Solar water heater with double heat collection systems

Abstract

The invention discloses a solar water heater with double heat collection systems. The solar water heater comprises a supporting device. A water tank is fixedly installed on the top of the supporting device. A water inlet pipe is fixedly installed on the top of the water tank, and a water outlet pipe is fixedly installed on the bottom of the water tank. A charge pipe is fixedly installed on one side of the water inlet pipe. An inner glass column is arranged in the water tank. Heat insulation plates are arranged at the two ends of the inner glass column respectively, and a heat absorption film layer covers the inner glass column. According to the solar water heater with the double heat collection systems, by arranging the inner glass column in the water tank and arranging the heat insulation plates and the heat absorption film layer cooperatively, the heat insulation effect of the inner glass column is improved; by arranging inner pipes and outer pipes, the heat collection effect of vacuum heat collection pipes is improved; by arranging protrusions and reflection layers, the area, absorbing the solar energy, of the vacuum heat collection pipes is enlarged, and the heat collection efficiency is improved; by arranging a water conveying pipe and a hose, sediments of the vacuum heat collection pipes are cleared, and the service life of the vacuum heat collection pipes is prolonged.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar water heater with double heat collection systems. Background technique [0002] A solar water heater is a device that converts sunlight energy into heat energy, and heats water from low temperature to high temperature to meet the needs of hot water in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structure, and vacuum tube solar water heaters are the main ones, accounting for 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on vacuum heat collecting tubes. To achieve the required hot water, but the water tanks of solar water heaters currently on the market have poor thermal insulation ef...

Problems solved by technology

Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on vacuum heat collecting tubes. To achieve the required hot water, but the water tanks of solar water heaters currently on the market have poor thermal insulation effects, and the heat collection efficiency of the heat collecting tubes is very low, and the heat collecting tubes will remain with a lot of sediment as they are used, making the use of the heat collecting tubes difficult. Reduced lifespan and poor use effect
