The **ATS-18B-38-C2-R0** is a high-performance electronic thermal management component, specifically a **heat sink** designed by Advanced Thermal Solutions (ATS). It belongs to the "maxiFLOW™" product line, which is engineered to provide maximum cooling in constrained airflow environments. --- ### 1. Technical Specifications Below are the primary physical and performance characteristics of this specific part: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Part Number** | ATS-18B-38-C2-R0 | | **Dimensions (L x W x H)** | 36.83mm x 41.28mm x 22.86mm | | **Material** | Aluminum (Anodized Blue) | | **Fin Style** | Tapered Fin (maxiFLOW™) | | **Attachment Method** | pushPIN™ | | **Thermal Resistance** | 2.10°C/W (at 200 LFM) | | **Thermal Interface Material** | T766 (Pre-applied) | --- ### 2. Design and Functional Components #### A. The Heat Sink Body (maxiFLOW™) Unlike standard straight-fin heat sinks, the maxiFLOW™ design uses a **tapered fin** structure. This geometry is optimized to increase surface area while reducing pressure drop, allowing air to flow more easily through the fins even in high-density PCB layouts. #### B. The pushPIN™ Attachment System The suffix of the part number refers to the attachment mechanism. This model uses a **pushPIN™** system, which typically includes: * **Brass or Plastic Pins:** To secure the sink to the PCB. * **Compression Springs:** These ensure a consistent, specific "clamping force" (pressure) on the electronic component (CPU, FPGA, or GPU), which is critical for efficient heat transfer. #### C. Thermal Interface Material (TIM) The part comes with **T766** pre-applied to the base. This is a "Phase Change" or high-performance thermal pad that fills the microscopic air gaps between the chip and the heat sink base, significantly reducing thermal resistance. --- ### 3.
