Vacuum sorption device

Abstract

A vacuum sorption device includes a volume area, in which a sorbent which periodically sorbs and desorbs a refrigerant is situated and which is formed at least partially enclosed by a condenser. The condenser is bounded by an outer wall of the volume area and a further enclosure wall. Alternately at least one of the outer wall and the enclosure wall is provided with embossments oriented toward the respective other wall to fix a flow gap width in the condenser.

What is claimed is: 
     
         1 . A vacuum sorption device, comprising a volume area ( 1 ), in which a sorbent ( 2 ) which periodically sorbs and desorbs a refrigerant is situated and which is formed at least partially enclosed by a condenser ( 3 ), the condenser ( 3 ) being bounded by an outer wall ( 4 ) of the volume area ( 1 ) and a further enclosure wall ( 5 ), wherein alternately the outer wall ( 4 ) and/or the enclosure wall ( 5 ) is/are provided with embossments ( 6 ) oriented toward the respective other wall ( 4 ,  5 ) to fix a flow gap width in the condenser. 
     
     
         2 . The vacuum sorption device according to  claim 1 , wherein a gap, which is defined by the embossments ( 6 ), between the outer wall ( 4 ) and the enclosure wall ( 5 ) is formed less than 2 mm wide. 
     
     
         3 . The vacuum sorption device according to  claim 1 , wherein the embossments ( 6 ) are situated uniformly distributed on the enclosure wall ( 5 ) and at a distance of between 10 to 40 mm, preferably 20 to 30 mm from one another. 
     
     
         4 . The vacuum sorption device according to  claim 1 , wherein the embossments ( 6 ) are formed in the shape of spherical caps and preferably have a diameter of 1 to 2 mm. 
     
     
         5 . The vacuum sorption device according to  claim 1 , wherein the outer wall ( 4 ) of the volume area ( 1 ) and the enclosure wall ( 5 ) are formed as cylindrical. 
     
     
         6 . The vacuum sorption device according to  claim 5 , wherein a collector housing ( 7 ) is situated on at least one end of the cylindrically formed enclosure wall ( 5 ). 
     
     
         7 . The vacuum sorption device according to  claim 6 , wherein the collector housing ( 7 ) is integrally formed from material of the enclosure wall ( 5 ) and is preferably in the form of a bead. 
     
     
         8 . The vacuum sorption device according to  claim 6 , wherein a connection ( 8 ) for alternately supplying or removing a fluid is provided on the collector housing ( 7 ). 
     
     
         9 . The vacuum sorption device according to  claim 8 , wherein connections ( 8 ) on the collector housings ( 7 ) are situated offset to one another with respect to the circumference. 
     
     
         10 . The vacuum sorption device according to  claim 1 , wherein the enclosure wall ( 5 ) is formed as a prefinished part having the embossments ( 6 ) and preferably so it can be pushed onto the at least one collector housing ( 7 ) on the outer wall ( 4 ), which is formed free of embossments ( 6 ).
