Patent number: 9583800Abstract: The invention relates to a vehicle, having a cooling air duct disposed within a battery to move cooling air for cooling the battery, so as to enable same to be compact and improve space utilization, in order to optimize cooling performance within a limited space. The vehicle of the present invention also includes a battery-cooling unit that exchanges heat and cools air ventilated from the passenger compartment and then supplies the air to the battery, so as to use the air from the passenger compartment with minimal effects on the air temperature in the passenger compartment, and more efficiently cool the battery. Further, the vehicle and method for controlling same according to the present invention can detect the temperatures of the battery and of the passenger compartment, and determine whether to cool the air in the passenger compartment using a heat exchanger in accordance with each detected temperature, or control the rotation speed of a ventilation fan, in order to more efficiently cool the battery.Type: GrantFiled: March 3, 2011Date of Patent: February 28, 2017Assignee: LG ELECTRONICS INC.Inventors: Jae Cheol Hwang, Hyun Woo Yoon, Tae Jin Kim

Patent number: 9531041Abstract: According to the present invention, a battery-cooling system for an electric vehicle is configured such that the cool air cooled by an air-conditioning device is directly supplied to a battery without passing through the interior of a vehicle, thus enabling the interior of the vehicle and the battery to be cooled independently from each other, thereby not only preventing noise or foreign substances from entering the battery from the interior of the vehicle, but also controlling a vehicle interior cooling operation and a battery cooling operation independently from each other. Further, a battery-cooling system for an electric vehicle according to the present invention is configured such that a suction fan is arranged at a discharge duct for discharging air from the interior of a battery, thus enabling air in the interior of the battery to be suctioned and discharged by the suction fan.Type: GrantFiled: December 14, 2012Date of Patent: December 27, 2016Assignee: LG ELECTRONICS INC.Inventor: Jae Cheol Hwang

Publication number: 20080143472Abstract: A fuse structure of a semiconductor device includes a fuse pattern having a contact portions at opposite ends of the fuse pattern, wherein the fuse pattern includes a first conductive layer and a second conductive layer stacked sequentially, and a first electrode and a second electrode connected to the contact portions respectively. The fuse pattern is configured to be electrically shorted during a fuse program operation. A bottleneck portion can be formed at the center of the fuse pattern spaced apart from pad portions formed at opposite ends of the fuse pattern to which an electrode is connected, enabling breakage of the fuse pattern to be spaced apart from a contact portion of the electrode. As a result, a profile of a portion broken after a fuse program operation is improved and leakage current caused by a poor profile is suppressed.Type: ApplicationFiled: December 13, 2007Publication date: June 19, 2008Applicant: Samsung Electronics Co., Ltd.Inventors: Ghil-Geun Oh, Jae-Hyun Ryu, Jae-Cheol Hwang
