When the heat transfer sheets (70) are stacked, they create passageways (79) between them that direct air/gas through them. The ridges (75,85) redirect the air flow near the surface of the heat transfer sheet (70) imparting turbulence reducing laminar flow to improve heat transfer. The heat transfer sheets (80) employ curved ridges (95) having valleys (97) between them that define passageways (99) that constantly redirect the air/gas flow minimizing turbulence, creating efficient heat transfer.Type: ApplicationFiled: June 1, 2011Publication date: December 6, 2012Applicant: ALSTOM TECHNOLOGY LTDInventors: Lawrence G.

Publication number: 20120267084Abstract: A double-wall heat exchanger includes a plurality of heat exchange plate pairs. Each heat exchange plate pair forms a double-wall structure including two heat exchange plates that are at least partially separated by a leak space. At least one weep hole is disposed through the plurality of heat exchange plate pairs and intersects the leak spaces of the plurality of plate pairs to channel leaking fluid from the leak spaces to a location outside of the heat exchanger. The at least one weep hole is positioned on a surface of the heat exchanger at a location that is spaced from a side boundary of the heat exchanger thereby enabling an operator of the heat exchanger to observe a leakage on the surface of the heat exchanger.Type: ApplicationFiled: April 25, 2011Publication date: October 25, 2012Applicant: ITT Manufacturing Enterprises, Inc.Inventor: Gary A.

Patent number: 8291892Abstract: A heat exchanger suitable for cooling exhaust gases and a method of making same are disclosed. The heat exchanger includes an outer casting member having first and second ends and forming a housing and a plurality of channel members forming alternating first and second flow channels for the flow of an exhaust gas through the first flow channels and coolant through the second flow channels. The channel members form a core having first and second ends, this core being mounted in the casting member. A first flange is fixedly attached to a first end of the core so as to form a sealed joint. A second flange is fixedly attached to the second end of the core so as to form another sealed joint. The first and second flanges are each coupled by fasteners to their respective ends of the casting.Type: GrantFiled: February 14, 2012Date of Patent: October 23, 2012Assignee: Dana Canada CorporationInventors: Herve Palanchon, Hans Katzmaier, Bruno Chapoutol

Publication number: 20120247741Abstract: A heat exchanger comprises a first plate and a second plate. A coolant flow passage is formed by brazing the first plate and the second plate by use of a first brazing filler metal. A pipe is brazed between a first groove portion provided in the first plate and a second groove portion provided in the second plate by use of a second brazing filler metal. A pair of first flanges provided contiguously with the first groove portion. Each of the first flanges includes an inner surface. A pair of second flanges provided contiguously with the second groove portion. Each of the second flanges includes an inner surface. At least one of the inner surfaces of the first flanges and the inner surfaces of the second flanges is covered with the second brazing filler metal. The first and second flanges are held by jigs upon brazing of the pipe.Type: ApplicationFiled: March 23, 2012Publication date: October 4, 2012Applicants: SHOWA DENKO K.K., KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Takashi OKAMOTO, Tomoya HIRANO

Publication number: 20120222847Abstract: The Invention relates to an exchanger comprising a network of channels extending between two parallel faces, in order to allow the circulation of a heat transfer fluid in the channels and the heat exchange between this heat transfer fluid and the outside through at least one of the faces. The network of channels is formed by a three-dimensional hollow laminated panel based on fibres hardened by the impregnation of a resin, comprising two two-dimensional woven layers which are impervious and stiff forming the parallel faces, and a stiff weaving of orthogonal fibres, connecting the two layers together by providing a hollow intercalated space by forming rows of parallel walls between them defining the channels.Type: ApplicationFiled: March 1, 2011Publication date: September 6, 2012Applicant: MARINE TECHNIQUE MEDITERRANNEEInventor: M.

Publication number: 20120217826Abstract: A cooling device includes an inner sleeve with an outer surface, an outer sleeve surrounding the inner sleeve, and two end portions extending between the inner sleeve and the outer sleeve at the ends. The inner sleeve, the outer sleeve and the end portions define a peripheral space. A flow guiding structure defines N channels in the peripheral space for coolant to flow, where N is an integer equal to or greater than 1. Each channel has at least two branches, and N pairs of inlet and outlet corresponding to the N channels. The branches of each channel are in fluid communication with a respective pair of inlet and outlet. Each branch extends over a half circumferential part of the outer surface of the inner sleeve. An electric motor incorporating the cooling device is also provided.Type: ApplicationFiled: February 24, 2012Publication date: August 30, 2012Inventors: Mao Xiong Jiang, Yu Li, Gang Li, Yong Wang, Hai Hui Xiang

Patent number: 8240361Abstract: The invention relates to a combined thermal protection and surface temperature control apparatus. In one embodiment, a combined thermal protection and surface temperature control apparatus comprises a porous member having an entrance side, and a separate exit side. One or more coolant entrance channels extend through the entrance side, extend part-way through the porous member, and end within the porous member before reaching the exit side. Conversely, one or more coolant exit channels begin within the porous member, extend through a portion of the porous member, and extend through the exit side. The coolant entrance and exit channels may be parallel and may alternate. The channels may only extend across a portion of the thickness of the porous member.Type: GrantFiled: November 2, 2006Date of Patent: August 14, 2012Assignee: The Boeing CompanyInventors: William W.

Patent number: 8235098Abstract: A flat tube for a heat exchanger having a stack of such flat tubes. The flat tube has a plurality of spaced-apart dimples formed on each of its opposite faces. At least some of the dimples on each face have an elongate plan shape, at least some of the elongate dimples being obliquely oriented such that their major axes form oblique angles with a longitudinal axis of the tube. The obliquely oriented elongate dimples are positioned such that when two of the tubes are stacked, the obliquely oriented elongate dimples on opposing faces of the tubes contact one another and the major axes of each contacting pair of elongate dimples are non-parallel to each other. Each contacting pair of elongate dimples of adjacent tubes thus forms a “cross” or “X”.Type: GrantFiled: January 24, 2008Date of Patent: August 7, 2012Assignee: Honeywell International Inc.Inventor: Keith Agee
