Heat exchange structure based on variable-period minimum curved surface, heat exchanger and manufacturing method
The invention discloses a heat exchange structure based on a variable-period minimum curved surface, a heat exchanger and a manufacturing method, and belongs to the field of aerospace power equipment and functional composite materials. In the aspect of the structure, the heat exchange structure comprises the cold fluid flow channel and the hot fluid flow channel which are isolated from each other and staggered in the three-dimensional space, the internal structures of the cold fluid flow channel and the hot fluid flow channel are both variable-period minimum curved surface structures, and the heat exchange structure is small in pressure loss and high in heat exchange efficiency. In the aspect of materials, an interface gradual change material is developed to form an interface gradual change composite structure, the components of the interface gradual change composite structure on the contact surfaces of different materials are gradually changed, and the interface gradual change composite structure has good strength, toughness and corrosion resistance and can bear high cyclic thermal hardness; non-uniform expansion stress caused by temperature difference can be reduced or eliminated, and the service life of the heat exchanger is prolonged.
