Heat Exchanger

Abstract

The present disclosure provides a heat exchanger, including flat tubes and at least one fin, wherein each flat tube includes a first tube section, a bent tube section and a second tube section, which are connected in sequence; a plurality of flat tubes are provided, and the plurality of flat tubes are arranged in an array; and an extension direction of each fin is perpendicular to an extension direction of the each flat tube, the each fin is connected to at least a part of the plurality of bent tube sections, and the each fin shields at least a part of the structures of the plurality of bent tube sections.

What is claimed is: 
     
         1 . A heat exchanger, comprising:
 a plurality of flat tubes, wherein each flat tube comprises a first tube section, a bent tube section and a second tube section which are connected in sequence, the plurality of flat tubes are arranged in an array, and there is a gap between two adjacent bent tube sections; and   at least one fin, wherein an extension direction of each fin is perpendicular to an extension direction of the each flat tube, the each fin is connected to at least a part of the plurality of bent tube sections, and the each fin shields gaps in a plurality of bent tube sections.   
     
     
         2 . The heat exchanger as claimed in  claim 1 , wherein the each fin comprises a baffle, a first end plate and a second end plate, the first end plate and the second end plate are respectively arranged on two ends of the baffle, the baffle shields one sides of the plurality of bent tube sections, and the first end plate and the second end plate are connected to two bent tube sections among the plurality of bent tube sections in a one-to-one correspondence manner. 
     
     
         3 . The heat exchanger as claimed in  claim 2 , wherein a plurality of fins are provided, a baffle of at least one of the plurality of fins shields first sides of the plurality of bent tube sections, and the baffles of the other fins among the plurality of fins ( 20 ) shield second sides of the plurality of bent tube sections. 
     
     
         4 . The heat exchanger as claimed in  claim 1 , wherein,
 the each fin is provided with a plurality of grooves, the plurality of grooves are formed at intervals in a length direction of the each fin, and at least a part of each bent tube section is located in one of the plurality of grooves.   
     
     
         5 . The heat exchanger as claimed in  claim 4 , wherein a number of the grooves is equal to that of the bent tube sections, and the plurality of bent tube sections are arranged in one-to-one correspondence with the plurality of grooves. 
     
     
         6 . The heat exchanger as claimed in  claim 5 , wherein a part of the each fin, which is located between two adjacent bent tube sections, is of an arc-shaped structure, a flat plate structure or a V-shaped structure. 
     
     
         7 . The heat exchanger as claimed in  claim 4 , wherein a number of the grooves is greater than a number of the bent tube sections; and there is at least one groove, which does not match the bent tube sections, between two adjacent bent tube sections. 
     
     
         8 . The heat exchanger as claimed in  claim 1 , wherein the each fin comprises a plurality of folded plates, wherein the plurality of folded plates are connected in sequence, two adjacent folded plates in the plurality of folded plates are arranged to form a V-shaped structure, and one bent tube section is arranged between two adjacent folded plates. 
     
     
         9 . The heat exchanger as claimed in  claim 1 , wherein the each fin is made of an aluminum foil. 
     
     
         10 . The heat exchanger as claimed in  claim 1 , wherein an electric potential of the each fin is lower than an electric potential of each bent tube section.
