Abstract
The invention relates to a pressure-bearing glass vacuum pipe of a solar water heater, comprising a glass vacuum pipe. The pressure-bearing glass vacuum pipe is characterized by also comprising a metal pipe sleeved in the glass vacuum pipe, wherein the upper end of the metal pipe is upturned to wrap the upper end of the glass vacuum pipe, and the metal pipe is tightly combined with a liner of a water tank through a silicon rubber seal ring; a seal ring is arranged at a joint position of the end heads of the outer walls of the glass vacuum pipe and the metal pipe by considering air tightness; a gap is retained between the metal pipe and the glass vacuum pipe by considering expansion caused by heat and contraction caused by cold; and a coating with the width of 10<-2>-10<-3> mm is plated on the outer wall of the metal pipe by considering the enhancement of the absorption rate of sunlight. The pressure-bearing glass vacuum pipe not only has high heat exchange efficiency, but also can bear the pressure of tap water from an urban water supply pipeline for a long time, and though the glass vacuum pipe is damaged, the tap water can not leak.
Description
Technical field
The invention belongs to the critical piece glass-vacuum tube of the solar water heater in the new energy field, be specifically related to pressure-bearing glass vacuum pipe of solar water heater.
Background technology
Prior solar water heater is equipped with heat collector on circular water tank, hot and cold water upper and lower conduit, hot water outlet, overfall, electric auxiliary heating device.Existing heat collector is made up of glass-vacuum tube, and vacuum tube directly inserts among the water tank, directly is filled with water in the pipe, and solar radiation makes the water heating in the pipe carry out heat exchange with water in the water tank to heat.The solar water heater of this structure, glass-vacuum tube can only bear the pressure that falls into water naturally from water tank, and can not bear the tap water pressure from city supply water pipeline for a long time, have limited the direct pressure-bearing of water tank and vacuum tube.
Above glass-vacuum tube direct contact water uses, its heat exchanger effectiveness is not high, has the problem of using the restriction aspect again, mainly contains: can not bear the tap water pressure from city supply water pipeline for a long time, in addition, in case vacuum tube damages possibility percolating water or water directly all leaks.
Summary of the invention
The object of the invention provides a kind of pressure-bearing glass vacuum pipe of solar water heater, to overcome the technical deficiency more than the existing glass-vacuum tube.
It is not enough and limit the use problem of solar water heater greatly to the present invention is directed to the glass-vacuum tube bearing capacity, has increased in glass-vacuum tube in red copper metal or the stainless steel specially and has overlapped---and metal tube is as being filled with water tube chamber.Because glass tube walls do not contact water, and inside is with metal tube, makes current can not produce directly pressure to glass tube walls, thereby eliminated the destruction of hydraulic pressure to glass tube.
Therefore, the concrete technical scheme of the present invention comprises glass-vacuum tube, it is characterized in that also comprising a metal tube that is enclosed within the glass-vacuum tube, turn up and encase the upper end of glass-vacuum tube in this metal tube upper end, this metal tube is combined closely in inner water tank by silicone rubber O-ring.
Consider sealing, in the junction of the outer wall termination of glass-vacuum tube 6 and metal tube 1 sealing ring 7 is set again.
Consider and expand with heat and contract with cold that leave gap 9 again between metal tube 1 and glass-vacuum tube 6, the scope in this gap is between 0.5mm～1.0mm.
Consider that increasing sunshine absorbs, be coated with coating 8 at metal tube 1 outer wall, thickness is 10
-2～10
-3Mm.
The constriction coefficient of considering metal tube and glass tube is different, leaves the gap again between metal tube and glass-vacuum tube.
The present invention can bear the tap water pressure from city supply water pipeline for a long time, though vacuum tube damage also not can percolating water or water directly all leak.Therefore the present invention further widens the type of service of present only heat pipe-type of pressure-bearing type solar water heater and coiled bearing structure, promptly created a kind of new solar water heater heat exchange version-water pipe water directly and the hydrothermal exchange of water tank, and improved heat exchanger effectiveness.
Description of drawings
Fig. 1, basic structure schematic diagram of the present invention.
Fig. 2, the general structure schematic diagram when the present invention uses.
Wherein: 1 metal tube, 2 silicone rubber O-rings, 3 inner water tanks, 4 polyurethane insulation coatings, 5 tank shells, 6 glass-vacuum tubes, 7 sealing rings, 8 coatings, 9 gaps.
The specific embodiment
As Fig. 1, comprise glass-vacuum tube 6, it is characterized in that also comprising a metal tube 1 that is enclosed within the glass-vacuum tube 6, turn up and encase the upper end of glass-vacuum tube 6 in this metal tube 1 upper end, and this metal tube 1 is combined closely in inner water tank 3 by silicone rubber O-ring 2.
Consider sealing, in the junction of the outer wall termination of glass-vacuum tube 6 and metal tube 1 sealing ring 7 is set again.
Consider and expand with heat and contract with cold that leave gap 9 between metal tube 1 and the glass-vacuum tube 6 again, the scope in gap is between 0.5mm～1.0mm.
Consider the absorptivity of raising to sunshine, be coated with coating 8 at metal tube 1 outer wall, thickness is 10
-2～10
-3Mm.
The material of above-mentioned coating 8 is ferrimanganic Cu oxides or other can increase the material of sunshine absorption efficiency.
Above-mentioned metal tube 1 is that red copper or stainless steel or aluminum are made.
Obviously, the present invention who constructs thus is the heat exchanger effectiveness height not only, and can bear the tap water pressure from city supply water pipeline for a long time, even vacuum tube damages also non-leakage water or water directly all leaks.
