The utility model discloses a novel phase change heat storage device, comprising a housing, wherein the housing is internally provided with a lining; an insulating layer is disposed between the lining and the housing; the lining is internally filled in with a phase change material; a coiled pipe is embedded in the phase change material; the inlet and outlet of the coiled pipe both extend out of the lining and are respectively welded with and communicate with a main water inflow pipe and a main water outflow pipe, so all welds between the coiled pipe and the main water inflow pipe and main water outflow pipe are positioned outside the lining and are not soaked by the phase change material. The lining is provided with at least one partition board; the partition board divides the inner space of the lining into independent spaces such that the phase change material is respectively positioned in the independent spaces divided by the partition board. Compared with the prior art, the utility model has a simple and novel structure design, solves the defects of existing phase change heat storage devices, greatly improves the heat exchange effect of the phase change heat storage device, reduces the production cost of the device, and prolongs the service life of the device.
