Cooling system having variable orifice plates

Abstract

A cooling system for an engine is disclosed. The cooling system may have an engine, a pump configured to receive coolant from the engine and generate a flow of coolant, and a heat exchanger configured to receive the coolant flow. The cooling system may also have a plurality of orifice plates located between the pump and the heat exchanger. At least one of the plurality of orifice plates may be adjustable to control the flow of the coolant from the engine to the heat exchanger.

1 . A method of installing a power system comprising:
 installing an engine;   installing a heat exchanger configured to receive and cool pressurized coolant from the engine; and   adjusting at least one of a plurality of orifice plates to control coolant flow from the engine to the heat exchanger based on a distance from an installation location of the engine to an installation location of the heat exchanger.   
     
     
         2 . The method of claim  13 , wherein adjusting includes:
 measuring the distance between the installation location of the engine and the installation location of the heat exchanger;   indexing a first orifice plate of the plurality of orifice plates based on the measured distance; and   installing the first orifice plate.   
     
     
         3 . The method of claim  14 , wherein indexing the first orifice plate includes aligning an indicia on the first orifice plate with a reference indicia on a second orifice plate of the plurality of orifice plates. 
     
     
         4 . The method of claim  13 , further including adjusting the at least one of the plurality of orifice plates to control coolant flow from the engine to the heat exchanger based on a pressure drop across a pump.
