Description

[Detailed Description of the Invention] The present invention relates to a heat collecting and dissipating device mainly used for roofs with tile and stick roofs.

In recent years, various devices have been developed that utilize solar heat, which is inexhaustible and clean energy, and one of them is a solar collector for use in roofs with tiled sticks and the like.

However, this solar collector has the disadvantage that the construction tends to be complicated because the collector is placed on the roof finishing plate in the valley between the tile bars and a transparent cover such as glass is provided on top of the collector. be. In addition, there are problems in which the transparent cover becomes cloudy due to dust, etc., which prevents solar heat from being absorbed sufficiently by the collector, and in which it is difficult to absorb atmospheric heat, such as on cloudy days with high temperatures. , this has the disadvantage that the overall thermal efficiency is low.

The present invention has been made in view of the above circumstances, and its purpose is to provide a heat collecting and dissipating device that is efficient, has a simple structure, and is easy to install. Hereinafter, the present invention will be explained in detail with reference to the drawings.

Figures 1 to 3 show an embodiment of the present invention, and reference numeral 1 in the figures is a flexible flat container made of plastic film such as vinyl or polyethylene. An inlet 2a and an outlet 2b of a pipe 2 constituting a circulation passage are connected to the upper and lower parts, respectively. These inlet 2a and outlet 2b are both connected to a flow path 1b formed within the container 1.
An air vent 2c is formed on the inlet 2a side of the pipe 2 to communicate the outside with the circulation passage.

Inside the container 1, three compartments 1a are arranged in the direction of inclination of the tile and stick roof. The sections 1a are communicated with each other by a flow path 1b. The flow path 1b includes a first flow path 1b1 that is provided on one side of the compartment 1a (the left side in FIG. 1) and communicates with the inlet 2a side (water inlet side) of the pipe 2, and
a second flow path 1b2 provided on the other side (right side in FIG. 1) and communicating with the outlet 2b side (water output side) of the pipe 2.

The first flow path 1b1 and the second flow path 1b2 are formed by first and second partition walls 1d1 and 1d2 that partition the first and second flow paths 1b1 and 1b2 from the section 1a. The first partition wall 1d1 is suspended from the upper side of the section 1a. Further, the second partition wall 1d2 extends directly above the lower side of the section 1a.

An air hole 1c and a communication hole 1e1 are formed in the upper and lower parts of the first partition wall 1d1 to communicate the first flow path 1b1 and the section 1a.

On the other hand, the second partition wall 1d2 has a second flow path 1
A communication hole 1e2 is formed that communicates b2 with the section 1a. The position of the communication hole 1e2 is such that the lower end thereof is set lower than the lower end of the air hole 1c formed in the first partition wall 1d1, and the lower end thereof is set higher than the upper end of the communication hole 1e1. The position of is set,
Water is allowed to stay inside the compartment 1a.

The second flow path 1b2 that communicates with the above-mentioned upper section 1a is connected to the first channel 1b2 that communicates with the lower section 1a.
The flow path 1b1 is formed.

Note that the flow path 1 communicating with the lowermost section 1a
b2 is communicated with the outlet 2b of the pipe 2.

The heat collection/dissipation device 3 configured as described above is installed between the tile rods 4 of a roof with tile rods, and as shown in FIG. 3, when water is supplied to the heat collection/dissipation device 3, Roofing iron plates (roof finishing plates) 5 are provided so as to be in close contact with each other. Further, a roof structural material (roof base plate) 7 is provided on the lower surface of the heat collecting and dissipating device 3 via a waterproof roofing 6. In addition, in some cases, waterproof roofing 6 and roof structural material 7
A heat insulating layer may be provided between them.

Next, the operation of the heat collecting and dissipating device 3 according to the present invention will be explained.

First, when water is circulated inside the heat collecting and dissipating device 3, the roofing iron plate 5 is heated by solar heat or atmospheric heat on sunny days or cloudy days when the temperature is high, and the heat is transferred to the container 1. Therefore, the water in the container 1 is heated and can be used as a heat collector. In addition, since the container 1 is divided at appropriate intervals and the amount of expansion is regulated by the roofing iron plate 5, the hydrostatic pressure applied to the lower part of the container 1 can be small, and the container 1 will not be ruptured or swelled unnecessarily due to water pressure. There is nothing to do. Furthermore, an air hole 1c is formed in the first partition wall 1d1 to communicate the first flow path 1b1 and the section 1a, and the second partition wall 1
A communication hole 1e2 that communicates the second flow path 1b2 and the section 1a is formed in d2, and the inlet 2a of the pipe 2
Since the air vent 2c is formed on the side,
Even if the internal pressure of each compartment 1a rises due to solar heat or atmospheric heat, the air in each compartment 1a will not flow to the outside through the air hole 1c of each air chamber 1a, the second flow path 1b2, the communication hole 1e2, and the air vent 2c. It can flow out. Therefore, it is possible to prevent the internal pressure from increasing excessively not only in the upper compartment 1a but also in the lower compartment 1a. It is possible to prevent an accident in which the tube itself ruptures due to excessive expansion. In addition, in winter, plot 1a
Even when the water inside freezes and increases in volume and compresses the air inside, it is possible to prevent an accident in which the container 1 itself ruptures due to this air.

In addition, for night-time cooling in the summer, if this heat collection and radiation device 3 is connected to the heat storage tank of a compression heat pump device and hot water from the heat storage tank is circulated to the heat collection and radiation device 3, heat from the hot water passing through the container 1 can be transferred to the roof. It can be emitted to the outside through the roofed iron plate 5, and can be used as a heat radiator. Conversely, in the case of a heating and hot water supply system using a compression type heat pump device, the circulating water of the heat collection and radiation device 3 can be used as the heat source water of the compression type heat pump device.

In addition, if a solar cell is placed on the roofing iron plate 5 on which the heat collecting and dissipating device 3 according to the present invention is installed and water is circulated through the heat collecting and dissipating device 3, the heat from the solar cell will be absorbed and the power generated by the solar cell will be increased. It is possible to maintain high efficiency. Further, as shown in FIG. 4, if a water dispersion 8 such as synthetic fiber is placed inside each compartment 1a of the container 1, the flow rate of water can be moderated and the heat collection and radiation effect can be improved. Furthermore, in preparation for draining the water in the container 1, a structure may be adopted in which a drainage channel to the outdoors is connected to the lower part of each compartment 1a of the container 1, and a drain plug is provided.

As explained above, the present invention provides a flexible structure in which the interior is divided at appropriate intervals between the roof finishing board and the roof base board of a tile stick roof, and each compartment is interconnected. A flat container is provided on the lower surface of the roof finishing board so that water can be brought into close contact with the bottom surface when water is poured, and the inlet and outlet of the pipes constituting the circulation passage are connected to the container, respectively.
It has a simple structure, is easy to construct, is inexpensive, durable, and has excellent effects such as good heat collection and radiation efficiency.

Moreover, even if the inside of each compartment is heated by solar heat or atmospheric heat and the internal air pressure increases, the air can flow out to the outside through the air hole, flow path, communication hole, and air vent. This prevents the internal pressure from rising excessively not only in the upper compartment but also in the lower compartment, preventing the container from expanding and pushing up the roofing iron plates, causing leaks, or This can prevent accidents such as the container itself bursting due to excessive expansion of the container. Furthermore, even in winter, the risk of the container itself bursting can be reduced.
