The invention provides a gas-liquid two-phase flow cold plate and a cooling method, relates to the field of cooling of high-power electronic devices, and solves the problem of poor heat exchange effect caused by non-uniform distribution and easy backflow of gas-liquid two-phase flow in a heat exchange channel. The gas-liquid two-phase flow cold plate comprises a plate body, an inlet mixing cavity and heat exchange micro-channels are formed in the plate body, the inlet mixing cavity is communicated with inlets of all the heat exchange micro-channels, a plurality of micro-columns are arranged in the inlet mixing cavity and arranged at intervals in the fluid flowing direction, and the micro-columns are communicated with the heat exchange micro-channels. The bubble breaking device is used for breaking bubbles in gas-liquid two-phase mixed fluid in the inlet mixing cavity and can prevent the mixed fluid from flowing back. The micro-column bodies can restrain the pulsating backflow effect generated by rapid phase c
