Abstract

The utility model relates to an extension inner tube type wholly glass vacuum tube (vacuum tube for short), which is designed to perfect a solar water heater. The vacuum tube mainly consists of an extension inner tube and a covering glass tube and the top end of the extension tube is higher than the covering glass tube. When the wholly glass vacuum tube is inserted into a water tank to form a water heater, because the extension inner tube is longer than the covering glass tube, the top end of the extension inner tube can be arranged at a relatively high position in the water tank; when the water heater operates normally, the water at a lower temperature which naturally flows into the vacuum tube is reduced, and thus the scale is greatly reduced; as the extension inner tube can be used for holding more water, the cold water can be prevented from flowing into the vacuum tube to cause explosion; if the wholly glass vacuum tube is broken or worn outside the water tank, only the water in the water tank higher than the tube opening and the water in the vacuum tube can flow out; thus the utility model prevents an excessive amount water in the water tank from flowing out of the broken or worn tube; and further the water heater is ensured to operate normally.

Description

Lengthening Inner tubular type all-glass vacuum tube

Technical field

The utility model relates to the solar water heater technology, is tubular type all-glass vacuum tube in a kind of lengthening specifically.

Background technology

Along with rapid economy development, energy supply and environmental problem become increasingly conspicuous.Because oil product has only a few countries to grasp, and very easily causes dispute, use fossil energy then to cause the discharging of carbon dioxide isothermal chamber gas, make global warming, reduce human lives's condition, destroy the earth ecology balance simultaneously.Solar energy is as new forms of energy, and its material is not limited to, and everybody can equality shares, contaminated air not, but be the energy of cleaning continuous utilization.

In China, solar water heater has become China solar energy most widely used general, industrialized development product the most rapidly in utilizing, and it is subjected to consumers in general's favor with safety economy, energy-conserving and environment-protective, advantage such as the energy is renewable, use is simple.By dealer's unremitting effort for many years, the solar water heater technical development is rapid, and it is leading in the world, with low cost to have had scientific and technological level height, manufacturing technology essence, production scale, feature such as international competitiveness is strong.The primary structure of solar water heater comprises as the vacuum heat collection pipe of heat collecting element with as the parts such as heat storage water tank of heat accumulation element.For improving the solar water heater technology more, the utility model has createed the more optimal vacuum heat collection pipe of performance.

Summary of the invention

The purpose of this utility model just provides tubular type all-glass vacuum tube in a kind of lengthening, and compared with prior art, it has more high-quality characteristics.

The technical solution adopted in the utility model is as follows:

The tubular type all-glass vacuum tube is made up of pipe and cover glass tube in the lengthening in the lengthening, be vacuum interlayer between two pipes, pipe is longer than cover glass tube in the lengthening, and its top is higher than cover glass tube, tube-surface has solar selective absorbing coating in the lengthening, and the pipe bottom is provided with support member and breathing film in the lengthening.

After all-glass vacuum tube inserted water tank and forms water heater, because pipe is longer than cover glass tube in the lengthening, so can make higher relatively position in water tank, water inlet of managing the top in the lengthening, the advantage of this structure was:

Because pipe is longer than cover glass tube in the lengthening, the pipe top is in position higher relatively in the water tank in the lengthening so can make, reduce by the lower water yield of relative temperature that flows into naturally in the vacuum tube in the time of making the water heater operate as normal, fouling is greatly reduced; Pipe can make the pipe internal volume increase in the lengthening, can hold the more water yield, helps to prevent because the blasted pipe phenomenon that cold water produces when entering vacuum tube; If all-glass vacuum tube when breakage water tank outside, then have only the part water yield and the interior water of vacuum tube that are higher than the mouth of pipe in the water tank to run off, the water yield that is lower than the mouth of pipe in the water tank is kept, and has avoided the interior too much hot water of water tank to flow out from the pipe of breakage, thereby has guaranteed that water heater still can operate as normal.

Utilize the solar water heater cleanliness without any pollution that the tubular type all-glass vacuum tube is made in the lengthening, do not consume conventional energy resource, one-time investment can use for a long time, safe ready is in every field such as hotel, field such as restaurant, dwelling house, school, hospital, office, processing aquaculture will be widely used.

The specific embodiment

Embodiment: describe the tubular type all-glass vacuum tube specific embodiment in the lengthening in detail below in conjunction with accompanying drawing 1-3.

The tubular type all-glass vacuum tube is made up of pipe 1 and cover glass tube 4 in the lengthening in the utility model lengthening, be vacuum interlayer 3 between two pipes, manages 1 in the lengthening than cover glass tube 4 length, and its top is higher than cover glass tube 4, and its raised area is cylindrical or be syphon shape.Pipe 1 also can adopt extension pipe and conventional pipe ways of connecting to realize in the lengthening, and can to select the cross section for use be the special pipe of different shape to extension pipe like this.There is solar selective absorbing coating 2 on pipe 1 surface in the lengthening, and the pipe bottom is provided with support member 5 and breathing film 6 in the lengthening.

Claims

1. tubular type all-glass vacuum tube in the lengthening, it is characterized in that it is made up of pipe (1) and cover glass tube (4) in the lengthening, it between two pipes vacuum interlayer (3), pipe (1) is longer than cover glass tube (4) in the lengthening, its top is higher than cover glass tube (4), there is solar selective absorbing coating (2) on pipe (1) surface in the lengthening, and pipe (1) bottom is provided with support member (5) and breathing film (6) in the lengthening.
