It is surrounded by bottom plate and four side plates facing each other, positioning is symmetrically provided on the inner wall of the opposite side plate of one of which
Slot, head cover 22 are used to surround each gap with 21 fitted seal of lower box.It is this that atrium is surrounded on bottom plate by four side plates
Lower box 21, it is simple in structure, convenient for make.
Further, single battery can be equal to by being provided with the distance between one group of opposite inner wall of side wall of locating slot
1 length, the width that can also be equal to single battery 1 are provided with one group of opposite side of locating slot in embodiments of the present invention
The distance between inner wall of wall is equal to the length of single battery 1, and so, the contact area of single battery 1 and heat-conducting layer is more
Greatly, heat dissipation effect is more preferable.
Above-mentioned 2 structure of battery case is a kind of preferred embodiment provided by the invention, can also use others
Structure can be arranged multiple vertical for example, in the contact of above-mentioned lower box 21 in the atrium that bottom plate and four side plates surround
The partition board of traversed by fork can be depending on actual demand, here as long as the support and protection to battery modules can be realized
No longer illustrate one by one.
There would generally be more than two single batteries 1 in battery modules, the position relationship between single battery 1 will be straight
The connection influenced between each single battery 1 is connect, therefore, in embodiments of the present invention, is implemented referring to Fig. 3, Fig. 3 is the present invention
The structural schematic diagram of single battery and lower box cooperation in the battery modules that example provides, battery modules include multiple single batteries 1,
It is corresponding, multiple locating slots are both provided on the opposite side plate of the one of which of lower box 21, multiple single batteries 1 are parallel
Ground is set in lower box 21, and the gap between adjacent two single battery 1 is the first joint filling 4, single battery 1 and lower box 21
Gap between the inner wall of another group of opposite side plate is the second joint filling 5.It can be seen that above-mentioned lower box 21 not only self structure
Simply, it is convenient for manufacture, and can be by neat arranged in parallel of multiple single batteries 1, consequently facilitating cabling, and keeps cabling clear
It is clear, facilitate inspection.
Since heat-conducting layer in the battery modules course of work, may be changed due to heated made of phase-change material
Become own shape, for example become liquid from solid-state, therefore, the effect of head cover 22 is mainly to the lower box equipped with single battery 1
Each gap at 21 top is blocked, and to prevent heat-conducting layer to be lost in, influences heat dissipation effect, it is well known that two kinds of differences
The interface of material can have thermal contact resistance, influence the transmission efficiency of heat, to solve the above-mentioned problems, please refer to Fig. 4 and figure
5, Fig. 4 be the heat conduction needle sealing cover structure schematic diagram in the head cover of battery modules provided in an embodiment of the present invention；Fig. 5 is the present invention
Side seals lid 22a structural schematic diagrams in the head cover 22 for the battery modules that embodiment provides, head cover 22 include for blocking the
The heat conduction needle sealing cover 22b of one joint filling 4 and side seals lid 22a, heat conduction needle sealing cover 22b for blocking the second joint filling 5
Including cover board 7, heat conduction needle 6 and the first radiating fin 8, heat conduction needle 6 and the first radiating fin 8 are divided into following table on cover board 7
On face, heat conduction needle 6 is for being inserted into the heat-conducting layer in the first joint filling 4, referring to Fig. 6, Fig. 6 is electricity provided in an embodiment of the present invention
The structural schematic diagram of the heat conduction needle sealing cover of pond module and lower box assembly, the insertion of heat conduction needle 6 on heat conduction needle sealing cover 22b are led
Thermosphere can increase the contact area between heat conduction needle sealing cover 22b and heat-conducting layer, improve the conduction efficiency of heat, and be set to
First radiating fin 8 of the other sides heat conduction needle sealing cover 22b, can further increase radiating efficiency.
In order to advanced optimize above-mentioned technical proposal, in embodiments of the present invention, the outer wall of four side plates of lower box 21
On be both provided with the second radiating fin 3, the second radiating fin 3 can both be structure as a whole with lower box 21, can also be used as one
A independent accessory is removably mounted on lower box 21.
Locating slot plays the role of the fixation of single battery 1 vital, and single battery 1 can be prevented in battery
Module topples over extruding heat-conducting layer when running, in embodiments of the present invention, the opposite side plate of one of which of lower box 21
At least two positioning ribs are both provided on inner wall, the inner wall of side plate surrounds locating slot with two positioning ribs thereon.It is above-mentioned by fixed
Position rib constitutes the mode of locating slot with side plate inner wall, simple in structure, convenient for making, and can be played to single battery 1 good
Fixed function.
If making contacts baseplate of the bottom of single battery 1 directly with lower box 21, cause single battery 1 bottom and its
He is different with the position radiating efficiency of heat-conducting layer contact, eventually results in single battery 1 internal temperature unevenness, influences to use the longevity
Life, therefore, in order to solve the above-mentioned technical problem, in embodiments of the present invention, locating slot is from the opening of lower box 21 to bottom plate
Direction extends, and the length of locating slot is less than the height of lower box 21, and so, single battery 1 is inserted into bottom along locating slot
Afterwards, it can also be filled and lead in this gap there are certain gap between the bottom of single battery 1 and the bottom plate of lower box 21
Thermosphere, so that 1 Homogeneouslly-radiating of single battery, extends its service life.
For further above-mentioned technical proposal, in embodiments of the present invention, it is provided on the inner wall of the bottom plate of lower box 21
Height is no more than the heating column of locating slot lower edge, and above-mentioned locating slot lower edge is locating slot near the side of 21 bottom plate of lower box
Edge is dissipated in this way, heating column can not only increase the contact area of the heat-conducting layer and bottom plate that are filled in 21 bottom of lower box with improving
The thermal efficiency, additionally it is possible to play the role of skeleton, the heat-conducting layer of 21 bottom of support lower box extends its service life.
In order to further reinforce the heat dissipation effect of battery modules, in embodiments of the present invention, battery modules further include control
