The **ATS-18F-75-C1-R0** is a high-performance electronic thermal management component, specifically a **Heatsink** manufactured by *Advanced Thermal Solutions (ATS)*. It belongs to the "maxiFLOW™" product line, designed to optimize airflow and heat dissipation in constrained spaces. --- ### 1. Technical Specifications The part number encodes specific physical and thermal characteristics: | Feature | Specification | | :--- | :--- | | **Product Type** | Heatsink (Push-Pin Mount) | | **Material** | Aluminum (Blue Anodized) | | **Dimensions (L x W)** | 45.00mm x 45.00mm | | **Height** | 25.00mm | | **Fin Style** | maxiFLOW (Tapered Fin) | | **Thermal Resistance** | ~1.67°C/W (at 200 LFM) | | **Attachment Method** | Push-Pin (Brass or Plastic) | | **Interface Material** | T766 (Thermal Tape/Phase Change) | --- ### 2. Key Components & Design Features #### A. The maxiFLOW™ Fin Geometry Unlike standard straight-fin heatsinks, this part uses a **flared fin** design. This geometry increases the surface area while reducing pressure drop, making it highly efficient for forced-convection cooling (systems with fans). #### B. Attachment System (Push-Pins) The "R0" designation typically refers to the specific attachment kit. * **Spring-loaded Push-Pins:** These provide a consistent, calculated pressure on the electronic component (CPU, FPGA, or ASIC). * **Reliability:** This method is more robust than simple adhesive tapes, especially in high-vibration environments. #### C. Thermal Interface Material (TIM) The base comes pre-applied with a thermal interface material (typically **T766**). This fills the microscopic air gaps between the heatsink base and the chip surface to ensure maximum heat transfer. --- ### 3. Typical Applications This specific heatsink is designed for "hot" electronic components that require high-reliability cooling: * **Computing:** Northbridge/Southbridge chipsets. * **Networking:** High-speed routers, switches, and FPGA modules. * **Industrial:** Power supplies and motor controllers where airflow is directional. --- ### 4. Thermal Performance Overview The efficiency of the ATS-18F-75-C1-R0 is highly dependent on the velocity of air (measured in Linear Feet per Minute - LFM): | Air Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 200 LFM | 1.67 | | 400 LFM | 0.99 | | 600 LFM | 0.75 |
