The **ATS-16D-46-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by Advanced Thermal Solutions (ATS). It is part of the "pushPIN™" series, designed for precision cooling of electronic components like CPUs, GPUs, and power transistors. --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Part Number** | ATS-16D-46-C2-R0 | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded plastic pins) | | **Thermal Resistance** | 11.57 °C/W (at 100 LFM) | | **Dimensions (L x W x H)** | 25mm x 25mm x 15mm | | **Fin Style** | High-Flow (Straight Fins) | --- ### 2. Breakdown of the Part Number The alphanumeric code follows a specific naming convention used by ATS to describe the physical and thermal properties: * **ATS-16:** Refers to the series and specific internal geometry. * **D:** Often denotes the specific fin pattern or spacing. * **46:** This is the height/configuration index. * **C2:** Indicates the **thermal interface material (TIM)**. In this case, "C2" usually signifies **T766 Phase Change Material**, which optimizes heat transfer from the chip to the aluminum. * **R0:** Refers to the RoHS compliance and the specific revision/packaging version. --- ### 3. Key Electronic Functions The ATS-16D-46-C2-R0 serves several critical functions in an electronic assembly: 1. **Passive Cooling:** It increases the surface area of the heat-generating component, allowing air to carry away heat more effectively. 2. **Mechanical Tension:** The **pushPIN™** mechanism ensures constant, even pressure across the surface of the electronic chip, which prevents air gaps and ensures the Thermal Interface Material (TIM) works efficiently. 3. **Cross-Flow Optimization:** The straight-fin design is optimized for environments where there is forced airflow (fans), allowing air to pass through the fins with minimal resistance. --- ### 4. Implementation Code Example In thermal modeling software (like Python-based simulation), you might represent this part's thermal resistance properties as follows: ```python class HeatSink: def __init__(self, model, thermal_resistance, airflow_lfm): self.model = model self.resistance = thermal_resistance # °C/W self.airflow = airflow_lfm # Linear Feet per Minute # Instance for ATS-16D-46-C2-R0 ats_heatsink = HeatSink("ATS-16D-46-C2-R0", 11.57, 100) def calculate_temp_rise(power_watts): return power_watts * ats_heatsink.resistance # If the chip dissipates 2 Watts rise = calculate_temp_rise(2) print(f"Temperature rise above ambient: {rise}°C") ```
