A heat exchanger comprising a primary side; a secondary side; at least one primary structure on the primary side defining at least one primary space on the primary side; and at least one secondary structure on the secondary side defining at least one secondary space on the secondary side; wherein one or more of the at least one primary structure and one or more of the at least one secondary structure delimit a coolant volume separated from the at least one primary space and separated from the at least one secondary space; wherein one or more of the at least one primary structure and/or one or more of the at least one secondary structure comprises a three dimensional lattice body.

Heat exchanger and electric arrangement comprising heat exchanger

A glass furnace for continuous operation, including a melting tank for containing a glass melt, and at least one magnetic actuator configured to generate a time-varying magnetic field suitable for moving a stirring body immersed in the glass melt.

An apparatus for electromagnetic stirring of the steel melt in an electrical arc furnace includes two electromagnetic stirrer units, a current supply, and a control unit. The two stirrers are mounted on an outer bottom surface of the electrical arc furnace at opposites sides of a central position of the bottom surface, the current supply is operatively connected to the two electromagnetic stirrer units, and the control unit is operatively connected to the current supply to control the operation of the two electromagnetic stirrer units.

An apparatus for crystallization of silicon includes a crucible for containing silicon, a heating and heat dissipating arrangement provided for melting the silicon contained in the crucible and for subsequently solidifying the molten silicon, and an electromagnetic stirring device provided for stirring the molten silicon in the crucible during the solidification of the molten silicon. A control arrangement is provided for controlling the heating and heat dissipating arrangement to solidify the molten silicon at a specified solidification rate and for controlling the electromagnetic stirring device to stir the molten silicon in response to the specified solidification rate of the molten silicon such that the ratio of a speed of the molten silicon and the specified solidification rate is above a first threshold value.
