Two-Phase Cold Plate
Two-phase cold plates efficiently remove heat from processors and high-power components by utilizing the latent heat of vaporization during the liquid-to-vapor phase transition of the coolant. Compared with single-phase cold plates, which primarily rely on liquid circulation and temperature rise for heat dissipation, two-phase cold plates can transfer substantial amounts of thermal energy at lower flow rates and with smaller temperature variations. This makes them particularly suitable for high-heat-flux applications, including AI processors, GPUs, and high-power electronic equipment.
Pure Water Negative-Pressure Two-Phase Cooling Technology
boiling point CreAlien has developed Water Two-Phase Cooling (W2PC) technology, which utilizes a low-pressure circulation environment to lower the of pure water, allowing it to vaporize inside the cold plate at an operating temperature of approximately 45°C. As pure water absorbs heat from the chip, it transforms into vapor and subsequently condenses back into liquid, establishing a continuous cooling cycle.
By leveraging phase-change heat transfer, the system achieves highly efficient cooling at lower liquid flow rates while reducing pump power consumption and the demands on the fluid circulation system. Under specific design and testing conditions, the heat transfer performance of two-phase cooling can be approximately 10 to 20 times greater than that of conventional single-phase convective cooling. Actual performance depends on factors such as operating pressure, flow rate, heat flux, flow channel geometry, and condenser system design.
Key Features
- Precision Flow Channel Design and Two-Phase Flow Control
Both liquid and vapor coexist within the flow channels of a two-phase cold plate. The flow channel design must carefully balance coolant distribution, vapor removal, and condensate return. Improper design may lead to flow instability, localized dry-out, or thermal hotspots.
Through precision machining and process control, CreAlien carefully manages microchannel geometry and distribution to ensure stable coolant flow across high-heat-load regions while facilitating efficient vapor removal and recovery.
- High-Density and Space-Efficient Thermal Design
As the power density of AI processors and high-performance computing components continues to increase, cooling systems must accommodate greater thermal loads within limited installation spaces. By utilizing phase-change heat transfer, two-phase cold plates provide highly efficient chip-level cooling without requiring a substantial increase in liquid flow rates.
CreAlien offers customized cold plate structures, flow channel layouts, inlet and outlet configurations, and condensation circulation systems based on customer requirements, helping customers achieve high-power, high-reliability thermal management integration within space-constrained environments.
- Customized System Integration
The performance of a two-phase cold plate depends on the coordinated operation of its structural design, operating pressure, coolant flow rate, and condensation system. Based on the thermal loads and installation requirements of AI processors, data center servers, power electronics, and other high-power devices, CreAlien provides tailored two-phase cooling solutions that meet requirements for thermal performance, fluid control, manufacturing precision, and system integration.
