Method for increasing heat absorption rate of solar water heater

Abstract

The invention relates to the technical field of water heaters, and specifically relates to a method for increasing the heat absorption rate of a solar water heater. The method is realized through thefollowing solar water heater. According to the method, dust on the outer wall of each heating pipe is removed simultaneously through a dusting mechanism, and then blockage for the outer walls of the heating pipes is reduced, so that the higher heat absorption efficiency of the heating pipes is achieved, and the heating effect is improved; water scale on the inner walls of the heating pipes can bescraped off, and washed away through water, so that the heat energy of the sunlight received by the heating pipes can be much effectively conducted into water, and the heating effect is further improved, and the method is safe, simple and convenient to operate; and the heating pipes can be covered with a protection plate to be protected while being not used by a user for a long time, and dust collection is avoided; and the protection plate can be lifted in summer, and the heat absorption amount of the heating pipes is reduced, so that the long-time high-temperature and high-pressure state in the heating pipes is avoided, and the service lives of the heating pipes are prolonged.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a method for improving the heat absorption rate of solar water heaters. 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 ...

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
