Device for enhancing performance of a fan assembly

Abstract

A device for enhancing performance of a fan assembly includes a frame member, a joining part and a plurality of rectifying parts. The rectifying parts are disposed between and connecting with the frame member and the joining part and provide a first passage at a lateral side thereof and a second passage at another lateral side thereof for receiving a guide flow part of the fan assembly.

1 . A device for enhancing performance of a fan assembly, comprising: 
 a frame member;    a joining part; and    a plurality of rectifying parts, being disposed between and connecting with the frame member and the joining part, providing a first passage at a lateral side thereof and a second passage at another lateral side thereof for receiving a guide flow part of the fan assembly;    wherein, the fan assembly provides a fan frame, a fan blade set, a connecting part and a drive part with the fan blade set being attached to the drive part and the drive part being joined to the connecting part.    
   
   
       2 . The device for enhancing performance of a fan assembly as defined in  claim 1 , wherein the frame member and the fan frame provide fixing holes for the frame member and the fan frame being joined to each other by means of fasteners engaging with the fixing holes.  
   
   
       3 . The device for enhancing performance of a fan assembly as defined in  claim 1 , wherein the frame member provides locating parts and the fan frame provides fixing holes corresponding to the locating parts such that the frame member and fan frame are joined to each other by way of the locating parts fitting with the fixing holes.  
   
   
       4 . The device for enhancing performance of a fan assembly as defined in  claim 1 , wherein the connecting part provides locating parts and the joining part provides fixing holes corresponding to the locating parts such that the fan frame and the frame member are joined to each other by means of the locating parts fitting with the fixing holes.  
   
   
       5 . The device for enhancing performance of a fan assembly as defined in  claim 1 , wherein the connecting part provides a plurality of indentations at the circumferential edge thereof for being attached to the guide flow part such that the frame member and the fan frame being joined to each other.  
   
   
       6 . The device for enhancing performance of a fan assembly as defined in  claim 1 , wherein the rectifying parts extend outward the frame member.  
   
   
       7 . The device for enhancing performance of a fan assembly as defined in  claim 1 , wherein the guide flow part extends outward the fan frame.  
   
   
       8 . The device for enhancing performance of a fan assembly as defined in  claim 1 , wherein the guide flow part is flush with the frame member.  
   
   
       9 . The device for enhancing performance of a fan assembly as defined in  claim 1 , wherein the guide flow part is flush with the fan frame.
