  • High-Density Computing: Modular computing units such as Meta Clemente 1U 4-GPU compute sleds
Cold Plate Radiator Design

We design internal flow channels based on customer-provided power consumption data and heat distribution patterns to meet specific temperature rise and uniformity requirements while maintaining acceptable fluid flow resistance.

Our design process includes comprehensive simulation analysis of temperature and pressure drop, with iterative adjustments to internal parameters until both thermal and hydraulic performance targets are achieved.

Advanced Brazing Technology

Our vacuum brazing process joins aluminum plates using filler metal with lower melting points than the base material, creating extremely strong joints without residual corrosive flux. This high-end technology provides uniform heating, precise temperature control, eliminates post-cleaning requirements, and minimizes part distortion.
