The invention provides a micro-channel phase change cold plate integrating bubble segmentation and damping regulation and control, and relates to the technical field of phase change cooling. When bubbles generated by gas-liquid phase change of a cooling working medium flow through a bubble regulator, a large bubble is segmented into two small bubbles by a bubble segmentation part, and therefore under the condition that the total volume of the bubbles is not changed, the small bubbles are separated into two small bubbles; the bubble surface area is increased, and the latent heat exchange amount on a gas-liquid interface is increased. The divided small bubbles flow along the first flow channel and the second flow channel respectively, and the inner diameters of the first flow channel and the second flow channel are reduced, so that the small bubbles form elongated bubble flow, and the enhanced phase-change heat transfer of a thin liquid film evaporation heat transfer area is increased. And moreover, the interfa
