Heat Exchanging Tube

Abstract

A heat exchanging tube including a guiding tube and a fin module is disclosed. The guiding tube includes a channel forming two openings at two ends of the guiding tube. The fin module is arranged in the channel of the guiding tube and includes a partition. The partition has a first retaining edge and a second retaining edge. The first and second retaining edges are coupled with an inner wall of the guiding tube. The partition includes a first face and a second face between the first and second retaining edges. The first face includes a first fin unit and the second face includes a second fin unit. A first channel is formed between the first face of the partition and the inner wall of the guiding tube, and a second channel is formed between the second face of the partition and the inner wall of the guiding tube.

What is claimed is: 
     
         1 . A heat exchanging tube comprising:
 a guiding tube having a channel, wherein the channel forms two openings at two ends of the guiding tube; and   a fin module arranged in the channel of the guiding tube and including a partition, wherein the partition has a first retaining edge and a second retaining edge, wherein the first and second retaining edges are coupled with an inner wall of the guiding tube, wherein the partition comprises a first face and a second face between the first and second retaining edges, wherein the first face comprises a first fin unit and the second face comprises a second fin unit;   wherein a first channel is formed between the first face of the partition and the inner wall of the guiding tube, and wherein a second channel is formed between the second face of the partition and the inner wall of the guiding tube.   
     
     
         2 . The heat exchanging tube as claimed in  claim 1 , wherein the first fin unit is integrally formed with the first face of the partition and extends towards the inner wall of the guiding tube, and wherein the second fin unit is integrally formed with the second face of the partition and extends towards the inner wall of the guiding tube. 
     
     
         3 . The heat exchanging tube as claimed in  claim 1 , wherein the first fin unit is capable of being affixed to or removed from the first face of the partition and extends towards the inner wall of the guiding tube, and wherein the second fin unit is capable of being affixed to or removed from the second face of the partition and extends towards the inner wall of the guiding tube. 
     
     
         4 . The heat exchanging tube as claimed in  claim 1 , wherein each of the first and second fin units has a plurality of fins, wherein each of the plurality of fins of the first fin unit has a first abutting edge abutting with the inner wall of the guiding tube, and wherein each of the plurality of fins of the second fin unit has a second abutting edge abutting with the inner wall of the guiding tube. 
     
     
         5 . The heat exchanging tube as claimed in  claim 1 , wherein the first and second channels are isolated from each other. 
     
     
         6 . The heat exchanging tube as claimed in  claim 1 , wherein the first fin unit has a plurality of fins parallel to and spaced from each other. 
     
     
         7 . The heat exchanging tube as claimed in  claim 1 , wherein the second fin unit has a plurality of fins parallel to and spaced from each other. 
     
     
         8 . The heat exchanging tube as claimed in  claim 1 , wherein the first fin unit has a plurality of fins, wherein the second fin unit has a plurality of fins having the same quantity as that of the plurality of fins of the first fin unit, and wherein each of the plurality of fins of the first fin unit is aligned with a corresponding one of the plurality of fins of the second fin unit. 
     
     
         9 . The heat exchanging tube as claimed in  claim 1 , wherein two opposing guiding grooves are formed on the inner wall of the guiding tube, and wherein the first and second retaining edges are respectively engaged with the two guiding grooves. 
     
     
         10 . The heat exchanging tube as claimed in  claim 9 , wherein each guiding groove forms a positioning portion adjacent to one of the two openings, and wherein the first and second retaining edges of the partition are positioned on the positioning portions of the two guiding grooves.
