The **ATS-55330W-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "maxiFLOW™" series, specifically designed for cooling electronic components like processors, FPGAs, and ASICs in high-airflow environments. ### 1. Technical Specifications The following table summarizes the primary physical and thermal characteristics of the component: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | maxiFLOW™ | | **Part Number** | ATS-55330W-C2-R0 | | **Dimensions (L x W x H)** | 33.00mm x 33.00mm x 24.50mm | | **Material** | Aluminum (with Blue Anodized finish) | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Thermal Resistance** | 2.10 °C/W @ 200 LFM | | **Fin Style** | Spread Fin (Tapered) | --- ### 2. Key Electronic & Mechanical Design Features #### A. maxiFLOW™ Fin Geometry Unlike standard straight-fin heat sinks, the maxiFLOW™ design features a **tapered fin structure**. This geometry is engineered to: * Maximize surface area for heat dissipation. * Reduce pressure drop as air passes through the fins. * Increase airflow turbulence, which improves the heat transfer coefficient. #### B. maxiGRIP™ Attachment System The "C2" in the part number indicates the specific attachment mechanism. The **maxiGRIP™** system is a high-reliability mechanical solution that includes: 1. **Plastic Frame Clip:** This snaps around the perimeter of the electronic component (BGA/FPGA). 2. **Stainless Steel "X-Clip":** This fits over the heat sink and provides steady, even downward pressure. * *Advantage:* This method avoids the need to drill holes in the PCB and allows the heat sink to be removed and reattached easily for maintenance. #### C. Thermal Interface Material (TIM) The "R0" designation usually refers to the pre-applied Thermal Interface Material. * This heat sink typically comes with a high-performance **Phase Change Material (PCM)** or a thermal pad on the base. * This ensures that microscopic air gaps between the chip surface and the heat sink base are filled, facilitating efficient heat conduction. --- ### 3. Application Use Cases This specific model is used in electronics where space is constrained but thermal loads are high: * **Networking Equipment:** High-speed routers and switches. * **Telecommunications:** Base station power modules. * **Embedded Computing:** Industrial PC processors and high-performance graphics controllers.
