Preparation method of heat-conducting fiber radiator

A preparation method of a heat-conducting fiber radiator belongs to the technical field of radiator preparation. The method comprises the following steps: carrying out surface treatment on heat-conducting fibers, changing the surface activity of the heat-conducting fibers, and depositing a layer of matrix metal material or a heat-conducting material with good compatibility with the matrix metal material on the surfaces of the fibers to form the heat-conducting fibers with large specific surface area; preparing a heat-conducting fluid by adopting an oxygen-free hot melting method, immersing the treated heat-conducting fibers with the large specific surface area into the heat-conducting fluid in a specific pattern distribution structure, and cooling and solidifying the heat-conducting fluid to form a metal matrix, so as to obtain a cooling fin blank; scattering free sections of the heat conduction fiber bundles on the surface of the blank to form a good air convection channel and a super-large heat dissipation
