The heating system 14 may be provided as an air outlet device 141 and a heat exchange device 142. Wherein, the heat exchanging device 142 is connected with the air outlet device 141. After the air outlet device 141 is operated, air is delivered to the heat exchanging device 142, and the air absorbs at least part of heat on the heat exchanging device 142 and enters the cabin. Heat exchanging device 142 is at least partially coupled to power system 12 such that heat exchanging device 142 absorbs heat from power system 12. The powertrain 12 includes an engine 121. It is understood that the power system 12 may also be an electric motor or other device having a driving force. The heat exchanging device 142 is provided with a heat exchanging water passage, a first inlet port 142a and a first outlet port 142 b. The first liquid outlet 142b is disposed at one end of the heat-exchange water channel, and the first liquid inlet 142a is disposed at the other end of the heat-exchange water channel. The power system 12 is provided with a heat absorption water channel, a second liquid inlet and a second liquid outlet, wherein the second liquid outlet is arranged at one end of the heat absorption water channel, and the second liquid inlet is arranged at the other end of the heat absorption water channel. A first liquid inlet pipe 143 is disposed between the first liquid inlet 142a and the second liquid outlet, and a first liquid outlet pipe 144 is disposed between the first liquid outlet 142b and the second liquid inlet. One end of the first liquid inlet pipe 143 is connected to the first liquid inlet 142a, and the other end of the first liquid inlet pipe 143 is connected to the second liquid outlet. Correspondingly, one end of the first outlet pipe 144 is connected to the first outlet port 142b, and the other end of the first outlet pipe 144 is connected to the second inlet port. To this end, the first inlet pipe 143, the heat exchange water channel, the first outlet pipe 144 and the heat absorption water channel form a substantially closed circulation loop in which the cooling fluid is disposed.

When the heating system 14 is in operation, the cooling liquid enters the power system 12 from the second liquid inlet, and after absorbing heat of the power system 12, the cooling liquid leaves the power system 12 from the second liquid outlet of the power system 12. The cooling liquid outputted from the second liquid outlet at least partially reaches the first liquid inlet 142a through the first liquid inlet pipe 143 to enter the heat exchanging device 142. After the cooling fluid transfers heat to the air output by the blowing device 141 at the heat exchanging device 142, the cooling fluid leaves the heat exchanging device 142 from the first outlet port 142b of the heat exchanging device 142, and finally returns to the power system 12 through the first outlet port 144.

The valve 145 may be disposed on the first liquid inlet pipe 143, the first liquid outlet pipe 144, or both the first liquid inlet pipe 143 and the first liquid outlet pipe 144. In this embodiment, the valve 145 is disposed on the first inlet pipe 143. When the heating system 14 is in operation, at least a portion of the cooling fluid output from the second fluid outlet enters the heat exchanging device 142 through the two-way valve, so that the flow rate of the cooling fluid entering the heat exchanging device 142 is controlled through the two-way valve.

The return line 146 forms a flow path between the powertrain and the three-way valve that allows for the passage of coolant. When the heating system 14 is in operation, at least a portion of the coolant output from the second outlet of the power system 12 is discharged to the three-way valve, the coolant enters the three-way valve from the second inlet, and the coolant leaves the three-way valve from the second outlet or/and the third outlet. The coolant from the second output flows to the heat exchanger 142, and the coolant from the third output flows back to the power system 12 through the return line 146. The temperature of the heating system 14 is regulated by controlling the flow of coolant into the heat exchanger 142 and back to the power system 12 via a three-way valve.

Referring to fig. 9 and 11, as one implementation, fins 142k are provided between the heat-conducting members 142e, and fins 142k are provided between the heat-conducting members 142e and the shield 142 g. The fins 142k increase the heating area of the air, and improve the heating efficiency. The fins 142k are wavy. The length of the fin 142k is adapted to the length of the heat conductive member 142e, that is, the distance between the upper water chamber 142c and the lower water chamber 142d is a first distance, and the ratio of the length of the fin 142k to the first distance is greater than or equal to 0.9 and less than or equal to 1.

Referring to fig. 11, the cross section of the heat conduction member 142e may be rectangular, oval, diamond, or other shapes, which can be adjusted according to the actual situation. In the present embodiment, the cross sections of the heat-conducting member 142e and the second channel are both rectangular, and the wall thickness t of the heat-conducting member 142e in the circumferential direction is substantially equal. The length of the long side of the cross section of the heat conduction member 142e corresponds to the width W of the heat conduction member 142e, the length of the short side of the cross section of the heat conduction member 142e corresponds to the height B of the heat conduction member 142e, and the distance between two adjacent heat conduction members 142e is D. The larger the width of the heat-conducting member 142e is, the larger the heated surface of the air is, and the better the heating effect of the heating system 14 is; the larger the distance between the heat conduction members 142e is, the smaller the wind resistance is, and the larger the air volume of the heating system 14 is, but correspondingly, the smaller the number of the heat conduction members 142e is, the poorer the heating effect of the heating system 14 is; the smaller the wall thickness of the heat-conducting member 142e, the more efficiently the heat of the coolant is transferred to the outer wall of the heat-conducting member 142 e; the greater the height of the heat-conducting member 142e, the greater the wind resistance, and the smaller the air volume of the heating system 14. As one implementation, the ratio of the height B of the heat-conducting member 142e to the wall thickness t of the heat-conducting member 142e is greater than or equal to 3.8 and less than or equal to 8.2; the ratio of the width W of the heat-conducting member 142e to the wall thickness t of the heat-conducting member 142e is 76.9 or more and 136.4 or less; the ratio of the interval D of the heat-conducting members 142e to the wall thickness t of the heat-conducting members 142e is 13.8 or more and 18.2 or less. Through the arrangement, the heating system 14 has the advantages of large air volume and good heating effect. In the present embodiment, the wall thickness t of the heat-conducting member 142e is 0.22mm, and the flow rate is maximized as much as possible on the premise that the width W of the heat-conducting member 142e and the height B of the heat-conducting member 142e are constant.

In addition, a reinforcing area is formed between the branch pipes 147a, so that the strength of the foot blowing pipe 147 is increased, the stability of the foot blowing pipe 147 is improved, and the damage of the foot blowing pipe 147 is effectively prevented.
