Abstract
The utility model relates to a battery block, which mainly aims at solving the problems that the radiating is difficult existing in the prior art. The utility model comprises a shell body and battery cells, wherein, the shell body is provided with an opening, and a fan is arranged in the shell body; the battery cells are a plurality of superposed battery cells connected in series and parallel, a supporting structure for making the battery cells have certain clearance is arranged between the battery cells. As the shell body of the utility model is provided with an opening, the heat energy produced during the charge and discharge will be discharged immediately, thus heat assembly will not be produced; the fan is arranged in the shell body, which forcibly discharges the heat energy in the battery block and accelerates the discharge of the heat energy; as the supporting structure for making the battery cells have certain clearance is arranged between the battery cells, an airflow channel is formed between the battery cells, which is more beneficial for the discharge of the heat energy.
Description
Technical field
The utility model relates to a kind of battery block, particularly the radiator structure of battery block.
Background technology
Along with movable electrical appliances, as a large amount of uses of mobile phone, Hand Personal Computer and mobile audio and video equipment etc., battery block is as energy supplier, and it uses more and more widely, and the capacity of battery block is also in continuous growth.Battery block is in charge and discharge process, can produce certain heat, and the capacity of battery is high more, the heat that produces in unit interval is many more, these heats such as untimely discharge can be in the battery block inner accumulated, in the inner high-temperature region that forms of battery block, influence the serviceability and the security performance of battery block, may influence near the operating state of the electronic unit of battery block simultaneously; Existing battery contains housing and electric core, the electricity core is installed in the housing, be connected with electric conductor between housing and electric core, make the electric core can the external charge circuit or be connected with load, the battery block of this structure can be finished the basic function that discharges and recharges, but does not have heat abstractor, influence the serviceability and the security performance of battery block, also influence near the operating state of the electronic unit of battery block.
The utility model content
The purpose of this utility model is to provide a kind of battery block, can dispel the heat, and can guarantee the normal use and the safety of battery block, makes near the electronic unit of battery block be in normal operating state; Its further purpose is to improve radiating efficiency.
A kind of battery block described in the utility model contains housing and electric core, has opening on housing;
Fan is housed in housing;
Described electric core is a plurality of series-parallel superimposed electric cores, is equipped with between electric core and electric core and makes the supporting construction that has certain interval between electric core.
Because a kind of battery block described in the utility model, opening is arranged on housing, the heat that produces in charge and discharge process can in time be discharged, can not produce heat accumulation, fan is housed in housing, can carry out forced-ventilated the heat in the battery block, quicken to discharge heat, between electric core and electric core, be equipped with and make the supporting construction that has certain interval between electric core, can between electric core and electric core, form gas channel, be more conducive to heat and discharge.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is a profile of the present utility model.
Embodiment
A kind of battery block described in the utility model as Fig. 1, contains housing 1 and electric core 2, has opening 3 on housing 1; Described opening 3 can be the grooved opening, also can be a plurality of holes that are distributed on the housing 1.
Fan 4 is housed in housing 1, and as Fig. 3, fan 4 is fixed on the housing 1 by syndeton, and is loaded near the described opening 3, and fan 4 is connected on the electric core 2 of battery block, with the power supply drive of battery block itself;
Described electric core 2 is a plurality of series-parallel superimposed electric cores, as Fig. 2, at electric core 2 and 2 in electric core the supporting construction 5 that makes 2 in electric core have certain interval is housed, and forms gas channel in the gap of 2 existence of electric core, and the heat that electric core 2 is produced is discharged more swimmingly; Described supporting construction can be the plastic strip that is affixed between electric core, also can be a plurality of two-sided blob of viscose of lining up dot matrix.
On housing 1, be inlaid with sheet metal 6 or metal tape, as Fig. 1,2.Sheet metal 6 is embedded on the plastic cement shell, and sheet metal can be separately, also can be to connect on sheet.
The battery made from the utility model against existing technologies below compares its performance:
Three joints are full of the overlapping series connection of polymer Li-ion battery (size 0.5 * 80 * 130) of the 4800mA of electricity; after adding baffle; in the plastic cement shell that the edge that sets aside does not punch; carry out discharge test; discharging current is 2400mA and 4800mA etc., sandwiches thermocouple in two-layer, measures temperature (the heat idol is positioned at centre); carry out four groups of parallel tests altogether, result such as table 1:
| Temperature | One group | Two groups | Three groups | Four groups |
| 2400 | 62℃ | 66℃ | 60℃ | 63℃ |
| 4800 | 85℃ | 81℃ | 88℃ | 83℃ |
Example 1: all the other same Comparative Examples, just between three economize on electricity cores, add a two-sided heat-conducting glue (thick 1mm) every 30mm, with the 4800mA discharge, the test thermal effect.Thermal effect test is to adopt inside temperature measurement to carry out, and adopting instrument is digital display HFT-80 type thermo detector, during measurement, the probe of thermo detector is inserted between the two superimposed electric cores.
Example 2: all the other are with example 1, just on the external packing plastic cement shell with to stamp each four row's diameter be the ventilation hole of 2mm on the back side of electric core ventilating opening relative position and plastic cement shell, with the 4800mA discharge, the test thermal effect.
Example 3: all the other just load onto a mini-fan with example 2 on plastic cement shell termination.With the 4800mA discharge, the test thermal effect.
Result of the test such as following table:
