Description
Technical field
The invention relates to a kind of heat dissipation battery module, be especially suitable for the heat dissipation battery module applied on the electronic device.
Background technology
Be that people bring many convenient parts because of electronic product in life, the particularly Related product such as portable electronic product or motor vehicle, in order to enable these electronics or electric product normal operation, the existence of battery just seems quite important.Moreover along with user elongates for the Time-Dependent of electronic product, the relative battery spendable electric power life-span also needs to increase, and adapts to such demand, and have the feature of environmental protection concurrently again, high efficiency rechargeable battery can meet demand simultaneously.
Inevasible, high efficiency rechargeable battery is in the process of charge or discharge, the battery material (as lithium electronics) of its inside can produce a large amount of heats when carrying out ion-exchange, inner working temperature is caused to increase, and then generation thermal resistance effect, and then drag down the work effect electricity of its charge or discharge, therefore, for making its working temperature keep stable, the heat radiation countermeasure of battery becomes an important key of battery effect electricity undoubtedly.But, current battery structure, be provided with the battery that is arranged in body interior, the heat that this battery produces directly conducts on body, heat exchange action is carried out to dispel the heat again by body and outside air, but the fit of battery and body is loose supporting conjunction, although be free air-flow to move during use carry out heat exchange with the exterior surface of body, but the limited area of battery and body contacts, therefore cause the efficiency of heat exchange action not enough, cause the accumulation of heat of follow-up generation inner in battery body, inner working temperature and thermal resistance is caused constantly to rise, have a strong impact on its charge or discharge usefulness, very undesirable.
Summary of the invention
An object of the present invention, is to provide a kind of heat dissipation battery module with better radiating effect.
In order to reach above-mentioned object, the present invention comprises a metal shell, at least one battery and elastomer, metal shell is arranged with an accommodation space, the side of accommodation space is an opening, opening is configured with top cover, top cover has plural profile groove, battery is placed in accommodation space, the top of this battery is provided with positive and negative electrode polarity tab, positive and negative electrode polarity tab is worn and is exposed outside profile groove, elastomer is inserted in a side of battery, elastomer contact battery, makes battery large area abut against in metal shell.
Another object of the present invention, is providing a kind of heat dissipation battery module increased and decreased with electricity user demand.
The present invention compared to the advantage that prior art is outstanding is:
1, utilize thermal conductivity preferably metal shell carry out set battery core, effectively improve conventional plastic shell and do not have a shortcoming of thermal conductivity.
2, elastomericly to install by one, order is placed in the battery of metal shell can bump contact metal shell, and the heat energy that battery start is given birth to, is able to be passed to metal shell sooner by bump contact.
3, elastomer not only provides the power supported, and makes battery and metal shell bump contact, contains heat-conducting medium simultaneously, more can outwards be conducted by the heat of battery further in elastomer.

Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described, can better understand the present invention and can be implemented, but illustrated embodiment is not as a limitation of the invention to make those skilled in the art.
Please refer to the drawing 1, Fig. 2, be respectively the three-dimensional element exploded view of the embodiment of the present invention and the stereo appearance figure of the embodiment of the present invention; Heat dissipation battery module 1 of the present invention comprises a metal shell 11, at least one battery 19 and an elastomer 18.
This metal shell 11 is aluminum or aluminum alloy material, it is arranged with an accommodation space, the side of this accommodation space is an opening 12, this opening 12 is configured with a top cover 14, and this top cover 14 has plural profile groove, in addition, this metal shell 11 periphery has plural combined hole, the relative dual side-edge of metal shell 11 has plurality of radiating fins 13, and top cover 14 is provided with three pole pieces 15,16,16 ', and this little pole piece 15,16,16 ' is provided with plural profile groove.
The top of battery 19 is provided with positive and negative electrode polarity tab 20,20 ', and battery 19 is placed in the accommodation space of metal shell 11, and this positive and negative electrode polarity tab 20,20 ' is worn and exposed outside those profile grooves; The present embodiment is provided with four battery 19, the position of the position of the profile groove on this top cover 14 and the polarity tab 20,20 ' of quantity matching battery core 19 and quantity and establish.
Elastomer 18 is inserted in battery 19 side, and this this battery 19 of elastomer 18 contact, abuts against in metal shell 11 to make battery 19 large area; The elastomer 18 of the present embodiment is placed between two between battery 19, and this elastomer 18 is made for the elastic material such as silica gel, rubber.
Please refer to Fig. 3, Fig. 4, be the vertical section schematic diagram of the embodiment of the present invention and the schematic cross section of the embodiment of the present invention; Elastomer 18 is folded in after between two between battery 19, insert in the lump again in the accommodation space of metal shell 11, and top cover 14 is covered on the opening 12 of metal shell 11, and make the polarity tab 20,20 ' at four battery 19 tops respectively through the profile groove of top cover 14 3 pole piece 15,16,16 ', polarity tab 20,20 ' and three pole piece 15,16,16 ' of four battery 19 is contacted with each other and outside being revealed in, and the root edge of top cover 14 is provided with the zigzag protuberance 17 for compressing battery 19.
Moreover the battery 19 of elastomer 18 2 side is subject to shoring and outwards pushing of elastomer 18, making the battery 19 outside two each is that large-area subsides are touched with metal shell 11, therefore the heat conduction that can the battery 19 outside two be given birth to rapidly is to metal shell 11.In addition, this elastomer 18 also can include heat-conducting medium, and the heat conduction of battery 19 being given birth to rapidly according to this to metal shell 11, and passes through radiating fin 13 set on it, to be left by heat fast.Elastomer also can be silica gel or quality of rubber materials.
The above embodiment is only that protection scope of the present invention is not limited thereto in order to absolutely prove the preferred embodiment that the present invention lifts.The equivalent alternative or conversion that those skilled in the art do on basis of the present invention, all within protection scope of the present invention.Protection scope of the present invention is as the criterion with claims.
