Patent number: 6056043Abstract: An accumulator (20) operating according to the layered storage principle is used in connection with the cooling loop of a vehicle, and includes charge alternation devices (34, 38) adapted to upper and lower storage regions (26, 28). The inflow and outflow velocity of the coolant should be between 0.1 and 0.5 m/s, and charging or discharging of the accumulator (20) should occur within 10 to 100 seconds. Inflow and outflow lines (32, 36) run within an insulation space (40) in the fashion of a thermosiphon.Type: GrantFiled: March 18, 1997Date of Patent: May 2, 2000Assignee: Langerer & Reich GmbHInventors: Roland Strahle, Bernhard Stephan, Bernd Streicher

Patent number: 5605190Abstract: A heat accumulator, in particular latent-heat accumulator, has an inner casing containing an accumulator core and with an outer casing enclosing the inner casing at a distance thereto so as to form an insulation space, the insulation space being baked out and evacuated. The inner casing has a pipe connection with a fill opening through which the storage medium can b introduced and which can be closed by a mechanical closing element after the storage medium has been introduced. The outer casing has a pipe connection with a fill opening through which the insulation space can be filled with insulating medium and or evacuated and which can be closed by a mechanical closing element. The pipe connection of the inner casing is disposed coaxially to the pipe connection of the outer casing. This simplifies manufacture of the heat accumulator.Type: GrantFiled: March 16, 1995Date of Patent: February 25, 1997Assignees: Langerer & Reich GmbH & Co, Bayrische Motoren Werke AktiengesellschaftInventors: Roland Strahle, Stephan Horz, Henryk Bednarek

Patent number: 5449035Abstract: A heat accumulator, in particular a latent heat accumulator has an inner jacket arranged to surround an accumulator core and an outer jacket surrounding the inner jacket so as to form an insulation chamber therebetween, two conduits extending from the insulating chamber outside and forming a supply conduit and a return conduit for a heat transporting medium and elements for counteracting heat losses and associated with the conduits, each of the conduits in its course having a conduit interruption and being provided with a thermal insulation in the region of the conduit interruption so as to form the heat losses counteracting elements.Type: GrantFiled: June 4, 1993Date of Patent: September 12, 1995Assignee: Langerer & Reich GmbH & Co.Inventors: Roland Strahle, Stephan Horz, Jochen Letsch

Patent number: 5345674Abstract: In a method of making a heat exchanger having a heat exchanger network with a plurality of tubes and at least one base plate having a plurality of passages for tube ends, the passages in the base plate are triangular, and the tube ends are triangular prior to insertion into the base plate. The triangular tube ends are inserted into the triangular passages in the base plate and thereafter expanded to a tight fit.Type: GrantFiled: April 2, 1993Date of Patent: September 13, 1994Assignee: Langerer & Reich GmbH & Co.Inventors: Wolfgang Knecht, Roland Strahle, Gerhard Weiss

Patent number: 4893391Abstract: The method of making a round-rolled part for a heat exchanger comprises connecting the tubes and the irradiating elements to each other to form a rectilinear network, clamping both ends of the rectilinear network and stretching and bending the clamped network so that it assumes an arcuate shape. The premise adopted is that of a network of flat tubes consisting of rectangular tubes and irradiating elements between them, the tube network being bent round around a narrow side of the tubes. The network has one end rigidly gripped on the bending tool. The tubular network is wound onto it by rotating the latter. There is applied to the other end of the network a retaining force which counteracts the winding-on force and which maintains the tube network under tensile stress. The apparatus comprises a rotatable round bending tool and a clamping means which tangentially clamps the end of the network. Spaced from the round bending tool there is a mating holder for firmly gripping the other end of the network.Type: GrantFiled: June 15, 1988Date of Patent: January 16, 1990Assignee: Kuhlerfabrik Langerer & Reich GMBH & Co.
