The **ATS-04H-71-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is designed to provide thermal management for electronic components, such as CPUs, GPUs, or high-power transistors. --- ### 1. Technical Specifications The following table summarizes the physical and thermal properties of this specific model: | Property | Specification | | :--- | :--- | | **Dimensions** | 45mm x 45mm x 20mm | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 6.69°C/W (at 100 LFM) | | **Fin Style** | Straight Fin | | **Flow** | Cross-flow capability | --- ### 2. Key Features and Design The ATS-04H-71-C2-R0 is part of the **pushPIN™** series, which focuses on ease of assembly and secure thermal contact. * **Attachment Mechanism:** It uses a push-pin and spring mechanism. This ensures consistent pressure across the thermal interface material (TIM), preventing gaps between the component and the heat sink. * **Thermal Performance:** The "straight fin" design is optimized for environments with forced air cooling. The material (AL6063) provides a good balance between thermal conductivity and weight. * **Blue Anodized Coating:** The blue anodization is not just for aesthetics; it provides surface protection and slightly increases emissivity for better radiant heat transfer. --- ### 3. Electronic Application This part is typically found in the following electronic environments: 1. **Network Hardware:** Cooling high-speed ASICs or FPGAs in switches and routers. 2. **Embedded Systems:** Industrial PCs where high-reliability mounting is required to withstand vibration. 3. **Power Electronics:** Managing heat for Voltage Regulator Modules (VRMs) or power converters. --- ### 4. Thermal Performance Comparison Thermal resistance varies based on the airflow (Measured in Linear Feet per Minute - LFM): | Air Velocity (LFM) | 100 | 200 | 400 | 600 | | :--- | :--- | :--- | :--- | :--- | | **Resistance (°C/W)** | 6.69 | 2.50 | 1.41 | 1.03 |
