Abstract
The utility model provides a battery core radiating structure for a large-capacity lithium battery. In the structure, a plurality of battery cores are arranged neatly, an I-shaped radiating fin is arranged between adjacent battery cores, and a [-shaped radiating fin is respectively arranged outside the battery cores at two ends. The radiating fins are aluminum sheets or aluminum alloy sheets preferentially, and steel wires tightened in spiral mode are arranged on the periphery of the integration of the battery cores and the radiating fins. The structure is used for assembling of the large-capacity lithium batteries, can radiate internal heat of the battery fast when the battery works under large current, effectively controls temperature of the battery, guarantees that the battery works safely and reliably, prolongs recycling service life of the battery, and is especially suitable for use requirements of electric tool products for the battery of being big in current and long in service life.
Description
Technical field
The utility model relates to lithium ion battery, particularly a kind of high-capacity lithium battery electricity core radiator structure.
Background technology
The low capacity lithium battery overwhelming majority is used in the accumulation energy type electronic products such as mobile phone, MP3 at present; Perhaps be applied in the electric vehicle system through the design capacity that adds macrocell; Along with the raising of technical matters level and widening of application, lithium ion battery progressively is applied in the electric tool (like hay mover, electric drill, electronic toy etc.).Because the electric tool product requirement has higher operating current; 5～10 multiplying powers that are generally rated capacity (are 5C～10C); So need make particular processing aspect battery design and the making; Topmost approach is to reduce the internal resistance of cell, improves electrode conductivuty, the radiating effect when strengthening heavy-current discharge.The package assembly of existing lithium battery electric core be adjacent electric core each other near, radiating mode does not deal with, radiating effect is poor, temperature is higher during big current work, causes it not reach the long-life instructions for use of big electric current.
The utility model content
The technical problem that the utility model will solve is the weak point that overcomes existing electric core structure of lithium battery, and a kind of enhancing radiating effect is provided, and satisfies the high-capacity lithium battery electricity core radiator structure of electric tool product instructions for use.
The technical scheme of the utility model is: high-capacity lithium battery electricity core radiator structure, and many electric core proper alignment, its improvements are to be provided with " I " type fin between the adjacent electric core, the outside of two ends electricity core is provided with " Contraband " type fin.
Said fin is aluminium flake or aluminum alloy sheet; The whole periphery of said electric core and fin is provided with the steel wire that spiral tightens up.
The beneficial effect of the utility model is: electric core radiator structure has been made important improvement; The electricity core is through the fin heat radiation, and fin shape has been done preferably obviously to improve radiating effect; Avoid internal heat to assemble during the big current work of battery, thereby satisfy the instructions for use of electric tool product.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Referring to accompanying drawing; Process lithium battery after many electric core 2 assemblings, be provided with " I " type fin 3 between the adjacent electric core, the outside of two ends electricity core is provided with " Contraband " type fin 1; The whole periphery of electricity core and fin is provided with the steel wire 4 that spiral tightens up, and above-mentioned fin is an aluminium flake.
Claims (3)
1. high-capacity lithium battery electricity core radiator structure, many electric core proper alignment is characterized in that being provided with between the adjacent electric core " I " type fin, and the outside of two ends electricity core is provided with " Contraband " type fin.
2. by the described high-capacity lithium battery electricity of claim 1 core radiator structure, it is characterized in that said fin is aluminium flake or aluminum alloy sheet.
3. by the described high-capacity lithium battery electricity of claim 1 core radiator structure, it is characterized in that the whole periphery of said electric core and fin is provided with the steel wire that spiral tightens up.
