The **ATS-05D-174-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "push pin" series, designed specifically for cooling electronic components such as CPUs, GPUs, and other high-heat integrated circuits. --- ### 1. Technical Specifications The following table outlines the key physical and thermal properties of the component: | Feature | Specification | | :--- | :--- | | **Part Number** | ATS-05D-174-C2-R0 | | **Material** | Aluminum (Al) | | **Attachment Method** | Push Pin (with Springs) | | **Dimensions** | 30mm x 30mm x 35mm | | **Fin Style** | Straight Fin | | **Thermal Resistance** | 4.02°C/W (at 200 LFM) | | **Finish** | Blue Anodized | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Design Components #### A. Fin Geometry The "Straight Fin" design is optimized for **forced-air cooling** (airflow from a fan). The vertical fins provide a large surface area to dissipate heat while minimizing pressure drop as air passes through the unit. #### B. Push Pin Attachment This part uses a spring-loaded push pin system. * **Ease of Install:** Allows for quick assembly on PCBs with pre-drilled holes. * **Compression Force:** The springs ensure a consistent and reliable pressure between the heat sink and the component, which is vital for thermal transfer. #### C. Thermal Interface Material (TIM) The unit comes with **T766** pre-applied to the base. This eliminates the need for manual application of thermal paste and ensures that microscopic air gaps between the chip and the aluminum are filled for maximum efficiency. --- ### 3. Thermal Performance Comparison Thermal performance varies based on the Airflow (LFM - Linear Feet per Minute): | Airflow (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 | 5.40 | | 200 | 4.02 | | 300 | 3.44 | | 400 | 3.10 | --- ### 4. Typical Applications * **Embedded Systems:** Industrial PCs and controllers. * **Telecommunications:** High-speed routers and switches. * **Power Supplies:** Cooling voltage regulators and MOSFETs.
