The **ATS-20D-178-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic components like CPUs, GPUs, or power transistors to ensure their reliability and performance. --- ## 1. Technical Specifications The following table outlines the physical and thermal characteristics of this specific part number: | Feature | Specification | | :--- | :--- | | **Part Number** | ATS-20D-178-C2-R0 | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Dimensions** | 35mm x 35mm x 15mm | | **Fin Style** | Straight | | **Thermal Resistance** | 4.82 °C/W (@ 1.0 m/s) | | **Compliance** | RoHS Compliant | --- ## 2. Component Analysis This part consists of three primary electronic-mechanical sub-systems: ### A. The Heat Sink Body (Base & Fins) * **Thermal Interface:** The flat base is designed to sit atop a heat-generating component. It is usually paired with a Thermal Interface Material (TIM), such as thermal paste or a phase-change pad, to fill microscopic air gaps. * **Fin Design:** The straight-fin design allows for efficient airflow, particularly in systems with a dedicated cooling fan (active cooling) or specific chassis airflow (passive cooling). ### B. pushPIN™ Attachment System Unlike adhesive tapes that can fail under high heat, this part uses the **pushPIN™** system. It consists of: * **Compression Springs:** These provide precise, uniform pressure across the component surface, maximizing heat transfer. * **Brass/Plastic Pins:** These lock into pre-drilled holes in the Printed Circuit Board (PCB). ### C. Material and Coating * **Aluminum 6063:** Chosen for its high thermal conductivity and lightweight properties. * **Blue Anodization:** This is not just for aesthetics; the anodized layer provides increased corrosion resistance and slightly improves surface emissivity for better radiant cooling. --- ## 3. Application Use Cases This specific heat sink is typically used in environments where PCB real estate is limited but thermal loads are moderate: 1. **Network Switches/Routers:** Cooling ASICs and processors. 2. **Industrial Power Supplies:** Managing heat from MOSFETs or voltage regulators. 3. **Embedded Systems:** Protecting small-form-factor computer modules.
