効率で集熱することは困難であった。However, even if it is installed at the same angle with respect to the installation surface, the heat collection efficiency changes depending on the latitude of the installation area, the angle of the installation surface at the installation location, etc. The work had to be installed at an appropriate angle, and the task tended to be cumbersome. Also, the appropriate angle varies depending on the season, and it has been difficult to collect heat with the same efficiency throughout the year.

It was difficult.

In that case, in order to prevent the internal fluid of the heat collector from boiling, it is necessary to cover the entire heat collector with a light-shielding plate or the like, and there has been a problem that the attaching and detaching work is troublesome. In addition, when a protective member such as glass is not separately provided on the upper surface of the casing,
When disturbance such as hail occurs, it is necessary to cover the entire heat collector with a separate protective member to protect the reflective surface of the reflector and the heat collector,
There is also a problem that the attaching and detaching work is troublesome.

A heat collection unit comprising a body and a reflector partially surrounding the heat collector to reflect sunlight to the heat collector;
In one or a plurality of heat collectors, the reflector is supported rotatably around the tubular heat collector.

By rotating the reflection plate to a position where the light is not reflected, the boiling of the internal fluid of the heat collector can be prevented. In addition, even when disturbance occurs when there is no separate protective member, the reflection plate can be rotated to a position that does not reflect sunlight to the heat collector to protect the reflection surface of the reflection plate and the heat collector.

制御すると良い。FIG. 2 is a front view of the heat collecting unit 2 in which a pipe connecting the heat collecting body 3 is omitted, and FIG.
It is the figure seen about the III line. As shown in FIGS. 2 and 3, the reflecting plate 4 of each heat collecting unit 2 is rotatably supported about the heat collecting body 3 (point O in FIG. 2) via a bearing 6. Thus, there is no need to separately provide a rotating shaft, and the number of components is reduced. Adjacent heat collecting units 2 are spaced apart from each other so that the reflection plate 4 can rotate. A pinion gear 7 is fixed to one end of the reflection plate 4 of each heat collection unit 2, and these pinion gears 7 mesh with the rack member 8. The rack member 8 is supported by rollers 11, protrudes outside at the corners of the casing 1, and has a handle 9 at its end. Therefore, the reflecting plate 4 of each heat collecting unit 2 is driven to rotate via the rack member 8 and the pinion gear 7 by driving the handle 9 in the retracting direction. Also,
Instead of or in addition to the handle 9, an output shaft of a motor 10 (imaginary line) as an actuator may mesh with the rack member 8 and be driven by the rack member 8. In that case, the reflector 4 may be rotated by a control device (not shown) according to the latitude, installation angle, season (date), time, etc., of the place where the device is installed, and the reflector 4 may always be controlled in an optimal direction. .

It is formed into a gutter-like shape that forms a central part and reinforced with a plurality of ribs. Here, the compound paraboloid, the cross-section is a shape formed by combining a pair of identical parabolas and an involute curve forming an angle θ,
The light incident from the opening is most efficiently reflected toward the heat collector 3 near the bottom surface (see, for example, US Pat. No. 4,002,499). The projection 4a at the center thereof is ideally preferably in contact with the heat collector 3, but the tip is lowered and slightly spaced (gap) in order to prevent heat dissipation and heat loss due to the contact.

常に安定して集熱することが可能となる。The operation of the heat collecting device will be described below. First, it is assumed that the heat collecting device is installed at an angle of, for example, 30 ° with respect to the installation surface in consideration of the latitude of the installation area, the angle of the installation surface of the installation location, and the like. Then, from the state shown in FIG. 2, as shown in FIG. 5, for example, in a range of ± 30 ° via the rack member 8 and each pinion gear 7 so as to substantially face the sun in consideration of the installation angle, the season, and the like. The reflection plate 4 is rotated and tilted. At this time, if the reflectors 4 are in close contact with each other, they may be shaded by the adjacent reflectors 4 when tilted, so that the amount of light received by the reflectors 4 may not increase and may decrease on the contrary. Due to the slight separation, the amount of light received by each reflector 4 becomes substantially constant regardless of the rotation angle,
It is possible to always stably collect heat.

A position that does not reflect sunlight to the heat collector. This makes it possible to prevent the internal fluid of the heat collector from boiling when heat collection is not required. Further, in the case where the protection and heat retaining member 5 is not provided, the structure is also effective for protection from disturbance.

一層期待できる。In the above configuration, each reflector 4 is rotated by a combination of the pinion gear 7 provided on the reflector 4 and the rack member 8. However, the present invention is not limited to this.
They may be connected by a connection gear, driven by a chain or a belt, or rotated by a combination of link members without using a gear. Further, the actuator is not limited to the rotary motor, and a linear motor, a hydraulic actuator, or the like may be used. Furthermore, in the above configuration, the reflector 4 is processed into a gutter-like shape forming a CPC. However, when a normal reflector, for example, a parabolic surface is used, or when a reflector having a compound paraboloid is used, Since it is more desirable to face the sun as much as possible, the effect of applying the present invention can be further expected.

By rotating the reflector to a position where no reflection occurs, it is possible to prevent boiling of the internal fluid of the heat collector, prevent deterioration of the seal due to an increase in pressure, and improve the durability and reliability of the device. In addition, even when there is no separate protective member, even when disturbance occurs, the reflector can be rotated to a position where the sunlight is not reflected by the heat collector to protect the reflection surface of the reflector and the heat collector.

The angle can control the reflector.
