Publication number: 20240092141Abstract: An air conditioning device for a vehicle includes: a housing having an inside divided into an inflow space, a heat exchange space, and an outflow space, which are straightly arranged, and having a plurality of discharge ports, which communicates with an interior, at the inflow space; a blowing unit disposed at the inflow space of the housing and configured to blow air; a heat exchange unit disposed at the heat exchange space of the housing and configured to adjust a temperature of conditioned air by exchanging heat with air; and an opening-closing door disposed at the outflow space of the housing and configured to open and close the plurality of discharge ports such that conditioned air at an adjusted temperature selectively flows to the plurality of discharge ports. The air conditioning device adjusts the temperature of conditioned air for respective modes and reduces a flow resistance of air.Type: ApplicationFiled: March 8, 2023Publication date: March 21, 2024Applicants: HYUNDAI MOTOR COMPANY, KIA CORPORATION, DOOWON CLIMATE CONTROL CO., LTD.Inventors: Kwang Ok Han, Young Tae Song, Yong Chul Kim, Gee Young Shin, Su Yeon Kang, Jae Sik Choi, Dae Hee Lee, Byeong Moo Jang, Ung Hwi Kim, Jae Won Cha, Won Jun Joung, Byung Guk An

Patent number: 8026787Abstract: A ceramic component element is provided. The ceramic component element includes: an insulating ceramic base with pores formed on its surface and previously fired; and a functional ceramic sheet bonded to the insulating ceramic base and having electrical characteristics. The functional ceramic sheet is physically bonded to the insulating ceramic base by forming pressing a green sheet for the functional ceramic sheet on the insulating ceramic base at constant temperature and pressure so that parts of the green sheet are forced to put into the pores and anchored, and the functional ceramic sheet is chemically bonded to the insulating ceramic base by firing the anchored green sheet in such a manner that functional oxides of the green sheet penetrate the insulating ceramic base by solid diffusion to form a diffusion bonding layer.Type: GrantFiled: February 15, 2007Date of Patent: September 27, 2011Assignee: Joinset Co., Ltd.Inventors: Kwang-Hwi Choi, Seong-Soo Jo, Sun-Ki Kim

Patent number: 7791450Abstract: Provided are a ceramic component and a method of manufacturing the ceramic component. The ceramic component includes a previously fired insulation ceramic base, a functional ceramic sheet bonded to the insulation ceramic base by a diffusion bonding layer having an anchoring structure, internal electrodes embedded into the functional ceramic sheet, and external electrodes connected to the internal electrodes. A functional ceramic paste corresponding to the functional ceramic sheet is applied to the insulation ceramic base and is dried to form a functional ceramic film. The functional ceramic film is pressed against the insulation ceramic base to anchor functional ceramic film into the insulation ceramic base for sure attachment. The functional ceramic film is fired to allow functional oxide materials included in the functional ceramic film to permeate the insulation ceramic base by solid diffusion to form the diffusion bonding layer and to change the functional ceramic film into the functional ceramic sheet.Type: GrantFiled: December 30, 2008Date of Patent: September 7, 2010Assignee: Joinset Co., Ltd.Inventors: Kwang-Hwi Choi, Seong-Soo Jo, Sun-Ki Kim
