The **ATS-55375W-C1-R0** is a high-performance heat sink manufactured by *Advanced Thermal Solutions (ATS)*. It belongs to the **maxiFLOW™** series, which is specifically designed to provide high thermal performance in environments with constrained airflow. --- ### 1. Technical Specifications The following table summarizes the key physical and thermal characteristics of the component: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | maxiFLOW™ | | **Dimension (L x W x H)** | 37.5mm x 37.5mm x 24.5mm | | **Attachment Method** | maxiGRIP™ (Frame Clip) | | **Thermal Resistance** | 1.9 °C/W @ 200 LFM | | **Material** | Aluminum (Anodized Blue) | | **Fin Style** | Spread Fin (Tapered) | --- ### 2. Key Design Elements #### A. maxiFLOW™ Fin Geometry Unlike standard straight-fin heat sinks, the maxiFLOW™ design features a flared or "spread" fin pattern. This increases the surface area and creates more turbulence in the airflow, which significantly lowers the thermal resistance compared to traditional designs of the same footprint. #### B. maxiGRIP™ Attachment System This part uses a specialized mechanical attachment system instead of thermal tape or push-pins: * **Plastic Frame Clip:** A high-tension plastic frame clips around the electronic component (usually a BGA). * **Stainless Steel Spring Clip:** A "steady-force" spring clip applies consistent pressure across the center of the heat sink, ensuring optimal contact with the die. * **Benefits:** It eliminates the need to drill holes in the PCB and allows the heat sink to be removed or reworked easily. #### C. Thermal Interface Material (TIM) The part typically comes pre-applied with a high-performance **Phase Change Material (PCM)**. This material stays solid at room temperature for easy handling but melts at operating temperatures to fill microscopic air gaps between the component and the heat sink. --- ### 3. Common Applications This heat sink is designed for cooling high-heat-dissipating surface-mount components, such as: * **FPGAs & ASICs:** Used in telecommunications and networking gear. * **Processors:** Embedded CPUs or GPUs in industrial computing. * **Video Encoders:** Components found in high-definition broadcasting equipment. ---
