The **ATS-08F-190-C2-R0** is a high-performance electronic 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: | Feature | Specification | Details | | :--- | :--- | :--- | | **Part Number** | ATS-08F-190-C2-R0 | Standard Product Line | | **Material** | Aluminum | High thermal conductivity & lightweight | | **Finish** | Blue Anodized | Enhances radiation and provides corrosion resistance | | **Dimensions** | 45mm x 45mm x 25mm | Standard square footprint | | **Attachment Method** | pushPIN™ | Spring-loaded mounting for consistent pressure | | **Thermal Resistance** | ~3.62 °C/W (at 200 LFM) | Efficiency in air cooling | | **Fin Style** | Straight Fin | Optimized for longitudinal airflow | --- ### 2. Key Components & Design Features #### A. The pushPIN™ Attachment System This is a critical electronic hardware feature. Instead of using messy thermal adhesives that are permanent, this part uses a mechanical push-pin system. * **Consistency:** Ensures even pressure across the thermal interface material (TIM). * **Reliability:** Re-workable and secure against high-vibration environments. * **Springs:** Usually brass or steel, calibrated to provide specific clamping force. #### B. Thermal Interface Material (TIM) The "C2" in the part number typically refers to the pre-applied thermal interface. * **T766 Phase Change Material:** This acts as a bridge between the electronic component (IC) and the aluminum. It fills microscopic air gaps to maximize heat transfer. #### C. Fin Geometry The "Straight Fin" design is engineered for **Forced Convection**. It works best when paired with a fan or within a chassis with a directed air tunnel. The spacing is calculated to minimize "pressure drop" while maximizing surface area. --- ### 3. Electronic Application Use Cases This specific heat sink is typically found in the following electronic systems: 1. **Telecommunications:** Networking switches and routers where chips run hot 24/7. 2. **Power Electronics:** Dissipating heat from high-speed Voltage Regulator Modules (VRMs). 3. **Embedded Systems:** Industrial PCs where mechanical mounting (push-pins) is preferred over adhesives for long-term durability. --- ### 4. Comparison Table: Airflow vs. Thermal Resistance The effectiveness of this part depends heavily on the airflow (measured in Linear Feet per Minute - LFM): | Airflow (LFM) | Velocity (m/s) | Thermal Resistance (°C/W) | | :--- | :--- | :--- | | 100 | 0.5 | 6.62 | | 300 | 1.5 | 2.78 | | 500 | 2.5 | 2.13 |
