The **ATS-19B-71-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by *Advanced Thermal Solutions (ATS)*. It belongs to the **maxiFLOW™** series, designed to dissipate heat from high-power electronic components like CPUs, GPUs, and ASICs. ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Part Number** | ATS-19B-71-C2-R0 | | **Material** | Aluminum (with Blue Anodized Finish) | | **Attachment Method** | pushPIN™ | | **Dimensions (L x W x H)** | 45mm x 45mm x 30mm | | **Thermal Resistance** | 6.69°C/W (at 100 LFM) | | **Airflow Path** | Straight Fin (maxiFLOW™ design) | | **Compliance** | RoHS-6 and REACH compliant | --- ### 2. Key Electronic & Mechanical Components The "electronic parts" of this assembly aren't active silicon but rather the mechanical interface components that ensure thermal efficiency: #### A. The Heat Sink Body (maxiFLOW™) The core component is the aluminum fin structure. The **maxiFLOW™** geometry is designed to maximize surface area while reducing pressure drop. This allows air to flow through the fins more efficiently, which is critical for densely packed electronic enclosures. #### B. The pushPIN™ Attachment System Instead of simple adhesive tape, this part uses a **pushPIN™** system. * **Springs:** Provides a consistent "Normal Force" (pressure) on the electronic chip to ensure high thermal conductivity. * **Plastic/Brass Pins:** Secure the heat sink to the PCB through pre-drilled holes. #### C. Thermal Interface Material (TIM) The "C2" in the part number refers to the **T766 Thermal Phase Change Compound**. * This material is pre-applied to the base. * When the electronic component heats up, the TIM softens and fills microscopic air gaps between the chip and the heat sink, significantly lowering thermal resistance. --- ### 3. Part Number Breakdown Understanding the nomenclature helps identify the specific electronic requirements: * **ATS**: Advanced Thermal Solutions (Manufacturer). * **19B**: Series designation (Standard MaxiFlow). * **71**: Specific size/geometry code. * **C2**: Indicates the specific Thermal Interface Material (T766) and Blue Anodized finish. * **R0**: Revision/Packaging code. --- ### 4. Application in Electronics This part is typically used in: 1. **Telecommunications:** Cooling high-speed network switches. 2. **Embedded Systems:** Industrial PCs where fan failure is not an option. 3. **Power Supplies:** Dissipating heat from MOSFETs or Power Modules.
