Abstract
The invention relates to the technical fields of solar hot water engineering and heat supply engineering, particularly to a double-layer vacuum tube solar collector. Existing glass vacuum tube solar collectors are of a single-layer structure and all comprise reflectors and accordingly lead to the problems of being low in collecting efficiency, prone to being turned over in strong winds to result in accidents and high in manufacturing cost. According to the double-layer vacuum tube solar collector, a layer of vacuum collecting tubes are mounted under upper-layer vacuum collecting tubes, and the upper-layer vacuum collecting tubes and the lower-layer vacuum collecting tubes are distributed in a staggered mode; every lower-layer vacuum collecting tube is arranged in the gap between the corresponding upper-layer vacuum collecting tubes; a water collecting tank is a cuboid header, the surface of the water collecting tank, which is connected with the vacuum collecting tubes, is provided with two rows of connecting holes, and square tubes and a support are fixed through bolts; the support and the vacuum collecting tubes are mounted in parallel or vertically on both sides of the water collecting tank. The double-layer vacuum tube solar collector improves the collecting efficiency by more than 40%, saves the reflectors, avoids wind catching, enhances safety and reduces the manufacturing cost.
Description
Technical field
The present invention relates to solar heating engineering and heat supply heating field of engineering technology, specifically a kind of double layer vacuum tube solar thermal collector.
Background technology
Current glass vacuum tube solar heating element is occupied an leading position in China's solar thermal collector market.Simple glass vacuum tube solar heating element basic characteristics are: only have one deck glass vacuum tube solar energy energy thermal-collecting tube; Its standard design is all provided with reflecting plate.Its structure diagram as shown in Figure 1.
The subject matter that simple glass vacuum tube solar heating element exists is:
1, reflecting plate can only reflect small part direct sunlight, and blocks diffusing of back side direct light and ground (or roof of storied building) and surrounding objects, therefore causes its collecting efficiency lower;
2, the installation of reflecting plate makes heat collector go for a drive phenomenon multiplication, after heat collector bracket structure year is aging for a long time, easily throws and cause security incident under high wind weather condition;
3, cost is higher, and cost performance is lower.
Summary of the invention
The object of this invention is to provide a kind of double layer vacuum tube solar thermal collector, to overcome the defect of prior art.
Technical scheme of the present invention is as follows: comprise on header tank and one deck vacuum heat collection pipe is housed, the other end of vacuum heat collection pipe is fixed in the pore in square tube, plastic components buffering conduit saddle is housed between vacuum heat collection pipe and the pore of square tube, sealing ring is equipped with in the junction of header tank and vacuum heat collection pipe, is bolted (conventional art) between square tube and support; Also be equipped with one deck vacuum heat collection pipe in the below of upper strata vacuum heat collection pipe, levels thermal-collecting tube is staggered, and vacuum heat collection pipe often props up between the vacuum heat collection pipe ligament of upper strata in lower floor; Header tank is square header, the plane of connection vacuum heat collection pipe has two row's connecting holes, is bolted between square tube and support; Support or vertical mounting arrangements parallel with vacuum heat collection pipe is in header tank both sides.
Further, the often row parallel hole spacing L of described header tank connection vacuum tube is 0.5 to 2.5 times of vacuum heat collection pipe caliber D, vertical hole pitch H is 0.8 to 2.5 times of vacuum heat collection pipe caliber D.
The invention has the advantages that: double layer vacuum tube heat collector increases considerably heating surface area when not increasing floor space, heat collector collecting efficiency more than 40% can be improved; Eliminate reflecting plate, greatly reduce windage, avoid phenomenon of going for a drive, security is improved; Reduce equipment manufacturing cost, improve product cost.
