  • Patent number: 11007850
    Abstract: A heat pump system for a vehicle cools or warms a battery module by use of one chiller in which a coolant and a refrigerant exchange heat such that the system may be simplified, and heating efficiency may be improved by selectively using an external air heat source and waste heat of an electrical component in a heating mode of the vehicle.
    Type: Grant
    Filed: October 30, 2019
    Date of Patent: May 18, 2021
    Assignees: Hyundai Motor Gompany, Kia Motors Corporation, Hanon Systems

  • Patent number: 8074709
    Abstract: The present invention relates to a center mounting type air conditioner for a vehicle, which can reduce size and noise of a blower, and enhance installation efficiency and reduce an installation space of the air conditioner installed in the vehicle. At least one bypass passageway is formed in a dead space located between the scroll case and the air conditioning case, whereby some of air sucked from the intake duct is bypassed and sucked toward the second wheel of the dual blower wheel, to which the motor is connected.

  • Patent number: 7413003
    Abstract: The present invention relates to a plate for a heat exchanger, which has beads of refrigerant distributing sections formed asymmetrically and streamlined beads arranged in the same number on flow channels in the form of a zigzag so that refrigerant flowing inside a tank is distributed and introduced to tubes uniformly, thereby increasing a heat radiation amount and enhancing a heat exchange efficiency by forming uniform flow distribution and reducing a pressure drop of refrigerant, and miniaturizing the heat exchanger into a compact size.

  • Patent number: 6929059
    Abstract: An aluminum radiator includes a core including a plurality of tubes through which a heat exchange medium flows and fins arranged between the tubes; and a header tank including a pair of header spaced apart from each other and having both ends coupled to the tube, a tank coupled to the header by a brazing and having a heat exchange medium passage formed therein, and end caps coupled to both opening portions of the tank, wherein the tube satisfies an inequality 10 mm?T?20 mm, where T denotes an outside width of the tube, and the tank has an inside height (H) of 41 mm or less and satisfies an inequality 1.5?H/T?2.5.
