Drawings
The above and other objects and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which like or similar elements are designated by like reference numerals.
Fig. 1 schematically illustrates an exploded perspective view of a battery module body according to the present disclosure; and
fig. 2 exemplarily shows a bottom view of the battery module body according to the present disclosure.
Detailed Description
Fig. 1 schematically illustrates a battery module 10 according to the present disclosure. As can be seen from fig. 1, the battery module body 10 includes a battery module 1, a cooling unit 3, and a connecting mechanism 4 that connects the battery module 1 and the cooling unit 3 together. Alternatively, a cementing mechanism may be provided to connect the battery module 1 and the cooling unit 3 together. Here, the cementing mechanism may be disposed between the battery module 1 and the cooling unit 3. Preferably, the adhesive mechanism includes a thermally conductive adhesive, and the cured viscosity of the thermally conductive adhesive can connect the cooling unit 3 and the battery module 1 together. And the heat-conducting glue can conduct the heat of the battery module 1 to the cooling unit 3 better, so that the cooling effect of the battery module 1 is optimized.
As can be seen from fig. 1, the connecting mechanism 4 includes a first element 41 and a second element 42 cooperating with the first element, wherein the first element 41 is fixed at the battery module 1, and the second element 42 cooperates with the first element 41 to fix the cooling unit 3 at the battery module 1.
Alternatively, as shown in fig. 1, the cooling unit 3 may comprise at least one cooling plate.
Alternatively, the connection 4 can be designed as a screw connection. Illustratively, the first element is a bolt 41 and the second element that cooperates therewith is a nut 42. In this case, the bolts 41 of the screw connection 4 are preferably welded or riveted to the battery module 1. Specifically, the bolts 41 may be welded to the brackets of the battery module 1 as shown in fig. 1 in conjunction with fig. 2 or may be riveted to the battery module 1.
As can also be seen from fig. 1, the cooling plate of the cooling unit 3 is formed with a passage through which the screw 42 can be engaged, and the screw is screwed through the passage and the nut 42 of the screw connection 4, so that the cooling plate is fixedly screwed to the battery module 1.
Preferably, as shown in fig. 1, the battery module body 10 further includes a heat conductor 3, and the heat conductor 3 is disposed between the battery module 1 and the cooling unit 3 to more efficiently conduct heat of the battery module 1 to a cooling plate. Alternatively, the heat conductor 3 may be configured as a heat conducting mat, but of course may be configured in other configurations to fill the gap between the cooling plate and the module.
Preferably, in the battery module body 10 disclosed in the present application, one cooling unit 3 is allocated to each of the battery modules 1, and this single-module single-plate cooling manner can more effectively cool the battery modules 1.
The present application also discloses a battery pack including the battery module 10 described in any of the above embodiments.
