Abstract
The utility model provides a vacuum tube solar water heater, which greatly reduces water storage capacity inside a vacuum pipe, increases daily hot water quantity of the solar water heater, prolongs service life of the vacuum pipe and can not leak water when the vacuum pipe is broken. The vacuum tube solar water heater comprises a glass vacuum tube and a water tank, a metal pipe with an enclosed end and an opened end extends into an inner pipe of the glass vacuum pipe, thermal conductive media are arranged between the inner wall of the inner pipe of the glass vacuum pipe and the outer wall of the metal pipe, and the opened end of the metal pipe is in sealing connection with a liner of the water tank and communicated with the liner of the water tank.
Description
Technical field
The utility model relates to a kind of solar vacuum-tube water heater.
Background technology
The solar vacuum-tube water heater overwhelming majority all is direct insertion at present, and promptly vacuum tube directly inserts water tank.Because water is arranged in the vacuum tube, on the one hand, the hot water in the vacuum tube can't take out use, causes very big waste.For example, the water amount of the vacuum tube of a φ 58mm*1.8m is 2.6L, and a water heater is joined 20 vacuum tubes, and then the water amount in the pipe is exactly 52L.So Duo hot water can't take out that to use be a very big waste.In addition, because water directly contacts with vacuum tube, when water temperature and vacuum tube temperature differ than greatly the time, vacuum tube breaks easily; When vacuum tube broke, the water in the water tank all spilt, and can cause in a large number and leak.
The utility model content
The purpose of this utility model provides a kind of solar vacuum-tube water heater that can significantly reduce the water amount in the vacuum tube, and it can improve the day available heat water yield of solar water heater, and the long service life of vacuum tube, and is water-tight when vacuum tube breaks.
This solar vacuum-tube water heater comprises glass-vacuum tube, and the metal tube that water tank, an end seal an end opening extend in the interior pipe of glass-vacuum tube, is provided with heat-conducting medium between the outer wall of the inwall of pipe and metal tube in glass-vacuum tube; The openend of metal tube inserts inner water tank by sealing ring, and communicates with inner water tank.
Its operation principle is: glass-vacuum tube changes heat energy into after absorbing solar energy, passes to metal tube (as copper pipe, stainless steel tube, aluminum pipe or other metal tubes) by the inwall of interior pipe through heat-conducting medium, and then the water in the heating metal pipe.Water in the metal tube again with solar water heater water tank in the water circulation, thereby the water in the heating water tank.
As the further improvement to above-mentioned solar vacuum-tube water heater, described heat-conducting medium is heat transmission fin (as aluminum fin) or conduction oil.
As the further improvement to above-mentioned solar vacuum-tube water heater, the volume of described metal tube is 0.02-0.3 a times of glass-vacuum tube volume.
As further improvement to above-mentioned solar vacuum-tube water heater, the glass-vacuum tube mouth of pipe outside tank shell, and and metal tube between be tightly connected.Best, link to each other by the sealing case ring between the glass-vacuum tube mouth of pipe and the metal tube, be tightly connected between while sealing case ring and the tank shell.
The beneficial effects of the utility model: 1, the volume of metal tube be the glass-vacuum tube volume 0.02-0.3 doubly, the water yield in the metal tube seldom, most water all is the utilizable water in water tank, therefore can improve the useful heat that gets of day of solar water heater greatly.2, go up the water pipe explosion.Because during last water, cold water only in metal tube, can directly not contact with glass tube with vacuum, thereby has prolonged the service life of vacuum tube greatly, has improved the reliability of water heater.3, vacuum tube breaks water-tight.This is because water is sealed in the metal tube, does not have water in the vacuum tube.4, can adopt vacuum tube solid matter mode, improve day of unit collector area useful heat, thereby promote the efficiency grade of water heater greatly.
Description of drawings
Fig. 1 is the partial schematic diagram of solar water heater.
The specific embodiment
Referring to the solar water heater (part) of Fig. 1, metal tube 1 extend in the interior pipe of glass-vacuum tube 3.Aluminum fin (heat transmission fin) 2 is arranged between the outer wall of the inwall of interior pipe of glass-vacuum tube 3 and metal tube, and respectively with they tight contacts.The openend of metal tube 1 inserts water tank (being tightly connected by sealing ring 6 formation between the outer wall of metal tube 1 and the inner water tank 7) by sealing ring 6, and communicates with inner water tank 7.The mouth of pipe of glass-vacuum tube 3 is outside tank shell 5, sealing case ring 4 links to each other with tank shell 5 sealings, seal simultaneously between the mouth of pipe and metal tube 1 outer wall that case ring 4 is arranged on glass-vacuum tube 3, make the mouth of pipe of metal tube 1 outer wall and glass-vacuum tube 3 form and be tightly connected.
Glass heat-collecting vacuum tube changes heat energy into after absorbing solar energy, pass to aluminum fin (heat transmission fin) by the inwall of interior pipe, pass to metal tube by heat transmission fin again, and the water in the heating metal pipe, by free convection, hot water in the metal tube floats to water tank, and cold water flows into metal tube by water tank, thus the water in the heating water tank.
