Light wave heating balcony wall-hanging solar water heater
(1) technical field
The invention belongs to the solar water heater field, particularly a kind of light wave heating balcony wall-hanging solar water heater.
(2) background technology
In the prior art, directly utilize the water heater of solar energy optical-thermal conversion of productions to mainly contain two major types, the one, the glass-vacuum tube heat collection type; It is the interior pipe of the double-layer glass tube that is nested together; Its inwall deposits solar energy optical-thermal Transform Sets hotting mask, and the heat that interior pipe water flowing is taken away on the thermal-arrest film is accomplished heat exchange, and the interlayer between inner and outer pipes is evacuated; The outside heat transmission of pipe in reducing, its shortcoming be because of glass tube frangible and fragile; Interior pipe is prone to the dry combustion method bombing when not leading to water; Collecting efficiency is relatively low, makes thermal-arrest film pollution because medium water-bath thermal-arrest film directly contacts, and service life is shorter relatively, and profile and building construction owe harmony, take bigger erection space; The 2nd, common metal film flat heat collecting type is that the thermal-arrest rete is perhaps brushed in spraying on the metallic film substrate, and solar radiation is behind the thermal-arrest rete; The photo-thermal conversion makes the thermal-arrest rete obtain heat energy, passes to the heat exchange water pipe that welds on the substrate membrane through substrate membrane again, takes away heat through the water in the water pipe again; Accomplish heat exchange; Its shortcoming is that collecting efficiency is relatively low, and promptly solar absorptance is lower, and infrared emittance is higher; And profile and building construction owe harmony, take bigger erection space.More than the solar water heater of two major types all be the roof that is placed on building, perhaps on the vacant lot on building next door.
