The **ATS-08B-159-C1-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** designed by Advanced Thermal Solutions (ATS). It is used to dissipate heat from electronic components such as CPUs, GPUs, or power transistors to prevent thermal throttling or hardware failure. --- ### 1. Technical Specifications The model number encodes specific physical and thermal characteristics. Here is the breakdown of the technical data: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum (High thermal conductivity) | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 45mm x 45mm x 10mm | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 20.90°C/W (at 100 LFM) | | **Fin Type** | XC-CUT (Cross-cut) | | **Base Type** | Flat | --- ### 2. Key Design Components The effectiveness of this part relies on several engineering choices: #### A. The XC-CUT Fin Pattern Unlike standard straight fins, the "XC-CUT" pattern involves straight fins with cross-cuts. This design increases surface area and creates turbulence in the airflow, which significantly improves heat transfer efficiency in low-to-medium airflow environments. #### B. pushPIN™ Attachment System This part uses a specialized mechanical attachment rather than adhesive: * **Compression Springs:** Provide precise pressure to the component, ensuring high thermal interface contact. * **Brass/Plastic Pins:** Secure the heat sink through pre-drilled holes in the PCB. #### C. Thermal Interface Material (TIM) The "R0" suffix indicates that the part typically comes with a **pre-applied phase-change material** or a high-performance thermal pad. This ensures there are no air gaps between the heat sink and the electronic chip. --- ### 3. Thermal Performance Metrics The efficiency of the ATS-08B-159-C1-R0 is measured by its thermal resistance (lower is better). Its performance varies based on the Airflow (LFM - Linear Feet per Minute): | Airflow Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | **100 (0.5 m/s)** | 20.90 | | **200 (1.0 m/s)** | 11.00 | | **400 (2.0 m/s)** | 7.10 | | **600 (3.0 m/s)** | 5.30 | --- ### 4. Applications This specific size and mounting style are common in: * **Networking Equipment:** Routers and Switches. * **Embedded Systems:** Industrial PCs and IoT Gateways. * **Power Electronics:** Voltage regulators and power supplies that generate localized heat.
