The **ATS-18F-197-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) | | **Series** | pushPIN™ HS Assembly | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) | | **Thermal Resistance (Unducted)** | 10.90 °C/W @ 100 LFM | | **Thermal Resistance (Ducted)** | 3.56 °C/W @ 100 LFM | | **Dimensions (L x W)** | 45mm x 45mm | | **Height** | 10mm | --- ### 2. Physical Design and Construction * **Fin Profile (Cylindrical):** This model uses a **cross-cut** or "Pin Fin" design. This allows for multi-directional airflow, making it ideal for systems where the direction of the cooling air is not strictly horizontal or vertical. * **Base Plate:** A flat aluminum base that makes direct contact with the electronic component (IC). * **Push-Pin Mounting:** Unlike adhesive-based heat sinks, this uses a spring-loaded push-pin mechanism. * **Advantage:** Provides consistent downward pressure for better thermal interface contact. * **Reliability:** It is more secure against mechanical shocks and vibrations compared to thermal tape. --- ### 3. Thermal Performance Analysis The efficiency of this part is measured by its **Thermal Resistance**. A lower number indicates better heat dissipation. * **Natural Convection:** Without a fan, the resistance is high (10.90 °C/W). * **Forced Convection:** In a chassis with high-speed fans (e.g., 700 LFM), the resistance drops significantly (approx. 1.81 °C/W), allowing it to handle much higher TDP (Thermal Design Power) components. --- ### 4. Application and Use-Cases 1. **Network Switches/Routers:** Ideal for high-speed processors in cramped network enclosures. 2. **Embedded Systems:** Used on SoCs (System on Chips) where height is restricted (only 10mm tall). 3. **Power Electronics:** Dissipating heat from MOSFETs or voltage regulators.
