Description
The utility model relates to solar energy heat utilization technical field, particularly a kind of flat plate solar water heater.
At present, flat plate solar water heater with its have that (1) is withstand voltage, the life-span is long, easily form the secondary circuit system, (2) easily with build combine, easily be installed on the roof, the architect easily designs, (3) product materials reproducible utilization rate height, (4) advantages such as effectively daylighting area is big are used widely abroad.And domestic use more be the all-glass vacuum tube water heater.Why is flat plate solar water heater in disfavor in China? reason is:
One, aspect commercial operation, the all-glass vacuum tube water heater is that hot property is far above flat plate solar water heater by factory and businessman's propaganda.Its main reason is a vacuum insulation, and this propaganda very easily is the popular acceptance of China.
In fact, the cover plate of the heat collector of present flat plate solar water heater generally adopts the single-glass cover plate, when the temperature of the thermal-arrest plate (or bar) in the heat collector is higher than outside air temperature, thermal-arrest plate (or bar) just conducts heat to the external world by glass cover-plate, because the heat-insulating property of single-glass cover plate is very poor, goes so a large amount of heat just is lost in the outside air by glass cover-plate.Therefore, the thermal efficiency of heat collector is low, and the liquid outlet temperature is also lower, and the efficient that this just influences solar water heater causes the flat plate solar water heater thermal efficiency not as the all-glass vacuum tube water heater.
A designer person proposes to do with vacuum glass or double glazing the cover plate of heat collector, in order to the heat-insulating property of raising heat collector, thus the thermal efficiency of raising flat plate solar water heater, but actual the use found poor effect.
Two, homemade flat plate solar water heater quality does not pass a test.Show absorber plate meeting oxidation after use a period of time of flat-plate solar collector, cause the solar collecting performance variation.The absorber plate material of the flat plate solar water heater of import is good, thermal efficiency height, and the life-span reaches 15 years, but its price is more much higher than the price of homemade all-glass vacuum tube water heater.
The purpose of this utility model is: at the problem that prior art exists, provide that a kind of cost is low, the vacuum flat-plate heat collector of good heat insulating, thermal efficiency height, long service life.
Another purpose of the present utility model is: provide that a kind of cost is low, the thermal efficiency is high, the evacuated flat panel solar water heater of good heat insulating, long service life.
The utility model is achieved in the following manner: a kind of flat-plate solar collector, form by shell 1, heat-insulation layer 2, thermal-arrest plate 3 and glass cover-plate 4, it is characterized in that: shell 1 and glass cover-plate 4 sealings, and with upper and lower circulation pipe 6,7 sealings of thermal-arrest plate, there is enclosed vacuum chamber 5 heat collector inside.Between the bottom of shell 1 and the glass cover-plate 4 supporter 8 can be arranged.The closing device (9,10,11) of can bleeding on the shell 1.
A kind of flat plate solar water heater comprises water tank 13 and pipeline 6,7, and the heat collector part, and it is characterized in that: heat collector is aforesaid flat-plate solar collector.
The utility model is compared with prior art, and following advantage is arranged: one, because vacuum is pumped in heat collector inside, and thermal-arrest plate 3 is difficult for oxidized in a vacuum, prolong service life greatly.Two, vacuum less demanding (pressure is lower than 30Pa and gets final product), heat-insulation layer 2 can reach insulation effect in a vacuum, and thermal-arrest plate 3 significantly reduces with the heat transmission of shell 1.Three, because vacuum is pumped in heat collector inside, the heat transmission between thermal-arrest plate 3 and the glass cover-plate 4 also reduces.Four, be convenient to safeguard, maintain.After water heater used the several years, when the heat collector internal vacuum descended, the attendant can bleed to heat collector, so that the heat collector internal vacuum reaches requirement once more with portable vacuum pump by the closing device of bleeding (9,10,11).
Accompanying drawing has been described an embodiment of the present utility model.
Fig. 1 is the structural representation of the utility model heat collector.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation of the utility model water heater.
Below in conjunction with accompanying drawing enforcement of the present utility model is further described:
Among Fig. 1,2, shell 1 is to make by cutting, bending, welding with the almag plate, and inside and outside twice full weld is adopted in welding, and is air tight to guarantee the weld seam sealing.Glass cover-plate 4 is tempering ultra-clear glasses, and glass cover-plate 4 covers on shell 1 and with vacuum compound 12 and seals; The upper and lower circulation pipe 6,7 of thermal-arrest plate passes the hole of shell 1 side, and by welding manner up and down circulation pipe 6,7 and shell 1 seal and fix, like this, heat collector inside just forms an airtight cavity.Heat-insulation layer 2 is glass fibre cottons, every play insulation effect between shell 1 and thermal-arrest plate 3.Be welded on the base plate of shell 1 with metal supporter 8, and, between the base plate of glass cover-plate 4 and shell 1, play a supportive role by the hole on thermal-arrest plate 3 and the heat-insulation layer 2.Like this, when the heat collector inner chamber was pumped into vacuum, glass cover-plate 4 can not crushed by atmospheric pressure, and shell 1 can be by the atmospheric pressure compressive strain yet, and heat collector inside can constitute an airtight cavity 5.The diameter in the hole on the thermal-arrest plate 3 is greater than the diameter of supporter 8, and this makes both not contact, to reduce heat loss.When the heat collector size hour, can adopt thick glass cover-plate and shell and without supporter.Stainless steel bolt 10, teflon gasket 11 and the nut 9 that is welded on shell 1 inner surface constitute the closing device of bleeding.
After the assembling of above-mentioned heat collector finishes, the sucker of bleeding of vavuum pump can be enclosed within on the bolt 10, unclamp bolt 10 and bleed, when the pressure of the internal vacuum 5 of heat collector is lower than 0.1Pa, screws bolt 10 and finish pumping process.Can be coated with one deck structure glue again in the junction of bolt 10, pad 11, shell 1, to guarantee to seal and protect the bleeding point of heat collector.
Also heat collector integral body can be placed in the vacuum chamber and vacuumize, seal, and make the heat collector closing device of not bleeding with hot fusion method.
Among Fig. 3, water tank 13 is connected with above-mentioned heat collector by pipeline 6,7.
