stop the machine for maintenance in advance, and avoid product scrap, equipment damage, and even safety accidents caused by medium mixing.

6. Domestic spare parts supply guarantee
Avoiding the problem of long lead times for imported spare parts, with short supply cycles and outstanding cost-effectiveness, it is suitable for spare parts storage and maintenance projects for high-risk process equipment in food, medicine, and chemical industries.

7. Convenient maintenance and repair
The disassembly and assembly process is the same as the original factory double wall panels. After disassembling the equipment, each panel can be removed and cleaned. Only the corresponding panel can be replaced for local damage, reducing operation and maintenance costs.
