Abstract
The invention relates to a high-efficiency vacuum tube, comprising an inner tube and an outer tube, wherein a vacuum layer is formed between the inner tube and the outer tube; a heat-absorbing coating is painted on the outer surface of the inner tube; and a reflecting layer is arranged on the inner wall at the lower part of the outer tube. In the invention, the reflecting layer is used for reflecting sunlight to the half lower part of the inner tube of the vacuum tube to increase the heat radiation area of the vacuum tube, so that the heat-absorbing coating of the inner tube is fully utilized, the heat-collecting effect of the vacuum tube is improved and the temperature of water in a water tank of a water heater is quickly raised.
Description
Technical field
The present invention relates to the vacuum tube of solar water heater, specifically a kind of high-efficiency vacuum tube.
Background technology
The vacuum tube of solar water heater is made of interior pipe and outer tube, is vacuum layer between interior pipe and the outer tube, scribbles heat absorbing coating on the outer surface of interior pipe, the interior effective flow duct that is used as water.
When prior solar water heater is used, have only the first half of pipe in the vacuum tube to receive sunshine, its Lower Half is backlight, can't accept sunshine, the maximum heat area of vacuum tube only accounts for 60% of the gross area, and effective area is little, do not work fully, therefore can not make full use of the heat absorbing coating of pipe in the vacuum tube, the luminous energy of sunshine can not get sufficient utilization, and the collecting efficiency of vacuum tube is low.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of and can fully accept sunshine, high-efficiency vacuum tube that collecting efficiency is high.
According to technical scheme of the present invention: a kind of high-efficiency vacuum tube, pipe and outer tube constitute vacuum layer between interior pipe and the outer tube in comprising, scribble heat absorbing coating on the outer surface of interior pipe, and the inwall of described outer tube bottom is provided with reflector layer.
The described pairing central angle of outer tube wall that is provided with reflector layer is 60 °～180 °.
Described reflector layer is a sheet metal.
Described reflector layer is the coat of metal.
Described reflector layer is a reflecting coating.
One end opening of described interior pipe constitutes the mouth of pipe, and other end sealing constitutes the pipe end, manages the circular arc that is shaped as at the end.
Be shaped as circular arc at the bottom of the described outer tube pipe, the center at the bottom of the outer tube pipe is provided with outside projection.
Technique effect of the present invention is: the present invention is provided with reflector layer, reflector layer reflexes to sunshine the Lower Half of pipe in the vacuum tube, increased the heat area of vacuum tube, the heat absorbing coating of pipe is fully used in making, improved the Heat-collecting effect of vacuum tube, made the water in the water-heater water tank heat up faster.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A cutaway view among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
As shown in Figure 1 and Figure 2, the present invention is a kind of high-efficiency vacuum tube, and pipe 5 and outer tube 1 in comprising constitute vacuum layer 3 between interior pipe 5 and the outer tube 1, scribble heat absorbing coating 4 on the outer surface of interior pipe 5.In a pipe end opening of 5 constitute the mouth of pipe, other end sealing constitutes the pipe end, the pipe end be shaped as circular arc.Outer tube 1 links to each other with interior pipe 5 by circular arc with the corresponding end of interior pipe 5 mouths of pipe, and at the bottom of its other end was the circular arc pipe, the center at the 1 pipe end of outer tube was provided with outside projection 6, and this projection 6 is the end sockets after vacuum tube vacuumizes.Certainly, this projection 6 also can be arranged on outer tube other position at the 1 pipe end.The inwall of the present invention's outer tube 1 bottom is provided with reflector layer 2.
The pairing central angle of outer tube 1 inwall that is provided with reflector layer 2 is 60 °～180 °, and best angle is 180 °.
Operation principle of the present invention: the present invention is provided with reflector layer 2 in the lower inner wall of vacuum tube outer tube 1, the sunshine that shines on the reflector layer 2 is reflected in the vacuum tube Lower Half of pipe 5 through reflector layer 2, heat absorbing coating 4 by interior pipe 5 Lower Halves absorbs, the heat absorbing coating 4 of pipe 5 is fully used in making, increased the heat area of vacuum tube, improved the Heat-collecting effect of vacuum tube, made the water in the water-heater water tank heat up faster.
The present invention is simple in structure, can multi-facetedly utilize solar energy, the collecting efficiency height.
