Dual radiator engine cooling module - single coolant loop

Abstract

An engine cooling system for a motor vehicle having a dual radiator assembly plumbed in parallel within a single coolant loop to provide improved engine cooling.

What is claimed is: 
     
         1 . A radiator assembly for use in an engine cooling system of a motor vehicle, comprising:
 a first radiator unit having a first inlet and a first outlet;   a second radiator unit having a second inlet and a second outlet;   an inlet hose assembly having a first inlet hose connected to said first inlet, a second inlet hose connected to said second inlet, an inlet supply hose, and an inlet connector interconnecting said inlet supply hose to both of said first and second inlet hoses; and   an outlet hose assembly having a first outlet hose connected to said first outlet, a second outlet hose connected to said second outlet, an outlet supply hose, and an outlet connector interconnecting said outlet supply hose to both of said first and second outlet hoses.   
     
     
         2 . The radiator assembly of  claim 1  wherein said first radiator unit is larger than said second radiator unit. 
     
     
         3 . The radiator assembly of  claim 1  wherein a thickness dimension of a first core for said first radiator unit is equal to a thickness dimension of a second core for said second radiator unit. 
     
     
         4 . The radiator assembly of  claim 1  wherein said first radiator unit is disposed between a blower fan and said second radiator unit. 
     
     
         5 . The radiator assembly of  claim 1  wherein said inlet hose assembly is supplied with coolant exiting the engine and said outlet hose assembly supplies coolant to a water pump. 
     
     
         6 . A radiator assembly for use in an engine cooling system of a motor vehicle having a water pump and a fluid flow circuit through which coolant is circulated between the engine and the water pump, the radiator assembly comprising:
 a first radiator unit having a first inlet and a first outlet;   a second radiator having a second inlet and a second outlet;   an inlet hose assembly having an inlet supply hose in fluid communication with the fluid flow circuit to receive coolant from the engine, a first inlet hose connecting said inlet supply hose to said first inlet, and a second inlet hose connecting said inlet supply hose to said second inlet, and   an outlet hose assembly having an outlet supply hose in fluid communication with the fluid flow circuit to supply coolant to the water pump, a first outlet hose connecting said outlet supply hose to said first outlet, and a second outlet hose connecting said outlet supply hose to said second outlet.   
     
     
         7 . The radiator assembly of  claim 6  wherein said first radiator unit is larger than said second radiator unit. 
     
     
         8 . The radiator assembly of  claim 6  wherein a thickness dimension of a first core for said first radiator unit is equal to a thickness dimension of a second core for said second radiator unit. 
     
     
         9 . The radiator assembly of  claim 6  wherein said first radiator unit is disposed between a blower fan and said second radiator unit. 
     
     
         10 . The radiator assembly of  claim 6  wherein said inlet hose assembly includes an inlet coupling interconnecting said inlet supply hose to said first and second supply hoses, and wherein said outlet hose assembly includes an outlet coupling interconnecting said outlet supply hose to said first and second outlet hoses.
