FSW Liquid Cold Plate Parts are advanced thermal management components manufactured using Friction Stir Welding (FSW) technology. Designed for high heat flux applications, these liquid cooling plates provide efficient and reliable heat dissipation for industries requiring stable thermal performance and long-term operational reliability.

FSW Liquid Cold Plate Parts are advanced thermal management components manufactured using Friction Stir Welding (FSW) technology. Designed for high heat flux applications, these liquid cooling plates provide efficient and reliable heat dissipation for industries requiring stable thermal performance and long-term operational reliability.

Compared with conventional brazed or bonded cooling plates, friction stir welded liquid cold plates offer superior mechanical strength, lower thermal resistance, and excellent leak-proof performance. The FSW process creates a solid-state weld without melting the base material, resulting in a highly durable and defect-free cooling structure.

KINGKA provides custom FSW liquid cold plate parts tailored to customer thermal requirements, including cooling channel design, material selection, size customization, and surface treatment. These liquid cooling solutions are widely used in battery cooling systems, power electronics, EV thermal management, data centers, and industrial equipment.

FSW Liquid Cold Plate Parts

What Is FSW Liquid Cold Plate?

An FSW Liquid Cold Plate is a type of liquid cooling plate fabricated using Friction Stir Welding technology to seal internal coolant channels within a metal plate, typically aluminum.

The cold plate works by circulating coolant through precisely designed flow channels. Heat generated by electronic devices or power modules transfers to the metal plate and is rapidly removed by the flowing coolant.

Unlike traditional fusion welding methods, FSW produces a solid-state joint through frictional heat and material plastic deformation, minimizing porosity, distortion, and leakage risks.

As a result, FSW liquid cold plate parts are ideal for applications requiring:

  • High heat transfer efficiency

  • Reliable coolant sealing

  • Lightweight construction

  • High structural integrity

  • Long service life

  • Stable cooling under demanding conditions


How FSW Liquid Cold Plate Parts Work

Liquid Cooling Working Principle

FSW liquid cold plate cooling relies on conductive and convective heat transfer.

The cooling process typically follows these steps:

1. Heat Generation

Electronic components, batteries, or power modules generate heat during operation.

2. Heat Conduction

Heat transfers from the heat source into the thermal interface material and then into the aluminum liquid cold plate.

3. Coolant Circulation

Coolant such as water or glycol flows through internal channels engineered inside the cold plate.

4. Heat Exchange

The coolant absorbs heat from the plate surface and carries it away toward an external heat exchanger or radiator.

5. Continuous Thermal Regulation

The cooling cycle repeats continuously to maintain safe operating temperatures and stable equipment performance.

Because FSW cold plate cooling creates highly sealed and uniform flow channels, coolant circulation remains efficient while minimizing pressure loss and leakage risk.


Why Use Friction Stir Welding for Liquid Cold Plates?

Friction Stir Welding has become one of the most advanced joining technologies for liquid cooling systems.

Unlike brazing or traditional welding, FSW uses a rotating tool that generates frictional heat and plastically joins the material without melting it.

This process offers several advantages.

Superior Leak Resistance

The solid-state welding structure creates highly reliable sealed channels, significantly reducing coolant leakage risk.

Lower Thermal Resistance

FSW produces intimate material bonding with minimal voids, improving thermal conductivity and heat transfer efficiency.

Minimal Distortion

Because melting is avoided, the process reduces thermal deformation and preserves dimensional accuracy.

Higher Mechanical Strength

The welded joint maintains excellent structural integrity under vibration, pressure, and thermal cycling.

Cleaner Manufacturing

FSW does not require filler materials or flux, reducing contamination and supporting cleaner production.

These benefits make friction stir welded cold plates particularly suitable for high-power and mission-critical cooling systems.
