The air flow direction generated by the blower and the air flow passage defined by the heat transfer surfaces through the heat exchanger may be substantially parallel or form an angle of no greater than approximately 30 degrees.Type: GrantFiled: June 6, 2003Date of Patent: September 21, 2004Assignee: Tecumseh Products CompanyInventor: Dan M.

Patent number: 6793011Abstract: A folded fin heat sink assembly and a method of fabricating a folded fin heat sink assembly for use as a cooling solution in micro-electronics and/or telecommunication applications. The heat sink assembly is formed by placing a sheet or paste of Sn—Zn solder upon a copper base plate, placing one or more aluminum folded fin assemblies on the solder sheet or paste, heating the base plate, the folded fin assembly and the solder to a temperature exceeding the liquidus temperature of the solder and allowing the solder to flow, and cooling the solder to form a soldered joint between the base plate and the folded fin assembly.Type: GrantFiled: February 14, 2002Date of Patent: September 21, 2004Assignee: ATS Automation Tooling Systems Inc.Inventors: Ross D. Armstrong, Alin Lla, Victor Kheil

Patent number: 6793013Abstract: A vertical polygonal heat exchange chamber includes an upper opening, a lower opening, and an enclosure formed between the upper and lower openings. The enclosure includes at least one tapered portion that narrows in a direction toward one of the openings. The tapered portion is lined with N first water tube panels arranged adjacent to and alternately with N second water tube panels, where N is an integer greater than two. Each of the first and second water tube panels is angled inwardly from the widest part of the tapered portion toward the interior of the enclosure, with each of the first water tube panels being angled inwardly to a greater degree than each of the second water tube panels.Type: GrantFiled: January 9, 2003Date of Patent: September 21, 2004Assignee: Foster Wheeler Energy CorporationInventor: Ponnusami K.

Patent number: 6793014Abstract: A method for manufacturing a heat transfer member comprises the step of subjecting a material to be worked, which is made of a metallic thin sheet, to a press forming utilizing a press-forming device to form a heat transfer member for a heat exchanger. The heat transfer member has on at least one portion thereof a heat transfer face that has opposite surfaces, which are to be come into contact with heat exchange fluids, respectively. The press-forming device comprises a pair of main molds for forming the heat transfer face on the material, which is to be conveyed in a single feeding direction, and two pairs of first auxiliary molds, which are disposed on upstream and downstream sides of the pair of main molds in the feeding direction of the material, so as to be exchangeable.Type: GrantFiled: May 29, 2002Date of Patent: September 21, 2004Assignee: Xenesys, Inc.Inventor: Toyoaki Matsuzaki

Patent number: 6793016Abstract: A vehicle air conditioning system includes a space air conditioning unit for blowing conditioned air into a passenger compartment, a seat air conditioning unit for blowing air into a vehicle seat, and a control unit for controlling the space air conditioning unit and the seat air conditioning unit. The control unit includes space controlling means for controlling the space air conditioning unit in accordance with a space control value calculated based on a space target air temperature, and seat controlling means for controlling the seat air conditioning unit in accordance with a seat control value calculated based on the space target air temperature. Further, the seat controlling means includes a first seat air conditioning means which determines the seat control value in a steady air conditioning state of the passenger compartment, and a second seat air-conditioning means which determines the seat control value in a transition air-conditioning state of the passenger compartment.Type: GrantFiled: January 25, 2001Date of Patent: September 21, 2004Assignee: DENSO CorporationInventors: Shinji Aoki, Takeshi Yoshinori, Koji Sakai, Yuichi Kajino

Patent number: 6793017Abstract: In a method and apparatus for transferring material in a wellbore in an earth formation, a pipe is inserted into the wellbore. A conduit is inserted alongside the pipe into the wellbore. The conduit is fixed to the pipe and has a first section with a perforated wall located adjacent a non-production interval of the formation, and has a second section with an unperforated wall located adjacent a production interval of the formation. The material is injected into the conduit and out the perforated wall of the first section of the conduit.Type: GrantFiled: July 24, 2002Date of Patent: September 21, 2004Assignee: Halliburton Energy Services, Inc.Inventors: Philip D.
