Have: two ports 311 are respectively used to flowing in and out for cooling medium, and the heat that thermally conductive upper cover plate 2 is transferred to coldplate 3 exists
Flowing in and out for cooling medium is pulled away in the process, so as to which each battery 11 temperature in use is effectively reduced.
With further reference to Fig. 7, cooling pipe 31 can be arranged in coldplate 3 with serpentine path, but be not limited only to this kind of cloth
Set form.Here, coldplate 3 is fixedly connected by welding again after can sandwiching cooling pipe 31 by upper layer and lower layer plate.
Referring to Fig. 4, thermally conductive upper cover plate 2 is settable, and there are two through-holes 21.Referring to figs. 1 to Fig. 3, battery modules may also include that
Two output stage terminals 4, each output stage terminal 4 are electrically connected to cell assembly 1, wear and stretch out the correspondence of thermally conductive upper cover plate 2
One through-hole 21.Coldplate 3 is fixedly installed on the top of the part between two output stage terminals 4 of thermally conductive upper cover plate 2.
Wherein, in order not to additionally increase the volumes of battery modules, the volume energy density of battery modules, coldplate 3 are promoted
Output stage terminal 4 can be shared and stretch out the occupied height of thermally conductive upper cover plate 2, is i.e. the thickness of coldplate 3 can be not more than output stage
Terminal 4 stretches out the height of thermally conductive upper cover plate 2.
