Background technology
With the continuous exhaustion of fossil energy and environmental protection and energy-saving and emission-reduction realize it is widely available, the energy it is reasonable
Efficiently utilize and obtain extensive concern.Electric automobile can reduce the consumption of fossil fuel, relatively using electrokinetic cell as driven by energy
Can be reduced to 20% on greenhouse gas emission in fuel-engined vehicle, therefore widely be paid close attention to and applied.Lithium from
Sub- battery pack is because its energy density is big, average output voltage is high, the low advantage of self-discharge rate is widely used in electric automobile field.
But, the close space structure of high current, battery pack and severe working environment during battery set charge/discharge are easily made
It is too high even with temperature distributing disproportionation into battery pack temperature rise, influence performance and the life-span of battery pack.Even when heat is accumulated to necessarily
Cells burst or blast can be triggered during degree.Therefore, it is the big of electric automobile safety traffic rationally to solve battery heat dissipation problem
Problem.
Although common air cooling simple structure, low cost, cooling velocity are slower, heat exchange coefficient is low, is put in high magnification
When electricity or environment temperature are higher, radiating effect is unable to reach requirement and battery temperature skewness.The conventional cold heat convection system of liquid
Number is larger, and the cooling velocity to battery pack is very fast, and battery temperature distribution is relatively more uniform, under identical circumstances, radiating effect
It is better than air cooling.But liquid is cold and forced air-cooling is required for extra heat dissipation equipment, such as fan, heat exchanger, increases energy
Consumption.
The content of the invention
For defect of the prior art, it is an object of the invention to provide one kind without extra heat dissipation equipment, can pass through
The electric automobile that electric automobile body is radiated to battery pack.
The present invention provides a kind of electric automobile, including battery pack and the heat abstractor for being radiated for the battery pack, institute
Vehicle body steel plate structure of the heat abstractor including metallic plate, heat pipe and electric motor car is stated, the metallic plate sets and connect with the battery pack
Touch and form heat transfer, the heat pipe includes heated parts and radiating part；
Heat transfer is formed with the battery pack in the heated parts insertion metallic plate, heated parts are connected simultaneously with the radiating part
By the heat heat transfer of the battery pack to the radiating part；
The radiating part and the vehicle body steel plate structure directly contact, and carry out heat transfer using the vehicle body steel plate structure
Radiating.
Electric automobile designed by the present invention, it is transmitted to battery pack the heat of water on the basis of conventional Water Cooling Technology
Vehicle body steel plate, i.e. water are passed to by battery pack, heat are taken out of, then by vehicle vehicle body, transfer heat to vehicle body steel plate,
Battery pack is finally returned, a circulation is formed.Because the thermal conductivity of steel plate is better than air, the coefficient of heat transfer is higher, and the system dissipates
Thermal effect is good, and due to the part using vehicle vehicle body steel plate structure as heat abstractor, it is not necessary to fan, heat exchanger, can be with
Reduce energy consumption.
