The invention discloses a reforming hydrogen production reactor of a micro-bump structure with an annular array. The reforming hydrogen production reactor is composed of an inlet cover plate, an evaporation unit, a reaction carrier unit, a heating unit and an outlet cover plate which are stacked up from top to bottom in sequence, wherein reaction fluid flows into the micro-bump structure of the annular array through a plurality of inlets which are arranged into a circle and flows out from the center of circle, so that the distribution uniformity of the reaction fluid in the reaction carrier is improved, and the reaction efficiency of the reactor is favorably improved; the micro-bump structure of the annular array is used as the reaction carrier for the reforming hydrogen production reactor, so that the specific surface area of the reactor is increased, and meanwhile the heat transfer and mass transfer performance of the reaction are improved; the reforming hydrogen production reactor has a compact structure, is convenient to mount and lower in cost, can be widely used in the field of reforming hydrogen production of various alcohols such as hydrocarbon, methanol and alcohol.
