The **ATS-P2-194-C3-R0** is a specific high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "push-pin" series designed for cooling electronic components such as CPUs, GPUs, and high-power ICs. ### 1. Technical Specifications Below are the primary physical and thermal characteristics of the component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Blue Anodized) | | **Dimensions** | 45mm x 45mm | | **Height** | 25mm | | **Fin Style** | Straight Fin | | **Attachment Method** | Push-Pin (Plastic) | | **Spring Type** | Compression Spring | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Key Electronic & Mechanical Components #### A. The Heat Sink Body (Aluminum) The core "part" is an extruded aluminum block. The **Blue Anodized** finish is not just for aesthetics; it provides: * **Corrosion Resistance:** Protects the aluminum from environmental oxidation. * **Electrical Insulation:** The anodized layer is non-conductive, reducing the risk of short-circuits if the sink contacts nearby components. * **Improved Emissivity:** Enhances heat radiation compared to polished aluminum. #### B. The Push-Pin Attachment System Unlike adhesive-based heat sinks, the `-P2` designation indicates a mechanical attachment: * **Plastic Push-Pins:** These provide a secure, reliable attachment to the PCB. * **Compression Springs:** The "R0" variant typically includes a specific spring tension that ensures uniform pressure across the component surface, maximizing heat transfer. #### C. Thermal Interface Material (TIM) The unit comes with **T766** pre-applied to the base. * **Function:** It fills microscopic air gaps between the heat sink and the electronic chip. * **Benefit:** Reduces thermal resistance significantly compared to "dry" mounting. --- ### 3. Thermal Performance Profile The efficiency of this part depends on the airflow (LFM - Linear Feet per Minute) within the electronic enclosure: | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | **200 (1.0 m/s)** | 2.50 | | **400 (2.0 m/s)** | 1.60 | | **600 (3.0 m/s)** | 1.30 | | **800 (4.0 m/s)** | 1.15 | --- ### 4. Typical Applications This specific part is used in electronic systems where high heat density is an issue: * **Network Switches/Routers:** Cooling high-speed processing ASICs. * **Embedded Systems:** For industrial PCs where vibration resistance is needed (push-pins are more secure than tape). * **Power Supplies:** Cooling MOSFETs or power regulators.
