  • Patent number: 11078936
    Abstract: An external cooling system for hydraulic fluid of an aircraft hydraulic system. The external cooling system includes a heat exchanger, where an input side of the heat exchanger is connected to a hydraulic fluid reservoir of the aircraft hydraulic system and an output side of the heat exchanger is connected to suction ports of a return side of an electric motor driven pump (EMDP) of the aircraft hydraulic system. The external cooling system operates on 120 VAC power and the hydraulic fluid does not exceed a maximum pressure of 50 pounds per square inch gauge. The EMDP pumps hydraulic fluid through the hydraulic system under conditions wherein fuel tanks in the aircraft are empty, and the external cooling system cools the hydraulic fluid as the EMDP pumps the hydraulic fluid, wherein the hydraulic fluid passes from the hydraulic fluid reservoir and through the external cooling system before entering the EMDP.

  • Patent number: 10982907
    Abstract: A heat pipe includes one or more reservoirs of liquid that are closed at lower temperatures and open at higher temperatures. The opening of the reservoirs at higher temperatures caused by higher power levels dynamically increases the amount of liquid in the heat pipe, which increases performance of the heat pipe at higher power levels. As the heat pipe cools, the liquid condenses and flows back into the reservoirs. As the heat pipe continues to cool, the reservoirs close. The result is a heat pipe that is more efficient at lower power levels and still maintains high efficiency at higher power levels due to the demand-based charging of the liquid based on temperature.

  • Patent number: 10967750
    Abstract: A system and method for charging a plug-in hybrid vehicle can improve the on-board charging efficiency of the plug-in hybrid vehicle by adjusting a frequency of operation of a cooler when cooling an on-board charger (OBC) by circulating coolant when the temperature of the OBC rises while a high-voltage battery is being charged. The operations of a water pump and a radiator fan are controlled by determining whether the voltage of the high-voltage battery is within or out of a reference voltage range in which the on-board charging of the high-voltage battery is performed. This consequently prevents power from being unnecessarily consumed by operation of the cooler, such that the efficiency of charging is improved and the OBC is properly cooled.

  • Patent number: 10955151
    Abstract: A system and method for estimating the state of charge, i.e., the amount of cooling remaining, in a latent heat thermal storage module of a local environmental control system. The local environmental control system stores cooling energy at night by freezing a latent heat phase change material (PCM), and then releasing the stored cooling energy by removing heat from room air flowing through the PCM during the day. Differential temperature sensors are used measure the air temperature drop across the latent thermals storage unit and the fan voltage, which is directly related to fan air flow rate, is sampled. A controller is programmed to determine the charging state from these measurements.
