Patent number: 7619887Abstract: The invention relates to an arrangement for cooling equipment and network cabinets, particularly server cabinets, in which the fans are integrated into a door. The resulting fan door, in the closed position, covers an access area of the rear of the cabinet and longitudinally adjacent to the fan door is arranged in fixed manner an air-to-fluid heat exchanger, whilst covering a residual area of the rear of the cabinet and to which is articulated the fan door. The heat loss given off to a cooling liquid, particularly cold water, in the heat exchanger is removed via a pipe system outside the cabinet installation area and rigid connecting pipes of a gas-tight material can be used for the connection of the heat exchangers of the individual cabinets to the building-side pipe system.Type: GrantFiled: December 5, 2005Date of Patent: November 17, 2009Assignee: Knuerr AGInventors: Peter Koch, Rainer Bretschneider, Heiko Ebermann, Manfred Willnecker, Harald Fonfara, Thorsten Miltkau, Thomas Künkler, Lars Weiβmann

Publication number: 20090185348Abstract: The invention relates to a system for cooling electrical and electronic components and devices placed in a housing. The invention is particularly intended for outdoor cabinets and housings of the telecommunications technology. In order to create a cooling system in which an inexpensive filter is used and positioned in such a way as to ensure an extremely good sealing action, a filter trough is placed in a housing wall or door, in which the filter is received so as to be detachable and replaceable from the outside and is sealed against the filter trough on its air outlet side with the aid of a circumferential seal.Type: ApplicationFiled: March 9, 2007Publication date: July 23, 2009Applicant: Knuerr AGInventors: Rainer Bretschneider, Lars Gallasch, Wolfgang Trepte

Publication number: 20090126385Abstract: The invention relates to a switch cabinet with a closed cooling air circuit and a heat exchanger for dissipating the heat loss from electronic modular units located in an inner area. For efficient cooling and to avoid the removal to the switch cabinet environment of condensate produced in the heat exchanger, at least one atomizing device is provided and transforms the condensate into aerosols. The condensate aerosols are immediately resupplied to the cooling air circuit, preferably the hot, dry exhaust air flow, so that simultaneously an advantageous atmospheric humidity stabilization in the switch cabinet is ensured.Type: ApplicationFiled: January 5, 2006Publication date: May 21, 2009Applicant: Knuerr AGInventor: Wolfgang Trepte

Publication number: 20090120622Abstract: The invention relates to a heat exchanger for water-cooled network cabinets and to a method for cooling network cabinets, particularly server cabinets. The heat exchanger is constructed as an air-water heat exchanger in redundant form and ensures a leaktight arrangement and cooling in a network cabinet. The heat exchanger has two heat exchanger elements with separate cooling water connections which, accompanied by the formation of a space, are provided for the supply of exhaust air from the cabinet interior. A partition is adjustably placed in the space and in the case of a fault, e.g. if one heat exchanger element or a cooling circuit fails, the corresponding heat exchanger element is aerodynamically blocked with the aid of the partition. The entire exhaust air is cooled in the intact heat exchanger element and supplied to the cabinet interior, so that no interruption of operation is necessary.Type: ApplicationFiled: January 3, 2007Publication date: May 14, 2009Applicant: KNUERR AGInventor: Peter Koch

Publication number: 20080070492Abstract: The invention relates to a cooling system for equipment and network cabinets, particularly server cabinets, and to a method for cooling equipment and network cabinets. The cabinets have an airtight construction and are provided with an atmospheric humidity stabilization in order to avoid damage as a result of condensate formation and a reduction of the absolute atmospheric humidity. According to the invention the atmospheric humidity stabilization is brought about by a clearly defined and in particular controllable external air supply and a possible removal of air from the closed cooling air circuit.Type: ApplicationFiled: August 29, 2005Publication date: March 20, 2008Applicant: KNUERR AGInventors: Peter Koch, Heiko Ebermann

Patent number: 7254022Abstract: The invention relates to a cooling system for equipment and network cabinets and to a method for cooling such cabinets, together with the electronic modules located therein. In order to achieve with extremely simple means and particularly low capital and operating expenditure a high power cooling for densely packed cabinets and cabinet arrangements, particularly server cabinets in data processing centers and the like, an air ducting is provided in a substantially airtight cabinet with equally long airflow paths and therefore equal flow resistances, together with a uniform supply air temperature. The circulated airflow is cooled with the aid of an air-water heat exchanger in the lower cabinet area. The heated exhaust air is collected in a collecting duct with a rising flow, reversed and supplied in a falling flow to the heat exchanger.Type: GrantFiled: May 6, 2004Date of Patent: August 7, 2007Assignee: Knuerr AGInventor: Heiko Ebermann
