Patent number: 7610949Abstract: A heat exchanger with an external bypass is formed by a core portion including a plurality of stacked tubular members and a corrugated bypass tube positioned substantially parallel to the core portion. A first set of flow passages is defined within the tubular members for the flow of a first fluid therethrough, and a second set of flow passages is defined between adjacent tubular members as the tubular members are stacked together to form the core portion. A pair of external end plates is sealingly attached to transverse end wall portions of the stacked tubular members and to the ends of the bypass tube thereby forming the heat exchanger with an external bypass that comprises a single unit that can be brazed or joined together in a single operation.Type: GrantFiled: November 13, 2006Date of Patent: November 3, 2009Assignee: Dana Canada CorporationInventor: Herve Palanchon

Patent number: 7604045Abstract: Provided is an air conditioner for a vehicle, including a blower unit that blows air, an air conditioning case including an evaporator and a heater core, which are sequentially disposed in an airflow path, and an air inlet path that allows air to flow to an evaporator from the blower unit, wherein the airflow path includes a first path that allows air entered from the air inlet path to flow to a lower part of the evaporator and second and third paths that allow the air to flow to the lower part of the evaporator after passing through both sides of the evaporator. The air conditioner increases an amount of airflow and reduces airflow resistance since airflow paths are formed on both sides of the evaporator in addition to a direction perpendicular to the separator. Consequently, the airflow entering a lower part of the evaporator can be uniformly distributed.Type: GrantFiled: May 28, 2004Date of Patent: October 20, 2009Assignee: Halla Climate Control CorporationInventor: Seong Seck Han

Patent number: 7604042Abstract: A processing apparatus is provided with a showerhead for introducing a process gas into a processing vessel, and heaters for heating the showerhead to an elevated temperature. The processing apparatus is provided with a main flow line for a cooling liquid, and a bypass flow line connected to the main flow line so as to bypass the showerhead. A cooling liquid control system for controlling the flow of the cooling liquid includes shutoff valves, and a valve controller. The cooling liquid control system controls the flow of the cooling liquid such that the cooling liquid is prevented from flowing through the cooling passage while the showerhead is being heated to the elevated temperature, and such that the cooling liquid is made to flow through both the cooling passage and the bypass flow line while the showerhead is being cooled to a reduced temperature.Type: GrantFiled: May 17, 2002Date of Patent: October 20, 2009Assignee: Tokyo Electron LimitedInventor: Koichi Yamazaki

Publication number: 20090255650Abstract: A by-pass conduit for a stacked plate heat exchanger. The by-pass conduit comprises first and second plate members that each comprise a substantially planar central portion surrounded by an offset peripheral flange, the peripheral flanges of the first and second plates being sealably joined together and the planar central portions of the first and second plates being in spaced opposition to define a bypass channel. A flow restricting structure provides a fluid restricting barrier in the bypass channel, the flow restricting structure defining a calibrated by-pass passage that regulates the flow of fluid through the bypass channel.Type: ApplicationFiled: April 9, 2009Publication date: October 15, 2009Inventors: Desmond Magill, Asad Max Kaspar, Mark S. Kozdras

Publication number: 20090250203Abstract: The present invention provides a hot water supply apparatus capable of reducing energy consumption. That is, except during operation of heating water, when a detection temperature of a temperature sensor becomes equal to or lower than a set temperature, a circulating pump is operated and a compressor is operated at a second operating frequency having a lower frequency than a first operating frequency, thereby the compressor does not have to be repeatedly operated and stopped, and can be continuously operated in a state of reduced heating power.Type: ApplicationFiled: March 11, 2008Publication date: October 8, 2009Applicant: SANDEN CORPORATIONInventor: Satoshi IDA

Patent number: 7594536Abstract: An EGR cooler including tubes and a shell enclosing the tubes. Cooling water is supplied into and discharged from the shell. Exhaust gas is guided from a diesel engine into the tubes for thermal exchange of the exhaust gas with the cooling water. A bypass flow path for guiding the cooling water is constituted within the shell so as to prevent stagnation of the cooling water in the shell.Type: GrantFiled: May 22, 2003Date of Patent: September 29, 2009Assignees: Hino Motors, Ltd., Sankyo Radiator Co., Ltd.Inventors: Hiroyuki Sugihara, Makoto Tsujita, Yoji Yamashita, Naoto Miwa, Junji Honma
