## Technical Overview of ATS-16H-147-C2-R0 The **ATS-16H-147-C2-R0** is a high-performance **Heat Sink** assembly designed by Advanced Thermal Solutions (ATS). It is part of the "push pin" attachment series, specifically engineered for cooling electronic components such as CPUs, GPUs, or high-power semiconductors. --- ### 1. Key Technical Specifications Below are the primary physical and thermal characteristics of the component: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum (Blue Anodized) | | **Attachment Method** | Push-Pin (Brass/Plastic) | | **Dimensions** | 35mm x 35mm x 10mm | | **Fin Style** | Straight Fin | | **Thermal Resistance** | 13.52°C/W (@ 1.0 m/s airflow) | | **TIM (Interface Material)** | T766 (High Performance) | --- ### 2. Component Analysis #### A. The Fin Design (Straight Fin) The "Straight Fin" design is optimized for environments with **forced air cooling**. Unlike cross-cut fins, straight fins offer lower pressure drop, making them efficient when the airflow direction is consistent across the PCB. #### B. Thermal Interface Material (T766) The part comes pre-applied with **T766 thermal grease**. This is a phase-change material that ensures a low-resistance path between the heat source (chip) and the aluminum heat sink, eliminating air gaps. #### C. Mounting Mechanism (Push-Pin) This model utilizes a push-pin system with a compression spring. * **Benefits:** Ensures consistent downward pressure (load) on the component. * **Security:** Prevents the heat sink from shifting during vibration or shipping. * **Requirement:** The PCB must have pre-drilled holes at specific intervals to accept the pins. --- ### 3. Thermal Performance Data Thermal resistance ($\theta$) determines how efficiently heat is dissipated. Lower values are better. | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | **200 (1.0 m/s)** | 13.52 | | **400 (2.0 m/s)** | 7.55 | | **600 (3.0 m/s)** | 5.48 | | **800 (4.0 m/s)** | 4.61 | --- ### 4. Part Number Breakdown The part number follows a specific ATS nomenclature: * **ATS:** Manufacturer prefix. * **16H:** Height code (10mm). * **147:** Specific footprint/model identifier. * **C2:** Material/Finish (Blue Anodized Aluminum). * **R0:** Revision or RoHS compliance status.
