AI Technical Summary

Technical Problem

After the height of the support columns manufactured by conventional production methods increases in the VC heat-smoothing plate, they are prone to collapse and fall off, resulting in unstable performance and affecting the heat dissipation effect and service life.

Method used

The integrated supporting copper powder column production process is adopted, through the rational design of the mold structure and the copper column insertion step, the powder making tanks and channels in the powder storage unit are used to fill the mixed powder and insert the copper column for firing, forming a tightly combined support column structure, and optimizing the capillary liquid absorbing core with nano-carbon tubes and other components.

Benefits of technology

It improves the structural stability and thermal conductivity of the support column, enhances the heat dissipation performance and service life of the VC heat-efficient plate, adapts to different height requirements, and meets the heat dissipation needs of high-power consumption equipment.

Abstract

The invention relates to the technical processing field of copper powder columns, in particular to a production process of an integrated supporting copper powder column and a VC vapor chamber, and the production process comprises the following steps that a mold is provided with a plurality of powder containing units, each powder containing unit is provided with a plurality of powder preparing grooves, and the adjacent powder preparing grooves are connected through a channel; the preparation method comprises the following steps: uniformly stirring copper powder, bismuth trioxide, antimony trioxide, silver, rosin resin, an adhesive, carbon nanotubes, a pore forming agent and water to obtain mixed powder; filling the mixed powder into a powder making groove and a channel; inserting the mixed powder into the center of the powder making tank filled with the mixed powder to obtain a pre-fired product; and preheating the pre-fired product in an environment with the temperature of 200-300 DEG C, preserving heat for 40-60 minutes at the temperature of 600-800 DEG C, preserving heat for 2-3 hours at the temperature of 1070-1100 DEG C, cooling to 20-30 DEG C, and demolding to obtain a finished product. Through the design of the powder containing unit of the mold, copper column inserting firing is matched after powder filling, an integrated supporting structure is formed, the overall stability of the supporting column is enhanced, different height requirements are met, collapse and falling are avoided, and the use stability of the vapor chamber is guaranteed.
