The present invention relates to a heat insulating chassis structure having improved heat conduction rate, and more particularly, to a heat insulating chassis structure having an outer air chamber and an inner chamber with an air layer therebetween, (1.0 W / m < 2 > K or less), and the heat conduction ratio is improved.

In general, with the development of architectural technology, various buildings, especially high-rise buildings, have been constructed with reinforced glass walls so that the structure like a sliding window gradually disappears and the function of projecting light from outside or projecting to the outside can be improved Construction.

When a part or the whole of the outer wall of the building is made of tempered glass, the construction of the building is such that a supporting frame such as a curtain wall fixed to the building structure by using a fixing member is installed vertically and horizontally, And the fixing glass is fixed to the outer wall of the building structure.

In addition, in the conventional outer wall of the building, a window is installed at a predetermined position so as to be opened and closed for ventilation to the inside of the building, and the tempered glass can be fixed to the window.

And windows are largely divided into materials according to materials, and they are divided into plastic, aluminum and other (steel, stainless steel, etc.), and plastic and aluminum are representative. Plastics have good thermal performance, good elasticity and good chemical durability, but their strength is weak and their use is limited due to low ignition temperature and toxic gas emission in case of fire.

It is desirable that aluminum has higher strength, less expansion and contraction, excellent durability, and higher ignition temperature than conventional plastic materials, but aluminum material has higher thermal conductivity and convection current There is a disadvantage in that a large loss is caused by Most of the deterioration of window performance is due to the heat loss of the aluminum frame.
