Metal honeycomb type vacuum multi-layer attenuation heat insulation plate

Abstract

The invention discloses a metal honeycomb type vacuum multi-layer attenuation heat insulation plate. A multi-layer honeycomb structure is machined by adopting vacuum fusion welding, and the overall thickness is much lower than that of an existing single-layer honeycomb structure heat insulation plate. Heat transfer can be effectively blocked through multi-layer vacuum. Compared with an existing honeycomb heat insulation plate, the metal honeycomb type vacuum multi-layer attenuation heat insulation plate has the advantages of being light in structure, small in thickness, high in strength, long in service life and easy to machine and form, saving occupied space by 90% compared with traditional heat insulation materials, being capable of being widely applied to household appliances such as water heaters and refrigerators, thermos bottles, vacuum cups, household kitchen electric appliances and the like except for heat insulation and heat preservation of traditional buildings, traffic tools and large devices, greatly reducing heat loss, providing device energy consumption standards and completely eradicating fire risks caused by high temperature on electric devices, having the ultrathin size and the metal structure, being capable of being applied to the field where many traditional heat insulation materials cannot be applied, making a great contribution to energy conservation and emission reduction and being quite wide in application range.

Description

technical field [0001] The invention relates to a metal honeycomb vacuum multi-layer attenuation insulation board. Background technique [0002] Existing thermal insulation boards are generally sandwich structures, that is, mainly composed of heat-insulating materials in the middle and panels covering the upper and lower surfaces of the heat-insulating materials. Thermal insulation materials are mostly made of materials with large porosity, resulting in a large thickness of the entire insulation board, and the thickness of the thinnest existing insulation board is also more than 10mm. [0003] Moreover, this type of insulation board is made of non-metallic material, which leads to poor reworkability of the insulation board, and cannot be processed into other shapes by heat treatment such as welding. Moreover, due to the large overall thickness, the traditional insulation board is only suitable for insulation of buildings and large equipment. It takes up a lot of space and c...
