Description
Technical field:
The utility model relates to the lithium battery module of electric vehicle power supply, particularly a kind of efficient heat conduction structure.
Background technology:
Constantly in short supply along with primary energy, the research of electric automobile has all been carried out in countries in the world, and its thinking adopts powerful lithium battery group or module as dynamical system exactly, all or part of replacement fuel engines.At present, common lithium battery module is to adopt the external coupling type circuit that a plurality of single lithium battery that are arranged side by side are carried out being encapsulated in the U-shaped housing after the connection in series-parallel, and respectively is provided with one in the front and back of U-shaped shell two open side and is used for dispelling the heat with the mutually bonding heating panel of cell front/rear end.The shortcoming of this structure is: 1, can realize well fixing by strengthening gluing being connected together between single lithium battery and the heating panel, but also be unfavorable for the dismounting maintenance simultaneously, in case wherein damaging appears in certain single lithium battery, just must change the entire cell module, thereby cause serious waste; 2, the packaging technology assembled side by side of the bending technique of aluminium box and a plurality of single lithium battery causes each aluminium box front/rear end out-of-flatness easily, causing aluminium box and heating panel to form point contacts and increases thermal resistance, influence the radiating effect of battery module, stay potential safety hazard for the normal use of battery module.
The utility model content:
Goal of the invention of the present utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of good heat dissipation effect is provided and is convenient to dismantle lithium battery module with repair and replacement.
In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme:
A kind of lithium battery module of efficient heat conduction structure, comprise U-shaped housing, front and back heating panel and be arranged side by side a plurality of single lithium battery in described U-shaped housing, respectively be provided with a heat conductive silica gel between the front/rear end of described front and back heating panel and the described single lithium battery that is arranged side by side, the inner surface of described heat conductive silica gel and the front/rear end of single lithium battery fit, and the inner surface of the outer surface of described heat conductive silica gel and front and back heating panel fits.
Described single lithium battery comprises the aluminium box and is installed in the interior battery of aluminium box, described aluminium box is spirally connected by two blocks of aluminium sheets that are provided with flanging and forms, wherein be fixed with outward extending threaded on the flanging of an aluminium sheet, have the pin-and-hole that passes for described threaded on the flanging of another piece aluminium sheet.
Be respectively equipped with the through hole that passes for described threaded on described front and back heating panel and two heat conductive silica gels, the outer end of described threaded is provided with locking nut.
Described front and back heating panel is aluminium sheet or aluminium alloy plate.
The utility model has been owing to adopted above technical scheme, thereby has following advantage with respect to prior art:
1, between aluminium box front/rear end and front and back heating panel, respectively paste the lastblock heat conductive silica gel, the aluminium box front/rear end out-of-flatness that causes with the bending technique of avoiding the aluminium box and each single lithium battery packaging technology, contact the thermal resistance increase phenomenon of being brought with heating panel formation point and solve the aluminium box, make this battery module have more superior radiating effect, and then the fail safe that can prolong the useful life of battery module and guarantee to use.
2, fix by threaded and locking nut between single lithium battery and heat conductive silica gel and the heating panel, be convenient to the dismounting maintenance of each single lithium battery, in case certain single lithium battery inefficacy or damage occur, be to reload again after available new single lithium battery is in time changed or this dismounting battery keeped in repair, thereby need not to change the entire cell module, saved a large amount of replacings and maintenance cost.
Description of drawings:
Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the plan structure schematic diagram of the utility model lithium battery module;
Fig. 2 is the structural representation of single lithium battery in the utility model.
Embodiment:
See figures.1.and.2, the lithium battery module of the efficient heat conduction structure that provides according to the utility model, comprise U-shaped housing 1, front and back heating panel 2,3 and be arranged side by side a plurality of single lithium battery 4 in U-shaped housing 1, front and back heating panel 2,3 is aluminium sheet or aluminium alloy plate, have good heat dissipation characteristics, respectively be provided with a heat conductive silica gel 5 between the front/rear end of front and back heating panel 2,3 and the single lithium battery 4 that is arranged side by side.The front/rear end of the inner surface of heat conductive silica gel 5 and single lithium battery 4 fits, the inner surface of the outer surface of heat conductive silica gel 5 and front and back heating panel 2,3 fits, the surfaces externally and internally that is heat conductive silica gel 5 contacts with single lithium battery 4 formation faces with front and back heating panel 2,3 respectively, thereby can avoid a thermal resistance that contact is brought to increase phenomenon.
Described single lithium battery 4 comprises aluminium box 41 and is installed in battery 42 in the aluminium box 41, aluminium box 41 is spirally connected by two blocks of aluminium sheets 44,45 that are provided with flanging 48,43 and forms, wherein be fixed with outward extending threaded 46 on the flanging 48 of an aluminium sheet 44, have the pin-and-hole 47 that passes for threaded 46 on the flanging 43 of another piece aluminium sheet 45.Be respectively equipped with the through hole 6,7 that passes for threaded 46 on 2,3 and two heat conductive silica gels 5 of front and back heating panel, the outer end of threaded 46 is provided with locking nut 8.During installation, threaded 46 screws on locking nut 8 after passing through hole 6,7 again, just single lithium battery 4, front and back heating panel and heat conductive silica gel 5 can be fixed together, and then also only needs to screw out locking nut 8 during dismounting and gets final product, and is very convenient.
