The **ATS-08F-79-C2-R0** is a high-performance thermal management component, specifically an **Aluminum Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic components like CPUs, GPUs, or power transistors to prevent thermal throttling or failure. --- ## 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal characteristics. | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Lightweight and good thermal conductivity) | | **Finish** | Blue Anodized (Corrosion resistance and improved emissivity) | | **Dimensions (L x W x H)** | 25mm x 25mm x 30mm | | **Attachment Method** | **push-pin** (Plastic pins with springs) | | **Thermal Resistance** | ~2.63 °C/W (at 200 LFM airflow) | | **Fin Type** | XC-CUT (Cross-cut fins for multi-directional airflow) | --- ## 2. Key Components & Design The ATS-08F-79-C2-R0 is engineered for specific airflow environments: ### A. Fin Geometry (XC-CUT) Unlike straight-fin heat sinks, the "XC-CUT" design features rectangular blocks. This allows the heat sink to perform effectively regardless of the direction of the cooling fan's airflow, making it ideal for crowded PCB layouts. ### B. Attachment Mechanism (Push-Pin) * **Spring-Loaded:** The push-pins utilize a brass or plastic spring to provide constant pressure on the electronic chip. * **Stability:** This ensures the thermal interface material (TIM) remains compressed, minimizing the air gap between the chip and the heat sink. ### C. Thermal Interface Material (TIM) Most "R0" variants come pre-applied with a high-performance **Phase Change Material** (typically ATS-51) on the base. This material melts at operating temperatures to fill microscopic surface irregularities. --- ## 3. Performance Analysis Thermal performance is highly dependent on the **Air Velocity** (measured in Linear Feet per Minute - LFM): | Airflow (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | **200 LFM** | 2.63 | | **300 LFM** | 2.14 | | **400 LFM** | 1.90 | *Note: Lower °C/W values indicate better cooling efficiency.* --- ## 4. Typical Applications * **Embedded Systems:** Cooling small-form-factor processors. * **Telecommunications:** Network switches and routers. * **Power Supplies:** Heat dissipation for MOSFETs and voltage regulators. * **Industrial Controls:** High-heat environments requiring passive or semi-passive cooling.
