Description

The integrated vacuum tube connection of heat-collecting heat-storage collection formula solar water heater

Technical field

The utility model relates to application of solar, specifically a kind of incorporate solar vacuum-tube water heater of heat-collecting heat-storage that does not have water tank.

Background technology

Solar water heater mainly contains flat heat collecting formula and vacuum tube heat collecting type two big classes at present, in the last few years because the improving constantly of all-glass vacuum thermal-collecting tube manufacturing technology level, with the obvious advantage than flat plate collector usefulness, the direct insertion Solar Heater Market share of all-glass vacuum tube constantly enlarges.But than flat-plate collector, the electron tubes type heat collector also has obvious inferior position, that is exactly a unit usefulness manufacturing cost height, the occupation of land space is big, the installation limitation is very big, owing to can only be installed on the more flat roof, not only insulation, the antiseepage function to the roof causes to a certain degree destruction, and for the resident of urban skyscraper, can't use simply, moreover because specification, moulding, color are disorderly and unsystematic, have a strong impact on the overall aesthetic of urban architecture, thereby also suffered many cities prohibiting in some zones.For this reason, some manufacturers have developed so-called separated type solar water heater, promptly adopting heat part and storage tank separated into two parts, connect use with pipeline, being convenient to the urban skyscraper resident installs at balcony or other sunny slopes, also be convenient to install and use with the villa resident family on roof, slope, though this separated type solar water heater has solved the circumscribed problem of installing, it is not how many progressive and raisings aspect manufacturing cost, photo-thermal conversion efficiency and other practicality.In addition, this two classes solar vacuum-tube water heater accumulates sediment easily because the water pipeline design is unreasonable in the pipe, then reduce thermal-arrest usefulness for a long time significantly, and hot water can not directly in time utilize in the pipe simultaneously, also can cause thermal waste greatly.Under the winter extreme weather situation, stifled bad pipe phenomenon appears freezing easily.

Summary of the invention

In order to solve the shortcoming and deficiency that present solar vacuum-tube water heater exists, the purpose of this utility model provides the incorporate vacuum tube connection of the heat-collecting heat-storage collection formula solar water heater of the no water tank that a kind of cost is lower, structure is more reasonable, serviceability is better.

This purpose realizes by following technical proposal: the vacuum tube of this no water tank connection collection formula all-weather solar-energy water-heater device mainly comprises framework, be installed in the connection collection formula ventilating water pipe of the with closure of several the big caliber vacuum heat collection pipes with the same direction opening of spacing discharging in the framework, corresponding connection with thermal-collecting tube, be positioned at the electric auxiliary heating device of thermal-collecting tube bottom.It is characterized in that the inner and outer pipes diameter dimension of the vacuum heat collection pipe of big caliber should be complementary with desired water temperature.The general requirement under the good situation about everyday using of illumination in summer, water temperature is no more than 90 ℃ (to avoid fouling), under the good situation of illumination in winter, water temperature is not less than 60 ℃, then be advisable, vacuumize between the inner and outer pipes, scribble heat-absorbing material on the outer wall of inner tube with diameter of inner pipe =120mm, outer tube diameter =150mm, wall thickness 3-4mm, opening part is beneficial to be incubated and be tightly connected through the necking down processes; Each vacuum heat-collecting tube pitch is 50mm, in order to daylighting.The connection collection formula ventilating water pipe of with closure can adopt high temperature resistant, high-intensity food grade plastic injection molded, also can select for use stainless steel material to make.Its each lid is tightly connected with the corresponding thermal-arrest mouth of pipe, and water inlet pipe passes lid one at the bottom of the thermal-collecting tube.Establishing a delivery port in the lid cavity links to each other with next water inlet pipe.Be provided with the auxiliary heating water tank of electricity in the heat-insulation layer of framework bottom, two ends are connected with the vacuum heat collection pipe inlet tube and outlet tube on top respectively by the composite aluminium plastic pipe, form a closed-loop path; Be provided with a check valve before the vacuum heat collection pipe water inlet, be provided with the excessive valve of air inlet resistance before the check valve; Thermal-collecting tube water outlet place is provided with an exhaust resistance valve, so that go up the emptying of lower pipeline.

The running that this utility model does not have water tank vacuum tube connection collection formula solar water heater is described below: open indoor water supply valve and outlet valve, cold water injects each thermal-collecting tube in parallel through unidirectional water intaking valve, air in tube is overflowed through delivery port exhaust resistance valve and indoor shower nozzle, represent that when the shower nozzle water outlet water fills with, close water supply valve door, outlet pipeline emptying automatically this moment.Each thermal-collecting tube absorbs solar energy, and water temperature raises gradually in the pipe, and the gas that produces in the temperature-rise period is overflowed by the exhaust resistance valve.When water temperature reaches instructions for use, open water supply valve, hot water in each thermal-collecting tube is subjected to the pressure of cold water to promote to flow from front to back successively, special circuit design, the proportion of cold water is greater than the proportion of hot water in addition, the heat exchange amount of cold water and hot water is very little, and hot water can be used to greatest extent, and instant-heating.As continuous rainy weather in winter, or extremely frigid zones northeastward, stifled for avoiding the upper and lower conduit road to freeze, need upper and lower water lines emptying, the utility model design then is very easy to reach this point.Behind the last water, as long as open tap on the watering pipeline, the valve that overflows of the air inlet resistance before the unidirectional water intaking valve is opened by siphonage automatically, and the water in the watering pipeline gets final product emptying.Open out sprinkler head, valve can enter air because the exhaust of delivery port resistance is overflow, and the water in the downcomer also is easy to emptying.A function of auxiliary electric heater unit is, meets the weak or rainy weather of solar irradiation when causing water temperature not reach instructions for use, starts electric auxiliary heating device, can reach the requirement that all-weather is used; Another function is that under extremely frigid zones extreme climate situation (as continuous many days unglazed photographs, environment temperature was lower than-20 ℃), water freezing damage thermal-collecting tube in the thermal-collecting tube can be effectively avoided in the auxiliary heating of electricity a little while of startup in good time.

Conclusion is got up, and the utility model has been concentrated flat and the advantage electron tubes type water heater, has overcome both shortcomings.

1. saving cost.Because saved water tank (roof, slope, balcony hang to install and can save support simultaneously), the product of equal capacity is lower than ordinary vacuum tube solar water heater cost.

2. adapt to multiple mounting means.Owing to take flat structure, and advance water outlet by tap water pressure, both can install on higher one-storey house top, top, slope in the position, also can outside the lower balcony in position, hang installation; Module-integrated structure, easy for installation, saving of work and time especially is fit to building energy conservation integrative development requirement.

3. thermal-arrest usefulness is better.Owing to take the integrated vacuum structure of heat-collecting heat-storage, heat loss still less, temperature retention time is longer.

4. instant-heating uses convenient.Because advance by tap water pressure, discharge pressure is big, it is more powerful to spray water.

5. the auxiliary heating of electricity can guarantee round-the-clock use.

6. special circuit design has been got rid of in the thermal-collecting tube possibility of silt sedimentation of suspension in the water, has thoroughly stopped pipeline and freezes stifled phenomenon.
