[0023] Example: A phase-change thermal storage solar water heater with enhanced heat absorption

[0024] See attached figure 1 And attached figure 2 As shown, a phase-change heat-storage solar water heater with enhanced heat absorption has the same structure as the existing phase-change heat-storage solar water heater without a heat storage tank, and basically has a box body. The box body can be a metal box body, and the front side of the metal box body is light-permeable glass. One side of the metal box is provided with a fixed bracket on which 6 heat absorbing heat storage units 6 and 2 heat absorbing units 3 are fixed. The structure of the heat-absorbing heat-storage unit 6 includes a solar vacuum heat-collecting tube 7 , and a phase-change heat storage material is arranged inside the solar vacuum heat-collecting tube 7 , and a heat exchange tube 4 is arranged inside the phase-change heat storage material. The phase change heat storage material can be directly sealed in...

Abstract

The invention discloses a phase change heat storage solar water heater with enhanced heat absorption capability. The phase change heat storage solar water heater is characterized by comprising a plurality of heat absorption and storage units and at least one heat absorption unit, wherein each heat absorption and storage unit comprises a solar evacuated collector tube in which a phase change heat storage material is arranged, and a heat exchange tube is arranged in the phase change heat storage material; each heat absorption unit comprises a solar evacuated collector tube in which a heat exchange tube is arranged; and the heat exchange tubes of the heat absorption and storage units are communicated with the heat exchange tubes of the heat absorption units to form a passage. According to the phase change heat storage solar water heater, a heat collection area is enlarged by adding the evacuated collector tubes, so that the heat collection capability is improved; a natural circulation mode is used for transferring heat, so that the phase change heat storage solar water heater is simple in structure and low in cost; and the addition of the phase change heat storage material is avoided, so that the cost can be controlled, and meanwhile, the water heater can be prevented from being overweight.

Description

technical field [0001] The invention relates to a phase change heat storage solar water heater with enhanced heat absorption, belonging to the technical field of solar light and heat. 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, my country's energy consumption is mainly fossil energy 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. [0003] 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 co...
