The **ATS-04H-81-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 power transistors to prevent thermal throttling or hardware failure. --- ### 1. Technical Specifications The following table outlines the physical and thermal properties of this specific model: | Property | Specification | | :--- | :--- | | **Series** | pushPIN™ | | **Material** | Aluminum (AL6063) | | **Attachment Method** | Push-Pin (Plastic/Brass) | | **Dimensions** | 30.00mm x 30.00mm | | **Height (Fin)** | 20.00mm | | **Fin Style** | Square Pattern (Straight/Cross-Cut) | | **Thermal Resistance** | 14.22 °C/W @ Unducted Flow | | **Finish** | Blue Anodized | | **Thermal Interface Material** | T412 (Phase Change) | --- ### 2. Key Components & Design Features #### A. The Fin Design The "81" in the part number indicates a specific fin density and geometry. This model utilizes a **square pattern** of fins which allows for multi-directional airflow. This is critical in compact electronic enclosures where air may not move in a perfectly straight path. #### B. Push-Pin Attachment Mechanism Instead of using messy adhesives or permanent solder, this part uses a **Push-Pin** system: - **Spring-loaded:** Ensures constant, even pressure across the electronic component (die). - **Tool-less:** Often allows for quick installation. - **Reliability:** Prevents the heat sink from shifting during vibration or shipping. #### C. Thermal Interface Material (TIM) The part comes pre-applied with **T412**, a high-performance phase-change material. - **Function:** It fills microscopic air gaps between the heat sink and the chip. - **Benefit:** Reduces thermal contact resistance, ensuring the heat moves efficiently from the silicon into the aluminum fins. --- ### 3.
