Definitions
- the invention relates to a device for electrical energy storage according to the preamble of claim 1.
- electrochemical energy storage units of high power density are known.
- these are lithium-ion batteries. It is also well known to flow such high-performance batteries with air, for example, from an air-conditioned passenger area or directly from an air conditioner to cool and so.
- US Pat. No. 6,821,671 B2 describes a cooling arrangement for cooling prismatic batteries.
- heat-conducting cooling plates are inserted between the flat cells. At their lateral end, the plates have cooling ribs in order to dissipate the heat to a fluid.
- Advantageous embodiments are the subject of the subclaims.
- a stacking of the individual flat cells to at least a first stack, wherein between adjacent flat cells of the first stack each have a cooling element made of good heat conducting material is carried out.
- the individual cooling elements are larger in area than the flat side of a flat cell, so that laterally spaced from the flat cell, the cooling element has a region which is not covered by a flat cell.
- the cooling elements at least an opening into which a heat-transmitting member is inserted to dissipate the heat generated in the flat cells to a fluid flowing in the heat-transmitting member.
- a first and a second stack are formed by the flat cells.
- the same cooling element is arranged both between adjacent flat cells of the first and the second stack.
- the individual cooling elements are larger in area than two flat sides of a flat cell, so that a gap is created between the first and second stack.
- the cooling elements In this area, which corresponds approximately to the middle of the cooling element, the cooling elements have at least one opening into which a heat-transmitting element is inserted.
- the cooling element may have at the lateral edges further openings for heat-transmitting elements in order to allow a higher heat dissipation to a cooling fluid flowing in the heat-transferring elements.
- the same cooling element is arranged between adjacent flat cells of these multiple stacks.
- a cooling element is arranged after every second flat cell.
- the cooling element is advantageously made of a metal, in particular of the group aluminum, copper or aluminum with rolled-on copper, and is preferably designed as a cost-effective sheet-metal shaped part.
- the cooling plates preferably have a rectangular shape and may additionally be angled on at least one side in order to form a kind of receptacle for the flat cells.
- two cooling plates, which are angled at the respective ends form a cassette, in which the flat cell is inserted.
- two cooling plates are arranged between adjacent flat cells.
- the thickness of the cooling element is preferably 0.2 to 2 mm, but it can be greater than 2 mm with increased cooling capacity.
- the heat-transmitting element is particularly preferably designed as a pipe fork.
- a pipe fork at least two, but preferably four, six or even a plurality of openings are provided in the sheet metal, in which the pipe forks are inserted.
- individual pipes may also be inserted into the openings, the pipes being communicatively connected at their respective ends, similar to an evaporator, to a collector through which the fluid is distributed to the individual pipes.
- the pipe forks or pipes are at least positively or frictionally connected by expansion with the cooling plates.
- the openings may be provided with a passage to facilitate the insertion of the pipe forks and to represent a sufficiently large contact area between the pipe wall and the cooling plate.
- the diameter of the pipe forks is preferably between 4 and 10 mm.
- the passages are preferably formed on the cooling plates, alternatively soldered. Through the pipes, the mechanical bond and the strain of the cell network are shown.
- a fluid in particular a refrigerant or a coolant, for example a mixture of water and glysantin.
- the pipe forks are connected in a preferred embodiment communicating with a refrigeration cycle of a motor vehicle air conditioning. Alternatively, however, they may also be part of a self-sufficient circuit, which is preferably thermally coupled to the refrigeration cycle of a motor vehicle air conditioning system.
- a compressible material preferably a fleece
- the fleece is inserted between the flat cells and serves for tolerance compensation.
- the individual stacks can additionally be braced by metal bands and arranged in a housing, for example made of plastic.
- FIG. 1 shows a device for electrical energy storage according to the present invention
- FIG. 5 shows a cooling element with a passage for a heat-transmitting element
- Fig. 1 shows an apparatus for electrical energy storage 1 according to the present invention.
- Such an energy storage unit comprises a plurality of flat cells 2, for example lithium-ion flat cells, which are stacked one above the other with their flat sides 10 and form a cell stack.
- the flat side of the flat cell 2 is understood to mean the side with the larger surface which directly or indirectly adjoins a flat side of an adjacent flat cell 2.
- the flat cells and the cooling plates 5 arranged between adjacent flat cells form a first 3 and a second 4 cell stack, each stack having an equal number of flat cells.
- the individual flat cells are still sorted thick before stacking to provide for a corresponding tolerance compensation.
- the same cooling plate 5 serves both for dissipating heat from flat cells of the first 3 and flat cells of the second stack 4.
- a further cooling plate 5 is arranged at least at one end of the first and second stack.
- four flat cells two each on one side of the cooling plate, are fastened, preferably glued, onto a cooling plate 5 so that in the stacking direction a cooling plate follows after every second flat cell. If the resulting waste heat of the flat cells is too large, a cooling plate may alternatively be arranged between each flat cell.
- the heatsinks are made of highly thermally conductive material such as aluminum, copper, an aluminum-containing alloy or aluminum with rolled copper.
- the sheets are rectangular and preferably have a thickness between 0.2 and 2 mm.
- the cooling plates each have six openings (see FIG. 2), into which three pipe forks are inserted, which extend through the entire cell assembly consisting of the first and second stacks.
- the pipe forks also consist of a good heat-conducting material and are positively and frictionally connected with the cooling plates chen, which is achieved by a mechanical or hydraulic expansion.
- the open ends of the pipe forks 7 are communicatively connected, for example, welded and subsequently connected to a refrigeration cycle or a cooling circuit.
- a fluid for example a refrigerant or a coolant, for example a water-glysantin mixture.
- the flat cells each have two arresters (electrical cell connections) 11 on their narrow sides, which are electrically connected in a manner not shown. be clocked to ensure a parallel or in particular serial shading of the individual flat cells.
- FIGS. 3 and 4 show two further exemplary embodiments of a cooling plate 5.
- a cooling plate 5 in each case, six further openings are formed on the lateral edges in addition to the six openings in the middle region of the cooling plate, the number of openings being not meant to be limiting.
- the cooling plate 5 only has openings on a lateral edge.
- Such a cooling plate 5 is preferably suitable for forming a stack.
- the area of a cooling plate is larger than the area of the flat side of a flat cell. This creates an area in which the openings 6 are arranged.
- Fig. 5 shows a further alternative embodiment of a cooling plate according to the invention.
- the cooling plates 5 are provided with passages 9, which are preferably integrally formed on the cooling plate.
- a compressible material 8 for example a fleece, a woven fabric or a felt mat is arranged between the flat cells 2 of the first 3 and second stack 4.
- the compressible material is used to compensate for tolerances and the mechanical stress for thermal contacting and preferably has a thickness of 0.5 to 2 mm.
- the compressible material can only be inserted between the flat cells or glued together with them.
- a fleece is arranged after every second, in FIGS. 7a and 8 a fleece after each flat cell.
- FIGS. 6 to 8 are, of course, also conceivable without compressible material 8.
