| 20120061069 | Cooling In A Liquid-To-Air Heat Exchanger - In an engine coolant circuit with a radiator and an engine, a fan and a coolant pump may be provided. The fan and pump may be electrically driven, driven by a variable speed clutch, hydraulically driven, or driven by some other actively controllable means. When an increase in heat transfer rate is indicated, the fan speed or the coolant pump speed may be increased. According to an embodiment of the disclosure, the choice of increasing the fan speed or increasing the pump speed is determined so that the power consumed is minimized. The broad concept is that dQ/dP, the gradient in heat transfer rate to power, is determined for both the fan and the pump at the present operating condition. The one with the higher gradient is the one that is commanded to increase speed. | 03-15-2012 |
| 20120132411 | WIND POWER GENERATING SYSTEM FOR VEHICLE USING MOTOR FOR COOLING FAN - Provided is a wind power generating system for a vehicle using a cooling fan motor that is operated by receiving power from a battery, the system including a cooling fan motor operated in a cooling mode to cool a heat exchanger with the applied power or operated in a power generation mode to produce electricity by rotating a cooling fan by driving wind, and a control device controlling rotation of the cooling fan motor and determining whether the cooling fan motor is operated in the power generation mode or the cooling mode. | 05-31-2012 |
| 20120168140 | Cooling System for Electric Vehicle - A cooling system for an electric vehicle includes: a cooling unit that cools an electric drive unit; and a control unit that controls cooling of the electric drive unit by controlling the cooling unit. The control unit controls the cooling unit in a first cooling mode that provides a first cooling capacity when a force for driving the electric vehicle due to the electric drive unit is in a first operational region, and controls the cooling unit in a second cooling mode that provides a second cooling capacity that is higher than the first cooling capacity when the force due to the electric drive unit is in a second operational region that is higher than the first operational region; and in the second cooling mode, the control unit controls the cooling unit so that the second cooling capacity becomes higher as a rotational speed of the electric drive unit decreases. | 07-05-2012 |
| 20120211216 | SYSTEM AND METHOD FOR CONTROLLING A TEMPERATURE OF OIL IN A POWER-PLANT OF A VEHICLE - A system is provided for controlling a temperature of oil in a power-plant operable to propel a vehicle. The system includes a heat-exchanger arranged relative to the power-plant. The heat-exchanger is configured to receive the oil from the power-plant, modify the temperature of the oil, and return the modified temperature oil to the power-plant. The system also includes a valve configured to direct the oil through the heat-exchanger during a warm-up operation of the power-plant such that the temperature of the oil is increased. The valve is also configured to direct the oil to bypass the heat-exchanger during a low load operation of the power-plant such that the temperature of the oil is increased. Additionally, the valve is configured to direct the oil through the heat-exchanger during a high load operation of the power-plant such that the temperature of the oil is decreased. | 08-23-2012 |
| 20130153198 | FLUID SYSTEM AND METHOD OF CONTROLLING FLUID FLOW FOR AN INTERCOOLER - A fluid system for an intercooler has a fill level defining a maximum volume of liquid in the fluid system, a main fluid circuit and a secondary fluid volume. The main fluid circuit includes the intercooler, and one or more passages through which fluid is circulated with operation of the engine, and at least a portion of the main fluid circuit is located above the fill level. The secondary fluid volume has at least a portion located below the fill level that communicates with the main fluid circuit to receive liquid from the main fluid circuit at least when the engine is not operating to drain at least some of the liquid from the portion of the main fluid circuit that is located above the fill level. This reduces the volume of liquid that remains above the fill level when the engine is not operating. | 06-20-2013 |
| 20130248165 | POWER REGULATION SYSTEM FOR A MOBILE ENVIRONMENT-CONTROLLED UNIT AND METHOD OF CONTROLLING THE SAME - A mobile environment-controlled unit comprising a chassis, a compartment supported by the chassis, and an environmental-control system in environmental communication with the compartment. The environmental-control system is configured to control an environmental parameter of the compartment. The environmental-control system includes an AC Alternator and a controller. The AC alternator is powered by an internal combustion engine and supplies electrical power for the environmental-control system. The controller is configured to monitor the environmental parameter of the compartment, monitor one or more electrical parameters of the AC alternator, control the environmental-control system based on the monitored environmental parameter, and control the AC alternator based on the monitored parameters of the alternator. | 09-26-2013 |
| 20140318759 | METHOD OF CONTROLLING A COOLING SYSTEM - A method of controlling an aircraft gas turbine engine cooling system. The cooling system includes a heat exchanger having a first fluid path through which fan air flows, and a second fluid path through which relatively hot compressor air flows. The cooling system includes a valve configurable between an open position corresponding to a first operating mode, where fan air flows through the first path cooling the compressor air in the second path to a lower temperature, and a closed position corresponding to a second operating mode, where fan air may flow through the first path at a reduced rate, thus the compressor air in the second path could be cooled to a lesser extent. The valve is operated in first mode when the aircraft is in a descent mode, or when turbine entry temperature is above a predetermined amount. Otherwise, the valve is operated in second mode. | 10-30-2014 |
| 20160068042 | VEHICLE CLIMATE CONTROL METHOD - A method for controlling a climate control system is disclosed. In one example, the climate control system includes an air mixing valve that is adjusted in response to a energy conversion device load demand. The method may provide improved climate control in a vehicle cabin during high energy conversion device load conditions. | 03-10-2016 |
