Description

Technical Field

[0001] This invention relates to the field of solar water heating technology, and more specifically, to a solar water heating system. Background Technology

[0002] A solar water heating system is a device that uses sunlight to heat water. It is divided into vacuum tube solar water heaters and flat plate solar water heaters. Vacuum tube solar water heaters account for 95% of the domestic market share. Vacuum tube solar water heaters are composed of collector tubes, water storage tanks, and brackets and other related components. The conversion of solar energy into heat energy mainly relies on vacuum collector tubes. By utilizing the principle that hot water rises and cold water sinks, the water will generate micro-circulation to achieve the desired hot water.

[0003] Existing solar water heating systems generally use fixed heat collection pipes to collect heat in a fixed direction, which is not very efficient in utilizing solar energy. Therefore, in order to improve the overall utilization rate, there is a device that can change its angle according to the changes in sunlight to improve the utilization rate of solar energy. However, adopting the above method greatly increases the overall price and is not very practical. Therefore, it is rarely used in practice. In reality, the use of fixed heat collection pipes in conjunction with solar water heaters is still the main way to utilize solar energy.
