Abstract
A bearable solar energy collector tube using solar radiation to heat the water includes a transparent glass tube, which is characterized in that a metal tube is packaged in the glass tube and two end openings thereof are arranged out of the glass tube; the metal tube is provided with some metal slices; the metal slices is attached with selective heat absorption materials; the space of the metal tube and the glass tube is under vacuum condition. The collector tube not only can bear a high pressure, but also can be directly used for circulation type solar water heater without the problem of pipe explosion. The collector tube makes up the insufficient that present commercial bearable solar energy collector tube can not be directly used for circulation type, especially natural circulation type water heater; the circulation type collector is convenient to do integration design with urban and rural constructions, which has bright application prospects.
Description
But the utility model relates to and utilizes the solar energy heat collection pipe of solar radiation with a kind of pressure-bearing of water heating.
What commercially available solar water heater was used at present is very not withstand voltage all-glass vacuum thermal-collecting tube.For making it can bear higher pressure (pressure), manufacturer generally adopts following two kinds of methods:
The one, all-glass vacuum thermal-collecting tube is combined with hot pipe technique, through the heat pipe indirect heat transfer, make water no longer enter all-glass vacuum thermal-collecting tube.
The 2nd, a U-shaped metal catheter is packaged in the all-glass vacuum thermal-collecting tube of an end opening, allow water only just from the U-shaped conduit, pass through.
Yet the former can not be directly used in the circular form water heater; The latter can only be directly used in the forced circulation type water heater, and can not be directly used in Natural Circulation type water heater.Like this, be subjected to certain limitation with regard to the scope of application that makes them.
The purpose of this utility model is exactly in order to remedy the above-mentioned deficiency of prior art, to make it can bear higher pressure, can being directly used in circular form (comprising forced circulation type and Natural Circulation type) water heater again.
Its technical scheme is as follows: be packaged with the metal catheter of a both ends open outside glass tube in a transparent glass tube, attaching on this metal catheter has some sheet metals; On above-mentioned sheet metal, be attached with the selective heat-absorbing material; Space between metal catheter and the glass tube is a vacuum state.
In order more clearly to explain concrete structure of the present utility model, be further described below in conjunction with Figure of description and optimal way thereof.
In this manual, Fig. 1~4 are the schematic diagram of this pressure-bearing type solar energy heat collection pipe.Fig. 1 and Fig. 2 are the schematic diagram of first kind of optimal way of the utility model, and Fig. 1 is a front view, and Fig. 2 is a vertical view; Fig. 3 and Fig. 4 are the schematic diagram of second kind of optimal way of the utility model, and Fig. 1 is a front view, and Fig. 2 is a vertical view.
In the accompanying drawings, [1] is transparent glass tube (all being broken away in top view), and [2] are the metal catheter of both ends open outside glass tube [1], and [3] are that metal catheter [2] is gone up incidental sheet metal.
In Fig. 1 and Fig. 2, as first kind of optimal way of the present utility model, it is two that metal catheter [2] is gone up incidental sheet metal [3], is strip; They are positioned at the both sides of metal catheter [2], the outer wall of the long limit of one side and metal catheter [2] along the pipe axial engagement together, two sheet metals are symmetry axis with metal catheter [2], shape axisymmetricly, thereby formation wing pipe type absorber.
In Fig. 3 and Fig. 4, as second kind of optimal way of the present utility model, metal catheter [2] is gone up incidental sheet metal [3] to be had more than two, is ellipse; Passed by metal catheter [2] respectively in the middle of them, promptly the outer wall of the middle part of sheet metal [3] and metal catheter [2] circumferentially is bonded together along pipe; Sheet metal [3] constitutes certain angle with the axis of metal catheter [2]; Keep certain distance between each sheet metal, thereby constitute sheet string type (the similar fin-tube radiator of structure) absorber.
In above-mentioned member of the present utility model, the effect of transparent glass tube [1] is to see through sunlight; The effect of the absorber that sheet metal [3] (being to be the master) and metal catheter [2] (being for inferior) are formed is that solar radiant energy is converted to heat energy; The effect of metal catheter [2] (main effect) is that the thermal energy conduction that will produce on the absorber is given the water that supplies heating in the metal catheter [2]; The effect of the selective heat-absorbing material that adheres on the sheet metal [3] is to convert more radiant energy to heat energy; And the vacuum state in the space that forms between metal catheter [2] and the glass tube [1] then is in order to be incubated, and and then improves the thermal efficiency of whole thermal-collecting tube.
Undoubtedly, this thermal-collecting tube can bear the higher pressure that metal catheter can bear, and because of its both ends open outside, as long as it is one or some thermal-collecting tubes (or some heat collectors of being made up of this thermal-collecting tube) is in parallel or be cascaded, its both ends open and thermal storage water tank are linked together, and be aided with the correlation technique measure, be to be easy to form the circular form water heater and and then to realize being heated the Natural Circulation of water or forced circulation.In addition, the glass tube of forming this thermal-collecting tube in use can not contact with water, so water is " bombing " phenomenon not occur when (adding water) on to solar water heater.Should be pointed out that especially above-mentioned circular form water heater (split type water heater) is more convenient for combining with urban and rural buildings and carrying out integrated design, thereby application prospect is still quite wide.
Need to prove that at last as first kind of optimal way of the present utility model, it is suitable for thermal-collecting tube and even can be tiltedly put the occasion of (adapting with local latitude) by the heat collector that this thermal-collecting tube constituted.Can only place (such as heat collector is vertically placed along wall) vertically if thermal-collecting tube is not easy to tiltedly put in other words, then can adopt second kind of optimal way, can increase the heated vertical area of thermal-collecting tube like this, absorb more heat.Here, the angle that axis constituted of sheet metal [3] and metal catheter [2] then should be according to the latitude of locality, and takes into account annual illumination and operating position is taken all factors into consideration definite; The quantity and spacing of sheet metal [3] then should be under the condition that above-mentioned angle is determined, according to the length of thermal-collecting tube, does not block mutually with the sensitive surface (being sunny slope) of sheet metal and to be prerequisite.
