Description
Technical field
The utility model relates to energy field, particularly relates to a kind of overcurrent radiator of soft-package battery.
Background technology
Increasingly serious along with the energy and environmental problem, electric automobile progressively substitutes traditional power automobile, and electric automobile has become a large branch of automobile industry at present.Lithium-ion-power cell, because of the advantage such as high rate performance, long-life, safety of its excellence, has become the first battery of current electric automobile, has obtained the accreditation of whole industry.
Electrokinetic cell plays the part of a stored energy person on electric automobile, is stored in battery by unnecessary energy the etc. when energy in electrical network, vehicle brake, is released by the energy in battery in motion, the needs run to provide car load.In the use of lithium-ion-power cell, the temperature difference of important is battery with two side terminals, environment for use, connect internal resistance difference etc., and wherein, the temperature difference opposite sex having the greatest impact to lithium-ion-power cell, in general, the best serviceability temperature of lithium-ion-power cell between 20 DEG C ~ 45 DEG C, but due to the running environment more complicated of car load, low temperature may to subzero 20 DEG C, and high temperature may to 55 DEG C.So be badly in need of a kind of radiating mode for battery pack stable reliably.
The power of motor that current electric automobile is selected is all comparatively large, and the discharge-rate of battery is higher, so require all higher to the conveyance capacity of the series and parallel busbar of internal battery pack.Moreover nonferrous metal price is tending towards the trend gone up, and the price of the copper particularly used as conductor, price goes up especially, makes the production cost of battery pack more and more higher every year year after year.
Utility model content
The purpose of this utility model is the defect overcoming prior art, provides a kind of overcurrent radiator of soft-package battery, and its structure is simple, and be convenient to manufacture, cheap for manufacturing cost, perfect heat-dissipating, conveyance capacity is strong.
The utility model is achieved in that a kind of overcurrent radiator of soft-package battery, and it comprises:
Pedestal, parallel and be provided with and arrange radiating fin, gap-forming welding groove between described radiating fin more between waiting on described pedestal, described pedestal is connected with described radiating fin is one-body molded.
Further, the outer surface of described radiating fin is set to zigzag.
Further, described radiating fin comprises root and tip, and the thickness of described tip reduces along the root of radiating fin gradually to top-direction.
Further, the material of described pedestal and radiating fin is set to aluminium alloy.
Further, described pedestal also has flat part, described flat part is arranged between two row's radiating fins.
Further, described flat part has multiple draw-in groove.
The beneficial effect that the utility model provides is: structure is simple, and be convenient to manufacture, cheap for manufacturing cost, perfect heat-dissipating, conveyance capacity is strong.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the stereogram of the overcurrent radiator of a kind of soft-package battery of the utility model embodiment;
Fig. 2 is the end view of the overcurrent radiator of a kind of soft-package battery of the utility model embodiment;
Fig. 3 is the partial enlarged drawing of A in Fig. 2.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the overcurrent radiator of a kind of soft-package battery of the utility model embodiment comprises:
Pedestal 10, parallel and be provided with many row's radiating fins 11 between waiting on described pedestal 10, gap-forming welding groove 12 between described radiating fin 11, described pedestal 10 is connected with described radiating fin 11 is one-body molded.
It should be understood that, the negative pole end of soft-package battery is the first heat generating spot of battery core, positive terminal is the second heat generating spot of battery core, therefore lug position is the main heating end of soft-package battery, and owing to connecting the impact of internal resistance, lug position is made to be the maximum temperature point of battery core, on the other hand because lug is connected with battery core by multilayer pole piece, therefore for making battery lower the temperature, lug position should be the best heat radiation point of battery core, so carry out concentrating heat radiation to the lug position of battery core, best effect will be had.
During use, the plus or minus pole lug of soft-package battery is inserted the welding groove 12 between radiating fin 11, by the mode welded or crimp, cell polar ear is connected with radiating fin 11, radiator 1 is soft-package battery heat radiation by pedestal 10 and radiating fin 11, radiator 1 also can as the series connection busbar of battery pack or parallel busbar simultaneously, increase ampacity, the utility model overcurrent radiator 1 structure is simple, be convenient to processing and manufacturing, overcurrent busbar can be done while heat radiation, both the conveyance capacity that radiating requirements too increases electric current had been met, there is splendid economy, reduce the manufacturing cost of battery.
Further, as shown in Figure 3, the outer surface of described radiating fin 11 is set to zigzag, and jagged outer surface increases area of dissipation, considerably increases heat exchanger effectiveness, when the little amplitude of volume increases, significantly can increase heat-sinking capability.
Further, as shown in Figure 2 and Figure 3, described radiating fin 11 comprises root 111 and tip 112, the thickness of described tip 112 reduces along the root 111 of radiating fin 11 gradually to top-direction, add surface area on the one hand, increase heat-sinking capability, on the other hand the shape of welding groove 12 is more mated with the lug partial shape of soft-package battery.
Further, the material of described pedestal 10 and radiating fin 11 is set to aluminium alloy.
Further, described pedestal 10 also has flat part 13, described flat part 13 is arranged between two row's radiating fins 11.
Further, described flat part 13 has multiple draw-in groove 131, and sampling wire harness is installed within draw-in groove 131, can be fixed on pedestal 10 by being welded and fixed, crimping fixing, that bolt is fixing mode.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
