  • Patent number: 11606006
    Abstract: A system for overcooling a drive motor and a method for controlling the same may include a first cooling loop in which a first coolant circulate, the first coolant being in a heat exchange with a power electronics (PE) part and a drive motor cooler mounted in the first cooling line and configured to cool cooling oil supplied to the drive motor fluidically connected to the drive motor cooler; a second cooling loop disposed independently from the first cooling loop, wherein a second coolant circulates in the second cooling loop, the second coolant being in a heat exchange with a battery module and a battery chiller mounted in the second cooling loop; and a switch unit configured to selectively shift a flow path of the second coolant such that the second coolant is in a heat exchange with the drive motor cooler.

  • Patent number: 11280230
    Abstract: An electric oil pump system integrated with a heat exchanger capable of reducing installation space and cost may include: an the electric oil pump including a motor and a pumping part operated by power of the motor to suck and send oil under pressurizing to an oil-used part; and a heat exchanger to exchange heat between the pressurized oil sent by the electric oil pump and coolant cooled at a radiator while the coolant and the pressurized oil pass through the heat exchanger. In particular, the heat exchanger is directly coupled to the electric oil pump and the oil-used part, respectively, and integrated with each other.

  • Patent number: 10556499
    Abstract: An apparatus for cooling a motor of a hybrid vehicle includes a support ring that is disposed between a motor casing and a motor and has a shape that encloses the motor. A water jacket is formed in the support ring and circulates cooling water and an oil jacket is formed in a support ring and circulates oil. Further, oil is discharged from the oil jacket is sprayed onto the motor to enable the oil to be used to cool the motor and to enable cooling water to be used to cool the motor. Accordingly, the performance of cooling the motor is enhanced.

  • Patent number: 6078314
    Abstract: An apparatus and a method for retrieving information in a mobile information terminal are provided. The device includes a display, a position detector and a controller. The display displays a data display area for showing information depending on retrieval commands and a button area which is always displayed in a restricted size at a predetermined position and includes a plurality of buttons for inputting at least one command for creating a connection with the host for retrieval, a command for transferring to a retrieval area, and a command for selecting of an item to be searched. The position detector detects positional data corresponding to a button pressed by a user. The controller searches information from the host according to a command corresponding to the positional data detected by the position detector, and allows the searched information to be displayed on the data display area of the display. Accordingly, use of a keyboard can be minimized by installing essential commands in the form of buttons.
