Heat exchanger structure

Abstract

A heat exchanger structure includes a pipe and a flow-guiding element. The pipe internally defines a chamber, in which the flow-guiding element is disposed. The flow-guiding element includes a helical main body and a plurality of turbulence promoters radially outward extended from two opposite lateral sides of the helical main body. The turbulence promoters are independently arranged on the helical main body with free ends of the turbulence promoters contacting with an inner wall surface of the chamber, so that a fin cooling effect is produced. The turbulence promoters and the helical main body together define at least one flow-guiding section. With the helically distributed turbulence promoters of the flow-guiding element, the heat transfer ability and the thermal performance factor of both laminar and turbulent flows in the pipe can be increased to provide excellent heat transfer effect.

1 . A heat exchanger structure, comprising:
 a pipe internally defining a chamber; and   a flow-guiding element being disposed in the chamber; the flow-guiding element including a helical main body and a plurality of turbulence promoters radially outward extended from two opposite lateral sides of the helical main body; the turbulence promoters being independently arranged, and each having a free end facing toward and contacting with an inner wall surface of the chamber; and the turbulence promoters and the helical main body together defining at least one flow-guiding section.   
     
     
         2 . The heat exchanger structure as claimed in  claim 1 , wherein the turbulence promoters are selected from the group consisting of plate-shaped, needle-shaped, bar-shaped, and strip-shaped turbulence promoters. 
     
     
         3 . The heat exchanger structure as claimed in  claim 1 , wherein the flow-guiding element and the chamber together define a helical flow path in the pipe. 
     
     
         4 . The heat exchanger structure as claimed in  claim 1 , wherein the turbulence promoters are spaced from one another by a clearance. 
     
     
         5 . The heat exchanger structure as claimed in  claim 1 , wherein the turbulence promoters are the same in length. 
     
     
         6 . The heat exchanger structure as claimed in  claim 1 , wherein the turbulence promoters are different in length. 
     
     
         7 . The heat exchanger structure as claimed in  claim 1 , wherein the turbulence promoters are spaced from one another by a uniform clearance. 
     
     
         8 . The heat exchanger structure as claimed in  claim 1 , wherein the turbulence promoters are spaced from one another by different clearances.
