Description
Technical field
This utility model relates to technical field of lithium batteries, particularly relates to a kind of quick heat radiating lithium battery.
Background technology
Lithium battery, because of its technology maturation, use safety and stability, is widely used in the power supply of electronic product.Existing lithium battery is mostly square configuration, when large current density, battery surface temperature is high, easily to the electronic devices and components of adjacent cells groove, lithium battery whole face, temperature conduction is affixed on lithium battery groove, not easy heat radiation, can affect battery itself and the use of ambient electron components and parts.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of quick heat radiating lithium battery.
The technical solution of the utility model is as follows:
A kind of quick heat radiating lithium battery, square shell, upper cover body, middle lid and lower cover including one end open, described square shell is provided with upper chamber, middle chamber, lower chambers, middle chamber built-in lithium battery battery core, and closed by middle lid, upper and lower chamber housing refrigerant, and point sealed by upper and lower cover body；The closely middle lid one end of lithium battery electric core is provided with anode ear and negative electrode lug；The external side of described middle cover is provided with cathode output end and cathode output end, and described anode ear is connected with cathode output end, and negative electrode lug is connected with cathode output end；It is additionally provided with charging aperture to be opened/closed on described upper and lower lid.
Between described upper chamber and upper cover body, between lower chambers and lower cover, it is equipped with seal washer.
Described seal washer is made up of soft plastic.
Using such scheme, this utility model upper and lower cavity indoor envelope has refrigerant, and easily absorb heat material such as solid ice, liquid water etc., sets lithium battery electric core in middle chamber.Lithium battery after encapsulation is when discharge and recharge, the refrigerant that the heat major part that lithium battery produces is distributed up and down absorbs simultaneously, be conducive to heat dissipation of lithium battery, by refrigerant, the heat of absorption is dissipated through square shell conduction again after battery temperature reduces, be conducive to the dissipation of the heat of lithium battery own, overheated for preventing, the refrigerant of heat absorption can be replaced from the charging aperture of upper and lower lid, thus be unlikely to lithium battery itself and ambient electron components and parts thereof are had a negative impact.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is explosive view of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
Referring to figs. 1 through shown in Fig. 2, this utility model provides a kind of quick heat radiating lithium battery, square shell 1, upper cover body 22, middle lid 21 and lower cover 23 including one end open, described square shell 1 is provided with upper chamber 12, middle chamber 11, lower chambers 13, middle chamber 11 built-in lithium battery battery core 3, and closed by middle lid 21, upper and lower chamber 12,13 accommodates refrigerant, and divides by upper and lower cover body 22,23 sealing；During lithium battery electric core 3 is near, lid 21 one end is provided with anode ear 31 and negative electrode lug 32；Being provided with cathode output end 211 and cathode output end 212 outside described middle lid 21, described anode ear 31 is connected with cathode output end 211, and negative electrode lug 32 is connected with cathode output end 212；Charging aperture 221,231 to be opened/closed it is additionally provided with on described upper and lower lid 22,23.
It is provided with seal washer 41/42 between described upper and lower chamber 12,13 and upper and lower cover body 22,23；Described seal washer 41/42 is made up of soft plastic.
Described seal washer 41/42, up/down lid 22/23 are fixed on up/down chamber 12/13 opening by screw 51/52.
In embodiment shown in Fig. 2, three cavity 12,11, about 13 three-layer arrangement in square shell 1, in upper and lower chamber 12,13, envelope has refrigerant, easily absorb heat material such as solid ice, liquid water etc., and be fixed on upper and lower chamber 12,13 opening part by two ends screw 51/52, seal washer 41,42 be added to strengthen the sealing of upper and lower chamber 22,23；The opening of three chambers of square shell 1 divides and is encapsulated by upper cover body 22, middle lid 21, lower cover 23, is wherein additionally provided with the charging aperture 221,231 that can change refrigerant on lid 22,23 up and down.Lithium battery after encapsulation is when discharge and recharge, the heat major part cooled object produced absorbs, be conducive to heat dissipation of lithium battery, by refrigerant, the heat of absorption is conducted through square shell 1 again after battery temperature reduces and dissipate, overheated for preventing, the refrigerant of heat absorption can be replaced from charging aperture 221,231, beneficially the dissipation of the heat of lithium battery own, thus be unlikely to lithium battery itself and ambient electron components and parts thereof are had a negative impact.
In this utility model, for the replacing of refrigerant, can directly carry out from charging aperture 221,231, Fig. 2 show an example of charging aperture 221,231, depending on its opening size big I state according to actual refrigerant, when solid-state refrigerant changed by needs, its size can be larger；When applying liquid refrigerant, its size can be smaller.
These are only preferred embodiment of the present utility model, be not limited to this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
