Abstract
The invention relates to a finned single cell structure for an electric automobile. The finned single cell structure is composed of an electrode, a cell substrate, convex plates and concave grooves. Side surfaces of the shell of the single cell are provided with the convex plates and the concave grooves which are in staggered parallel arrangement; both the convex plates and the concave grooves form an angle of 0-90 degrees with the bottom surface of the cell; proportion values of the width of the concave grooves to the width of the convex plates range from 1 to 5; and the width values of the convex plates range from 2 mm to 10 mm. Through the design of the finned single cell structure, disturbance when a heat transfer fluid flows through two adjacent single cells of a power battery pack; heat transfer coefficient is increased; and at the same time, finned coefficient of the surface of the shell of the single cell is increased; heat transfer area on the surface of the shell is increased greatly and a heat transfer effect is significantly increased, thereby enabling the single cell to be cooled or heated rapidly.
Description
Technical field
Relate to new-energy automobile electrokinetic cell field, be specifically related to pure electric automobile or Hybrid Vehicle cell structure.
Background technology
The key problem in technology of electric automobile is an electrokinetic cell, and the quality of electrokinetic cell performance has directly determined the electric automobile future market prospect.Because electrokinetic cell can discharge a large amount of heat in charge and discharge process, cause the temperature of power brick to rise, can directly influence the serviceability and the life-span of battery, temperature is too high then may to cause security incident; In addition, cross when low, also need electrokinetic cell is carried out heat treated, to improve its serviceability in temperature.
To adopt air or liquid be the heat radiation and the heating of medium to Kai Fa used for electric vehicle electrokinetic cell more in the market, and it mainly is to be undertaken by the heat convection or the heat conduction form of medium and battery surface that heat or cold conduct heat.The electrokinetic cell structure of electric automobile use now mostly is cuboid or cylinder, and its heat-transfer surface is smooth side.From the angle of conducting heat, the smooth heat-transfer surface of rule is strengthened can not effectively improve heat output, to the rapid heat radiation of electric automobile power battery and heat unfavorable.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of area of dissipation big, the used for electric vehicle rib-type cell structure that heat exchange coefficient is high.
The present invention adopts following technical scheme:
A kind of used for electric vehicle rib-type cell structure, form by electrode, battery matrix, boss, groove, it is characterized in that: cell case side mask has staggered boss and the groove that is arranged in parallel, and boss all becomes 0 °～90 ° angles with groove with battery matrix bottom surface.
Described recess width and boss width ratio value scope are 1～5, and boss width value scope is 2-10mm.
Compared with prior art, this used for electric vehicle rib-type cell structure has following advantage:
(1) the present invention is provided with staggered boss and the groove that is arranged in parallel in cell housing side, and the used for electric vehicle cell is designed to rib-type.In the time of in groups a plurality of rib-type cells are laterally neatly arranged in the same way, and left less gap between the rib-type cell.Fluid flows through battery container staggered boss in surface and the groove tortuous runner that wrong row forms in the battery container both sides in the battery pack, disturbance when having strengthened heat exchanging fluid and flowing through in the power battery pack cell gap in twos, improve heat exchange coefficient, strengthened heat-transfer effect.
(2) simultaneously, by gilled structural design, make the inned coefficient of cell surface of shell increase, the surface of shell heat transfer area greatly increases, also significantly increased heat output, reached the purpose of augmentation of heat transfer, made cell can obtain heat radiation or heating rapidly.。

Embodiment
A kind of used for electric vehicle rib-type cell structure as shown in Figure 1, is made up of electrode 1, battery matrix 2, boss 3, groove 4.Cell case side mask has staggered boss 3 and the groove 4 that is arranged in parallel, and boss 3 all becomes 0 °～90 ° angles with groove 4 with battery matrix 2 bottom surfaces, get 30 ° in the present embodiment.
The rib-type cell of this example be shaped as cuboid.Boss 3 and groove 4 are arranged on two maximum sides of cuboid, and boss 3 on the two sides and groove 4 dislocation are arranged.
On the electric automobile power battery assembly structure, 2～10 horizontal proper alignment of cell are formed a battery module, be joined together to form series connection by electrode connection 5, as Fig. 2, shown in Figure 3, the cell number gets 5 in the present embodiment battery module; Interval 2-10mm between the cell in the battery module, present embodiment is got 5mm at interval.The vertical proper alignment of a plurality of battery modules is formed a battery pack place battery box 6, as shown in Figure 4, power taking pond module is got 4 in the present embodiment battery pack.
In the electric automobile power battery use, when temperature is higher than a certain design temperature, during as 40 ℃, start radiating mode, cold air or liquid medium pass the tortuous passageway outflow of cell group and take away the heat of battery.Since the staggered boss 3 in battery container surface and 4 pairs of coolants of groove force disturbance, the disturbance when having strengthened heat exchanging fluid and flowing through in the power battery pack cell gap has in twos improved heat exchange coefficient, has strengthened heat-transfer effect.Simultaneously, by gilled structural design, make the inned coefficient of cell surface of shell increase, the surface of shell heat transfer area greatly increases, and has also significantly increased heat output, has reached the purpose of augmentation of heat transfer.
Be lower than a certain design temperature as temperature in the use, as using in the winter time, temperature is lower than 0 ℃, then starts heating mode, and the tortuous passageway that the air of heat or liquid medium pass the cell group flows out and take away the heat of battery.Equally, battery container staggered boss 3 in surface and groove 4 have also formed heating efficiently, have reached the purpose of augmentation of heat transfer, make cell can obtain heat radiation or heating rapidly.。
In the present embodiment, the staggered boss 3 in cell housing both sides and groove 4 and battery matrix 2 bottom surfaces at an angle of 90, as Fig. 5-shown in Figure 8.Other are identical with embodiment 1.Present embodiment is more suitable for the heat radiation of battery pack when horizontal direction of ventilation.
In the present embodiment, the staggered boss 3 in cell housing both sides becomes 0 ° of angle with groove 4 with battery matrix 2 bottom surfaces, as Fig. 5-shown in Figure 8.Other are identical with embodiment 1.Present embodiment is more suitable for the heat radiation of battery pack when vertical direction.
