The **ATS-18F-137-C2-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of the "push-pin" series designed for efficient thermal management of electronic components like CPUs, GPUs, and other high-heat surface-mount chips. ### 1. Technical Specifications Below are the primary physical and thermal characteristics of the component: | Feature | Specification | | :--- | :--- | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | Push-Pin (Plastic) | | **Dimension (L x W)** | 18mm x 18mm | | **Height** | 7mm | | **Thermal Resistance** | 18.28°C/W (@ 200 LFM) | | **Fin Style** | Fine Pitch Cross-Cut | --- ### 2. Key Electronic Components & Design The functionality of this part is centered around thermodynamics and mechanical stability: #### A. Thermal Interface Material (TIM) The "R0" suffix indicates that the part typically comes pre-applied with a **T766 phase-change material** or a similar thermal pad. This ensures maximum heat transfer by filling microscopic air gaps between the electronic chip surface and the aluminum base. #### B. Attachment Mechanism Instead of adhesive tapes, this model uses a **brass spring-loaded push-pin** system. This is crucial for: * **Constant Pressure:** Ensures the heat sink stays flush against the component. * **Reliability:** Prevents the heat sink from falling off due to mechanical shock or vibration. * **Pre-drilled Holes:** Requires specific hole patterns (2.5mm - 3.0mm) on the PCB. #### C. Cross-Cut Fin Design The fin structure is "cross-cut," meaning it allows for multi-directional airflow. This is ideal for electronic enclosures where the direction of the cooling fan's airflow may not be perfectly aligned with the heat sink. --- ### 3. Typical Applications * **Embedded Systems:** Used on microcontrollers and small-form-factor logic boards. * **Telecommunications:** Cooling for network switches and routers. * **Power Supplies:** Managing heat for voltage regulators (VRMs).
