Abstract
This invention relates to a solar energy vacuum heat-collecting panel water heater, which applies a heat sink plate coated with heat sink layer on the flat thermal tube panel in a vacuum flat heat-collecting box to absorb solar energy radiation heat passing through a transparent cover plate on the vacuum heat-collecting box, in which working fluid in the flat thermal tube is gasified at low temperature and vacuum and its steam is converted in a tiny temperature-difference super-conduction phase to the top of the thermal tube to heat the coiled water heater and flowing current in the coiled tube continuously with the heat-storage steam in the working fluid.
Description
Technical field:
Solar powered water heater of vacuum heat collection flat heat pipes belongs to solar energy and utilizes heat-pipe apparatus.
Background technology:
Solar energy is inexhaustible, nexhaustible clean energy resource, but solar energy density is very low, China's solar water heater from the vexed solarization chamber of the first generation to the flat plate collector of the second generation, entered the third generation all-glass vacuum thermal-collecting tube water heater epoch at present, solar energy utilization rate progressively improves; Country's 863 projects, the hot pipe type vacuum heat collection pipe solar water heater, also put on market, the solar water heater technology is brought up to a new height, but they all are to adopt single glass (heat pipe) vacuum heat collection pipe to combine side by side, in heat collector, accept the radiant heat energy of solar energy, the other end stretches into water tank and emits heat and add hot water, this multitube combined solar water heater arranged side by side, and the manufacturing process complexity, manufacture difficulty is big, cost is high, the market price is high, popularity rate is low.
Summary of the invention:
The objective of the invention is to design a kind of in the built-in direct heat(ing) coil water heater of flat-plate heat pipe intraductal working medium phase transition of vacuum of vacuum plate heat collection case the novel and high-efficiency solar water heater of current.
Technical scheme of the present invention is on the base plate of solar powered water heater of vacuum heat collection flat heat pipes by plate type evacuated heat-collecting box (1) flat-plate heat pipe (2) to be installed and outside storage tank (3) is formed; The insulation material (5) of the casing of the Packed transparent cover plate in vacuum heat-collecting flat rack (1) top (4) and bottom, on the interior lower plate of flat-plate heat pipe (2) electrical auxiliary heater (6) is arranged, internal upper part has coil pipe water heater (7), scribbling the solar radiation thermal absorptivity on the framework around the top panel of flat-plate heat pipe (2) reaches is z=0.96, emissivity is＜0.0866 selective coating (8), the water inlet pipe (9) of coil pipe water heater (7) and outlet pipe (10) pass the tedge of the same storage tank of side top board (3) of flat-plate heat pipe (2) and vacuum heat-collecting flat rack (1) respectively, and down-comer connects forms the natural circulation heating system; The binding post of the electrical auxiliary heater (6) of the interior lower plate in flat-plate heat pipe (2) working medium (11) passes the interior lower plate seal welding of flat-plate heat pipe (2), auxiliary heating when same temperature controller (12) connects as deep cooling, flat-plate heat pipe (2) is installed on vacuum heat-collecting flat rack (1) base plate, behind the sealed transparent cover plate, collection flat heat case (1) is evacuated to get final product.
The present invention compares with prior art has following technique effect:
1, solar powered water heater of vacuum heat collection flat heat pipes is a double-layer vacuum monolith-type heat pipe water heater, it has overcome many independently all-glass vacuum thermal-collecting tube formula and heat-pipe vacuum heat collecting pipe formula water heater manufacturing complexity, cost is high, the problem of be difficult for promoting has also overcome all-glass vacuum thermal-collecting tube formula solar water heater situation of icing quick-fried row in the pipe when tight plug simultaneously.
2, solar powered water heater of vacuum heat collection flat heat pipes adopts endotherm area big, the double-layer vacuum structure of good heat insulation, absorber plate scribbles the selective coating of sunshine high-absorbility, and greenhouse effects are listed as by force, flat-plate heat pipe (2) heat absorption, the vaporization of working medium (11) vacuum and low temperature, it is to be the continuous heated plate heat pipe of storage heater (2) internal upper part coil pipe water heater (7) with working medium (11) boil-off, and it is not subjected to hydraulic pressure, the influence of water quality, thermal efficiency height, low cost of manufacture.
3, flat-plate heat pipe (2) places in the dull and stereotyped casing of vacuum heat-collecting (1), and heat-absorbent surface can not pollute, and has avoided the all-glass vacuum thermal-collecting tube formula to be heated water and has walked in glass tube, causes humic scale problems in the pipe.
4, the same storage tank of solar powered water heater of vacuum heat collection flat heat pipes (3) adopts the divergence type draw bail, is convenient to water heater storage tank (3) cleaning is installed.
Description of drawings:
Fig. 1 is a front view of the invention process.
Fig. 2 looks cutaway view for the right side of the present invention.
Referring to figure (1) figure (2), the invention process mainly contains that vacuum heat-collecting flat rack (1), flat-plate heat pipe (2), storage tank (3), transparent cover plate (4), insulation material (5), auxiliary electrical add device (6), coil pipe water heater (7), choose selecting property coating (8), water inlet pipe (9), outlet pipe (10), working medium (11), temperature controller (12).
The specific embodiment:
When the invention process, electrical auxiliary heater (6) is installed on the lower plate in flat-plate heat pipe (2) in elder generation and internal upper part is installed into coil pipe water heater (7) seal welding that water pipe (9) outlet pipe (10) stretches out heat pipe side top board, strict cleaning treatment, inject working medium (11), be evacuated, after qualified Upon Strict Inspection, around reaching, flat-plate heat pipe (2) upper panel coats selective coating (8) on the framework, then flat-plate heat pipe (2) is fixed on vacuum heat-collecting flat rack (1) the base plate insulation material (5), water inlet pipe (9) and outlet pipe (10) adapter are stretched out vacuum heat-collecting flat rack (1) side, the top board seal welding, sealing installation transparent cover plate (4) is evacuated in vacuum heat-collecting flat rack portion, water inlet pipe (9) that last vacuum heat-collecting flat rack is outer and outlet pipe (10) are with the tedge of external storage tank (3), and down-comer connects.A solar energy double-layer vacuum collection flat heat formula heat pipe water heater.
