Fan serial connection structure

Abstract

A fan serial connection structure includes a series fan assembly and a connection member. The series fan assembly includes a first fan and a second fan correspondingly serially connected with the first fan. The connection member is disposed on one side of the series fan assembly. The connection member has a first face and a second face opposite to the first face. The first face is correspondingly assembled with the side of the series fan assembly. According to the above structural design, the co-vibration of the series fan is offset or restrained to greatly reduce the vibration of the fan and lower the noise.

What is claimed is: 
     
         1 . A fan serial connection structure comprising:
 a series fan assembly including a first fan and a second fan correspondingly serially connected with the first fan, the first fan having a first fan frame and a first flow passage passing through the first fan frame, the second fan having a second fan frame and a second flow passage passing through the second fan frame, the second flow passage communicating with the first flow passage; and   a connection member disposed on one side of the series fan assembly, the connection member having a first face and a second face opposite to the first face, the first face being correspondingly assembled with the side of the series fan assembly.   
     
     
         2 . The fan serial connection structure as claimed in  claim 1 , wherein the connection member is formed with multiple perforations passing through the connection member from the first face to the second face, the side of the series fan assembly being formed with multiple through holes corresponding to the perforations, multiple locking members being passed through the perforations and the through holes. 
     
     
         3 . The fan serial connection structure as claimed in  claim 1 , wherein the first and second fans are serially connected with each other by a means selected from a group consisting of engagement, locking, insertion, adhesion and latching. 
     
     
         4 . The fan serial connection structure as claimed in  claim 1 , wherein the connection member further includes at least one assembling member formed with a passageway, the assembling member being assembled with the series fan assembly. 
     
     
         5 . The fan serial connection structure as claimed in  claim 4 , wherein the assembling member has a first end face and a second end face opposite to the first end face, the passageway passing through the assembling member from the first end face to the second end face. 
     
     
         6 . The fan serial connection structure as claimed in  claim 5 , wherein the first fan further has a first opening and a second opening opposite to the first opening, the first flow passage being defined between the first and second openings, the second fan further having a third opening and a fourth opening opposite to the third opening, the second flow passage being defined between the third and fourth openings, the fourth opening correspondingly communicating with the second opening. 
     
     
         7 . The fan serial connection structure as claimed in  claim 6 , wherein the assembling member is disposed between the second and fourth openings, the first end face being assembled with the second opening, while the second end face being assembled with the fourth opening, the passageway correspondingly communicating with the first and second flow passages. 
     
     
         8 . The fan serial connection structure as claimed in  claim 7 , wherein the series fan assembly is assembled with the assembling member by means of engagement, locking, insertion, adhesion, slide rail or latching. 
     
     
         9 . The fan serial connection structure as claimed in  claim 6 , wherein the connection member has two assembling members respectively disposed at the first and third openings and assembled with the first and third openings, the passageways of the assembling members respectively correspondingly communicating with the first and second flow passages. 
     
     
         10 . The fan serial connection structure as claimed in  claim 9 , wherein the series fan assembly is assembled with the assembling members by means of engagement, locking, insertion, adhesion, slide rail or latching. 
     
     
         11 . The fan serial connection structure as claimed in  claim 4 , wherein the assembling member is formed with multiple assembling sections, the series fan assembly being formed with multiple connection sections correspondingly assembled with the assembling sections. 
     
     
         12 . The fan serial connection structure as claimed in  claim 11 , wherein the assembling sections are holes, sockets, mortises or posts. 
     
     
         13 . The fan serial connection structure as claimed in  claim 11 , wherein the connection sections are holes, sockets, mortises or posts.
