Abstract
The utility model relates to a vacuum film-coating internally-reflecting solar tube, which is a device used for collecting solar energy to heat water. The solar tube is mainly composed of an inner tube and an outer tube. Both ends of the inner tube are respectively communicated directly with the outside, and both ends of the outer tube are sealed and are welded into a whole with the inner tube. The outer wall of the inner tube is provided with a heat absorbing layer, and the inner wall of the outer tube is provided with a light reflecting layer. The solar energy directly irradiated on the inner tube is absorbed by the inner tube, and the solar energy direct irradiated on the inner wall of the outer pipe is also reflected to the inner tube and is absorbed by the inner tube. So the utility model effectively enlarges the heating area and raises the utilization rate of solar energy.
Description
The utility model is a kind of device that is used to collect the heat energy feedwater heating of the sun, belongs to the technical field of solar heater.
Present various solar water heater has varied, and its critical component is a solar pipe. this solar pipe is collected the height of solar energy efficient, directly have influence on the result of use of solar water heater, therefore the improvement to solar pipe is the improved key of whole solar water heater.Be that the solar water heater of new generation of representative is a kind of product of the most extensive employing at present with the solar pipe of Chinese Tsing-Hua University invention, but the major defect of this product is tens solar pipes to be installed in use and the external reflectance plate just can be received effect preferably, this must make the cost of whole solar water heater increase substantially, in addition, in use, water in the solar pipe is deposited in the inside for a long time, can not be with its emptying, therefore can cause foreign material precipitation and water quality to degenerate, be unfavorable for drinking.
Goal of the invention of the present utility model provides a kind of thermal efficiency height, reflective surface does not stay sedimentary vacuum coating reflection type solar pipe in need not cleaning, managing.
Vacuum coating reflection type solar pipe of the present utility model is made up of interior pipe and outer tube two parts, two of interior pipe is with outside straight-through, two of outer tube is sealed and is welded into an integral body with interior pipe, and the outer wall of interior pipe is provided with heat-sink shell, is provided with reflector layer on the inwall of outer tube.In the pipe with the outer tube disalignment, interior pipe the axle core outer tube diameter 1/3rd to 1/2nd between.The reflector layer of outer tube wall is located at the Lower Half of outer tube wall, and promptly the upper semi-circle of outer tube is a clear glass, and lower half circle is a reflecting surface.During work, direct heating will be internally managed in the sunshine direct projection part of face on inner pipe, and solar light irradiation is in the part of the reflector layer of outer tube, the following and side of pipe in reflector layer reflexes to sunshine, and internally pipe heats.
Advantage of the present utility model is:
Since in this solar pipe the interior pipe of thermal-arrest part not only can collect solar energy from top direct projection to interior pipe upper semi-circle, can also collect the solar energy of coming, so solar energy utilization rate is higher by the outer tube reflective layer reflects, firing rate is fast.
2. because reflector layer is located at the inwall of outer tube, therefore reflector layer can be protected cleaning forever, be in best reflective state always and, also saved the required reflector of solar water heater in the past simultaneously, the production cost of whole solar water heater is further reduced without the labor cleaning.
3. owing to interior pipe is the straight-through straight tube in two, the water that is added into can flow out from the other end from an inflow of pipe, therefore can not produce the phenomenon that hydropexis precipitates with foreign material in pipe, helps drinking.
Fig. 1 is a structural representation of the present utility model.Pipe 1, outer tube 2, reflector layer 3 in wherein having.
Embodiment of the present utility model is as follows:
Getting an endwall respectively thick is 2 millimeters interior pipe (1) and outer tube (2), and the diameter of interior pipe is 30 millimeters, and the diameter of outer tube is 75 millimeters, and the length of interior pipe is 1400 millimeters, and the length of outer tube is 1300 millimeters.At first in the vacuum aluminum-coated blackout of the outer surface of interior pipe as heat-sink shell, at the bright aluminium of inwall lower half circle vacuum light-plated of outer tube as reflector layer (3), then interior pipe is put into outer tube, 50 millimeters of outer tube edges are stretched out at two of interior pipe respectively, and the axis of interior pipe is positioned at the side that outer tube is coated with reflector layer.And be positioned at 1/3rd places of outer tube diameter, and the air between outer tube and the interior pipe is taken out after interior pipe and outer tube are welded into an integral body, form vacuum tube, so just made vacuum coating reflection type solar pipe of the present utility model.
