Abstract
The utility model discloses a heat radiating structure of a lithium ion storage battery, which comprises a battery cover, a battery protection panel and heat radiating fins, wherein the battery protection panel is fixed on the inner wall at the top of the battery cover; the heat radiating fins comprise heat conducting ends and heat radiating ends, wherein the heat conducting ends are fixed on the battery protection panel; and the heat radiating ends penetrate through bar-shaped holes arranged on the battery cover and are exposed outside the battery. According to the utility model, the heat radiating issue of a field effect transistor of the battery protection panel in the charging and discharging processes is improved, the service life of the battery protection panel is prolonged, further the service life of the lithium oil storage battery for starting a motorcycle is prolonged, and the practicability of the lithium ion batteries is improved greatly.
Description
Technical field
The utility model relates to the battery technology field, relates in particular to a kind of motorcycle and works the radiator structure of employing lithium-ions battery.
Background technology
Motorcycle rises and employs lithium-ions battery is a kind of novel starting battery.With present technical merit, lithium-ions battery is overcharging or is having potential safety hazard during overdischarge.For improving safety in utilization; Must protective circuit be installed to lithium-ions battery, the overcharging of each cell in the monitoring battery group, cross put, states such as overcurrent, short circuit, excess temperature, the break-make in instant Control current loop; Thereby the protection battery, the useful life of prolongation battery.With present technology; When designing the protective circuit of lithium-ions battery, unavoidably to use FET (MOS switch), under high magnification charge and discharge state; FET can generate heat; Bad if dispel the heat, the temperature of FET will sharply rise, and finally cause FET to damage and lose protective effect.Therefore, lithium-ions battery must solve the heat dissipation problem of FET in the high power charging-discharging process.
The utility model content
The utility model has overcome deficiency of the prior art, provides a kind of motorcycle to work the radiator structure of employing lithium-ions battery, solves the heat dissipation problem of FET.
In order to realize above-mentioned purpose; Adopt following technical scheme: a kind of radiator structure of lithium-ions battery; Comprise battery cover, battery protecting plate and fin, said battery protecting plate is fixed on the battery cover top inner wall, and said fin comprises heat conduction end and radiating end; The heat conduction end is fixed on the battery protecting plate, and the bar hole that radiating end passes the battery cover setting exposes in the battery outside.The heat conduction end of fin is delivered to radiating end with the heat heat of battery protecting plate, and heat is dispersed into the battery external world, reduces the especially temperature of battery protecting plate of inside battery, plays the effect of protection, prolongs the useful life of battery.
Said fin is bent into groove-like for the convex sheet metal, and the convex upper end is the heat conduction end, and the convex lower end is a radiating end.Convex upper end area is less, and is easy for installation as the heat conduction end, also can on inside battery or battery protecting plate, not form obstacle.Convex lower end area is bigger, has increased area of dissipation as radiating end, improves radiating effect.
Said heat conduction end is adjacent to the FET heat radiation pin on the battery protecting plate, can reach the better protection effect to FET.
Said heat conduction end is provided with screw; Through screw the heat conduction end is fixed on the battery protecting plate; Said heat conduction end is connected on the battery protecting plate through heat-conductive bonding agent, and said radiating end is provided with screw, through screw or adhesive radiating end is fixed on the battery cover outer surface of cupular part.The mode that connects and fix is flexible, can take no method according to different needs.
The surface of said fin is concavo-convex or corrugated, to increase area of dissipation.The material of said fin is aluminium, copper, iron or wherein any alloy of arranging in pairs or groups, and further improves radiating effect.
Compared with prior art; The beneficial effect of the utility model is: the heat dissipation problem that improves battery protecting plate FET in the charge and discharge process; Prolonged the useful life of battery protecting plate; And then prolong motorcycle and work the useful life of employing lithium-ions battery, improved the practicality of this type of lithium-ions battery greatly.
