Fan Module

Abstract

The present invention relates to a fan module ( 10 ) that is comprised of a stationary fan element ( 1 ) and of a movable fan element ( 2 ) that has the ability to rotate. The fan module ( 10 ) has contact surfaces ( 5 ) on an outside lateral surface ( 4 ) that can be used to supply an operating voltage to an electric motor of the fan module ( 10 ). Consequently, a fan module ( 10 ) according to the invention can be quickly assembled and disassembled, allowing it to be replaced during continuing operation.

1 . Fan module comprised of 
 a stationary fan element ( 1 ) and    a movable fan element ( 2 ), positioned with the ability to rotate, and the latter is partially enclosed by the stationary fan element ( 1 ), intended to generate an air flow, and the movable fan element ( 2 ) can be made to rotate by way of an electric motor    wherein contact surfaces ( 5 ;  41 ) are arranged on an outside lateral surface ( 4 ) of the stationary fan element ( 1 ) for supplying an operating voltage for the electric motor.    
     
     
         2 . Fan module as claimed in  claim 1   wherein latching media ( 6 ;  43 ) are envisioned on the stationary fan element ( 1 ) for latching the fan module ( 10 ;  40 ) inside a fan housing ( 9 ;  44 ), into which the fan module ( 10 ;  40 ) is inserted.    
     
     
         3 . Fan module as claimed in  claim 1   wherein clamping media are envisioned on the stationary fan element for fastening the fan module ( 10 ) by way of clamping into a fan housing ( 9 ), into which the fan module ( 10 ) is inserted.    
     
     
         4 . Fan module as claimed in  claim 1   wherein a function display ( 7 ) is envisioned on the stationary fan element ( 10 ) indicating the functional capabilities of the fan module ( 10 ).    
     
     
         5 . Fan module as claimed in one of the  claims 1  to  4  
 wherein the contact surfaces are formed by partially springy contact pins ( 41 ).  
 
     
     
         6 . Fan module as claimed in  claim 5   wherein the contact pins ( 41 ) are supported by a contact clip ( 42 ) that is plugged onto the stationary fan element ( 1 ).    
     
     
         7 . Fan element as claimed in  claim 6   wherein the contact clip ( 42 ) consists of a plastic injection molded part and has two springy latching sections ( 44 ) that are arranged perpendicular in relation to a middle section of the contact clip.    
     
     
         8 . Fan housing for accommodating fan modules ( 10 ) as claimed in one of the  claims 1  to  7  wherein plug-in slots are envisioned for several fan modules ( 10 :  40 ) inside the fan housing ( 9 ;  44 ), and wherein spring or sliding contact surfaces or stationary contact surfaces are arranged in such a way that, in the inserted state of the fan module ( 10 ;  40 ), the spring or sliding contacts or stationary contact surfaces act in conjunction with the contact surface ( 5 ;  41 ) of the fan module ( 10 ;  40 ).  
     
     
         9 . Fan housing as claimed in  claim 8   wherein spring or sliding contacts for several fan modules ( 10 ;  40 ) are fastened on a joint circuit board ( 13 ;  46 ).    
     
     
         10 . Fan housing as claimed in  claim 6  or  9  
 wherein several fan modules ( 10 ;  40 ) can be accommodated in series and in several rows ( 11 ,  12 ) adjacent to each other.
