Background technique
Automobile is the big power consumer of industry, while being also important environomental pollution source.In energy shortages and environmental pollution
Dual-pressure under, people increasingly pay attention to the research and development and production of electric car.Power battery provides energy for power vehicle, very
Vehicle performance is determined in big degree.In electric car operational process, power battery generates greatly because chemical reaction occurs for inside
The heat of amount.If these heats cannot be taken away in time, increase temperature of powered cell, the final normal fortune for influencing electric car
Row, or even cause safety accident.In addition, the difference of the radiating condition of power battery causes the temperature difference of battery pack, longtime running will
The performance of battery pack is reduced, cell degradation is accelerated.In order to guarantee that power battery pack is safely and steadily run, it is suitable to need to develop
Power battery cooling system, efficiently takes away the heat that battery generates during the work time, control battery in suitable temperature and
Work in the temperature difference range.Currently, equidistant U-shaped parallel fluid channels air cooling system is the common battery cooling system of electric car
System.However, the design of equidistant parallel fluid channels is difficult to ensure the consistent cooling condition of power battery, battery pack presence is ultimately caused
Biggish hot(test)-spot temperature and the temperature difference hinder battery pack to play its optimum performance.
Utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming, provide a kind of for the non-etc. of power battery heat dissipation
Away from U-shaped runner air cooling system, while not increasing power consumption, the heat dissipation effect of battery cooling system is effectively improved.
What the purpose of this utility model was realized in.
It is a kind of for power battery heat dissipation the U-shaped runner air cooling system of non-equidistant, including import, import deflector,
Several coolant flow channels, outlet deflector, outlet and power battery pack, import, coolant flow channel, outlet are interconnected, import and institute
It states and is equipped with the import deflector between several coolant flow channels;Outlet deflector is equipped between several coolant flow channels and outlet;It is cold
But air enters cooling system by import, and coolant flow channel is entered under the action of import deflector;After coolant flow channel,
Converge under the action of outlet deflector, leaves cooling system finally by outlet;Spacing, that is, adjacent power of different coolant flow channels
Spacing between battery is not identical, and entire cooling system runner is in U-shape.
Further, inlet and outlet is located at the two sides of battery, and direction is parallel, entire cooling system runner side view
Figure presents U-shaped.
Further, the spacing in power battery pack between each power battery forms the coolant flow channel, each cooling
Runner is in parallel relation.
Further, the spacing between the spacing of different coolant flow channels, that is, adjacent power battery is not identical: against air into
The spacing of the coolant flow channel of outlet is smaller than the spacing of the coolant flow channel of separate air ports.
The utility model is used for the U-shaped runner air cooling system of non-equidistant of power battery heat dissipation, air inlet and outlet
The two sides of battery are located at, and direction is identical, system runner side view presents U-shaped.
The utility model is used for the U-shaped runner air cooling system of non-equidistant of power battery pack heat dissipation, between coolant flow channel
Away from not identical: the runner spacing against air ports is minimum, and the runner spacing far from air ports is larger.
The utility model compared with prior art, has the advantage that
1. improving the air mass flow distribution between runner, guarantee the consistency of radiating condition between power battery, to subtract
The hot(test)-spot temperature and the temperature difference of low-power battery pack;
2. the design of non-equidistant runner changes point of pressure drop between runner compared with equidistant U-shaped runner cooling system
Match, but do not increase the overall presure drop between inlet and outlet substantially, because of the power consumption without increasing cooling system;
3. the design of non-equidistant runner changes the distribution of runner spacing compared with equidistant U-shaped runner cooling system, and
The size of entire cooling system is not increased.
