Description

A kind of novel flat-plate solar heat pipe collector

Technical field

The utility model relates to the solar heat pipe collector of technical field of solar utilization technique.

Background technology

Utilize solar thermal collector to provide heat energy, use for a long time for water heater.In recent years, various pressure-bearing type solar heat collectors appear again.Solar heat pipe collector adopts the heat pipe superconduction to conduct heat, thermal capacity is little, start soon, do not leak water in the solar energy vacuum tube, but pressure-bearing, anti-empty the solarization, be difficult for booster, fundamentally solved full-glass solar energy collecting vacuum tube and caused the drawback of systemic breakdown, can be used for producing high-temperature-hot-water, boiling water because of fouling causes reduction of heat effect and single tube breakage, and very strong freezing tolerance is arranged, and being very suitable for winter temperature is 0 ℃ to-40 ℃ area.General planar vacuum heat pipe or other forms of solar thermal collector, solar thermal energy is passed to water in the fixed volume water tank, only the water to relative static conditions in the water tank heats, and already heated hot water, if be stored in the water tank not removed always, when treating that the night or the solar heat energy are very faint, then whole system has become heat abstractor, makes the hot water in the water tank become cold water again very soon.In addition, the ceiling temperature of hot water can not be controlled in the water tank.

Summary of the invention

At the deficiency of above-mentioned existing solar thermal collector, the technical problem that the utility model mainly solves is, a kind of novel flat-plate solar heat pipe collector is provided.

The technical solution adopted in the utility model is, a kind of novel flat-plate solar heat pipe collector, comprise water tank and flat-plate heat pipe heat collector, described flat-plate heat pipe heat collector comprises the heat pipe of one group of overcoat glass solar energy collecting vacuum tube, it is characterized in that: also comprise the cycle set thermic devices, it comprises thermal-collecting tube, circulation pipe and circulating pump, described heat pipe is connected with thermal-collecting tube, the thermal-collecting tube loop exit of described thermal-collecting tube one end, be connected with water tank circulation import by circulating pump, other end thermal-collecting tube circulation import is connected with the water tank loop exit, is communicated to water tank.

Novel flat-plate solar heat pipe collector described in the utility model, adopt the cycle set thermic devices that the circulating fluid (water) of containers such as water tank is heated (thermal-arrest), all advantages that not only kept existing flat plate collector, also because the flow circuit of liquid has improved the efficiency of heating surface, can make full use of solar energy and and keep heat energy, can control the ceiling temperature of required hot water, to be fit to different instructions for uses, it is simple in structure, manufacturing, easy to install and use.

The specific embodiment

For the purpose of narration and diagram were simple and clear, clear, some device of the utility model did not give diagram in the accompanying drawings, but did not influence the related personnel that the comprises one skilled in the art understanding to the present utility model content.Below in conjunction with embodiment and accompanying drawing the utility model is further described.

Embodiment 1:

As shown in Figure 1, the panel solar heat pipe heat collector of present embodiment mainly is made up of the thermal-collecting tube 3 and the circulation pipe 4 of flat-plate heat pipe heat collector, water tank 1, circulating pump 2, cycle set thermic devices.The inner chamber of water tank 1 adopts rotational moulding anticorrosion, and shell is provided with heat-insulation layer, and is provided with water tank circulation import 11 and water tank loop exit 12.The some heat pipes 6 overcoat glass solar energy collecting vacuum tubes 5 of flat-plate heat pipe heat collector, be provided with heat transmission fin (not drawing among the figure) between they the two, the release end of heat of heat pipe 6 directly stretches into thermal-collecting tube 3 inner chambers, be connected with thermal-collecting tube 3 liquid sealings, also can adopt soldering or electric welding to connect, thermal-collecting tube 3 shells are provided with heat-insulation layer.The thermal-collecting tube loop exit 32 of thermal-collecting tube 3 one ends (output), be connected with the water tank circulation import 11 of water tank 1 by circulating pump 2, the thermal-collecting tube circulation import 31 of thermal-collecting tube 3 other ends (input) is connected joining water box 1 by circulating line 4 with water tank loop exit 12.The flat-plate heat pipe heat collector absorbs solar thermal energy the water in the thermal-collecting tube 3 is heated, when water reaches 60 ℃ of the ceiling temperatures that set, temperature detect switch (TDS) (not drawing among the figure) is opened circulating pump 2, with the hot water in the thermal-collecting tube 3 from water tank circulation import 11 suction water tanks 1, simultaneously, the relatively low water of original temperature in the water tank 1, from another water tank loop exit 12, return in the thermal-collecting tube 3 by circulation pipe 4 circulations, reduce with water temperature in the additional thermal-collecting tube 3 of recirculated water, temperature detect switch (TDS) then turn-offs water pump 2.In addition, can fixedly add a cover clear glass on glass solar energy collecting vacuum tube 5 protects.

Embodiment 2:

The present embodiment structure is similar substantially to embodiment 1, as Fig. 2, shown in Figure 3, difference is, thermal-collecting tube 3 is fixedly welded with and connects its thermal-arrest sleeve pipe 33 radially, the two becomes one, thermal-arrest sleeve pipe 33 1 ends (upper end) sealing, an end (lower end) opening, described heat pipe (6) inserts from opening part, is connected with its tight cover.Since heat pipe 6 not with thermal-collecting tube 33 in water directly contact, can prevent to produce incrustation scale, also be convenient to maintenance, safeguard.In addition, thermal-collecting tube 3 replenishes the water source of water inlet from circulation import 31, can also be by threeway or triple valve, connect water tank 1 and water supply pipe, provide by water tank 1 and water supply pipe, perhaps separately from water supply pipe, be that thermal-collecting tube circulation import 31 disconnects with water tank 1, directly connect water supply pipe.

Above embodiment example as an illustration, accompanying drawing is only illustrated, is not the qualification that the utility model is done.In addition to the implementation, the utility model can also have the embodiment of other cycle set thermic devices, for example, can adopt magnetic valve that recirculated water and running water are controlled; In the device except water being done the circulation heating, can also be with other liquid of opposing heating that circulates, or the like, this not superfluous one by one stating.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all belong to the protection domain of the utility model requirement.
