1. A desalination apparatus utilizing solar energy comprising:a heat collector for heating a heating medium with solar energy, an evaporation can, comprising: a heat exchanger associated with the heat collector, said heat exchanger comprising: a heat transfer tube containing the heating medium, said heat transfer tube extending into and submerged in raw water in the evaporation can, for providing heat exchange between the heating medium and the raw water resulting in the generation of water vapor, a raw water tank, comprising: a condenser; and another heat transfer tube associating the condenser with the evaporation can, which receives water vapor from the evaporation can, said another heat transfer tube being submerged in raw water in the raw water tank to cool the water vapor by subjecting the water vapor and raw water in the raw water tank to heat exchange thereby obtaining distilled water, a distilled water tank for storing the distilled water, a vacuum means for evacuating the evaporation can and depressurizing an inside of the evaporation can so as to promote generation of water vapor in the evaporation can, and raw water supply means for supplying raw water to the evaporation can, wherein said heating medium is circulated by an action of thermosiphon in which said heating medium is heated in the solar heat collector to form vapor, which is then cooled to become liquid in the evaporation can.
