Novel pressure-bearing type solar water heater

Abstract

The invention relates to the technical field of solar energy, and discloses a novel pressure-bearing type solar water heater. The novel pressure-bearing type solar water heater comprises a supportingbase, a water tank shell is fixedly connected to the top end of the supporting base, an inner container is fixedly connected with an inner cavity of the water tank shell in a sleeved manner, a vacuumheat collecting pipe is fixedly connected to the bottom of the supporting base, and one end of the vacuum heat collecting pipe penetrates through the water tank shell and the inner container. According to the novel pressure-bearing type solar water heater, through a designed heat preservation spring and a heat preservation piston, when tap water stops supplying water to a heat exchange pipe, the heat preservation piston can rebound and block the connecting position of the heat exchange pipe and a water-inlet pipe and the connecting position of the heat exchange pipe and a water-outlet pipe, heat exchange between hot water in the heat exchange pipe and cold water in the water-inlet pipe and the water-outlet pipe is avoided, the heat preservation effect of the water heater is enhanced, the water-outlet pipe loses supply of the subsequent water source, water in the water-outlet pipe can be preferably used in daily water, residents can directly obtain hot water when using the water heaternext time, and the waste of the water resource caused by water drainage during showering of the residents is avoided.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a novel pressurized solar water heater. Background technique [0002] For the demand of environmental protection, more and more families begin to use solar water heaters. The existing solar water heaters are divided into two types: non-pressure bearing type and pressure bearing type. It needs to be placed on a relatively high place such as the roof, and the height difference is used to provide pressure so that hot water can pass into the household, but this still has the disadvantage of insufficient water pressure. [0003] The pressurized solar water heater mainly uses heat collecting tubes to heat the cold water in the water storage tank, and then uses hot water to exchange heat with the heat exchange tubes in the water storage tank to heat the cold water in the heat exchange tubes. The pipe is connected to the water supply pipe network, so it can provide appropriate wate...
