Description
Technical field
The present invention relates to cell apparatus, specifically, relate to a kind of high heat dissipation battery/set of cells.
Background technology
The heat abstractor of battery is one of key factor affecting battery operated efficiency.Temperature affects of both having battery: first, and along with the rising of temperature, the internal resistance of battery reduces, thus improves the discharging efficiency of battery；Second, higher temperature accelerates electrode chemical reaction, chemical reaction rate and temperature and becomes Series Relations, and temperature increases by 10 DEG C, and chemical reaction rate doubles, but also accelerates side reaction simultaneously, and battery structure is produced permanent damages.Additionally, the fragile battery pole plates of high temperature and generation overcharge phenomenon, have a strong impact on battery life.And at low ambient temperatures, the internal resistance of battery is greatly increased, discharge capacity significantly reduces, and during charging, intrinsic pressure rising is accelerated, and now battery has potential potential safety hazard.Therefore, keeping the relative constancy of temperature in cell operations is to maintain battery performance, an importance of prolongation battery.
Battery is respectively provided with optimum working temperature scope, the optimum working temperature scope of such as Ni-MH battery is 20 ~ 40 DEG C, and due to the reason such as environmental factors and heat conduction condition, the operating temperature of battery can exceed that this scope, therefore, the heat management of battery is extremely important.At present the battery thermal management of application specifically includes that air-cooled, liquid cooling, thermoelectric-cooled, heat pipe cool down and the various ways such as phase-change material.
The battery of prior art there is problems in that when set of cells works in parallel or series, owing to battery case is that smooth surface is arranged in order and sticks together, the heat distribution causing battery is uneven, affects radiating efficiency, cause battery-heating, have a strong impact on battery life.The key factor that the heat dissipation design of efficient uniform considers when being to improve Ni-MH battery discharging efficiency and life-span.
Summary of the invention
The problem to be solved in the present invention is, for the defect that battery thermal diffusivity is the best, it is provided that a kind of improves heat transfer efficiency, improve the battery/set of cells of battery uniform heat distribution.
The technical solution used in the present invention: construct a kind of high heat dissipation battery/set of cells, including shell, it is provided with positive negative terminal on the housing and in described shell, is provided with battery/battery pack body, form gap between described shell and battery/battery pack body, described gap is filled with heat conduction glue-line；Auxiliary heat dissipation is carried out by fan between described battery/battery pack body.
In battery/set of cells of the present invention, described shell is aluminum shell or stainless steel casing.
In battery/set of cells of the present invention, described heat-conducting glue is normal temperature cure silicone heat-conducting glue.
In battery/set of cells of the present invention, the thickness of described heat conduction glue-line is 1 ~ 3mm.
In battery/set of cells of the present invention, the shape of described shell is cuboid.
The present invention compared with prior art has the advantage that
Heat-conducting glue between this battery case and battery/battery pack body can improve the uniform heat distribution that battery is overall, improve radiating state, and the face contact that the hemisphere jut of battery case outer surface is prevented between battery case, reduce the battery temperature rising that heat build-up causes, extend the service life of battery.

Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
The present invention is described further below in conjunction with the accompanying drawings.
High heat dissipation battery/the set of cells of one as shown in Figure 1, including shell 1, described shell 1 it is provided with positive negative terminal 2,3 and in described shell, is provided with battery/battery pack body 4, forming gap between described shell 1 and battery/battery pack body 4, described gap is filled with heat conduction glue-line；Auxiliary heat dissipation is carried out by fan between described battery/battery pack body.
In battery/set of cells of the present invention, described shell 1 is aluminum shell or stainless steel casing.
In battery/set of cells of the present invention, described heat-conducting glue is normal temperature cure silicone heat-conducting glue.
In battery/set of cells of the present invention, the thickness of described heat conduction glue-line is 1 ~ 3mm.
In battery/set of cells of the present invention, the shape of described shell 1 is cuboid.
Battery of the present invention is to work in the way of serial or parallel connection composition set of cells.The assembling mode of set of cells is: be stacked (rationally can stack according to the concrete shape of battery) by several battery modules, form an independent unit, several unit vertical stacks one independent set of cells of composition, set of cells is integrally attached on fixed charge method end plate, two ends are provided with aerofoil fan entirety and battery are carried out auxiliary heat dissipation, although set of cells overall structure is the compactest, but owing to battery case is protruding and the existence of through hole, also can form suitable air channel, thus meet the requirement of heat radiation.
