Description
Technical field
The utility model belongs to field of batteries, particularly a kind of battery pack guiding structure.
Background technology
Along with resources such as primary energy such as oil, natural gas become more and more in short supply, the mankind are faced with the severe challenge that living environment may constantly worsen.For reducing energy cost and realizing the sustainable development in the world, the research of energy storage technology has all been carried out in countries in the world, and its thinking is exactly to adopt the battery of big merit capacity as energy storage system.Therefore select suitable battery to also become one of key of development energy storage technology.
Owing in energy-storage system, need the battery pack of high voltage high power capacity, therefore need at first battery to be carried out connection in series-parallel, could use then.Battery all is to produce heat in charge and discharge process, after the battery strings parallel connection, because the gap is little between the battery, the casing ventilation quantity is not enough, causes the bigger temperature contrast of appearance between the monomer.This solves this problem with regard to a kind of suitable battery pack guiding structure of needs, existing battery and the battery temperature influence is bigger, when the serviceability temperature of battery not simultaneously, will cause inconsistent in the FCL battery, thereby the useful life of the whole Battery pack of influence, and stay potential safety hazard.Existing battery pack guiding structure is installed a flat board at an end of battery pack inlet side usually, this flat board and battery pack inlet side are in a certain angle, though the flow guiding structure of this structure can keep entering the intake velocity unanimity in gap between the battery, but the wind speed that enters the battery gap is constant all the time, when using as the very big battery of this heat dissipation capacity of lithium ion battery, the radiating effect of this flow guiding structure is still undesirable, is difficult to guarantee that the cooling effect to battery reaches best.
The utility model content
For overcoming the above-mentioned defective of prior art, the purpose of this utility model is to provide a kind of not only can make the gap air intake between the battery even, also has the battery pack guiding structure that can accelerate wind speed, strengthen cooling effect.
The utility model is achieved through the following technical solutions:
A kind of battery pack guiding structure, this flow guiding structure is installed in the inlet side of battery pack, battery pack is fixed by clamping plate that are arranged on its both sides and the angle steel II that is connected between clamping plate, it is characterized in that: this flow guiding structure comprises that cross section is the drainage plate of V-arrangement, all leaves the slit between described each drainage plate.
Wherein, the upper/lower terminal of described each drainage plate all is connected on the block plate, and the outside of described two block plates respectively is welded with an angle steel I.
Wherein, described drainage plate is by two affixed forming of hardboard, and the angle between two hardboards of described drainage plate is 30 °-150
Wherein, the height of two of described drainage plate hardboards is equal to or greater than the height of battery pack.
Wherein, the width of described two hardboards is not less than 20mm.
Wherein, the width of described two hardboards is 20-100mm.
Wherein, described two hardboards are plastic plate or steel plate.
The beneficial effects of the utility model are: battery pack guiding structure of the present utility model not only can make the gap air intake between the battery even, consistent, also play the effect of accelerating wind speed, strengthening cooling effect, so, fail safe when increase flow guiding structure of the present utility model can effectively guarantee the battery pack use on the inlet side of battery pack, and can prolong the useful life of battery pack.

Embodiment
Below in conjunction with accompanying drawing the battery pack guiding structure in the utility model is further described in detail.
As shown in Figure 1-Figure 3, the a plurality of drainage plates 1 of this flow guiding structure of flow guiding structure of the present utility model are formed, the cross section that this drainage plate is seen from top to bottom is a V-arrangement, all leave the slit 2 that the gap with battery adapts between each drainage plate, be connected with a steel plate 5 respectively in the top and bottom of all drainage plates, respectively weld an angle steel I 3 in the outside of two steel plates 5, all drainage plates link together by two steel plates 5, and the drainage plate that will be welded with behind the steel plate 5 by two angle steel I is connected in the battery case again.Each drainage plate 1 is welded by two hardboards (can adopt materials such as plastic plate or steel plate).For guaranteeing that cooling effect reaches best, angle between should two hardboards of drainage plate 1 is set to 30 °-150 °, should make the height of two hardboards of drainage plate 1 be equal to or greater than the height of battery pack 4, the width of two hardboards of drainage plate 1 should be for good less than 20mm, with the width between the 20mm-100mm.
As shown in Figure 4, this flow guiding structure is installed on air intake one side of battery pack 4, battery pack 4 is made up of 8 batteries, and battery pack is fixed by clamping plate 41 that are arranged on its both sides and the angle steel II 42 that is connected between clamping plate, and the installing hole bottom clamping plate is fixed on battery pack in the battery case 43.Owing to have 7 gaps between 8 batteries, and also be provided with the gap between outermost two batteries and the clamping plate 41, so have 9 gaps, this routine flow guiding structure is made up of 10 drainage plates 1, the upper/lower terminal of 10 drainage plates 1 is welded on respectively on the block plate 5, be reserved with 9 slits 2 between each drainage plate 1 of fixing by steel plate 5, between these 9 slits 2 and the battery and 9 gaps between battery and the clamping plate are corresponding one by one, and then by two angle steel I 3 that are welded on the steel plate 5 this flow guiding structure are fixed in the battery case 43.Because the cross section V-shaped (as shown in Figure 3) of drainage plate 1 makes that the opening between each drainage plate also presents V-arrangement, when cold wind passed through this drainage plate, the wind speed that enters in the battery gap was obviously accelerated, and can take away the heat in the battery gap fast.For can reach accelerate wind speed again can conservation and battery case in the purpose in space, can the dismantle hardboard in the outside of two of outermost in 10 drainage plates 1, the drainage plate that is adjacent with a hardboard constitutes slit 2, and these two slits 2 are corresponding with the gap that battery and clamping plate are constituted.
The setting of this V-arrangement drainage plate not only can make the gap air intake between the battery even, consistent, also play the effect of accelerating wind speed, strengthening cooling effect, so, fail safe when increase flow guiding structure of the present utility model can effectively guarantee the battery pack use on the inlet side of battery pack, and can prolong the useful life of battery pack.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to the foregoing description, those of ordinary skill in the field are to be understood that: still can make amendment or be equal to replacement embodiment of the present utility model, and do not break away from any modification of the utility model spirit and scope or be equal to replacement, it all should be encompassed in the middle of the claim scope of the present utility model.
