Abstract:
1. An engine cooling system including both a primary cooling system having a coolant conduit carrying coolant for cooling said engine and an induced flow secondary cooling system, wherein coolant flows from upstream to downstream through said coolant conduit of said primary cooling system, said primary cooling system comprising: a flow restrictor disposed within a tubular member which is removably connected in serial fluid communication with said coolant conduit of said primary cooling system in said coolant conduit of said primary cooling system, said flow restrictor creating a differential pressure thereacross in response to coolant flow through said coolant conduit of said primary cooling system, wherein the pressure on the upstream side of said flow restrictor is greater than the pressure on the downstream side of said flow restrictor; a port disposed on said tubular member and communicating with said coolant conduit upstream of said flow restrictor; said induced flow secondary cooling system comprising: a peripheral heat exchanger communicating with said port and receiving coolant from said coolant conduit of said primary cooling system, wherein coolant flow to said peripheral heat exchanger is induced by said differential pressure across said flow restrictor in said coolant conduit of said primary cooling system.
