The screw forms a longitudinal heat conduction structure in the composite body, so that the longitudinal heat conduction of the material with good horizontal heat conduction and poor longitudinal heat conduction can be obviously enhanced. Meanwhile, the screw structure can also enhance the connection of high-heat-conduction materials with the outer-layer substrate and the cover plate, and reduce the interface thermal resistance. The method is simple and reliable, low in cost and strong in operability, and the complex body manufactured by the method is high in thermal conductivity, low in density, high in strength and controllable in thickness, avoids the defects that high-heat-conducting materials are easy to wear, drop slag, low in strength and the like, and can be applied to heat dissipation structures of various substrates, cold plates, case shells and the like.)
