The **ATS-16H-159-C2-R0** is a high-performance electronic 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. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions (L x W x H)** | 45mm x 45mm x 10mm | | **Thermal Resistance** | 10.71°C/W (Unducted Flow @ 100 LFM) | | **Fin Style** | XC (Cross-Cut) | | **TIM (Thermal Interface Material)** | T766 (Pre-applied) | --- ### 2. Key Components & Design Features #### A. Fin Design (XC - Cross-Cut) The "XC" designation indicates a **cross-cut fin pattern**. Unlike straight fins, cross-cut fins allow for multi-directional airflow. This is critical in cramped electronic enclosures where airflow might not be perfectly linear. #### B. pushPIN™ Attachment This model uses the proprietary **pushPIN™** system. It consists of: * **Compression Springs:** Provide precise pressure to ensure optimal contact with the heat source. * **Plastic/Brass Pins:** Secure the heat sink through pre-drilled holes in the PCB. * **Reliability:** This method is preferred over adhesive tapes for high-vibration environments. #### C. Thermal Interface Material (TIM) The unit comes with **T766** pre-applied to the base. This is a high-conductivity material that fills microscopic air gaps between the component surface and the heat sink base, significantly improving heat transfer efficiency. --- ### 3. Thermal Performance Profile Thermal resistance determines how effectively the heat sink removes heat. The performance improves as the airflow (Measured in Linear Feet per Minute - LFM) increases. | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 10.71 | | 300 (1.5 m/s) | 4.45 | | 500 (2.5 m/s) | 3.19 | | 700 (3.5 m/s) | 2.59 | --- ### 4. Applications * **Embedded Systems:** Cooling processors in industrial computers. * **Networking Gear:** Heat dissipation for ASICs in routers and switches. * **Power Supplies:** Cooling voltage regulators and MOSFETs. ---
