Evaporator for a refrigeration device

Abstract

The evaporator for a refrigeration device includes a hydrophobic coating on the surface thereof to inhibit the icing of the evaporator during operation and to reduce the generation of noises arising from relative displacements between the evaporator and the ice attached thereto. The evaporator is a lamellar evaporator and has a pipeline through which a refrigerant flows and a surface in thermally conductive contact with the pipeline. The surface is a heat-exchange surface and has a hydrophobic layer of oil thereon.

1 . An evaporator for a refrigeration device, comprising: 
 a pipeline through which a refrigerant flows; and    a surface thermally conductively connected to said pipeline, said surface being a heat-exchange surface and having thereon a hydrophobic layer of oil.    
   
   
       2 . The evaporator according to  claim 1 , wherein: 
 said pipeline has a pipeline surface having thereon said hydrophobic layer of oil; and    said heat-exchange surface has thereon said hydrophobic layer of oil.    
   
   
       3 . The evaporator according to  claim 1 , wherein said pipeline has an outer surface having thereon said hydrophobic layer of oil.  
   
   
       4 . The evaporator according to  claim 1 , wherein said pipeline and said surface form a lamellar evaporator.  
   
   
       5 . A lamellar evaporator for a refrigeration device, comprising: 
 a hollow pipe for conveying a refrigerant therethrough; and    a lamellar heat-exchange surface thermally conductively connected to said pipe surface, said heat-exchange surface being at least partially coated with a hydrophobic layer of oil.    
   
   
       6 . The evaporator according to  claim 1 , wherein said pipeline has an outer surface at least partially coated with said hydrophobic layer of oil.
