[0039] The vehicle body cover 13 includes a front panel 131, which is disposed on the intermediate frame 111, and the air conditioner main unit 124 is located in front of the front panel 131. Figure 7 and Fig.14 As shown, the coaxial tube 123 is located between the evaporator 1241 and the condenser 122, and the coaxial tube 123 is located in front of the front panel 131, see Figure 7 and Figure 8 That is, the coaxial tube 123 is located between the front panel 131 and the condenser 122.

The radiator and the condenser 122 are arranged at intervals along the width direction of the frame 11, that is, the radiator is arranged at a position parallel to the condenser 122. Then, the coaxial tube 123 can also be located between the front panel 131 and the radiator. In the above arrangement, the condenser 122 does not affect the heat dissipation of the radiator, and the coaxial tube 123 is behind the condenser 122.

[0041] In this embodiment, if Fig. 9 As shown, the coaxial tube 123 includes an inner tube 1231 in an inverted U shape and an outer tube 1232 sleeved on the outer periphery of the inner tube 1231, and the outer tube 1232 is also in an inverted U shape. Fig.10 As shown, the inner cavity of the inner tube 1231 is the inner flow channel 102, and the outer flow channel 103 is formed between the inner tube 1231 and the outer tube 1232. That is, the inner part of the coaxial tube 123 defines the inner flow channel 102 and the outer flow channel 103 located outside the inner flow channel 102.

[0042] like Fig. 9 As shown, the outer tube 1232 includes a first vertical tube 1232a, a second vertical tube 1232b and a transverse tube 1232c. The first vertical tube 1232a and the second vertical tube 1232b are arranged at intervals along the width direction of the frame 11, and the first vertical tube 1232a and the second vertical tube 1232b both extend along the height direction of the frame 11. The transverse tube 1232c is located between the first vertical tube 1232a and the second vertical tube 1232b, and the transverse tube 1232c extends along the width direction of the frame 11. The lower portion of the second vertical tube 1232b is located below the lower portion of the first vertical tube 1232a.

[0043] like Figures 11 to 13 As shown, the first vertical tube 1232a is located on the left side of the second vertical tube 1232b. Fig.12 The front, rear, left, right, top and bottom are also defined in the figure. The transverse tube 1232c extends along the width direction of the frame 11, the left end of the transverse tube 1232c is connected to the upper end of the first vertical tube 1232a, and the right end of the transverse tube 1232c is connected to the upper end of the second vertical tube 1232b. In addition, according to the actual layout, the first vertical tube 1232a can also be located on the right side of the second vertical tube 1232b.

[0044] The first vertical tube 1232a and the second vertical tube 1232b are arranged at intervals along the width direction of the frame 11, so that the coaxial tube only occupies a space of one tube diameter in the length direction of the all-terrain vehicle, thereby reducing the space occupied in the length direction of the all-terrain vehicle, improving the compactness of the arrangement of the condenser and the evaporator, and better meeting the requirements of the compact structure of the all-terrain vehicle.

[0045] like Fig. 9 and Fig.10 As shown, the pipe section of the inner tube 1231 located in the first vertical tube 1232a is defined as the first pipe section 1231a, the pipe section of the inner tube 1231 located in the second vertical tube 1232b is defined as the second pipe section 1231b, and the pipe section of the inner tube 1231 located in the horizontal tube 1232c is the connecting pipe section, the left end of the connecting pipe section is connected to the first pipe section 1231a, and the right end of the connecting pipe section is connected to the second pipe section 1231b. Fig.12 and Fig.13 As shown, the coaxial tube 123 further includes a first connecting tube 1233, a second connecting tube 1234, a third tube section 1235, a fourth tube section 1236 and a fifth tube section 1237. The first connecting tube 1233 is arranged on the outer wall of the first vertical tube 1232a, and the first connecting tube 1233 is connected to the outer flow channel 103. The air conditioning system 12 further includes a connecting pipe 125, an expansion valve 126 and a pressure switch 127. The liquid outlet of the condenser 122 is connected to the first connecting pipe 1233 through the connecting pipe 125, and the pressure switch 127 is arranged on the connecting pipe 125.

[0046] The second connecting pipe 1234 is disposed on the outer wall of the second vertical pipe 1232b, and the second connecting pipe 1234 is connected to the outer flow channel 103. Along the fluid flow path between the condenser and the evaporator, the second connecting pipe 1234 is located downstream of the first connecting pipe 1233. Fig.13 and Fig.14 As shown, the evaporator 1241 has a refrigerant inlet and a refrigerant outlet. The second connecting pipe 1234 is connected to the refrigerant inlet of the evaporator 1241 through the expansion valve 126. In other words, the liquid outlet of the condenser 122 is connected to the refrigerant inlet of the evaporator 1241 through the connecting pipe 125, the first connecting pipe 1233, the outer flow channel 103 and the second connecting pipe 1234 in sequence.

[0047] like Fig.13 and Fig.14 As shown, the third pipe section 1235 bends and extends downward from the lower end of the first pipe section 1231a and toward the second pipe section 1231b. The fourth pipe section 1236 is formed by extending downward from the end of the third pipe section 1235, and the fourth pipe section 1236 is connected to the air intake of the compressor 121. In other words, the refrigerant outlet of the evaporator 1241 is connected to the air intake of the compressor 121 after passing through the inner flow channel 102, the third pipe section 1235 and the fourth pipe section 1236 in sequence.

[0048] The fifth pipe section 1237 is formed by extending downward from the lower end of the second pipe section 1231b, and the fifth pipe section 1237 is connected to the refrigerant outlet of the evaporator 1241, and the lower part of the fourth pipe section 1236 is located below the fifth pipe section 1237. In this way, the gas discharged from the refrigerant outlet of the evaporator passes through the fifth pipe section 1237, the inner flow channel 102, the third pipe section 1235 and the fourth pipe section 1236 in sequence and then communicates with the air intake of the compressor 121.

[0049] In order to reduce the space occupied by the entire coaxial tube in the width and length directions of the all-terrain vehicle, the above-mentioned first connecting tube 1233 is located in the space enclosed by the first vertical tube 1232a and the second vertical tube 1232b, and the second connecting tube 1234 is at least partially located between the fourth tube section 1236 and the fifth tube section 1237, and the second connecting tube 1234 is located below the first connecting tube 1233.

[0050] In order to facilitate the installation of the second connecting pipe 1234 and the second pipe section 1231b, the second connecting pipe 1234 and the second pipe section 1231b are installed on the expansion valve 126 through a first mounting plate.

[0051] The presence of the coaxial tube 123 shortens the refrigeration pipeline and reduces the space occupied by the refrigeration pipeline in front of the passenger cabin 101, thereby better meeting the requirements of the all-terrain vehicle having a compact structure and limited space.

[0052] The refrigeration principle of the air conditioning system 12 is as follows: the evaporator 1241 of the air conditioning main unit 124 is filled with refrigerant, and the compressor 121 compresses the refrigerant into high-temperature and high-pressure gas. The high-temperature and high-pressure gas dissipates heat through the condenser 122 and becomes high-pressure liquid. After the high-pressure liquid passes through the outer flow channel 103 of the coaxial tube 123, it is throttled by the expansion valve 126 and becomes low-pressure liquid. The low-pressure liquid absorbs the heat in the air conditioning main unit 124 after passing through the evaporator 1241, and the temperature in the air conditioning main unit 124 decreases. The cold air in the air conditioning main unit 124 is discharged into the passenger cabin 101 to cool down the passenger cabin 101. After passing through the evaporator 1241, the low-pressure liquid becomes low-temperature and low-pressure gas. The low-temperature and low-pressure gas enters the compressor 121 again after passing through the inner flow channel 102 of the coaxial tube 123, forming a cycle, and realizing continuous blowing of cold air to the passenger cabin 101.

[0053] like Fig.14As shown, the power system 14 includes an engine 141. The air conditioning system 12 also includes a warm air duct 128, and the warm air duct 128 includes a first warm air duct 1281 and a second warm air duct 1282. The first warm air duct 1281 is connected to a first end of the heater 1242, and a second end of the heater 1242 is connected to the engine 141 through the second warm air duct 1282. The coolant enters the heater 1242 through the first warm air duct 1281, and the blower 1243 blows air through the heater 1242, so that the heater 1242 heats the air, and the heated air is finally transported to the passenger cabin 101, realizing the heating function of the all-terrain vehicle 100.
