The **ATS-18B-46-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™** product line, designed to provide high cooling efficiency in constrained spaces. ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions Inc. | | **Part Number** | ATS-18B-46-C2-R0 | | **Heat Sink Type** | maxiFLOW | | **Attachment Method** | pushPIN™ | | **Dimensions (L x W x H)** | 37.00mm x 41.00mm x 25.00mm | | **Material** | Aluminum (AL6063) | | **Finish** | Blue Anodized | | **Thermal Resistance** | 2.50°C/W (at 200 LFM) | --- ### Key Electronic & Design Components #### 1. The maxiFLOW™ Fin Pattern The heat sink features a unique **tapered fin design**. Unlike standard straight fins, these are spread out to maximize the surface area exposed to the airflow. This reduces the "pressure drop" and increases the cooling efficiency for high-power electronic components like CPUs, GPUs, or FPGAs. #### 2. pushPIN™ Attachment System This part uses a specialized mounting mechanism: * **Compression Springs:** These ensure constant pressure (Force) is applied between the heat sink and the electronic chip. * **Plastic/Brass Pins:** They lock into pre-drilled holes on the Printed Circuit Board (PCB). * **Benefit:** It provides a secure mechanical fit that survives vibration and mechanical shock better than adhesive tapes. #### 3. Thermal Interface Material (TIM) The "C2" in the part number typically denotes that it comes pre-applied with a **Thermal Interface Material**. * **Purpose:** It fills the microscopic air gaps between the chip surface and the heat sink base. * **Component:** Usually a high-performance phase-change material or thermal grease to ensure maximum heat transfer. #### 4. Material and Coating * **Aluminum 6063:** Chosen for its high thermal conductivity and lightweight properties. * **Blue Anodization:** This is not just for aesthetics; the anodized layer provides increased corrosion resistance and slightly improves "emissivity" (the ability to radiate heat). --- ### Typical Applications * **Telecommunications:** Cooling of high-speed networking chips. * **Embedded Systems:** Industrial computers where airflow might be limited. * **Power Electronics:** Voltage regulators and power modules that generate significant heat.
