Electric vehicle
View Patent ↗A liquid leakage countermeasure of a cooling medium channel is facilitated, and a need of high power of a pump for circulating a cooling medium is relaxed. An electric vehicle includes: a vehicle body including a dashboard which separates a front space covered with a hood and a boarding space provided with a seat on which a driver is seated; an electric component which is provided behind the dashboard and generates heat by electric energy for generating rotational power for vehicle traveling; and a heat exchanger provided behind the dashboard and configured to cool down a cooling medium circulating between the heat exchanger and the electric component.
1. An electric vehicle comprising:
a vehicle body including a dashboard which separates a front space covered with a hood and a boarding space provided with a seat on which a driver is seated;
an electric component which is provided behind the dashboard and generates heat by electric energy for generating rotational power for vehicle traveling, the electric component including a motor unit; and
a radiator provided behind the dashboard and configured to cool down a cooling medium circulating between the radiator and the electric component, wherein:
the vehicle body includes a vehicle body exposed surface facing an outer space;
the radiator is arranged outside the vehicle body exposed surface; and
the radiator is fixed to not the vehicle body but the motor unit.
2. The electric vehicle according to claim 1 , wherein:
the radiator radiates the heat of the cooling medium to outside air which contacts and flows through the radiator; and
the radiator is arranged outside the vehicle body exposed surface so as to extend in a direction along the vehicle body exposed surface or a direction intersecting with the vehicle body exposed surface.
3. The electric vehicle according to claim 1 , wherein:
the radiator radiates the heat of the cooling medium to outside air which contacts and flows through the radiator;
the radiator is arranged so as to intersect with a forward and rearward direction of the electric vehicle; and
the radiator is provided at such a position that at least a part thereof is visible when viewed from a vehicle rear side.
4. The electric vehicle according to claim 1 , wherein the radiator is arranged behind axles of rear wheels and under and in front of a rear end of the vehicle body.
5. The electric vehicle according to claim 1 , further comprising a cargo bed provided at the vehicle body so as to be arranged behind the boarding space, wherein:
the radiator and the electric component are arranged under the cargo bed.
6. The electric vehicle according to claim 1 , wherein the electric component includes at least an inverter.
7. The electric vehicle according to claim 1 , further comprising a cargo bed provided in the vehicle body so as to be arranged behind the boarding space, wherein:
the radiator is arranged under the cargo bed;
the radiator radiates the heat of the cooling medium to outside air which contacts and flows through the radiator; and
a heat exchange surface of the radiator is arranged so as to intersect with a forward and rearward direction of the electric vehicle.
8. The electric vehicle according to claim 1 , wherein:
the vehicle body includes a metal frame having the vehicle body exposed surface; and
the radiator is a metal tubular member contacting the vehicle body exposed surface of the frame.
9. The electric vehicle according to claim 8 , wherein:
the electric component includes an inverter; and
the tubular member connects the motor unit to the inverter.
10. An electric vehicle, comprising:
a vehicle body including a dashboard which separates a front space covered with a hood and a boarding space provided with a seat on which a driver is seated;
an electric component which is provided behind the dashboard and generates heat by electric energy for generating rotation power for vehicle traveling;
a radiator provided behind the dashboard and configured to cool down a cooling medium circulating between the radiator and the electric component; and
a cargo bed provided at the vehicle body so as to be arranged behind the boarding space; wherein:
the vehicle body includes a vehicle body exposed surface facing an outer space;
the radiator is arranged outside the vehicle body exposed surface, behind the boarding space and under the cargo bed;
a lower end of the radiator is located above a bottom surface of the vehicle body; and
an entire back surface of the radiator is visible when viewed from a vehicle rear side.
11. The electric vehicle according to claim 10 , wherein:
the radiator is arranged under the cargo bed.
12. The electric vehicle according to claim 11 , wherein:
the radiator is arranged behind axles of rear wheels and under and in front of a rear end of the vehicle body.
13. The electric vehicle according to claim 10 , wherein:
a heat exchange surface of the radiator is arranged so as to extend in a direction intersecting with a vertical direction.
14. The electric vehicle according to claim 10 , wherein:
the electric component includes an inverter;
the inverter is arranged at one side of a center of the vehicle body in a vehicle width direction; and
the radiator is also arranged at the one side of the center of the vehicle body in the vehicle width direction.
15. The electric vehicle according to claim 10 , wherein:
the radiator is arranged behind axles of rear wheels; and
the radiator is provided in such a rearward inclined posture that an upper end portion of the radiator is located at a rear side of a lower end portion of the radiator.
16. The electric vehicle according to claim 10 , wherein the cargo bed is capable of banking so as to incline rearward.
