The span of the mounting plane angle α of inclined-plane of the present utility model reflector and vacuum heat collection pipe is 110 °～125 °.Curved surface concentrator of the present utility model is the curved surface that is connect by circular arc plane kiss, and the span of circular arc plan radius R is 110～150 millimeters, and the length direction on each circular arc plane is provided with a vacuum heat collection pipe.The span of the axis of the utility model vacuum heat collection pipe and curved surface concentrator circular arc camber vertical distance h is 33～48 millimeters.
Circular arc plane of the utility model curved surface concentrator is identical with the value of the circular arc plan radius R on an adjacent circular arc plane and the rotation axle base is identical.The value of the axis of a vacuum heat collection pipe of the utility model and curved surface concentrator circular arc plane vertical distance h, identical with the value of the axis of an adjacent vacuum heat collection pipe and curved surface concentrator circular arc plane vertical distance h.
The utility model is compared with existing solar energy vacuum tube water heater, the hot water produced in the water tank and in the vacuum heat collection pipe can be exhausted, improved the daily output hot water amount effectively, prevented that northern severe cold areas vacuum heat collection pipe in winter is damaged, adopted the curved surface concentrator, the sunshine of radiation between vacuum heat collection pipe gathered vacuum heat collection pipe, adopted the inclined-plane reflector simultaneously, the sunshine of incident on the inclined-plane reflector can be reflexed on vacuum heat collection pipe and the curved surface concentrator, the thermal efficiency of water heater improves about 15%, has improved and has produced the hot water amount winter daily.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is the B-B profile of Fig. 1.
Below in conjunction with drawings and Examples the utility model is further described.
In Fig. 1,2,3, the length direction that supports 8-3 in support 8 backs is processed with row's pin-and-hole, bearing diagonal 8-1 supports 8-3 with the back and connects by pin 8-2, change bearing diagonal 8-1 and back and support the coupled position of 8-3, can adjust the angle of inclination on solar water heater and ground, make the utility model in different areas, Various Seasonal produces the highest thermal efficiency.
On the top of support 8 water tank 1 is installed, be used to store water, water tank 1 profile of present embodiment is the pentagonal prism body, overflow pipe 2 is installed the upper side of water tank 1 and water tank 1 links, the bottom is equipped with siphon house steward 3 and links with water tank 1, and when adding water, water flows into from siphon house steward 3, flow in the water tank 1, water is filled it up with the back and is flowed out from overflow pipe 2, and when the user used hot water, water flowed out from siphon house steward 3.Because siphon house steward 3 of the present utility model is installed in the extreme lower position of water tank 1 bottom, the user can exhaust the hot water in the water tank 1.
In the bottom of support 8 curved surface concentrator 5 is installed, curved surface concentrator 5 is to be pressed into metallic plate polishing backlash.The curved surface concentrator 5 of present embodiment be by distance of center circle equate, radius R is that 110 millimeters circular arc plane kiss connects and constitutes, the quantity on circular arc plane according to the daily output hot water amount what and determine that the curved surface concentrator of present embodiment 5 adopts 12 circular arc planes to kiss and connects formation.The tailstock support 9 that is fixed on the support 8 is installed in the lower end of curved surface concentrator 5,12 tailstocks 10 are installed in the tailstock support 9, in each circular arc plane of curved surface concentrator 5, place a vacuum heat collection pipe 6, the oral area of vacuum heat collection pipe 6 inserts that water tank 1 links with water tank 1, afterbody inserts in the tailstock 10 in the tailstock support 9, between the afterbody of vacuum heat collection pipe 6 and tailstock 10, be placed with pad 11, in case vacuum heat collection pipe 6 is damaged.After vacuum heat collection pipe 6 was installed, the vertical distance h on the axis of vacuum heat collection pipe 6 and curved surface concentrator 5 circular arc planes was 33 millimeters.Vacuum heat collection pipe 6 absorbs solar radiation luminous energy, and transform light energy is become heat energy, and the water in the vacuum heat collection pipe 6 is heated, and hot water constantly flows in the water tank 1 and stores, and the cold water in the water tank 1 constantly flows in the vacuum heat collection pipe 6, and heating circulates.A siphon arm 7 is installed in every vacuum heat collection pipe 6, and the lower end of siphon arm 7 is placed on the afterbody, upper end of vacuum heat collection pipe 6 and the siphon house steward 3 in the water tank 1 links.After the hot water in user's water tank 1 uses up, hot water in the vacuum heat collection pipe 6 flows into siphon house steward 3 through siphon arm 7, flow out from siphon house steward 3 then, water in water tank 1 and the vacuum heat collection pipe 6 can be exhausted, prevent that the water freezing in the northern area vacuum heat collection pipe in winter 6 from expanding vacuum heat collection pipe 6 damages, increased hot water effluent's amount simultaneously.
