The **ATS-12B-178-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 | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ HS | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 35.00mm x 35.00mm x 25.00mm | | **Attachment Method** | pushPIN™ (Spring-loaded pins) | | **Thermal Resistance** | ~4.82°C/W (Unducted Flow @ 1.0 m/s) | | **Fin Type** | Straight Fin (Cross-cut) | --- ## 2. Key Components & Design The "Electronic" functionality of this part is passive, meaning it does not require power, but its design is critical for electronic circuit stability. ### A. The pushPIN™ Attachment System Instead of using messy thermal adhesives or standard screws, this model uses a proprietary **pushPIN™** system. * **Springs:** Provides a precise "Required Compression" force (the "R0" in the part number). * **Pins:** Nylon or brass pins that lock into the PCB holes for a secure, vibration-resistant fit. ### B. Material and Coating * **Aluminum Body:** Chosen for its high thermal conductivity and lightweight properties. * **Blue Anodized Finish:** This is not just for aesthetics; the anodization layer increases surface emissivity, which improves heat radiation and protects the aluminum from corrosion. ### C. Thermal Interface Material (TIM) The **"C2"** designation in the part number typically refers to the pre-applied thermal interface material. * **Type:** Usually a high-performance thermal grease or pad. * **Function:** Fills the microscopic air gaps between the heat source (chip) and the heat sink base to ensure maximum heat transfer. --- ## 3. Performance Analysis The efficiency of the ATS-12B-178-C2-R0 is measured by its ability to move heat away from a junction. | Airflow Velocity (m/s) | Thermal Resistance (°C/W) | | :--- | :--- | | 1.0 (200 LFM) | 4.82 | | 2.0 (400 LFM) | 2.57 | | 3.0 (600 LFM) | 2.11 | --- ## 4.
