Abstract: An ultra-efficient turbo-compression cooling system links an organic Rankine power cycle and a vapor compression cooling cycle using a turbine and compressor that shares a single shaft and further linked to an evaporative condenser. The power cycle implements a waste heat exchanger configured to evaporate a working fluid and a turbine configured to receive the evaporated working fluid. The turbine has a plurality of vanes disposed around a central shaft and configured to rotate as the working fluid expands to a lower pressure within the turbine. An evaporative condenser then condenses the working fluid to a saturated liquid and a mechanical pump pumps the saturated liquid to reenter the waste heat waste heat exchanger. The cooling cycle implements a compressor configured to increase the pressure of the working fluid, with the evaporative condenser (shared with the power cycle) configured to condense the working fluid to a saturated liquid upon exiting the compressor, an expansion valve wherein the working fluid expands to a lower pressure, and an evaporator rejecting heat from a circulating fluid to the working fluid, thereby cooling the circulating fluid.

Abstract: The high thermal conduction resistances of a lithium-ion battery (LIB) severely limit the effectiveness of a conventional external thermal management system (TMS). A method for a new thermal management system for lithium-ion batteries that utilizes a multi-functional electrolyte (MFE) to remove heat locally inside the cell by evaporating a volatile component of the MFE is disclosed. These new electrolyte mixtures comprise a high vapor pressure co-solvent. The characteristics of a previously unstudied high vapor pressure co-solvent HFE-7000 (65 kPa at 25° C.) in an MFE (1 M LiTFSI in 1:1 HFE-7000/EMC), and other possible MFE compositions that can be utilized in a custom electrolyte boiling facility, are disclosed.

Abstract: The present disclosure relates to a laser diode system. The system may have at least one laser diode emitter having a substrate, at least one laser diode supported on the substrate, and a facet which a laser beam generated by the laser diode is emitted. A cooling subsystem is included which is disposed in contact with the substrate of the laser diode emitter. The cooling subsystem includes a plurality of cooling fins forming a plurality of elongated channels for circulating a cooling fluid therethrough to cool the laser diode emitter. The cooling fluid also flows over the facet of the laser diode emitter.
