Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0088] According to a first aspect of the present application, a heating system is provided, Figure 1 It can be seen that the heating system includes:

[0089] Power unit 2;

[0093] The heating passage 4 is connected to the cooling passage 1 used to dissipate heat from the power unit 2. The heating passage 4 and the cooling passage 1 share the same heat exchange medium, so that the heat exchange medium can pass through the cooling passage 1 to exchange heat with the radiator 3 and the power unit 2, and can also flow into the heating passage 4 to provide heat to the drivers and passengers, which not only improves the thermal comfort of the drivers and passengers, but also saves more energy.

[0094] Exemplarily, the power device 2 may be any one or more of a motor, an engine, a battery, a car charger, a power distribution unit, and the like.

[0095] The heat exchange medium is the vehicle's coolant, and the specific type can be selected according to needs.

[0096] In some embodiments, the heating system further comprises:

[0097] A first input section 5, one end of the cooling passage 1 and one end of the heating passage 4 are both connected to one end of the first input section 5, and the other end of the first input section 5 is connected to the power device 2 for heat exchange, for inputting a heat exchange medium for heat exchange with the power device 2; and,

[0098] The first output section 6, the other end of the cooling passage 1 and the other end of the heating passage 4 are all connected to one end of the first output section 6, and the other end of the first output section 6 is connected to the power device 2 for heat exchange, and is used to output the heat exchange medium after heat exchange with the power device 2.

[0099] After the heat exchange medium exchanges heat with the power unit 2, it can be input from the first output section 6 to the heating passage 4 to provide heating for the driver and passengers, and then flow back from the heating passage 4 to the first input section 5 to complete the heating cycle; it can also be input from the first output section 6 to the cooling passage 1 to exchange heat with the radiator 3, and then flow back from the cooling passage 1 to the first input section 5 to complete the cooling cycle.

[0100] Specifically, one end of the cooling passage 1, one end of the heating passage 4, and one end of the first input section 5 are connected through the first three-way valve 12; the other end of the cooling passage 1, the other end of the heating passage 4, and the first output section 6 are connected through the second three-way valve 13.

[0101] In some embodiments, the heating passage 4 includes:

[0102] Two first branches 41, one end of one first branch 41 is connected to the first output section 6, one end of the other first branch 41 is connected to the first input section 5, and the other end of one first branch 41 is connected to the other end of the other first branch 41; and,

[0103] One or more second branches 42 , the second branches 42 can provide heat to the lower limbs of the driver and passenger, and the other end of a first branch 41 and the other end of another first branch 41 are both connected to the second branch 42 .

[0104] The heat exchange medium can flow into a first branch 41 through the first output section 6, and then flow into the second branch 42 to exchange heat with the heating passage 4, and then flow into the first input section 5 through another first branch 41 to complete the heating cycle.

[0105] In some embodiments, the heating passage 4 further includes a water divider 43 , and the other end of a first branch 41 , the other end of another first branch 41 , and the second branch 42 are all connected to the water divider 43 .

[0106] The heat exchange medium may flow through a first branch 41 , a second branch 42 and another first branch 41 in sequence through the water distributor.

[0107] In some embodiments, combined Figure 1-2 It can be seen that when there are multiple second branches 42, the multiple second branches 42 are respectively used for different seats 7 of the vehicle and are respectively used to heat the lower limbs of the drivers and passengers in different seats 7.

[0108] For example, multiple second branches 42 may be respectively used for the left front seat 7, the right front seat 7, the left rear seat 7, and the right rear seat 7 of the vehicle. When there is no occupant in seat 7, the second branch 42 may be automatically closed to avoid wasting heat. When there is no occupant in seat 7, the second branch 42 may be manually selected to remain open, so that the second branch 42 continues heating.

[0109] In some embodiments, at least one first branch 41 is provided with a first switch 411, which can control the on / off state of the first branch 41. The first switch 411 can control the on / off state of the first branch 41, thereby controlling whether the waste heat of the power device 2 is used to heat the heating passage 4.

[0110] In some embodiments, at least one first branch 41 is provided with a heater 412 , and the heater 412 is used to heat the heat exchange medium of the first branch 41 .

[0111] The heat exchange medium flowing through the first branch 41 can be heated by the heater 412 so as to ensure the heating effect when the residual heat of the power device 2 is insufficient.

[0112] Specifically, the heater 412 is located on the first branch 41 for the heat exchange medium to flow into the second branch 42 .

[0113] In some embodiments, a third switch 421 is provided at at least one second branch 42, which can control the on and off of the second branch 42, so that the corresponding heating passage 4 can independently control whether to supply heat.

[0114] In some embodiments, a third switch 421 is provided at each of the plurality of second branches 42 .

[0115] In some embodiments, at least one second branch 42 is provided with a first temperature sensor 422 , which can detect the heating temperature of the second branch 42 to more accurately confirm the heating temperature of the heating passage 4 .

[0116] In some embodiments, each of the plurality of second branches 42 is provided with a first temperature sensor 422 .

[0117] In some embodiments, the cooling passage 1 is provided with a fourth switch 11 , which can control the on / off of the cooling passage 1 , so as to disconnect the cooling passage 1 when the radiator 3 is not needed for heat dissipation.

[0118] In some embodiments, a second temperature sensor 51 is provided at the first output section 6 and / or the first input section 5. The second temperature sensor 51 can collect the temperature of the heat exchange medium in the first output section 6 and / or the first input section 5, can collect the temperature of the heat exchange medium flowing out of and / or flowing into the power device 2, and can control the heat dissipation strategy of the cooling passage 1 and / or the radiator 3 for the power device 2 based on the obtained temperature of the heat exchange medium.

[0119] In some embodiments, a pump body 61 is provided at the first output section 6 , and the pump body 61 can drive the heat exchange medium in the first output section 6 to flow; and / or,

[0120] A pump body 61 is provided at the first input section 5 , and the pump body 61 can drive the heat exchange medium in the first input section 5 to flow.

[0121] When the pump body 61 is working, it can drive the heat exchange medium to perform a heating cycle, and / or it can drive the heat exchange medium to perform a cooling cycle.

[0122] In some embodiments, the second branch 42 includes:

[0123] The second input section 423, the other end of the first branch 41 is connected to one end of the second input section 423;

[0124] A second output section 424, one end of which is connected to the other end of the other first branch 41; and

[0125] The heating plate 425 , the other end of the second input section 423 and the other end of the second output section 424 are all connected to the heating plate 425 , so that the heating plate 425 can provide heat to the feet of the driver and passengers.

[0126] The heat exchange medium is input to the heating plate 425 through the second input section 423. After the heat exchange medium exchanges heat with the heating plate 425, the feet of the driver and passengers can be heated through the heating plate 425, which can effectively improve the thermal comfort of the driver and passengers. After passing through the heating plate 425, the heat exchange medium can be output through the second output section 424.

[0127] In some embodiments, combined Figure 3 、 4 It can be seen that a heating channel 426 is provided in the heating plate 425. The heating plate 425 also has an input port 427 and an output port 428. The heating passage 4 is connected to the heating channel 426 through the input port 427 and the output port 428.

[0128] The heat exchange medium can be input from the heating passage 4 to the heating channel 426 through the input port 427 , and can be discharged from the heating channel 426 to the heating passage 4 through the output port 428 .

[0129] The heat exchange medium directly flows in the heating plate 425 , which can effectively improve the heat exchange efficiency between the heat exchange medium and the heating plate 425 .

[0130] In some embodiments, the input port 427 and the output port 428 are located on the same side of the heating plate 425 to facilitate the connection between the heating plate 425 and the second branch 42. Specifically, the input port 427 and the output port 428 can be set at the upper and lower positions on the same side, or at the left and right positions on the same side.

[0131] In some embodiments, combined Figure 4 It can be seen that the heating channel 426 includes:

[0132] A first flow channel 4261, which is connected to the input port 427; and

[0133] The second flow channel 4262 has two ends connected to the first flow channel 4261 and the output port 428 respectively;

[0134] The first flow channel 4261 and the second flow channel 4262 are alternately arranged in the heating plate 425 .

[0135] The first flow channel 4261 is the channel for the heat exchange medium to flow in, and the second flow channel 4262 is the channel for the heat exchange medium to flow out. Since the temperature of the heat exchange medium when it flows in is higher than the temperature when it flows out, the first flow channel 4261 and the second flow channel 4262 are staggered, which can make the temperature of the heating plate 425 after heat exchange with the heat exchange medium more uniform.

[0136] In some embodiments, the heating plate 425 includes:

[0137] The main body 4251 is heat-insulated and has a heating groove;

[0138] The heat dissipation portion 4252 is used to support the feet of the driver and passenger. The heat dissipation portion 4252 is covered on the heating groove of the main body 4251 , and the heat dissipation portion 4252 and the heating groove of the main body 4251 together form a heating flow channel 426 .

[0139] The heat-insulating main body 4251 can prevent heat energy from dissipating, and the heat dissipation portion 4252 is in direct contact with the heating tank, so that the heat exchange medium flowing through the heating tank can transfer heat energy to the heat dissipation portion 4252 more concentratedly and efficiently.

[0140] For example, the main body 4251 is made of a heat-insulating material with good performance, such as a closed-cell foam metal material, and the heat dissipation portion 4252 is made of a metal material with good thermal conductivity.

[0141] In some embodiments, heat dissipation fins 4253 are provided on the heat dissipation portion 4252 , and the heat dissipation fins 4253 can improve the heating efficiency of the driver's and passenger's feet.

[0142] Illustratively, the first switch 411 to the fourth switch 11 may be solenoid valves, or other switch structures for controlling the on / off of a passage.

[0143] In some embodiments, in combination Figure 5 It can be seen that this embodiment is Figure 1 Compared with the embodiment shown, the difference is that the heating passage 4 also includes:

[0144] The third branch 44, both ends of the third branch 44 are connected to the first branch 41; and,

[0145] The heat accumulator 45 can store or release thermal energy. The heat accumulator 45 is connected to the third branch 44 for heat exchange. The heat exchange medium in the first branch 41 can flow through the third branch 44 to exchange heat with the heat accumulator 45.

[0146] When the heat exchange medium flows through the heating passage 4 and enters the third branch 44, and the residual heat is still sufficient, the heat accumulator 45 can exchange heat with the heat exchange medium to store thermal energy; when the residual heat of the power unit 2 is insufficient, the heat accumulator 45 can exchange heat with the heat exchange medium to release thermal energy.

[0147] In some embodiments, the heating passage 4 further includes a second switch 46, which is disposed on the third branch 44 and can control the on / off state of the third branch 44. The second switch 46 is used to control whether the heat exchange medium flows through the heat accumulator 45, thereby controlling the storage or release of heat energy in the heat accumulator 45.

[0148] According to a second aspect of the present application, a thermal management system is provided, comprising the heating system of the first aspect.

[0149] In some embodiments, combined Figure 6 It can be seen that the thermal management system also includes an air intake grille 8, which is used to be installed on the vehicle. The air intake grille 8 has an air intake, which can circulate air to the radiator 3 to dissipate heat for the radiator 3, and can more effectively increase the heat dissipation effect of the radiator 3.

[0150] In some embodiments, the air intake grille 8 can control the opening degree of the air intake, making the adjustment of the thermal management system more flexible and convenient.

[0151] According to a third aspect of the present application, a vehicle is further provided, comprising the heating system of the first aspect or the thermal management system of the second aspect.

[0152] In some embodiments, the heating plate 425 of the heating passage 4 is detachably installed at the seat 7 and can be replaced with a metal base plate as needed, so that the heating passage 4 can be optionally installed as needed.

[0153] According to the fourth aspect of the present application, a method is also provided, combining Figure 7 It can be seen that the method is applied to the heating system of the first aspect, or to the thermal management system of the second aspect, or to the vehicle of the third aspect, and the method includes:

[0157] When the driver and passengers need heating, a heating instruction is issued to control the heat exchange between the power unit 2 and the heating passage 4, so that the heat energy of the power unit 2 can be transported to the heating passage 4 to heat the lower limbs of the driver and passengers, thereby improving the thermal comfort of the driver and passengers and saving energy.

[0158] In some embodiments, controlling the heat exchange between the power device 2 and the heating passage 4 according to the heating instruction includes:

[0159] Obtain the temperature of the heating passage 4 and the heating temperature according to the heating instruction;

[0160] When the temperature of the second branch 42 is lower than the heating temperature, the flow of the heat exchange medium in the heating passage 4 is controlled to allow the power device 2 and the heating passage 4 to exchange heat, and then through the heat exchange between the power device 2 and the heating passage 4, the heating passage 4 reaches the required heating temperature.

[0161] In some embodiments, after controlling the flow of the heat exchange medium in the heating passage 4 so that the power device 2 and the heating passage 4 exchange heat, the method further includes:

[0162] When the temperature of the second branch 42 is lower than the heating temperature, the heater 412 is controlled to heat the heat exchange medium flowing to the second branch 42 to ensure that the temperature of the heating plate 425 of the second branch 42 can be raised to the required temperature.

[0163] In some embodiments, after controlling the heater 412 to heat the heat exchange medium flowing to the second branch 42, the method further includes:

[0164] When the temperature of the second branch 42 is lower than the heating temperature, the power device 2 is controlled to generate heat inefficiently.

[0165] When the temperature of the second branch 42 is not enough and the heating of the heater 412 cannot meet the heating temperature required by the heating plate 425, the power device 2 can further generate heat inefficiently to increase the heat energy transferred from the power device 2 to the heat exchange medium.

[0166] In some embodiments, after controlling the heat exchange between the power device 2 and the heating passage 4 according to the heating instruction, the method further includes:

[0167] Obtaining the temperature of the heat exchange medium in the first input section 5;

[0168] A heat dissipation strategy is determined according to the temperature of the heat exchange medium in the first input section 5 , and at least one of the cooling passage 1 and the radiator 3 is controlled according to the heat dissipation strategy.

[0169] The heat dissipation strategy is determined based on the temperature of the heat exchange medium in the first input section 5 after supplying heat to the heating passage 4, so that when the heat exchange medium circulates, it can meet both the heating requirements of the heating passage 4 and the heat dissipation requirements of the power device 2.

[0170] In some embodiments, determining a heat dissipation strategy based on the temperature of the heat exchange medium in the first input section 5 and controlling at least one of the cooling passage 1 and the radiator 3 based on the heat dissipation strategy includes:

[0171] When the temperature of the heat exchange medium in the first input section 5 is greater than a first threshold, the flow rate or flow of the heat exchange medium in the cooling passage 1 is controlled.

[0172] Specifically, when the temperature of the heat exchange medium is greater than the second threshold, all the fourth switches 11 in the cooling passage 1 are controlled to be opened.

[0173] In some embodiments, after controlling the flow rate or flow rate of the heat exchange medium in the cooling passage 1, the method further includes:

[0174] When the temperature of the heat exchange medium in the first input section 5 is greater than the second threshold, the opening degree of the air intake grille 8 is controlled;

[0175] The first threshold is smaller than the second threshold.

[0176] When the temperature of the heat exchange medium after supplying heat to the heating passage 4 reaches a second threshold, the excess heat energy can be released to the external environment through the cooperation of the radiator 3 and the air intake grille 8 .

[0177] In some embodiments, when the temperature of the heat exchange medium is greater than the first threshold, the heat dissipation strategy may also be to control the flow rate or flow of the heat exchange medium in the cooling passage 1 , or to control the opening degree of the air intake grille 8 .

[0178] Specifically, the flow rate or flow of the heat exchange medium in the cooling passage 1 is controlled by the opening degree of the fourth switch 11. In the interval where the temperature of the heat exchange medium is greater than the first threshold and less than the second threshold, the opening degree of the fourth switch 11 can be mapped to the temperature of the heat exchange medium between the first threshold and the second threshold, and can be linearly adjusted as the temperature of the heat exchange medium changes between the first threshold and the second threshold to achieve control of the flow rate or flow of the heat exchange medium in the cooling passage 1. In the interval where the temperature of the heat exchange medium is greater than the first threshold and less than the second threshold, the opening degree of the air intake grille 8 is half open; when the temperature of the heat exchange medium is greater than the second threshold, the fourth switch 11 or the air intake grille 8 is fully opened.

[0180] Get heating instructions;

[0181] According to the heating instruction, the number and position of the seats 7 requiring heating, the temperature of the heating passage 4 at each seat 7 requiring heating, and the required heating temperature are obtained, and the following operations are performed on the heating system or thermal management system at each seat 7 requiring heating:

[0182] When the temperature of the second branch 42 is lower than the heating temperature, the flow of the heat exchange medium in the heating passage 4 is controlled to allow the power device 2 and the heating passage 4 to exchange heat;

[0183] When the temperature of the second branch 42 is lower than the heating temperature, the heater 412 is controlled to heat the heat exchange medium flowing into the second branch 42 to ensure that the temperature of the heating plate 425 of the second branch 42 can be raised to the required temperature; when the temperature of the second branch 42 is still lower than the heating temperature, the heater 412 is controlled to heat the heat exchange medium flowing into the second branch 42; when the temperature of the second branch 42 is still lower than the heating temperature, the power device 2 is controlled to generate heat inefficiently;

[0184] After controlling the heat exchange between the power unit 2 and the heating passage 4 according to the heating instruction, the temperature of the heat exchange medium in the first input section 5 is obtained. A heat dissipation strategy is determined based on the temperature of the heat exchange medium in the first input section 5, and at least one of the cooling passage 1 and the radiator 3 is controlled based on the heat dissipation strategy.
