Method and system for vehicle thermal management

摘要

A method and system for thermal management includes an engine heat exchanger configured to transfer waste heat from an engine to a heat transfer fluid and an engine exhaust heat exchanger coupled in flow communication with the engine heat exchanger wherein the engine exhaust heat exchanger is configured to transfer heat from an exhaust of the propulsive engine to the pumped heat transfer fluid. A bypass valve is coupled in parallel with the engine exhaust heat exchanger wherein the bypass valve is selectable to modulate a flow of the heat transfer fluid through the engine exhaust heat exchanger and a plurality of accessory heat exchangers that are coupled in flow communication with at least one of the engine heat exchanger and the engine exhaust heat exchanger and each of the plurality of accessory heat exchangers flow is controllable using a modulating valve.

1. A thermal management system (TMS) comprising:
an engine heat exchanger comprising an engine liquid system of a propulsive engine of a vehicle, said engine liquid system configured to channel a flow of lube oil therethrough that recovers waste heat conducted from engine accessories of the vehicle, wherein said engine heat exchanger facilitates transferring the waste heat from the lube oil to a pumped heat transfer fluid channeled through said engine heat exchanger; an engine exhaust heat exchanger coupled in serial flow communication with said engine heat exchanger, said engine exhaust heat exchanger configured to transfer heat from an exhaust stream of the propulsive engine to the pumped heat transfer fluid; a bypass valve coupled in parallel with said engine exhaust heat exchanger, said bypass valve selectable to modulate a flow of the pumped heat transfer fluid through the engine exhaust heat exchanger; and a plurality of accessory heat exchangers for each of a plurality of heat loads of the vehicle coupled in flow communication with at least one of said engine heat exchanger and said engine exhaust heat exchanger, each said plurality of accessory heat exchangers flow controllable using a modulating valve.
