The working medium in the pulsating heat pipe flows out from the first outlet pipeline joint 11 of the metal heat absorbing plate 8 of the heat collector 1, flows out into the channel of the metal heat absorbing plate 18 through the flexible pipeline 3, flows in the channel and transfers heat to a heat user through the heat conduction of the metal heat absorbing plate 8. The user can heat the heat-using article through the multifunctional heat-using plate 2 or put the hot-end heating plate into the container which is provided with the heat-using plate to heat the domestic water, thereby meeting the small-range heat use required by daily household life.
A first heat-preserving layer 14 is arranged between a first outer shell 15 of the solar heat collector and a first inner shell 13 of the metal heat-absorbing plate. The solar heat collector 1 is fixed on the storage bracket 5, and a pulley 28 is arranged at the bottom of the storage bracket 5. The storage bracket 5 can be used for adjusting and storing the angle of the solar heat collector 1 so as to achieve the purpose of efficiently utilizing solar radiation and efficiently transferring heat between the solar heat collector 1 and the multifunctional hot plate 2.
In the heat utilization stage, solar energy is absorbed by the solar heat collector 1 and then heats the working medium of the pulsating heat pipe evaporation section 9 of the metal heat absorption plate, so that the working medium is subjected to phase change vaporization, enters the multifunctional heat utilization plate 2 through the flexible pipeline 3, flows in the pulsating heat pipe condensation section 19 of the multifunctional heat utilization plate 2, and conducts heat to a heat user through the heat conduction of the pulsating heat pipe condensation section 18 of the metal heat utilization plate.

When the temperature of the multifunctional heat utilization plate 2 is higher than the phase change temperature of the heat storage medium filled in the multifunctional heat utilization plate, and the heat storage medium is not completely phase-changed, heat enters the medium-temperature porous composite material phase-change heat storage medium, so that heat storage and heat preservation or low-temperature heat utilization are facilitated.
