Technical field
The utility model relates to a kind of cooling device, is specifically related to a kind of battery of electric vehicle air-cooling apparatus.
Background technology
Battery is one of core component of electric automobile and hybrid vehicle, its performance quality directly has influence on the performance of electric automobile and hybrid vehicle, yet be subject to the restriction of technical conditions, the performance of electrokinetic cell is difficult to have in a short time large breakthrough, if make electric automobile obtain commercial applications, just must guarantee that battery works under optimal conditions, to improve its service behaviour, life-saving.The electrokinetic cell bag used on electric automobile is comprised of by series-parallel system a plurality of battery modules, all can produce heat in battery charge and discharge process, thereby make the power brick bulk temperature raise, and can have a strong impact on battery performance and life-span during excess Temperature, even can directly cause battery failure.Simultaneously, while discharging and recharging, in power brick, the heat release in each single pond or the inhomogeneous meeting of dispelling the heat cause in power brick occurring the temperature difference, and the cell degradation that local temperature is higher is very fast, and long-play can destroy the consistency of battery pack, thereby battery pack was lost efficacy.Battery is carried out to effective heat management, make power brick when work, its interior temperature distribution is even, and whole power brick temperature maintains in the optimum working temperature scope of battery, to improving battery performance, extending battery life is most important.
The utility model content
Shortcoming and deficiency that the utility model exists in order to overcome prior art, provide a kind of battery of electric vehicle air-cooling apparatus.
When structure of the present utility model can guarantee that cooling-air is flowed through in battery case each battery module, flow velocity is even, thereby makes the heat radiation of each battery module even.
The utility model adopts following technical scheme:
A kind of battery of electric vehicle air-cooling apparatus, comprise battery case, and described battery case inside arranges a plurality of interconnective battery modules, also comprises a plurality of disturbing flow devices, and described a plurality of disturbing flow devices are arranged on the inwall of battery case both sides along the flow of cooling air direction.
The cross section of described disturbing flow device be half round post, waveform, zigzag or square in a kind of.
The height of described disturbing flow device is identical with the height of battery module, and the arrangement mode of described disturbing flow device and adjacent battery modules and the arrangement mode of battery module are consistent.
Distance between adjacent disturbing flow device equates with the distance between adjacent battery modules.
The arrangement mode of described battery module is along row or stagger arrangement.
With respect to prior art, the utlity model has following advantage:
Flow direction along cooling-air, after on the inwall of battery case both sides, disturbing flow device being set, when cooling-air is flowed through interior each battery module of battery case, nowed forming everywhere is identical with flow velocity, thereby can guarantee the uniformity of temperature profile of each battery module in battery case.

Shown in figure:
The 101-battery case, 102-battery module, 103-disturbing flow device, 104-battery case inwall.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited to this.
Embodiment
As shown in Figure 1, a kind of battery of electric vehicle air-cooling apparatus, comprise battery case 101, described battery case inside arranges a plurality of interconnective battery modules 102 and a plurality of disturbing flow device 103, and described a plurality of disturbing flow devices 103 are arranged on battery case 101 both sides inwalls along the flow of cooling air direction.The cross section of described disturbing flow device 103 be half round post, waveform, zigzag or square in a kind of, the flow direction of described cooling-air is the direction of arrow in accompanying drawing 1.
The height of described disturbing flow device 103 is identical with the height of battery module 102, the arrangement mode of described disturbing flow device 103 and adjacent battery modules and the arrangement mode of battery module 102 are consistent, distance between adjacent disturbing flow device 103 equates with the distance between adjacent battery modules 102, and described battery module is for along being listed as or being staggered in arrangement.
Embodiment 1
As shown in Figure 2, 10 columniform battery modules 102 are set in the battery case 101 of the present embodiment, described battery module 102 is staggered in arrangement, the flow direction of described cooling-air is the direction of arrow in accompanying drawing 2, flow direction along battery case 101 internal cooling airs, on battery case 101 both sides inwalls, disturbing flow device 103 respectively is set, described disturbing flow device 103 is half-cylindrical, the height of disturbing flow device 103 equates with the height of battery module 102, distance between adjacent disturbing flow device 103 on described battery case 101 both sides inwalls equates with the distance between adjacent battery modules 102, described battery module is for being staggered in arrangement, therefore disturbing flow device 103 is staggered in arrangement with adjacent battery module 102, disturbing flow device 103 manufactures an integral body with battery case inwall 104, with same material, manufacture.
Embodiment 2
As shown in Figure 3, the present embodiment difference from Example 1 is, described battery module 102 is rectangular structure, and the cross section of described disturbing flow device 103 is rectangle, and its size is half of battery module 102.
Embodiment 3
As shown in Figure 4, the battery module 102 of the present embodiment is 8, adopt in-line arrangement in battery case 101, along being provided with semi-cylindrical disturbing flow device 103 on the both sides inwall of flow of cooling air direction battery case 101, described disturbing flow device 103 and the same in-line arrangement that adopts of adjacent battery modules 102, other features are identical with embodiment 1.
Described disturbing flow device 103 can be processed into an integral body with battery case inwall 104, also can design separately, then is nested on battery case inwall 104.
Adopt a plurality of battery modules 102 of the interior general placement of air cooled battery case 101, these battery modules 102 can also can be staggered in arrangement along row, during battery module 102 in cooling-air is flowed through battery case 101, because battery module 102 is different with space and shape between shape and battery module 102 from the space between battery case inwall 104, thereby make cooling-air flow through near the flow regime of the battery module 102 of battery case inwall 104 and flow through flow regime difference between battery module 102, make like this cooling effect difference of each battery module 102, thereby cause the temperature distributing disproportionation between battery module 102 even.Flow direction along battery case 101 internal cooling airs, on the inwall of battery case both sides, disturbing flow device 103 respectively is set, can make cooling-air flow through the flow velocity of each battery module 102 in battery case 101 even, the heat radiation of each battery module 102 is consistent, thereby makes the uniformity of temperature profile of each battery module 102 in battery case 101.
Above-described embodiment is preferably execution mode of the utility model; but execution mode of the present utility model is not limited by the examples; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection range of the present utility model.
