Evaporator

Abstract

The present invention relates to an evaporator ( 1 ) comprising a sheet ( 2 ) and a microchannel tube ( 3 ) used in the cooling cycle, having channels (K) parallel to each other wherein the refrigerant flows.

1 . An evaporator ( 1 ) comprising a sheet ( 2 ) and a microchannel tube ( 3 ) used in the cooling cycle, having arranged channels (K) parallel to each other wherein
 the refrigerant flows, characterized by a microchannel tube ( 3 )   fixed on the sheet ( 2 )   by bending around the axis (E) that is vertical to the sheet ( 2 ) and on which the channels (K) are in line,   such that only one of its channels (K) will be in contact.   
     
     
         2 . An evaporator ( 1 ) as in  claim 1 , characterized in that the microchannel tube ( 3 ) has a rectangular cross section, wherein the channels (K) are arranged side by side on the wide edge and which is fixed to the sheet ( 2 ) from over the narrow edge. 
     
     
         3 . An evaporator ( 1 ) as in  claims 1  and  2 , characterized in that the microchannel tube ( 3 ) being fastened on the sheet by bending in serpentine form. 
     
     
         4 . An evaporator ( 1 ) as in  claims 1  and  2 , characterized in that the microchannel tube ( 3 ) being fastened on the sheet by bending in spiral form. 
     
     
         5 . An evaporator ( 1 ) as in any one of the above claims, characterized by one or more than one support member ( 4 ) fixed on the sheet ( 2 ) whereon the microchannel tube ( 3 ) bears in the direction of the axis (E) whereon the channels (K) are arranged in line. 
     
     
         6 . An evaporator ( 1 ) as in  claim 5 , characterized in that the support member ( 4 ) extends along the microchannel tube ( 3 ) in accordance with the shape of the microchannel tube ( 3 ). 
     
     
         7 . An evaporator ( 1 ) as in  claim 5 , characterized in that the support member ( 4 ) has a plate shape that has almost the same width as the microchannel tube ( 3 ). 
     
     
         8 . An evaporator ( 1 ) as in  claim 5 , characterized in that the support member ( 4 ) is shaped as a pin. 
     
     
         9 . An evaporator ( 1 ) as in  claim 5 ,  6 ,  7  or  8 , characterized in that the support member ( 4 ) bears on the inner side of the bend portion (B) of the microchannel tube ( 3 ) bent in serpentine form. 
     
     
         10 . An evaporator ( 1 ) as in  claims 5  to  9 , characterized in that the microchannel tube ( 3 ) being fixed on the sheet ( 2 ) by being passed under one and over the other one of the support members ( 4 ) and thus by being compressed between the support members ( 4 ). 
     
     
         11 . An evaporator ( 1 ) as in any one of the above claims, characterized by being used in a cooling device wherein the evaporation processes both in the freezing and the cooling chambers are realized by only one microchannel tube ( 3 ).
