Radiator for a motor of an air compressor

Abstract

A radiator for a motor in an air compressor has a tubular casing enclosing the motor. The tubular casing has a plurality of fins radially formed on a body thereof. Two of the fins are longer than the others, and each has an opening defined at an edge thereof. The long fins are engaged with a base of the air compressor by fasteners extending between the base and the openings of the longer fins. A cooling fan is rotatably mounted on an axle extending from the motor and adjacent the fins.

What is claimed is:  
     
         1 . A radiator for a motor ( 10 ) in an air compressor ( 1 ), the radiator comprising: 
 a tubular casing ( 20 ) enclosing the motor ( 10 ), the tubular casing ( 20 ) having a plurality of fins ( 21 ) radially formed on an outer periphery thereof.    
     
     
         2 . The radiator as claimed in  claim 1 , wherein two fins ( 21   a ) are longer than the other fins ( 21 ) and opposed to each other, each longer fin ( 21   a ) having an opening ( 22 ) defined at an edge thereof, and engaged with a base ( 40 ) of the air compressor ( 1 ) by a respective one of two fasteners ( 23 ) securely extending between the openings ( 22 ) of the longer fins ( 21   a ) and the base ( 40 ).  
     
     
         3 . The radiator as claimed in  claim 1  further comprising a cooling fan ( 30 ) rotatably mounted on an axle ( 11 ) extending from the motor ( 10 ), whereby the cooling fan ( 30 ) draws air across the plurality of fins ( 21 ) and ( 21   a ).
