Abstract
The utility model provides a lithium ion battery heat dissipating structure, which is applicable to the lithium ion battery field. The lithium ion battery comprises a battery body, a battery housing, a battery protective circuit and a power module. The battery body is equipped inside the battery housing. The battery protective circuit is electrically connected with the battery body. The power module which is electrically connected with the battery protective circuit is equipped on the battery housing. By adopting the above technical scheme, the power module is equipped on the battery housing instead of the battery protective battery. The battery housing can effectively disperse the heat generated by the power module to the outside of the battery and thus a large amount of heat no longer gathers in the power module which is therefore incapable of conducting the heat to the battery protective circuit. Therefore, the power module and the battery protective circuit can keep a normal temperature when in operation and the problems generated by high temperature can be effectively avoided.
Description
Technical field
The utility model belongs to the lithium ion battery field, relates in particular to a kind of radiator structure of lithium ion battery.
Background technology
Existing lithium ion battery generally is equipped with battery protecting circuit and power model, and described battery protecting circuit sends the work of commands for controlling power model, and described power model can effectively be controlled the charging and the outage of battery body; Wherein, described power model comprises metal-oxide-semiconductor, and this metal-oxide-semiconductor can receive the instruction of battery protecting circuit and the charging and the discharge of control lithium ion battery, prevents that battery body is owing to overcharging or over-discharge can causes damage.
The metal-oxide-semiconductor of existing lithium ion battery generally directly is installed on the battery protecting circuit and with battery protecting circuit and is electrically connected.Described metal-oxide-semiconductor can produce a large amount of heats in control lithium ion battery charging and discharging process; because metal-oxide-semiconductor directly is installed on the battery protecting circuit; therefore these heats can not get effectively distributing; be gathered in a large number on the battery protecting circuit, impel the temperature on metal-oxide-semiconductor and the battery protecting circuit significantly to raise.Too high temperature gently then can shorten the useful life of battery protecting circuit and power model on metal-oxide-semiconductor and the battery protecting circuit, and is heavy then can cause burning of battery protecting circuit and scrapping of entire lithium ion battery.
The utility model content
The purpose of this utility model is to provide a kind of radiator structure of lithium ion battery, the problem that the heat that produces when the power model that is intended to solve is worked can not effectively distribute.
The utility model is to realize like this; a kind of radiator structure of lithium ion battery; be used for lithium ion battery; described lithium ion battery comprises battery body, battery case, battery protecting circuit and power model; described battery body is installed in the battery case; described battery protecting circuit is electrically connected with battery body, and described power model is electrically connected with battery protecting circuit, and described power model is installed on the battery case.
Wherein, described power model comprises and is used to control the metal-oxide-semiconductor that battery body discharges and recharges that described metal-oxide-semiconductor is electrically connected with battery protecting circuit.
Wherein, described battery case is cuboid or square, and described metal-oxide-semiconductor is installed on the inner surface of battery case.
Wherein, described battery protecting circuit is arranged on the battery protecting plate, and described battery protecting plate is installed in the battery case.
After adopting above technical scheme, described power model no longer is installed on the battery protection module, but is installed on the battery case.Because described battery case can effectively be dispersed into the heat that power model produces outside the battery; described power model a large amount of heat that do not reassociate; this power model can not conduct heat to battery protecting circuit yet; therefore; described power model and battery protecting circuit all can keep normal temperature when work, effectively avoided the variety of issue that causes owing to temperature is too high.
Description of drawings
Fig. 1 is the battery body that provides of the utility model embodiment and the scheme of installation of battery protecting circuit.
Fig. 2 is the power model that provides of the utility model embodiment and the scheme of installation of battery case.
Fig. 3 is the schematic perspective view of the battery case that provides of the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1-3; the utility model provides a kind of radiator structure of lithium ion battery; the radiator structure of described lithium ion battery is used for lithium ion battery; described lithium ion battery comprises battery body 2, battery case 1, battery protecting circuit 31 and power model 4; described battery body 2 is installed within the battery case 1, and described battery protecting circuit 31 is electrically connected with battery body 2.Wherein, described battery protecting circuit 31 is mainly used in the work of power controlling module 4; Described power model 4 can effectively be controlled the charging and the outage of battery body 2; prevent that battery body 2 is owing to overcharging or over-discharge can is damaged; described battery protecting circuit 31 is arranged on the battery protecting plate 3, and described battery protecting plate 3 is installed within the battery case 1.Because described battery protecting circuit 31 and power model 4 are prior art, therefore its operation principle and the course of work are not elaborated.
See also Fig. 1-3, the shape of described battery case 1 can be according to client's needs customization, in general in the majority with cuboid or square, in the present embodiment, the profile of described battery case 1 is cuboid, and this battery case 1 by thermal diffusivity preferably material make, have heat dispersion preferably.
See also Fig. 1-3, described power model 4 comprises metal-oxide-semiconductor 41, and described metal-oxide-semiconductor 41 is electrically connected with battery protecting circuit, and described metal-oxide-semiconductor 41 is a prior art, and its operation principle and the course of work do not repeat them here.
See also Fig. 2, in the present embodiment, described metal-oxide-semiconductor 41 is installed on the inwall 11 of battery case 1, and itself and battery protecting circuit 31 keep certain interval, very fast the distributing of heat that described battery case 1 produces in the time of metal-oxide-semiconductor 41 can being worked.In addition,, metal-oxide-semiconductor 41 can be installed on a plurality of inwalls on the battery case 1, can obtain better radiating effect like this if metal-oxide-semiconductor quantity is more or caloric value when big.
Because described battery case 1 can effectively distribute the heat that metal-oxide-semiconductor 41 produces, a large amount of heats does not reassociate on the described metal-oxide-semiconductor 41; Because described metal-oxide-semiconductor 41 no longer directly is installed on the battery protecting circuit 31, but and keep certain interval between the battery protecting circuit 31, described metal-oxide-semiconductor can not conduct heat on the battery protecting circuit 31 yet.Therefore when lithium ion battery was worked, described metal-oxide-semiconductor 41 and battery protecting circuit 31 had effectively been avoided the variety of issue that causes owing to temperature is too high all keeping normal temperature.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
