Patent number: 10386132Abstract: A forward-tilting protruding piece leans forward toward an upstream side in a gas flow direction. A rearward-tilting protruding piece is disposed downstream of the forward-tilting protruding piece and leans rearward toward a downstream side in the gas flow direction. The forward-tilting protruding piece is in a shape of a four- or more-sided polygon including a base side in contact with a peripheral surface of the gas passage and a pair of left and right sides. The base side is oriented obliquely with respect to a direction perpendicular to the gas flow direction. The angle of one of the sides which is located on the upstream side in the gas flow direction with respect to the base side is larger than the angle of the other of the sides which is located on the downstream side in the gas flow direction with respect to the base side.Type: GrantFiled: April 17, 2014Date of Patent: August 20, 2019Assignee: CALSONIC KANSEI CORPORATIONInventors: Mitsuru Iwasaki, Junichiro Hara

Patent number: 10357944Abstract: An aluminum alloy substrate bears a first layer on at least one side thereof, and a second layer on at least part of the first layer. The first layer includes an oxide film containing Mg in a content of from 0.1 atomic percent to less than 30 atomic percent. The second layer contains siloxane bonds. The second layer is disposed in a mass of coating of from 0.1 mg/m2 to less than 30 mg/m2. Assume that parallel polarized light is applied to the side bearing the first layer and the second layer at an incident angle of 75°, and resulting data are analyzed by Fourier-transform infrared spectroscopy to give a spectrum. In the spectrum, a peak occurring adjacent to 1057 cm?1 has an area of 0.01 or more with respect to a base line drawn from 1026 cm?1 to 1084 cm?1.Type: GrantFiled: May 21, 2014Date of Patent: July 23, 2019Assignee: Kobe Steel, Ltd.Inventors: Satoru Takada, Akihiko Tatsumi

Patent number: 10309729Abstract: A corrugated fin heat exchanger is provided in which the direction in which louvers are cut and raised is inclined in one direction only, and in which heat transfer performance is improved above that of conventional fins. To accomplish this, the relationship H>Qup/(Qup?1)×?H is satisfied. H represents the core height of the heat exchanger, Qup represents the ratio of the amount of heat exchanged per corrugation between one-directional louver fins and multi-directional louver fins in an airflow part, and ?H represents the amount of increase in a heat transfer reduction region of a heat exchanger core as a result of changing from multi-directional louver fins to one-directional louver fins.Type: GrantFiled: May 25, 2015Date of Patent: June 4, 2019Assignee: T.RAD Co., Ltd.Inventors: Takuya Bungo, Atsushi Okubo, Taiji Sakai, Hirotaka Ueki, Kazuo Maegawa
