the shell structure is mainly used to realize equipment enclosure protection. for some equipment sensitive to thermal environment, the heat generated in the running state needs to be dissipated through the shell to ensure stable operation. that requires the shell structure to achieve active cooling.
traditional solutions
the introduction of cooling medium is often used to realize active cooling and realize heat exchange in the environment through heat conduction and convection. the layout of cooling channel has great influence on heat dissipation efficiency---traditional cooling channels need to be machined and drilled, the straight channel is single body, the transition between the flow channels needs to be realized by cross drilling in different directions. finally, the plug is welded and sealed, the flow channel configuration is limited by process, so, he structure in the plug area is easy to leak due to weld failure.
3d printing and structure optimization
through the layout optimization and analysis of cooling channel, it can help parts achieve more efficient cooling. at the same time, the smooth connection of the runner can enhance the circulation efficiency of cooling medium. the whole structure is formed in one piece, it is no need for secondary welding of plug and runner area, effectively reducing the risk of product defect.
