A pump system for use with a solar collector system which is used to heat a heat transfer fluid, includes a storage tank and the pump system having a first and second pump arranged in parallel which can pump the heat transfer fluid from the storage tank to a solar collector, so that should one pump fail the other pump can function, wherein the outlet of the first pump and the outlet of the second pump are connected to a valve arrangement, whereby when the first pump operates the outlet of the second pump is substantially closed by the flow from the first pump and when the second pump operates the outlet of the first pump is substantially closed by the flow from the second pump.

A method for operating a heat exchange system is provided. The heat exchange system includes at least one heat exchange chamber with heat exchange chamber boundaries which surround at least one heat exchange chamber interior of the heat exchange chamber, wherein the heat exchange chamber boundaries comprise at least one first opening for guiding in an inflow of at least one heat transfer fluid into the heat exchange chamber interior and at least one second opening for guiding out an outflow of the heat transfer fluid out of the heat exchange chamber interior, at least one heat storage material is arranged in the heat exchange chamber interior such that a heat exchange flow of the heat transfer fluid through the heat exchange chamber interior causes a heat exchange between the heat storage material and the heat transfer fluid.

A thin-film treatment apparatus for treating viscous material, including a housing, having a heatable and/or coolable housing casing, which encloses a rotationally symmetric treatment chamber extending in the axial direction, an inlet port, arranged in an inlet region of the housing, for feeding the material to be treated into the treatment chamber, an outlet port, arranged in an outlet region of the housings, for discharging the material from the treatment chamber, and a coaxially extending, drivable rotor shaft, arranged in the treatment chamber, for producing a material film on the inner face of the housing casing and for conveying the material in the direction from the inlet region toward the outlet region, the rotor shaft including a central rotor shaft body and rotor blades arranged on the circumference thereof, the radially outermost end of which rotor blades is distanced from the inner face of the housing casing.

An energy store of a motor vehicle may include at least one battery cell and a fluid channel having a temperature control fluid that may control a temperature of the at least one battery cell. The fluid channel may be defined by a fluid channel arrangement having two walls and a plurality of spacers arranged therebetween. The plurality of spacers may be configured for a needs-based temperature control of the at least one battery cell. The plurality of spacers may be arranged so that a coolant flow is conducted directly to a hot spot of the at least one battery cell. At least one of the two walls may comprise an organic sheet and may be connected, via glue or welding, to the plurality of spacers.

A valve system comprises a plurality of motors and a plurality of valves. The plurality of motors is formed from a printed circuit board. The plurality of valves is actuated by the plurality of motors.

Furnace for melting inorganic salts, comprising a container, at least one inlet area for solid inorganic salts, at least one outlet area for molten inorganic salts and at least one heat exchanger tube or coil. Each heat exchanger tube includes an inlet section connected to the outer side wall of the container, a spiral section substantially along the inner side walls of the container defining an internal space, with this spiral section arranged in a substantially horizontal plane, and an outlet section which is substantially vertical and goes downwards towards the bottom area or upwards towards the top area of the container. This furnace provides better safety and performance than previously known furnaces.

A heat exchanger is provided that includes a housing and an exchanger region which is arranged in the housing and has tubes and at least one base, wherein the tubes are connected to the at least one base, wherein the housing is manufactured from a plastic and has a housing inner surface, wherein the housing inner surface is covered at least in regions or in sections by at least one metallic element for protecting the housing from a thermal load. The invention further relates to a method for producing a heat exchanger.

A water-cooled EGR cooler is to be supplied with exhaust gas from an exhaust line and is to re-circulate the cooled exhaust gas to an intake line. A housing has an exhaust inlet, an exhaust outlet, a coolant inlet, and a coolant outlet. A heat exchange member is disposed in the housing and includes exhaust gas passages from the exhaust inlet to the exhaust outlet at a predetermined interval and also includes a coolant passage through which coolant can flow from the coolant inlet to the coolant outlet between the exhaust gas passages. A pipe member includes a bypass passage formed between an upper surface of the heat exchange member and an inside upper surface of the housing to allow the exhaust gas to bypass the heat exchange member and flow between the upper surface of the heat exchange member and the coolant outlet.

A method includes building a tubular object by a layer-by-layer additive manufacturing process. A structure integrally connected to the tubular object for supporting a portion of the tubular object is formed during building of the tubular object. The structure provides vibration dampening, heat shielding, heat transfer, stiffening, energy absorption, or mounting after the tubular object is built.

An apparatus (1) for adjusting the heat exchange, comprising shielding means (10) intended to be arranged facing at least one portion of a heat exchanger (2), and provided with at least one screen (11) movable between a position of maximum covering (C) of the heat exchanger (2) and an exposure position, in which the heat exchanger (2) is left at least partially uncovered by the screen (11).
