Abstract

The utility model discloses an NI-MH (nickel-metal hydride) battery with a heat dissipation function, which aims at solving the problems of an existing NI-MH battery that the using effect and the service life of the battery are affected due to lack of natural heat dissipation in the battery. The NI-MH battery is characterized in that heat dissipation plates (3) are arranged between a positive electrode plate (7) and a membrane (6) as well as between a negative electrode plate (5) and the membrane (6), which are arranged in the middle in a shell; two edges of each heat dissipation plate (3) are connected with the inner side surfaces of a lower electrode pole (2) and a side collector plate (4), respectively. Therefore, the NI-MH battery has the advantages that an excellent heat dissipation effect is achieved, the service life of the battery is prolonged, and the like.

Description

A kind of Ni-MH battery with heat sinking function
Technical field
The utility model relates to a kind of battery, relates in particular to a kind of Ni-MH battery with heat sinking function being comprised of housing, battery cover, upper pole, lower pole, positive plate, negative plate, side collector plate and barrier film.
Background technology
Electrokinetic cell has been widely used in the electric machines such as the vehicles, daily living article, because the heat producing in electrokinetic cell can impact the use of electrokinetic cell, in order to reduce electrokinetic cell, in use can produce a large amount of heats, electrokinetic cell mainly adopts the mode of air-cooled or water-cooled to dispel the heat to electrokinetic cell in the market, but this radiating mode is just better to battery appearance temperature heat radiation situation.And the inner heat producing of electrokinetic cell is difficult to the heat that is dispersed into outside or is transmitted to outside batteries seldom, therefore adopt external cooling mode poor to the radiating effect of the heat of inside battery generation, owing to really affect the temperature factor of battery performance, be the temperature of inside battery again, therefore this radiating mode cannot fundamentally solve the impact that the heat of inside battery generation causes battery performance.In addition, the natural conditions such as weather, region, the temperature difference, environment are also the key factors of radiating effect of the external refrigeration radiating mode of restriction electrokinetic cell.Especially on to the heat radiation of great-capacity power battery, radiating effect affects result of use and the useful life of battery self more.Moreover, in the market, can effectively measure device more complicated all of the internal temperature of electrokinetic cell, the testing cost of electrokinetic cell is increased, thereby caused for the increase to the maintenance costs of electrokinetic cell, and then the use cost of electrokinetic cell is increased.
Summary of the invention
The purpose of this utility model is to provide a kind of electrokinetic cell with heat sinking function, is intended to solve the Ni-MH battery with heat sinking function that prior art medium power inside battery cannot natural heat dissipation.
For achieving the above object, a kind of Ni-MH battery with heat sinking function of the utility model, comprise housing, battery cover, upper pole, lower pole, positive plate, negative plate, side collector plate and barrier film, between positive plate and negative plate, be provided with barrier film, by positive plate, negative plate and barrier film are placed in housing, upper pole is connected and lower pole is placed in housing with lower pole through battery cover, lower pole is arranged to cross section and is L shape, the one side of lower pole is connected with upper pole, the another side of lower pole is connected with side collector plate upper end, side collector plate is connected with a plurality of positive plates or a plurality of negative plate, in described housing, between the positive plate at middle part and barrier film and negative plate, be provided with heating panel, the both sides of heating panel are connected with side collector plate inner surface with lower pole respectively.
Tilting respectively on described heating panel two surfaces have many to be convenient to the groove being parallel to each other that electrolyte passes through, between groove and groove, leave prescribed distance, between adjacent two grooves, be provided with prismatic through hole, be convenient to electrolyte and flow between positive plate and negative plate.
Another lip-deep many grooves of lip-deep many grooves of described heating panel one and heating panel are arranged in a crossed manner.
Adopt after this structure, due in described housing middle part positive plate and barrier film and negative plate between be provided with heating panel, the both sides of heating panel are connected with side collector plate inner surface with lower pole respectively.Therefore, reach and solve the object that prior art medium power inside battery cannot natural heat dissipation.
