Technical Specifications The part number follows a specific nomenclature that defines its physical and thermal characteristics. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Advanced Thermal Solutions (ATS) | | **Material** | Aluminum | | **Finish** | Blue Anodized | | **Attachment Method** | pushPIN™ (Spring-loaded pins) | | **Dimensions** | 54mm x 54mm x 15mm | | **Thermal Resistance** | 13.38°C/W (Unducted Flow @ 100 LFM) | | **Base Shape** | Square | --- ### 2. Key Electronic Components & Design The "electronic" functionality of this part is passive, but its design is critical for the stability of active electronic circuits. #### A. The pushPIN™ Attachment Unlike adhesive tapes, this part uses a **pushPIN™ system**. This consists of a plastic or brass pin and a compression spring. * **Purpose:** Ensures consistent pressure between the heat sink and the electronic chip to minimize the thermal interface resistance. * **Reliability:** Prevents the heat sink from shifting during mechanical shock or vibration, which is vital for industrial electronics. #### B. Heat Sink Geometry (Straight Fin) The part uses a **Straight Fin** design. * **Airflow:** Optimized for "ducted" or "open" airflow environments. * **Density:** The fin spacing is calculated to balance surface area with pressure drop, ensuring that even low-speed cooling fans can move air through the fins effectively. #### C. Thermal Interface Material (TIM) The "C2" in the part number often indicates the type of pre-applied Thermal Interface Material or the specific hardware kit. * **Function:** Fills microscopic air gaps between the heat sink base and the electronic component (IC) to facilitate maximum heat transfer. --- ### 3. Common Applications This specific size and thermal profile are generally used for: * **Telecommunications:** Network switches and routers. * **Embedded Systems:** Industrial PCs and motherboards. * **Power Electronics:** Large Voltage Regulators or DC-DC converters. --- ### 4. Comparison of Performance How the part behaves under different airflow conditions (measured in Linear Feet per Minute): | Airflow (LFM) | Thermal Resistance (°C/W) | | :--- | :--- | | 100 (0.5 m/s) | 13.38 | | 300 (1.5 m/s) | 4.10 | | 500 (2.5 m/s) | 2.50 |
