High-Performance Liquid Cooling for High Heat Flux Applications
The increasing power of processors, AI accelerators, laser systems, and power electronics requires ever more efficient cooling solutions. When air-cooled heat sinks reach their limits, direct liquid cooling becomes the preferred technology for efficiently removing heat while maintaining controlled operating temperatures.
Since 2020, TEMISTh has been developing custom cold plates for the most demanding applications, combining advanced thermal simulation, CFD optimization, and metal additive manufacturing.
Our objective is straightforward: to design cold plates that simultaneously deliver ultra-low thermal resistance and minimal hydraulic pressure drop, thereby improving the overall performance of cooled systems.
A Design Tailored to Your Application
Every project begins with a detailed analysis of the thermal environment and integration constraints:
- Dissipated power
- Heat flux distribution
- Maximum allowable temperature
- Available flow rate
- Mechanical envelope
- Assembly and maintenance requirements
Based on these inputs, our engineers develop a dedicated hydraulic architecture that brings the coolant as close as possible to the regions experiencing the highest thermal loads.
Unlike standardized solutions, every TEMISTh cold plate is designed around the actual requirements of the component being cooled.
Extremely Low Thermal Resistance
Thermal resistance is one of the key performance indicators of a cold plate.
Through optimization of coolant flow paths and heat transfer surfaces, TEMISTh cold plates achieve outstanding performance levels, with thermal resistances as low as 0.0025 m²·K/W.
Customer Benefits
- Reduced junction temperature
- Extended component lifetime
- Improved electronic performance
- Increased system reliability
- Capability to manage extremely high power densities
This approach is particularly well suited to cooling next-generation processors and accelerators, whose heat fluxes far exceed those of traditional computing architectures.
Minimized Pressure Drop
Thermal performance should never come at the expense of hydraulic efficiency.
Through extensive optimization work, TEMISTh designs internal geometries that provide:
- Uniform flow distribution
- Excellent heat transfer efficiency
- Low pressure losses
- Reduced pumping power requirements
User Advantages
✅ Lower energy consumption
✅ More compact pumps
✅ Optimized system cost
✅ Increased hydraulic circuit reliability
✅ Easy integration into existing equipment
Achieving the right balance between heat transfer and pressure drop is now one of the key differentiators of a high-performance cold plate.
CFD Optimization and Numerical Simulation
Before manufacturing, every cold plate is validated using advanced thermal and fluid dynamics simulation tools.
These models enable:
- Identification of hot spots
- Analysis of flow distribution
- Optimization of microchannel designs
- Evaluation of thermal performance
- Reduction of prototyping risks
Simulation also allows comparison of multiple architectures and selection of the solution offering the best compromise between cooling performance, compactness, and hydraulic efficiency.
Metal Additive Manufacturing: Pushing Cooling Performance Further
Metal additive manufacturing technologies open new possibilities for liquid cooling.
TEMISTh develops cold plates incorporating:
- Complex internal flow channels
- Enhanced heat transfer structures
- Optimized flow distributors
- Geometries impossible to machine using conventional manufacturing methods
This design freedom increases performance while reducing weight and minimizing the number of components.
