The utility model comprises a bracket, a water storage tank and a row of heat-tube type vacuum tubes, wherein, the water storage tank and the vacuum tubes are fixedly supported on the bracket; heat-tube condensing segments of the vacuum tubes are extended into the water storage tank, and heat absorbing plates are arranged in the vacuum tubes. The utility model is characterized in that the utility model also comprises a row of optical collectors which are arranged on the back faces of the vacuum tubes, and the obverse and the reverse of the heat absorbing plates are both provided with selective absorption coats. The utility model can effectively enhance optical collecting efficiency and heat absorbing efficiency, the quantity of the vacuum tubes is decreased, and the cost of the water heater is reduced. The utility model can be widely used for various family occasions and public bathing occasions.
Description
The utility model relates to a kind of solar vacuum-tube water heater.
Therefore existing heat pipe solar energy water-heater does not generally use concentrator, needs more vacuum tube, and the price comparison costliness of vacuum tube, makes the holding at high price of whole solar water heater.
At the problems referred to above, the purpose of this utility model provides and a kind ofly can reduce vacuum tube quantity, thereby reduces the heat pipe solar energy water-heater of water heater cost.
For achieving the above object, the utility model is taked following design: a kind of heat pipe solar energy water-heater, it comprises a support, one storage tank, one heat extraction tubular type vacuum tube, described storage tank and vacuum tube are fixedly supported on the described support, the heat pipe condenser section of described vacuum tube stretches into described storage tank, be provided with absorber plate in the described vacuum tube, it is characterized in that: it also comprises row's concentrator, described concentrator is arranged on the back side of described vacuum tube, and the positive and negative of described absorber plate all have coating for selective absorption.
The shape of each described concentrator can be compound arc surfaced, and it is made up of two relative cambered surfaces,
The cambered surface cross section of described concentrator can be the parabola of a side brachymemma, also can be the involute of circle.
In order to strengthen the endothermic effect of absorber plate, the shape of absorber plate can be a semi-cylindrical shape.
The absorber plate concave surface of described semi-cylindrical shape can upwards be provided with, and also can be provided with downwards.
The shape of described absorber plate also can adopt planar shaped.
The utility model is owing to take above design, it has the following advantages: 1, the utility model is owing to adopt concentrator, and coating for selective absorption all is set in the positive and negative of absorber plate, therefore can assemble solar radiation from different directions, thereby under the situation that reduces vacuum tube quantity, still can reach the identical thermal effect that adds.2, the utility model makes the spotlight effect of concentrator better owing to adopt various compound arc surfaced concentrator.3, of the present utility model owing to adopt semi-cylindrical shape absorber plate, therefore the increase endotherm area relative with concentrator reaches further increase caloric receptivity, reduces the purpose of water heater cost.The utility model can reduce the quantity of vacuum tube effectively, improves optically focused and heat absorption efficiency, and it can be widely used in various families and public bathing occasion.
Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 3 is the absorber plate structural representation
Fig. 4 is another structural representation of absorber plate
Fig. 5 is an absorber plate structural representation again
As shown in Figure 1 and Figure 2, the utility model comprises a support 1, one storage tank 2, one heat extraction tubular type vacuum tubes 3, absorber plate 4 and concentrator 5.Storage tank 2 and vacuum tube 3 are fixedly supported on the support 1, and the heat pipe condenser section 6 of vacuum tube 3 stretches in the storage tank 2, and absorber plate 4 is arranged in the vacuum tube 3, and concentrator 5 is arranged on the back side of vacuum tube 3, and is fixed on the support 1.Have the hot and cold water import and export on the storage tank 2, and be connected to running water pipe and bathing pipe by pipeline.As Fig. 3, Fig. 4, shown in Figure 5, the utility model difference with the prior art: at first being to have adopted concentrator, secondly is the absorber plate 4 that has adopted semi-cylindrical.Concentrator 5 of the present utility model can adopt compound parabolic concentrator, and it is shaped as the paraboloidal compound of two brachymemmas, from the cross section of concentrator 5, is two parabolical connections, and a side line section of junction is by brachymemma.This concentrator 5 shapes have extraordinary reflecting properties, not needing to follow the tracks of under the situation of the sun, can assemble solar radiation from different directions, thereby can still reach the identical thermal effect that adds under the situation that reduces vacuum tube quantity.In addition, absorber plate 4 of the present utility model adopts semi-cylindrical shape, and the positive and negative two sides of absorber plate 4 all is coated with coating for selective absorption.Semi-cylindrical shape absorber plate 4 can concave uprightly be arranged near in the vacuum tube 3 at the back side, also can concave surface be arranged on downwards in the vacuum tube 3 away from the back side.The shape of this absorber plate 4 can increase the endotherm area relative with concentrator 5, reaches further increase caloric receptivity, reduces the purpose of water heater cost.
Above-mentioned two kinds of situations, with absorber plate (as shown in Figure 3) better effects if in first kind of structure some.Certainly the utility model also can be as prior art, adopt 4 (as shown in Figure 5) of planar shaped absorber plate, even like this, owing to adopted compound parabolic concentrator 5, still can reach the purpose that increases caloric receptivity, because all selective absorbed layer in the positive and negative of planar shaped absorber plate 4 at this moment, the back side also has good heat absorption capacity.
