The **ATS-19F-73-C3-R0** is a high-performance electronic thermal management component, specifically an **Advanced Thermal Solutions (ATS) push-pin heat sink**. It is designed to dissipate heat from electronic components like CPUs, GPUs, or high-power chipsets. --- ### 1. Technical Specifications | Feature | Specification | | :--- | :--- | | **Product Type** | Heat Sink (High Performance) | | **Attachment Method** | Push-Pin (Plastic or Brass) | | **Material** | Aluminum (Blue Anodized) | | **Thermal Resistance** | 14.71°C/W (Unducted Flow @ 100 LFM) | | **Fin Type** | Straight Fin | | **Dimensions (L x W x H)** | 45mm x 45mm x 10mm | | **Thermal Interface Material (TIM)** | T412 (Pre-applied) | --- ### 2. Detailed Part Breakdown #### A. The Heat Sink Body The unit is manufactured from aluminum, which provides a balance between thermal conductivity and weight. The **Blue Anodized** finish is not just for aesthetics; it provides surface protection against corrosion and increases the emissivity of the metal, slightly improving heat radiation. #### B. The Push-Pin Mechanism Unlike adhesive-based heat sinks, the **ATS-19F series** uses a mechanical push-pin system. * **Spring-Loaded:** Provides consistent pressure (force) against the electronic chip. * **Reliability:** Mechanical mounting is more durable than thermal tape in high-vibration environments or systems with high thermal expansion cycles. * **Compatibility:** Requires pre-drilled holes in the Printed Circuit Board (PCB). #### C. Thermal Interface Material (TIM) The part comes with **T412** pre-applied to the base. * **Purpose:** Fills microscopic air gaps between the chip surface and the heat sink base. * **Conductivity:** T412 is a high-efficiency phase-change or pad material that ensures maximum heat transfer as soon as the component begins to heat up. --- ### 3. Thermal Performance Analysis The efficiency of this part depends heavily on the airflow (LFM - Linear Feet per Minute) within the electronic enclosure: | Airflow (LFM) | Velocity (m/s) | Thermal Resistance (°C/W) | | :--- | :--- | :--- | | 100 | 0.5 | 14.71 | | 300 | 1.5 | 4.70 | | 500 | 2.5 | 3.13 | *Note: As airflow increases, the thermal resistance drops significantly, allowing the part to handle much higher power loads.* --- ### 4.
