The **ATS-18F-04-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "push pin" series designed for cooling electronic components such as CPUs, GPUs, and other high-heat surface-mount devices. --- ### ## Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push Pin (Plastic) | | **Thermal Resistance** | 11.55°C/W (at 200 LFM) | | **Dimensions (L x W x H)** | 36.83mm x 36.83mm x 22.86mm | | **Fin Style** | Straight Fin | --- ### ## Component Analysis ### 1. The Heat Sink Body The part is made of **Aluminum 6063**, chosen for its excellent thermal conductivity and lightweight properties. The **Blue Anodized** finish is not just for aesthetics; it provides surface protection against corrosion and increases the "emissivity" of the surface, which slightly improves heat dissipation through radiation. ### 2. Attachment Mechanism (Push Pins) The "04" and "C2" codes in the part number refer to the attachment hardware. * **Push Pins:** Uses flexible plastic pins that snap into pre-drilled holes on the Printed Circuit Board (PCB). * **Springs:** The pins are paired with compression springs to ensure constant, even pressure between the heat sink and the component, maximizing thermal transfer. ### 3. Thermal Interface Material (TIM) This specific model usually comes with **T766** pre-applied thermal phase-change material or a thermal tape. This fills the microscopic air gaps between the component and the heat sink base. ### 4. Cooling Performance The "Straight Fin" design is optimized for **forced air cooling** (environments with fans). The fins are spaced to allow air to flow through the channels, carrying heat away from the base. --- ### ## Common Applications * **Networking Gear:** Cooling for routers and switches. * **Embedded Systems:** Industrial PCs and controllers. * **Power Supplies:** Regulating heat in voltage converters.
