Solar continuous water heating apparatus

Abstract

The invention discloses a continuous solar energy water heating device which comprises a triangular bracket and a solar energy water heater assembly that is arranged on the oblique surface of the triangular bracket, and is characterized in that: the solar energy water heater assembly is formed by a water inlet channel, a water outlet channel and a plurality of levels of water heating and circulating units with the same structure, which are serially connected; a cool water input port is arranged in the water inlet channel that is connected with the water heating and circulating unit of the first level, and a hot water output port is arranged in the water outlet channel that is connected with the water heating and circulating unit of the final level. The continuous solar energy water heating device has the advantages that the device overcomes the defects of low heat efficiency, long water temperature increasing time and less water heating volume which are caused by that the existing vacuum pipe type solar energy water heaters seal the natural circulating water for heating. As the continuous solar energy water heating device produces hot water by open type pressurized tap water circulation and heat exchange, users can select the levels of the water heating and circulating units that form the continuous solar energy water heating device. The continuous solar energy water heating device has the advantages of scientific design, reasonable and simple structure, and large hot water output, and the like. The continuous solar water heating device is a novel solar energy water heating device that is in accordance with energy-saving and environmental protection requirements and is applicable to generalized and popularized use.

Description

technical field [0001] The invention relates to a solar heating device, in particular to a solar continuous water heating device. Background technique [0002] Existing solar water heaters are usually vacuum tube solar water heaters, which mainly consist of a water storage tank, a glass heat collecting tube, and a support. The water storage tank is a cylindrical object with multiple jacks. The water storage tank is composed of two layers of metal materials inside and outside with a body temperature layer in the middle. It is used for water storage; the glass heat collecting tube is like an elongated kettle. The gallbladder is composed of two glass tubes, one large and one small. The outer layer is transparent, and the inner layer is coated with light-selective absorbing coating. The inner and outer tubes are evacuated into a straight space. It is the core of the solar water heater. To maximize the absorption of heat energy after solar radiation; the bracket supports the ent...

Problems solved by technology

Proof of use: When a vacuum tube solar water heater is sunny, it can only produce tens of kilograms to several cubic meters of domestic hot water a day, which can only meet the needs of one to twenty households, but cannot meet the needs of dozens of floors and hundreds of households. Household heating water consumption

Secondly, once the existing vacuum tube solar water heater encounters rainy days for many days, the limited hot water storage cannot meet the needs of users.
