Integrated Liquid Cooling Cold Plate Radiator Heat Dissipation Fin Solution
In simple terms: Radiator-Integrated Liquid Cooling Plate = Liquid cooling plate + integrated heat dissipation fins
It attaches to heat-generating devices on one side and features dense fins on the other. Heat is transferred to the fin area via coolant circulation, forming a compact, all-in-one liquid cooling solution.
Flat surface that directly attaches to IGBTs, power modules, batteries, motors and other heat-generating components.
Internal flow channels extend into the dense fin region, forming a structure similar to a radiator.
As coolant flows through, heat is carried to the fins and dissipated via air cooling or natural convection.
Mostly manufactured as one piece through skiving, die-casting or brazing, eliminating the complex assembly of separate radiators and water tubes.
- Heat from components → conducts to the liquid cooling plate base
- Coolant flows through internal channels and absorbs heat
- Heated coolant flows into the finned radiator section
- Fins release heat into the environment via fans or natural airflow
- Cooled coolant circulates back to repeat the process
It is a hybrid solution combining liquid cooling heat transfer and air cooling final dissipation.
All-in-one design saves space, reduces connectors and leakage points.
Directly mounted to components; only an external pump and reservoir are needed, no extra radiator required.
Excellent temperature uniformity on the base plate, avoiding local hotspots.
Brazed or skived structure provides strong vibration resistance, ideal for automotive and industrial control applications.
- 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.
- 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
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.
