The **ATS-19B-60-C2-R0** is a specific high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "maxiFLOW" series, designed for cooling electronic components such as CPUs, GPUs, FPGAs, and ASICs. --- ## 1. Technical Specifications Below are the primary electronic and physical specifications for this component: | Feature | Specification | | :--- | :--- | | **Part Number** | ATS-19B-60-C2-R0 | | **Thermal Resistance** | 1.45° C/W (at 200 LFM) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ | | **Dimensions (L x W x H)** | 45mm x 45mm x 25mm | | **Fin Style** | maxiFLOW (Tapered Fin) | | **Pressure Requirement** | 0.81 in-H2O (at 200 LFM) | --- ## 2. Key Design Features ### A. maxiFLOW™ Fin Geometry The "maxiFLOW" design uses a tapered fin structure. This is critical for electronic systems because it increases the surface area while maintaining a low pressure drop. This allows for maximum heat dissipation even in systems with restricted airflow. ### B. pushPIN™ Attachment Instead of using messy thermal adhesives or simple clips, this model uses a **pushPIN™** mechanism. * **Reliability:** Ensures consistent pressure across the interface of the chip. * **Assembly:** Features a flexible, high-performance compression spring. * **Stability:** Prevents the heat sink from shifting during vibration or shipping. ### C. Material and Finish * **Aluminum:** Chosen for its balance between thermal conductivity and weight. * **Blue Anodized:** The coating protects against corrosion and improves surface emissivity, aiding slightly in radiative heat transfer. --- ## 3. Thermal Performance Analysis Electronic parts like the ATS-19B-60-C2-R0 are rated based on **LFM (Linear Feet per Minute)** airflow. | Airflow (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 200 | 1.45 | | 300 | 1.15 | | 400 | 0.98 | | 500 | 0.86 | --- ## 4. Usage Considerations When integrating this part into an electronic design, engineers must account for: 1. **TIM (Thermal Interface Material):** This part usually comes with pre-applied **ATS-54** phase-change material or similar, which fills microscopic air gaps between the chip and the heat sink. 2. **Component Clearance:** The 25mm height must fit within the chassis (1U, 2U, etc.). 3. **Hole Pattern:** The PCB must be pre-drilled to match the specific pushPIN™ spacing for this model.
