Abstract: A heat exchanger and a method for manufacturing the same provides a double pipe heat exchanger including an outer pipe, an inner pipe forming a first fluid passage and a second fluid passage between the inner pipe and the outer pipe, first and second connecting pipes to pass fluid from the outside and exhaust the fluid by connecting ends of the outer pipe, and a connector to connect the inner pipe and each connecting pipe to the outer pipe. The connector includes expanded ends of the outer pipe and a reducing part configured to assemble the inner pipe inserted in the outer pipe with an end of each connecting pipe by forming at an end of each expanding part with a pressing process. The center line of the inner pipe connected to the connector is disposed at an upper side of the inner circumference surface of the outer pipe.

Abstract: A double pipe heat exchanger and a method of manufacturing the same are provided. The double pipe heat exchanger including an outer pipe and an inner pipe having a first flow channel therein and having an outer diameter smaller than an inner diameter of the outer pipe and inserted into the outer pipe to form a second flow channel between the inner pipe and the outer pipe includes a plurality of first grooves formed in a spiral shape in a lengthwise direction at an outer circumferential surface of the inner pipe to enable the second flow channel to have at least partially a spiral shape and at least one second groove each formed in a portion between two first grooves adjacent to an outer circumferential surface of the inner pipe and formed along the first groove.

Abstract: A notification system of a vehicle includes a sensing unit that detects an object outside the vehicle or detects an operational status of a function of the vehicle; an output unit; and a controller. The controller is configured to determine whether a touch has been detected on an interior handle of a door of the vehicle. If a touch is detected on the interior handle, the controller determines that an object outside the vehicle detected by the sensor is within a predetermined distance in a rearward direction from the door on which the touch was detected, or determines that an operational status of a function of the vehicle detected by the sensor indicates that the function is not yet complete; and controls the output unit to output a notification corresponding to the detected object outside the vehicle or the detected operational status of the function of the vehicle.

Abstract: A method for operating an image display apparatus using a remote controller includes receiving a signal from the remote controller, calculating display coordinates for pointer display based on the received signal; displaying a first pointer at the calculated display coordinates if the calculated display coordinates are within boundaries of a display screen, and displaying a second pointer at the boundaries of the display screen if the calculated display coordinates move off of the boundaries of the display screen. Accordingly, it is possible to increase movement accuracy and efficiency of the remote controller and increase user convenience.
