## ATS-54170D-C1-R0: High-Performance Heat Sink Analysis The **ATS-54170D-C1-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "maxiFLOW™" series, designed specifically for cooling high-heat-generating electronic components such as CPUs, GPUs, FPGAs, and ASICs. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Part Number** | ATS-54170D-C1-R0 | | **Series** | maxiFLOW™ | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Material** | Aluminum (Body) / Copper (optional base available in some variants) | | **Finish** | Blue Anodized | | **Thermal Resistance** | 2.50 °C/W (at 200 LFM) | | **Dimensions (L x W x H)** | 54.00mm x 54.00mm x 9.50mm | --- ### 2. Component Design Features #### A. maxiFLOW™ Fin Geometry Unlike standard square-cut heat sinks, the maxiFLOW™ design uses tapered fins. This geometry is engineered to: * **Increase Surface Area:** More area for heat dissipation relative to the footprint. * **Optimize Airflow:** Reduce pressure drop, allowing air to move more freely through the fins, which is critical in high-density electronic enclosures. #### B. maxiGRIP™ Attachment System One of the most significant "parts" of this assembly is the attachment mechanism. It avoids the need for drilling holes in the PCB: * **Plastic Frame Clip:** A high-temperature plastic frame that snaps around the component. * **Stainless Steel Spring Clip:** Provides steady, even pressure (preload) across the component surface to ensure optimal thermal contact. #### C. Thermal Interface Material (TIM) The "C1" in the part number indicates that the unit comes pre-applied with **Chomerics T766** phase-change material or a high-performance thermal tape. This eliminates the need for manual thermal paste application and ensures low thermal resistance between the component and the sink. --- ### 3. Application Use-Cases The ATS-54170D-C1-R0 is typically found in the following electronic environments: 1. **Telecommunications:** Cooling high-speed switching chips. 2. **Embedded Systems:** Industrial PCs where vertical space (9.5mm height) is limited. 3. **Networking Hardware:** Routers and gateways requiring reliable passive or semi-active cooling. --- ### 4.
