Abstract

The invention relates to a vacuum damping element ( 1 ) with a casing ( 2 ) which defines a vacuum region. A thermoelectric element ( 3 ), in particular a Peltier element ( 3 ), is arranged within the vacuum region in order to generate a temperature difference between two regions ( 5 ) provided on the outside of the casing ( 2 ).

         4 . A vacuum insulation body in accordance with  claim 3 , wherein a contact surface between the thermoconductive body and the envelope is larger than a contact surface between the thermoconductive body and the thermoelectric element. 
     
     
         5 . A vacuum insulation body in accordance with  claim 1 , furthermore having a heat exchanger which is arranged outside the vacuum zone, wherein the heat exchanger is thermally coupled to a region of the envelope, preferably in a region whose temperature can be influenced by the thermoelectric element. 
     
     
         6 . A vacuum insulation body in accordance with  claim 1 , characterized in that the envelope comprises a high barrier film or is a high barrier film; and/or in that a core material, in particular Pearlite, is located in the vacuum zone. 
     
     
         7 . A vacuum insulation body in accordance with  claim 5 , characterized in that the heat exchanger itself represents a part of the envelope or the total envelope. 
     
     
         8 . A thermoelectric element, in particular a Peltier element, comprising: at least one n-doped semiconductor element; and at least one p-doped semiconductor element that is connected to the n-doped semiconductor element via a conductor bridge, wherein the two semiconductor elements are spaced apart from one another such that a free space is formed between them, characterized in that
 the free space between the n-doped semiconductor material and the p-doped semiconductor material is filled with a material in powder form, with provision preferably being made that the material in powder form has a mean grain size of a powder grain which is between 5 μm and 30 μm, preferably between 10 μm and 25 μm, and particularly preferably between 15 μm and 20 μm.   
     
     
         9 . A vacuum insulation body having an envelope which defines a vacuum zone,

         10 . A thermally insulated container having at least one carcass and having at least one temperature-controlled inner space, preferably a refrigerator unit and/or a freezer unit having at least one carcass and having at least one refrigerated inner space which is surrounded by the carcass, as well as having at least one closing element by means of which the temperature-controlled inner space and preferably the refrigerated inner space is closable, wherein at least one intermediate space is present between the temperature-controlled inner space and preferably the refrigerated inner space and the outer wall of the container and preferably of the unit,
 characterized in that   at least one vacuum insulation body in accordance with  claim 1  is arranged in the intermediate space.   
     
     
         11 .
