Abstract

PURPOSE:To enable to take out a heating medium heated and collected at an upper header from a plurality of outlet ports without causing stagnation of the flow of the heating medium even if a solar heat collector is made long laterally by increasing the width of the collector, by forming the outlet ports at the upper header in side-by-side relationship. CONSTITUTION:Two outlet ports 5 are formed at the central portion of an upper header 2 adjacently to each other in the direction of the width of the header 2, and each of the outlet ports 5 is associated with one inlet port 4 of a corresponding collector panel 10. Here, since a heating medium supplied from the inlet ports 4 is carried through the collector panels 10 and taken out from mating outlet ports 5, the heating medium circulating efficiency can be raised. Further, baffle plate sections 15 are provided for preventing intrusion of the heating medium introduced from descending tubes 6 directly into adjacent longitudinal pipes 1 located near the descending tubes 6, so that the heating medium is introduced uniformly into a plurality of longitudinal pipes 1 by guiding the heating medium toward the central longitudinal pipes 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar heating lid, and more specifically, a solar heating lid, and more specifically, a solar heating lid, and more specifically, a plurality of vertical pipes arranged on the left and right that run in the vertical direction, and a lid that runs in the horizontal direction that communicates with both the upper and lower ends of each vertical pipe. ) A flow path is formed between the vertical pipes and the pipes, and the heat medium heated by solar heat in the protection channel passes through each vertical pipe and is collected into one pipe due to the difference in specific gravity due to temperature. This relates to a circulating type solar heating lid.

Conventionally, in this type of natural circulation type solar heat collector, increasing the heat collection area K has been achieved either by lengthening the top and bottom of the collector as shown in Figure 1, or by increasing the width of the collector as shown in Figure 2. It is normal to widen (B), but if the vertical length is increased, the lid (A) can be placed on top of the machine.
) T-In case of mounting, the vertical length of the roof surface is required to be longer, and! There is a problem that it is difficult to apply it to roofs of ordinary houses with narrow frontage, where the top F length is shorter than the middle of the left and right sides of the root surface. When (b) is widened, the heat medium flowing toward the soil naturally increases due to the specific gravity difference based on the temperature difference in each vertical pipe (1), as shown by the arrow in the figure. There was a problem that a stagnation part (4) was formed in one place in the width direction of the lid, and as a result, the temperature raising efficiency was worse than that of a vertically elongated lid with the same area. .

The present invention has been made in view of the above points, and an object of the present invention is to provide a solar heat collector driven by Dasein.

Hereinafter, F superposition will be explained in detail. The solar heat collector of the present invention is a collector that heats a heat medium contained in an internal flow path by solar heat received on the outer surface, and the flow path includes a plurality of vertical pipes (1) arranged on the left and right and each running in the vertical direction. , upper and lower spatulas (-(! An F sieve tube (-1) is provided, which communicates with From the F end of pipe (II) to F'9 J -
It is formed in the longitudinal direction of tl1, and the E spatula 4- (21 has a plurality of rounded outlet openings (1) arranged on the left and right for taking out the heated heating medium that collects in the hill head (-iti). This is characterized by the fact that the heating medium is an FA tube (
When it flows in at a), it flows into each vertical pipe (1) through the F header (1), rises in the vertical pipe (1) while increasing its temperature due to solar radiation, and exits from the outlet (I) through the soil header (tlk). When there is an outlet (because there are multiple Il)
mm can be taken out without stopping, and the heat medium flowing from the F ring pipe ts+ at the nine baffle plate part is F # f (
The heating medium flows uniformly into each vertical pipe (1)K by preventing it from directly flowing into the vertical pipe (1)K near @l.

Next, the present invention will be explained in more detail using IAp4. First, the collector panel shown in Figures S to 5 will be explained. The collector panel is integrally molded into a single panel of synthetic resin, and a heat medium flow path is formed inside this collector panel DtAK. is the vertical tube (1), the upper spatula 'J - (t
l and F to @j teril+, m of the 4-point F sieve tube (@) of each double-open vertical tube (1), 'F end of the F peak sieve tube -) to the F header (3). A baffle plate portion a@ extending in the longitudinal direction is formed. Each of the above FM pipes (-) is connected at the F end to the -m end of the doheter opening, and the upper end of each F sieve pipe (6) is connected to the panel (-) through which water is supplied from the intake port (4) projecting upward. A heating medium such as ``F'' passes through the collector spring L (10
The heat medium, whose specific gravity has been reduced by being heated by the solar heat received on the outer surface of the collector panel (1), passes through the vertical tube (1) and is collected in one upper spatula (11 K). The above baffle plate part a→ is approximately 1/4 the length of the F spatula 1- Tl+, and the heat medium flowing from the downcomer pipe (-) directly flows into the vertical pipe near the downcomer pipe (-). [To prevent the heat medium from flowing into the vertical pipes (1), and to spread the heat medium evenly to the central vertical pipe fi+, the heat medium flows uniformly into each vertical pipe (1).Upward two-f! l K is the collector spring V (two outlet sides are provided that protrude above the field, and it is tilted upwards).
(The heated 9 heating medium that collects at tl is supplied from the panel from the intake port (4)
). Each intake (4) and each outlet (6)
is connected to the tank (river) installed on one side of the collector panel (to), and is connected to the tank (river) and the collector panel (to
), the heating medium circulates due to the difference in specific gravity caused by the temperature difference, and the high temperature heating medium is collected in the tank (IlJ).

In this case, the two outlet ports (-) are formed near the center IIIK*a in the width direction of E and Sodder (ri) to show nine rows, and each one outlet +I+ is connected to the collector panel. (One intake (4) on the 101- side corresponds to K, and the heat medium supplied from each intake (4) advances inside the collector panel as shown by the arrow in Fig. 3, and Outlet (
−). As shown in Fig. 4, this collector spring L (11) is connected to the tank (■) installed above the collector panel (to) through the intake port (4) and outlet side, respectively, and the collector panel tU is , as shown in Figure 5, nine boxes + 13 whose surfaces are covered with a111 board O!1
1 and placed on the heat insulating material α4. In the embodiment shown in FIG. 6, the upper spatula 4-+! Formed at the center in the width direction of 9-1, the upper edge (7) with the upper edge of 11 facing upward is formed at the center of the width direction of 9-1.
)K Therefore, the heating medium flowing in the upper header 1-(ilK$ will smoothly proceed to the corresponding outlet (Ii), and factors that inhibit the circulation of the heating medium, such as air pockets, will occur within the upper header area. In the implementation shown in FIG.
The upper edge of the upper spatula 4-t is formed at both widthwise ends of the 1+ at a position corresponding to the upper end of each F sieve tube (6), and the upper edge of the upper spatula 4-t is directed from the widthwise center toward each outlet (6). The hill is shown with an upsloping edge ()), which increases the circulation efficiency as in the previous embodiment. In addition, since each outlet (fl) and the intake (4) are arranged at both ends of the panel in the width direction, when connecting this collector panel to the Tashik (11), as shown in Figure 41111, In addition, the connecting point (1) is located within the range 11 that can be easily reached by the worker (G), making construction easier. Note that ts+ in the figure is a drain port that projects downward from the lower spatula J-(3+ to the collector panel), and is normally closed. This is a comparative example for explanation.In other words, as shown in Fig. 9, if there is no baffle plate (1@), the flow toward the vertical pipe (1) near the sieve wall as shown by the arrow. The weight of circulation in the part (2) indicated by the strong diagonal line is significant compared to other parts (short bus).As a result, the contribution rate of circulation in the central part other than the part α) indicated by the diagonal line is small. However, if the baffle plate section (11) is provided, the water can be guided to approximately the center S as shown in the arrow in the AT diagram, and the short The bus becomes more powerful and the efficiency of the collector as a whole is significantly improved.

As described above, the present invention is a round shape in which a plurality of outlet openings are formed side by side on the left and right in a five-sided shape.In order to increase the heat collection area of the collector, the width of the collector is increased and the whole is formed into an oblong shape. Even if the heated heating medium collects in the vines at the top, it can be taken out from each outlet without allowing it to accumulate in the vines, and this prevents the heated heating medium from accumulating in the vines. Circulation can be performed smoothly and the temperature raising efficiency of the collector can be increased, and when installed on the roof of an ordinary house with a narrow frontage, that is, the hF length of the roof surface is short, a significant increase in heat collection efficiency can be expected. It has the advantage of providing a horizontally elongated collector, and in addition, the rounded baffle plate portions on both left and right ends that prevent the heat medium from directly being introduced from the downcomer pipe into the vertical pipe are located at the longitudinal end of the header from the lower end of the downcomer pipe. Because it is formed in the direction,
There is an advantage that the heating medium also reaches the vertical pipes in the center, and in summer, the heating medium can be uniformly circulated through each vertical pipe, further improving the heat collection effect.
