An all-terrain vehicle 100 according to an embodiment of the invention is described below with reference to fig. 1-4.

As shown in fig. 1, an all-terrain vehicle 100 according to an embodiment of the present invention includes: frame 10, driver's cabin 20, power unit 30, first radiator 40 and second radiator 41, wherein, driver's cabin 20 sets up on frame 10, can guarantee driver's cabin 20 and can guarantee the stability of all-terrain vehicle 100 installation setting, and driver's cabin 20 can supply driver and passenger to take to can make driver control all-terrain vehicle 100, can promote the user to all-terrain vehicle 100's use experience.

Further, as shown in fig. 1 to 3, the power unit 30 is provided to the vehicle frame 10, the cooling duct 31 is provided in the power unit 30, the first radiator 40 is provided to the vehicle frame 10 and located in front of the cab 20, the first radiator 40 is in communication with the cooling duct 31, the second radiator 41 is provided to the vehicle frame 10 and located behind the cab 20, and the second radiator 41 is in communication with the cooling duct 31. Specifically, by disposing the power unit 30, the first radiator 40 and the second radiator 41 on the frame 10, the stability and the firmness of the installation of the power unit 30, the first radiator 40 and the second radiator 41 on the atv 100 can be ensured. In addition, by arranging the first radiator 40 and the second radiator 41 in front of and behind the cab 20, respectively, on the premise of ensuring stable and firm arrangement of the first radiator 40 and the second radiator 41, the first radiator 40 and the second radiator 41 can make full use of available space on the all-terrain vehicle 100, the space utilization rate of the all-terrain vehicle 100 can be improved, and the structure of the all-terrain vehicle 100 can be made more compact.

Further, referring to fig. 4, both the first radiator 40 and the second radiator 41 are communicated with the cooling channel 31 of the power unit 30, wherein the cooling channel 31 is a two-way channel, when the power unit 30 drives the atv 100 to normally run, the temperature inside the power unit 30 rises, the liquid medium 32 in the power unit 30 absorbs the heat of the power unit 30 to reduce the temperature of the power unit 30, and after the temperature of the power unit 30 is maintained in a reasonable area, the liquid medium 32 can enter the first radiator 40 and the second radiator 41 through the cooling channel 31, the first radiator 40 and the second radiator 41 can exchange heat between the heat in the liquid medium 32 and the surrounding air, so that the surrounding air takes away the heat in the liquid medium 32 to reduce the temperature of the liquid medium 32, and the temperature of the liquid medium 32 is reduced to a reasonable area, the liquid medium 32 with normal temperature enters the power unit 30 through the cooling channel 31 to dissipate heat and cool the power unit 30, so that the first radiator 40 and the second radiator 41 can realize a cooling circulation loop for cooling the power unit 30.

Thus, by arranging the first radiator 40 and the second radiator 41 on the all-terrain vehicle 100, compared with the all-terrain vehicle only provided with the first radiator 40 on the front side of the vehicle body, when the power unit 30 works at high power, the heat generation amount of the power unit 30 is large, and the heat dissipation effect of the first radiator 40 on the power unit 30 is insufficient, the heat dissipation effect on the power unit 30 can be increased by the additionally arranged second radiator 41, so that the power unit 30 can be ensured to work continuously and stably, and the reliability of the all-terrain vehicle 100 can be further improved.

In addition, the first radiator 40 may be a main radiator, the second radiator 41 may be an auxiliary radiator, and when the power unit 30 has normal power and the heat dissipation effect of the first radiator 40 on the power unit 30 is sufficient, the second radiator 41 may be in a shutdown state, so that unnecessary waste caused by the operation of the second radiator 41 can be avoided on the premise that the temperature of the power unit 30 is in a reasonable region and the power unit 30 can normally operate, which not only can prolong the service life of the second radiator 41, but also can reduce the energy consumption of the all-terrain vehicle 100.

Of course, at the time of cold start of the power unit 30, the liquid medium 32 in the cooling passage 31 may not pass through the first radiator 40 and the second radiator 41, but may quickly flow back into the cooling passage 31, so that the temperature of the power unit 30 may be quickly increased to be within a reasonable range.

Therefore, by arranging the first radiator 40 in front of the cab 20, arranging the second radiator 41 behind the cab 20, and communicating both the first radiator 40 and the second radiator 41 with the cooling channel 31, not only the arrangement layout of the first radiator 40 and the second radiator 41 can be more reasonable, the structure of the all-terrain vehicle 100 can be more compact, but also the heat dissipation effect of the all-terrain vehicle 100 on the power unit 30 can be improved, and the reliability of the all-terrain vehicle 100 can be further improved.

Alternatively, as shown in fig. 4, the first radiator 40, the second radiator 41 and the cooling channel 31 are connected in series, so that the high-temperature liquid medium 32 in the power unit 30 can enter the first radiator 40 from the cooling channel 31 to perform heat dissipation and cooling, and then enter the second radiator 41 to perform secondary cooling, which can make the heat dissipation and cooling effects of the first radiator 40 and the second radiator 41 on the liquid medium 32 better, so as to improve the heat dissipation and cooling effects of the first radiator 40 and the second radiator 41 on the power unit 30, it should be explained that when the heat dissipation effect of the first radiator 40 is sufficient, and the second radiator 41 is in the shutdown state, the liquid medium 32 can still circulate from the second radiator 41 instead of being blocked at the second radiator 41, but at this time, the second radiator 41 does not perform heat dissipation on the liquid medium 32. In addition, due to the arrangement, the number of required pipelines is small, the installation cost can be reduced, and the installation space can be saved.

Alternatively, the first radiator 40 and the second radiator 41 are connected in parallel and are both connected in series with the cooling channel 31, so that the liquid medium 32 in the power unit 30 can enter the first radiator 40 and the second radiator 41 from the cooling channel 31 at the same time, the flow rate of the liquid medium 32 entering the first radiator 40 and the second radiator 41 per unit time can be increased, and the heat dissipation and temperature reduction effects of the first radiator 40 and the second radiator 41 on the power unit 30 can also be improved.

Specifically, the liquid medium 32 in the power unit 30 may flow from the water outlet of the cooling channel 31 to the third pipeline 44 connected thereto, and flow from the third pipeline 44 to the water inlet of the first radiator 40, after the first radiator 40 performs the heat dissipation and temperature reduction treatment on the liquid medium 32, the liquid medium 32 may flow out from the water outlet of the first radiator 40, enter the first pipeline 42, then enter the water inlet of the second radiator 41 through the first pipeline 42, and flow into the second radiator 41 from the water inlet of the second radiator 41, after the liquid medium 32 is subjected to the secondary heat dissipation treatment by the second radiator 41, and the temperature of the liquid medium 32 is reduced to a reasonable region by heat dissipation, the liquid medium 32 may flow into the second pipeline 43 from the water outlet of the second radiator 41, and flow into the cooling channel 31 again through the second pipeline 43, flow into the power unit 30 again from the cooling channel 31, and then recirculates back and forth so that a cooling circulation circuit of the first radiator 40 and the second radiator 41 to the power unit 30 can be formed.

This not only ensures the reliability of the cooling cycle of the power unit 30 by the first radiator 40 and the second radiator 41, but also makes the pipe through which the liquid medium 32 flows simple and direct, increases the speed of the cooling cycle, and prevents the liquid medium 32 from stagnating and sticking in the pipe. In addition, the cooling circulation loop can be further provided with a water pump, the water pump can provide power for circulation of the liquid medium 32, the water pump can be in transmission connection with the power unit 30, namely the power unit 30 can drive the water pump to work simultaneously when working, and therefore the liquid medium 32 can be guaranteed to participate in heat exchange work when the power unit 30 just starts to work.

Specifically, the first fan and the second fan can accelerate the flow rate of air around the first radiator 40 and the second radiator 41, respectively, so that the heat exchange speed between the air around the first radiator 40 and the second radiator 41 and the liquid medium 32 in the first radiator 40 and the second radiator 41 can be increased, the air around the first radiator 40 and the second radiator 41 can be enabled to take away heat in the liquid medium 32 more quickly, and the heat dissipation efficiency of the first radiator 40 and the second radiator 41 can be improved.

Further, the working states of the first fan and the second fan are accurately controlled by the controller, when the power unit 30 has normal power and the heat dissipation effect of the first heat sink 40 on the power unit 30 is sufficient, the controller can control the first fan to continuously work and control the second fan to stop working, so that unnecessary waste caused by rotation of the second fan can be avoided on the premise that the temperature of the power unit 30 is in a reasonable area and the power unit 30 can normally work, the service life of the second fan can be prolonged, and the energy consumption of the all-terrain vehicle 100 can be reduced.
