At least one adsorbent material is present in the vacuum insulation body. The adsorbent material is partly or completely arranged in the region of the opening.
Claims14
A vacuum insulation body comprising:
- at least one vacuum-tight casing, with at least one vacuum region surrounded by the casing, and
- at least one flow distributor, wherein
- the casing is provided with at least one opening forming an evacuation port for evacuating the vacuum region, and the vacuum insulation body incorporates an adsorbent material and a core material, wherein
- the adsorbent material is formed from at least one dryer and/or a getter, wherein
- the adsorbent material is located directly before the evacuation port as well as in regions directly adjacent to the evacuation port, wherein
- the at least one flow distributor serves to increase an effective evacuation cross-section, and the flow distributor is formed by an adsorbent material, wherein, during evacuation, said flow distributor is arranged in a flow direction before the evacuation port, and wherein
- the flow distributor is formed as a pebble bed, which is located in a receptacle permeable to gas, wherein
- the adsorbent material is arranged such that gas passing through the opening passes through the adsorbent material during vacuum generation.
