Abstract
A solar energy intermediate temperature phase transition heat accumulation device consists of a solar energy steam heat collection device and a water-storage type phase transition heat accumulation vessel. The solar energy steam heat collection device consists of a vacuum heat collection tube and a header box connected and matched with the heat collection tube. The solar energy intermediate temperature phase transition heat accumulation device is characterized in that the horizontal error of the two ends of the heat collection tube is less that plus-minus 35 mm, the opening of the heat collection tube contains water-blocking materials, the header box is provided with a steam tube communicated with a heat exchanger arranged in the external water-storage type phase transition heat accumulation vessel, and the water-storage type phase transition heat accumulation vessel contains a phase transition heat accumulation ball. The solar energy intermediate temperature phase transition heat accumulation device has the advantages that the heat collection tube is horizontally arranged, so that states and performance of each part of the heat collection tube along the axis are uniform. The distance between the heat-affected area of the heat collection tube and the storage water is shortened, and additionally an inner glass tube can be directly utilized to conduct heat instead of utilizing capillary materials to lift water. The water blocking materials enable water to enter the heat collection tube and accumulate as usual when the header box is obliquely arranged. The water-storage type heat accumulation can accumulate heat energy and fully utilize solar energy and reach balance. An embodiment is provided along with graphics.
