Technology & Function of Liquid Coolers
Liquid coolers, also known as cold plates, are the ideal solution when air cooling reaches its limits – for example in power electronics, laser modules, data centers, or e-mobility applications. Direct heat transfer to a coolant (water, water-glycol, or dielectric liquid) enables up to 10 times more effective heat dissipation – especially when installation space is limited or component density is high.
For maximum performance, COOLTEC uses internally structured cooling plates (Structureflow). Whether complex channels, pins, fins, or multi-layer systems – our coolers are tailored precisely to your thermal requirements. Depending on the design, we use vacuum brazing, welding, bonding, or additive manufacturing.
Benefits of Our Liquid Coolers
Efficient & Compact: Ideal for high thermal loads and tight spaces – liquids transport heat far better than air.
Diverse Forms & Materials: From standard plates to complex internal structures in aluminum, copper, or stainless steel
Customized & Cost-effective: Technically optimized, economically manufactured – perfect for prototypes and small to medium series.
Sustainable Cooling: Recyclable materials, anodized surfaces, and low-CO₂ production for eco-friendly thermal management.
Sustainable Liquid Cooling for Modern Electronics
Our liquid coolers are made from recyclable materials such as aluminum, copper, or stainless steel – ideal for high cooling performance and a low carbon footprint. Aluminum in particular is nearly 100% recyclable and offers excellent thermal conductivity.
Thanks to energy-efficient manufacturing methods like vacuum brazing and optimized material use, our cooling solutions are sustainable – combining environmental responsibility with technical efficiency. This is how we actively contribute to sustainable thermal management in demanding applications.
Sustainability at COOLTECMore Performance. More Safety. More Service.
Quality Assurance & Leak Testing
Every liquid cooler undergoes comprehensive leak testing – such as helium leak detection or pressure testing – and is reliably cleaned. This ensures maximum operational safety and cleanliness for your system.
Coating & Marking
Whether corrosion protection, electrical insulation, or individual serial numbers – we tailor the surface and marking of your coolers precisely to your application’s requirements.
Simulation & Design of Your Cooling Solution
To achieve an optimal liquid cooling solution, several factors must be considered, including:
- Power loss from electronics
- Geometry and available space
- Flow rate and coolant
- Pressure drop and flow guidance
Our thermal simulation tools enable precise design of coolers – including temperature distribution and flow behavior. This ensures maximum efficiency while minimizing risks of hotspots or oversizing.
