The **ATS-20B-174-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 overheating. --- ## 1. Technical Specifications The part number follows a specific nomenclature used by ATS to define the physical and thermal properties of the heat sink. | Parameter | Specification | Details | | :--- | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions | Leading provider of thermal management solutions. | | **Material** | Aluminum | Provides a balance of high thermal conductivity and low weight. | | **Attachment Method** | pushPIN™ | Uses a spring-loaded pin for secure, consistent pressure. | | **Dimensions** | 30.0mm x 30.0mm | The base footprint size. | | **Height** | 25.0mm | The vertical profile of the fins. | | **Thermal Resistance** | 4.02 °C/W (@ 1.0 m/s) | Measures the efficiency of heat transfer. | | **Finish** | Blue Anodized | Enhances corrosion resistance and emissivity. | --- ## 2. Core Electronic Components While the heat sink itself is mechanical, it is composed of several critical elements that interact with electronic hardware: ### A. The Base Plate The bottom surface is precision-milled to be extremely flat. This ensures maximum contact area with the electronic component (IC). In the "C2" variant, this typically includes **T766 phase change material** or a high-performance thermal interface material (TIM) pre-applied to the base to fill microscopic air gaps. ### B. The Fin Array (Cross-Cut) This model features a **cross-cut** fin design. Unlike straight fins, cross-cut fins allow for "multi-directional" airflow. This is crucial in complex electronic enclosures where air may not be blowing in a single, predictable direction. ### C. The pushPIN™ Attachment System The "20B" designation refers to the attachment mechanism. It uses a brass or plastic pin with a stainless steel spring. * **Purpose:** Ensures even pressure across the die of the electronic component. * **Safety:** Prevents the heat sink from shifting during vibration or shipping, which could damage delicate solder joints. --- ## 3. Application Use Cases This specific heat sink is typically found in: 1. **Telecommunications:** High-speed routers and switches. 2. **Embedded Systems:** Industrial PCs and automation controllers. 3. **Power Electronics:** Voltage regulators and motor drivers. ---
