The **ATS-15E-159-C1-R0** is a high-performance heat sink manufactured by Advanced Thermal Solutions (ATS) as part of their **push-pin** attachment series. It is designed for cooling electronic components such as CPUs, GPUs, and other integrated circuits. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) | | **Fin Type** | XCUT (Cross-cut) | | **Thermal Resistance** | 10.66°C/W (at 100 LFM) | | **Dimensions (L x W x H)** | 45mm x 45mm x 10mm | --- ### 2. Mechanical Design and Components The part is engineered for specific airflow conditions and mechanical stability: #### A. The Heat Sink Body * **Material:** Extruded aluminum, which provides a balance between lightweight design and efficient thermal conductivity. * **XCUT Fin Pattern:** The "XCUT" geometry creates a cross-cut pattern. This allows airflow to enter from multiple directions, making it ideal for systems where the airflow path is not strictly linear. * **Blue Anodization:** This is not just aesthetic; it protects the aluminum from corrosion and slightly improves radiant heat emissivity. #### B. The Attachment System (Push-Pins) * **Spring-Loaded Pins:** The "R0" suffix typically denotes the specific pin and spring assembly. These pins provide a precise "Pre-load" force, ensuring the heat sink makes consistent contact with the electronic chip. * **Brass/Plastic Pins:** Most versions use a durable plastic push-pin with a stainless steel spring to maintain downward pressure without damaging the PCB. #### C. Thermal Interface Material (TIM) * The part usually comes with **pre-applied thermal tape** or a phase-change material on the base. This eliminates the need for external thermal paste and ensures there are no air gaps between the component and the heat sink. --- ### 3. Thermal Performance Profile The efficiency of this part depends heavily on the airflow (LFM - Linear Feet per Minute) within the enclosure: | Airflow (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | **100 (Natural/Low)** | 10.66 | | **300 (Medium)** | 4.47 | | **500 (High)** | 3.39 | --- ### 4. Integration Usage * **Compatibility:** Designed for a 45mm footprint. It requires specific mounting holes drilled into the PCB at a pitch designated by the ATS push-pin standard. * **Application:** Commonly used in telecommunications, networking equipment (routers/switches), and industrial embedded systems.
