The **ATS-08D-21-C2-R0** is a high-performance thermal management component, specifically a **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 hardware failure. --- ## 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal characteristics: | Property | Specification | Details | | :--- | :--- | :--- | | **Dimensions** | 60mm x 60mm | Large footprint for high-power chips | | **Height** | 10mm | Low profile for space-constrained enclosures | | **Material** | Aluminum | Lightweight with high thermal conductivity | | **Fin Style** | Straight Fin | Optimized for unidirectional airflow | | **Attachment** | Push-Pin | Secure mechanical mounting with springs | | **Interface Material** | T766 | High-performance Thermal Interface Material (TIM) | | **Finish** | Blue Anodized | Enhances emissivity and corrosion resistance | --- ## 2. Component Composition ### A. The Heat Sink Body The body is made of extruded aluminum. Aluminum is chosen for this part because it offers a balanced ratio between thermal conductivity (approx. 200 W/m·K) and weight. The "Straight Fin" design allows air to flow easily through the channels, making it ideal for systems with high-velocity fans. ### B. The Attachment Mechanism (push-pins) Unlike adhesive-based heat sinks, the **ATS-08D-21-C2-R0** uses a push-pin and spring system: * **Precision:** Ensures consistent pressure across the chip surface. * **Reliability:** Mechanical mounting is less likely to fail under high-vibration or high-heat environments compared to thermal tape. * **Hole Pattern:** Requires pre-drilled holes on the PCB (typically 3.0mm holes). ### C. Thermal Interface Material (TIM) The base comes pre-applied with **T766**. This is a phase-change or high-conductivity grease that fills microscopic air gaps between the component surface and the heat sink base, significantly reducing thermal resistance. --- ## 3. Performance Factors The efficiency of this part is measured by its **Thermal Resistance (θca)**. For this specific model: 1. **Passive Cooling:** Very high resistance (not recommended for high-load). 2. **Active Cooling:** At an airflow rate of 200 LFM (Linear Feet per Minute), the thermal resistance drops significantly, allowing the component to stay cool even under heavy computational loads. ---
