Patent number: 11780034Abstract: A brazing sheet (1) includes a core material (11) composed of an Al alloy that contains 0.20-3.0 mass % of Mg; and a filler material (12) layered on the core material and composed of an Al alloy that contains Mg, 6.0-13.0 mass % of Si, and more than 0.050 mass % and 1.0 mass % or less of Bi. The Mg concentration of the filler material becomes continuously lower in a direction from a boundary (122) with the core material to an outermost surface (121). The Mg concentration of the filler material is 0.150 mass % or less at a first depth from the outermost surface that is ? of a thickness (tf) of the filler material and is 5-90% of the amount of Mg in the core material at a second depth from the outermost surface that is ? of the thickness of the filler material.Type: GrantFiled: September 27, 2019Date of Patent: October 10, 2023Assignees: UACJ CORPORATION, DENSO CORPORATIONInventors: Shinichi Nakamura, Tomoki Yamayoshi, Takeyoshi Dokou, Takahiro Shinoda, Shogo Yamada, Yoshihiko Sonoda, Naoki Sugimoto, Nobuhiro Honma, Taketoshi Toyama

Patent number: 7413002Abstract: In a corrugated fin which is formed and bent into a wave-form, a plurality of both-side-cut-louvers 8, which are laminated on each other and formed into a group, and one-side-cut-louvers 7, which are arranged at end portions of the group of both-side-cut-louvers 8, are formed being raised, and a cross-section in the louver laminating direction of at least one of the one-side-cut-louvers 7 is formed into a substantial V-shape. An inclined face 70 of the one-side-cut-louver 7 adjoining the both-side-cut-louver 8 is made to cross a centerline in the fin thickness direction and a length of the inclined face 70 is made to be the same as that of the inclined face of the adjoining both-side-cut-louver 8.Type: GrantFiled: December 14, 2006Date of Patent: August 19, 2008Assignee: Denso CorporationInventors: Toshihide Ninagawa, Yuuji Sako, Yoshihiko Sonoda

Patent number: 7310961Abstract: A heat exchange portion is configured by arranging a condenser for air conditioning, an EV radiator, and a FC radiator in one plane substantially perpendicular to a direction in which a fuel cell vehicle moves, at a front portion of the fuel cell vehicle, in order of an operating temperature, from an upper position to a lower position. A fan is provided behind the heat exchange portion such that a center thereof is closer to the condenser than to the FC radiator. In addition, a fan shroud is provided, in which plural ram pressure holes are formed in a portion which covers the FC radiator.Type: GrantFiled: June 13, 2005Date of Patent: December 25, 2007Assignee: Toyota Jidosha Kabushiki KaishaInventors: Jun Hoshi, Minobu Mizuno, Mitsuru Kimata, Susumu Ichikawa, Keiichi Yoshii, Akira Yamanaka, Yoshihiko Sonoda, Hiroshi Nonoyama

Publication number: 20070187080Abstract: A heat exchanger has a tank and a core including a plurality of tubes stacked in a longitudinal direction of the tank and in communication with the tank. The heat exchanger further has an inlet port for introducing a fluid into the tank and a first projection on an inner wall of the tank at a position where the fluid flowing from the inlet port hits on. The first projection is configured to change a flow direction of the fluid flowing from the inlet port in the longitudinal direction of the tank. For example, the first projection projects from the inner wall of the tank toward the inlet port in a form of substantially wedge.Type: ApplicationFiled: February 9, 2007Publication date: August 16, 2007Applicant: DENSO CorporationInventors: Yoshihiko Sonoda, Toshihide Ninagawa, Tatsuo Ozaki

Publication number: 20050236147Abstract: A heat exchanger for cooling a fuel cell is provided with multiple fins, multiple tubes which are laminated and separated from each other by the fin, and at least two tanks which are communicated with the tubes at longitudinal-direction ends of the tubes. Cooling water is circulated to flow through the tubes, the tanks and the fuel cell. The tanks and the tubes are made of resin, while the fins are made of metal. Thus, cooling water which carries electricity can be electrically insulated from the externals by the tanks and the tubes, while the cooling capacity of the heat exchanger can be satisfactorily maintained.Type: ApplicationFiled: April 19, 2005Publication date: October 27, 2005Applicant: DENSO CorporationInventors: Yoshihiko Sonoda, Takaki Okochi

Publication number: 20040244954Abstract: A heat exchanger includes plural laminated tubes through which a coolant from a fuel cell flows, fins arranged between the tubes and at outermost sides in a lamination direction of the tubes, core plates connected to longitudinal end portions of the tubes, and tank members attached to the core plates to form tank spaces. The tubes are made of a first insulating material, and the fins and the core plates are bonded to the tubes by using metal parts provided separately from each other on surfaces of the tubes. In addition, a coating portion is coated with a second insulating material on surfaces of the core plates at least at an exposed position of the core plates and at positions around brazing portions of the core plate bonded to the tubes. Accordingly, the heat exchanger can be insulated from the fuel cell without using an electrical insulating liquid.Type: ApplicationFiled: June 2, 2004Publication date: December 9, 2004Inventors: Tetsuya Goto, Takaki Okochi, Yoshihiko Sonoda, Atsushi Hayasaka

Patent number: 5312230Abstract: An axial flow fan device capable of reducing the stagnant flow at the root area of blades. These blades 18 are arranged so that they extend radially from a boss portion 14 so that they are circumferentially spaced along the circumference of the boss portion 14. Each of the blades 18 has an arc shaped cross section having a bending ratio value .alpha., that is a ratio of the bending height h of the arc shape to the length l of the chord of the arc shape. The value of the bending ratio rapidly increases from the middle portion of the blade to the root portion. The value of the bending ratio at the root portion is about 12%.Type: GrantFiled: December 16, 1992Date of Patent: May 17, 1994Assignee: Nippondenso Co., Ltd.Inventors: Siniti Oda, Shuji Komoda, Yoshihiko Sonoda
