Description
Technical field:
The present invention relates to a kind of cylindrical battery group, it belongs to field of batteries.
Background technology:
Existing cylindrical battery group is by using after the connection in series-parallel in groups of multiple batteries the most mostly, in each electric automobile and storage
Needing the set of cells of high voltage high power capacity in energy system, battery is arranged more than the big quantity of volume in groups, in addition between both positive and negative polarity
Connection in series-parallel relation, battery intermediate space is the least.The forms such as general employing is air-cooled in battery dispels the heat, natural cooling,
Owing to battery is in charge and discharge process, internal chemical reaction complexity, and it is attended by the generation of heat, especially for multiple
The device of battery cell composition, the heat history in the middle of arrangement easily formation that the least gap is closeer, the gathering of temperature
Faster, inside battery is made to produce rapidly substantial amounts of heat build-up, it is necessary to cause battery temperature rising and Temperature Distribution not
Equilibrium, thus causes battery performance to decline, it is possible that leakage, exit, the phenomenon such as smolder, time serious, battery can be sent out
Even there is the danger of blast in raw vigorous combustion.
Moreover, battery owing to being limited by module module assembling itself, causes cylindrical battery to exist after connection in series-parallel in groups
Also occupies battery major part area itself in connected mode, the cell gap being so equivalent to itself reserved is few,
Bottom or intermediate cell cannot obtain effective heat dissipation environment, also cannot effectively take away the heat of battery itself after installing fan additional
Amount, when battery temperature in use is different, will result in FCL battery is inconsistent, thus affects making of whole Battery pack
With the life-span, and leave potential safety hazard.
Summary of the invention:
For defect of the prior art, the present invention provides a kind of cylindrical battery group, and it has good heat transfer heat dissipation channel.
The present invention adopts the following technical scheme that a kind of cylindrical battery group, including fin, aluminium base, heat pipe, cylinder electricity
Pond and cooling stand, the outer layer of described cylindrical battery is wrapped up by dielectric film, and two ends are respectively anode ear and negative electrode lug,
On the outer surface of described cooling stand uniform intervals depression be formed several for the groove placing cylindrical battery, described
The centre position of cooling stand offers through hole, and the bearing of trend of described through hole is consistent with the bearing of trend of cylindrical battery,
Described heat pipe includes connecting portion and terminal part, and terminal part is installed in through hole, and connecting portion is installed on the side table of aluminium base
On face, on the opposite side surface of aluminium base, laminating assembles fin.
Further, described cooling stand is made up of commercial-purity aluminium.
Further, the spacing between adjacent two cylindrical battery being installed on groove is 1.5-3 millimeter, through hole
A diameter of 3.5-10 millimeter.
Further, described heat pipe be shaped as U-shaped, linear, S-shaped or M shape.
Further, described heat pipe is pipe, flat tube or rectangular tube.
There is advantages that cylindrical battery in charge and discharge process, internal chemical reaction complexity, and adjoint
Having the generation of heat, the cylindrical battery group formed especially for multiple cylindrical batteries, the gathering of temperature faster, makes cylinder
Internal battery pack produces rapidly substantial amounts of heat build-up, it is necessary to cause the rising of cylindrical battery group temperature and Temperature Distribution not
Equilibrium, cylindrical battery group of the present invention fits tightly cylindrical battery surface by heat absorption by cooling stand, then passes through heat
Pipe conducts heat on aluminium base, then carries out heat absorption diffusion by the fin on aluminium base.

Detailed description of the invention:
Refer to shown in Fig. 1 to Fig. 8, cylindrical battery group of the present invention includes fin 1, aluminium base 2, heat pipe 3, cylinder
Battery 4 and cooling stand 5.The profile of cylindrical battery 4 is cylindrical, and outer layer is wrapped up by dielectric film, and two ends are respectively
For anode ear and negative electrode lug.Cooling stand 5 is made up of commercial-purity aluminium, and existing good thermal conduction characteristic has again certain hard
Degree.On the outer surface of cooling stand 5 uniform intervals depression be formed several for the groove 50 placing cylindrical battery 4,
The effect one of groove 50 is to play positioning cylinder battery 4, and two is that the heating face of cylindrical battery 4 fits tightly with groove 50,
Be conducive to the heat radiation of cylindrical battery 4.As a further improvement on the present invention, when battery is at high rate charge-discharge, and heat is relatively
Time big, the dielectric film of cylindrical battery outer layer can be peeled off, the groove surfaces of cooling stand be carried out insulation processing simultaneously.
The bearing of trend of through hole 51, the bearing of trend of through hole 51 and cylindrical battery 4 is offered in the centre position of cooling stand 5
Consistent.Spacing between adjacent two cylindrical battery 4 being installed on groove 50 is 1.5-3 millimeter, through hole 51
