The **ATS-17B-25-C2-R0** is a specific part number for a high-performance **Heat Sink** manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "push pin" attachment series designed for cooling electronic components like CPUs, GPUs, and power modules. --- ### 1. Technical Specifications Below are the primary physical and thermal characteristics of the component: | Feature | Specification | |:---|:---| | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions** | 60mm x 60mm x 25mm | | **Fin Type** | XCUT (Cross-Cut) | | **Attachment Method** | Push Pin (Plastic) | | **Thermal Resistance** | ~6.25°C/W (Natural Convection) | | **Spring Type** | Compression Spring | --- ### 2. Breakdown of the Part Number The nomenclature identifies specific attributes of the cooling solution: * **ATS-17**: Refers to the specific series of heat sinks with pre-drilled holes for push-pin mounting. * **B**: Refers to the material or revision code (typically Aluminum). * **25**: Indicates the height of the heat sink (25mm). * **C2**: Refers to the specific thermal interface material (TIM) or specific kit configuration (usually indicates a T766 Chomerics thermal pad). * **R0**: Refers to the RoHS compliance status and revision level. --- ### 3. Key Electronic Functions While the heat sink itself is passive (no moving parts), its role in an electronic circuit is critical: 1. **Thermal Management**: It increases the surface area of a heat-generating component (like a microprocessor), allowing heat to dissipate into the ambient air via convection. 2. **Reliability**: By keeping the junction temperature ($T_j$) of a semiconductor within safe limits, it prevents thermal throttling and extends the lifespan of the silicon. 3. **Mechanical Mounting**: The use of **push pins** and springs provides a consistent "clamping force," ensuring that the thermal interface material (TIM) is compressed evenly for maximum heat transfer. --- ### 4. Comparison: XCUT vs. Straight Fin The ATS-17B-25-C2-R0 utilizes a **Cross-Cut (XCUT)** fin design: * **Straight Fin**: Best for high-velocity, unidirectional airflow. * **XCUT (This Model)**: Allows for "omni-directional" airflow. This is ideal when the direction of the fan's exhaust isn't perfectly aligned with the heat sink, or in systems with turbulent air.
