The **ATS-18B-127-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 failure. --- ## 1. Technical Specifications The part number follows a specific nomenclature used by ATS to define the dimensions, fin style, and material properties. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ Heat Sink Assembly | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Thermal Resistance** | 3.84°C/W (at 100 LFM) | | **Attachment Method** | Push-pin (Plastic or Brass) | | **Base Dimensions** | 54.00 mm x 54.00 mm | | **Height** | 20.00 mm | | **Compression Spring** | ATS-PPS-18 | --- ## 2. Component Breakdown The assembly consists of three primary electronic packaging elements: ### A. The Heat Sink Body * **Design:** It utilizes a **cross-cut** or **straight-fin** design (part of the "mini-fan" or "high-flow" series), providing a large surface area for convective cooling. * **Material:** Made of high-grade aluminum for high thermal conductivity while remaining lightweight. * **Anodization:** The "Blue Anodized" finish isn't just for aesthetics; it provides corrosion resistance and increases surface emissivity, slightly improving radiation cooling. ### B. The Attachment Mechanism (Push-Pin) * The "18B" designation refers to the specific hardware kit. * It uses a **spring-loaded push-pin** system. This ensures consistent "Interface Pressure" between the heat sink and the electronic chip, which is critical for minimizing thermal contact resistance. ### C. Thermal Interface Material (TIM) * **Pre-applied:** The "C2" indicates the type of thermal interface material (usually a high-performance thermal pad or phase-change material) pre-applied to the base. * **Function:** It fills microscopic air gaps between the component die and the heat sink base to ensure efficient heat transfer. --- ## 3. Thermal Performance Metrics The effectiveness of this part depends on the airflow (measured in Linear Feet per Minute - LFM): | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | **100 (0.5 m/s)** | 3.84 | | **300 (1.5 m/s)** | 1.59 | | **500 (2.5 m/s)** | 1.18 | --- ## 4. Typical Applications This specific size (54mm) is commonly used for: * **ASICs and FPGAs:** High-speed processing units in networking gear. * **Embedded Systems:** Industrial PCs where active fan cooling may be limited. * **Power Modules:** Large voltage regulators or motor drivers that generate significant heat.
