Description

ELECTRICAL STORAGE BATTERY The invention relates to an electrical storage battery wherein a heat exchanger is provided between adjacent cells.
Heat is generated in electrochemical energy storage cells, largely as Joule heat in the interior parts of the cells through which charge and discharge currents flow. Such heat can be removed from the cells only via outer surfaces, e.g.
the base, by radiation, convection and heat conduction.
In large energy storage battery, the ratio of surface to volume is so low that all the heat generated in normal charge/discharge operations can be given off only at operating temperatures higher than those beneficial for the service life of the battery. Consequently a limitation of the utilization of the battery (i.e.
by interrupting use with cooling intervals) or a reduced service life have to be accepted.
Large batteries generally comprise up to 50 cells. In such cells a temperature drop of 5 to 10 K may arise between the centre of the battery and its periphery. Temperature differences between the cells arise and consequently cells reach their full-charge state at different times owing to the temperature dependence of the charge acceptance and further processes such as hydrogen evolution or oxygen recombination. With limited charging time, this leads to divergence in the charge state of different cells and, ultimately, after overloading of the undercharged cells, to their premature failure.
There have been a number of proposals for cooling large energy. German Utility Model no. 74 39 582 discloses an arrangement of metal heat conduction plates between individual cells. Preferably, cooling fins which can be cooled by an air stream project outwards from the plates beyond the cells.
German Utility Model no. 88 02 918, discloses leaving separation gaps between individual cells of a storage battery and filling the gaps with expanded copper metal, which has good heat conduction and through which air can pass. German Utility Model no. 90 û2 249, discloses double-walled heat sinks through which a cooling liquid flows and which are in intimate surface contact with the walls of adjacent cells.
However, such cooling bodies i.e. heat conduction plates, expanded copper metal or double-walled heat sinks) frequently lack mechanical resistance to clamping forces of the battery or deformations of the cell walls due to swelling pressure.
An object of the present invention is to provide an electrical storage battery provided with means for removing heat from or supplying heat to cells by heat exchange, such means having adequate resistance to deformation forces as mentioned above and being effective to provide a good rate of heat-exchange.
According to the present, storage battery having a plurality of cells whereof the cell walls are in intimate, heat-conducting contact with a cooling device, characterized in that the cooling device is a two-dimensionally extensive hollow body which has inlets and outlets for a coolant and in which ribs are impressed which extend from both sides substantially perpendicularly to the flow direction and parallel to one another and which form slits inside the hollow body, and in that, at points in each rib corresponding to one another on either side, additional depressions-are provided which meet one another and effect a stabilization of the hollow body.
The hollow body is two-dimensionally extensive, has an inlet and an outlet for a coolant and has ribs impressed in the side walls, which ribs extend substantially perpendicularly to the flow direction and parallel to one another and at the same time form slits inside the hollow body. Additionally, more substantial depressions are introduced at points in each rib which correspond to one another on either side, in such a way that they meet one another and thus stabilize the hollow body with respect to deformations due to external pressure.
The subdivision of the hollow body into a plurality of sub-chambers which communicate with one another only via narrow longitudinal slits achieves a distribution of cooling liquid which is uniform over the entire height of the hollow body, thereby resulting in an equally uniform transverse flow through the hollow body with predominantly horizontal orientation. Such a flowing movement of the coolant, optionally also of a heating liquid, is advantageous and therefore desirable for an intensive heat exchange with the cells.
In a preferred aspect of the invention, the hollow body has an additional rib which first guides the coolant flowing in towards the base of the hollow chamber. From that point, the hollow body is then traversed by the liquid with an inclined upward directional component.
In another preferred aspect of the invention the hollow body instead of or in addition to the channel, deflection ridges are disposed in the hollow chamber in addition to the ribs and are distributed between the latter and extend parallel thereto.
Said hollow-body ribs are generated in a particularly simple manner by longitudinal corrugation of its side walls.
The hollow body may be referred to as a heat sink or a heat exchanger.
Preferably, for material-engineering and production-engineering reasons, the hollow body is a plastics hollow body produced by blow moulding.
It will be appreciated that the coolant is a heat exchange fluid. It is within the scope of the invention to provide such a heat exchange fluid for the purpose of heating, rather than cooling, the cells.
The invention is further described below by way of example with reference to the accompanying drawings, wherein: Figure 1 is a side view of a heat sink according to the invention; Figure 2 is a horizontal cross section of the heat sink shown in Figure 1; Figure 3 is a horizontal cross section, along line A-A of Figure 1, on an enlarged scale of the two leftmost sub-chambers of Figure 1; Figure 4 shows the heat sink of Figure 1, from a narrow side.
Figure 5 shows a coolant inlet of Figure 1, on an enlarged scale; Figure 6 shows the coolant inlet of Figure 5 engaged with a connecting piece; and Figure 7 shows a modification of the heat sink of Figure 1, in an upright projection.
Referring to Figure 1, a heat sink for an electrical storage battery comprises a flat, i.e. two dimensionally extensive hollow, body. The body is formed by two sides which define a chamber constituting the interior space of the body.
The heat sink is disposed between two adjacent cells of an electrical storage battery with the sides of the hollow body in intimate heat-exchange contact with walls of the cells. The hollow body is disposed in a vertical orientation between the two cells.
The hollow body is produced by blow moulding.
Coolant connections 3, specifically a coolant inlet and a coolant outlet are present at the top of the heat sink. The connections are integrally formed with the hollow body when the hollow body is produced by blow moulding.
The coolant connections 3 serve to define a fluid flow path for the coolant through the hollow body.
Each side of the body comprises a wall or web having ribs or longitudinal corrugations 1 which are directed inwardly of the chamber towards the opposite side of the chamber and extend over the full extent of the height of the body. The ribs 1 are all parallel to each other and the ribs of each side are aligned with, i.e. situated opposite, the ribs of the other side whereby the ribs divide the interior of the hollow body, i.e. the chamber, into a plurality of sub-chambers.
The ribs 1 are disposed perpendicularly to the fluid flow path.
Narrow longitudinal slits are defined between facing ribs 1 and provide communication between adjacent sub-chambers.
The slits correspond to the cross-sectional reduction of the original hollow chamber generated by the longitudinal corrugations.
Depressions 2 are present on each rib, the depressions presenting projections on the surface of the rib at the inside of the hollow body. Each projection on either side of the hollow body is in alignment with a corresponding one of the projections on the opposite side of the hollow body and each projection on either side contacts the corresponding, aligned projection on the other side.
Thus the slits are interrupted by the touching projections.
The projections serve to internally strengthen the hollow body by supporting the ribs 1 and thereby the walls of the hollow body. Pressure exerted on the exterior of the hollow body by displacement or bulging of the cell walls is thereby absorbed.
Figure 2 shows that the ribs of one side of the hollow body are opposite i.e.
in alignment with the ribs of the other side of the hollow body and also shows that the ribs define slits or slit-type passages providing communication between adjacent sub chambers.
Figure 3 shows, on its left side, how the ribs 1 provide a slit such as mentioned above where they do not have projections and, at its right, shows how the projections meet to interrupt the slits defined between the ribs.
Preferably the total thickness of the hollow body is 4 mm to 6 mm, preferably approximately 5 mm. Preferably the wall thickness of the hollow body is in the range of 0.5 to 1 mm. Such thicknesses provide both good stability with respect to pressure exerted by the adjacent cells and good heat exchange.
Each connection 3 is, as shown in Figure 5, provided with an inwardly directed sealing surface 4 so that a connecting piece of a coolant flow line, i.e. a coolant inlet line or outlet line, can be inserted into the connection to form a seal by means of a sealing element.
The connecting piece may be an angled piece 6 as shown in Figure 6. The angled piece 6 has an O-ring 7 as sealing element.
The coolant connection may advantageously be provided with an undercut 5 which permits the angled piece 6 to be clipped into the connection while allowing the angled piece 6 to rotate as desired without breaking the seal formed by means of the sealing element 7.
Figure 7 shows a modification of the heat sink shown in Figures 1 to 6.
Referring to Figure 7, the hollow body is provided with an additional rib 8 which is provided in the sub-chamber directly communicating with the inlet connection 3. The rib 8 extends from the top of the hollow body downwardly and terminates short of the bottom of the hollow body. The rib 8 thus serves to guide coolant initially to the base of the hollow body. From there the coolant then rises upwardly at an angle towards the outlet connection, spreading out over the height of the chamber defined by the hollow body and at the same time passing through the slits defined between the ribs.
As an alternative to or in addition to the rib 8 there may be provided deflection ridges 9 which are provided in the sub chambers defined between the ribs 1. Each ridge 9 extends vertically within the hollow body and terminates short of both the top and the bottom of the hollow body. The ridges 9 serve to effect diffuse distribution of the coolant flow over the entire height of the heat sink. In addition they contribute to the dimensional stability of the hollow body with respect to pressure forces to which the sides of the heat sink are exposed.
The ridges 9 may be formed integrally with the hollow body in the course of its production by blow moulding.
The invention may be summarised as follows: 1. Storage battery having a plurality of cells whereof the cell walls are in intimate, heat-conducting contact with a cooling device, characterized in that the cooling device is a two-dimensionally extensive hollow body which has inlets and outlets (3) for a coolant and in which ribs (1) are impressed which extend from both sides substantially perpendicularly to the flow direction and parallel to one another and which form slits inside the hollow body, and in that, at points in each rib corresponding to one another on either side, additional depressions (2) are provided which meet one another and effect a stabilization of the hollow body.
