Description
Technical field
The utility model relates to application of solar, especially a kind of solar water heater.
Background technology
Solar water heater is energy-conservation and obtain more and more widely application with it.Present main product is single-cycle vacuum tubular glass solar collector, patent ZL200620030598.x discloses a kind of circulation switch type solar water heater, its structure is: the storage tank that is provided with heat-insulation layer outward is placed on the support, one group of heat collecting vacuum pipe is obliquely installed the side at storage tank, and the interior pipe upper end of vacuum tube is communicated with storage tank top, top, storage tank side is provided with water inlet pipe mouth, bottom, storage tank side is provided with effluent pipe mouth, the vacuum tube lower end is provided with the following tube connector that is connected with pipe in it, is being provided with the following circulation pipe that is communicated with them between tube connector and the storage tank bottom down.Its principle is to utilize the proportion difference of hot and cold water, produces circulation, but the circulation route of this structure is long, and resistance is bigger, is unfavorable for effective heating.And comparatively heavy, installation inconvenience, insulation are difficult for guaranteeing.
The utility model content
The purpose of this utility model provides a kind of quick hydronic solar water heater of realizing.
For achieving the above object, the utility model adopts following technical scheme: a kind of solar water heater, comprise support, support is provided with upper collecting chamber and next part case, between upper and lower collection case, vertically in a row be tiltedly installed with thermal-collecting tube, thermal-collecting tube all is communicated with upper and lower collection case, is communicated with heat-insulated pipe between upper and lower collection case.
Described heat-insulated pipe vertically is obliquely installed between thermal-collecting tube row, and the port height of heat-insulated pipe is lower than the port height of thermal-collecting tube in upper collecting chamber, and the port height of heat-insulated pipe also is higher than thermal-collecting tube port height in the next part case.
Described thermal-collecting tube and heat-insulated pipe are the glass tube with vacuum of both ends open, are coated with heat absorption coating in the thermal-collecting tube.
Be coated with adiabatic coating in the described heat-insulated pipe.
Be provided with water inlet, delivery port, sewage draining exit and be arranged on the exhaust outlet at upper collecting chamber top on upper collecting chamber, also be provided with delivery port and sewage draining exit on the next part case, described two delivery ports are in parallel and finally be communicated with outlet pipe.
Upper collecting chamber and next part case are equipped with heat-insulation layer outward.
The beneficial effects of the utility model are: because thermal-collecting tube and heat-insulated pipe are provided with simultaneously, can produce heat, cold two kinds of different current respectively in thermal-collecting tube and heat-insulated pipe, water temperature height then density is little, and water temperature is low, and then density is big, it is poor to produce severe thus, water is circulated between thermal-collecting tube and heat-insulated pipe, and this kind circulation is main circulation of the present utility model, that is: the hot water in the thermal-collecting tube rises, current in the heat-insulated pipe descend, resistance greatly reduces, and water velocity increases, and the efficiency of heating surface is improved.Heat-insulated pipe adopts glass tube with vacuum, then by vacuum insulation, prevents to freeze in the pipe in winter.Certainly, also can in glass tube with vacuum, increase adiabatic coating, make insulation effect desirable more according to meteorological condition.Heat-insulated pipe also vertically is obliquely installed between thermal-collecting tube row, is convenient to circulation, also heat-insulated pipe can be arranged at thermal-collecting tube row's centre, and then the heat-insulated pipe bilateral symmetry is provided with, and makes the current uniform distribution; In the utility model, also produced a kind of auxiliary circulation in addition: promptly higher owing to the thermal-collecting tube position in upper and lower collection case, the heat-insulated pipe position is lower, the hot water from top to down flows into heat-insulated pipe in upper collecting chamber, and in the next part case cold water from bottom to top enter thermal-collecting tube, form hot water or cold water's directed flow.Behind the water heater long-play, can add certain density cleaning mixture or thimerosal carries out scale removal and sterilization to water heater by filling pipe end, waste liquid can be discharged from sewage draining exit, and the thermal efficiency of water heater and water quality are recovered after washing.Upper and lower collection case all is provided with sewage draining exit, is convenient to blowdown more.The upper collecting chamber top is provided with exhaust outlet can get rid of the gas in upper and lower collection case and thermal-collecting tube and the heat-insulated pipe when water from water inlet, also can not form negative pressure in the collection case because hot water flows out during use.Delivery port can be arranged on upper collecting chamber and be beneficial to and obtain the higher water outlet of temperature; Be arranged on the next part case and be beneficial to increase and use water capacity, but next part case leaving water temperature is low slightly; Also can upper and lower collection case all set out the mouth of a river and be installed in parallel, this moment, leaving water temperature be moderate, stable and water capacity is also big.Upper collecting chamber and next part case are equipped with heat-insulation layer outward, and water is incubated for a long time.In addition, because the water circulation thermal efficiency improves, can reduce the thermal-collecting tube radical, thereby dwindle the water heater width, help in limited roof area, installing more water heater, moreover owing to increased the next part case, the water heater center of gravity moves down, good stability is suitable for the skyscraper installation that blast is big and the roof area is less, meets the developing direction of solar energy cause.

The specific embodiment
Embodiment 1:
By a kind of solar water heater illustrated in figures 1 and 2, comprise that the bottom is provided with the support 4 of supporting plate 7, support 4 tops are provided with upper collecting chamber 1, supporting plate 7 is provided with next part case 6, upper collecting chamber 1 and the next part case 6 outer heat-insulation layers 2 that are respectively equipped with, 5, last, next part case 1, vertically in a row be tiltedly installed with thermal-collecting tube 3 between 6, also comprise a heat-insulated pipe 8 that vertically is obliquely installed in the middle of thermal-collecting tube 3 pipe rows, thermal-collecting tube 3 and heat-insulated pipe 8 are respectively with last, next part case 1,6 are communicated with, and the port height of the heat-insulated pipe in upper collecting chamber 18 is lower than the port height of the thermal-collecting tube 3 in the upper collecting chamber 1 as far as possible, and the port height of the heat-insulated pipe 8 in next part case 6 also is higher than the thermal-collecting tube 3 port height in the next part case 6 as far as possible.Thermal-collecting tube 3 is glass tube with vacuum with heat-insulated pipe 8, be coated with heat absorption coating in the thermal-collecting tube 3, in heat-insulated pipe 8, add adiabatic coating, on upper collecting chamber 1, also be provided with water inlet 13, delivery port 11, sewage draining exit 9 and be positioned at the exhaust outlet 10 at upper collecting chamber 1 top, also be provided with delivery port 11 and sewage draining exit 9 on the next part case 6.
