Efficient channels and low thermal resistance
Optimized coolant distribution and low-resistance channel design work with high-conductivity copper cold plates for efficient heat transfer.
Single-phase cold plate series
SynthCool Nusselt™ covers high-density cooling for ICCP optical modules, 1PIC NVIDIA GB300 modules, GPU devices, optical modules, and server boards, providing a low-thermal-resistance, reliable, and scalable cold-plate product matrix.
Typical productsSynthCool Nusselt™ ICCP optical module; SynthCool Nusselt™ 1PIC NVIDIA GB300 module.
Stable chip-level heat extraction for scalable delivery.
Reliable welding and corrosion protection
Reliable welded structures support pressure bearing and sealing, while full-channel corrosion protection improves long-term durability.
Integrated safety protection
Integrated pipe interfaces, drip trays, leak detection, and alarms create system-level protection and reduce leakage risks.
High-standard manufacturing and validation
Critical manufacturing steps are tightly controlled, with non-destructive testing, air tightness, flow resistance, cleanliness, and dry nitrogen protection.
