Abstract
The utility model discloses a solar thermal collector, which comprises thermal collection pipes and reflecting plates, wherein the thermal collection pipes are arranged in parallel; the reflecting plates are arranged at one sides of the thermal collection pipes; the reflecting plates are right-angle trough plates; the cross sections of the reflecting plates are right angled isosceles triangle grooves; the apex angles of the reflecting plates are right angles; the apex angles face downwards; notches formed by two right-angle sides face upwards; the width of the notches is equal 3 times to 3.5 times the diameters of the thermal collection pipes; the thermal collection pipes are arranged on symmetric center lines of the right-angle trough plates; the upper edges of the thermal collection pipes are parallel and level with the notches; and both side edges of the right-angle trough plates are connected with each other. In the utility model, the whole right-angle trough plates are used as the reflecting plates of the solar thermal collector so that the solar thermal collector is convenient to install, can absorb more solar radiation energy and has higher solar use ratio.
Description
[technical field]
The utility model relates to a kind of solar thermal collector.
[background technology]
The heat collector of present solar water heater, used reflecting plate mostly is flat since flat reflecting plate can not be effectively with sunlight reflected to thermal-collecting tube, make solar energy utilization ratio not high, need the vacuum heat collection pipe of a greater number.
Chinese patent application numbers 200920187327 has been announced a kind of " solar collecting device ", it is characterized in that in the middle of two thermal-collecting tubes, installing the inverted V-shaped reflecting plate, its weak point is that each inverted V-shaped reflecting plate does not connect mutually, every reflecting plate is contained on the support separately, also need during installation itself and thermal-collecting tube distance and angle are adjusted, more loaded down with trivial details.
[summary of the invention]
The technical problems to be solved in the utility model provides a kind of easy for installation, the solar thermal collector that solar energy utilization ratio is high.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is that a kind of solar thermal collector comprises thermal-collecting tube and reflecting plate, the thermal-collecting tube placement that is parallel to each other, reflecting plate places thermal-collecting tube one side, and reflecting plate is the right angle trough plate, and its cross section is the isosceles right triangle groove, drift angle is the right angle, drift angle down, two right-angle sides constitute notch up, width of rebate equal 3 times to 3.5 times of thermal-collecting tube diameter; Described thermal-collecting tube places on the symmetrical center line of right angle trough plate, and the upper edge of thermal-collecting tube is concordant with notch; The dual-side of described right angle trough plate interconnects.
As preferably, the bottom centre of described right angle trough plate has strip through-hole along its length.
The beneficial effects of the utility model are that use right angle trough plate can absorb the solar irradiation energy better as the reflecting plate of solar energy heat collection pipe, has higher solar energy utilization rate and easy for installation.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model solar thermal collector embodiment.
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure, 1-thermal-collecting tube, 2-right angle trough plate, 3-strip through-hole, L-width of rebate, Φ-thermal-collecting tube diameter.
[specific embodiment]
Fig. 1 is a kind of solar thermal collector, comprise thermal-collecting tube 1 and reflecting plate, thermal-collecting tube 1 placement that is parallel to each other, reflecting plate places thermal-collecting tube one side, reflecting plate is a right angle trough plate 2, its cross section is the isosceles right triangle groove, drift angle is the right angle, drift angle down, two right-angle sides constitute notch up, width of rebate L equals 3 times of thermal-collecting tube 1 diameter of phi, two right-angle sides of several right angle trough plates 2 have been interconnected to constitute a monoblock right angle flute profile reflecting plate, its connected mode can be used entire plate compression moulding, perhaps connects or welding with bolt.Thermal-collecting tube 1 places on the symmetrical center line of right angle trough plate 2, and the upper edge of thermal-collecting tube 1 is concordant with notch.The quantity of thermal-collecting tube 1 is identical with right angle trough plate 2 quantity.
As shown in Figure 2, have strip through-hole 3, one along the length direction of groove in the bottom centre of right angle trough plate 2, in order to reduce windage, the 2nd, can allow rain drop erosion take away the rubbish that accumulates in the right angle trough plate, avoid influencing reflecting effect.
During installation, thermal-collecting tube 1 is placed in the groove of right angle flute profile reflecting plate top of monoblock, with the right angle flute profile reflecting plate tiltably-mounted of thermal-collecting tube 1 and monoblock on support, over against the sunlight of incident in the south.Because the groove width L of right angle trough plate 2 equals 3 times of the thermal-collecting tube diameter of phi, like this except the sunlight that directly is incident upon the thermal-collecting tube surface, be mapped to sunlight on the right angle trough plate 2 and also almost all reflex on the thermal-collecting tube 1 and be absorbed, equaled to absorb 3 times to the sunlight of thermal-collecting tube diameter.
Claims (2)
1. solar thermal collector, comprise thermal-collecting tube and reflecting plate, the placement that is parallel to each other of described thermal-collecting tube, reflecting plate places thermal-collecting tube one side, it is characterized in that, described reflecting plate is the right angle trough plate, its cross section is the isosceles right triangle groove, and drift angle is the right angle, and drift angle down, two right-angle sides constitute notch up, width of rebate equal 3 times to 3.5 times of thermal-collecting tube diameter; Described thermal-collecting tube places on the symmetrical center line of right angle trough plate, and the upper edge of thermal-collecting tube is concordant with notch; The dual-side of described right angle trough plate interconnects.
2. solar thermal collector according to claim 1 is characterized in that, the bottom centre of described right angle trough plate has strip through-hole along its length.
