Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a solar collector having a double pane structure and VIP insulation,

[0001] The present invention relates to a solar panel type solar collector having a double-pane structure and a VIP (Vacuum Insulation Panel) insulation, and more particularly to a solar panel having a dual window structure including glass, air And the VIP composite heat insulation material which is formed by composite of the VIP insulation material and the existing thermal insulation material is installed to maximize the heat collection efficiency at the high temperature by minimizing the heat loss rate of the collector, And a solar panel type solar collector to which a double pane structure transparent body and a VIP insulation material are applied, which can be applied at a high efficiency in a high temperature utilization range corresponding to a conventional vacuum tube collector.

The solar collector absorbs the solar energy and stores the absorbed heat energy. As a result, two categories of technologies can be applied to enhance the performance of the collector. One technique is to increase the absorptivity of the absorber by increasing the efficiency of the absorber, and the second is to use absorbed heat energy without loss.

However, in recent years, the use of a flat plate type solar collector has been limited in spite of its many merits, while the use range of the solar collector has become increasingly high. The flat plate type solar collectors have a high initial efficiency of the collector, but the heat loss through the collector and the back insulation is high, so its use is limited for high temperature applications.

Particularly, the heat loss of the collector is the largest due to the heat loss through the glass plate. Therefore, it is difficult to reduce the heat loss through the glass plate because the light transmittance must be increased.

Hereinafter, embodiments of the present invention will be described.

FIG. 1 is a perspective view illustrating a partial cross-section of a solar panel plate type collector according to an embodiment of the present invention, in which a transparent body having a double-pane structure and VIP insulation is applied. FIG. Sectional view showing a solar flat plate type collector to which VIP insulation is applied.

The heat plate type heat collectors 100 of the present invention referenced in these drawings are formed of a case 10, a transmitting body 20, a heat collecting plate 30, a copper pipe 40, a header portion 50, 60).

The case 10 is preferably formed in a rectangular box shape and is formed as a space in which the upper surface is opened. In the space, the heat collecting plate 30 and the copper pipe 40 are installed, Thereby forming an air chamber 110 sealed inside.

The air chamber 110 is divided into an upper air chamber 111 and a lower air chamber 112 by a heat collecting plate 30.

 The permeable body 20 is formed to be sealed on the upper surface of the case 10 so that rainwater, foreign matter and the like are prevented from entering the case 10 from the outside.

The transparent body 20 is formed of a front transparent body 21 having a thickness of 2.5 to 3.5 mm so as to seal the inside of the case 10 and to transmit solar heat and sunlight to facilitate heat insulation performance and transmittance, A rear transparent body 22 formed of a polymer material and having a thickness of 3.0 mm so as to be spaced apart from the front transparent body 21 so as to facilitate the thermal conductivity and a rear transparent body 22 formed between the front transparent body 21 and the rear transparent body 22 And a plurality of hollow layers (23) inside the partition walls (24).

The hollow layer 23 is filled with air or an incombustible gas to prevent the heat in the case 10 from being conducted to the outside.

In order to improve the heat insulation performance of the front transparent body 21, a conventional single-pane window glass is used in conventional collectors to solve the problem of high solar light transmittance and poor heat loss. The outermost layer is made of 3.0 mm glass, and the lower layer is formed of a hollow layer (inert gas) to reduce heat conduction, and a rear transparent body 22 is used thereunder.

Here, in the conventional technique, the rear transparent body 22 is mainly made of glass, but the weight is heavy and the thermal conductivity is worse than that of the polymer. Therefore, the present invention uses a polymer material having a high light transmittance and is superior to glass in terms of heat loss.

In order to increase the heat insulating efficiency of the hollow layer 23, the hollow layer 23 is designed to have a longitudinal or transverse partition 24 structure having a width of about 100 mm to suppress gas flow in each partition 24, The loss characteristics are excellent. And the infrared radiation loss from the surface of the transmitting body 20 through the infrared reflective coating (Low-E) on the surface of the transmitting body 20 can be reduced. The transmission body 20 adopting this technology is characterized in that infrared radiation of high-temperature thermal energy absorbed in the absorber can be cut off secondarily. By applying this technique of transmitting body 20, the heat loss can be reduced more than twice as compared to the conventional transmitting body.

In the method of forming the hollow layer 23, the front transmitting body 21 has a plate-like shape, and the rear transmitting body 22 has a plate-like structure having a trough structure to have the hollow layer 23 And the two plate-shaped structures are bonded to form a hollow layer 23. At this time, as the mutual bonding method, a bonding material having a curing property by UV irradiation is used. It has high light transmittance, high mechanical strength, high stability of bonding process and high process speed.

In addition, the components of the heat collecting device 100 include a heat collecting plate 30 provided in the case 10 below the permeable body 20 so as to collect solar energy and a heat collecting plate 30 formed integrally with the heat collecting plate 30 A plurality of copper pipes 40 for absorbing heat of solar energy collected from the heat collecting plate 30 by a working fluid conveyed therein to transfer heat to the copper pipes 40, The header portion 50 that receives the heat of the heat exchanger 40 and transfers the heat to the outside is similar to the conventional flat plate type solar flat plate type collector, and thus does not describe the detailed detailed structure, structure, and function.

According to the characteristic structure of the present invention, however, the heat collecting plate 30 and the copper pipe 40 are positioned in the air chamber 110 of the case 10, And is divided into an air chamber 111 and a lower air chamber 112.

Accordingly, the copper pipe 40 is formed in a structure in which the heat exchange efficiency is improved by the heat transfer method by the radiant heat generated in the upper air chamber 111 and the lower air chamber 112 in addition to the solar energy directly received from the transmitting body 20 .

The VIP composite insulating material 60 supports the lower ends of the heat collecting plate 30, the copper pipe 40 and the header 50 and insulates the high temperature collected at the heat collecting plate 30 from the outside.

The VIP composite insulating material 60 includes a VIP board 61 provided at a lower end of the heat collecting plate 30 and connected to the case 10 by an encapsulating unit 63 using a sealing technique, A copper pipe 40 and a urethane foam 62 formed to support the lower ends of the header portion 50. As shown in FIG.

The encapsulant 63 is durable by a high temperature epoxy (EPOXY) molding method so as to ensure durability at a high temperature. An encapsulation layer is formed of an inorganic heat insulating material on the encasement, The board 61 is seated on the inner wall of the case 10 and assembled.

As described above, the rear surface insulation technology applied to the solar panel type solar collector 100 mainly uses glass fiber, rock surface, and urethane which are thermal insulation materials for buildings. It is necessary to improve the heat insulating property of the collector 100 in order to be applied to the solar thermal cooling and solar thermal industrial use system. Therefore, in the present invention, a VIP (Vacuum Insulation Panel) which has been developed recently and is recognized as superior in heat insulating property is used.

The VIP board 61 is mainly applied to the electronic industry and the household appliance industry and can be regarded as a technology introduction stage. In order to apply the VIP technology to the solar flat panel type collector 100, the gas barrier performance at high temperature can be secured In the present invention, in the sealing process of the sealing part 63, a high-temperature epoxy (EPOXY) which is capable of securing durability at a high temperature by breaking away from the conventional film heat sealing method, ) Molding method was applied to ensure the durability of the encapsulation part.

Thus, the durability of the sealing part 63 is secured within the stagnant temperature condition of 200 to 250 ° C. of the collector 100, thereby ensuring long-term durability of the collector. The technique applied in the present invention makes it possible to suppress the heat loss of each weak portion by applying a technique of composite molding the VIP material having such durability to the collector case 10.

The present invention is applied to a building or the like by means of a facility such as a pedestal as in the well-known method, and the collector 100 installed so as to absorb the heat of solar energy and transfer the heat source to a necessary place, And the heat source thus used is returned to the collector 100 and circulated in such a way that it is heated by the heat of solar energy.
