Heat energy recycling system

The utility model discloses a heat energy recycling system to the low problem of prior art heat exchange efficiency, provides following technical scheme, including the box, be equipped with in the boxfrom supreme logical subcooled water's cold water pipe down, the intercommunication has the hollow heat exchange layers in a plurality of inside on the cold water pipe, is equipped with in the box tobe used for the spray set to heat exchange layers's upper surface hot water spraying, and heat exchange layers's outer edge is equipped with the guide plate that is used for hot water water conservancy diversion to next heat exchange layers's the upper surface that flows down from the heat exchange layers border, cold water gets into from the cold water pipe lower extreme, and then from the entering heat exchange layers supreme down, finally flows from the upper end of cold water pipe, and hot water sprays to the heat exchange layers on through spray set, and hot water carries out the heat exchange through heat exchan
