Description

{HEAT INSULATING DEVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a heat insulating device for enhancing a heat insulating effect of a building, a vehicle, and the like, and more particularly to a heat insulating device attachable to a window or the like.

Generally, a window used for a building or a vehicle is made of glass through which visible light can be viewed from the inside to the outside. However, such glass is a major cause of deteriorating the cooling and heating efficiency because heat energy is likely to move due to a relatively large heat conduction rate as compared with other parts of a building or a vehicle.

In addition, when the outside air temperature falls below freezing, the water vapor in the air sublimates and the glass window is frozen to form a glaze. In the case where a castle is formed on a window pane, there is a problem that an outside view is difficult and a view is not secured.

In order to solve this problem, a technique of forming a glass window into a double glass window has been developed. However, the double glass window has a problem that the forming process is complicated, the unit price is high, the weight is heavy, and the weight of the vehicle is also increased when the glass window is used in a vehicle or the like. In addition, if a conventional single glass window is used, the entire glass window must be replaced, which requires a lot of cost and time, and replacement itself may be difficult.

Further, a heat-insulating sheet including a plurality of air caps made of synthetic resin and capable of being adhered to a glass window or the like has been developed. However, such a heat insulating sheet has a problem that light refraction occurs due to the air cap, the external view is difficult, the view is not secured, and it is easily separated from the windshield by external stimulation.

In addition, a transparent heat shielding film was directly developed for glass windows and the like. However, such a heat shield film is complicated and difficult to manufacture, is expensive, and can not regenerate waste glass later. In addition, the temperature of the glass window rises very high due to the heat absorbed from the thermal barrier film, and the glass is broken due to the difference in thermal expansion between the film and the glass.

An object of the present invention is to provide an adiabatic device which is excellent in adiabatic performance, prevents the formation of a film on the glass, and secures transparency.

Another object of the present invention is to provide an adiabatic device that is simple in manufacturing process, reduces manufacturing cost, is easy to install, and is light in weight.

According to an aspect of the present invention, there is provided an adiabatic device comprising a plastic panel and a first spacer disposed on one surface of the plastic panel and integrally formed in a closed curve shape along an edge.

The first spacer may be formed of one or more of metal and plastic.

The distance between the first surface of the first spacer contacting the plastic panel and the second surface facing the first surface may be between 3 mm and 12 mm.

One or both sides of the plastic panel may be functionally coated.

And a moisture absorber disposed inside the first spacer.

And a first film disposed on an opposite surface of one side of the plastic panel on which the first spacer is disposed. The first film may be at least one functional film of a graffiti preventing film, an insulating film, a privacy protecting film, a UV blocking film, a solar barrier film and a sound insulating film.

And a second film disposed between the plastic panel and the first spacer. The second film may be at least one functional film of a light-scattering film, a heat insulating film, a privacy film, a UV blocking film, a solar barrier film and a sound insulating film.

The first spacer may further include a second spacer disposed on an opposite side of one side of the second film on which the first spacer is disposed, the first spacer being disposed in a closed curve along the edge of the second film and integrally formed.

And a third film disposed between the second film and the second spacer. The third film may be at least one functional film of a shrinkage preventing film, an insulating film, a privacy protecting film, a UV blocking film, a solar barrier film and a sound insulating film.

INDUSTRIAL APPLICABILITY The heat insulating device according to the present invention has an excellent heat insulating performance, prevents the formation of gaps on the glass, and has an effect of securing the transmittance at the same time. Further, the heat insulating apparatus according to the present invention is simple in manufacturing process and can reduce the cost.

When the adiabatic device 100 is attached to the glass 10, the air space a sealed between the glass 10 and the plastic panel 110 is formed by the first spacer 120. Such a closed air layer (a) can serve as a heat insulating layer.

At this time, the first spacer 120 may be integrally formed. When the first spacer 120 is integrally formed, it is advantageous to seal the air layer (a), and the heat insulating performance can be improved.

The first spacer 120 may be formed of one or more of metal and plastic.
