Novel heat preserving layer structure

Abstract

The invention relates to a novel heat preserving layer structure. The novel heat preserving layer structure comprises a screw, a T-shaped vacuum main rib, a heat preserving container wall, a vacuum heat insulating layer, a heat preserving layer, bolts, nuts and a protective reflecting layer. The heat preserving layer is connected with the heat preserving container wall through the T-shaped vacuum main rib, and the T-shaped vacuum main rib is connected with the heat preserving layer through special bolts, so that convenience is brought to maintenance and overhauling; through design of the special bolts, creepage is prevented; vacuum pumping is performed between the heat preserving layer and the container wall, so that a good heat preserving effect is achieved; through the protective reflecting layer made of an iron sheet, the heat preserving layer can be protected, and external radiation loss can be reduced; the heat preserving layer is filled with a foam polymer, so that a remarkable heat insulating effect and outstanding economical benefit are achieved.

Description

technical field [0001] The invention relates to a novel insulation layer structure, in particular to a detachable vacuum insulation layer, which belongs to the technical field of thermal engineering. Background technique [0002] In the field of thermal systems, a large number of insulation layers are often laid, and its functions mainly include the following points: to separate the cold and hot environments of the equipment and reduce heat loss. Lay the insulation layer; separate the cold and hot parts in the equipment so that the ambient temperature of the cold part is not higher than the maximum limit of its temperature; reduce the temperature difference between the two sides of the same part and reduce the thermal stress. In the thermal system, the insulation layer is mainly used to divide the cold and hot environment of the equipment to reduce heat loss. The direct contact between the conventional insulated container and the insulation layer, heat convection is inevita...

AI Technical Summary

Problems solved by technology

Conventional insulated containers are in direct contact with the insulation layer, heat convection is inevitable, and cannot play a good insulation effect; some insulated container walls are fixedly connected with the insulation layer, resulting in the failure of the insulation layer, and the equipment cannot be put into operation quickly Production; some use detachable connections, but the connecting bolts are ordinary bolts, which often cause creep due to thermal stress generated by high temperature; therefore, it is particularly important to develop a detachable room insulation layer structure suitable for high temperature environments
