Radiator-Integrated Liquid Cooling Plate

I. Structural Features

Bonding Surface (Cold Plate Side)

Fin Heat Dissipation Side (Radiator Side)

Fully Integrated Structure

II. Working Principle

1. Heat from components → conducts to the liquid cooling plate base
2. Coolant flows through internal channels and absorbs heat
3. Heated coolant flows into the finned radiator section
4. Fins release heat into the environment via fans or natural airflow
5. Cooled coolant circulates back to repeat the process

III. Core Advantages

• Compact structure & high integration

   

  All-in-one design saves space, reduces connectors and leakage points.
   
• Simple installation

   

  Directly mounted to components; only an external pump and reservoir are needed, no extra radiator required.
   
• Uniform heat dissipation

   

  Excellent temperature uniformity on the base plate, avoiding local hotspots.
   
• High reliability

   

  Brazed or skived structure provides strong vibration resistance, ideal for automotive and industrial control applications.
   

IV. Common Manufacturing Processes

• Skived Radiator-Integrated Liquid Cooling Plate

   

  Fins and flow channels machined from a single aluminum block, offering high strength and continuous thermal conductivity.
   
• Vacuum Brazed Type

   

  Base plate and fins joined by brazing, with denser fins and larger heat dissipation area.
   
• Integral Die-Casting Type

   

  Suitable for mass production and low cost, widely used in passenger vehicle thermal management.
   

V. Typical Applications

• New energy vehicles: integrated cooling for motors, ECU, OBC, DC-DC converters
• Energy storage converters (PCS), photovoltaic inverters
• Industrial servo drives, high-power power supplies
• Laser equipment, welding machines, high-frequency power supplies
• Construction machinery, commercial vehicle controller cooling

VI. Difference from Standard Liquid Cooling Plates

• Standard liquid cooling plate: only absorbs and transfers heat; does not dissipate heat directly to the environment.
• Radiator-integrated liquid cooling plate: absorbs heat, circulates internally, and dissipates heat via its own fins, forming a complete compact cooling system.
