19 Inch Liquid Cooled Frame-I
This type of rack is a copper tube flow channel embedded chassis, and the main frame is vacuum brazed. The internal flow channel is a copper tube flow channel, which is embedded and welded inside the rack through a tin brazing process, with high reliability and good heat dissipation performance. This type of chassis is a customized structure of a 19-inch U-type standard chassis, which can be compatible with various standard daughter cards according to needs.
