Embodiment

[0046] A method for designing and manufacturing a heat exchange component of an aerospace engine, comprising:

[0047](1) Use the modeling software UG NX7.5 to establish a three-dimensional model of the heat exchange shell. The outline size of the heat exchange shell is Φ50mm×153mm, the outer diameter of the inner wall is Φ34mm, the inner diameter of the outer wall is Φ46mm, and the thickness of the inner and outer walls is 2mm. After the mold is completed, the 3D model of the heat exchange shell is exported to STL format, and the export accuracy is not less than 0.005mm, such as figure 1 shown;

[0048] (2) Use the modeling software UG NX7.5 to create a cylinder entity file with inner and outer diameters of Φ33mm and Φ47mm respectively, and a length of 140mm. This size is slightly larger than the size of the heat exchange shell. According to the pores of the heat exchanger To meet the requirement of 88% efficiency, use 3D_matic software to carry out lattice design on the cyl...
