Abstract

PURPOSE: To prevent solar heated liquid from circulating reversely when the liquid temperature in the solar collector becomes lower than that in the heat storage during the night, by adding a sealing liquid to the heat carrying liquid.
CONSTITUTION: When a solar water heater receives sunbeams from the direction A, the heat collecting liquid in a heat collector 5 with a built-in partition plate 2 is heated and its density becomes smaller than that of heat collecting liquid in a heat storage 6, which makes the liquid circulate to the arrow direction to store hot water in the storage unit 6. When the outdoor temperature drops in the night, the heat collector 5 functions as a radiator and the heat collecting liquid circulates reversely to lose its heat collected. The heat collecting liquid X is filled below an interface 7 and a sealing liquid, having a smaller density than that of the former liquid, is filled above the interface 7, and the heat collecting liquid is circulated only when its temperature exceeds that in the heat storage unit 6.
