The **ATS-H1-73-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 "maxiFLOW™" product line, designed to provide efficient cooling for electronic components in high-airflow environments. --- ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum (Black Anodized) | | **Attachment Method** | pushPIN™ (Spring-loaded) | | **Thermal Resistance** | 3.32°C/W (at 200 LFM) | | **Dimensions (L x W x H)** | 45mm x 45mm x 10mm | | **Fin Style** | Straight / maxiFLOW™ | --- ### Key Design Components #### 1. Heat Sink Geometry (maxiFLOW™) The "maxiFLOW" design features a flared fin structure. Unlike standard straight-fin heat sinks, these fins are angled to maximize the surface area and improve the airflow intake. This design reduces pressure drop and increases the heat dissipation capacity, making it ideal for high-density PCB layouts. #### 2. Attachment Mechanism: pushPIN™ This part utilizes the **pushPIN™** system for mounting to the Printed Circuit Board (PCB). * **Ease of Use:** It allows for quick installation without the need for tools. * **Reliability:** The brass or plastic pins paired with a stainless steel spring provide a specific "clamping force" (pressure) on the electronic component (like a CPU or FPGA), ensuring optimal thermal contact. #### 3. Thermal Interface Material (TIM) The "R0" at the end of the part number typically indicates the pre-applied thermal material. In this configuration, it usually comes with **T766** phase-change material or a high-performance thermal pad, which fills microscopic air gaps between the heat sink and the chip. --- ### Applications The ATS-H1-73-C2-R0 is commonly used to cool high-heat emitting components such as: * **ASICs and FPGAs:** Used in telecommunications and data centers. * **Processors (CPUs/GPUs):** For embedded computing systems. * **Power Electronics:** Voltage regulators and power converters. --- ### Thermal Performance Overview As airflow increases (measured in Linear Feet per Minute - LFM), the thermal resistance decreases: | Air Velocity (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 | 5.03 | | 200 | 3.32 | | 400 | 2.50 | | 600 | 2.11 |
