Abstract

The utility model relates to a lithium battery pack comprising a shell. The battery pack is formed by a plurality of single batteries through series connection and parallel connection. A through hole groove used for being fixed on a rod-shaped structure is arranged in the middle of the battery pack, the battery pack is provided with a plurality of mutually parallel air channels, the trend of the air channels is consistent with the direction of the length of the single batteries, and the air channels are surrounded by the outer walls of at least three single batteries through mutual connection. With passages surrounded by the outer walls of the single batteries through connection as cooling air channels, additional equipment does not need to be added, the structure is simple, and the cooling effect is good. According to the lithium battery pack, the through hole groove is formed in the middle of the battery pack, the lithium battery pack is sleeved on the rod-shaped structure and fixed during installation, and then the lithium battery pack can be combined with a product into a whole and space usage of the lithium battery pack is smaller.

Description

A kind of lithium battery group
Technical field
The utility model relates to lithium battery group.
Background technology
The shape of existing lithium battery group is generally regular geometry, the cell in lithium battery group be arranged as regular.Although such lithium battery group takes up room little, but be but difficult to install in some special occasion, as lithium battery group need to being fixed on to rod-like structure when, these batteries are fixed by bandage often, so not only take up room, and entirety is born larger vibration.Existing lithium battery group lacks radiator structure in addition, and the lithium battery group leader phase is operated under hot environment, can make the lost of life of battery pack.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of lithium battery group, and radiating effect is good, and is provided with through-hole groove in the middle of battery pack, is convenient to be fixedly mounted in rod-like structure, and space availability ratio is higher.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of lithium battery group, comprise housing, described battery pack is formed by series and parallel connections by some cells, in the middle of described battery pack, be provided with for being fixed on the through-hole groove in rod-like structure, described battery pack is provided with some air channels that are parallel to each other, and the trend in described air channel is consistent with the length direction of cell, and described air channel is interconnected and surrounded by the outer wall of at least three cells.The utility model is provided with through-hole groove in the middle of battery pack, when installation, lithium battery group is enclosed within rod-like structure and is fixed, and lithium battery group can be combined into one with product, and the shared space of lithium battery group is less; The vibration that the lithium battery group of this kind of mounting structure is subject to is less.In addition, radiating principle of the present utility model: the outer wall of using cell connects the passage surrounding as heat dissipation wind channel, without adding extra equipment, simple in structure; Natural wind can enter by the through hole from housing, after a part of natural wind enters, can enter air channel, walks and the heat of cell inner surface in air channel is taken away along air channel; The natural wind of another part can be walked in battery pack periphery, thereby the heat of cell outer surface is taken away; Through the natural wind of heat exchange finally can be in air channel towards another one get back to the external world by eliminatings, thereby form the wind path of a circulation, can effectively solve the problem that in housing, battery pack is dispelled the heat.
As improvement, the one side that described housing is relative with air channel is provided with the perforation corresponding with described through-hole groove and the ventilation hole corresponding with described air channel.
The beneficial effect that the utility model compared with prior art brought is:
The outer wall of using cell connects the passage surrounding as heat dissipation wind channel, without adding extra equipment, simple in structure, good heat dissipation effect.The utility model is provided with through-hole groove in the middle of battery pack, when installation, lithium battery group is enclosed within rod-like structure and is fixed, and lithium battery group can be combined into one with product, and the shared space of lithium battery group is less.
Accompanying drawing explanation
Fig. 1 is lithium battery group end face structure schematic diagram.
Fig. 2 is housing side structural representation.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of lithium battery group, comprises housing 2, and lithium battery is mounted in housing 2.Described lithium battery group 1 is formed by series and parallel connections by some cells 3, in the middle of described battery pack 1, be provided with for being fixed on the through-hole groove 5 in rod-like structure, described battery pack 1 is provided with some air channels that are parallel to each other 4, the trend in described air channel 4 is consistent with the length direction of cell 3, and described air channel 4 is interconnected and surrounded by the outer wall of at least three cells 3.Described housing 2 one side relative with air channel 4 is provided with the perforation 6 corresponding with described through-hole groove 5 and the ventilation hole 7 corresponding with described air channel 4.
The utility model is provided with through-hole groove 5 in the middle of battery pack 1, when installation, lithium battery group 1 is enclosed within rod-like structure and is fixed, and lithium battery group 1 can be combined into one with product, and the shared space of lithium battery group 1 is less; The vibration that the lithium battery group 1 of this kind of mounting structure is subject to is less.In addition, radiating principle of the present utility model: the outer wall of using cell 3 connects the passage surrounding as heat dissipation wind channel 4, without adding extra equipment, simple in structure; Natural wind can enter by the through hole from housing 2, after a part of natural wind enters, can enter air channel 4, walks and the heat of interior air channel 4 cell 3 inner surfaces is taken away along air channel 4; The natural wind of another part can be walked in battery pack 1 periphery, thereby the heat of cell 3 outer surfaces is taken away; Through the natural wind of heat exchange finally can be in air channel 4 towards another one get back to the external world by eliminatings, thereby form the wind path of a circulation, can effectively solve the problem that the interior battery pack 1 of housing 2 is dispelled the heat.
