Abstract
The utility model discloses a concave-convex groove battery case which relates to a battery device. The concave-convex groove battery case is characterized in that a plurality of concave-convex grooves are arranged on the wall of a battery case body. Compared with the prior art, the concave-convex groove battery case has the following advantages: 1. the battery case facilitates the exterior heat dissipation of batteries, and when a plurality of batteries are combined, a certain gap on the external surface of the battery case brings about good heat dissipation effect; 2. the battery case facilitates the electrolyte infiltration inside the batteries, and a certain gap exists between battery pole pieces and the case wall and the electrolyte can infiltrate, thereby improving the charging and discharging efficiency of the batteries, and prolonging the service life; and 3. the mechanical strength of the case body is reinforced, the case wall with the concave-convex grooves does not deform as easily as a flat case wall, thereby having high mechanical strength, relatively reducing the thickness of the case wall, saving material and reducing cost.
Description
Technical field
The utility model relates to a kind of cell apparatus, is specifically related to secondary rechargeable battery, comprises NI-G rectangular cell and ni-mh rectangular cell.
Background technology
At present, the ni-mh rectangular cell shell outer surface of known prior art, a kind of is straight smooth outer surface, and when a plurality of batteries carried out parallel connection or tandem compound, outer surface was close together mutually, heating is difficult to distribute when battery uses, cause inner pressure of battery big, capacity descends, and shortens the life-span, easy burn-out battery or power consumption equipment have an accident when serious; Two kinds is the outer surface of band salient point, though radiating effect is better, inside is the plane, and battery pole piece is close to shell wall after expanding, and the electric liquid of the inside is difficult for infiltration, neither optimum efficiency.Very inconvenient during use.
Summary of the invention
In order to overcome above-mentioned deficiency, the purpose of this utility model provides the battery case that a kind of appearance has tongue and groove, just can reach good heat dissipation effect, and interior pressure is little, capacity big and life-saving and the difficult purpose of permeating of electric liquid.It can be when a plurality of battery combination, and the outer surface of battery case has a fixed gap, good heat dissipation effect; And the pole piece of inside battery and shell wall have a fixed gap, and electric liquid can permeate, and help improving battery efficiency, life-saving; Increase the shell mechanical strength simultaneously, reduce shell thickness relatively, economical with materials reduces cost.
The technical scheme in the invention for solving the technical problem is: the tongue and groove battery case by battery container and battery shell wall are formed is characterized in that: the shell wall of battery container is provided with some tongue and grooves.
Above-mentioned tongue and groove can be multiple geometries such as trapezoidal, circle or triangle, and arranges in order, and arrangement mode comprises level, oblique angle, vertical.
Above-mentioned housing is square.
The utility model compared with prior art has following advantage:
1. help the outside batteries heat radiation.When a plurality of battery combination, the outer surface of battery case has a fixed gap, good heat dissipation effect.
2. help the infiltration of inside battery electricity liquid.Battery pole piece and shell wall have a fixed gap, and electric liquid can permeate, and help improving battery efficiency, life-saving.
3. increase the housing mechanical strength.Have the shell wall of tongue and groove more not yielding than straight shell wall, the mechanical strength height can reduce shell thickness relatively, and economical with materials reduces cost.
The invention has the beneficial effects as follows: simple in structure, easy to use, to save cost, efficiency for charge-discharge height, life-span long.
