Description
Technical field
The utility model relates to solar energy evacuated Manifold technology, is specifically related to a kind of high energy efficiency vacuum tube.
Background technology
Solar energy is more and more favored in today that the energy is day by day in short supply as a kind of green, the clean energy, and solar water heater also becomes the selection of huge numbers of families because it is easy to use, stable, efficient.
The main heat absorbing element of solar water heater common is at present solar energy heat collection pipe or collecting plate, collecting plate due to self structure be dull and stereotyped, heat loss is very fast.Thermal-collecting tube hot heat absorption rate is higher, and therefore current domestic conventional water heater adopts heat collecting pipe water heater mostly.
Solar energy heat collection pipe is as the vitals of various solar energy heat collection pipe water heater, and its thermal efficiency, heat absorption heat-insulating property will directly affect economy and the high efficiency of Solar use.
Current thermal-collecting tube comprises outer tube and interior pipe, vacuum layer is formed between outer tube and interior pipe, at the skin of interior pipe, evenly heat-conducting layer is set, but owing to arranging without the relevant flow-guiding structure that separates in thermal-collecting tube, thermal-collecting tube after mounting, thermal-collecting tube only has one side can accept the irradiation of sunlight under normal circumstances, and another side could not accept the irradiation of sunlight, on being just mixed with in same thermal-collecting tube like this, under circulate, in formation, the microcirculation that lower circulation is lumped together, thus cause the efficiency comparison of circulation low, namely collecting efficiency is lower, which reduces the utilization rate of thermal-collecting tube to solar energy.
Utility model content
For above-mentioned deficiency, the utility model object is, provides a kind of smart structural design, rationally, by upper and lower circulation separately, can accelerate circulation rate, improve the high energy efficiency vacuum tube of solar energy utilization ratio.
For achieving the above object, the technical scheme provided is:
A kind of high energy efficiency vacuum tube, it comprises vacuum heat collection pipe and shim, this shim is arranged in described vacuum heat collection pipe, the inner chamber first half of this vacuum heat collection pipe is made to form independent loops chamber, the Lower Half of inner chamber is formed and described lower independent loops chamber, the two ends in upper and lower independent loops chamber are connected, and other position separates, and realize by the upper and lower circulation of vacuum heat-collecting tube cavity separately.
Improve as one of the present utility model, described vacuum heat collection pipe comprises outer glass pipe and is arranged on the inner glass tube in this outer glass pipe, forms closed annular seal space between this inner glass tube and described outer glass pipe.Be provided with annular seal space, insulating efficiency is good.
Improve as one of the present utility model, described shim is stainless steel substrates.The curved convex in middle part of this shim.The junction of this shim and described inner glass tube is provided with sealed silicon adhesive tape, plays and makes the watertight effect of shim upper-lower seal.The lateral surface of sealed silicon adhesive tape is protruding, and with the inner surface of adaptive inner glass tube, the inner side of sealing silica gel strip is recessed into formation one screens suitable with described shim, with convenient for assembly, and good sealing effect.
Improve as one of the present utility model, the outer surface of described inner glass tube has heat absorbing coating, effectively can promote heat absorption efficiency.
Improve as one of the present utility model, described vacuum heat collection pipe is built with working medium.This working medium can be water or anti-icing fluid etc.
The beneficial effects of the utility model are: the utility model smart structural design, and rationally, when sunlight, after the working medium be positioned on shim absorbs solar energy, because the volume that is heated becomes large, density diminishes and automatically floats, and produces the power of cocycle; And the working medium be positioned under shim is not because accepting the irradiation of sunlight; temperature is lower produce under himself Action of Gravity Field under the power of circulation, under the acting in conjunction of cocycle power and lower cyclic force, form the Natural Circulation flowed according to certain rules; greatly accelerate circulation rate; make working medium constantly absorb sunlight heat preferably, thus improve heat absorption efficiency, solar energy utilization ratio is high; the utilization of heat energy is maximized; effective economize energy, protection of the environment, is beneficial to energy-conserving and environment-protective.
