The **ATS-19F-99-C2-R0** is a high-performance thermal management component, specifically an **Advanced Thermal Solutions (ATS) push-pin heat sink**. It is designed to cool electronic components like CPUs, GPUs, or FPGAs that generate significant heat during operation. --- ## 1. Technical Specifications Below are the primary mechanical and thermal characteristics of this part: | Parameter | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) | | **Spring Type** | Compression Spring | | **Dimensions (L x W x H)** | 45mm x 45mm x 20mm | | **Thermal Resistance** | 11.52°C/W (Unducted Flow @ 200 LFM) | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ## 2. Key Components & Design Features ### A. The Heat Sink Body (Aluminum) * **Fin Style:** It utilizes a **cross-cut** design. This allows for multi-directional airflow, making it highly effective in systems where the direction of the cooling fan's exhaust might vary. * **Material:** Extruded aluminum is used for its excellent thermal conductivity-to-weight ratio. * **Anodization:** The blue anodized coating is not just for aesthetics; it provides corrosion resistance and slightly improves emissivity for radiant heat transfer. ### B. The Attachment Mechanism (Push-Pin & Spring) * **Push-Pins:** This part uses plastic push-pins designed for standardized holes in a Printed Circuit Board (PCB). * **Compression Springs:** These ensure consistent "bond line thickness" (BLT). By applying a precise amount of downward pressure, the spring ensures the heat sink stays in firm contact with the electronic chip, even under vibration or thermal expansion. ### C. Thermal Interface Material (TIM) * The **T766** phase-change material is pre-applied to the base. * **Function:** It fills the microscopic air gaps between the heat source (the chip) and the heat sink base, significantly reducing thermal contact resistance. --- ## 3. Operational Logic When an electronic component (like a processor) operates, it generates heat. The ATS-19F-99-C2-R0 works by: 1. **Conduction:** Heat moves from the chip through the T766 TIM into the aluminum base. 2. **Spreading:** The heat spreads vertically and horizontally through the aluminum fins. 3. **Convection:** Air moving through the cross-cut fins (either via natural convection or a system fan) carries the heat away into the ambient environment. ---
