AI Technical Summary

Technical Problem

In the existing technology, during the vacuum diffusion welding process of liquid-cooled plates, the contact between the pressure head and the surface of the liquid-cooled plate is low, resulting in uneven pressure distribution on the welding surface and pressure loss in local areas. This leads to defects such as loose welds and incomplete welding, affecting the sealing performance.

Method used

It adopts a design of multiple periodically closely laid patterned pressure heads, combined with a rigid load-bearing layer, a buffer layer and a wear-resistant contact layer. Equipped with pressure and temperature sensors, it achieves uniform contact between the pressure head and the liquid cooling plate through lifting components, and adjusts the temperature and pressure in real time to ensure the uniformity of the welding process.

Benefits of technology

This results in more uniform pressure distribution across all areas of the liquid cooling plate, improved welding quality, avoidance of loose welds and incomplete weld defects, and enhanced sealing performance and processing efficiency.
