High Temp Resistant Water Cooled Plate For Industrial Machinery

1. Precision milling groove+vacuum brazing process

Using high-precision CNC milling technology, uniform and smooth flow channels are machined on copper, aluminum or copper aluminum composite substrates, with a dimensional tolerance of ± 0.01mm to ensure uniform flow of coolant and no dead corners, maximizing the heat exchange area; Subsequently, the vacuum brazing process is used to achieve seamless bonding between the channel cover plate and the substrate. The welding points are dense without virtual welding or leakage, and there are no gaps in heat conduction. The thermal conductivity efficiency is increased by more than 40% compared to traditional splicing processes. At the same time, the overall structural rigidity is strengthened, and the ability to resist vibration and deformation is excellent. ​

Application adaptation: Widely used in medium and high-power equipment such as new energy battery packs, photovoltaic inverters, power semiconductors, etc., especially suitable for scenarios with strict requirements for heat dissipation efficiency and sealing such as new energy vehicle on-board electronic control and energy storage power station modules, quickly dissipating concentrated heat from equipment and ensuring long-term stable operation of core components. ​

2. Friction Stir Welding Process

In response to the requirements of high pressure and high load working conditions, friction stir welding technology is adopted, which does not require the filling of solder. Through high-temperature and high-pressure stirring, the integrated welding of the substrate and the cover plate is achieved. The weld seam is smooth, has high strength, excellent sealing performance, and can withstand high pressure of 10-30MPa, eliminating the hidden danger of coolant leakage; After welding, there is no thermal deformation, and the internal flow channel is smooth without burrs, reducing the flow resistance of the coolant and further improving the heat exchange efficiency, suitable for long-term continuous high load operation scenarios. ​

Application adaptation: Industrial high-frequency frequency converters, heavy machinery electrical control systems, high-power laser equipment and other high-voltage and high load equipment can maintain stable heat dissipation in harsh industrial environments, avoiding equipment short circuits, damage and other problems caused by coolant leakage.

3. Surface protection treatment process

Based on the substrate material and usage scenario, surface treatment processes such as anodizing, electroplating nickel, and passivation are used to form a dense protective layer on the surface of the water-cooled plate, effectively enhancing its anti-oxidation, anti-corrosion, and dust-proof properties, resisting moisture, oil pollution, and dust erosion in industrial environments, and avoiding the decrease in thermal conductivity caused by substrate oxidation and corrosion; Simultaneously optimizing the surface adhesion, reducing the contact thermal resistance with the heating elements of the equipment, and further improving the heat dissipation efficiency. ​

Application adaptation: Suitable for complex environments such as outdoor communication base stations, damp and dusty workshops, outdoor photovoltaic energy storage equipment, etc., extending the service life of water-cooled panels, reducing maintenance frequency, lowering equipment operation and maintenance costs, and adapting to long-term outdoor or harsh industrial environments. ​

4. Sealing and reinforcement process

High temperature and high pressure resistant sealant is used to seal key areas such as water-cooled plate interfaces and welds, reinforced with precision sealing rings to ensure dual sealing performance and prevent coolant leakage; At the same time, the interface is standardized and adapted to different specifications of coolant pipelines, making installation convenient and enabling quick integration with equipment cooling systems, reducing assembly difficulty and time costs. ​

Application adaptation: Suitable for cooling systems of various medium and high-power equipment, especially for scenarios with high sealing performance requirements such as new energy vehicles and energy storage power stations, ensuring long-term stable operation of the cooling system without leakage hazards.
