Method and device for housing component

Abstract

The present invention related to a method and a device for reducing the number of water vapor molecules per unit volume in a housing ( 1 ) by providing an end ( 11 ) of the housing ( 1 ) which has a lower thermal inertia than the rest of the housing with perforations ( 15 ). When the temperature outside the housing ( 1 ) falls some of the more energetic water vapor molecules in the housing ( 1 ) will leave the housing ( 1 ) via the perforations ( 15 ) and a small number of the less energetic molecules will enter the housing from the surroundings. This will lead to a nett flow of water vapor molecules out of the housing ( 1 ).

1 . Housing for components characterised in that said housing ( 1 ) has at least one first side ( 11 ,  11 ′) which has a lower thermal inertia than other sides ( 7 ,  7 ′,  9 ,  13 ) of said housing, wherein said first side is perforated by at least one through hole ( 15 ,  15 ′):  
     
     
         2 . Housing for components characterised in that said housing ( 1 ) has at least one first portion of a side ( 11 ,  11 ′) which has a lower thermal inertia than the other portions of said housing, wherein said first portion of a side is perforated by at least one through hole ( 15 ,  15 ′).  
     
     
         3 . Housing according to claims  1  or  2  characterised in that said through hole ( 15 ,  15 ′) has a diameter or maximum width of between 20 mm and 0.01 mm.  
     
     
         4 . Housing according to any of the previous claims characterised in that said through hole ( 15 ,  15 ′) has a maximum diameter or width of between 5 mm and 0.5 mm.  
     
     
         5 . Housing according to any of the previous claims characterised in that said first side ( 11 ,  11 ′) or portion of a side is made of the same material as the rest of the sides ( 7 ,  7 ′,  9 ,  13 ) of said housing ( 1 ) but is thinner.  
     
     
         6 . Housing according to any of the previous claims characterised in that said first side ( 11 ,  11 ′) or portion of a side is made of a material which is different to the material out of which the rest of the sides ( 7 ,  7 ′,  9 ,  13 ) of said housing ( 1 ) are made from.  
     
     
         7 . Housing according to any of the previous claims characterised in that first side ( 11 ,  11 ′) or portion of a side is thermally insulated from the rest of said housing ( 1 ) by a thermal insulator ( 17 ).  
     
     
         8 . Method for reducing the number of water vapour molecules per unit volume in a housing ( 1 ) having sides ( 7 ,  7 ′,  9 ,  11 ,  11 ′,  13 ) characterised by the steps of perforating one of said sides ( 11 ,  11 ′) with at least one through hole ( 15 ,  15 ′) and reducing the thermal inertia of the perforated side ( 11 ,  11 ′).  
     
     
         9 . Method for reducing the number of water vapour molecules per unit volume in a housing ( 1 ) having sides ( 7 ,  7 ′,  9 ,  11 ,  11 ′,  13 ) characterised by the steps of perforating one of said sides ( 11 ,  11 ′) with at least one through hole ( 15 ,  15 ′) and providing a thermal insulator ( 17 ) between said perforated side ( 11 ,  11 ′) and the other sides ( 7 ,  7 ′,  9 ,  11 ,  11 ′).  
     
     
         10 . Method for reducing the number of water vapour molecules per unit volume in a housing ( 1 ) having sides ( 7 ,  9 ,  11 ,  11 ′,  13 ) characterised by the steps of perforating one of said sides ( 11 ,  11 ′) with at least one through hole ( 15 ,  15 ′), reducing the thermal inertia of the perforated side ( 11 ,  11 ′) providing a thermal insulator ( 17 ) between said perforated side ( 11 ,  11 ′) and the other sides ( 7 ,  7 ′,  9 ,  11 ,  11 ′).
