Control device for fluid pressure and flow direction

Abstract

A control device for fluid pressure and flow direction includes a fan and a frame member. The fan has an inlet and an outlet and the frame member provides at least a first opening and a second opening at two lateral sides thereof. A middle solid part is disposed in the frame member extending to the second opening from the first opening in a way of gradual convergence. A flow passage is formed between the middle solid part and the frame member with an end thereof at the second opening side being greater than the other end at the first opening side. Therefore, the fluid is controlled to increase or decrease the pressure thereof, decrease noise and flow direction.

1 . A control device for fluid pressure and flow direction, comprising: 
 a fan, providing an inlet and an outlet; and    a frame member, providing at least a first opening at one lateral side thereof and a second opening at another side thereof and having a middle solid part therein extending to the second opening from the first opening in a way of gradual convergence;    wherein, a flow passage is formed between the middle solid part and the frame member and the flow passage at the second opening side is greater than that at the first opening.    
   
   
       2 . The control device for fluid pressure and flow direction as defined in  claim 1 , wherein the second opening is connected to the inlet side of the fan.  
   
   
       3 . The control device for fluid pressure and flow direction as defined in  claim 1 , wherein the first opening is connected to the outlet side of the fan.  
   
   
       4 . The control device for fluid pressure and flow direction as defined in  claim 1 , wherein the first opening is connected to the inlet side of fan.  
   
   
       5 . The control device for fluid pressure and flow direction as defined in  claim 1 , wherein the second opening is connected to the outlet side of the fan.  
   
   
       6 . The control device for fluid pressure and flow direction as defined in  claim 1 , wherein at least a static wing is joined to the inner wall of the frame member and the middle solid part.
