Laminated sheet sweating and cooling structure

A laminated sheet sweating and cooling structure can be formed through a selective laser melting 3D printing technology and comprises a porous surface layer, a solid base plate and a filler neck. A working medium conveying cavity channel is formed in the solid substrate, and a working medium inlet is formed in the center of the bottom; the outer wall surface of the porous surface layer is a to-be-cooled surface, and the inner wall surface is in contact with a working medium; during working, a cooling working medium enters the conveying cavity channel from the working medium inlet, reaches the porous surface layer at the tail end and seeps out of the outer wall surface through micropores in the porous surface layer; the filler neck is connected with the working medium inlet and is directly formed through 3D printing or fixedly connected with the solid base plate in a welding mode. The design and the process are integrated, the working medium transportation requirement is met, and the process powder cleaning re
