Radiator-Integrated Liquid Cooling Plate

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.

I. Structural Features

Bonding Surface (Cold Plate Side)

Flat surface that directly attaches to IGBTs, power modules, batteries, motors and other heat-generating components.

Fin Heat Dissipation Side (Radiator Side)

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.

Fully Integrated Structure

Mostly manufactured as one piece through skiving, die-casting or brazing,

eliminating the complex assembly of separate radiators and water tubes.

II. Working Principle

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.

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.
