This invention is for the provision of water distillation device and the method using the solar heat. More particularly, the solar heat distillation device comprises; The solar heat collector with cylindrical parabolic reflective mirror which is formed with the fixed focus axis of reflection surface where the sun light is concentrated by the reflection and the cylindrical parabolic reflective mirror is able to track the sun by revolving east to west around fixed axis of reflection surface; And the expansion water pipe line on the focus axis which expand water by solar heating; and the condensation water tank on the focus axis of reflection surface which condensate the expanded water from the expansion water pipe line; also the evaporation water tank on the focus axis of reflection surface which generate steam by heating the water in the evaporation water tank with solar heat and high temperature steam; And the steam reheating pipe line on the axis of reflection surface which provide high temperature steam by heating the steam from the evaporation water tank with solar heat; With the above solar heat distillation device, it is characterized that comprises; The heat exchanger which perform heat exchange between the water to distill and the distilled water for preheating the water to distill and cooling the distilled water; and the hand pump to fill water in the solar heat device at the initial operation. Accordingly, this invention is complex process of pumping, heat exchanging, steam reheating and evaporation to distill seawater or all sorts of water in high efficiency by means of only with solar energy without any energy such as oil or electricity.
