Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions, Inc. (ATS) | | **Part Series** | maxiFLOW™ | | **Thermal Resistance** | 3.52° C/W (@ 200 LFM) | | **Material** | Aluminum (Blue Anodized) | | **Attachment Method** | pushPIN™ (Brass Pins) | | **Spring Type** | Stainless Steel | | **Dimensions (L x W x H)** | 36.83mm x 36.83mm x 17.78mm | | **Thermal Interface Material** | T412 (Phase Change Material) | --- ### 2. Component Breakdown #### A. The Heat Sink Body (Fin Design) The ATS-18D-33-C3-R0 utilizes a **Spread Fin** design. Unlike standard straight-fin heat sinks, the maxiFLOW™ profile features a flared fin structure. * **Purpose:** This design increases the surface area and maximizes air turbulence, significantly improving cooling efficiency in low-airflow environments. * **Material:** Made from high-grade aluminum with a **Blue Anodized** finish for enhanced durability and corrosion resistance. #### B. The pushPIN™ Attachment System Instead of using messy adhesives or simple clips, this model uses a proprietary **pushPIN™** system. * **Mechanism:** It consists of a brass pin and a stainless steel spring. * **Benefit:** This provides consistent pressure (load) across the electronic component, ensuring maximum thermal contact while allowing for easy installation and removal without damaging the PCB. #### C. Thermal Interface Material (TIM) The bottom of the heat sink is pre-applied with **T412**. * **Function:** T412 is a high-performance thermal pad that fills microscopic air gaps between the component (chip) and the heat sink. * **Efficiency:** It ensures minimal thermal impedance, allowing heat to flow efficiently away from the silicon. --- ### 3. Thermal Performance Metrics Thermal resistance indicates how effectively the part dissipates heat. Lower numbers are better. * **@ 200 LFM (Linear Feet per Minute):** 3.52 °C/W * **@ 400 LFM:** 2.15 °C/W * **@ 600 LFM:** 1.65 °C/W --- ### 4. Applications This electronic part is typically found in: 1. **Network Switches/Routers:** Cooling high-speed processors. 2. **Embedded Systems:** Industrial PCs where space is limited but heat is high. 3. **Power Supplies:** Dissipating heat from MOSFETs or voltage regulators.
