### Overview of ATS-17B-70-C2-R0 The **ATS-17B-70-C2-R0** is a high-performance **Heat Sink** assembly manufactured by Advanced Thermal Solutions (ATS). It is specifically designed for cooling electronic components such as CPUs, GPUs, FPGAs, and ASICs that generate significant heat during operation. --- ### 1. Technical Specifications The part number follows a specific nomenclature used by ATS to define its physical and thermal characteristics. | Feature | Specification | Description | | :--- | :--- | :--- | | **Material** | Aluminum | Lightweight with high thermal conductivity. | | **Finish** | Blue Anodized | Enhances corrosion resistance and emissivity. | | **Dimensions** | 45mm x 45mm x 25mm | The footprint and height of the sink. | | **Fin Style** | Push-Pin / Straight Fin | Designed for vertical airflow efficiency. | | **Thermal Interface** | T766 | High-quality Phase Change Material (PCM). | | **Attachment** | Push-Pin (Brass) | Secure mechanical mounting to the PCB. | --- ### 2. Key Components & Electronics Context #### A. The Heat Sink Body The body is constructed from **Aluminum 6063**, which is the industry standard for thermal management. It functions as a passive heat exchanger, transferring heat from the electronic chip to the surrounding air. #### B. Thermal Interface Material (TIM) The "R0" at the end of the part number indicates the specific TIM applied to the base. * **Purpose:** To fill microscopic air gaps between the component and the heat sink. * **Specifics:** Usually features **T766**, a thermal grease or pad that ensures maximum heat transfer efficiency. #### C. Attachment Mechanism (Push-Pins) Unlike adhesive-based heat sinks, this model uses **Push-Pins and Springs**. * **Reliability:** Provides consistent pressure on the chip, which is critical for maintaining thermal contact under vibration or thermal expansion. * **PCB Compatibility:** Requires pre-drilled holes in the Printed Circuit Board (PCB). --- ### 3. Performance Metrics Thermal performance is measured by "Thermal Resistance" ($^\circ C/W$). The lower the number, the better the heat sink is at dissipating heat. | Airflow Velocity | Thermal Resistance (Unducted) | | :--- | :--- | | **1.0 m/s (200 LFM)** | ~3.60 °C/W | | **2.5 m/s (500 LFM)** | ~2.10 °C/W | --- ### 4. Application Use-Cases * **Telecommunications:** Used in routers and switches. * **Industrial PC:** Cooling processors in fanless or high-airflow enclosures. * **Power Supplies:** Managing heat for high-voltage regulators.
