The **ATS-04H-151-C1-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 integrated circuits. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Fin Style** | Straight Fin | | **Finish** | Blue Anodized | | **Attachment Method** | Push Pin (with Springs) | | **Thermal Resistance** | 3.90°C/W (at 200 LFM) | | **Dimensions (L x W x H)** | 35mm x 35mm x 10mm | | **Pressure Type** | Low Pressure | --- ### 2. Component Analysis #### A. Thermal Interface Material (TIM) The "C1" in the part number indicates that the heat sink comes pre-applied with **ATS-51**, a high-performance thermal grease. This eliminates the need for manual application of thermal paste during assembly, ensuring optimal heat transfer from the chip to the aluminum. #### B. Mounting Mechanism (Push Pins) This part uses a **spring-loaded push pin** system. This is critical for electronics because: * **Constant Pressure:** It ensures the heat sink is pressed firmly against the component surface. * **Ease of Assembly:** It allows for quick installation into pre-drilled holes in the PCB. * **Vibration Resistance:** The springs absorb mechanical shocks, preventing the heat sink from detaching. #### C. Airflow Efficiency The **straight fin design** is optimized for high-velocity airflow environments. Unlike cross-cut or pin-fin designs, straight fins offer lower resistance to moving air, making them ideal for servers or desktop cases where fans provide a steady directional breeze. --- ### 3. Applications * **Embedded Systems:** Cooling industrial microprocessors. * **Networking:** Keeping routers and switches from throttling due to heat. * **Telecom:** Used in high-speed data transmission modules.
