Abstract

A system for controlling fluid temperature in a thermal system includes a heat source, a heat sink coupled to the heat source, a first heat exchanger and a second heat exchanger, a first expansion valve configured to regulate the flow of coolant between the heat source and the first heat exchanger, a second expansion valve configured to regulate the flow of coolant between the heat source and the second heat exchanger, and a controller. The controller is configured to determine an operating condition of the thermal system and generate a first control signal to control the first and second expansion valves to direct the flow of coolant to the first and second heat exchangers. The first and second expansion valves are arranged in parallel to recover heat rejected from the coolant and distribute the recovered heat to the first and second heat exchangers.

Description

technical field [0001] The present disclosure generally relates to systems and methods for controlling the temperature of a fluid in a thermal system, particularly using two-phase heat transfer for heat dissipation from an engine. Background technique [0002] Efficient operation of a powertrain depends on various factors, including operating conditions and load demands. Heating and / or cooling engine oil and / or transmission oil via heat exchangers and heat sinks provides some measure of temperature control. However, many systems include multiple pathways and components, which increase system complexity and create packaging constraints. Contents of the invention [0003] Embodiments according to the present disclosure provide several advantages. For example, embodiments according to the present disclosure use a two-phase heat transfer compatible coolant, such as refrigerant, to allow for increased operating temperatures of the engine and energy distribution to other compo...
