Patent number: 8746961Abstract: One aspect of the present invention relates to a method for increasing the temperature of a substance which is initially in an at least partly solidified state in a container, where at least one heat exchanger is arranged in the container. One object is to obtain that the temperature of a substance may be changed relatively fast. This is obtained by having pumping means for displacing the substance, exchanging heat between a heat exchanger and the substance, displacing substance with the pumping means for increased heat exchange between the heat exchanger and the substance, as well as stirring the substance with the pumping means by displacing the substance inside the container. When the substance is displaced, then not only stagnant substance is in contact with the heat exchanger for heat exchange. The amount of substance in contact with the heat exchanger is thereby greatly increased, and the heat transfer is less dependent on thermal conductivity of the substance.Type: GrantFiled: April 20, 2005Date of Patent: June 10, 2014Assignee: Aarhuskarlshamn Denmark A/SInventor: Anders Kromand Hansen

Patent number: 8734005Abstract: One aspect of the present invention relates to a method for increasing the temperature of a substance which is initially in an at least partly solidified state in a container, where at least one heat exchanger is arranged in the container. One object is to obtain that the temperature of a substance may be changed relatively fast. This is obtained by having pumping means for displacing the substance, exchanging heat between a heat exchanger and the substance, displacing substance with the pumping means for increased heat exchange between the heat exchanger and the substance, as well as stirring the substance with the pumping means by displacing the substance inside the container. When the substance is displaced, then not only stagnant substance is in contact with the heat exchanger for heat exchange. The amount of substance in contact with the heat exchanger is thereby greatly increased, and the heat transfer is less dependent on thermal conductivity of the substance.Type: GrantFiled: June 28, 2011Date of Patent: May 27, 2014Assignee: Aarbuskarlshamn Denmark A/SInventor: Anders Kromand Hansen

Patent number: 8720199Abstract: A heat exchanger for heat exchange between a first fluid and a second fluid is provided that includes: a block for guiding the first fluid and the second fluid separately and in a heat-exchanging manner, and a fluid connection for the first fluid. The block comprises a housing provided with a chamber through which the second fluid can flow, and a block end element for the fluid-tight separation of the chamber and the fluid connection. The housing can be provided for connecting the block to the fluid connection. The block end element is not used to connect the block to the fluid connection but rather preferably only the housing. The housing can be thickened accordingly in the region of the block connection. The fixing point for the block end element to the housing and the fixing point for the fluid connection to the housing are at a distance from each other.Type: GrantFiled: August 27, 2009Date of Patent: May 13, 2014Assignee: Behr GmbH & Co.

Patent number: 8672021Abstract: A shell and tube heat exchanger (which can be a boiler) which includes a plenum chamber defined by at least one of the tube-sheets and a diaphragm plate. In this plenum chamber a system of outer and inner annuli around each of the tubes created by a system of baffle tubes that surround each fluid tube and a holes in the thick tube-sheet of the exchanger. This arrangement allows the high pressure cooling fluid in the shell to keep the high temperature low pressure fluid tube inlet, and the associated tube-sheet cool under very high hot fluid flow rates at lower cost, smaller footprint and with lower pressure loss of the low pressure hot fluid than previous art.Type: GrantFiled: February 12, 2010Date of Patent: March 18, 2014Inventor: Alfred N. Montestruc, III

Publication number: 20140041840Abstract: An apparatus for transferring heat between a first fluid and second fluid in a motor vehicle includes a housing, a first header, a second header, and a plurality of heat exchange tubes. The housing defines a chamber and includes a first inlet, a second inlet, a first outlet, and a second outlet. The first and second headers separate a central portion of the chamber from a first and second header portion of the chamber, respectively. The first inlet and the first outlet are in fluid communication with the central portion. The second inlet is in communication with the first header portion. The second outlet is in fluid communication with the second header portion. Each of the plurality of heat exchange tubes passes through the central portion of the chamber and has a first end in fluid communication with the first header portion and a second end in fluid communication with the second header portion.Type: ApplicationFiled: August 6, 2013Publication date: February 13, 2014Applicant: Cooper-Standard Automotive, Inc.Inventors: George Moser, Adam Ostapowicz, Lawrence C.

Patent number: 8573285Abstract: A variety of methods of forming polymer manifolds and the resulting manifold structures are described. The described manifolds are well suited for use in heat exchangers and a variety of other applications. In one aspect a polymer manifold includes a multiplicity of tubes having first ends that are received by a manifold housing. A polymer film is secured to the manifold housing and to the ends of each of the tubes. The film is arranged to seal the housing while leaving the openings of the tubes exposed to thereby create a manifold. In some embodiments, a potting material is used to reinforce the film. In a method aspect, a manifold may be formed by positioning first ends of the tubes in a manifold housing and welding a polymer film to the manifold housing and to distal tips of the tubes. Openings for the tubes are then formed in the film by directing heat towards the film which melts or vaporizes the film in the regions of the tube openings.Type: GrantFiled: March 24, 2011Date of Patent: November 5, 2013Inventor: Richard O.
