Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hybrid system for generating electricity using a solar heat,

[0001] The present invention relates to a hybrid system using solar heating and cooling and heating. More specifically, the present invention relates to a hybrid system in which a heat collecting panel is formed so as to stably contact and bond to a heating pipe to achieve efficient conduction, The present invention relates to a power generation and cooling / heating hybrid system using solar heat, which generates power by using a temperature change crossing up and down and minimizes heat loss to the outside by forming a hermetically sealed structure by accommodating a heat collecting panel in a case.

Generally, solar collectors are broadly divided into a flat plate type and a vacuum tube type. The flat plate type solar collector generally has a square flat plate shape and absorbs the sunlight to a thin metal plate made of copper or aluminum A plurality of fine pipe tubes made of copper are welded to one surface of the heat collecting plate at predetermined intervals to be inserted into a rectangular frame body and a transparent lid is placed on the upper surface of the rectangular collector plate, .

In the conventional planar type solar collector, sunlight is primarily used to heat the heat collecting plate, and the heated heat collecting plate transfers heat energy to the internal heat generating body formed on one side. The heat exchanging heat medium is joined at the main pipe of the heat collecting unit, To thereby provide heat energy that has been collected in the vessel.

In this case, the flat plate type solar collector may be used by directly heating water. However, in a region where the cold season and the cold season exist, the antifreeze is used as a heating medium rather than the water, and the antifreeze is secondarily heated have.

However, even though the conventional plate type solar collector generally uses a transparent lid at the upper part of the heat collecting tube, heat loss to the outside due to the convection phenomenon during the heat exchange of the heat medium is largely generated and the heat collecting efficiency is usually 50% And the use is restricted in the temperature range of 60 to 70 degrees Celsius or more.

On the other hand, according to the conventional patent document 10-0704750, a vacuum tube type solar collector is vacuumed to block the heat loss due to convection by enclosing the closed space in contact with the solar heat collecting surface.

At this time, the vacuum tube type solar collector uses a main tube and a branch tube to vacuum heat the outside of the collector tube and the collector plate in a state where the collector tube is in contact with the collector tube, and the solar heat collected from the collector plate surface is lost to the outside .

However, when the heat collecting tube and the heat collecting plate are joined to each other, they are simply attached by 'point welding' to the longitudinal direction tip. This is because heat loss is generated due to difficulty in transferring the solar heat collected through the heat collecting plate to the heat collecting tube. Although the heat collecting area per area needs to be maximized, the conventional heat collecting plate is formed as a simple plate material, so that it is difficult to expect high efficiency heat collecting performance.

In addition, the conventional collectors perform only the function of collecting the solar heat, so that it is a limit to utilize the solar heat for the multi purpose purpose.

The heat collecting panel 10 made of the heat collecting surface 10a and the heating pipe 11 contacting the heat collecting ground enlargement part 10b are selected to install the solar heat collecting body. 6 to 7, instead of the collecting ground enlargement part 10b formed at the center of the heat collecting panel 10, the planar collecting part 10c may be used instead of the collecting ground enlargement part 10b when the solar collector is used for the purpose of multi- And a solar heat collector having a heat collecting panel 10 constituting a concave collecting portion 10a at a location facing the planar heat collecting portion 10c is provided at the center. More specifically, The heat collecting panel 10 will be described.

A heat collecting panel (10) comprising a planar heat collecting portion (10c) formed at the center and a concave heat collecting portion (10a) continuous with a planar heat collecting portion (10c) so as to face the planar heat collecting portion (10c) And a lower member 1b which is integrally formed on the bottom surface of the planar heat collecting portion 10c and is connected to the upper member 1a by bolting with the lower member 1a under the upper member 1a, And a housing (1).

A gasket 18 is injected between the upper member 1a and the lower member 1b so that the housing 1 is tightly coupled.

A plurality of heating tubes 2 heated by the heat collected by the flat heat collecting section 10c are inserted into the housing 1. At this time, a plurality of heating tubes 2 are prevented from flowing, A spacing member (4) for conducting the collected heat to the plurality of heating tubes (2) is provided between the plurality of heating tubes (2).

The plurality of spacers 4 are made of a material having a high thermal conductivity.

The heating pipe 2 serves to supply hot water to the inside of the plurality of heating pipes 2. The heating pipe 2 may have a circular shape or a square shape and may have a polygonal shape depending on the purpose of use. According to the various forms of the tube 2, the spacing member 4 also takes the same form, in order to make a perfect contact with the heating tube 2.

[ Which is a phenomenon that an electromotive force is generated due to a temperature difference by being cooled by the gap member 4, and can be used as alternative energy.

In other words, the Seebeck effect is a phenomenon in which an electromotive force is generated when two ends of two kinds of metals are connected to each other and temperatures of both ends thereof are made different. When two kinds of metals are constituted so that one contact is high temperature and the other is low temperature, Current is generated. The magnitude of the electromotive force and the current varies depending on the type of the metal to which it is connected.

When two kinds of metals or semiconductors are connected and a temperature difference is given between two points, an electromotive force is generated and a current flows. The former type is called a heat current, and the electromotive force generated between metal wires is called a thermoelectric power. The magnitude of the thermal current depends on the type of metal mated and the temperature difference between the two contacts.

For example, in a circuit made of copper and constantane, when the temperature difference between two contacts is 100 degrees, an electromotive force of 4.24 mV is generated, and a current flows from the high temperature con- tactant to the low heat current copper .

Therefore, the present invention is characterized by supplying cold and hot water together with power generation according to the purpose of use.
