The **ATS-04H-28-C3-R0** is a high-performance heat sink manufactured by **Advanced Thermal Solutions (ATS)**. It is part of their "push-pin" attachment series, specifically designed for cooling electronic components like CPUs, GPUs, and power modules. --- ### 1. Technical Specifications The following table summarizes the physical and thermal properties of this component: | Parameter | Specification | | :--- | :--- | | **Dimensions (L x W x H)** | 40mm x 40mm x 25mm | | **Material** | Aluminum (AL6063) | | **Fin Style** | Square Fin (Cross-cut) | | **Attachment Type** | Push-Pin (Brass, 4.3mm) | | **Spring Type** | Compression Spring | | **Thermal Interface (TIM)** | T412 (Pre-applied) | | **Finish** | Blue Anodized | --- ### 2. Key Features & Design * **Square Fin Pattern:** The cross-cut fin design creates a larger surface area while allowing for multi-directional airflow. This is ideal for systems where the direction of air from the cooling fan might change or is turbulent. * **Push-Pin Mounting:** This model uses a mechanical mounting system consisting of a brass pin and a compression spring. This provides a specific, consistent pressure against the component, ensuring optimal heat transfer. * **Material Efficiency:** Made from Aluminum 6063, it balances weight and thermal conductivity effectively. The blue anodized finish provides corrosion resistance and increased emissivity. * **Pre-applied TIM:** It comes with a T412 thermal interface material already applied to the base, which simplifies the assembly process in a manufacturing environment. --- ### 3. Thermal Performance The efficiency of the heat sink depends on the airflow velocity (measured in Linear Feet per Minute - LFM): * **Unducted Flow (Thermal Resistance):** * Approx. **10.62 °C/W** at 200 LFM. * Approx. **3.65 °C/W** at 600 LFM. * **Pressure Drop:** As airflow increases, the resistance to that air (pressure drop) also increases, which is a critical factor when selecting a cooling fan. --- ### 4. Part Number Breakdown Understanding the ATS naming convention for this part: * **ATS:** Manufacturer (Advanced Thermal Solutions). * **04:** Series/Attachment type. * **H:** High performance. * **28:** Specific footprint/geometry identifier. * **C3:** Finish and specific kit options. * **R0:** Revision status.
