Wall-mounted type light wave heating double-layer linker solar water heater

Abstract

The invention belongs to the field of a solar water heater and particularly discloses a wall-mounted type light wave heating double-layer linker solar water heater. The wall-mounted type light wave heating double-layer linker solar water heater comprises a bearing type water tank provided with a water inlet and a hot water outlet. The wall-mounted type light wave heating double-layer linker solar water heater is characterized in that: a medium liquid circulating inner coil pipe located inside a water tank is fixed on the water tank through a flange and a flange cover plate; a filament carbon fiber optical wave pipe is arranged in the circulating inner coil pipe; the optical wave pipe is integrally connected with inner and outer enamel optical wave pipe jackets through a ceramic bracket in a sealed manner; and the circulating inner coil pipe is connected with a panel solar collector board through a circulating outlet pipe connected with a medium liquid outlet and a circulating inlet pipe connected with a medium liquid inlet. The wall-mounted type light wave heating double-layer linker solar water heater provided by the invention has the advantages of simple structure, reasonable design, safety in utilization, greenness, environmental friendless, energy conversation and high efficiency, high heating speed, long service life and small occupied space, and is suitable for wide popularization and application.

Description

(1) Technical field [0001] The invention belongs to the field of solar water heaters, in particular to a wall-mounted light-wave heating double-layer bile solar water heater. (2) Background technology [0002] In the prior art, there are two main types of water heaters made directly by solar photothermal conversion. One is the glass vacuum tube heat collection type, which is the inner tube of a double-layer glass tube nested together, and the inner wall of which is deposited with solar photothermal conversion. Heat-collecting film, the inner tube passes water to take away the heat on the heat-collecting film to complete heat exchange, and the interlayer between the inner and outer tubes is evacuated to reduce the heat transfer from the inner tube to the outside. The disadvantage is that the glass tube is fragile and easily damaged; When the inner pipe is not connected to the water, it is easy to dry burn the tube; the heat collection efficiency is relatively low, bec...

Problems solved by technology

[0002] In the prior art, there are two main types of water heaters made directly by solar photothermal conversion. One is the glass vacuum tube heat collection type, which is the inner tube of a double-layer glass tube nested together, and the inner wall of which is deposited with solar photothermal conversion. Heat-collecting film, the inner tube passes water to take away the heat on the heat-collecting film to complete heat exchange, and the interlayer between the inner and outer tubes is evacuated to reduce the heat transfer from the inner tube to the outside. The disadvantage is that the glass tube is fragile and easily damaged; When the inner pipe is not connected to the water, it is easy to dry burn the tube; the heat collection efficiency is relatively low, because the heat collection film in the medium water bath is in direct contact with the heat collection film, the heat collection film is easily polluted, the service life is relatively short, and the shape is not harmonious with the building. It takes up a large installation area; the second is the ordinary metal thin film flat heat collecting type, which sprays or brushes the heat collecting film on the metal film substrate. The heat energy is obtained, and then transferred to the heat exchange water pipe welded on the substrate film through the substrate film, and then the heat is taken away by the water in the water pipe to complete the heat exchange. The disadvantage is that the heat collection efficiency is relatively low, that is, the solar absorption is relatively low, and the infrared The emissivity is high, and the shape is not harmonious with the building, so it will occupy a large installation area
