Directed Air Cooling Channel for Stepper Motor Drivers (MKS Gen L V1.0) · 模型 125679
This project presents a dedicated air cooling channel designed specifically for the MKS Gen L V1.0 control board. The system directs airflow precisely beneath the stepper motor drivers, ensuring efficient and targeted thermal management. The cooling concept is based on guiding air from a 40 mm centrifugal (radial) fan directly toward the heat-generating components, while avoiding disturbances from surrounding parts on the mainboard. This approach minimizes unwanted turbulence and improves overall cooling efficiency. To enhance heat dissipation, thermal heat sinks are installed on both sides of each driver module: one on the backside (label side) and one directly on the driver IC, where most of the heat is generated due to switching losses. This dual-sided cooling configuration maximizes convective heat transfer. In order to integrate the air cooling channel into the system, custom extension PCBs were developed. These extension boards elevate the driver modules and create the necessary clearance for the airflow path. The extension PCBs are included in the STEP file to provide a complete overview of the mechanical and electrical integration. The adapter PCB connects to the mainboard using pin headers, while the driver side utilizes female pin headers. The 3D-printed structure is designed to securely accommodate these connectors and ensure proper alignment between the duct, extension boards, and driver modules. The cooling channel is equipped with a 40 mm radial fan, which is mounted using four screws and secured by an additional lid. This assembly ensures stable positioning of the fan and reliable airflow delivery into the duct. With this design, cool air is directed exclusively toward the heat-producing stepper drivers. By isolating the airflow path from other mainboard components, the system avoids unnecessary turbulence, reduces dust accumulation, and minimizes the need for frequent cleaning and maintenance. This solution provides an effective and compact approach for improving thermal performance on the MKS Gen L V1.0 board in space-constrained electronic systems.
