Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
See Fig. 1-2, the invention provides a kind of heat exchange structure of power battery system, comprising: electrokinetic cell 1, electrokinetic cell 1 connects the intake stack 2 extend in compartment, and intake stack 2 is to electrokinetic cell conveying carriage inner air.This air themperature is synchronous with air conditioner in compartment, not affected by ambient temperature, and the hearsay of this interior is defeated by electrokinetic cell 1, makes electrokinetic cell can obtain good heat exchange effect.
In order to more obtain interior air, this electrokinetic cell 1 has air blast (not shown), and this air blast connects intake stack 2, with negative pressure mode extracting air.Air-dryly defecate clean in order to what make to enter intake stack, screen pack 3 is installed in the end led in compartment at intake stack 2.
In order to make electrokinetic cell inside complete First air circulation, in this electrokinetic cell 1, being provided with the wind pipe 4 of air-out to be discharged outside car body, accelerating the circulation of electrokinetic cell inner air, reaching the effect of fast cooling or insulation.
In order to prevent the dust in compartment, silt, rinse water or foreign material from entering blocking screen pack, exterior end cover air intake cover of present intake stack 2, this air intake cover adopts thickness δ=1.5mm steel plate punched shaping.
This air intake cover comprises cover body 5, the sidewall of this cover body 5 has multiple fresh air inlet 51.In order to prevent dust, silt, rinse water or the foreign material blocking fresh air inlet 51 in compartment further; the edge 6 of multiple externally below extension is set at the outer surface of sidewall; this edge is positioned at the top of fresh air inlet; under the protection at edge 6; dust in this compartment, silt, rinse water or foreign material enter into air intake cover by being difficult to; and then farthest guarantee the air-dry clean cleaning that enters in intake stack 2, be convenient to cooling or the insulation of electrokinetic cell 1.
In addition, the bottom of air intake cover is provided with sealing gasket 8, is sealed into fan housing further.This intake stack 2 passes sealing gasket 8 and is arranged in air intake cover cover body 5.
According to actual installation situation, this electrokinetic cell is usually located in the battery settling groove of bottom, floor, learn after analyzing existing body construction, connect extend into intake stack in compartment preferably connected mode by intake stack through the floor 9 in compartment, and then extract the air in compartment.Air intake cover is fixedly connected on floor 9 on the surface, is specially, and the bottom surrounding of air intake cover has outward extending flanging 7, described flanging has installing hole 71, flanging 7 can be fixed on floor 9 on the surface by bolt.
It should be noted that, the mode that this intake stack 2 obtains air in a car compartment is not limited to through floor surface, along with the change of carriage body construction, other modes also can be adopted to realize obtaining interior air.
In addition, the heat exchange structure of power battery system that the embodiment of the present invention provides, when outdoor temperature colder even lower than subzero time, now interior air themperature will higher than outdoor temperature, and now this intake stack can make the temperature of electrokinetic cell remain on one preferably in working range to the warmer wind that electrokinetic cell provides, avoid the destruction of extraneous cold gas to electrokinetic cell service behaviour, and then electrokinetic cell can be made to reach a preferably service behaviour state, improve the security performance of car load.
In battery system heat exchange structure provided by the invention, the air in a car compartment playing radiating effect enters into air intake cover under the negative pressure extracting of air blast, electrokinetic cell internal pipeline is entered into by intake stack 2, by under inner fan effect, the wind completing heat exchange is blown out by wind pipe 4.
Heat exchange structure of power battery system provided by the invention, structure is simple, air inlet not easily blocks, by adopting the air gathering interior, the cooling process of hot weather and the isothermal holding of cold snap are carried out to electrokinetic cell, ensure that the stable performance of electrokinetic cell performance, and then improve safety and the serviceability of car load.
Above execution mode is only for illustration of the present invention; and be not limitation of the present invention; the those of ordinary skill of relevant technical field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all equivalent technical schemes also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
