Radiator

Abstract

A radiator includes a supporting part including a plurality of through openings formed therein and a plurality of cooling tubes, each of the cooling tubes received in at least one of the through openings formed in the supporting part, each of the cooling tubes having a generally U-shaped configuration, wherein a first one of the cooling tubes includes a first helical portion having a first pre-determined depth and a second one of the cooling tubes includes a second helical portion having a second pre-determined depth different from the first pre-determined depth.

         7 . A radiator comprising:
 a supporting part including a plurality of through openings formed therein;   a first cooling tube received in at least a first one of the through openings formed in the supporting part, the first cooling tube having a first helical portion with a first pre-determined depth; and   a second cooling tube received in at least a second one of the through openings formed in the supporting part, the second cooling tube having a second helical portion with a second pre-determined depth, wherein the second pre-determined depth is greater than the first pre-determined depth.   
     
     
         8 . The radiator according to  claim 7 , wherein the supporting part includes an even number of through openings to receive both ends of each of the cooling tubes. 
     
     
         9 . The radiator according to  claim 7 , wherein the cooling tubes are concentrically arranged to substantially align each of the cooling tubes along a single plane. 
     
     
         10 . The radiator according to  claim 7 , wherein the second cooling tube is disposed adjacent the first cooling tube and arranged inside a U-shaped configuration of the first cooling tube. 
     
     
         11 . The radiator according to  claim 7 , wherein the first helical portion is a helical groove formed in a wall of the first cooling tube. 
     
     
         12 . The radiator according to  claim 7 , wherein the second helical portion is a helical groove formed in a wall of the second cooling tube. 
     
     
         13 . The radiator according to  claim 7 , wherein the through openings are arranged in a linear configuration. 
     
     
         14 . A radiator comprising:
 a supporting part including a plurality of through openings formed therein;   a first cooling tube received in at least a first one of the through openings formed in the supporting part, the first cooling tube having a helical portion with a first pre-determined depth;   a second cooling tube received in at least a second one of the through openings formed in the supporting part, the second cooling tube having a helical portion with a second pre-determined depth, wherein the second pre-determined depth is greater than the first pre-determined depth; and   a third cooling tube received in at least a third one of the through openings formed in the supporting part, the third cooling tube having a helical portion with a third pre-determined depth, wherein the third pre-determined depth is greater than the second pre-determined depth.
