Definitions
- the invention relates to a temperature control device with individual battery cells assembled to form a module, which are arranged within a flow channel through which a temperature control fluid flows in a main flow direction.
- Temperature control devices for battery modules of different designs are known from the prior art, in which individual battery cells are arranged within a flow channel (DE102015013377A1).
- a temperature control fluid flows through the flow channel in a main flow direction from a group of first fluid connections to a group of second fluid connections.
- This problem is exacerbated with particularly dense packing of the battery cells, because then even small dead volumes are sufficient to make an efficient flow around the battery cells and thus a highly dynamic temperature control with, at the same time, small amounts of temperature control fluid impossible.
- it is essential for a long service life of the battery cells it is important to operate them in a low temperature range and to allow only small temperature spreads within a battery module.
- the invention achieves the stated object in that for each battery cell of a group a flow guide surface is provided which is spaced apart from a jacket section of the battery cell and which has an inlet and outlet section that is essentially parallel to the jacket section and that between the inlet and outlet section a facing these and the jacket section Recessed diffuser section is arranged.
- the invention is based on the knowledge that when the flow around the battery cells is known from the prior art, only a punctual and short-term cooling effect occurs without a complete heat exchange between the temperature control fluid and the battery cells being able to take place.
- the flow guide surfaces of adjacent battery cells form a flow divider.
- the flow divider occupies the space between the adjacent battery cells with the exception of the guide channels resulting between the flow guide surfaces and the battery cells, so that the otherwise existing dead volume can be reduced.
- an arrangement of the individual battery cells in the form of a very close circular packing thus results in flow dividers with an approximately star-shaped cross section with three jets.
- Tests have shown that the ventilation behavior of the flow channel can be improved by a group of flow dividers forming a further flow guide surface which runs essentially parallel to the inner wall of the flow channel.
- At least one group of flow dividers 7 has flow guide surfaces 8 which run essentially parallel to a jacket section 9 of the battery cells 2.
- These flow guide surfaces 8 have an inlet section 10 or outlet section 11, both of which are arranged at the same distance, i.e. normal distance from the jacket section 9.
- a diffuser section 12 whose distance from the jacket section 9 is 5 to 30% greater than the distance from this jacket section 9 to the inlet section 10 or to the outlet section 11.
- the fluid connections 4, 5 on the opposite edge sections ensure more homogeneous flow conditions when the temperature control fluid enters the flow channel 3.
- the cross section of these fluid connections 4, 5 is oval and flattened in the main flow direction 6.
- the available space is optimally used and, on the other hand, turbulence in the inflow and outflow area is minimized.
- flow guide elements 16 are provided, each of which has a flow guide surface 17 that is convex towards the fluid connection 4, 5 as a flow resistance and serves as a flow divider.
