Abstract
The utility model relates to a light focusing device used for a solar vacuum heat collecting tube. The utility model is provided with a light reflecting board which is composed of a base board and a light reflecting surface at the surface of the base board. The utility model is characterized in that the shape of the light reflecting surface is a column with paraboloids. When the utility model is used, the vacuum tube is arranged on the position of a focal line; therefore, heat collecting effect can be enhanced, the quantity of the vacuum tubes used for unit daylighting area is reduced, and the manufacturing cost of the vacuum tube solar water heater is reduced.
Description
The utility model belongs to the solar thermal collector technical field.
The heat collector of at present general solar water heater mainly is made up of parts such as many vacuum heat collection pipes, flat reflector and supports.Because flat reflector do not have light-focusing function, the quantity that the heat-collecting capacity that improve solar energy heat collector mainly increases vacuum tube on the unit's of leaning against daylighting area realizes, thereby makes its complex structure, and cost is higher, has limited applying of solar water heater.
The purpose of this utility model is that a kind of beam condensing unit that is used for solar vacuum heat-collecting pipe will be provided, thereby improves the heat-collecting capacity of single solar vacuum heat-collecting pipe, reduces the manufacturing cost of solar water heater heat-collecting device.
The technical solution of the utility model is to have the reflector that the reflective surface by substrate and substrate surface constitutes, and its design feature is that reflector is that xsect is the parabolic post of parabolic shape.
The reflector of this device can be had the mirror face stainless steel plate of reflective surface by the concave surface of parabolic post to be made.On the surface of reflective surface, can scribble diaphragm.
The substrate of this device reflector also can be made by glass, and by the vacuum aluminum-coated reflective surface that is shaped on, the back spraying of reflective surface scribbles layer of aluminum film protective paint, scribbles layer protecting film above the aluminium film protective paint layer on the convex surface of the parabolic post of substrate.
The substrate of this device reflector also can be made by glass-reinforced plastic material, is pasted with one deck vacuum aluminium-plated paper and forms reflective surface on the concave surface of the parabolic post of substrate, is coated with layer protecting film on the surface of reflective surface.
The utility model has the advantages that,, when sunray shines on the reflective surface of reflector, can reflect that to converge to the straight line that parallels with parabolic post be on its focal line according to parabolical focusing principle.If settle solar vacuum heat-collecting pipe to such an extent that overlap with this focal line, the sunlight that then shines on the whole reflective surface just can reflex on the vacuum tube, because the daylighting area of reflective surface is the several times of vacuum heat collection pipe daylighting area, so the heat that adopts this device to be absorbed on the unit vacuum tube can be than not adopting much higher times of this device, thereby can improve the Heat-collecting effect of solar vacuum heat-collecting pipe greatly, reduce the unit daylighting area and use the quantity of vacuum tube, make the structure of solar water heater simpler, cost is lower, is convenient to it and applies.
Below in conjunction with drawings and Examples the utility model is further described.

Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the A portion enlarged drawing among Fig. 2;
Fig. 4 is the A portion enlarged drawing of its another embodiment;
Fig. 5 is the vertical view of the utility model when being equipped with three vacuum tubes.
Main body of the present utility model is the reflector 1 that is made of substrate 4 and the reflective surface 5 that is made in substrate 4 surfaces, there is the flange 2 that has mounting hole substrate 4 left and right sides, reflector 1 global shape is that xsect is parabolical parabolic post, during use solar vacuum heat-collecting pipe 3 is installed on (see figure 2) on the focal line of parabolic post.Reflector (1) can be by the moulding of mirror face stainless steel plate stamping, and the concave surface that its minute surface is made in parabolic post is as reflective surface (5).If in rugged surroundings, use, can be at the surface of reflective surface (5) spraying one deck unsaturated polyester resin as diaphragm 6 (see figure 3)s.
Another embodiment of the present utility model adopts the glass bending moulding process that glass plate is made parabolic post as substrate 4; adopt vacuum aluminum-coated system mirror method to make the border face as reflective surface 5 at the convex surface of substrate 4; spray layer of aluminum film protective paint 7 earlier at reflective surface 5 back sides, spray one deck unsaturated polyester resin as diaphragm 6 (see figure 4)s on its surface again after drying.
Substrate 4 of the present utility model also can be made moulding by glass-reinforced plastic material; paste vacuum aluminium-plated paper as reflective surface 5 at the concave surface of substrate 4, form diaphragm 6 at the surface of reflective surface 3 spraying one deck unsaturated polyester resin or the formulated coating of alkali silicate silane coupling agent again after bonding agent solidifies.
When this device width during greater than 1 meter, remove to overlap a vacuum tube 3 is installed with focal line, also can be at vacuum tube of each side installation of this vacuum tube, with raising Heat-collecting effect (see figure 5).
