Description

Technical Field

[0001] The utility model relates to the technical field of heat preservation, in particular to a vacuum heat insulation cover. Background Art

[0002] A vacuum heat shield is a device used to maintain a high vacuum state and effectively isolate heat transfer, and is commonly used in scientific research, industrial processing, and other applications. The interior of a vacuum heat shield is usually maintained in a high vacuum state, and air is pumped out by a pump to reduce the conduction and convection heat transfer of gas molecules to reduce heat conduction. In the fields of physics, chemistry, astronomy, etc., vacuum heat shields are often used to protect high-precision instruments or laboratory devices from external heat. In industrial processes such as semiconductor manufacturing, optical coating, and vacuum freezing, vacuum heat shields are used to control process environments and thermal effects.

[0003] As shown in the announcement number CN 204309192 U, a vacuum heat insulation cover is disclosed, including a shell, the interior of the shell is a hollow cavity structure, a vacuum layer and an aerogel heat insulation layer are arranged in the cavity, the vacuum layer and the aerogel heat insulation layer are separated by a partition, the number of the vacuum layer and the aerogel heat insulation layer are both multiple layers, and the number of the vacuum layer and the aerogel heat insulation layer is equal, and the multiple layers of the vacuum layer and the multiple layers of the aerogel heat insulation layer are arranged in sequence. By arranging a vacuum layer in the cavity, since the vacuum cannot conduct heat, the heat loss is reduced. In addition, the use of thermal insulation materials can be reduced by using a vacuum pumping method, which can reduce costs to a certain extent. Utility Model Content
