Embodiment
For above-described content of the present invention, below in conjunction with concrete battery module heat dissipation design example, and specify in conjunction with picture.The battery module heat dissipation design example of the following stated belongs to category of the present invention, but does not comprise that all meet the situation of the scope of claim of the present invention.
The present invention is directed to the parallel air channel by the battery module of the elongate in shape of rectangular cell monomer composition, this battery module is arranged by a plurality of rectangular cell monomers and is formed, with the heat dissipation wind channel that is separated out between grid between battery.The present invention has proposed two kinds of effectively improvement methods for designing to the air channel of this battery module.
At first do an elaboration for problem: as shown in Figure 1, the strip power brick is comprised of 20 to 40 battery cores, and the air channel that is separated out between grid is arranged between the battery core, and air intake vent and air outlet be at two of battery module, employing be the radiating mode that walks abreast.
That the speed in exit is about 7 meter per seconds without any the distribution situation of the situation Fluid field of dividing plate, the speed of porch is slow, on average be about 1 meter per second, wind speed widely different, and may have some backflows near air channel between the battery of porch in the situation that entrance is limited.So generally speaking the wind speed profile of runner is very inhomogeneous between each battery.
This inhomogeneous wind speed profile meeting is so that the battery radiating condition is very inconsistent, directly caused a great difference of temperature in the course of work of battery.
So the present invention proposes the heat dissipation wind channel project organization:
With wind inlet channel or the air-out air channel interior welds baffle plate of long strip type battery module, it is divided equally, such as being divided into 2 or 3 sub-air inlet ducts or sub-exhaust passage.
If this method is all adopted in wind inlet channel and air-out air channel, namely form the essentially identical submodule of several number of batteries, be equivalent to long strip type battery module and air channel and be divided into together several independently cooling systems, improved the consistency of each single body radiating of module, made bringing into play at each submodule that the ability of blower fan tends to balance.
If only at wind inlet channel or only adopt this baffle plate to separate the air channel in the air-out air channel, can improve equally the consistency in flow field, because also can make like this bringing into play at each submodule that the ability of blower fan tends to balance.
In order further to improve the flow field consistency in air channel, the present invention also proposes the second Duct design structure, it is characterized in that being clipped between wind inlet channel (perhaps/and air-out air channel) and the battery module to come the wind speed of runner between each battery is adjusted with a kind of innovative dividing plate.The feature of this dividing plate is to dig out the slit that a width gradually changes at a plate.Owing to having reduced the area of the air intake at module rear portion, changed the static pressure distribution in inside modules air channel, thereby improved initial designs near the excessive problem of wind speed in the runner between the battery of exit.Adopt this dividing plate the uniformity coefficient of runner air velocity between the inside modules battery further to be promoted.
The another kind of form of the second project organization:
Dividing plate adopts porous hollow out form, is the slit hollow outs of using different sizes for the position in air channel between different batteries specifically, the area of these hollow outs, and direction is seen from the inlet to the outlet, totally presents the trend that reduces.Can be chosen in the porch adopts the mode in folding air channel to strengthening near the flow velocity in the runner between the battery of porch.The benefit that adopts this improved procedure be can be more careful the adjustment flow field.
For the method for designing of the combining form of all above two kinds of Duct design methods, all fall into the scope of claim of the present invention.
Initial Basic Design as shown in Figure 2, there are respectively wind inlet channel 2-1 and air-out air channel 2-2 in the battery pack both sides.The flow pattern of initial Basic Design is fast apart from the wind speed of runner between the nearer battery in exit, and slow apart from the wind speed of runner between the near battery in porch, whole wind speed profile is very inhomogeneous.
The first Duct design example as shown in Figure 4.All adopt dividing plate to be divided into three parts wind inlet channel 4-1 and air-out air channel 4-2, as shown in Figure 3.Can find out from the result of flow field simulation, flow field uniformity is improved.And then improved the consistency of whole Temperature Distribution.
The second Duct design example as shown in Figure 6.Adding lastblock between wind inlet channel 6-1 and battery module has the dividing plate 6-2 in the slit that width gradually changes.The shape of this piece dividing plate as shown in Figure 5.Air-out air channel 6-3 is with the structure in three minutes air channels shown in Figure 3.Can find out from the fluid simulation result, the consistency of the wind speed profile of battery module has obtained good improvement.
The third Duct design example as shown in Figure 8.It is characterized in that between wind inlet channel 8-1 and battery module, adding the dividing plate 8-2 that lastblock has different big or small hollow holes.The size in the hollow out slit on the dividing plate 8-2 reduces to air outlet position gradually from battery module air intake vent position, as shown in Figure 7.Air-out air channel 8-3 is exactly a simple passage.The part of the close entrance of wind inlet channel 8-1 has been carried out folding processing, and purpose is to improve the flow in the runner between near the battery of entrance.The wind speed consistency that can find out battery module from the fluid simulation result has obtained good improvement.The air velocity of runner concentrates on 3 to 4 meter per seconds basically between battery, is evenly distributed.Wind speed was fast in the middle of integral body presented, the feature that two wind speed is slightly slow, and this also meets the conforming requirement of heat radiation, because in theory under the equal radiating condition, intermediate cell heat.
The benefit of this Duct design example is the air-out air channel not to be divided equally, and has reduced the complexity of structure, and has obtained good wind speed consistency.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do anyly be equal to change or modify, all fall into the scope that this patent comprises.
