The **ATS-18F-72-C3-R0** is a high-performance 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 power transistors to ensure operational stability. --- ### 1. Technical Specifications Below is a breakdown of the physical and thermal properties of this specific part: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions (L x W)** | 45.00 mm x 45.00 mm | | **Height** | 35.00 mm | | **Fin Type** | Straight Fin | | **Thermal Resistance** | 0.82°C/W (at 200 LFM) | --- ### 2. Key Electronic Components & Design The "pushPIN™" system is a critical feature of this electronic part, ensuring optimal contact between the heat sink and the semiconductor. #### A. Thermal Interface Material (TIM) The "C3" in the part number indicates that this unit comes pre-applied with **T412 Phase Change Material**. This is an electronic-grade thermal interface that fills microscopic air gaps between the component die and the heat sink base to improve heat transfer. #### B. Attachment Hardware * **Springs:** Uses brass or steel springs to provide consistent pressure. * **Pins:** Features plastic or aluminum pins that lock into the PCB (Printed Circuit Board) holes. #### C. Airflow Optimization The straight-fin design is optimized for **forced air cooling** (fans). In an electronic assembly, the spacing between the fins is calculated to minimize pressure drop while maximizing the surface area exposed to the air. --- ### 3.
