The **ATS-H1-159-C1-R0** is a high-performance 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 that defines its physical and thermal characteristics: | Property | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions, Inc. (ATS) | | **Series** | pushPIN™ Heat Sink | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded pins) | | **Thermal Resistance** | ~10.70 °C/W (at 100 LFM) | | **Dimensions (L x W x H)** | 40mm x 40mm x 20mm | --- ### 2. Key Components & Features #### A. Fin Design * **High-Efficiency Fins:** The "H1" designation typically refers to a specific fin pattern designed for maximum surface area while maintaining low pressure drop for airflow. * **Orientation:** Designed for vertical or horizontal airflow, depending on the chassis layout. #### B. Mounting System (pushPIN™) This heat sink uses a specialized mounting mechanism rather than just adhesive: * **Push Pins:** Durable plastic pins that snap into pre-drilled holes on the PCB. * **Compression Springs:** Provides consistent pressure (clamping force) across the interface to ensure optimal thermal transfer. #### C. Thermal Interface Material (TIM) * **Pre-applied:** This specific model usually comes with a pre-applied thermal interface (often a high-performance Phase Change Material or grease) to reduce contact resistance between the component and the heat sink. --- ### 3. Application Use Cases This part is commonly found in industrial and computing environments where space is limited but heat density is high: 1. **Network Switches:** Cooling ASICs and processors. 2. **Power Electronics:** Dissipating heat from MOSFETs or IGBTs. 3. **Embedded Systems:** For industrial PCs (IPCs) where active fan cooling may not be feasible. --- ### 4. Thermal Performance Data Performance varies based on the Air Velocity (Measured in Linear Feet per Minute - LFM): | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 10.70 | | 200 (1.0 m/s) | 4.39 | | 500 (2.5 m/s) | 2.21 |
