No-Frost Cooling Device

Abstract

An evaporator unit for a no-frost cooling device which comprises an evaporator, a tubular heating device and a housing which surrounds the evaporator and the tubular heating device. Said tubular heating device comprises a plurality of parallel tubular sections which are connected together in such a manner that they form a single piece. Two parallel tubular sections which are directly adjacent to each other are located at the beginning and at the end of the tubular heating device.

1 - 8 . (canceled) 
   
   
       9 . A no-frost cooling device having an evaporator, a tubular heating device and a housing for the evaporator and the tubular heating device, with the tubular heating device including a plurality of one piece contiguous substantially parallelly extending tube sections, the cooling device comprising at least two closely adjacent, parallely extending tube sections disposed at a first beginning portion and a second ending portion of the tubular heating device. 
   
   
       10 . The no-frost cooling device according to claim  8  wherein two parallel tube sections on opposite sides of the tubular heating device are directly connected by a tube bend. 
   
   
       11 . The no-frost cooling device according to  claim 9  wherein the tube bend and the parallel tube sections are coplanar. 
   
   
       12 . The no-frost cooling device according to  claim 9  wherein the tube bend extends outside the plane of the parallel tube sections. 
   
   
       13 . The no-frost cooling device according to  claim 9  wherein the tubular heating device is fixed at the height of tube bends connecting the parallel tube sections to projections of the housing. 
   
   
       14 . The no-frost cooling device according to  claim 12  wherein the projections include at least one first projection disposed in contact with an outer portion of a center section of the tube bend, and a second projection disposed in contact with an inner portion at both ends of the tube bend. 
   
   
       15 . The no-frost cooling device according to  claim 13  wherein the first projection forms a hook surrounding the tube bend.
