## Technical Overview: ATS-18B-83-C1-R0 The **ATS-18B-83-C1-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It belongs to the **maxiFLOW™** product line, specifically designed for cooling electronic components such as processors, FPGAs, and ASICs that require efficient heat dissipation in constrained airflow environments. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (Blue Anodized) | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 1.57°C/W (at 200 LFM) | | **Dimensions** | 30mm x 30mm x 30mm | | **Base Height** | 2.50 mm | | **Fin Pitch** | Coarse / High-performance fins | --- ### 2. Component Design & Materials The "electronic parts" or physical construction of this assembly consists of several critical elements: * **Heat Sink Body:** Constructed from high-grade aluminum. The **maxiFLOW™** design features a tapered fin structure that increases the surface area while minimizing pressure drop. * **pushPIN™ Attachment:** This is the mounting mechanism. It uses a plastic or brass pin combined with a compression spring to ensure even pressure across the electronic component (die), optimizing thermal contact. * **Thermal Interface Material (TIM):** This specific model typically comes pre-applied with **ATS-CPX-700**, a high-performance thermal pad or grease, ensuring there are no air gaps between the component and the heat sink. * **Blue Anodized Finish:** The surface treatment is not just aesthetic; it provides corrosion resistance and increases thermal emissivity. --- ### 3. Thermal Performance Analysis The performance of the ATS-18B-83-C1-R0 is measured by its ability to dissipate heat based on airflow (LFM - Linear Feet per Minute): * **Unducted Flow:** At low airflow (200 LFM), the thermal resistance is **1.57°C/W**. * **High Airflow:** At 700 LFM, the resistance drops significantly to approximately **0.67°C/W**. * **Pressure Drop:** The design is optimized to allow air to pass through the fins easily, preventing the "bottleneck" effect common in dense fin designs. --- ### 4. Ordering Information Breakdown The part number **ATS-18B-83-C1-R0** can be decoded as follows: 1. **ATS:** Manufacturer (Advanced Thermal Solutions). 2. **18B:** Series/Revision code. 3. **83:** Specific size/footprint code. 4. **C1:** Material and Finish (Blue Anodized Aluminum). 5. **R0:** Revision or Packaging variant.
