The **ATS-P1-177-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of the "pushPIN™" family, designed for cooling high-power electronic components like CPUs, GPUs, and power transistors. --- ## 1. Technical Specifications The following table highlights the core physical and thermal properties of the device: | Parameter | Specification | | :--- | :--- | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Base Dimensions** | 35.00 mm x 35.00 mm | | **Height** | 20.00 mm | | **Attachment Type** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 6.18 °C/W (at 100 LFM) | | **Fin Pattern** | Straight Fin | --- ## 2. Component Analysis ### A. Material and Design * **Aluminum 6063:** This alloy is used because of its excellent thermal conductivity and structural integrity. * **Straight Fin Design:** The fins run in parallel lines. This design is optimized for **forced-air cooling** (fan-driven) where the airflow direction is consistent across the fins. * **Blue Anodizing:** This chemical finish provides two benefits: 1. **Corrosion Resistance:** Protects the aluminum from oxidation. 2. **Increased Emissivity:** Slightly improves the radiation cooling efficiency. ### B. Mounting Mechanism (pushPIN™) The part features a specialized mounting system that includes: * **Pins and Springs:** These ensure a precise and consistent pressure (clamping force) on the electronic chip, which is critical for maximizing the effectiveness of the Thermal Interface Material (TIM). * **Plastic Push Pins:** These snap into pre-drilled holes in the PCB, making installation quick and tool-free. --- ## 3. Thermal Performance The efficiency of the heat sink is determined by the airflow (Linear Feet per Minute - LFM). As airflow increases, thermal resistance decreases: | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 6.18 | | 200 (1.0 m/s) | 3.32 | | 300 (1.5 m/s) | 2.61 | | 500 (2.5 m/s) | 2.05 | --- ## 4. Usage Example When using this part in a circuit design, the thermal interface material is usually pre-applied or added during assembly. ```python # Conceptual Calculation: Calculating Temperature Rise # Formula: Rise = Power_Dissipated (W) * Thermal_Resistance (C/W) power_of_chip = 10 # Watts thermal_resistance = 2.61 # at 300 LFM airflow temp_rise = power_of_chip * thermal_resistance print(f"Temperature Rise: {temp_rise} Degrees Celsius") ```
