Publication number: 20210131747Abstract: The invention relates to a heat exchanger having at least one partition and surface elements which project from at least one side of the partition and which enlarge the surface of the partition and around which a fluid can flow. The problem addressed by the present invention is that of proposing heat exchangers of low mass with high thermal transmission capacity. This problem is solved by means of a heat exchanger in which the surface elements are formed so as to project in the manner of fins from the partition, and the surface elements have reinforcement beads, wherein the reinforcement beads extend as far as the partition.Type: ApplicationFiled: August 3, 2018Publication date: May 6, 2021Inventors: Sebastian Unger, Uwe Hampel

Patent number: 8401143Abstract: It is an object of the present invention to specify an arrangement for X-ray computed tomography, which allows continuous three-dimensional imaging of the examination object or a partial volume of the examination object at a high temporal and spatial resolution, wherein a high spatial resolution defines both a high resolution within the slice plane and also in the axial direction.Type: GrantFiled: January 20, 2009Date of Patent: March 19, 2013Assignee: Helmholtz-Zentrum Dresden-Rossendorf E.V.Inventor: Uwe Hampel

Patent number: 8130899Abstract: An assembly for electron beam tomography affords continuous and simultaneous recording of two-dimensional slice images of an object in different irradiation planes with a high temporal and spatial resolution. Targets are penetrated by openings of a given width and with a regular arrangement in the circumferential direction. The openings in the targets are respectively situated on a path formed by the cross section of the shell of the electron beam cone with the respective target. The successive targets in the beam direction respectively are arranged with a small angular offset with respect to the optical axis to the respective target situated in front, and so an electron beam circulating along the shell of the electron beam cone successively irradiates the material webs between the openings of all targets with at least part of its cross section and an X-ray detector arc is arranged for each target in coplanar radial fashion in front of or behind the respective target.Type: GrantFiled: April 1, 2010Date of Patent: March 6, 2012Assignee: Helmholtz-Zentrum Dresden-Rossendorf E.V.Inventor: Uwe Hampel

Patent number: 7940038Abstract: Disclosed is an arrangement for quickly measuring the phase distribution or the component distribution in a flow cross section for substance mixtures also of a non-conducting type by measuring the complex electrical admittance. Said arrangement essentially features the following: at least one sine wave generator (5) which is mounted upstream from the transmitter electrodes (3a) of the excitation level and applies an alternating voltage to the transmitter electrodes (3a); current-to-voltage converters (7) which are mounted downstream from the receiver electrodes (3b), amplify the alternating current that flows from at least one excitation electrode (3a) through the medium to the receiver electrodes (3b), and convert said alternating current into a voltage signal; filter groups (10, 11, 16) and vector voltmeters (8) which are mounted downstream from the current-to-voltage converters (7) and allow the complex signal ratio Ua/Ue to be metrologically detected.Type: GrantFiled: April 18, 2007Date of Patent: May 10, 2011Assignee: Helmholtz-Zentrum Dresden-Rossendorf e.V.Inventors: Marco Jose Da Silva, Eckhard Schleicher, Uwe Hampel, Horst-Michael Prasser
