SINBO Precision Mechanical Co., Ltd, based in Dongguan, has emerged as a leading player in this field, renowned for its top-notch custom precision mechanical components. Among its diverse range of offerings, the processing of aluminum microchannel heat sinks has been a particular area of expertise, catering to the needs of various industries. The Challenge: Meeting Stringent Heat Dissipation Requirements One of SINBO Precision's clients, a prominent company in the electronics industry, was in the process of developing a new generation of high-performance electronic devices. These devices were designed to operate at high frequencies, generating a substantial amount of heat during operation. To ensure their stable and reliable performance, an advanced heat sink design was required. The challenge was twofold: first, to create an aluminum microchannel heat sink that could effectively dissipate the large amounts of heat generated; second, to achieve this while maintaining the highest standards of precision and quality, as even the slightest deviation could lead to compromised heat dissipation and device failure. SINBO Precision's Solution Material Selection SINBO Precision began by carefully selecting the material for the heat sink. After comprehensive research and analysis, they opted for high-quality 6063 T5 aluminum alloy. This material was chosen for several reasons. Firstly, aluminum is known for its excellent thermal conductivity, which is essential for efficient heat transfer. The 6063 T5 alloy, in particular, has a thermal conductivity of approximately 160 - 180 W/m.K, making it a suitable choice for heat sink applications. Secondly, aluminum is relatively soft and easy to process, which is beneficial for achieving the complex microchannel structures required. Additionally, it is cost-effective, making it an ideal material for mass production. The high purity of the 6063 T5 aluminum alloy, reaching over 98%, further enhanced its performance, ensuring reliable heat dissipation. Advanced Processing Techniques ** Extrusion The manufacturing process commenced with the extrusion of the aluminum alloy. The aluminum ingots were heated to a high temperature, typically around 520 - 540 °C. At this elevated temperature, the aluminum became malleable and was then forced through a specially designed extrusion die under high pressure. This process shaped the aluminum into a rod with the basic form of the heat sink. The extrusion process at SINBO Precision was carried out using state-of-the-art extrusion equipment, which allowed for precise control over the dimensions and quality of the extruded product. This ensured that the microchannel heat sink embryos had consistent and accurate dimensions, laying the foundation for the subsequent processing steps. Molding Once the aluminum rod was extruded, it was injected into a grooved mold. This mold was meticulously designed to create the intricate microchannel patterns that are characteristic of high-performance heat sinks. The molding process was crucial as it determined the final shape and structure of the microchannels, which play a vital role in enhancing heat transfer. By injecting the aluminum into the mold, SINBO Precision was able to achieve the desired microchannel geometry with high precision, ensuring optimal heat dissipation performance. Subsequent Processing CNC Machining: To further refine the shape and dimensions of the heat sink, SINBO Precision employed Computer Numerical Control (CNC) machining. This advanced machining technique enabled the company to create complex features with micron-level precision. The CNC machines were programmed to perform a series of operations, such as milling, turning, and drilling, to shape the heat sink according to the client's specifications. For example, the microchannels were machined to have smooth walls and precise dimensions, which improved the flow of coolant or air through them, enhancing heat transfer efficiency. Trimming, Drilling, and Tapping: After CNC machining, the heat sinks underwent trimming to remove any excess material and ensure clean edges. Drilling operations were carried out to create holes for mounting the heat sink onto the electronic device. Tapping was also performed to create internal threads, allowing for the use of screws or bolts for secure fastening. These operations were carried out with great precision to ensure that the heat sink could be easily integrated into the client's product. Polishing and Wire Drawing: To enhance the aesthetic appearance and heat transfer performance of the heat sink, polishing and wire drawing processes were applied. Polishing the surface of the heat sink made it smoother, reducing the resistance to the flow of coolant or air. Wire drawing, on the other hand, created a uniform texture on the surface, increasing the surface area available for heat transfer. These surface treatments not only improved the heat dissipation capabilities of the heat sink but also gave it a more professional and appealing look. Surface Treatment: A suitable surface treatment was then applied to the heat sink. Anodizing was chosen as the surface treatment method in this case. Anodizing involves creating a thick, protective oxide layer on the surface of the aluminum through an electrochemical process. This oxide layer not only provided excellent corrosion resistance but also enhanced the heat transfer coefficient. The anodized surface was also more durable and scratch-resistant, ensuring the long-term performance of the heat sink. Riveting Pin and Packaging: Finally, riveting pins were added to the heat sink for secure assembly. These pins provided additional strength and stability to the heat sink, ensuring that it could withstand the rigors of use. Once all the manufacturing processes were complete, the heat sinks were carefully packaged to prevent any damage during transportation. The packaging materials were chosen to provide adequate protection while also being environmentally friendly. The Results The aluminum microchannel heat sink processed by SINBO Precision successfully met the client's stringent thermal performance requirements. The innovative design and advanced processing techniques resulted in a heat sink with exceptional heat dissipation capabilities. The microchannel structure, combined with the high thermal conductivity of the 6063 T5 aluminum alloy, allowed for efficient heat transfer from the electronic device to the surrounding environment. This significantly reduced the operating temperature of the device, improving its performance, reliability, and lifespan. Moreover, SINBO Precision's commitment to quality control was evident throughout the manufacturing process.
