Breakdown of the Part Number Advanced Thermal Solutions uses a structured nomenclature. Here is the breakdown for the **ATS-20D-82-C2-R0**: * **ATS**: Manufacturer (Advanced Thermal Solutions). * **20**: Series (typically refers to the attachment style and fin geometry). * **D**: Compression Spring / Push-Pin attachment style. * **82**: Specific dimensional profile/designation for the 30x30mm footprint. * **C2**: Finish code (indicates Blue Anodized). * **R0**: Revision code or RoHS compliance indicator. --- ### 3. Key Electronic Cooling Features #### A. The "push-pin" Mechanism The **-D-** and **Push-Pin** designation indicates that the heat sink is mounted via pre-drilled holes in the PCB. This provides: * **Consistent Pressure:** The compression springs ensure a uniform load on the electronic component, optimizing the thermal interface. * **Reliability:** Unlike adhesive tapes, push-pins are more secure in high-vibration environments. #### B. Thermal Interface Material (TIM) The "R0" variants often come with a pre-applied **Phase Change Material (PCM)** or high-performance thermal pad on the base. This eliminates the air gap between the electronic chip and the aluminum fins, ensuring efficient heat transfer. #### C. Straight Fin Design The straight fin geometry is optimized for **forced-air cooling**. It allows air from a system fan to pass through the channels with minimal pressure drop, effectively wicking heat away from the semiconductor junction. --- ### 4. Typical Applications * **Network Switches:** Cooling ASICs and FPGA chips. * **Embedded Systems:** Industrial PCs where space is limited but heat density is high. * **Power Supplies:** Cooling MOSFETs or power regulators.
