The utility model discloses a flow dividing-converging type rectangular micro-channel heat exchanger system, belongs to the technical field of heat dissipation, and solves the problem that the heat exchange effect is inhibited when a flowing working medium thermal boundary layer is fully developed. The system comprises a micro-channel substrate, and is characterized in that the micro-channel substrate comprises a plurality of micro-channels which are arranged in parallel at intervals in an array mode, the cross section of each micro-channel in the height direction is rectangular, a plurality of shunting-converging micro-channels are periodically arranged on any two adjacent micro-channels of the micro-channels in a staggered mode, the heat exchange area can be obviously increased, and the heat exchange efficiency is improved. And meanwhile, normal flowing of fluid is destroyed, turbulent flow is enhanced, and enhanced heat exchange is achieved. And meanwhile, the start of the shunting-converging micro-channel
