The **ATS-18F-150-C2-R0** is a high-performance electronic thermal management component, specifically a **Heat Sink** manufactured by *Advanced Thermal Solutions (ATS)*. It belongs to the "maxiFLOW™" series, designed to dissipate heat from integrated circuits (ICs) like CPUs, GPUs, or FPGAs. ### 1. Technical Specifications | Parameter | Specification | | :--- | :--- | | **Part Number** | ATS-18F-150-C2-R0 | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ | | **Thermal Resistance** | 4.82°C/W (Unducted Flow @ 200 LFM) | | **Dimensions (L x W x H)** | 45mm x 45mm x 25mm | | **Airflow Direction** | Vertical/Straight Fin | --- ### 2. Breakdown of the Part Number The nomenclature for ATS heat sinks follows a specific logic: * **ATS**: Prefix for Advanced Thermal Solutions. * **18F**: Indicates the specific fin pattern and series (maxiFLOW). * **150**: Relates to the specific dimensions/profile (Length/Width/Height combination). * **C2**: Refers to the thermal interface material (TIM) or specific coating/material grade. * **R0**: Version/Revision number or specific packaging code. --- ### 3. Key Electronic/Mechanical Features #### A. maxiFLOW™ Design The heat sink features a high-aspect-ratio fin design that maximizes surface area while minimizing pressure drop. This is critical for electronic systems where space is limited but cooling demands are high. #### B. pushPIN™ Attachment Instead of using messy adhesives or weak thermal tape, this part uses a mechanical **pushPIN™** system. * **Spring-loaded mechanism:** Ensures constant, even pressure on the chip. * **Reliability:** Provides better thermal contact and survives higher vibration/shock environments compared to clip-on heat sinks. #### C. Thermal Interface Material (TIM) The "C2" designation often indicates that the part comes pre-applied with a high-performance thermal phase-change material or grease. This eliminates the need for manual application during assembly, reducing the risk of air pockets that hinder heat transfer. --- ### 4. Implementation Example In a circuit design, this part is used to keep a high-power component within its safe **Operating Junction Temperature ($T_j$)**. ```python # Simple Thermal Calculation power_dissipation = 15.0 # Watts ambient_temp = 35.0 # Celsius thermal_resistance = 4.82 # °C/W # Calculate Case Temperature (Estimated) case_temp = ambient_temp + (power_dissipation * thermal_resistance) print(f"Expected Case Temperature: {case_temp}°C") # Output: 107.3°C (May require higher airflow to lower resistance) ```
