Solar water heater with through-type dual-opening vacuum tubes

Abstract

The invention relates to a solar water heater with through-type dual-opening vacuum tubes. The solar water heater is composed of the through-type dual-opening vacuum tubes, tube end plugs, a plug outward moving resistant assembly, a filler, and a support, a heat insulation water tank, a communicating pipe, a control device and a spraying and dedusting device which are matched with the solar water heater. A low-temperature cold water inlet is installed on the lower portion of the tube plug arranged at the lower end of the vacuum tube, a hot water outlet is installed on the sunny slope of the tube plug arranged at the upper end of the vacuum pipe, and the tube plugs can achieve permeability resistance and sealing after the compression of fastening screws. The ends of the vacuum tubes are pressure, permeability and displacement resistant, the water heater is heated gradually in a pipelined mode, heat exchanging is greatly facilitated, the working process can achieve intelligent self-control and full control, the energy efficiency is high, a particularly aperture area can be enlarged, and the solar water heater can be widely applied to solar central heating for residential buildings.

Description

technical field [0001] The invention belongs to the technical field of solar water heater manufacture. Background technique [0002] The hot water outlet of the single-open vacuum tube of the current solar water heater is also the inlet of cold water. The cold water and hot water are mixed. The temperature at both ends of the inner tube is high and the temperature difference is small. Let it cool down, resulting in a lot of waste, and dust accumulated outside the tube for many days, seriously affecting lighting; The installation operation is so idle, and the effective daylighting time is greatly reduced; in large-area solar heat collection projects, the vacuum tubes are arranged horizontally, and their energy efficiency is even worse. The measures of pressure resistance and seepage resistance are not in place, so it is difficult to be practical. Contents of the invention [0003] The present invention aims at above-mentioned defect, and the object is to provide a kind of...
