The **ATS-08F-91-C3-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic components like CPUs, GPUs, or high-power transistors. --- ### 1. Technical Specifications The model number provides specific details about its physical and thermal properties: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Series** | pushPIN™ | | **Attachment Type** | Push-Pin (Spring-loaded) | | **Material** | Aluminum (Blue Anodized) | | **Fin Style** | Straight | | **Dimensions** | 40mm x 40mm x 10mm | | **Thermal Resistance** | 22.00°C/W (Unducted Flow @ 100 LFM) | --- ### 2. Breakdown of the Component Parts The assembly consists of four primary electronic/mechanical sub-parts: #### A. The Heat Sink Body * **Material:** High-grade aluminum which offers high thermal conductivity. * **Design:** Features a "Straight-Fin" pattern to maximize surface area for air contact. * **Base:** A flat, polished base ensures maximum contact with the electronic chip's surface. #### B. The pushPIN™ Fasteners * Instead of using thermal adhesive (which can fail over time), this part uses specialized plastic or metal pins. * These pins go through pre-drilled holes in the PCB (Printed Circuit Board) to provide a secure mechanical connection. #### C. Compression Springs * Each push-pin is equipped with a calibrated spring. * This ensures **constant pressure** is applied to the chip, preventing the heat sink from shifting and maintaining optimal heat transfer. #### D. Thermal Interface Material (TIM) * The "C3" in the part number indicates it comes with a **pre-applied thermal interface** (usually a phase-change material or high-quality grease). * This fills microscopic gaps between the chip and the heat sink. --- ### 3. Application Use Cases This specific part is used in environments where vertical space is limited but high cooling efficiency is required: * **Low-profile Servers:** The 10mm height is ideal for 1U rack-mount hardware. * **Networking Equipment:** Routers and switches with high-speed processors. * **Embedded Systems:** Industrial PCs where vibration resistance (provided by the push-pins) is necessary. --- ### 4. Thermal Performance Comparison *Values represent thermal resistance (°C/W); lower is better.* | Air Velocity (LFM) | 100 | 200 | 300 | 400 | | :--- | :--- | :--- | :--- | :--- | | **Unducted Flow** | 22.00 | 10.20 | 5.90 | 4.10 | | **Ducted Flow** | 3.90 | 2.50 | 2.10 | 1.80 |
