Three Non-communicating Fluids Patents (Class 165/140)
  • Patent number: 8886374
    Abstract: The present invention provides a torque control method for an HEV, the method comprising: detecting an operation failure of an integrated starter-generator (ISG); calculating a driver demand torque based on a current accelerator position sensor (APS); controlling the hydraulic pressure and operation of a clutch so as to increase an engine speed to convert the driving mode of the vehicle from electric vehicle (EV) mode to hybrid electric vehicle (HEV) mode in the event that an operation failure of the ISG is detected and the driver demand torque is out of a predetermined range; and compensating the driver demand torque to a desired level based on a transfer torque from the clutch to a motor. The method can improve driving performance and power performance of HEV, in the event of ISG failure, by performing a hydraulic control for a clutch and calculating a driver request torque and a transfer torque from the clutch to a motor to compensate the drive request torque to a desired level.

  • Publication number: 20140318749
    Abstract: In a heat exchanger, a second fluid flowing space communicating with second tubes is formed to be divided from a first tank space within a tank unit forming a first tank space that collects or distributes a refrigerant. The tank unit is defrosted by a coolant flowing in the second fluid flowing space, which is higher in temperature than the refrigerant flowing in the first tank space. With this configuration, heat from the second fluid flowing in the second fluid flowing space included in the tank unit is effectively transferred to a portion of the tank unit which is likely to be frosted.

  • Patent number: 8186424
    Abstract: A charge air cooler comprises at least one tubular element with an internal flow duct for guiding compressed air, and a tank for receiving the compressed air before it is led through the flow duct. The compressed air is cooled by a first cooling medium of ambient air as it passes through the flow duct. A cooling element at least partly situated inside the tank provides the compressed air in the tank with a first step of cooling before the air is led to the flow duct wherein the air undergoes a second step of cooling.

  • Patent number: 8096347
    Abstract: A cooler block for an agricultural tractor comprising a cooler assembly mounted on a radiator and coupled to the radiator by upper and lower linkages. The cooler assembly can be moved between a first position in which the cooler assembly lies parallel to the radiator and a second position in which the cooler assembly is inclined relative to the radiator. The cooler assembly is pivotable about a pivot in the upper linkage that is itself movable relative to the radiator. The lower linkage allows the entire cooler assembly to rise and the pivot of the upper linkage to move away from the radiator as the cooler assembly is pivoted from the first to the second position. A detent is incorporated into one of the two linkages to retain the cooler assembly in the second position.

  • Patent number: 8079407
    Abstract: An integrated heat exchanger comprises a primary heat transfer zone and a secondary heat transfer zone integral to the primary heat transfer zone. The primary heat transfer zone comprises an ECS heat exchanger and the secondary heat transfer zone comprises a heat exchanger for a secondary system, such as an OBIGGS heat exchanger. The integrated heat exchanger reduces the negative impact that the OBIGGS heat exchanger has on the ECS heat exchanger by providing one ram face, thereby minimizing the flow disturbances associated with the OBIGGS heat exchanger. By integrating the OBIGGS and the ECS heat exchanger, the integrated heat exchanger reduces the negative impact of the pressure drop and heat load caused by the OBIGGS heat exchanger.

  • Patent number: 8051906
    Abstract: The assembly includes a pair of heat exchangers, each including an upper and lower manifold, parallel and spaced relative to one another. Tubes extend between each set of upper and lower manifolds with fins disposed between each of the tubes. A valve system controls fluid flow between the upper manifolds and the lower manifolds. The valve system is movable between a maximum cooling mode with fluid flow form the first upper manifold through both of the tubes and to said first lower manifold. A temperate mode allows fluid to flow from the first upper manifold to the first lower manifold and from the second upper manifold to the second lower manifold to prevent flash fogging. A maximum cooling mode allows fluid to flow from the second upper manifold through both of the first and second tubes to the lower manifolds.

  • Patent number: 8034308
    Abstract: A multi-stage, multi-tube, shell-and-tube reactor which contains reaction zones and interstage temperature control (cooling/heating) zones in series. The reactor has at least two types of zones which both contribute to removing or supplying heat to the system depending on the system's need. The reactor will have a group of reaction zones which contain tubes packed with catalyst to progress the reaction and remove or supply heat simultaneously. There are also a number of interstage temperature control (cooling/heating) zones which are designed to supply or remove heat to or from the system. The positioning, number, and design of the zones will depend on the amount of temperature control desired and exothermic or endothermic nature of the processes to be conducted in the reactor.
