Abstract

The utility model relates to a general circulation no-scale full automatic heat collecting pipe solar water heater, which comprises a water tank, heat collecting pipes, a reflecting plate and a bracket, wherein, an inner pipe of the heat collecting pipe is a two end straight type tube, both ends of which are processed into waviness; both ends of the inner pipe and both ends of an outer pipe are sealed and combined on the positions of end ports; vacuum is formed in an interlayer; a water storage tank and a water inlet tank are arranged above and under the bracket; a plurality of heat collecting pipes are arranged above the reflecting plate; both ends of each of the heat collecting pipes are inserted in the water storage tank and the water inlet tank through a sealing ring. The utility model which can reduce the possibility of scale formation and generate favorable heating effect can be used automatically without the requirement of pressing water repeatedly. The general circulation no-scale full automatic heat collecting pipe solar water heater has the advantages of long service life, and convenient installation, use, and maintenance.

Description

Systemic circulation does not have the full-automatic heat-collecting tube solar water heater of incrustation scale

The utility model relates to a kind of water heater, mainly is that a kind of systemic circulation does not have the full-automatic heat-collecting tube solar water heater of incrustation scale.

At present, all adopt the single little internal-circulation type mode of heating of multitube among the existing natural loop solar water heater, thermal-collecting tube 8 ' all adopt one closed and be positioned in the bottom bracket 12 ' hole for round end, insert in the storage tank 1 ' by sealing ring the other end, water in the thermal-collecting tube 8 ' reaches the purpose of heating with the cold water convection current of storage tank 1 ' behind the solar radiation heat temperature raising, because being, water heater tilts to place, thermal-collecting tube 8 ' round end enclosure portion is in the water heater bottom, the deficiency of its structure is: 1) because water is difficult to circulation therein, use through long-term, foreign material in the water are deposited on the thermal-collecting tube bottom gradually and can't discharge, reduce the thermal-collecting tube capacity, reduced the Convective Heating effect; And collector tube inner wall easily scales, and incrustation scale gathers and thickens and cause its heat transmission function to weaken.2) because inlet opening 7 ' and apopore 11 ' all are located in the storage tank 1 ', can't realize automatic use, hot water uses up and is pressed into cold water again, and long use consuming time is inconvenient, and it is relatively poor to add thermal effect.

The utility model is in order to overcome above-mentioned deficiency, and a kind of water flowing in the thermal-collecting tube pipe of quickening is provided, and reduces the formation of incrustation scale as far as possible, and can intake automatically, and adding the preferable systemic circulation of thermal effect does not have the full-automatic heat-collecting tube solar water heater of incrustation scale.

The purpose of this utility model is achieved through the following technical solutions.This systemic circulation does not have the full-automatic heat-collecting tube solar water heater of incrustation scale, comprises water tank, thermal-collecting tube, reflecting plate and support, and the interior pipe of thermal-collecting tube is two through types, and its two are processed into corrugatedly, and two of interior pipe and outer tubes are vacuum at the port involution in the interlayer; The above and below of support is respectively equipped with storage tank and inlet water tank, and several thermal-collecting tubes are located at the top of reflecting plate, and its two are inserted in storage tank and the inlet water tank by sealing ring respectively.

The purpose of this utility model can also be further perfect by the following technical programs.Be provided with heat-insulation layer in described storage tank and the inlet water tank, the bottom of inlet water tank is provided with sewage draining exit.The apopore of storage tank is the threeway apopore, and its lower end picks out water pipe, and last termination exceeds the bleeder pipe of storage tank.

The utility model advantage is: 1) owing to adopted two through type thermal-collecting tubes, be provided with two water tanks of storage tank and inlet water tank, can quicken water flowing in thermal-collecting tube, reduce the possibility that incrustation scale forms, and can produce fuel factor preferably, the needs that pipe expands with heat and contract with cold in corrugated can the adaptation that interior Guan Ertou is processed into.2) need not the repetition setting-out, can use long service life automatically; Install, use and keep in repair all easier.

Engaging embodiment below is further described the utility model.This systemic circulation does not have the full-automatic heat-collecting tube solar water heater of incrustation scale, comprise water tank, thermal-collecting tube 8, reflecting plate 5 and support 4, the interior pipe of thermal-collecting tube 8 is two through types, and its two are processed into corrugated, in pipe and two of outer tubes at the port involution, be vacuum in the interlayer; The above and below of support 4 is respectively equipped with storage tank 1 and inlet water tank 9, is provided with heat-insulation layer 2 in it, and the bottom of inlet water tank 9 is provided with sewage draining exit 10, but the periodical blowdown cleaning keeps clean.Thermal-collecting tube 8 is located at the top of reflecting plate 5, and its two are inserted in storage tank 1 and the inlet water tank 9 corresponding holes by sealing ring 3 respectively, storage tank 1, inlet water tank 9, reflecting plate 5 and thermal-collecting tube are assembled into one.The apopore of storage tank 1 is a threeway apopore 7, and its lower end picks out water pipe, and last termination exceeds the bleeder pipe 6 of about 1 one meters of storage tanks.Storage tank 1, inlet water tank 9 realized the systemic circulation convection current by through type thermal-collecting tube 8, increased the discharge in the pipe, and water temperature raises in sunshine thermal-collecting tube 8, and the interior rate of circulating flow of pipe is big more, thereby tube wall just is difficult for scaliness.During use: water heater is placed towards south by west, after the installation water heater is filled with water and (close V2, open V1 and indoor hot water valve, until the hot water valve water outlet, showing that hot water filled with water) water heater promptly had hot water available through 4-8 hour sunshine, put cold water in the outlet pipe as long as the user opens V1 and indoor hot water valve, just there is hot water to flow out for using, close V1 and indoor hot water valve gets final product with finishing, to need not the repetition setting-out, can reach the purpose of automatic use.Cross low or cut off the water as hydraulic pressure, water heater still can use, as long as open V2, the hot water of storage tank 1 is back to indoor hot water valve for using through inlet opening 11, with after again water heater is filled with water and gets final product.
