Abstract
The utility model belongs to electric automobile field, relates to a kind of battery case, and this battery case box house is divided into supplying air bin, battery compartment and wind chamber; Supplying air bin is provided with battery case air inlet, and wind chamber is provided with battery case air outlet.This battery case has the advantage of good heat dissipation effect.
Description
Technical field
The utility model relates to a kind of casing, particularly relates to the battery case that a kind of electric automobile uses.
Background technology
Electric automobile, owing to having the features such as zero discharge, noise be little, is more and more subject to the attention of countries in the world.Battery is the power producer of electric automobile, there is chemical reaction due to inside in battery in car running process, amount of heat can be released, thus own temperature is raised, if be in serviceability and life-span that the condition of high temperature can have a strong impact on battery for a long time, therefore, whether electric automobile has a good battery heat removal system is the key factor affecting its performance.
Because batteries of electric automobile group is made up of multiple battery module connection in series-parallel, existing heat sink conception often occur that battery module air outlet discharges distinguished and admirable enter the phenomenon of next module, owing to absorbing partial heat in last module, therefore after entering, the wind-warm syndrome of a module can be higher, heat-sinking capability reduces greatly, also can pass through from module and the gap of module and module and battery case by some air quantity, the utilance of reduction air quantity simultaneously.
Utility model content
In order to improve battery radiating effect, the utility model provides a kind of battery case.
The utility model solves the technical scheme that its technical problem adopts: battery case, box house is divided into supplying air bin, battery compartment and wind chamber, and supplying air bin is provided with battery case air inlet, and wind chamber is provided with battery case air outlet.
Dividing plate is provided with between supplying air bin and battery compartment, between battery compartment and wind chamber, the dividing plate of supplying air bin and battery compartment has ventilating opening in the position of corresponding battery module air inlet, and the dividing plate of battery compartment and wind chamber has ventilating opening in the position of corresponding battery module air outlet; Can not dividing plate be established between storehouse and storehouse, between battery module and between battery module and battery bulkhead, be provided with hermetically-sealed construction, make the wind of supplying air bin can not walk around battery module and arrive wind chamber.
Multiple battery module is fixed in battery compartment, and the heat dissipation wind channel of each battery module is directly communicated with wind chamber with supplying air bin, does not form series connection each other.
The utility model has following beneficial effect and advantage: because supplying air bin and battery compartment, ventilating opening without other except the heat dissipation wind channel of battery module between battery compartment with wind chamber are communicated with, and the heat dissipation wind channel of each battery module is not connected each other, ensure that the wind entered from battery case air inlet only enters battery module from battery module air inlet, the wind flowed out from battery module air outlet is directly discharged from battery case air outlet, the situation of intersecting and dispelling the heat can not be produced, and the utilance of air quantity can be improved.

Embodiment
The utility model is described preferred embodiment below in conjunction with accompanying drawing 1-3.
Battery case of the present utility model, is made up of front side board 1, back side panel 8, left plate 3, right plate 6, front apron 5, backboard 7 and top board 2 and base plate 4.Form a casing by top board 2, base plate 4 and four side plates, front side board 1 provides battery case air inlet 9, and left plate 3 and right plate 6 provide battery case air outlet 13.Casing internal fixtion has front apron 5 and backboard 7, supplying air bin 10 is surrounded by front side board 1, left plate 3, right plate 6, top board 2, base plate 4 and front apron 5, surround battery compartment 12 by front apron 5, left plate 3, right plate 6, top board 2, base plate 4 and backboard 7, surround wind chamber 14 by backboard 7, left plate 3, right plate 6, top board 2, base plate 4 and back side panel 8.Front apron 5 only has ventilating opening in the position of corresponding battery module 11 air inlet, and backboard 7 only has ventilating opening in the position of corresponding battery module 11 air outlet.Multiple battery module 11 is fixed in battery compartment, and the heat dissipation wind channel of each battery module 11 is directly communicated with wind chamber 14 with supplying air bin 10, and does not form series connection each other.Owing to there being the existence of ventilating opening on front apron 5, backboard 7 and baffle plate, therefore it is inner that the wind that battery case air inlet 9 enters only enters battery module 11 from the air inlet of battery module 11, the wind of battery module 11 air outlet discharge is also direct discharges from battery case air outlet 13, again can not enter other battery modules 11, both ensured to produce the situation of intersecting and dispelling the heat, in turn ensure that effective utilization of air quantity.
The foregoing is only the utility model preferred embodiment; not thereby the scope of the claims of the present utility model is limited; every equivalent structure transformation utilizing the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
