Thermal Transfer Plate Heat Sink

Superior Heat Spreading: Phase-change thermal transfer plate uses a sealed vapor chamber to rapidly spread heat laterally across the base, reducing hotspots.

Ultra-High Thermal Conductivity: Offers dramatically lower thermal resistance than solid metal bases by leveraging vaporization and condensation cycles.

Compact Thin-Profile Design: Slim, planar structure ideal for applications with tight space constraints, enabling low-profile assemblies.

Passive and Reliable Operation: No pumps, fans, or moving parts required; liquid circulation is driven by capillary force in the wick structure.

Aluminum Alloy Construction: Built with lightweight yet thermally efficient aluminum alloys (e.g., 6063 or 6061) for performance and manufacturability.

Seamless Integration: Easily bonded to fin stacks-such as soldered or adhesive-attached arrays-to create high-efficiency heat sink assemblies.

Wide Thermal Range: Engineered to handle power dissipation from tens of watts up to multi-kilowatt loads with custom configurations.

Thermal Transfer Plate Heat Sink-FAQ's

What is a thermal transfer plate?

Itâ€™s a vapor chamber-based heat spreader that uses phase-change to distribute heat uniformly across the plate surface.

How does it improve thermal performance?

By spreading heat across a planar area, it reduces hotspots and lowers thermal resistance compared to solid bases.

Are moving parts required?

No-liquid circulation happens passively via capillary action inside the sealed chamber.

What materials are used?

Typically aluminum alloys such as 6063 or 6061, chosen for lightweight and thermal effectiveness.

How is it integrated with cooling fins?

Plates can be bonded or soldered to fin stacks, including zipper-fin configurations, for enhanced airflow dissipation.

What wick options are available?

Sintered, grooved, and mesh wick structures are provided depending on your thermal return and load needs.

Can size and shape be customized?

Yes-dimensions, thickness, and form factor can be tailored to your thermal design constraints.

Is engineering assistance offered?

Yes-thermal modeling, prototype iterations, and validation testing are part of our full support package.

Sinoextrud: Your Thermal Transfer Plate Heat Sink Manufacturer

Thermal transfer plate heat sinks employ the principles of vapor chamber cooling to deliver superior lateral heat spreading. By using evaporation and condensation inside a sealed chamber, heat is quickly redistributed, reducing temperature gradients and improving overall system performance.

The passive and robust design eliminates the need for external devices, allowing low-profile and lightweight thermal solutions. Aluminum construction ensures a cost-effective path to thermal management with good structural compatibility.

Plates can be seamlessly integrated with fin structures-whether soldered or bonded-to form high-performance assemblies. Finishes such as anodizing or custom coating extend durability and visual alignment with product design.

With custom sizing, multiple wick designs, and engineering support, our thermal transfer plates serve advanced thermal management roles across electronics, power modules, LED systems, and new energy devices, delivering both efficiency and reliability.
