A phase change heat storage solar water heater with a new heat dissipation structure

Abstract

The invention relates to a phase-change heat storage solar water heater with a novel heat dissipation structure. The phase-change heat storage solar water heater comprises a phase-change heat storage solar water heater body (1) and a heat dissipation device. Evaporation media are arranged inside the heat dissipation device, the heat dissipation device is mounted on the upper portion of the phase-change heat storage solar water heater body (1) and comprises an evaporation tube (2) and a condensation tube (4), the condensation tube (4) is arranged on the outside of the phase-change heat storage solar water heater body (1), the evaporation tube (2) is buried in the phase-change heat storage solar water heater body (1) and is in contact with phase-change heat storage materials in a heat transfer manner, the phase-change heat storage materials are arranged in the phase-changed heat storage solar water heater body (1), an outlet end of the evaporation tube (2) is communicated with an inlet end of the condensation tube (4), an outlet end of the condensation tube (4) is communicated with an inlet end of the evaporation tube (2), and the evaporation tube (2) and the condensation tube (4) form a circulation circuit. The phase-change heat storage solar water heater has the advantages that excessively high internal temperatures of the phase-change heat storage solar water heater can be assuredly prevented owing to a self-circulation mode, a heat dissipation effect can be realized without tap water or a power source, and accordingly water sources and electric power can be saved.

Description

[technical field] [0001] The invention relates to the technical field of solar water heaters, in particular to a phase-change heat storage solar water heater with a new heat dissipation structure. [Background technique] [0002] With the rapid development of China's economy and the continuous improvement of people's living standards, the demand for energy is also increasing. At present, energy consumption is mainly fossil fuels such as coal, oil and natural gas. Due to the limited oil reserves in our country, nearly 50% of crude oil is currently imported, and coal is still the main source of fuel and power in our country. The environmental problems caused by coal burning have become a problem that must be taken seriously in our sustainable development strategy. Solar energy is a huge energy source that does not pollute the environment. The solar energy that the earth obtains every second is equivalent to the energy emitted by burning 5 million tons of high-quality coal. ...

Problems solved by technology

T / P valve constant temperature waterproof needs to ensure the smooth flow of phase change heat storage solar water heater and tap water. When the house has not been delivered or is unoccupied for a long time, there is a danger of overheating caused by tap water failure, and a large amount of hot water needs to be discharged when the overheat protection is activated, resulting in waste.

However, if the automatic sunshade method is adopted, it has the disadvantages of complex system, large investment, high failure rate and power consumption.
