Description

A kind of heat dissipation battery bag
Technical field
The utility model relates to a kind of power brick, particularly relates to a kind of electric vehicle heat dissipation battery bag.
Background technology
Electric vehicle battery bag is according to electric motor car load request, by multiple cell or ultracapacitor connection in series-parallel comprising modules, then is made up of the battery pack of certain voltage and capacity multiple module connection in series-parallel, and the box house being placed on a sealing forms power brick.In power brick, battery pack can produce heat in charge and discharge process, if these heats can not distribute in time, gently then can affect the use of battery pack, shortens the life-span of battery pack, heavy what for security incident occurring; When electric automobile uses at low ambient temperatures, because of the poor performance at low temperatures of battery, cause electric motor car normally not use or distance travelled short, charge especially at low temperatures, directly affect the life-span of battery.Power brick heat dissipation technology is a great problem of ev industry, and there are close ties in power brick serviceability and useful life with the working temperature of battery, and therefore power brick heat radiation is a problem that cannot avoid.Power brick seal request and power brick heat radiation for security consideration is the problem of a relative contradiction, although this problem obviously can be improved than the liquid cools radiator structure etc. of higher-end, cost with technically but considerably increase.Therefore, a kind of new technical scheme should be provided to solve the problem.
Utility model content
Based on this, be necessary to provide a kind of structure simple, cost is low, rapid heat dissipation power brick.
The technical solution adopted in the utility model is:
A kind of heat dissipation battery bag, described power brick is by multiple both ends open, the cavity that the aluminum alloy materials of all the other position seals is made is formed by connecting, the shape and size of described cavity and the shape and size of columniform battery suitable, battery is positioned in described cavity, and the bottom of described power brick is evenly equipped with fin.
Further technical scheme:
Multiple described power brick clamping forms battery package, and the gap between adjacent cell bag forms ventilation hole.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, heat dissipation battery bag of the present utility model solves the problem of high cost that conventional batteries bag adopts high-end liquid cools radiator structure to bring and high technology content, and structure is simple, and cost is low.
2, heat dissipation battery bag of the present utility model, employing aluminum alloy materials makes the cavity for putting battery, and aluminium alloy has the high performance of heat conduction efficiency, can improve the heat dispersion of the utility model power brick.
3, heat dissipation battery bag of the present utility model, when many Battery packs bag is connected together formation battery package, gap between adjacent power brick defines ventilation hole, and the bottom of design power brick is covered with fin, above rational radiator structure further improves the heat dispersion of power brick.

Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is accompanying drawing 1 sectional view.
Accompanying drawing 3 is battery pack structure schematic diagram.
Accompanying drawing 4 is accompanying drawing 3 sectional view.
In above accompanying drawing: 1, cavity, 2, battery package, 3, fin, 4, ventilation hole.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one:
As illustrated in fig. 1 and 2, a kind of heat dissipation battery bag of the utility model, described power brick is by multiple both ends open, the cavity 1 that the aluminum alloy materials of all the other position seals is made is formed by connecting, the shape and size of described cavity 1 and the shape and size of columniform battery suitable, battery is positioned in described cavity 1, and the bottom of described power brick is evenly equipped with fin 3.Employing aluminum alloy materials makes the cavity 1 for putting battery, aluminium alloy has the high performance of heat conduction efficiency, can improve the heat dispersion of the utility model power brick, the bottom of power brick is evenly equipped with fin 3, further can improve the thermal diffusivity of power brick.
Embodiment two:
As shown in Figures 2 and 4, the mutual clamping of power brick described in many groups embodiment one, a battery package 2 can be formed, gap between adjacent cell bag forms ventilation hole 4, heat just can be distributed by power brick inner vent hole 4 and bottom heat radiation sheet 3 by battery package in use, and structure is simple, and use cost is low, rapid heat dissipation, good heat dissipation effect.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection range of the present utility model.
