20110297142 | WATER HEATING APPARATUS USING SOLAR POWER - A solar power water heating apparatus includes a supporting device for supporting movably a mounting seat provided with a condensing unit on a mounting side thereof for concentrating sunlight onto a heat-conductive tube body in the mounting seat. The tube body absorbs thermal energy from the sunlight concentrated thereonto and transmits the thermal energy to water therein, thereby heating the water. The supporting device includes a disk member mounted rotatably on a hollow base body and driven by a drive unit in the base body to rotate relative to the base body in a central axis of the disk member, and a telescopic rod member and two upright supporting rods interconnecting the mounting seat and the disk member. A control module controls the drive unit and the telescopic rod member based on a solar radiating direction to move the mounting side of the mounting seat to face sunlight. | 12-08-2011 |
