High efficiency fluid delivery system

Abstract

A high efficiency fluid delivery system which is particularly useful in delivering temperature-controlled air in convection heating or cooling apparatuses is described. The fluid delivery system preferably comprises fluid circulation means having an intake opening for the fluid and vanes that assist in increasing fluid velocity and reducing turbulent flow.

1 . A fluid delivery system, comprising:
 a first fluid circulation member comprising an intake opening for fluid; and   at least one vane mounted adjacent the intake opening, wherein the at least one vane is disposed in a substantially radial position relative to a center point of the intake opening.   
     
     
         2 . The system of  claim 1 , wherein the vane is disposed in a substantially horizontal position. 
     
     
         3 . The system of  claim 1 , wherein said fluid is a gas or air. 
     
     
         4 . The system of  claim 1 , wherein the first fluid circulation member comprises a first blower having a first blower wheel for circulating temperature controlled gas within the system, the first blower wheel comprising the intake opening;
 a second blower having a second blower wheel for circulating temperature controlled gas within the system, the second blower wheel comprising a second intake opening;   a motor operably connected to and which rotates a shaft, each of the first blower wheel and the second blower wheel being connected to the shaft for rotation of the first and second blower wheels by the shaft; and   at least a second vane mounted adjacent the second intake opening of the second blower wheel.   
     
     
         5 . The system of  claim 4 , wherein each of the vanes is disposed in a substantially radial position relative to the center point of the intake opening to which it is adjacent. 
     
     
         6 . The system of  claim 4 , further comprising:
 a third blower having a third blower wheel for circulating temperature controlled gas within the system, the third blower wheel comprising a third intake opening, the third blower wheel being connected to the shaft for rotation of the third blower wheel by said shaft.   
     
     
         7 . A gas delivery system for a heating or cooling apparatus comprising:
 a first blower having a first blower wheel for circulating temperature controlled gas within the apparatus, the blower wheel comprising an intake opening;   a second blower having a second blower wheel for circulating temperature controlled gas within the apparatus, the second blower wheel comprising a second intake opening;   a third blower having a third blower wheel for circulating temperature controlled gas within the apparatus, the third blower wheel comprising a third intake opening;   a motor operably connected to and which rotates a shaft, each of the first blower wheel, the second blower wheel, and the third blower wheel being connected to said shaft for rotation of the blower wheels by the shaft;   a first vane mounted adjacent said intake opening of the first blower wheel and the second intake opening of the second blower wheel; and   a second vane mounted adjacent the second intake opening of the second blower wheel and the third intake opening of the third blower wheel.   
     
     
         8 . The apparatus of  claim 7 , wherein each vane is disposed in a substantially radial position with respect to the center point of the intake opening to which it is adjacent. 
     
     
         9 . The apparatus of  claim 7 , wherein each vane is disposed in a substantially horizontal position. 
     
     
         10 . A method of delivering fluid, comprising:
 providing the apparatus of  claim 1 ; and   reducing turbulence of fluid entering the system adjacent the intake opening via contact of the fluid with the at least one vane.
