A high-efficiency solar water heater

Abstract

The invention relates to the technical field of water heaters, in particular to a high-performance solar water heater which comprises a first pulling mechanism, a cable body, a second pulling mechanism, a support mechanism, a liquid adding mechanism, a mixing mechanism, a spraying mechanism and an air drying mechanism. According to the high-performance solar water heater provided by the invention,dust on an outer wall of each heating pipe can be removed simultaneously through a dedusting mechanism, so that the blockage on an outer wall of each heating pipe is reduced, the heat absorption performance of each heating pipe is higher, and a heating effect is improved; water scales on inner walls of the heating pipes can be scraped and flushed out through water, so that heat energy of sunlightreceived by the heating pipes can be effectively conducted into water, the heating effect is further improved, and the high-performance solar water heater is safe, simple and convenient to operate; when a user does not use the high-performance solar water heater for a long time, protection plates can cover on the heating pipes, so that the heating pipes are protected and are prevented from collecting dust; and the heating pipes can rise in summer, so that the heat absorption capacity of the heating pipes is reduced, the heating pipes are prevented from being located at high-temperature high-pressure state for a long time, and the service life of the heating pipes is prolonged.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a high-efficiency solar water heater. Background technique [0002] Solar water heater is a heating device that converts sunlight energy into heat energy, and heats water from low temperature to high temperature to meet the needs of people in life and production. Composition of related spare parts, the conversion of solar energy into heat energy mainly depends on the vacuum heat collecting tube, and the vacuum heat collecting tube uses the principle of hot water floating and cold water sinking to make the water produce microcirculation and obtain the required hot water. [0003] Vacuum tubes are important components for absorbing solar heat sources. After a period of use, a lot of dust will accumulate on the outer walls of the vacuum tubes, and there will be scale on the inner walls. Solar water heater absorbs heat and heats up quickly in sunny days in summer. If no one in...

Problems solved by technology

[0003] Vacuum tubes are important components for absorbing solar heat sources. After a period of use, a lot of dust will accumulate on the outer walls of the vacuum tubes, and there will be scale on the inner walls. Solar water heater absorbs heat and heats up quickly in sunny days in summer. If no one in the house does not use water for a long time, the vacuum tube will be in a state of high temperature and high pressure for a long time, which will cause the vacuum tube to age
