Example one

As shown in fig. 1 and 2, unlike the previous embodiment, the multifunctional heat sink includes a phase-change energy storage medium, which is round particles 21 having a closed elastic surface layer 211, such as a silicone rubber elastic film with good thermal conductivity. The elastic surface layer is wrapped with a phase-change energy storage medium, such as phase-change energy storage paraffin liquid 212, the particles are arranged in water in a plurality of boxes 22, and different boxes can be arranged in different rooms. The counter weight filler has in the particulate matter, for example iron powder etc. to under certain temperature, this moment the density of particulate matter is equivalent with the density of box water-logging, is in the suspended state in aqueous, when the temperature rose to certain temperature, under the effect of expend with heat and contract with cold principle, the particulate matter inflation, particulate matter density diminishes, and the particulate matter floats upwards in aqueous, when the temperature reduced to certain temperature, the particulate matter dwindles, and particulate matter density grow, and the particulate matter descends in aqueous. Of course, the temperature can be flexibly set by selecting or configuring the phase-change energy storage medium, and the temperature can be changed only by expansion with heat and contraction with cold according to the temperature change and by sinking and floating. It is proposed here to choose paraffin as the phase change medium, since paraffin has a density slightly less than water, and can easily be configured to the same density as water by adding a suitable iron powder, whereas paraffin has an approximately linear change in thermal expansion between 35 and 50 degrees and a certain resistance to pressure, so that the elastic surface layer of the particles does not influence the expansion of the particles.

The box is cylindrical, be provided with coaxial cylinder 23 in the box, the coaxial mesopore 231 that the particulate matter that is provided with intercommunication box upper and lower two parts space can pass in cylinder middle part, leave the ring chamber 24 that the particulate matter can pass between cylinder lateral wall and the box inner wall. The inner wall of said central hole is provided with heating means 25, for example a heating resistor coiled in a spring-like manner. The boxes are communicated through pipelines, the pipelines communicated with the boxes comprise an upper pipeline 26 communicated with the upper space of the boxes and a lower pipeline 27 communicated with the lower space of the boxes, and the particulate matter conveying device is a conveying pump 28 arranged on the upper pipeline and the lower pipeline. The upper end of cylinder is toper end 232, the lower extreme of cylinder has conical indent 233 to the particulate matter rises from the mesopore, and descends from the ring chamber in the outside, thereby does benefit to the heating of particulate matter and with the heat exchange of box inner wall, the pipeline is convenient for about to the transfer of upper and lower part particulate matter, more is favorable to carrying out quick heating to the particulate matter at individual position in the box. The pipeline is provided with a control valve 29 for controlling the communication of the pipeline, and the control valve is preferably a valve with good heat insulation. The upper and lower pipelines are provided with filter valves 30, which allow water to pass through but prevent particles from passing through, so as to adjust the amount of particles in different boxes, for example, the lower pipeline is closed and the upper pipeline is opened, so that heated particles can continuously enter the boxes and cannot be discharged from the lower pipeline.

Heating resistance wires 31 can also be arranged on the upper and lower pipelines so as to provide auxiliary heating.
