AI Technical Summary
The existing heat exchangers have problems of sheet misalignment and unnecessary deformation during the manufacturing process, and are difficult to use in environments with limited space. Techniques such as laser bonding and riveting increase manufacturing complexity and energy consumption.
A heat exchanger with alignment ribs is designed to reduce fixing force, improve plate alignment and reduce deformation, and enhance alignment function by setting non-circular protrusions in the plate stack to match the openings of adjacent plates.
The plate alignment before the brazing manufacturing step is achieved, the sheet deformation and misalignment are reduced, and the installation accuracy and flatness of the heat exchanger are improved. It is suitable for high tolerance equipment such as power electronics.
