In a method for producing a heat exchanger tube bundle for a heat exchanger of an electrochemical energy accumulators, heat exchanger channels and an intended profile are incorporated into material strips by deep drawing. A forward-flow distribution aperture is incorporated into a first such material strip from step b) (first heat exchanger plate), and return collecting apertures are incorporated into a second such material strip, forming first and the second heat exchanger plates. The latter are aligned in such a manner that webs of the two heat exchanger plates border each other, and the heat exchanger channels form heat exchanger tubes. The heat exchanger plates arranged in this manner are joined together to form a heat exchanger tube bundle. A corresponding pressure welding apparatus, a heat exchanger tube bundle, a heat exchanger module, a heat exchanger with two or more heat exchanger modules, and an electrochemical energy accumulator with a heat exchanger of this type are also disclosed.

Heat exchanger comprising deep-drawn heat exchanger plates

A heat exchanger structure for a plurality of electrochemical storage cells has at least one duct component through which thermal control medium flows. The duct component has two material strips which are arranged parallel to one another and between which a heat exchanger duct is formed. The material strips have shaped portions adapted to the storage cells. The heat exchanger structure is useable, for example, for a motor vehicle battery.

Heat exchanger structure for a plurality of electrochemical storage cells

A Battery container is provided for a plurality of cylindrical accumulator elements which are arranged parallel to one another in rows and/or layers essentially horizontally. At least one first fixing element is arranged on a bottom plate and a cover plate of the battery container. The fixing elements extend transversely to the longitudinal axes of the accumulator elements and, with a form-locking action, fix and support the accumulator elements in the horizontal and the vertical direction. In the case of a layer-type arrangement of the accumulator elements, additional fixing elements are provided which are arranged between two layers of accumulator elements respectively and which also extend transversely to the longitudinal axes of the accumulator elements and, while acting upon the accumulator elements in a form-locking manner, fix and support the accumulator elements in the horizontal and vertical direction.

Battery container and motor vehicle

This invention relates to a battery container which can be fastened in a sealing and detachable manner directly in the supporting floor structure of a body of a vehicle. The battery container is formed of a material, particularly sheet metal, which is ductile also at low freezing temperatures, and is dimensioned such in its wall thickness that, in the case of a crash, although it rips in a defined manner, it does not tear so far that individual cells can fall out of the battery container. In the battery container, the flat sides of inserted cells are spaced with respect to one another by spacers, whereby this clearance becomes available as a bypass duct, strips being arranged in the bypass ducts which project away from the spacer.

Battery container for several electrochemical accumulators arranged

The invention relates to a battery box having a plurality of orientation-independent electrochemical cells. Within the battery box, the cells are arranged horizontally, cells which are located one above the other being combined to form a cell group having flow channels arranged between adjacent cells. The flow channels of a cell group are connected via a transverse inlet flow channel to a distributor channel and via a transverse outlet flow channel to a collecting channel, the collecting channel being arranged with respect to the battery box on the side opposite the distributor channel.

Battery box with fluid flow channels to maintain proper temperature

An electrochemical storage device having a metallic, gas-tight storage device housing in which an electrode stack formed from a plurality of electrode plates stacked on one another is accommodated. Arranged between the storage device housing and the electrode stack is a box-like stack insulation which is made from an electrically insulating material and which surrounds the electrode stack on the sides which come to bear directly against the housing interior. For the purpose of reliable flow of the quantity of gas occurring during operation, there are arranged on those circumferential sides of the stack insulation towards which the narrow sides of the electrode plates point material protuberances which cross over the narrow sides of the electrode plates and which are spaced apart from one another in order to form gas conduits.

Electrochemical storage device

A battery box for a plurality of electrochemical cells which are arranged in rows one behind the other, a circulating-flow channel being formed by a spacing of the cells from one another within each row, through which a fluid can flow. The circulating-flow channels are all fluidically connected to an inlet channel which tapers in the flow direction and is arranged in the vicinity of the box bottom, and to an outlet channel which expands in the flow direction and is arranged in the vicinity of the box lid. To secure the individual cells, the side walls are provided, in the vicinity of the box bottom, with step-type ledges on which the cells are arranged in a vertically staggered manner in the vicinity of their bottom side edges. The slope of the ledges corresponds in magnitude and direction to the taper of the inlet channel on the bottom side, and the width of a step of the ledge corresponds to the depth of the housing of a cell, plus the corresponding clearance of the circulating-flow channel.

Battery box with a circulating flow channel

A centrifugal coupling with fly elements pressable against the internal surface of a friction drum contact to spring biasing forces wherein the fly elements each include at least two concentric partial weights mutually connected by radially-acting compression springs. The radial stroke of the inner partial weight or weights is limited by a primary side stop, so that from a specific predetermined speed any further increase in the centrifugal force from the inner partial weight directly acting upon the outer partial weight is prevented. The partial weights are further provided with check ramps, inclined in the circumferential direction, for a driver pin mounted on the primary side in order to give the torque curve of the coupling an optimum configuration. In some embodiments the check ramp on the outer partial weight may be replaced by a lever mounted on the primary side which transforms the force generated by the inner partial weight into a centripetal force acting upon the outer partial weight.
