The invention discloses a manufacturing method of a liquid cooling plate of an array
microstructure. The manufacturing method comprises the following steps: S1, modeling the liquid cooling plate, and importing Magics
software to repair the liquid cooling plate; s2, based on the
internal cavity structure of the liquid cooling plate, a direction-finding placement mode is adopted; s3, according to the scanning
layer thickness agreed by the forming process parameters, the
slice thickness is set, data is imported into special
data processing software, proper process parameters are selected, and a printing task is exported; s4, a printing task is imported into printing equipment, a proper gas type is selected, and regional scanning
processing is started; and S5, printing is completed, redundant
powder and an auxiliary support are cleaned, and heat treatment is conducted after the supporting face is ground and polished. Workpieces are printed through the
selective laser melting technology, the product quality is kept, and meanwhile the yield is increased. The structure is simplified and the weight is greatly reduced through the capillary protrusions correspondingly arranged in the cold flow cavity in a staggered mode, heat exchange is improved, and meanwhile due to the fact that the integrally-formed structure is lower in strength and
heat resistance at the connecting position.
