Fan assembly

Abstract

A fan assembly, configured to be mounted on a casing, includes a fan, two mounting frames, and two fixing elements. The mounting frames are disposed on two opposite sides of the fan, and the mounting frames are detachably disposed on the casing via the fixing elements. The structures and the sizes of the mounting frames are the same.

What is claimed is: 
     
         1 . A fan assembly, configured to be mounted on a casing, comprising:
 a fan comprising a front surface and a rear surface opposite to the front surface;   a first mounting frame, mounted on the fan, comprising:
 a first mounting body disposed on the front surface; and 
 a first fixing portion, disposed on the first mounting body, comprising 
   a first fixing hole;   a first fixing element configured to be mounted in the casing and the first fixing hole;   a second mounting frame, mounted on the fan, comprising:
 a second mounting body disposed on the rear surface; and 
 a second fixing portion, disposed on the second mounting body, comprising a second fixing hole; and 
   a second fixing element configured to be mounted in the casing and the second fixing hole;   wherein the first mounting frame and the second mounting frame have the same structure and size, and the first fixing portion and the second fixing portion are respectively located at two diagonal corners of the fan.   
     
     
         2 . The fan assembly as claimed in  claim 1 , wherein the first mounting frame further comprises a positioning portion disposed on the first mounting body, and the positioning portion comprises a positioning groove, wherein a side of another mounting frame of another fan assembly is located in the positioning groove. 
     
     
         3 . The fan assembly as claimed in  claim 1 , wherein the first mounting frame further comprises a plurality of hooks disposed on the first mounting body, and the hooks are hooked on the fan. 
     
     
         4 . The fan assembly as claimed in  claim 3 , wherein the first mounting frame further comprises a damping arm disposed the first mounting body or the hook, and abutting against the front surface. 
     
     
         5 . The fan assembly as claimed in  claim 1 , wherein the first mounting frame comprises an elastic arm disposed on the first mounting body and configured to abut against the casing, wherein the elastic arm is configured to provide an elastic force to the casing. 
     
     
         6 . The fan assembly as claimed in  claim 1 , wherein the first mounting frame comprises a U-shaped elastic arm disposed on the first mounting body, located under the first fixing portion, and surrounding the first fixing element, wherein the U-shaped elastic arm is configured to provide an elastic force to the casing. 
     
     
         7 . The fan assembly as claimed in  claim 6 , wherein the U-shaped elastic arm comprises a protrusion configured to abut against the casing. 
     
     
         8 . The fan assembly as claimed in  claim 1 , wherein the first fixing portion further comprises a fixing member located in the fixing hole, and the first fixing element further comprises a retaining groove, wherein the fixing member is located in the retaining groove. 
     
     
         9 . The fan assembly as claimed in  claim 1 , wherein the first mounting frame further comprises an abutting member disposed on the first mounting body, and abutting against the front surface, wherein when the first mounting frame is mounted on the fan, the abutting member provides a reaction force to the fan. 
     
     
         10 . The fan assembly as claimed in  claim 1 , wherein the first mounting frame and the second mounting frame are made of plastic, and formed as a single piece.
