Description
Technical Field
The utility model relates to a paint apparatus, especially relate to a device of paining of liquid metal is exclusively used in.
Background
The liquid metal is a low melting point alloy which is liquid at normal temperature and has fluidity, and has the advantages of stable property, difficult volatilization, safety, no toxicity and the like, and the atomic structure of the liquid metal is more similar to that of the common solid metal but is more similar to crystalline liquid, so that the liquid metal has higher heat conduction capacity and specific heat capacity, even higher than that of the traditional Silicone Grease (Silicone Grease), and therefore, the liquid metal is often used as a high-power radiator of mechanical tools or electronic products and applied to the field of heat conduction. The gallium-based liquid alloy is one of common liquid metals, the composition of the gallium-based liquid alloy is gallium-indium-tin alloy, gallium accounts for more than half of the components of the gallium, the gallium is light blue metal, the melting point of the gallium is very low, the boiling point of the gallium is very high, the gallium is changed into silvery white liquid at 29.76 ℃, the liquid gallium has the tendency of being obviously overcooled and can be easily cooled to 0 ℃ without solidification, the characteristic enables the gallium to be very suitable for being used as liquid metal for cooling and heat conduction, and the stability of the gallium-based liquid alloy is superior to that of heat conduction silica gel which is easy to age and dry.
The liquid metal surface tension of gallium, indium and tin is 718mN/m, 556mN/m and 865mN/m respectively, compared with the cohesion of ordinary water is only 72.75mN/m, the liquid metal has obviously higher surface tension, the surface tension is the cohesion caused by Vandertile force among molecules, which can promote the liquid to reduce the surface area of the liquid so as to reduce the chemical potential which is not met, because the sphere has the outer surface with the minimum area under the same volume, under the condition of no external force, the liquid is always spherical under the equilibrium state, in other words, the liquid metal with high surface tension can not completely contact the surface of the CPU, GPU or radiator because of the stronger cohesion when being coated on the surface of the CPU, GPU or radiator to be used as a heat conduction cooling agent, and the heat conduction capability is broken down.
Furthermore, if the CPU, GPU or heat sink is coated with the liquid metal before shipping, the liquid metal needs to be uniformly coated on the heating surface of the target object in a very short time in order to match with a fast automated process, so how to overcome the cohesion in a very short time to uniformly coat the liquid metal is a long-standing problem in the art; referring to fig. 1, in taiwan patent application No. 108107395, the inventor of the present invention uses a bar-shaped smearing tool 11 to press the liquid metal 2 to break the cohesion of the liquid metal, and smears the liquid metal 2 on the heating surface or the heat conducting surface by smearing back and forth. However, in this applicator 11, the natural fiber or synthetic fiber cloth 13 needs to be bound to the front end of the applicator 11 by the elastic band 12, which is difficult to remove and replace, and the natural fiber or synthetic fiber cloth 13 is easy to fall off or deviate during the application of force, so there is room for improvement.
