A long-life solar water heater

Abstract

The invention provides a solar water heater with a long service life. The solar water heater comprises a heat preservation water tank, a water feeding pipe is welded to a left side plate of the heat preservation water tank, a fixing base is internally provided with heat absorption pipe fixing holes, and the bottoms of the heat absorption pipe fixing holes are filled with buffering protection layers. According to the solar water heater with the long service life, firstly, the junction positions of the heat absorption pipes and the fixing base are internally provided with the buffering protection layers, and for the impact force generated when water suddenly enters into the heat absorption pipes, the protection layers can well protect the heat absorption pipes from being damaged; secondly, the junction positions of the heat absorption pipes and the heat preservation tank are provided with stretchable connection pipes, rotating shafts are welded to the heat absorption pipes, and sliding wheels are welded to the rotating shafts and can move in grooves, so that when the heat absorption pipes are impacted by water, the heat absorption pipes can perform location moving within a certain range, and the cracking phenomenon between the heat absorption pipes and the heat preservation water tank can be avoided.

Description

technical field [0001] The invention belongs to the technical field of solar energy equipment, and in particular relates to a long-life solar water heater. Background technique [0002] A solar water heater is a heating device that converts sunlight energy into heat energy, and heats water from low temperature to high temperature, so as to meet the hot water use 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. Get the hot water you need. [0003] However, existing solar water heaters have some deficiencies during use, and the heat abs...

Problems solved by technology

[0003] However, existing solar water heaters have some deficiencies during use, and the heat absorption tubes will often be damaged. The heat absorption tubes are basically installed in a fixed position, which will cause water in the heat absorption tube When impacting, an impact force is formed on the bottom, which will easily cause damage to the heat absorbing tube
