Abstract: Disclosed is an aroma-diffusing cartridge for a vehicle wherein the structures of the cartridge and a carrier of an aroma are so optimized that the capacity of the carrier for carrying the aroma may become excellent together with stable and continuous performance of diffusing the aroma. An aroma-diffusing cartridge for a vehicle includes: a cartridge body having one side formed with a pair of air holes for receiving and discharging air, and an internal space for circulating the received air; and at least two carriers put in the cartridge body with different duration of keeping an aroma. Thus, the capacity of the carriers for carrying an aroma is excellent together with stable and continuous performance of diffusing the aroma in a limited space, so that the air in the vehicle may be kept agreeable for a long time.

Abstract: An auxiliary cooling and heating apparatus for automobiles using a thermoelectric module, in which a thermoelectric module is divided into plural ones and supplied with electric power sequentially to reduce inrush current of the thermoelectric module, thereby reducing a load of an electric system of the automobile and increasing durability of the electric system, and enhancing efficiency of the thermoelectric module by controlling capacity in the optimum state.

Abstract: The present invention relates to an air conditioner for vehicles, and more particularly, to an air conditioner for vehicles, in which a seat vent is formed on an air-conditioning case to supply some of air existing in a mixing area formed inside the air-conditioning case to the seat and a heat exchanger for seat is also mounted in the air-conditioning case, thereby securing an installation space for installing convenient devices inside a seat, and in which the air conditioner is utilized to cool and heat the seat, thereby reducing consumption of energy by enhancing efficiency, decreasing the number of components since additional temperature-adjusting door is not needed, and supplying a fixed amount of air to the seat regardless of air-conditioning modes.

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.
