Solar energy water heater

Abstract

The invention relates to solar water heating technology, in particular to a novel solar water heating system. The novel solar water heating system comprises a vacuum tube solar collector, and a hot water storage tank, wherein the vacuum tube solar collector comprises a bracket and a group of euphotic tubes which are fixed on the bracket and provided with vacuum interlayers; one end of each of the euphotic tubes is connected with the hot water storage tank; a flat heat pipe is arranged in a middle cavity of the euphotic tubes; one end of the flat heat pipe is inserted in the hot water storage tank or is connected with the hot water storage tank; and the flat heat pipe is provided with a through hole which is filled with working substances, and two ends of the flat heat pipe are sealed to form a heat pipe structure. In the novel solar water heating system, the flat heat pipe provided with a capillary heat pipe is arranged in the conventional vacuum glass tube, thereby greatly improving the absorption efficiency of solar energy and the heat transmission efficiency; and compared with the conventional solar water heating system, the novel solar water heating system greatly improves the absorption efficiency of the solar energy and the heat transmission efficiency, and has simple structure, low cost and application and promotion values .

Description

technical field [0001] The invention relates to solar water heating technology, in particular to a novel solar water heating system using flat heat pipes. Background technique [0002] At present, the solar water heating system mainly uses vacuum glass tubes to absorb solar energy to provide hot water. It uses the inner cavity of the vacuum glass tubes to communicate with the hot water storage tanks, and uses the water in the vacuum tubes to absorb the energy of sunlight under the irradiation of sunlight to improve water efficiency. temperature, and then use the temperature difference between the vacuum tube and the water in the hot water storage tank, through the natural convection between the cold and hot water, the water in the vacuum tube repeatedly absorbs solar energy and continuously gathers the generated heat into the hot water storage tank, thereby preparing Hot water at a higher temperature is produced for human use. However, the efficiency of heat transfer by nat...
