Radiator with integrated header tank and pump

Abstract

A radiator ( 10 ) with molded plastic header tanks ( 14,18 ) has an electric coolant pump and housing assembly ( 20 ) integrally formed with the outlet header tank ( 18 ). A first half ( 24 ) of the pump housing is integrally molded into the header tank ( 18 ) and a low point and across a smooth and wide transition. The second half of the pump housing ( 26 ) mates at a sealed circular seam to the first half, with an electric coolant pump ( 28 ) held closely inside the two. No fasteners are needed to mount the pump, and the assembly minimizes parts and potential leak points.

1 . An integrated vehicle radiator  10 ) and coolant pump assembly ( 20 ), comprising in combination; 
 a radiator ( 10 ) having a pair of header tanks ( 14 .  18 ) and a an intermediate core ( 12 ), one of said header tanks ( 14 , 18 ) having a first pump housing half ( 24 ) integrally formed therewith,    a second pump housing half ( 26 ) mated to said first pump housing half ( 24 ), and,    an electric coolant pump ( 30 ) contained within said first ( 24 ) and second ( 28 ) pump housing halves.    
     
     
         2 . An integrated vehicle radiator ( 10 ) and coolant pump assembly ( 20 ) according to  claim 1 , further characterized in that said one header tank is an outlet tank ( 18 ) and said first pump housing half ( 24 ) is located on said outlet tank at a low point relative to said radiator ( 10 ).  
     
     
         3 . An integrated vehicle radiator ( 10 ) and coolant pump assembly ( 20 ) according to  claim 1 , further characterized in that said first pump housing half ( 24 ) and header tank ( 18 ) are an integrally molded plastic part.  
     
     
         4 . An integrated vehicle radiator ( 10 ) and coolant pump assembly ( 20 ) according to  claim 1  in which said first ( 24 ) and second ( 26 ) pump housing halves are generally cylindrical in shape at mate at a circular seam.
