Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions, Inc. (ATS) | | **Part Number** | ATS-11D-161-C2-R0 | | **Material** | Aluminum (Body), Blue Anodized (Finish) | | **Attachment Type** | pushPIN™ (Spring-loaded) | | **Dimensions** | 45mm x 45mm x 20mm | | **Thermal Resistance** | 4.74°C/W (Unducted Flow @ 100 LFM) | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Major Component Parts The assembly consists of four primary electronic/mechanical parts that work together to provide cooling and stability: #### A. The Heat Sink Body * **Material:** Extruded Aluminum. * **Design:** Features a "Fine Pitch" or "Cross-Cut" fin pattern to maximize surface area for heat dissipation. * **Function:** Conducts heat away from the semiconductor die through the base and into the air via the fins. #### B. The pushPIN™ Attachment Mechanism * **Components:** A plastic or metal pin with a compressed spring. * **Function:** Provides consistent pressure (clamping force) on the electronic component. This ensures the thermal interface material is thin and effective, reducing thermal resistance. #### C. Thermal Interface Material (TIM) * **Type:** T766 (Phase change or high-performance grease). * **Function:** Fills the microscopic air gaps between the heat sink base and the electronic chip (the heat source). Air is a poor conductor, so the TIM is critical for efficient heat transfer. #### D. The Finish (Blue Anodized) * **Function:** While primarily for aesthetics and corrosion resistance, the anodized layer also slightly improves the surface emissivity for radiation cooling. --- ### 3. Performance Metrics The effectiveness of this part depends heavily on the airflow (LFM - Linear Feet per Minute): | Airflow (LFM) | Velocity (m/s) | Thermal Resistance (°C/W) | | :--- | :--- | :--- | | 100 | 0.5 | 4.74 | | 300 | 1.5 | 2.57 | | 500 | 2.5 | 2.02 | --- ### 4. Application Use Case This part is typically used in: * **Networking Equipment:** Routers and switches. * **Industrial PCs:** Compact systems requiring passive or active airflow cooling. * **Power Supplies:** Cooling MOSFETs or power regulators. ---
