The invention discloses a heat transfer enhanced heat pump phase-change heat storage device, which mainly comprises supporting plates (5), a plurality of independent harmonica plate plate-type heat exchangers (6), fins (2), a liquid collection header pipe and a liquid collection pipe, wherein one of the harmonica plate plate-type heat exchangers (6) is arranged between each two supporting plates (5); the fins (2) are arranged between the harmonica plate plate-type heat exchangers (6) and the supporting plates (5); a phase-change heat storage material (15) is filled in gaps among the harmonica plate plate-type heat exchangers (6), the supporting plates (5) and the fins (2); the harmonica plate plate-type heat exchangers (6) consist of harmonica plate sheet units extruded with a plurality of flow passages (14); and outlets and inlets of the flow passages (14) are in brazed connection with the liquid collection pipe, and then are communicated with the liquid collection header pipe through the liquid collection pipe. The heat transfer enhanced heat pump phase-change heat storage device realizes the storage and the release of heat through the heat exchange between the heat exchangers and the phase-change heat storage material, and forms a heat pump phase-change heat storage device integrated with heat storage and heat supply. The heat pump phase-change heat storage device has the advantages of small volume, light weight, simple structure, low cost, low power consumption, safety, reliability and the like.
