### Technical Overview: ATS-18F-191-C2-R0 The **ATS-18F-191-C2-R0** is a high-performance **heat sink** manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "push pin" series, designed specifically to dissipate heat from electronic components such as processors, GPUs, and power modules. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum (Blue Anodized) | | **Attachment Method** | Push Pin (Plastic) | | **Fin Style** | Straight Fin | | **Thermal Resistance** | 2.90°C/W @ 200 LFM | | **Dimensions** | 45.00mm x 45.00mm x 30.00mm | | **Spring Type** | Brass | | **Interface Material** | T766 (Thermal Interface Material) | --- ### 2. Major Components and Design #### A. The Heat Sink Body * **Material:** Constructed from high-grade aluminum. The **Blue Anodized** finish is not just for aesthetics; it provides surface protection and slightly improves radiation heat transfer. * **Fin Geometry:** It features a "Straight Fin" design. This is optimized for **forced air convection** (where a fan is blowing air across the heatsink). #### B. The Mounting Mechanism (Push Pins) * **Push Pins:** These are pre-assembled plastic pins that snap into pre-drilled holes on the PCB. * **Compression Springs:** The "R0" designation refers to a specific spring tension. These springs ensure consistent pressure between the heat sink and the chip, which is critical for minimizing thermal resistance. #### C. Thermal Interface Material (TIM) * **T766:** The unit comes with a pre-applied thermal pad or grease (T766). This fills the microscopic air gaps between the component and the heat sink base, significantly improving heat conduction. --- ### 3. Thermal Performance Matrix Thermal resistance indicates how effectively the part moves heat away. Lower values are better. | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | **200 (1.0 m/s)** | 2.90 | | **400 (2.0 m/s)** | 1.88 | | **600 (3.0 m/s)** | 1.48 | --- ### 4. Application Use-Cases * **BGA Packaging:** Ideal for Ball Grid Array chips that generate significant heat. * **Networking Equipment:** Switches and routers where airflow is controlled. * **Industrial PCs:** High-reliability environments requiring secure physical mounting (push pins are more vibration-resistant than adhesive tape).
