Fan housing

Abstract

Embodiments of the present disclosure include a fan housing having a first part with a first side wall and a first back wall, a second part having a second side wall and a second back wall, where the first back wall and the second back wall meet to define an axle opening and the first and second side walls meet to define a right circular cylinder parallel with the axle opening. The first part and second part of the housing can be mirror images when positioned with the first and second sidewalls and the edge of the first and second back walls facing each other. Embodiments of the fan housing can also include a motor casing that extends from the first and second back walls away from the first and second side walls. The motor casing can contain and house a motor for turning the impeller contained in the housing.

1 . A fan housing, comprising:
 a first part having a first side wall and a first back wall; and   a second part having a second side wall and a second back wall, where the first back wall and the second back wall meet to define an axle opening and the first side wall and the second side wall define a right circular cylinder parallel with the axle opening.   
   
   
       2 . The fan housing of  claim 1 , where the first part is a mirror image of the second part. 
   
   
       3 . The fan housing of  claim 1 , including an outlet port cut through one of the first side wall and the second side wall. 
   
   
       4 . The fan housing of  claim 1 , where the first back wall and the second back wall define a concave surface. 
   
   
       5 . The fan housing of  claim 1 , where the first back wall and the second back wall define a convex surface. 
   
   
       6 . The fan housing of  claim 1 , further including a shroud that extends between the first side wall and the second side wall, the shroud having an opening to allow fluid flow in a direction of the axle into the fan housing. 
   
   
       7 . The fan housing of  claim 1 , including a motor casing that extends from the first and second back walls away from the first and second side walls. 
   
   
       8 . The fan housing of  claim 7 , where the motor casing includes a first section that extends from the first back wall and a second section that extends from the second back wall. 
   
   
       9 . The fan housing of  claim 8 , where the first section and the second section are mirror images of each other. 
   
   
       10 . A fan, comprising
 a motor;   an axle coupled to the motor, where the axle rotates;   an impeller coupled to the axle; and   a housing that surrounds at least a portion of the impeller, the housing having a first part and a second part that join at an edge that intersects the axle.   
   
   
       11 . The fan of  claim 10 , where the first part and the second part are mirror images of each other. 
   
   
       12 . The fan of  claim 10 , where the edge bisects the axle. 
   
   
       13 . The fan of  claim 10 , where the first part and the second part when joined at the edge define an axle opening that completely surrounds the axle. 
   
   
       14 . The fan of  claim 13 , where the first part of the housing includes a first side wall and the second part includes a second side wall, and the first and second side walls define a right circular cylinder parallel with the axle opening through the housing. 
   
   
       15 . The fan of  claim 10 , where the housing includes a motor support to which the motor is releasably coupled. 
   
   
       16 . The fan of  claim 15 , where the housing includes a motor casing that surrounds at least a portion of the motor. 
   
   
       17 . A method of forming a fan housing, comprising:
 molding a first part of the fan housing;   molding a second part of the fan housing, where the second part is a mirror image of the first part; and   joining the first part and the second part along an edge that meets at an axle opening defined by the first part and the second part.   
   
   
       18 . The method of  claim 17 , where molding the first part and the second part includes using a thermoset material to mold the first part and the second part. 
   
   
       19 . The method of  claim 17 , including cutting an outlet port through a wall of one of the first part and the second part. 
   
   
       20 . The method of  claim 17 , including molding a first section and a second section of a motor casing; and
 joining the first and second sections of the motor casing to the first part and the second part of the fan housing.   
   
   
       21 . The method of  claim 20 , including molding the first section and the second section of the motor casing as mirror images of each other. 
   
   
       22 . The method of  claim 17 , where joining the first part and the second part along the edge includes fusing the first part to the second part along the edge.
