Problems solved by technology

The collector has the characteristics of high efficiency, good antifreeze, and is not easy to break; and it can realize dual heat sources of solar energy and air, which solves the shortcomings of traditional solar water heaters that are affected by the weather and the system cannot run around the clock; The heat exchanger is integrated with the tube-belt heat exchanger and fins with high heat exchange efficiency. It can not only use water as the medium, as an ordinary solar water heater collector, but also use refrigerant as the medium (as an evaporator), Composition of solar-air composite heat source heat pump operation

Embodiment Construction

[0025] The pressure-bearing vacuum flat solar collector 18 of the present invention is mainly composed of a glass cover plate 1, an end baffle plate 2, a bottom plate 13, a perfusion fan 3, a side baffle plate 4, a check air valve 6, a bottom insulation layer 12, and a side insulation layer. 14. The heat collecting plate 15, the heat transfer tube 11, the aluminum tube strip 10, and the heat transfer fin 16 are composed. Glass cover plate 1 is made of upper glass cover plate 8, lower glass cover plate 9, bead 7 and sealing strip 5 around. There are several heat pump working fluid passages 17 on the aluminum pipe strip 10 .

[0026] The heat loss of the vacuum flat plate collector is mainly concentrated in the heat transfer to the surrounding air through the vacuum glass cover plate 1 . In order to reduce heat transfer. The main measure in this design is to evacuate between the two glass plates, which reduces the heat loss of the heat collecting plate 15 to the environment. ...

Abstract

The invention provides a pressure type vacuum panel solar thermal collector. A glass cover plate (1) is constituted by an upper glass cover plate (8), a lower glass cover plate (9) and a surrounding sealing strip (5); two opposite end baffle plates (2), two opposite side baffle plates (4), the glass cover plate (1) and a base plate (13) which are arranged at the upper and lower sides of the end baffle plates (2) and the side baffle plates (4) together form a whole; a perfusion fan (3) is arranged on the end baffle plate (2); a non-return air valve (6) is arranged at the inner side of the side baffle plate (4); a bottom insulating layer (12) is arranged on the base plate (13); a side insulating layer (14) is arranged at the inner side of the side baffle plate (4); a heat collecting board (15) is arranged on the bottom insulating layer (12); a heat transferring tube (11) is arranged on the upper surface of the heat collecting board (15); a heating transferring fin (16) is arranged on the lower surface of the heat collecting board (15); an aluminium duct tape (10) is arranged below the heat collecting board (15); and the aluminium duct tape (10) is provided with a plurality of heat pump working medium channels (17).

Description

technical field [0001] The pressurized vacuum flat plate solar collector consists of a double-layer vacuum glass plate as the cover plate, an extruded plastic insulation material as the bottom plate and edge sealing and heat preservation, and an aluminum flat tube belt as the medium flow channel. The invention belongs to the technical field of solar energy application, and in particular relates to the structural design of solar heat collectors and solar heat pump heat collectors / evaporators. Background technique [0002] Solar collectors are the main components of solar heat utilization. [0003] The most widely used in China is the solar collector of glass vacuum tubes. With the intensification of energy problems, high-rise buildings urgently need to use solar collectors to provide domestic hot water or heating in winter, but ordinary glass vacuum tube collectors are not easy to match buildings perfectly. combined. The flat plate collector is more and more popular because...
