Patent number: 9410749Abstract: The invention relates to an heat exchanger element of a plate type, with one internal flow passage, comprising two plates defining an inlet, an outlet and an internal passage extending between said inlet and said outlet, whereas said passage is between two generally parallel plates of self supporting polymer material. The present invention also relates to the use of such an exchanger element as collector in a solar energy arrangement, as chilled beam, as hear distributing element, as subterranean collector, as exchange element in industrial processes and as heat absorber in arrangements for cooling electrical components that are negatively affected by being close to elements having electrical conductivity.Type: GrantFiled: September 22, 2009Date of Patent: August 9, 2016Assignee: JLO INVEST ABInventor: Per Gunnar Eriksson

Patent number: 8609044Abstract: A micro vial assembly for performing microwave-assisted chemical reactions on small reaction mixture volumes is disclosed, wherein a reaction vessel (10) is sealed through a diaphragm (30) that is capped over an open end of the reaction vessel. The reaction vessel mouths in an end plane of a sleeve (20) surrounding the reaction vessel, the diaphragm being clamped for sealing the open end of the vessel by means of a cap (40) which is secured to the sleeve. The sleeve provides a radial extension of the reaction vessel in order to bridge the radial distance between a wall of the reaction vessel and other components in a system for performing microwave-assisted chemical reactions.Type: GrantFiled: December 18, 2003Date of Patent: December 17, 2013Assignee: Biotage ABInventors: Johan Ulin, Per-Gunnar Eriksson, Fredrik Ekdahl

Publication number: 20110232722Abstract: The invention relates to a heat transfer element and an arrangement using such an element to lower the temperature of solar cells. The heat transfer element is arranged to be placed on the shadow side of and in contact with a panel of solar cells and configured for collecting heat from the solar cells, said element comprising an inlet, an outlet and a internal passage extending between said inlet and said outlet and being arranged to guide a heat transporting fluid. Also the passage is defined between two generally parallel sheets. The arrangement comprises a heat transfer element arranged to be placed on the shadow side of and in contact with the panel and a system feeding a heat transporting fluid to said inlet and receiving the heat transporting fluid from said outlet.Type: ApplicationFiled: September 22, 2009Publication date: September 29, 2011Applicant: SUNCORE ABInventor: Per Gunnar Eriksson

Patent number: 6554955Abstract: An apparatus for producing a flexible heat-exchange device for taking heat from or delivering heat to the ambient surroundings, wherein the device includes a body comprised of mutually joined flexible mats and including an internal passageway for the heat-carrying fluid. The apparatus includes two mould dies which can be brought together and have on their mutually opposing surfaces generally mirror-image patterns in the form of recesses in the respective abutment surfaces of the tools, the recesses corresponding to the extension of a flow passageway, and two mat joining tools which can be brought together and have on their mutually opposing surfaces a generally mirror-image pattern in the form of abutment surfaces that form the electrodes of the mat joining tools, wherein the electrodes are disposed in a pattern corresponding to the delimitations of the flow passageway, and the electrodes can be connected to a high frequency welding unit.Type: GrantFiled: July 24, 2001Date of Patent: April 29, 2003Assignee: Tex Sun Energy ABInventor: Per Gunnar Eriksson
