Vacuum pipe and refrigerator

Abstract

The invention provides a vacuum pipe. The vacuum pipe comprises an outer pipe, an inner pipe and end part sealing pieces, wherein the outer pipe is arranged outside the inner pipe in a sleeving mode, and the outer pipe and the inner pipe are arranged in a spaced mode; and the end part sealing pieces are configured to be arranged between the outer pipe and the inner pipe in a clamped mode so as to seal and fix the outer pipe and the inner pipe, and a vacuum cavity is defined among the outer pipe, the inner pipe and the end part sealing piecez. According to the vacuum pipe, convective heat transfer can be reduced by vacuumizing a space between the two layers of pipes which are \ sealed in a closed mode; and the end part sealing pieces are arranged between the two layers of pipes in a clamped mode to seal and fix the two layers of pipes, and a certain distance can be kept between the outer pipe and the inner pipe all the time, so that the structure of the whole vacuum pipe is stable, the independent appearance structure is kept, and the vacuum cavity can be kept in a stable vacuum state.

Description

technical field [0001] The invention relates to the technical field of refrigeration and freezing devices, in particular to a vacuum tube and a refrigerator. Background technique [0002] The traditional stand-alone refrigerator integrates the refrigeration system and the box body. Usually the refrigeration system needs to occupy a large volume, resulting in a limited internal volume of the box body, and because the box body usually needs to make way for the refrigeration system, the local shape of the box body Special, complex process. In addition, since the size of the stand-alone refrigerator is fixed, the location of the refrigerator is relatively single, which cannot meet the needs of users for adjusting the location of the refrigerator. Contents of the invention [0003] It is an object of the present invention to provide a piping which reduces losses in the transfer of cooling. [0004] A further object of the present invention is to provide a refrigerator in whic...
