The **ATS-18F-126-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 used by ATS to define the dimensions, fin style, and thermal properties. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. | | **Series** | pushPIN™ | | **Thermal Resistance** | 5.47°C/W (at 100 LFM) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) | | **Dimensions (L x W x H)** | 50.00mm x 50.00mm x 15.00mm | | **Fin Style** | Fine Pitch (Straight Fins) | --- ### 2. Physical Design Elements * **Heat Sink Material:** Constructed from high-grade aluminum. Aluminum is preferred in electronics for its excellent balance between thermal conductivity and weight. * **Fin Configuration:** The "Fine Pitch" design increases the total surface area. More surface area allows more heat to be transferred from the metal to the surrounding air. * **Blue Anodized Coating:** The blue finish is not just aesthetic; anodizing protects the aluminum from corrosion and slightly improves surface emissivity for radiant cooling. --- ### 3. Attachment Mechanism: pushPIN™ This specific model utilizes the **pushPIN™** system, which is a popular mounting solution in the industry for several reasons: 1. **Pre-assembled Spring:** It includes a flexible spring that provides precise pressure (clamped force) on the electronic chip, ensuring optimal thermal contact. 2. **Stability:** The push-pins go through pre-drilled holes in the PCB, making the heat sink secure against vibration and shock. 3. **Thermal Interface Material (TIM):** Most "R0" variants come with pre-applied **Phase Change Material** or thermal tape to bridge the microscopic gaps between the heat sink and the component. --- ### 4. Thermal Performance Comparison Thermal resistance is measured in °C/W (degrees Celsius per Watt). A lower number indicates better cooling performance. | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 LFM (Unducted) | 5.47 | | 200 LFM (Unducted) | 3.23 | | 400 LFM (Unducted) | 2.11 | --- ### 5. Common Applications * **Embedded Systems:** Industrial PCs and controllers. * **Telecommunications:** Network switches and routers. * **Power Supplies:** Cooling MOSFETs and voltage regulators. * **Consumer Electronics:** High-speed processors in custom hardware.
