Wall-mounted solar water heater and manufacturing method of solar heat accumulator

Abstract

The invention discloses a wall-mounted solar water heater. The outer surface of an inner glass tank of a glass-panel solar heat accumulator is flat and smooth, many isometric conical projections are uniformly distributed on the front panel of an outer glass casing and the inner surface of a back panel to be used as supporting points, and the inner glass tank is surrounded inside the outer glass casing. A metal heat absorbing film is plated on the front panel of the inner glass tank of the glass-panel solar heat accumulator and the inner surface of the back panel, and the lateral side of the glass-panel solar heat accumulator is provided with a water inlet and a water outlet. After air in the outer glass casing and the inner glass tank is sucked out, the conical projections on the front panel of the outer glass casing and the inner surface of the back panel press on the outer surfaces of the front panel and the back panel of the inner glass tank respectively. The lateral sides of the inner glass tank and the outer glass casing are semi-arc glass plates and no supporting points are located between the inner glass tank and the outer glass casing, so that the inner glass tank has a displacement space. Further, the solar heat accumulator and a water tank can be protected from being damaged by expansion during freezing due to the fact that a safety valve or anti-explosion rubber pipe are mounted on the non-bearing heat accumulator and the water tank.

Description

Technical field: [0001] The invention relates to a manufacturing method of an arm-mounted solar water heater and a solar heat collector. Background technique: [0002] The solar collectors of wall-mounted solar water heaters can be divided into flat solar collectors with copper tubes inside the glass cover, flat solar collectors with all glass and flat solar collectors composed of vacuum glass tubes. Patent ZL2008101283958 "Solar Heat Collector and Manufacturing Method" refers to the glass inner box of the solar heat collector and the glass outer shell of the solar heat collector. These conical protrusions are the supporting points. When the vacuum is drawn between the flat glass inner box and the glass shell, the conical protrusions on the inner surface of the glass shell are pressed against the outer surface of the glass inner box. That is, the principle of using the tapered protrusions used in the flat vacuum glass plate as the supporting point after the vacuuming of the...

AI Technical Summary

Problems solved by technology

The insulation effect of the copper tube type flat solar collector inside the glass cover is poor

One end of the vacuum glass tube of the vacuum glass tube solar collector is closed, and the vacuum glass tubes cannot be used in series, and can only be used as a non-pressurized solar collector
