## Technical Overview of ATS-18B-62-C2-R0 The **ATS-18B-62-C2-R0** is a high-performance electronic thermal management component, specifically a **Pin Fin Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is designed to dissipate heat from electronic components such as CPUs, GPUs, and power modules. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Product Series** | pushPIN™ Heat Sink Assembly | | **Attachment Type** | Push-pin (spring-loaded) | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Dimensions (L x W x H)** | 45mm x 45mm x 15mm | | **Thermal Resistance** | 16.48 °C/W (Unducted @ 1.0 m/s) | | **Thermal Interface Material (TIM)** | T766 (Pre-applied) | --- ### 2. Component Composition The assembly consists of four primary sub-parts that ensure effective cooling and secure mounting: #### A. The Heat Sink Body * **Design:** Features a "Pin Fin" geometry. Unlike straight fins, pin fins allow for omnidirectional airflow, meaning the air can enter the sink from any direction, which is ideal for systems with complex internal air turbulence. * **Material:** Made of Aluminum 6063, which offers a high strength-to-weight ratio and excellent thermal conductivity. #### B. The Push-Pin Mechanism * **Attachment:** Uses a plastic or metal push-pin (typically brass or stainless steel) with a built-in spring. * **Pressure:** The spring ensures a constant, uniform pressure between the heat sink and the heat-generating component, which is critical for maximizing thermal transfer. #### C. Thermal Interface Material (TIM) * **Type:** T766. * **Function:** This is a pre-applied phase-change material or grease located on the bottom base. It fills the microscopic air gaps between the component and the heat sink, significantly reducing thermal resistance. #### D. The Finish * **Anodization:** The blue anodized finish is not just aesthetic; it provides surface protection against corrosion and slightly increases emissivity for better radiant heat transfer. --- ### 3. Thermal Performance Profile Thermal resistance measures how effectively the part moves heat away from the chip. Lower values indicate better performance. | Airflow Velocity (m/s) | Thermal Resistance (°C/W) | | :--- | :--- | | 1.0 (200 LFM) | 16.48 | | 2.0 (400 LFM) | 6.49 | | 3.0 (600 LFM) | 4.45 | --- ### 4. Applications * **Embedded Systems:** Cooling for small form-factor industrial PCs. * **Telecommunications:** High-speed routers and switches. * **Power Supplies:** Heat dissipation for MOSFETs and Voltage Regulators.
