Method for smearing liquid metal on heat generating surface or heat conducting surface

A method for smearing liquid metal on a heat generating surface or a heat conducting surface is suitable for coating the heat generating surface or the heat conducting surface of a target object, andthe method for smearing comprises an squeezing injecting step and a uniform coating step. In the squeezing injecting step, the liquid metal is squeezed out of an injector into the heat generating surface, the heat conducting surface or other containers. In the uniform coating step, a tool is in contact with the liquid metal, force is applied to the liquid metal to destroy the cohesion of the liquid metal, and then the tool is operated to perform smearing back and forth so that the heat generating surface or the heat conducting surface is uniformly coated with the liquid metal. The cohesion ofthe liquid metal is destroyed by applying the external force, so that the liquid metal is not spherical any more, and finally, the heat generating surface or the heat conducting surface of the targetobject is uniformly coated
