Case.
2nd, background technology
Power battery pack is the energy accumulating device of new-energy automobile, long in vehicle traveling process and park charging process
Time is in running order.Battery pack can continue that electrochemical reaction and physical reactions occur during charging and discharging, produce
Substantial amounts of heat energy, so as to cause battery pack temperature to rise, influence the performance and used life of battery pack.On the one hand, battery pack has
One optimum working temperature scope, when battery cell temperature is higher than the scope, its electrochemical reaction limit can change, and enter
And influence charge/discharge capacity, internal resistance and the cycle life of battery cell；On the other hand, due to different battery cells and same electricity
The radiating condition of pond monomer different parts is different, and internal battery pack occurs the even phenomenon of temperature distributing disproportionation, causes not equality of temperature
The battery cell of degree shows different performance characteristics, and the interaction between them can make some battery cells in discharge and recharge
Reach blanking voltage in journey in advance, so that the efficiency for charge-discharge of battery pack declines, ultimately result in entering for whole battery performance
One step reduces.Therefore, it is necessary to carry out reasonable, effective heat dissipation design to automobile power cell case, integrally dissipated in guarantee battery pack
While hot speed, make the radiating of each battery cell more uniform.
The common heat-removal modalities of automobile power cell are based on air-cooled and water-cooling at present, battery thermal management system of arranging in pairs or groups
In use, the bulk temperature of battery pack can be effectively reduced.But because the design space on automobile is limited, battery cell is usual
Need to be closely spaced in battery case, therefore the radiating of each battery cell is not uniform enough.If it is separated by using by battery cell
Certain distance is distributed across the method in battery case, can significantly increase battery case volume again.Find by literature search, in
Patent Office of State Intellectual Property Office of state discloses a Publication No. CN105742540A on July 6th, 2016, and entitled " one
The patent application of the power battery box of electric vehicle of kind high efficiency and heat radiation ".The technology is provided with some use side by side in Battery case
In the battery grid of placing battery monomer, it is desirable to which the upper surface of grid forms not higher than edge on cell, and with battery cell
Power battery module, power battery module can all installed in one layer of battery case bottom plate, by with leading on bottom plate closed surface
Hot silica gel or heat conductive pad radiating, can also divide two layers of installation in battery case, and lower floor's power battery module is arranged on battery case bottom

One end installation cooling fan 9 of the passage of heat 12, corresponding other end mounting temperature sensor 8；One end of installation cooling fan 9 leads to
The heat emission hole 1-3 and intake stack 10 for crossing outer battery case are bolted to connection, and one end of mounting temperature sensor 8 passes through outer
The heat emission hole 1-3 of battery case is bolted to connection with wind pipe 11, forms cooling system；Temperature sensor 8 and cooling
Fan 9 is connected with electronic control unit 7, is powered by power battery pack.
Interior battery case 3, one side connection radiating fin 2 and two-sided connection radiating fin 5 are made from a material that be thermally conductive, outer battery
Case 1 and outer battery box cover 6 are made by partiting thermal insulation material.
The running of the present invention：Interior battery case 3, one side connection radiating fin 2 and two-sided connection radiating fin 5 are by heat conduction
Material is made, and is brought into close contact with the surrounding of battery cell 4, and it is logical that heat caused by battery cell 4 can be rapidly transferred to radiating
Road 12.One side connection radiating fin 2 has the heat radiating fin wing 2-3 of rim of the mouth one side, two-sided with all composition radiating component assemblys
Constitute heat dissipation channel 12 between the heat radiating fin wing 5-2 at connection radiating fin edge, and with the heat emission hole 1-3 of outer battery case 1
Communicate；Cooling fan 9, corresponding other end mounting temperature sensor 8 are installed in one end of each longitudinal heat dissipation channel；Electronics control
Unit 7 processed monitors the air themperature of each outlet of heat dissipation channel 12 by temperature sensor 8 in real time, and real-time according to temperature information
The rotating speed of each cooling fan 9 is adjusted, the cooling fan rotation speed of each heat dissipation channel 12 can be with independent control.9 turns of cooling fan
Speed is faster, flows through that the air mass flow of heat dissipation channel 12 is bigger in the unit interval, and the rate of heat dispation of the heat dissipation channel 12 is faster.Cooling
System carries out radiating control by " team control " and " single control " both of which to battery pack.
Team control pattern：When the overall caloric value of battery pack is larger, it is logical that Heat Conduction Material can conduct heat to each radiating
Road 12 raises the temperature of each heat dissipation channel 12, and temperature sensor 8 detects each outlet temperature of heat dissipation channel 12 and will letter
Breath passes to electronic control unit 7, electronic control unit 7 by read temperature information judge the overall caloric value of battery pack compared with
Greatly, the integral heat sink speed of battery pack is improved after data processing by improving the rotating speed of all porch fans 9 of heat dissipation channel 12,
So as to obtain good integral heat sink effect, the control targe of team control pattern is to reduce the mean temperature of each heat dissipation channel 12.
Single control pattern：When the temperature of each battery cell 4 in battery pack is inconsistent, Heat Conduction Material can conduct heat to
Each heat dissipation channel, raise the temperature of heat dissipation channel 12 near the higher battery cell 4 of temperature.Temperature sensor 8 detects respectively
The temperature in the individual exit of heat dissipation channel 12 simultaneously passes information to electronic control unit 7, and electronic control unit 7 is by reading temperature
Information obtains the temperature data of each heat dissipation channel 12, heat dissipation channel 12 porch higher by improving temperature after data processing
The rotating speed of fan 9 improves the rate of heat dispation of the heat dissipation channel 12, so as to reduce the temperature of the heat dissipation channel 12.When each radiating is logical
The temperature in road 12 close to it is consistent when, the interior battery case 3 that is made from a material that be thermally conductive, two-sided connection radiating fin 5, one side connection radiating
The temperature of fin 2 and each battery cell 4 is also close to consistent, so as to obtain good heat dissipation uniformity, the control of single control pattern
Target is to make the temperature of each heat dissipation channel 12 identical.
