The **ATS-18D-134-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "push-pin" series designed for efficient cooling of electronic components like CPUs, GPUs, and other high-heat surface-mount devices. --- ### 1. Technical Specifications The part number provides specific details about the dimensions, material, and attachment method. | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Dimensions (L x W)** | 70mm x 70mm | | **Height (Fin Height)** | 15mm | | **Attachment Type** | Push-Pin (Brass) | | **Spring Type** | Compression Spring | | **Thermal Resistance** | 4.44°C/W (at 200 LFM) | | **Fin Style** | Straight Fin | --- ### 2. Key Components & Design This electronic cooling part consists of three primary elements: 1. **The Heat Sink Body:** Large 70x70mm aluminum base with straight fins. The large surface area is designed for maximum heat dissipation via convection. 2. **Push-Pin Mechanism:** This part uses a brass push-pin system. This allows for secure attachment to the PCB (Printed Circuit Board) through pre-drilled holes, ensuring consistent pressure on the heat source. 3. **Thermal Interface Material (TIM):** This specific model typically comes with **T766** pre-applied. This is a phase-change material that fills microscopic air gaps between the component and the heat sink to improve heat transfer. --- ### 3. Thermal Performance Profile The effectiveness of this heat sink depends on the airflow (measured in Linear Feet per Minute - LFM) within the electronic enclosure. | Airflow (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | **200 (1.0 m/s)** | 4.44 | | **400 (2.0 m/s)** | 3.10 | | **600 (3.0 m/s)** | 2.58 | --- ### 4. Common Applications * **Networking Gear:** Switches and routers where high-speed chips generate significant heat. * **Embedded Systems:** Industrial PCs and controllers. * **Power Supplies:** Cooling voltage regulators or power transistors. ---
