The **ATS-18B-160-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "blue ICE" series, specifically designed for cooling electronic components like CPUs, GPUs, and other high-heat integrated circuits. --- ### 1. Technical Specifications The part number follows a specific nomenclature used by ATS to describe its physical and thermal characteristics. | Parameter | Specification | Details | | :--- | :--- | :--- | | **Material** | Aluminum | Lightweight with high thermal conductivity | | **Finish** | Blue Anodized | Enhances corrosion resistance and thermal radiation | | **Dimensions** | 45 x 45 x 15 mm | Length x Width x Height | | **Attachment Type** | push-pin | Uses plastic pins and springs for mounting | | **Thermal Resistance** | 6.67 °C/W | Based on natural convection | | **Flow Pattern** | XC-Cut | Straight fin design for multi-directional airflow | --- ### 2. Key Components & Design Features #### A. The XC-Cut Fin Design The heat sink features a straight-fin design (often referred to as XC-Cut). This geometry is optimized for: * **Airflow Efficiency:** Minimal pressure drop across the fins. * **Versatility:** Works well in both forced-air (fan) and natural convection environments. #### B. Push-Pin Attachment Mechanism Instead of adhesive tapes, this model uses a **push-pin and spring** assembly. * **Consistent Pressure:** The springs ensure a constant, predefined force on the electronic chip, which optimizes the thermal interface. * **Secure Mounting:** Requires pre-drilled holes in the PCB (Printed Circuit Board). #### C. Thermal Interface Material (TIM) The "R0" suffix usually indicates the inclusion of a high-performance thermal interface material pre-applied to the base. * **Function:** Fills microscopic air gaps between the component and the heat sink base to maximize heat transfer. --- ### 3. Application Use Cases This specific heat sink size (45mm) is commonly used for: * **Network Switches:** Cooling ASICs and processors. * **Industrial PCs:** Thermal management for embedded systems. * **Power Supplies:** Heat dissipation for high-output voltage regulators. ---
