Problems solved by technology

[0004] However, the heat bridge phenomenon (Heat Bridge, a phenomenon in which heat flows through the edge of the vacuum heat insulating material) and the durability of the vacuum heat insulating material are in a conflicting relationship with each other, so there is a limit to the production of an effective vacuum heat insulating material

Embodiment 1

[0198]The vacuum heat insulating element 100 of Example 1 has an aluminum (Al) deposition layer 135 composed of three layers and the first skin material 130 including a barrier layer 170, and the vacuum heat insulating element 100 of Example 2 omits the barrier layer 170, And has a first skin material 130 including an aluminum aluminum (Al) deposition layer 135 composed of three layers.

[0199] The vacuum heat insulating material 100 of Example 1 has the extended part 150 attached, and the vacuum heat insulating material 100 of Example 2 has the extended part 150 which was not bonded.

[0200] As shown in Table 1, the vacuum heat insulating material 100 of Example 1 has a lower effective thermal conductivity than the vacuum heat insulating material 100 of Example 2. The vacuum heat insulating material 100 of Example 1 is also lower than the vacuum heat insulating material 100 of Example 2 in terms of the difference in center thermal conductivity with the lapse of time, so it ...

Abstract

Disclosed are: a vacuum insulating material having an improved structure so as to improve a heat-insulating property and durability; and a refrigerator including the same. The vacuum insulating material comprises: a core material; a first outer cover material disposed at the outer side of the core material; a blocking layer disposed between the core material and the first outer cover material; and a second outer cover material coupled with the first outer cover material such that an accommodating space for accommodating the core material and the blocking layer therein is formed, wherein the blocking layer is fused or adhered to the first outer cover material so as to be integrated with the first outer cover material.

Description

technical field [0001] The present invention relates to a vacuum heat insulating member and a refrigerator including the same, and more particularly, to a vacuum heat insulating member having an improved structure to improve heat insulation and durability and a refrigerator including the same. Background technique [0002] The energy that human beings can consume is limited, and the global warming caused by carbon dioxide produced by energy utilization has become the biggest problem facing human beings together with the energy crisis. Therefore, the energy regulations of various countries are increasingly strengthened, and the energy rating system for home appliances is an eternal issue for manufacturers. Government energy ratings requiring maximum efficiency with little energy are well suited to the needs of consumers requiring high internal volume and low power consumption. In particular, a great deal of research has been conducted on refrigerators over the past several d...
