Abstract
The invention relates to collectors of solar water heaters, in particular to a flat plate collector capable of being vacuumized. The flat plate collector is composed of a water tank and an outer shell.
Description
Affiliated technical field
The present invention relates to a kind of heat collector of solar water heater, the flat plate collector in especially a kind of solar water heater.
Background technology
At present, known solar thermal collector mostly is glass-vacuum tube heat collector, also has minority flat plate collector simultaneously.Glass-vacuum tube heat collector, because Heat-collecting effect is remarkable, has captured more than 95% market of solar water heater.But also there is its technical deficiency------easily to occur bursting by freezing and bombing, in the intensive city of high-lager building, use very dangerously, therefore the solar energy in city is concentrated in hot water and industrial hot water market, be difficult to base oneself upon.
The advantage of flat plate collector is safe, attractive in appearance, is easy to and building one integrated mass.In recent years by the favor of solar energy industry active development, but its topmost problem is that Heat-collecting effect is nothing like vacuum tube, how flat plate collector also being made to vacuum is the target that in industry, numerous enterprises is pursued, due to its complex structure sealing difficulty, owing to being that slab construction is difficult to bear huge air negative pressure, sealing and intensity are the most scabrous problems again.
Summary of the invention
In order to solve sealing and the strength problem of vacuum panel solar thermal collector, the invention provides a kind of brand-new structure, this structure can not only guarantee that flat plate collector has good sealing property and has the enough intensity of resisting negative pressure.
The present invention solves the technical scheme that its technical problem takes: negative pressure plate solar collector consists of water tank and shell two parts, it is characterized in that water tank consists of cover plate, reinforcement, chassis etc., and the cover plate sensitive surface of water tank has heat absorbing coating; Space up and down in shell can be evacuated, and shell consists of glass cover-plate, shell chassis, reinforcement, protection support lattice etc.; Water tank is less than shell, is arranged on the inside of shell, and with partial points is soldered, connects between shell, must have enough gaps between the two, and the space up and down of enclosure is communicated; All reinforcements and protection support lattice support perfect rigidity between shell chassis, water tank chassis, cistern cover plate and glass cover-plate; In this structure, be also provided with vacuum nozzle, water inlet pipe, steam vent and outlet pipe.
The invention has the beneficial effects as follows: because shell is an integral body, make to need the place of sealing to be simplified to minimum, again because glass cover-plate and the flange above shell are all plane combinations, be easy to sealing after adding fluid sealant, the effect after overtesting is really fine.Again owing to having two-layer reinforcement and one deck protection support lattice that perfect rigidity between shell chassis, water tank chassis, cistern cover plate and glass cover-plate is supported, therefore make overall structure produce enough anti-negative pressure intensity.

Specific embodiments
Negative pressure plate solar collector consists of water tank and shell two parts, it is characterized in that: water tank consists of cistern cover plate 4, reinforcement 2, water tank chassis 14 etc., and the sensitive surface of cistern cover plate 4 has heat absorbing coating 8; The space up and down of enclosure can be evacuated 6, and shell consists of glass cover-plate 5, shell chassis 16, reinforcement 2, protection support lattice 7, fluid sealant 1 etc.; Flange 9 combinations of glass cover-plate 5 and shell, there is fluid sealant 1 centre; Water tank is less than shell, can be arranged on the inside of shell, and with partial points is soldered, connects between shell, must have enough gaps 10 between the two, and the space up and down of enclosure is communicated; All reinforcements 2 and protection support lattice 7 will be rigid support between shell chassis 16, water tank chassis 14, cistern cover plate 4 and glass cover-plate 5 completely.
