When it comes to water-cooled plate radiators, it is necessary to mention the structural requirements of the water-cooled plate. In order to ensure the normal use of the water-cooled plate radiator, special attention needs to be paid to the structural design of the water-cooled plate. Overall, the material, sealing effect, and welding method of the water-cooled plate will have varying degrees of impact on the functionality of the water-cooled plate radiator. Let's learn about it together today!
1. Regarding the selection of materials. In general, the materials of water-cooled plates in water-cooled plate radiators mainly include aluminum, copper, and stainless steel. Among them, the use of aluminum materials is particularly widespread. This is because, compared to other materials, aluminum has a lower density and a higher thermal conductivity, making it cheaper among the three. So overall, the cost-effectiveness of aluminum raw materials is relatively high.
2. Regarding the requirements for sealing. Currently, the sealing methods for water-cooled plate radiators mainly include O-Ring sealing and welding. The former is generally used in situations with lower pressure, and also needs to consider issues related to high temperature resistance and aging resistance. And welding can make the entire cold plate integrated, so it can achieve high reliability and durability. Welding methods include vacuum brazing, mixed conflict welding, etc.
3. In the process of welding the water-cooled plate of the radiator, different methods can be used. Common methods include nitrogen maintenance brazing, vacuum brazing, argon arc welding, and mixed conflict welding. Generally, the appropriate welding method is selected based on the raw materials and thickness. For example, nitrogen maintenance brazing and vacuum brazing are generally suitable for products with thin walls and small mass.
Finally, it is also necessary to consider the placement of the flow channel, so when designing the structure, the method of combining upper and lower plates is generally chosen. The base and cover plate can be connected by welding to form an integrated water-cooled plate radiator. It should be noted that the welding surface and pipe joint holes of the water-cooled plate radiator should avoid the heat absorbing surface.
