Patent number: 6595272Abstract: In a double heat exchanger having a condenser core and a radiator core, a protrusion is provided on a condenser header tank which contacts a radiator header tank so that a clearance between the condenser header tank and the radiator header tank around the protrusion is in a range of 0.5 mm-1.5 mm. Further, a coating-removing restriction material such as magnesium for restricting the removal of an oxidation coating formed on the surface of a brazing material is added to one of the contact areas of the protrusion and the contact area of the condenser header tank. Thus, it can prevent brazing material from being collected in the contact areas of the protrusion and the condenser header tank by a capillary phenomenon during brazing. Accordingly, the heat-transmitting area between the radiator header tank and the condenser header tank is not increased, and the heat-radiating capacity of the condenser core is increased.Type: GrantFiled: September 21, 2000Date of Patent: July 22, 2003Assignee: Denso CorporationInventors: Akira Uchikawa, Norihisa Sasano, Satomi Muto, Takaaki Sakane

Patent number: 6578650Abstract: An intake duct (intake air path) utilizes an upper beam member of a front end panel, the cross section of which is substantially a C-shape. When the front end panel is assembled into a vehicle with the duct member being attached to the front end panel, assembling of the intake duct is completed. In another embodiment, a space (intake duct) is formed in a first pillar section of the front end panel with an intake port and a discharge port, which communicate the inside of the space with the outside of the space; the parts are arranged such that they are shifted from each other when they are viewed from the front side of the vehicle. Thus, a current of air flowing into the space flows in a crank-shape and passes outside of the space. Accordingly, foreign objects such as rain water and snow, which have entered the space together with air, will not flow together with the current of air flowing in the space. Therefore, the foreign objects such as rain water and snow remain in the space.Type: GrantFiled: June 19, 2001Date of Patent: June 17, 2003Assignee: Denso CorporationInventors: Ikuo Ozawa, Norihisa Sasano, Toshiki Sugiyama

Publication number: 20030051858Abstract: A first pipe 231 and a second pipe 232 are connected so that at least one of connectors 233 and 234 is located in a through-hole 133, in a state in which both the connectors 233 and 234 are connected. In this way, since the through-hole 133 is brought to a state of being filled in by the connector 233, the gap between a refrigerant pipe 230 and the edge of the through-hole 133 can be considerably reduced. It is, therefore, possible to prevent hot air from moving to the front side of a vehicle, in front of a panel 100 through the gap between the refrigerant pipe 230 and the edge of the through-hole 133 without the necessity of filling in the gap with a filling means such as rubber (a grommet) and packing.Type: ApplicationFiled: September 16, 2002Publication date: March 20, 2003Inventors: Norihisa Sasano, Akira Uchikawa, Satoshi Matsuura, Kouichi Mizukami

Patent number: 6364403Abstract: A vehicle front end member including at least a radiator has an upper protrusion fixed to an upper insertion hole of a vehicle front end panel, and a lower protrusion fixed to a lower insertion hole of the front end panel. When an exterior force larger than a predetermined value is applied to the vehicle from a front side, a fixing state of the upper protrusion into the upper insertion hole is released, while a fixing state of the lower protrusion into the lower insertion hole is maintained. Therefore, is can prevent all the front end member from being separated from the front end panel when the exterior force is applied to the vehicle from the front i side. Accordingly, a damage of the front end member due to the exterior force is prevented while a collision of the front end member on a road surface is prevented.Type: GrantFiled: October 19, 2000Date of Patent: April 2, 2002Assignee: Denso CorporationInventors: Ikuo Ozawa, Noriaki Maeda, Takuya Usami, Toshiki Sugiyama, Norihisa Sasano

Patent number: 6357521Abstract: A radiator has plural metal tubes and a metal header tank. The header tank has plural connection portions each of which is connected to each of the tubes, and plural reinforcement ribs formed opposite the connection portions at a non-connection portion of the header tank to which no tube is connected. The reinforcement ribs and the connection portions are arranged in a longitudinal direction of the header tank at substantially the same pitch, so that each of the reinforcement ribs is disposed opposite each of the connection portions. Therefore, a rigidity of the non-connection portion is increased by the reinforcement ribs, and an internal pressure of the header tank is restricted from being intensively applied to the non-connection portion. As a result, a mechanical strength of the header tank is sufficiently increased without increasing a thickness of a metal plate from which the header tank is formed.Type: GrantFiled: March 24, 2000Date of Patent: March 19, 2002Assignee: Denso CorporationInventors: Tatsuo Sugimoto, Norihisa Sasano, Satomi Muto, Takaaki Sakane, Akira Uchikawa
