<p>A pressurized solar water heater, which belongs to solar energy application technology field. The water heater comprises a water storage tank and a solar heat collection device with filling opening and liquid port. The bottom of the inner tank consists of a heat exchange cavity with water inlet and water outlet. The upper surface of the heat exchange cavity is coplanar with the bottom surface of the inner tank. Connect filling opening and return opening of the solar heat collection device to the water inlet and water outlet of the said heat exchange cavity separately, thus forming a cyclical loop. The structure of this invention is relatively simple, which is not reducing the water storage space of the inner tank. And as the high temperature water in the inner tank and heat exchange cavity has a upward trend and the low temperature water has a dropping trend, the upper coplanar surface connects with the water with the lowest temperature in the inner tank all the time and the lower surface connects with the water with the highest temperature in the heat exchange cavity all the time. Then the upper surface and lower surface of the coplanar surface have a maximum difference in temperature to obtain best heat exchange efficiency, increasing the hot water supply greatly.</p> |
