Features of Thermal Solution

High Thermal Conductivity

Thermal Solution uses a copper base with aluminum fins or a liquid cooling structure. The copper base quickly absorbs and transfers heat, making it suitable for continuous cooling of high-power devices.

Liquid Cooling Performance

The liquid cooling plate is made with an aluminum plate + copper tube structure and FSW welding. It provides around 200W cooling capacity and handles high loads steadily.

Surface Protection Performance

With anodizing or coating, it helps reduce oxidation and corrosion, and the service life is about 3–5 years.

Multi-Structure Compatibility

It can be used together with heat pipes, vapor chambers, and liquid cooling modules to cool multiple heat sources at the same time.

Quality Control

01/

Raw Material Selection & Inspection
We screen raw materials—such as aluminum and copper—based on their chemical composition and thermal conductivity to ensure that the base materials meet the specific requirements for both thermal dissipation and structural integrity.

02/

Production Process Control
We strictly monitor and control key process parameters during CNC machining, forming, and assembly stages to guarantee structural stability and consistent thermal dissipation performance.

03/

Dimensional Accuracy Testing
We utilize calipers, micrometers, and Coordinate Measuring Machines (CMM) to verify dimensions, maintaining a strict tolerance control within ±0.02mm.

04/

Surface Quality Inspection
We inspect surface treatments—such as anodizing and sandblasting—to verify their visual appearance and coating uniformity, ensuring the integrity of the protective layer.

05/

Liquid Cooling Structure Check
We conduct sealing and structural inspections on liquid cooling channels and interfaces to ensure channel integrity and eliminate any risk of leakage.

06/

Final Inspection & Traceability
Prior to shipment, we perform a final inspection of the product's appearance and structure, and maintain batch traceability records to facilitate future management and reference.

FAQ

Q: How does a Thermal Solution work?

A: A Thermal Solution transfers heat from a heat source to a heat dissipation structure using thermally conductive materials, and then utilizes air or liquid media to carry the heat away, thereby achieving temperature reduction.

Q: In which devices are these solutions primarily used?

A: They are widely applied in high-heat-generating systems such as power modules, servers, LED lighting, and industrial control equipment.

Q: How is heat conduction achieved?

A: Heat is rapidly absorbed using a copper base or heat pipes, and is then dissipated through aluminum fins, which also serve to increase the heat dissipation surface area.

Q: What are the available installation methods for Thermal Solutions?

A: They support various installation methods—including screw fastening, clip-mounting, and press-fitting—to accommodate the specific structural installation requirements of different devices.

Q: How should routine maintenance be performed?

A: It is necessary to keep the heat dissipation surfaces clean; avoid dust accumulation, as this can impede airflow and compromise cooling efficiency.
