Patent number: 11428474Abstract: A plate heat exchanger includes a stack of plate pairs with gaps between adjacent pairs, arranged to provide flow paths for a first fluid to pass through inner volumes of the plate pairs while simultaneously allowing a second fluid to flow over the outer surfaces of the plate pairs. At least one cylindrical fluid manifold for the first fluid extends through the plate pairs. A non-planar cap is arranged at one end of the plate heat exchanger to close off the cylindrical fluid manifold. A reinforcement plate is arranged at that end between the non-planar cap and an end plate of the plate heat exchanger. The position of the non-planar cap relative to a central axis of the cylindrical fluid manifold is maintained in order to prevent failure of the plate heat exchanger due to internal pressurization.Type: GrantFiled: May 20, 2020Date of Patent: August 30, 2022Assignee: Modine Manufacturing CompanyInventors: Alexander Riebel, Wolfgang Schatz-Knecht

Patent number: 10302366Abstract: A brazed heat exchanger includes plates that are stacked or nested to define flow channels for multiple media. Inserts are arranged within at least some of the flow channels. Two different braze alloys having compositions based on different metals are used to form braze joints between the plates and the inserts. In some cases, a copper-based braze alloy is used for joints corresponding to flow channels for one of the media in order to provide high pressure-resisting strength to those flow channels, while an iron-based braze alloy is used for joints corresponding to flow channels for another of the media where dissolved copper is undesirable.Type: GrantFiled: October 9, 2015Date of Patent: May 28, 2019Assignee: Modine Manufacturing CompanyInventor: Wolfgang Schatz-Knecht

Patent number: 7834633Abstract: There is described a method and a system for monitoring a protective apparatus, which is connected upstream of a switching device and is connected to the switching device via at least one main current path. The wiring complexity for monitoring of the protective apparatus is minimized. This is achieved by virtue of the fact that the sate of the protective apparatus is determined by a tap of the at least one main current path at or in the switching device by means of an evaluation unit. As a result of this direct evaluation of the switching state of the protective organ on the switching device, the wiring which until now has been required for an addition auxiliary switch on the protective device is dispensed with a possible fault source also being minimized along with the wiring complexity. For this purpose, the proposed solution is also independent of the physical design (branch-oriented or row-oriented, distance between the devices) in a switchgear cabinet.Type: GrantFiled: September 21, 2006Date of Patent: November 16, 2010Assignee: Siemens AktiengesellschaftInventors: Peter Hartinger, Rainer Keil, Wolfgang Schatz

Publication number: 20100104875Abstract: At least one embodiment of a plunger has, when viewed in a longitudinal direction, a central region and two outer regions adjoining the central region. The outer regions are injection-moulded from a non-magnetizable material. In the central region, a magnetizable material is integrated in the plunger. In at least one embodiment, an injection-mouldable material is used as the magnetizable material, and the plunger including the magnetizable material is manufactured by way of a two-component injection-moulding process. A defined magnetization is impressed on a section of the central region once the magnetizable material has been integrated in the plunger.Type: ApplicationFiled: August 24, 2007Publication date: April 29, 2010Inventors: Erhard Carls, Helmut Kraus, Stefan Langen, Werner Olbrich, Wolfgang Schatz
