The **ATS-20F-202-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "pushPIN™" series, designed specifically for cooling electronic components like CPUs, GPUs, or power transistors that generate significant heat in confined spaces. --- ## 1. Key Specifications The technical properties of this specific model are detailed in the table below: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Part Number** | ATS-20F-202-C2-R0 | | **Material** | Aluminum (AL6063) | | **Fin Type** | Straight Fin | | **Attachment Method** | pushPIN™ (Spring-loaded pins) | | **Dimensions (LxWxH)** | 54.00 mm x 54.00 mm x 10.00 mm | | **Thermal Resistance** | 14.83 °C/W (Unducted Flow @ 100 LFM) | | **Finish** | Blue Anodized | | **Thermal Interface** | T766 (Pre-applied Phase Change Material) | --- ## 2. Component Breakdown ### A. The Heat Sink Body The unit is made from **Aluminum 6063**, which offers a high thermal conductivity-to-weight ratio. The **Straight Fin** design is optimized for environments where there is a consistent directional airflow (ducted or unducted). ### B. The pushPIN™ Attachment System Instead of using messy adhesives or permanent solder, this part uses a mechanical push-pin system. * **Ease of Use:** Allows for quick installation and removal. * **Constant Pressure:** The springs ensure even pressure across the component surface, maximizing heat transfer. ### C. Thermal Interface Material (TIM) The "C2" in the part number indicates the use of **T766** thermal material. This is a high-performance phase-change material that fills microscopic air gaps between the heat sink and the electronic chip to reduce thermal resistance. ### D. Finish (Blue Anodized) The blue anodized coating is not just for aesthetics; it provides: 1. **Corrosion Resistance:** Protects the aluminum from oxidation. 2. **Increased Emissivity:** Slightly improves heat dissipation through radiation. --- ## 3. Performance Metrics Thermal resistance indicates how effectively the part moves heat away from the component. | Airflow Velocity (LFM) | 100 (0.5m/s) | 200 (1.0m/s) | 300 (1.5m/s) | 400 (2.0m/s) | | :--- | :--- | :--- | :--- | :--- | | **Unducted (°C/W)** | 14.83 | 6.91 | 5.31 | 4.44 | | **Ducted (°C/W)** | 5.23 | 3.90 | 3.28 | 2.88 | ---
