Solar heat-collection plate, solar heat collector and solar water heater

Abstract

The invention relates to the technical field of solar water heaters and discloses a solar heat-collection plate which comprises at least a splice plate. The splice plate is provided with at least a pipeline. The pipelines extend longitudinally along the splice plate and are arranged side by side. The transverse ends of the splice plates are sequentially spliced side by side, the longitudinal frontand tail ends of the splice plates are sequentially communicated to form an S-shaped liquid flow channel and a liquid inlet end and a liquid outlet end are respectively formed at both ends of the S-shaped liquid flow channel. The machining technology of the solar heat-collection plate is quite simple and the production efficiency is higher. Besides, the pipeline of the solar heat-collection plateis not formed by huffing, and the pipeline wall is thicker and can bear greater pressure. The invention also discloses a solar heat collector and a solar water heater.

Description

technical field [0001] The invention relates to the technical field of solar water heaters, in particular to a solar heat collecting plate, a solar heat collector and a solar water heater. Background technique [0002] Along with the raising of people's living standard, the application of water heater in daily life is more and more extensive. [0003] Existing water heaters are divided into gas, coal-fired, oil-fired water heaters, and several major categories such as electric water heaters according to energy sources. What the above-mentioned gas, coal-fired, and oil-fired water heaters consume are all non-renewable energy sources, and also cause environmental pollution; meanwhile, as energy prices continue to rise, the above-mentioned gas, coal-fired, and oil-fired water heaters are expensive to use, bringing users a greater economic burden. Because the electricity consumption is large, the price of electricity also has the trend of continuous growth, and there are no sm...

Problems solved by technology

[0012] The pipe in the solar heat collecting plate processed by this solar heat collecting plate processing method is formed by blowing the aluminum plate with high-pressure gas, and the thickness of the aluminum plate will become thinner, so that the pressure that the pipe wall can bear is smaller. If the pressure in the hot plate is too high, the pipe wall may be crushed, causing water leakage

In addition, this method of processing solar heat collectors needs to perform processes such as printing pipeline distribution maps, pressing, and blowing expansion on aluminum plates, and the processing technology is complicated, especially when it is necessary to process solar heat collectors with a large area. The requirements of the process are higher, which limits the area of ​​the solar collector plate, and the solar collector plate with too large area cannot be processed by this method
