Detailed description of the invention
Below by specific embodiment and combine accompanying drawing the application is described in further detail.Need explanation
It is that " thickness direction ", " short transverse " hereinafter is all with state shown in scheming as reference.
As shown in Fig. 1-17, the embodiment of the present application provides a kind of battery component, and it includes battery 10 and fixed support 20,
Battery 10 can be installed on fixed support 20 by double faced adhesive tape or structure glue etc..This fixed support 20 can include framework 200
With heat sink 201, framework 200 and the one-body molded setting of heat sink 201, heat sink 201 includes being positioned at first within framework 200
Part 201a, and the Part II 201b exposed relative to framework 200, this Part I 201a fixes with Part II 201b
Connecting, Part II 201b extends along the thickness direction of battery 10.
In above-mentioned battery component, framework 200 and the one-body molded setting of heat sink 201, this kind of set-up mode can avoid frame
After there is rigging error between frame 200 and heat sink 201, the problem that the radiating effect that causes is undesirable.Therefore, this set of cells
The radiating effect of part is more preferable.Meanwhile, framework 200 and the integrated set-up mode of heat sink 201, it is also possible to better ensure that solid
The bulk strength of fixed rack 20.And the Part II 201b of heat sink 201 exposes, therefore can by this Part II 201b more
Well heat is shed, equally promote the radiating effect of battery component.
It addition, use above-mentioned be wholely set mode after, owing to the structural strength of fixed support 20 is greatly increased, therefore
After battery modules assembling, the thermal interface between fixed support 20 and other parts has bigger intensity and planarization, also
Ensure that effective heat radiation of whole battery component.
Generally, framework 200 uses plastic material, heat sink 201 can use aluminium sheet.When manufacturing framework 200, in order to just
In the injection mo(u)lding of framework 200, simultaneously facilitate the fixing of heat sink 201 and sealing, following setting can be used: on framework 200
The outer surface extended along the thickness direction of battery 10 is heat radiation contact surface, this heat radiation contact surface is offered groove 200a, this groove
200a extends at Part II 201b, i.e. it is hatch frame that groove 200a extends to the side of Part II 201b.Further
Ground, groove 200a extends along the joint of Part II 201b with heat radiation contact surface, and the opposite end of groove 200a all passes through
Pass to the edge of heat radiation contact surface.Now, groove 200a is U-lag, increases the active area of groove 200a, and then strengthening with this
Aforesaid technique effect.
In order to ensure heat sink 201 can reliably with other part contact with realize heat radiation, at the height of battery component
On direction, Part II 201b is higher than the heat radiation contact surface of framework 200.After adopting the structure, heat sink 201 is relative to framework
200 protrude, and not only contribute to determine heat sink 201 and other parts whether reliable contacts, it is also possible to by controlling heat sink 201
And the active force between other parts, preferably ensures the area of dissipation of heat sink 201.
Above-mentioned heat sink 201 could be arranged to one, it is also possible to is set to multiple, heat sink 201 is set to multiple after,
Each heat sink 201 can provide bigger area of dissipation, and then strengthening radiating effect.When heat sink 201 is set to multiple, respectively
In heat sink 201, the Part I 201a phase of the Part I 201a of one of them heat sink 201 and another heat sink 201
Contact, the Part II 201b of one of them heat sink 201 aforesaid and the Part II 201b of another heat sink 201 along
Contrary direction extends.
Such as, as is seen in figs 7-10, heat sink 201 could be arranged to two, and the two heat sink 201 is respectively first and dissipates
The Part I 201a of hot plate 201c and the second heat sink 201d, the first heat sink 201c and first of the second heat sink 201d
Dividing 201a to contact, the Part II 201b of the Part II 201b and the second heat sink 201d of the first heat sink 201c is along phase
Anti-direction extends.It is to say, when heat sink 201 is set to multiple, each heat sink 201 entirety can be divided into two groups, and these are two years old
The group opposing liftoff setting of heat sink 201 so that each heat sink 201 can be compactly installed in framework 200.
Further, in above-mentioned each heat sink 201, the Part I of one of them heat sink 201 includes the first protuberance,
The Part I of another heat sink 201 includes the second protuberance, the protrusion direction of this first protuberance and the second protuberance
Protrusion direction is contrary.The first protuberance and the second protuberance herein can apply active force to battery, realize battery with this
Pre-fix, and then strengthen the structural strength of battery modules.Specifically, after the installation of each heat sink 201, the first protuberance and
Two protuberances can fit together, it is also possible to does not contacts.When the first protuberance and the second protuberance do not contact, first protrudes
A clearance space will be formed between portion and the second protuberance.Clearance space herein can be that the expansion of battery core provides space, with
The expansive force of this release battery core so that the housing of battery modules is more difficult to be affected by battery core expansive force.
Based on said structure, the embodiment of the present application also provides for a kind of battery modules, and this battery modules includes housing and installation
Multiple battery components in this housing, this battery component is the battery component described by any of the above-described embodiment.
In order to alleviate the heat interference between each battery component, above-mentioned battery modules can also include heat insulating mattress 30, should be every
Heat pad 30 is arranged between adjacent two battery component.It is heat insulation that this heat insulating mattress 30 can use as shown in Figure 14 and Figure 15
Cotton, this heat insulation foam can play the effect of thermal runaway protection, but heat insulation foam is generally of bigger hardness, therefore by heat insulation foam
After being installed between battery component, heat insulation foam itself can occupy bigger space, causes the expansive force of battery modules to increase.In order to
Alleviate this problem, heat insulating mattress 30 can be set to foam as shown in Figure 16 and Figure 17.This foam have easily compressed,
Gently, the advantage such as high temperature resistant.Especially when arranging aforesaid first protuberance or the second protuberance on the heat sink 201 of battery component
Time, the first protuberance or the second protuberance can apply extruding force to foam so that foam produces certain resistance to deformation effect
Power, and then battery is played vibrationproof protective effect.Meanwhile, after there is thermal expansion in battery, applying extruding force further to foam,
And the first protuberance of heat sink 201 or the second protuberance are applied extruding force, the expansive force of release battery modules, with this
The expansive force of limits ground release battery modules, improves the mechanical strength of battery modules.
The foregoing is only the preferred embodiment of the application, be not limited to the application, for the skill of this area
For art personnel, the application can have various modifications and variations.All within spirit herein and principle, that is made any repaiies
Change, equivalent, improvement etc., within should be included in the protection domain of the application.
