Liquid Cooling Solutions for High-Powered Applications
As devices become faster and more complex, managing heat efficiently is essential. For high-powered applications, liquid cooling stands out for its ability to handle dense components and high temperatures far better than traditional air cooling. Whether you’re in automotive, telecom, industrial automation, or renewable energy, liquid cooling solutions are critical to ensuring stable, long-lasting performance.
Understanding Liquid Cooling
Liquid cooling transfers heat away from high-temperature components by circulating coolant through a system. This not only prevents overheating but also prolongs equipment lifespan. Below are six categories of liquid cooling solutions, each suited to specific applications and environments.

Top Five Essential Liquid Cooling Solutions:
Tube Embedded Cooling Plates
Versatile and Direct Cooling
Tube embedded cooling plates feature tubes embedded directly into the plate, allowing the coolant to flow close to the heat source. This design enables quick and efficient heat transfer in a compact footprint, making it highly adaptable to various requirements.
Types of Embedded Cooling Plates
- Stainless Tube Embedded: Corrosion-resistant, making it ideal for applications exposed to harsh conditions, such as outdoor telecom installations.
- Copper Tube Embedded: Offers high thermal conductivity and is widely used in power electronics and automotive systems, like battery cooling in electric vehicles (EVs).
Benefits of Embedded Cooling Plates
- Compact, space-efficient design
- High durability in challenging environments
- Effective heat transfer for stable performance
Applications
These plates are commonly used in power systems like EV batteries, telecom stations, and renewable energy converters, where efficient, direct cooling is essential.

Friction Stir Welding (FSW)
Seamless Joints for Heavy-Duty Performance
Friction stir welding is a solid-state joining process that fuses materials without melting, resulting in high-strength, defect-free bonds. This process is especially useful for applications where durability and reliability under continuous heat loads are essential.
Complex Part FSW allows for intricate shapes, commonly used in components with strict space limitations but high cooling needs, such as motor controllers in electric transportation.
Benefits of Friction Stir Welding
- High-strength, defect-free joints for durability
- Stable performance under continuous heat loads
- Adaptable for complex shapes and designs
Applications
FSW is frequently used in automotive powertrains and high-performance robotics that require reliable cooling under continuous stress. In electric powertrains, for example, FSW components maintain stable cooling and durability under intense operational loads.

Copper Brazing
Strong, Reliable Thermal Pathways
Copper brazing joins copper components using a filler material, creating a strong, conductive bond without melting the base metals. This process maintains copper’s excellent thermal conductivity and offers a robust connection.
Types of Embedded Cooling Plates
- Standard Copper Brazing: This technique is used widely across power electronics and data centers for consistent, efficient heat transfer.
- Vacuum Copper Brazing: Used in environments sensitive to contaminants, such as cleanrooms, vacuum brazing eliminates impurities, resulting in a clean, high-integrity bond ideal for precise, contaminant-free cooling.
Benefits of Copper Brazing
- High thermal conductivity for consistent cooling
- Strong, durable bonds for long-term reliability
- Ideal for clean environments when vacuum-brazed
Applications
Common in automotive powertrain systems and industrial data centers where heat dissipation needs to be stable under heavy loads. In EVs, copper brazing ensures efficient heat management in charging systems, maximizing performance and battery life.

Radiator Cold Plates
Radiator cold plates are designed with a network of channels and fin structures that allow liquid coolant to circulate through the plate, pulling heat away from the target component. These channels resemble a radiator, where the coolant absorbs heat and then dissipates it as it flows through the plate’s finned structure.
Construction and Features
- Finned Channels: Built-in fin structures increase surface area for improved heat dissipation.
- Material Options: Commonly constructed from copper or aluminum, chosen for their thermal conductivity.
- Coolant Flow Design: Engineered to ensure efficient coolant distribution, maximizing heat transfer without creating hot spots.
Benefits of Radiator Cold Plates
- Enhanced Cooling Efficiency: Provides consistent, uniform cooling across large surface areas.
- Reliability: Designed for high-power, continuous operation with minimal maintenance.
- Versatility: Can be tailored to work with various coolants, from water-based to more advanced dielectric coolants.
Applications
- Automotive Electronics: Effective cooling for EV power electronics and inverters.
- Telecommunications Equipment: Maintains stable temperatures in high-density power systems.
- Industrial Machinery: Suitable for systems requiring high, continuous power dissipation.

Gun-Drilled Cold Plates
Gun-drilled cold plates are constructed by creating deep, precisely drilled channels through a solid metal block, allowing coolant to flow directly through the plate. This method enables compact cooling solutions where tubing may not be feasible or desired.
Construction and Features
- Precision Drilled Channels: Channels are drilled to exact specifications for efficient coolant flow.
- Single-Piece Construction: Ideal for compact designs where space is limited, with no additional bonding required.
- High-Quality Materials: Copper and aluminum are commonly used for their thermal conductivity.
Benefits
- High Thermal Efficiency: Direct coolant contact with heat sources ensures effective heat transfer.
- Customization Options: Channels can be drilled in various patterns to suit specific cooling needs.
Applications
- Laser Cooling Systems: Keeps high-power laser components at stable temperatures within tight spaces.
- Power Converters & Inverters: Reliable cooling for compact electronics in automotive and industrial applications.
- Telecommunications: Ideal for small form-factor designs with high power density.
