Combined protective container

Abstract

The invention discloses a combined type protection container which belongs to the field of thermal insulation and refractory apparatus. The container comprises an inner shell and an outer shell, wherein, the interior of the inner shell is provided with a sealed cavity, the space between the inner shell and the outer shell is filled with thermal insulation materials, at least one layer of vacuum layer structure is arranged around the inner shell in the outer shell and the vacuum layer structure is composed of a cup-shaped vacuum body and a vacuum cup cover which is matched with the vacuum body. The combined type protection container of the invention is a multi-layer combined structure which is composed of the vacuum layer and the thermal insulation materials and has good insulation effect on the conductivity, the convection and the radiation of heat. The combined type protection container can provide high temperature insulation protection for storage devices and electronic devices inside the container. The combined type protection container has wide application area and can be applied to fields such as vessel black boxes and fire protection administration. In addition, the combined type protection container has the advantages of stable performance, convenient material selection and low manufacturing costs.

Description

technical field [0001] The invention relates to the field of heat insulation and refractory equipment, in particular to a composite protective container. Background technique [0002] In fields with heat insulation requirements, such as fire management or ship navigation information recording, special containers are often used to store data storage devices or electronic devices with recorded data information. Such containers are usually made of refractory materials such as asbestos. The main function of using refractory materials is to delay heat conduction and convection, but the delay effect on heat radiation is less, and it is almost impossible to directly reduce the amount of heat radiation. In high temperature environments, the heat transferred in the form of radiation cannot be ignored. Frequently, severe damage or even complete destruction of preserved items is caused. Therefore, simply utilizing the container made of heat insulating material has been unable to meet...

Problems solved by technology

The main function of using refractory materials is to delay heat conduction and convection, but the delay effect on heat radiation is less, and it is almost impossible to directly reduce the amount of heat radiation. In high temperature environments, the heat transferred in the form of radiation cannot be ignored. Often causes severe damage, or even complete destruction, to preserved items

Therefore, simply using the container made of heat-insulating material can no longer meet the requirements for storing special items in a high-temperature environment.
