Abstract
The utility model discloses a nickel metal hydride power battery heat dissipation outer shell and belongs to the technical field of a power battery. The nickel metal hydride power battery heat dissipation outer shell comprises an outer shell, a positive electrode post and a negative electrode post, wherein the positive electrode post and the negative electrode post are arranged at the top of the aluminum alloy outer shell. The nickel metal hydride power battery heat dissipation outer shell is characterized in that a plurality of reinforcing ribs are arranged on the outer portion of the outer shell (3) so that the outer shell in a heat radiator shape is formed. Heat of the battery is transmitted to the outer shell and due to the fact that the heat dissipation function of the shell is enhanced, the heat is transmitted outside. Meanwhile, insulation level of the battery shell is improved, self discharge of the battery is reduced, insulation of the battery is increased, compression resistance of the shell is increased and the shell is prevented from deformation. Due to the facts that an inner lining is made of insulating plastic and a positive electrode and a negative electrode of a pole shank of the battery are insulated from the outer shell through a sealing ring, a safety coefficient in use of the batteries in a bunching mode is improved, an insulation plate between single batteries is removed and heat dissipation is facilitated. Meanwhile, the self discharge of battery polarity relative to the outer shell is reduced correspondingly.
Description
Technical field
The Ni-MH power cell heat-dissipating casing, belong to the power battery technology field.
Background technology
Ni-MH power cell is with characteristics such as its high security, long-life, wide warm area, permission high current charge-discharges, more and more wider by electric automobile, back-up source, stored energy field and other field range of application gradually.But large capacity Ni-MH power cell is accompanied by a large amount of heat generations in the large current density electric process, this part heat is as be delivered to not in time outside shell and dissipated and will affect use and the life-span of battery.The employing plastic casing that existing power capacitor batteries has, also have the employing stainless steel casing, and radiating effect is all undesirable.And adopt the battery of stainless steel casing, connect between its both positive and negative polarity and shell and still have certain connection resistance by electrolyte, thereby aggravate its self discharge.In addition due to battery charging process with outgas reaction, the cell internal pressure increase causes the battery case distortion.
Summary of the invention
Problem to be solved in the utility model is: overcome the deficiency that prior art exists, provide a kind of and can make the indeformable Ni-MH power cell heat-dissipating casing of quick heat radiating, the shell of Ni-MH power cell in charge and discharge process.
The utility model solves the technical scheme that its technical problem adopts: this Ni-MH power cell heat-dissipating casing, comprise shell, outer casing bottom is that battery base plate, top are the battery top board, battery base plate and battery top board all are connected and fixed and become one by bolt and shell, positive and negative terminals is drawn from cover top portion, it is characterized in that: described housing exterior arranges the shell that many reinforcements form the radiator shape;
Described shell inboard arranges liner, and border, liner bottom seals by sealing ring, and the positive and negative terminals border is connected with body seal by sealing ring.
Preferably, described shell adopts plastic material by injection mo(u)lding.
Described liner is that ambroin is made.
Compared with prior art, the useful effect that the utility model Ni-MH power cell heat-dissipating casing has is: the battery heat can be delivered to shell, again by strengthening the heat sinking function of housing, heat is delivered to the external world fast, take into account the insulation level that promotes battery container simultaneously, reduce the self discharge of battery, increase the insulation of battery, increase the housing resistance to compression and prevent the advantages such as housing distortion.Because liner is ambroin, Battery Pole Core both positive and negative polarity and shell insulate by sealing ring, have improved coefficient of safety when battery is applied in groups.The insulating barrier omitted between battery cell is more conducive to heat radiation.Simultaneously correspondingly reduced the self discharge of battery polar with respect to shell.
The accompanying drawing explanation
Fig. 1 is the main TV structure cross-sectional schematic of utility model.
Fig. 2 is the end view of utility model.
Wherein: 1, pole 2, liner 3, shell 4, battery base plate 5, battery top board.
Embodiment
Fig. 1-2 is most preferred embodiment of the present utility model.Below in conjunction with accompanying drawing, Ni-MH power cell heat-dissipating casing of the present utility model is described further.
With reference to Fig. 1-2
:This Ni-MH power cell heat-dissipating casing, be comprised of positive and negative terminals 1, liner 2, shell 3, battery base plate 4 and battery top board 5.Many reinforcements of described shell 3 outer setting form the shell of radiator shape, shell 3 inboards arrange liner 2, shell 3 bottoms are that battery base plate 4, top are battery top board 5, battery base plate 4 and battery top board 5 all are connected and fixed and become one by bolt and shell 3, positive and negative terminals 1 is from shell 3 Base top contacts, and described shell 3 adopts plastic material by injection mo(u)lding.Described liner 2 is made for ambroin.Liner 2 borders, bottom seal by sealing ring, and positive and negative terminals 1 border is connected with body seal by sealing ring.
Operation principle and the course of work: during use, the positive/negative plate of Ni-MH power cell is installed in the enclosure, the battery top board 5 on positive plate and top is connected and fixed as the positive collector plate in top, and the battery base plate 4 of negative plate and bottom is connected and fixed as the negative collector plate in bottom.By positive and negative terminals 1, with both positive and negative polarity stream plate, by sealing ring, seal fixing respectively.When Ni-MH power cell is charged, the shell 3 of described radiator shape, because the heat that increase housing area of dissipation can transmit out by inside battery falls apart to space, is suitable for air-cooled or water-cooled simultaneously.So Insulation Problems in the time of solving water-cooled with shell by insulated liner 2 insulation because Ni-MH power cell is inner.Because shell 3 has been made the radiator shape.Be equal to and increased many reinforcements on shell 3, the compression strength that has increased shell 3 has also played the effect that prevents shell 3 distortion.
Described shell 3 adopts injection mo(u)lding.Both can meet the insulation standard and guarantee Ni-MH power cell and shell 3 insulation.Reduced Ni-MH power cell needs to increase the insulating radiation dividing plate simultaneously when using in groups between monomer, simplified assembling mode, is more conducive to heat radiation.
The above, it is only preferred embodiment of the present utility model, be not the utility model to be done to the restriction of other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection range of technical solutions of the utility model.
