Abstract
The utility model provides a flat-plate type solar water heater with an inversed water tank, which belongs to a solar water heater. The positions of the water tank and a heat collecting plate are inversed. The water tank is positioned below the heat collecting plate and the bottom edge of the heat collecting plate. A circulating pump is installed between the water tank and the heat collecting plate to form a water heating loop with forced circulation. A photocell plate (or a normal ac or a dc power supply) is used as a driving power supply of the circulating pump. The photocell plate is installed on the outer surface of the water tank or one side of the heat collecting plate. The operation of the circulating pump and the water heater is controlled by a water level controller or a temperature controller. When the sunlight exists, the photocell plate automatically works after the water tank is filled with water. The circulating pump is driven to fill the water which is in the water tank into heat collecting pipes to be heated. The water which is heated returns to the water tank through a return pipe. The water is circulated in the way. After the circulating pump stop to operate, the water in the heat collecting plate automatically flows back to the water tank to avoid that the water is frozen in low temperature to damage the heat collecting plate. Therefore, the flat-plate type solar water heater can operate at low temperature through the winter.
