Patent number: 6988541Abstract: An oil cooler is held by holding plates. Top portions of side pieces of each holding plate are disposed through a side wall of a tank and are bent at the outer surface of the tank, so that circular interposed members and the oil cooler are retained by being sandwiched between middle supporter pieces of the holding plates and the side wall of the tank in the stacking direction of element units such that the oil cooler is movable in the longitudinal direction with respect to the side wall of the tank. By inserting connecting pipes of the oil cooler through openings of the tank so as to temporarily assemble the connecting pipes into openings of a tube plate, blocking flanges of the connecting pipes are retained while being in contact with the outer surface of the side wall of the tank.Type: GrantFiled: December 7, 2004Date of Patent: January 24, 2006Assignee: Calsonic Kansei CorporationInventors: Shiro Nakajima, Satoshi Kimura, Kenji Tochigi, Hiroyuki Okura, Shinichi Miyasaka

Patent number: 6968891Abstract: A virtual quadrangle having vertexes respectively configured by: inner ends which are located respectively at a corner of inner cut end faces of the louvers formed in flat portions that are opposed to each other across the bent portion; and outer ends which are located respectively at a corner of outer cut end faces of the louvers, is assumed. A distortion adjusting portion is disposed in the bent portion of the louver fin. The distortion adjusting portion equalizes distortion generated in the direction of an inner diagonal line connecting the inner ends of the virtual quadrangle, with that generated in the direction of an outer diagonal line connecting the outer ends of the virtual quadrangle. Thereby, the louver fin can be prevented from being curved in the longitudinal direction.Type: GrantFiled: March 7, 2003Date of Patent: November 29, 2005Assignee: Calsonic Kansei CorporationInventors: Kenji Tochigi, Hirokazu Yaezawa, Takahiro Nakakomi
