研究目的
To develop a new housing for the transceiver of an active phased array antenna with a built-in cooling channel, ensuring effective cooling of the active elements, compatibility with selective laser melting (SLM), and easy removal of the powder remaining in the channels after three-dimensional printing.
研究成果
The study demonstrated the feasibility of manufacturing complex parts with built-in cooling channels by additive technology, specifically SLM. The housing produced met quality standards and showed promise for use in advanced radar systems. Future work will focus on optimizing printing conditions to minimize residual deformation and testing thermal mockups to confirm the cooling system's efficiency.
研究不足
The research identified significant residual stress in the sintered material during the manufacturing process, leading to geometric errors such as the arched geometry of the lower housing face. Future research will focus on selecting optimal printing conditions to decrease residual deformation.
1：Experimental Design and Method Selection:
The housing geometry was developed based on preliminary hydrodynamic calculations to meet three basic requirements: effective cooling, compatibility with SLM, and easy powder removal.
2：Sample Selection and Data Sources:
A prototype of the transceiver housing was manufactured on a Renishaw AM400 system by SLM from AlSi10Mg alloy powder.
3：List of Experimental Equipment and Materials:
Renishaw AM400 system, AlSi10Mg alloy powder, Faro Fusion Arm measuring instrument, GE S240 Phoenix V|tome|x tomograph.
4：Experimental Procedures and Operational Workflow:
The housing was produced at an angle of 45° to minimize printing in the down-skin regions, with the temperature of the working platform maintained at 150°С and the argon supplied at 35°С. After manufacturing, the part was heated, cut, and subjected to shot blasting.
5：Data Analysis Methods:
The printed samples were subjected to physicomechanical tests, and the external and internal housing geometry was investigated using the Faro Fusion Arm and GE S240 Phoenix V|tome|x tomograph.
