The Challenge: Meeting Stringent Heat Dissipation Requirements

One of SINBO Precision's clients, a leading company in the electronics industry, was developing a new generation of high-performance electronic devices. These devices required an advanced heat sink design to effectively dissipate the large amounts of heat generated during operation. The challenge was to create an aluminum microchannel heat sink that could meet the strict thermal performance requirements while maintaining high precision and quality.

SINBO Precision's Solution

Material Selection

SINBO Precision opted for high-quality 6063 T5 aluminum alloy. This material is renowned for its high purity, reaching over 98%, which makes it an ideal choice for heat sink applications. Aluminum is soft, easy to process, and cost-effective, while the 6063 T5 alloy offers enhanced mechanical properties, ensuring the durability of the heat sink.

Advanced Processing Techniques

1. Extrusion

The manufacturing process began with heating the aluminum ingot to a high temperature and extruding it into an aluminum rod. This initial step is crucial as it forms the basic shape of the heat sink. The extrusion process at SINBO Precision is carried out using state-of-the-art equipment, ensuring consistent quality and dimensional accuracy.

1. Molding

The extruded aluminum rod was then injected into a grooved mold to create the primary embryo of the aluminum microchannel heat sink. This mold was specifically designed to achieve the intricate microchannel patterns required for optimal heat transfer.

1. Subsequent Processing
• CNC Machining: SINBO Precision utilized Computer Numerical Control (CNC) machining to further refine the shape and dimensions of the heat sink. This high-precision process allowed for the creation of complex features, such as precise channels and smooth surfaces, which are essential for efficient heat dissipation.
• Trimming, Drilling, and Tapping: These processes were carried out to create the necessary holes and threads for mounting and assembly purposes. The precision of these operations ensured a perfect fit with other components in the electronic device.
• Polishing and Wire Drawing: To enhance the aesthetic appearance and heat transfer efficiency, the heat sink underwent polishing and wire drawing processes. These treatments not only made the surface smoother but also increased the surface area available for heat transfer.
• Surface Treatment: A suitable surface treatment was applied to improve the corrosion resistance and heat dissipation performance of the heat sink. Anodizing, for example, was used to create a hard, protective oxide layer on the aluminum surface, which also enhanced the heat transfer coefficient.
• Riveting Pin and Packaging: Finally, riveting pins were added for secure assembly, and the heat sink was carefully packaged to prevent any damage during transportation.

The Results

The aluminum microchannel heat sink processed by SINBO Precision successfully met the client's thermal performance requirements. The innovative design and advanced processing techniques resulted in a heat sink with excellent heat dissipation capabilities. The microchannel structure allowed for efficient heat transfer, reducing the operating temperature of the electronic device significantly. This, in turn, improved the device's performance, reliability, and lifespan.

Moreover, SINBO Precision's commitment to quality control ensured that each heat sink met the highest standards. The company's strict inspection procedures at every stage of the manufacturing process guaranteed that the heat sinks were free from defects and met the client's specifications precisely.
