The **ATS-20D-20-C2-R0** is a high-performance thermal management component, specifically an aluminum heat sink designed for cooling electronic components such as CPUs, GPUs, or power transistors. --- ### 1. Technical Specifications The part number follows a specific nomenclature from the manufacturer, **Advanced Thermal Solutions (ATS)**. | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Lightweight & High Thermal Conductivity) | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded pins) | | **Dimensions (L x W x H)** | 45mm x 45mm x 25mm | | **Thermal Resistance** | ~7.14 °C/W (at 1.0 m/s airflow) | | **Flow Direction** | Vertical (Cross-cut for multi-directional airflow) | --- ### 2. Design Characteristics This heat sink is part of the **pushPIN™** series, which is engineered for secure and reliable attachment to a Printed Circuit Board (PCB). * **Cross-Cut Fin Pattern:** Unlike straight-fin heat sinks, the cross-cut design allows for efficient cooling even if the airflow is not perfectly aligned. It is ideal for crowded PCB environments. * **Push-Pin Mounting:** It uses two plastic or brass pins with internal springs. This ensures constant pressure (clamping force) on the electronic component, which improves the heat transfer through the Thermal Interface Material (TIM). * **Blue Anodized Coating:** The blue coating is not just for aesthetics; it provides corrosion resistance and increases surface emissivity, which slightly improves radiative cooling. --- ### 3. Application Use Cases This specific part is typically found in: 1. **Telecommunications Equipment:** For cooling high-speed processors or ASICs. 2. **Embedded Systems:** Industrial PCs where space is limited but thermal loads are high. 3. **Power Supplies:** Cooling MOSFETs or Voltage Regulators (VRMs). --- ### 4. Thermal Performance Data Performance varies based on the air velocity (LFM - Linear Feet per Minute): | Air Velocity | 1.0 m/s (200 LFM) | 2.0 m/s (400 LFM) | 3.0 m/s (600 LFM) | | :--- | :--- | :--- | :--- | | **Thermal Resistance** | 7.14 °C/W | 4.62 °C/W | 3.67 °C/W |
