## Technical Overview: ATS-19B-57-C2-R0 The **ATS-19B-57-C2-R0** is a high-performance **Heat Sink** assembly designed by Advanced Thermal Solutions (ATS). It belongs to the **maxiFLOW™** series, which is characterized by its unique flared fin geometry designed to maximize surface area and cooling efficiency in constrained airflows. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | maxiFLOW™ | | **Material** | Aluminum (Blue Anodized) | | **Thermal Resistance** | 2.45°C/W (at 200 LFM) | | **Dimensions (L x W)** | 37.00mm x 37.00mm | | **Height** | 14.50mm | | **Attachment Method** | pushPIN™ (Brass Springs) | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Design Components The "Electronic Part" consists of several integrated sub-components that work together to dissipate heat from high-power semiconductors (like CPUs, FPGAs, or GPUs): * **Heat Sink Body:** Constructed from high-grade aluminum. The flared fin design increases the surface area for convective heat transfer while minimizing pressure drop across the sink. * **pushPIN™ Attachment:** This is the mounting mechanism. It uses a specific hole pattern on the PCB. The brass springs provide a precise and consistent pressure (load) on the electronic component to ensure optimal contact. * **Thermal Interface Material (TIM):** The **T766** phase-change material is pre-applied to the base. This fills the microscopic air gaps between the chip surface and the heat sink base, significantly reducing thermal resistance. * **Blue Anodized Coating:** Not only provides aesthetic value but also offers corrosion resistance and slightly improves emissivity. --- ### 3. Thermal Performance Metrics The efficiency of this part is measured by how well it lowers the temperature per watt of power generated. | Air Velocity (LFM) | Velocity (m/s) | Thermal Resistance (°C/W) | | :--- | :--- | :--- | | 200 | 1.0 | 2.45 | | 300 | 1.5 | 1.92 | | 400 | 2.0 | 1.65 | | 500 | 2.5 | 1.48 | | 600 | 3.0 | 1.35 | --- ### 4.
