Abstract

The invention discloses a phase change heat storage device. The phase change heat storage device comprises a metal shell. The inner side wall of the metal shell is covered with a heat insulating layer. A phase change heat storage module is arranged in the metal shell. The phase change heat storage module comprises a metal frame, foam metal arranged in the closed metal frame in a filling mode, anda phase change material arranged in the foam metal in a filling mode. A plurality of electric heating wires distributed evenly and a heat exchange coil arranged in a baffling mode are further arrangedin the metal shell, wherein the electric heating wires are connected with an external power source through an electric wire; a water inlet end of the heat exchange coil is connected with a water inlet branch pipe; and a water outlet end of the heat exchange coil is connected with a water outlet branch pipe. The phase change heat storage device has the functions of heating, heat storage and hot water supply, the principle of phase change heat storage is adopted, meanwhile, a heat transfer framework is formed through the foam metal, thus, the heat conductivity of the heat storage device is effectively improved, a heat storage box is arranged modularly, and manufacturing and maintaining of the device are facilitated.
