Description

Air conditioning systems and vehicles Technical Field

[0001] This application relates to the field of vehicle technology, specifically to an air conditioning system and a vehicle. Background Technology

[0002] Currently, vehicles use traditional ducted air supply to cool or heat the passenger compartment to regulate the interior temperature. The working principle of ducted air supply is as follows: the cold air core or warm air core in the air conditioning unit drives the air inside the vehicle to exchange heat with the refrigerant or coolant of the air conditioning system through a fan, delivering cold or hot air to the head and foot areas of the front passenger compartment, etc., and then through longer ducts to deliver the air to the rear passenger compartment.

[0003] However, the ducted air supply method has a slow temperature response, and the rear seats are prone to not cooling or heating, resulting in poor temperature regulation. Summary of the Invention

[0004] This application provides an air conditioning system and vehicle that can improve temperature regulation.

[0005] In a first aspect, embodiments of this application provide an air conditioning system, which may include:

[0006] The first heat exchange module, water pump, pipeline and N second heat exchange modules form a first loop, where N is an integer greater than or equal to 1;

[0007] Among them, N second heat exchange modules are installed in the vehicle's cabin;

[0008] A water pump is used to drive the first fluid in the first circuit to flow in the first circuit; a first heat exchange module is used to passively exchange heat between the first fluid flowing through the first heat exchange module and the second fluid flowing through the first heat exchange module; a second heat exchange module is used to actively exchange heat between the first fluid flowing through the second heat exchange module and the air in the cabin.

[0009] The first heat exchange module enables passive heat exchange between the first and second fluids. Passive heat exchange requires no external energy input and achieves heat exchange through natural convection and heat conduction. Passive heat exchange allows heat to be transferred from a higher-temperature object to a lower-temperature object. For example, when the air conditioning system is operating in cooling mode, the temperature of the first fluid is higher than that of the second fluid, and the first fluid transfers heat to the second fluid; conversely, when the air conditioning system is operating in heating mode, the temperature of the first fluid is lower than that of the second fluid, and the second fluid transfers heat to the first fluid.

[0010] The first fluid can be a liquid or a gas. It can be water or a coolant (e.g., a mixture of water and ethanol) or a gas (e.g., air). The coolant can be a liquid that meets the characteristics of non-freezing, non-corrosiveness, low viscosity, and high specific heat. The second fluid can be a liquid (e.g., water, antifreeze, refrigerant, etc.) or a gas (e.g., air, vaporized refrigerant, etc.). The pipeline can include liquid pipelines or gas pipelines. Liquid or gas flow is permitted within the pipeline. When liquid flow is permitted, the pipeline can be a liquid pipeline (e.g., a water pipe); when gas flow is permitted, the pipeline can be a gas pipeline.

[0011] In one possible embodiment, the first heat exchange module may be a condenser or an evaporator. For example, the first heat exchange module may be a condenser or evaporator in the vehicle's air conditioning unit. When the air conditioning system operates in cooling mode, the second fluid in the second circuit absorbs heat in the evaporator, and the first fluid in the first circuit dissipates heat in the evaporator. When the air conditioning system operates in heating mode, the second fluid in the second circuit dissipates heat in the condenser, and the first fluid in the first circuit absorbs heat in the condenser.

[0012] In another possible embodiment, the first heat exchange module can be a liquid-liquid heat exchanger. For example, in a hybrid vehicle or a gasoline vehicle, the second fluid in the second circuit can be engine cooling water, which exchanges heat with the first fluid in the first water circuit.

[0013] In yet another possible embodiment, the first heat exchange module may be a liquid-gas heat exchanger. For example, the first heat exchange module may be a front-end heat exchanger of a vehicle, through which the first loop water exchanges heat with the outside air.

[0014] The second heat exchange module enables active heat exchange between the first fluid and the cabin air. Active heat exchange is achieved by inputting external energy, allowing heat to be transferred from a lower-temperature object to a higher-temperature object, or vice versa. External energy sources include electric fields, magnetic fields, stress fields, and pressure. For example, when the air conditioning system is operating in cooling mode, the second heat exchange module can transfer heat from the higher-temperature air to the lower-temperature first fluid, or vice versa. When the air conditioning system is operating in heating mode, the second heat exchange module can transfer heat from the lower-temperature first fluid to the higher-temperature air, or vice versa.

[0015] The first heat exchange module may include a first heat exchange channel and a second heat exchange channel, which respectively allow the flow of a first fluid and a second fluid. The second heat exchange module may include a third heat exchange channel, which allows the flow of the first fluid. A water pump can drive the first fluid in the first circuit to flow through the first heat exchange channel, the pipes, and the third heat exchange channel.

[0016] In this embodiment, the second heat exchange module can actively exchange heat between the first fluid flowing through it and the air inside the cabin, enabling rapid and flexible adjustment of the cabin air temperature and improving temperature control. When the piping includes water pipes, the water pipes can be designed more flexibly and are smaller in size than air ducts, saving space.

[0017] How air conditioning systems work:

[0018] When the air conditioning system is operating in cooling mode, the first fluid in the first circuit releases heat to the second fluid flowing through the first heat exchange module as it flows through the first heat exchange module; the first fluid in the first circuit absorbs heat from the air in the cabin as it flows through the second heat exchange module, thereby reducing the air temperature in the cabin.

[0019] When the air conditioning system is operating in heating mode, the first fluid in the first circuit absorbs heat from the second fluid flowing through the first heat exchange module; the first fluid in the first circuit releases heat to the air in the cabin when it flows through the second heat exchange module, thereby increasing the air temperature in the cabin.

[0020] In one possible implementation, the first heat exchange module is located inside or outside the vehicle's cabin.

[0021] The first heat exchange module can be located inside or outside the cabin. When the first heat exchange module is located in the forward cabin, it can prevent the second fluid (e.g., refrigerant) in the second circuit from leaking into the cabin (e.g., the passenger compartment), thus improving the safety of the air conditioning system.

[0022] The first heat exchange module is located inside the vehicle's cabin, and the first circuit is only located inside the cabin. The first circuit does not need to pass through the partition wall between the cabin and the front compartment, which reduces the difficulty of construction and layout of the first circuit.

[0023] In one possible implementation, the second heat exchange module includes a first heat exchange unit, a second heat exchange unit, and a third heat exchange unit, with the first fluid of the first circuit flowing through the first heat exchange unit;

[0024] The first heat exchange unit is used to passively exchange heat between the first fluid flowing through the first heat exchange unit and the first side of the second heat exchange unit. The third heat exchange unit is used to passively exchange heat between the second side of the second heat exchange unit and the air in the cabin. The second heat exchange unit is used to actively exchange heat between the first side of the second heat exchange unit and the second side of the second heat exchange unit.

[0025] The first side is opposite to the second side, with the first side closer to the pipe and the second side farther away from the pipe.

[0026] In this embodiment, the first heat exchange unit can achieve passive heat exchange between the first fluid and the first side of the second heat exchange unit. For example, when the air conditioning system is operating in cooling mode, the temperature of the first side of the second heat exchange unit is higher than the temperature of the first fluid, and the first side of the second heat exchange unit transfers heat to the first fluid; when the air conditioning system is operating in heating mode, the temperature of the first side of the second heat exchange unit is lower than the temperature of the first fluid, and the first fluid transfers heat to the first side of the second heat exchange unit.

[0027] The third heat exchange unit enables passive heat exchange between the second side of the second heat exchange unit and the air inside the cabin. For example, when the air conditioning system is operating in cooling mode, the temperature of the air inside the cabin is higher than the temperature of the second side of the second heat exchange unit, and the air inside the cabin transfers heat to the second side of the second heat exchange unit; when the air conditioning system is operating in heating mode, the temperature of the air inside the cabin is lower than the temperature of the second side of the second heat exchange unit, and the second side of the second heat exchange unit transfers heat to the air inside the cabin.

[0028] The second heat exchange unit enables active heat exchange between its first side and the second side. Active heat exchange allows heat to be transferred from a lower-temperature object to a higher-temperature object, or vice versa. For example, the third heat exchange unit can transfer heat from a lower-temperature object to a higher-temperature object.

[0029] The second heat exchange unit can be located between the first heat exchange unit and the third heat exchange unit.

[0030] The first heat exchange unit may include a first radiator, which may be made of a material with good thermal conductivity, such as metal or plastic with good thermal conductivity. The first radiator may have a heat exchange channel, and the first radiator may be in contact with a first side of the second heat exchange unit. When the first fluid in the first circuit passes through the heat exchange channel of the first radiator, passive heat exchange can be achieved between the first fluid and the first side of the second heat exchange unit.

[0031] The third heat exchange unit may include a second radiator, a fan, an air inlet, and an air outlet. The second radiator may be made of a material with good thermal conductivity, such as metal or plastic. A heat exchange channel may be provided in the second radiator, which may contact the second side of the second heat exchange unit. When the fan blows, air from the cabin enters through the air inlet, passively exchanges heat with the second side of the second heat exchange unit as it passes through the second radiator, and then exits through the air outlet.

[0032] The second heat exchange unit may include any one of a thermoelectric semiconductor cooler (TEC), an electric card cooler, a twist card cooler, a press card cooler, a spring card cooler, or a magnetic card cooler. Taking a TEC as an example, when the air conditioning system is operating in cooling mode, a current in a first direction is applied to the TEC, causing the first side of the TEC to continuously absorb heat from the second side, resulting in a higher temperature on the first side than the second side. When the air conditioning system is operating in heating mode, a current in a second direction is applied to the TEC, causing the second side of the TEC to continuously absorb heat from the first side, resulting in a higher temperature on the second side than the first side. The first and second directions of the current are opposite.

[0033] When the air conditioning system operates in cooling mode, the second heat exchange unit ensures that the temperature on the first side of the second heat exchange unit is higher than the temperature on the second side, and that the second side of the second heat exchange unit transfers heat to the first side. The first fluid in the first circuit releases heat to the second fluid flowing through the first heat exchange module as it passes through it; the first fluid in the first circuit absorbs heat from the first side of the second heat exchange unit as it flows through the first heat exchange unit, and the second side of the second heat exchange unit absorbs heat from the air inside the cabin, thereby lowering the air temperature inside the cabin.

[0034] When the air conditioning system operates in heating mode, the second heat exchange unit ensures that the temperature on the first side of the second heat exchange unit is lower than the temperature on the second side, and heat is transferred from the first side to the second side of the second heat exchange unit. The first fluid in the first circuit absorbs heat from the second fluid flowing through the first heat exchange module; the first fluid in the first circuit releases heat to the first side of the second heat exchange unit as it flows through the first heat exchange unit, and the second side of the second heat exchange unit releases heat to the air inside the cabin, thereby increasing the air temperature inside the cabin.

[0035] The heat exchange between the first and second fluids is passive, transferring heat from the high-temperature fluid to the low-temperature fluid; the heat exchange between the first fluid and the air inside the cabin is active, and the direction of heat transfer can be arbitrarily adjusted as needed; when multiple second heat exchange modules work simultaneously, the heat transfer directions of any two second heat exchange modules can be the same or different, and the power of any two second heat exchange modules can be equal or unequal, enabling flexible temperature adjustment.

[0036] In one possible implementation, the second heat exchange unit includes P cooling plates, which are disposed between the first heat exchange unit and the third heat exchange unit; P is an integer greater than or equal to 1.

[0037] In this embodiment, the second heat exchange unit may be provided with one or more cooling chips. The number of cooling chips included in each of the N second heat exchange units may be equal or unequal, and this embodiment does not limit this.

[0038] In one possible implementation, when P is greater than or equal to 2, P cooling chips are laid flat between the first heat exchange unit and the third heat exchange unit; or, P cooling chips are stacked between the first heat exchange unit and the third heat exchange unit; or, P cooling chips are arranged in a flat, stacked combination between the first heat exchange unit and the third heat exchange unit.

[0039] In this embodiment, P cooling chips are laid flat between the first and third heat exchange units. Laying multiple cooling chips flat increases the heat exchange capacity and efficiency. Alternatively, P cooling chips can be stacked between the first and third heat exchange units. This stacking arrangement allows for a larger temperature difference between the first and second sides, meeting the heat exchange requirements for heating or cooling in practical applications. The combination of laying flat and stacking the P cooling chips between the first and third heat exchange units increases heat exchange capacity and maintains a larger temperature difference between the first and second sides, thus meeting the heat exchange requirements for heating or cooling in practical applications.

[0040] In one possible implementation, the first heat exchange unit includes a first radiator, in which a heat exchange channel is provided, through which the first fluid in the first circuit passes.

[0041] When the first fluid in the first loop passes through the heat exchange channel in the first radiator, passive heat exchange can be achieved between the first fluid and the first side of the second heat exchange unit. The heat exchange channel can be configured in a shape that extends the flow channel length, such as a sawtooth shape, a meandering shape, or a nested coil shape, which can increase the heat exchange area between the first fluid in the heat exchange channel and the first radiator and improve the heat exchange efficiency.

[0042] In one possible implementation, the third heat exchange unit includes a second radiator and a fan, with the radiator located near the second side of the second heat exchange unit and the fan's air outlet facing towards or away from the second radiator.

[0043] In this embodiment, when the fan's air outlet faces the second radiator, the fan is a suction fan, which draws air from the cabin into the third heat exchange unit. The air in the cabin exchanges heat with the second radiator before entering the cabin. When the fan's air outlet is away from the second radiator, the fan is a blowing fan, which blows air from around the second radiator towards the cabin.

[0044] In one possible implementation, when the air conditioning system is in cooling mode, the temperature of the first fluid flowing through the first heat exchange module is higher than the temperature of the second fluid flowing through the first heat exchange module, and the temperature of the first fluid flowing through the second heat exchange module is lower than the temperature of the air in the cabin.

[0045] In one possible implementation, when the air conditioning system is in cooling mode, the temperature of the first fluid flowing into the first heat exchange module is higher than the temperature of the first fluid flowing out of the first heat exchange module, and the temperature of the first fluid flowing into the second heat exchange module is lower than the temperature of the first fluid flowing out of the second heat exchange module.

[0046] In one possible implementation, when the air conditioning system is in cooling mode, the temperature of the first fluid flowing through the first heat exchange unit is lower than the temperature of the first side of the second heat exchange unit, the temperature of the first side of the second heat exchange unit is higher than the temperature of the second side of the second heat exchange unit, and the temperature of the second side of the second heat exchange unit is lower than the temperature of the air inside the cabin.

[0047] In one possible implementation, when the air conditioning system is in heating mode, the temperature of the first fluid flowing through the first heat exchange module is lower than the temperature of the second fluid flowing through the first heat exchange module, and the temperature of the first fluid flowing through the second heat exchange module is higher than the temperature of the air in the cabin.

[0048] In one possible implementation, when the air conditioning system is in heating mode, the temperature of the first fluid flowing into the first heat exchange module is lower than the temperature of the first fluid flowing out of the first heat exchange module, and the temperature of the first fluid flowing into the second heat exchange module is higher than the temperature of the first fluid flowing out of the second heat exchange module.

[0049] In one possible implementation, when the air conditioning system is in heating mode, the temperature of the first fluid flowing through the first heat exchange unit is higher than the temperature of the first side of the second heat exchange unit, the temperature of the first side of the second heat exchange unit is lower than the temperature of the second side of the second heat exchange unit, and the temperature of the second side of the second heat exchange unit is higher than the temperature of the air in the cabin.

[0050] In one possible implementation, when N is greater than or equal to 2, the N second heat exchange modules are connected in series through pipes; or, the N second heat exchange modules are connected in parallel through pipes; or, some of the N second heat exchange modules are connected in series through pipes, and some of the N second heat exchange modules are connected in parallel through pipes.

[0051] In this embodiment, the pipeline layout includes series, parallel, or series-parallel configurations. Series configurations have a simpler pipeline structure, reducing layout complexity and making them suitable for situations with a small number of second heat exchange modules. Parallel configurations are more conducive to individual temperature regulation of each second heat exchange module, resulting in lower energy consumption. Series-parallel configurations have moderate pipeline complexity and energy consumption. Both parallel and series-parallel configurations can be used when there are a large number of second heat exchange modules.

[0052] In one possible implementation, when N second heat exchange modules are connected in parallel via pipes, the pipes include N branch pipes, and the first heat exchange module, the N branch pipes, and the N second heat exchange modules form N branch loops. The first loop includes N branch loops, and the N second heat exchange modules are located in the N branch loops respectively, and the N branch pipes are located in the N branch loops respectively.

[0053] This application provides a specific structure for N second heat exchange modules connected in parallel via pipelines. The pipelines may include N branch pipelines, and the first loop includes N branch loops. Each of the N second heat exchange modules corresponds one-to-one with one of the N branch pipelines, and each branch pipeline corresponds one-to-one with one of the N branch loops. By adopting a parallel structure, each second heat exchange module corresponds to one branch loop, and each branch loop exchanges heat with one second heat exchange module. Temperature regulation of one second heat exchange module will not affect the temperature regulation of other second heat exchange modules, which is beneficial for individual temperature regulation of each second heat exchange module and results in lower energy consumption.

[0054] In one possible implementation, some of the N second heat exchange modules are connected in series via pipes, and some of the N second heat exchange modules are connected in parallel via pipes. The pipes include M branch pipes. The first heat exchange module, the M branch pipes, and the N second heat exchange modules form M branch loops. The first loop includes M branch loops, and at least one of the M branch loops includes two or more second heat exchange modules. M is less than N, and M is an integer greater than or equal to 2.

[0055] In this embodiment, some of the N second heat exchange modules are connected in series via pipes, and some of the N second heat exchange modules are connected in parallel via pipes. This reduces the complexity of the pipe layout and lowers energy consumption.

[0056] In one possible implementation, at least one branch pipe is provided with a switch valve;

[0057] When the switch valve is in the open position, it is used to control the flow of the first fluid in the branch pipeline where the switch valve is located;

[0058] When the switch valve is in the closed state, it is used to control the stop of the first fluid in the branch pipeline where the switch valve is located.

[0059] Each branch pipeline can be equipped with an on / off valve, which can individually control the flow of the primary fluid in each branch pipeline. When the second heat exchange module corresponding to a certain branch pipeline is not working, the on / off valve in that branch pipeline can be closed, thereby stopping the flow of the primary fluid in that branch pipeline and reducing energy consumption. The on / off valve can be electronically controlled or mechanically controlled.

[0060] In one possible implementation, no on / off valves are installed in any of the branch pipes, which can reduce the complexity of the branch pipes.

[0061] In one possible implementation, when the second heat exchange module is in operation, the second heat exchange module adjusts the air outlet parameters of the second heat exchange module in response to the temperature adjustment operation. The air outlet parameters include: air outlet temperature and / or air outlet velocity.

[0062] In this embodiment, each second heat exchange module, when in operation, can adjust the air outlet parameters of its vent in response to the user's temperature adjustment operation. Each second heat exchange module can have its air outlet parameters set independently, and the temperature of each module can be flexibly adjusted.

[0063] In one possible implementation, one or more electronic components are connected in series in the pipe, and a first fluid in the first circuit is used to absorb heat from the electronic components or to release heat to the electronic components.

[0064] The first circuit can be connected in series with one or more electronic components in the vehicle. When the first fluid in the first circuit passes through the electronic components, it can absorb heat from the components or release heat to them, thus meeting the cooling or heating requirements of the electronic components. For example, the first circuit can be used to cool the electronic components, bringing them back to their operating temperature range to meet their cooling needs. Or, for instance, when starting the vehicle in winter, the first circuit can be used to heat the electronic components, bringing them back to their operating temperature range to meet their heating needs.

[0065] For example, electronic components can be mounted on a water-cooled plate, which has an inlet and an outlet. Pipes pass through the inlet and outlet, and heat exchange between the electronic components and the first fluid in the pipes is achieved through the water-cooled plate. The water-cooled plate can be made of a material with good thermal conductivity, such as metal or plastic with good thermal conductivity.

[0066] In one possible implementation, N second heat exchange modules are located in one or more positions within the cockpit:

[0067] Center console, instrument panel, front head air vents, front foot air vents, second-row head air vents, second-row foot air vents, third-row head air vents, third-row foot air vents, seat heating module, seat ventilation module.

[0068] In this embodiment, the second heat exchange module can be placed at any location in the cabin, and can be used to realize the functions of seat heating and seat ventilation, thereby improving the response speed of seat heating.

[0069] In one possible implementation, the N second heat exchange modules are located in fixed or adjustable positions in the first loop.

[0070] The N second heat exchange modules are located in fixed or adjustable positions in the first loop, which can meet the temperature regulation needs of different locations in the cabin.

[0071] In one possible implementation, the second heat exchange unit includes any of the following: a thermoelectric semiconductor cooler (TEC), an electric card cooler, a twist card cooler, a press card cooler, a spring card cooler, or a magnetic card cooler.

[0072] TEC (Transient Electrode Cooler) is a device that utilizes the Peltier effect of semiconductors to achieve heat exchange. Electrocardioid (Electric Card Cooler) is a device that utilizes the electrocardioid effect of materials to achieve heat exchange. Torque-cardioid (also called torsional heat cooler) is a device that utilizes the torsional heat exchange of materials. Compression-cardioid (Compressive Card Cooler) and spring-cardioid (Split-Card Cooler) are devices that utilize the spring-cardioid effect of materials to achieve heat exchange. Magnetic-cardioid (Magnetic Card Cooler) is a device that utilizes the magnetocaloric effect of materials to achieve heat exchange.

[0073] Secondly, embodiments of this application provide a vehicle that includes at least one air conditioning system as described in the first aspect.

[0074] Optionally, the vehicle may include any possible means of transportation used in various scenarios, such as automobiles, trucks, aircraft, drones, slow-moving transport vehicles, spacecraft, or ships. The air conditioning system may be installed in spaces requiring air conditioning, such as vehicles, data centers, shopping malls, office buildings, residential buildings, space capsules, and aircraft cabins; this application embodiment does not impose any limitations on this.

[0098] The following is an exemplary description of an air conditioning system provided in an embodiment of this application.

[0099] Please refer to Figure 1, which is a schematic diagram of an air conditioning system provided in an embodiment of this application. As shown in Figure 1, the air conditioning system may include a first heat exchange module 11, at least one water pump 31 (Figure 1 uses one water pump 31 as an example), a pipe 21, and N second heat exchange modules 12 (Figure 1 uses N equal to 1 as an example). The first heat exchange module 11, the water pump 31, the pipe 21, and the second heat exchange modules 12 form a first loop L1.

The second heat exchange module 12 is used to exchange heat between the first fluid flowing through the second heat exchange module 12 and the air in the cabin. The water pump 31 can be a water-air dual-purpose pump, which can drive liquid or gas to flow in the first loop L1.

[0102] The first heat exchange module 11 enables passive heat exchange between the first fluid and the second fluid. Passive heat exchange requires no external energy input and achieves heat exchange through natural convection and heat conduction. Passive heat exchange allows heat to be transferred from a higher-temperature object to a lower-temperature object. For example, when the air conditioning system is operating in cooling mode, the temperature of the first fluid is higher than that of the second fluid, and the first fluid transfers heat to the second fluid; when the air conditioning system is operating in heating mode, the temperature of the first fluid is lower than that of the second fluid, and the second fluid transfers heat to the first fluid.

[0103] The first fluid can be a liquid or a gas. It can be water or a coolant (e.g., a mixture of water and ethanol) or a gas (e.g., air). The coolant can be a liquid that meets the characteristics of non-freezing, non-corrosiveness, low viscosity, and high specific heat. The second fluid can be a liquid (e.g., water, antifreeze, refrigerant, etc.) or a gas (e.g., air, vaporized refrigerant, etc.).

[0104] The second fluid can pass through the first heat exchange module 11 under the drive of the drive device. The drive device may include a water pump, a compressor, or a fan, etc. For example, when the drive device includes a fan, the second fluid may be air, and the fan may blow air from outside the vehicle into the first heat exchange module 11. The first heat exchange module 11 may perform passive heat exchange between the air flowing through the first heat exchange module 11 and the first fluid in the first heat exchange module 11.

[0105] For example, when the driving device includes a water pump or a compressor, please refer to Figure 2, which is a schematic diagram of another air conditioning system provided in an embodiment of this application. As shown in Figure 2, the air conditioning system may further include a driving device 32 and a refrigerant pipe 22, wherein the driving device 32, the refrigerant pipe 22, and the first heat exchange module 11 form a second circuit L2. The driving device 32 can drive a second fluid in the second circuit L2 to flow in the second circuit L2. The refrigerant pipe 22 is a pipe that allows the second fluid in the second circuit L2 to flow, and the refrigerant pipe 22 may include at least two sub-pipes for connecting the first heat exchange module 11 and the driving device 32 in the second circuit L2.

[0106] In one possible embodiment, the first heat exchange module 11 can be a condenser or an evaporator, and the drive unit 32 can be a compressor. For example, the first heat exchange module 11 can be a condenser or an evaporator in the vehicle's air conditioning unit. When the air conditioning system operates in cooling mode, the second fluid (e.g., refrigerant) in the second circuit L2 absorbs heat in the evaporator, and the first fluid in the first circuit L1 dissipates heat in the evaporator. When the air conditioning system operates in heating mode, the second fluid in the second circuit L2 dissipates heat in the condenser, and the first fluid in the first circuit absorbs heat in the condenser. The second fluid can flow in the second circuit L2 via a Carnot cycle, and the second fluid flows in the second circuit L2 through both evaporation and condensation. Optionally, an expansion valve (not shown in Figure 2) can be provided in the second circuit L2. When the air conditioning system is operating in cooling mode, the second fluid (medium-temperature, low-pressure gas) enters the compressor and becomes a high-temperature, high-pressure gas that enters the condenser. As the high-temperature, high-pressure gas passes through the condenser, it releases heat to the outside air of the vehicle and becomes a medium-temperature, medium-pressure liquid. The medium-temperature, medium-pressure liquid passes through the expansion valve and becomes a low-temperature, low-pressure gas that enters the evaporator. As the low-temperature, low-pressure gas passes through the evaporator, it absorbs heat from the first fluid in the first heat exchange module 11 and becomes a medium-temperature, low-pressure gas. The medium-temperature, low-pressure gas then enters the compressor for the next cycle.

[0107] In another possible embodiment, the first heat exchange module 11 can be a liquid-liquid heat exchanger. For example, in a hybrid vehicle or a gasoline vehicle, the second fluid in the second circuit L2 can be engine cooling water, which exchanges heat with the first fluid in the first water circuit.

[0108] In yet another possible embodiment, the first heat exchange module 11 may be a liquid-gas heat exchanger. For example, the first heat exchange module may be a front-end heat exchanger of a vehicle, through which the first fluid in the first loop L1 exchanges heat with the outside air.

[0109] The second heat exchange module 12 enables active heat exchange between the first fluid and the air inside the cabin. Active heat exchange is achieved by inputting external energy, allowing heat to be transferred from a lower-temperature object to a higher-temperature object, or vice versa. External energy can include electric fields, magnetic fields, stress fields, pressure, etc. For example, when the air conditioning system is operating in cooling mode, the second heat exchange module 12 can transfer heat from the higher-temperature air to the lower-temperature first fluid, or vice versa; when the air conditioning system is operating in heating mode, the second heat exchange module 12 can transfer heat from the lower-temperature first fluid to the higher-temperature air, or vice versa.

[0110] Pipeline 21 may include a liquid pipeline or a gas pipeline. Liquid or gas flow is permitted within pipeline 21. When liquid flow is permitted within pipeline 21, pipeline 21 may be a liquid pipeline (e.g., a water pipe), and when gas flow is permitted within pipeline 21, pipeline 21 may be a gas pipeline.

[0111] Pipeline 21 is a pipe that allows the first fluid to flow in the first loop L1. Pipeline 21 may include at least three sub-pipes for connecting the first heat exchange module 11, the water pump 31 and the second heat exchange module 12 in the first loop L1.

[0112] The first heat exchange module 11 may be provided with a first heat exchange channel and a second heat exchange channel. A first fluid can flow in the first heat exchange channel of the first heat exchange module 11, and a second fluid can flow in the second heat exchange channel of the first heat exchange module 11. The second heat exchange module 12 may be provided with a third heat exchange channel, which allows the first fluid to flow. A water pump 31 can drive the first fluid in the first circuit to flow in the first heat exchange channel, pipe 21, and third heat exchange channel. A drive device 32 can drive the second fluid in the second circuit L2 to flow in the second heat exchange channel.

[0113] In this embodiment, the second heat exchange module can actively exchange heat between the first fluid flowing through it and the air inside the cabin, enabling rapid and flexible adjustment of the cabin air temperature and improving temperature control. When the piping includes water pipes, the water pipes can be designed more flexibly and are smaller in size than air ducts, saving space.

[0114] How air conditioning systems work:

[0115] When the air conditioning system is operating in cooling mode, the first fluid in the first circuit L1 releases heat to the second fluid flowing through the first heat exchange module 11 as it flows through the first heat exchange module 11; the first fluid in the first circuit L1 absorbs heat from the air in the cabin as it flows through the second heat exchange module, thereby reducing the air temperature in the cabin.

[0116] When the air conditioning system is operating in heating mode, the first fluid in the first circuit L1 absorbs heat from the second fluid flowing through the first heat exchange module 11 as it flows through the first heat exchange module 11; the first fluid in the first circuit L1 releases heat to the air in the cabin as it flows through the second heat exchange module, thereby increasing the air temperature in the cabin.

[0117] It is understood that the positions of the first heat exchange module 11, water pump 31, pipe 21, and second heat exchange module 12 in the first loop L1 of Figure 1 are one possible example and do not constitute a limitation on the embodiments of this application. The positions of the first heat exchange module 11, water pump 31, pipe 21, and second heat exchange module 12 can be set at any position in the first loop L1. In some possible implementations, the positions of the drive device 32, refrigerant pipe 22, and first heat exchange module 11 in the second loop L2 of Figure 2 are one possible example and do not constitute a limitation on the embodiments of this application. In some possible implementations, the positions of the drive device 32, refrigerant pipe 22, and first heat exchange module 11 can be set at any position in the second loop L2.

[0118] Optionally, the first heat exchange module 11 is located inside or outside the vehicle's cabin.

[0119] The first heat exchange module 11 can be installed inside or outside the cabin. When the first heat exchange module 11 is installed in the forward cabin, it can prevent the second fluid (e.g., refrigerant) in the second loop L1 from leaking into the cabin (e.g., the passenger compartment), thereby improving the safety of the air conditioning system.

[0120] The first heat exchange module 11 is installed inside the vehicle's cabin. The first circuit L1 is only located within the cabin, eliminating the need for the partition wall between the cabin and the front compartment, thus reducing the difficulty of construction and layout. When the first heat exchange module 11 is installed in the vehicle's cabin, a portion of the refrigerant pipe 22 in the second circuit L2 is inside the cabin, while the other portion is outside. When the second fluid flows through the first heat exchange module 11, it can passively exchange heat with the first fluid flowing through the first heat exchange module 11. When the second fluid flows through the portion of the refrigerant pipe 22 located outside the cabin, it can actively exchange heat with the air or liquid outside the cabin.

[0121] Please refer to Figure 3, which is a structural schematic diagram of a second heat exchange module provided in an embodiment of this application. As shown in Figure 3, the second heat exchange module 12 includes a first heat exchange unit 121, a second heat exchange unit 122, and a third heat exchange unit 123. The first fluid of the first loop L1 flows through the first heat exchange unit 121.

[0122] The first heat exchange unit 121 is used to passively exchange heat between the first fluid flowing through the first heat exchange unit 121 and the first side of the second heat exchange unit 122; the third heat exchange unit 123 is used to passively exchange heat between the second side of the second heat exchange unit 122 and the air in the cabin; and the second heat exchange unit 122 is used to actively exchange heat between the first side of the second heat exchange unit 122 and the second side of the second heat exchange unit 122.

[0123] The first side is opposite to the second side, with the first side closer to pipe 21 and the second side farther away from pipe 21.

[0124] In this embodiment, the first heat exchange unit 121 can achieve passive heat exchange between the first fluid and the first side of the second heat exchange unit 122. For example, when the air conditioning system is operating in cooling mode, the temperature of the first side of the second heat exchange unit 122 is higher than the temperature of the first fluid, and the first side of the second heat exchange unit 122 transfers heat to the first fluid; when the air conditioning system is operating in heating mode, the temperature of the first side of the second heat exchange unit 122 is lower than the temperature of the first fluid, and the first fluid transfers heat to the first side of the second heat exchange unit 122.

[0125] The third heat exchange unit 123 can achieve passive heat exchange between the second side of the second heat exchange unit 122 and the air in the cabin. For example, when the air conditioning system is operating in cooling mode, the temperature of the air in the cabin is higher than the temperature of the second side of the second heat exchange unit 122, and the air in the cabin transfers heat to the second side of the second heat exchange unit 122; when the air conditioning system is operating in heating mode, the temperature of the air in the cabin is lower than the temperature of the second side of the second heat exchange unit 122, and the second side of the second heat exchange unit 122 transfers heat to the air in the cabin.

[0126] The second heat exchange unit 122 enables active heat exchange between its first side and its second side. Active heat exchange allows heat to be transferred from a lower-temperature object to a higher-temperature object, or vice versa. For example, the third heat exchange unit 123 enables heat transfer from a lower-temperature object to a higher-temperature object.

[0127] The second heat exchange unit 122 is disposed between the first heat exchange unit 121 and the second heat exchange unit 122. The first heat exchange unit 121 and the first heat exchange unit 122 can be in direct contact on their first sides, or they can be in contact through a thermal interface material (TIM). The third heat exchange unit 123 and the second heat exchange unit 122 can be in direct contact on their second sides, or they can be in contact through a TIM. This application embodiment does not limit the scope of the contact. The TIM may include thermally conductive gel, silicone grease, etc.

[0128] The first heat exchange unit 121 may include a first radiator 1211, which may be made of a material with good thermal conductivity. For example, the material of the first radiator 1211 may be a metal or a plastic with good thermal conductivity. The metal may be a single metal or a composite metal such as aluminum, magnesium, titanium, iron, copper, aluminum alloy, magnesium alloy, titanium alloy, or iron-carbon alloy. This application embodiment does not limit this. The first radiator 1211 may be provided with a heat exchange channel 1212 (as shown by the dashed box in Figure 3). The first radiator 1211 may be in contact with the first side of the second heat exchange unit 122. The first fluid in the first loop enters the heat exchange channel 1212 from the inlet of the heat exchange channel 1212. When the first fluid in the first loop passes through the heat exchange channel 1212 in the first radiator 1211, passive heat exchange can be achieved between the first fluid and the first side of the second heat exchange unit 122. After the first fluid and the first side of the second heat exchange unit 122 undergo passive heat exchange, the fluid flows out from the outlet of the heat exchange channel 1212. In one possible embodiment, the first radiator 1211 is in direct contact with the first side of the second heat exchange unit 122. In another possible embodiment, the first radiator 1211 and the first side of the second heat exchange unit 122 are in contact via a TIM (thermal inductance measurement), which can reduce contact thermal resistance. The heat exchange channel 1212 can be configured in a shape that extends the channel length, such as a sawtooth shape, a meandering shape, or a nested loop shape, which can increase the heat exchange area between the first fluid in the heat exchange channel 1212 and the first radiator 1211, thereby improving heat exchange efficiency. Optionally, the heat exchange channel 1212 in the first radiator 1211 can also be configured in any other arbitrary shape. This application embodiment does not limit this. Figure 3 shows an example of a sawtooth-shaped heat exchange channel 1212. Exemplarily, the first radiator 1211 also includes a first side and a second side, where the second side of the first radiator 1211 is the side opposite to the first side of the first radiator 1211. Assume that the first side of the first radiator 1211 is the side in contact with the second heat exchange unit 122. The inlet and outlet of the heat exchange channel 1212 can be located on the second side of the first radiator 1211, as shown in Figure 3. Alternatively, by way of example, the inlet and outlet of the heat exchange channel 1212 can be located at any possible position in the first radiator 1211, and this embodiment of the application does not limit this. Optionally, the positions of the inlet and outlet of the heat exchange channel 1212 in Figure 3 can be interchanged.

[0129] The third heat exchange unit 123 may include a second radiator 1231, a fan 1232, an air inlet, and an air outlet. The second radiator 1231 may be made of a material with good thermal conductivity. For example, the material of the second radiator 1231 may be a metal or a plastic with good thermal conductivity. The metal may be various single metals or composite metals such as aluminum, magnesium, titanium, iron, copper, aluminum alloy, magnesium alloy, titanium alloy, or iron-carbon alloy. This application embodiment does not limit this. The second radiator 1231 may contact the second side of the second heat exchange unit 122. When the fan 1232 blows, the air in the cabin enters the third heat exchange unit 123 from the air inlet. When the air in the cabin passes through the second radiator 1231, it undergoes passive heat exchange with the second side of the second heat exchange unit 122, and then exits from the air outlet and enters the cabin. In one possible embodiment, the second radiator 1231 is in direct contact with the second side of the second heat exchange unit 122. In another possible embodiment, the second radiator 1231 is in contact with the second side of the second heat exchange unit 122 via a TIM (thermal inlet / outlet) connection, which can reduce contact thermal resistance. The positions of the air inlet and outlet can be set at any possible location within the third heat exchange unit 123; this embodiment does not limit this. Optionally, the positions of the air inlet and outlet in Figure 3 can be interchanged. Optionally, the number of air inlets and outlets can include one or more; this embodiment does not limit this.

[0130] When the air outlet of fan 1232 faces the second radiator, fan 1232 is an intake fan, which draws air from the cabin into the third heat exchange unit 123. The air in the cabin exchanges heat with the second radiator before entering the cabin. When the air outlet of fan 1232 is away from the second radiator, fan 1232 is a blower fan, which blows air from around the second radiator towards the cabin.

[0131] The second heat exchange unit 122 may include any one of a thermoelectric cooler (TEC), an electric card cooler, a twist card cooler, a press card cooler, a spring card cooler, or a magnetic card cooler. Taking a TEC as an example, the second heat exchange unit 122 is a device that utilizes the Peltier effect of semiconductors to generate cold or heat. Multiple pairs of N-type and P-type semiconductors are disposed between the first and second sides of the TEC. Each pair of N-type and P-type semiconductors is connected by electrodes. When a pair of N-type and P-type semiconductors is energized, under the action of an applied electric field, the current can carry the heat generated within the semiconductors from one side of the TEC to the other side. One side of the TEC continuously absorbs heat, while the other side continuously releases heat, which can cause the temperature of one side of the TEC to rise and the temperature of the other side of the TEC to fall. For example, a power supply is applied to the TEC, and the temperature difference between the first and second sides of the TEC is controlled by adjusting the voltage of the power supply. The direction of the current applied to the TEC is adjusted by adjusting the direction of the voltage of the power supply. Different directions of the current applied to the TEC result in opposite temperature changes on both sides of the TEC. For example, when the air conditioning system is operating in cooling mode, a current in a first direction is applied to the TEC (Transformer Controlled Reactor), causing the first side of the TEC to continuously absorb heat from the second side, resulting in a higher temperature on the first side and thus cooling the second side, which in turn cools the air inside the cabin. When the air conditioning system is operating in heating mode, a current in a second direction is applied to the TEC, causing the second side of the TEC to continuously absorb heat from the first side, resulting in a higher temperature on the second side and thus warming the air inside the cabin. The first and second directions of the current are opposite. For example, the first direction may be the direction from P-type semiconductor to N-type semiconductor, and the second direction may be the direction from N-type semiconductor to P-type semiconductor; or, the first direction may be the direction from N-type semiconductor to P-type semiconductor, and the second direction may be the direction from P-type semiconductor to N-type semiconductor.

[0132] When the air conditioning system operates in cooling mode, the temperature on the first side of the second heat exchange unit 122 is higher than the temperature on the second side, and heat is transferred from the second side of the second heat exchange unit 122 to the first side. The first fluid in the first circuit releases heat to the second fluid flowing through the first heat exchange module as it passes through the first heat exchange module; the first fluid in the first circuit absorbs heat from the first side of the second heat exchange unit 122 as it flows through the first heat exchange unit 121, and the second side of the second heat exchange unit 122 absorbs heat from the air inside the cabin, thereby lowering the air temperature inside the cabin.

[0133] When the air conditioning system operates in heating mode, the temperature on the first side of the second heat exchange unit 122 is lower than the temperature on the second side, and heat is transferred from the first side to the second side of the second heat exchange unit 122. The first fluid in the first circuit absorbs heat from the second fluid flowing through the first heat exchange module; the first fluid in the first circuit releases heat to the first side of the second heat exchange unit 122 when flowing through the first heat exchange unit 121, and the second side of the second heat exchange unit 122 releases heat to the air inside the cabin, thereby increasing the air temperature inside the cabin.

[0134] In one possible embodiment, the second heat exchange unit 122 includes P cooling chips, which are disposed between the first heat exchange unit 121 and the third heat exchange unit 123; P is an integer greater than or equal to 1.

[0135] In this embodiment of the application, the second heat exchange unit 122 may be provided with one or more cooling chips. The number of cooling chips included in each of the N second heat exchange units 122 may be equal or unequal, and this embodiment of the application does not limit it.

[0136] In one possible embodiment, when P is greater than or equal to 2, P cooling chips are laid flat between the first heat exchange unit 121 and the third heat exchange unit 123; or, P cooling chips are stacked between the first heat exchange unit 121 and the third heat exchange unit 123; or, P cooling chips are arranged in a flat, stacked combination between the first heat exchange unit 121 and the third heat exchange unit 123.

[0137] Please refer to Figure 4, which is a schematic diagram of a structure in which multiple cooling chips are laid out in a flat arrangement in a second heat exchange unit according to an embodiment of this application. The second heat exchange unit 122 in Figure 4 uses a TEC as an example. Each cooling chip 1221 in the second heat exchange unit 122 can perform the function of the second heat exchange unit 122 in Figure 3. The cooling chip 1221 also includes a first side and a second side. Applying a current in the first direction to the cooling chip 1221 allows the first side of the cooling chip 1221 to continuously absorb heat from the second side, resulting in a higher temperature on the first side than the second side. Applying a current in the second direction to the cooling chip 1221 allows the second side of the cooling chip 1221 to continuously absorb heat from the first side, resulting in a higher temperature on the second side than the first side. Since the heat released or absorbed by a single cooling chip 1221 is limited, multiple cooling chips 1221 are laid flat between the first heat exchange unit 121 and the third heat exchange unit 123 to form a second heat exchange unit 122, thereby increasing the cooling or heating capacity of the second heat exchange unit 122. As shown in Figure 4, the first side of each cooling chip 1221 is in contact with the first heat exchange unit 121, and the second side of each cooling chip 1221 is in contact with the third heat exchange unit 123. Exemplarily, the number of cooling chips 1221 laid flat is determined according to actual application requirements, and this application embodiment does not limit this.

[0138] Please refer to Figure 5, which is a schematic diagram of a stacked arrangement of multiple cooling chips in a second heat exchange unit according to an embodiment of this application. The second heat exchange unit 122 in Figure 5 uses TEC as an example. As shown in Figure 5, multiple cooling chips 1221 are stacked between the first heat exchange unit 121 and the third heat exchange unit 123. The first side of one cooling chip 1221 is in contact with the first heat exchange unit 121, and the second side of another cooling chip 1221 is in contact with the third heat exchange unit 123 (direct contact or contact via TIM). Of the remaining cooling chips 1221, the second side of each cooling chip 1221 is in contact with the first side of another adjacent stacked cooling chip 1221 (direct contact or contact via TIM). Exemplarily, since the temperature difference formed between a single cooling chip 1221 and the third heat exchange unit 123 is limited, a larger temperature difference can be formed between the first heat exchange unit 121 and the third heat exchange unit 123 by stacking them, thus meeting the heat exchange requirements for heating or cooling in practical applications. For example, the number of stacked cooling chips 1221 is determined according to actual application requirements, and this application embodiment does not limit this.

[0139] Please refer to Figure 6, which is a schematic diagram of a structure in which multiple cooling elements in a second heat exchange unit are arranged in a flat and stacked manner according to an embodiment of this application. As shown in Figure 6, the second heat exchange unit 122 may include multiple cooling elements, which are arranged in a flat and stacked manner between the first heat exchange unit 121 and the third heat exchange unit 123. Figure 6 shows the second heat exchange unit 122 obtained by combining the flat arrangement shown in Figure 4 and the stacking arrangement shown in Figure 5. For example, the second heat exchange unit 122 shown in Figure 6 may be obtained by stacking multiple second heat exchange units 122 shown in Figure 4. Alternatively, the second heat exchange unit 122 shown in Figure 6 may be obtained by flatly arranging multiple second heat exchange units 122 shown in Figure 5. The specific placement methods will not be described in detail. The second heat exchange unit 122 shown in Figure 6 can both increase the cooling or heating capacity of the second heat exchange unit 122 and create a large temperature difference between the first heat exchange unit 121 and the third heat exchange unit 123.

[0140] It is understood that the structures shown in Figures 3 to 6 above are merely examples and do not constitute a limitation on the embodiments of this application.

[0141] For example, in conjunction with the structure of the second heat exchange module 12 described above, the heat exchange channel 1212 of the first heat exchange unit 121 in the second heat exchange module 12 is connected in series in the first loop L1 shown in FIG1. ​​For example, in this first loop L1, the inlet of the heat exchange channel 1212 of the first heat exchange unit 121 in the second heat exchange module 12 can be connected to the water pump 31, and the outlet of the heat exchange channel 1212 of the first heat exchange unit 121 in the second heat exchange module 12 can be connected to the first heat exchange channel of the first heat exchange module 11.

[0142] For example, the flow direction of the first loop L1 is shown in Figure 1. The water pump 31 can drive the first fluid in the first loop L1 to flow to the heat exchange channel 1212 of the first heat exchange unit 121 in the second heat exchange module 12 for heat exchange (heat absorption / heat dissipation). After heat exchange, the first fluid flows to the first heat exchange channel of the first heat exchange module 11 for heat exchange (heat dissipation / heat absorption) and then flows back to the water pump 31, forming the first loop L1.

[0143] In one possible implementation, when N is greater than or equal to 2, the N second heat exchange modules are connected in series through pipe 21; or, the N second heat exchange modules are connected in parallel through pipe 21; or, some of the N second heat exchange modules are connected in series through pipe 21, and some of the N second heat exchange modules are connected in parallel through pipe 21.

[0144] In this embodiment, the layout of the pipes 21 includes series, parallel, or series-parallel configurations. Series configurations have a simpler pipe structure, reducing the complexity of the pipe layout and making them suitable for situations with a small number of second heat exchange modules. Parallel configurations are more conducive to individual temperature regulation of each second heat exchange module, resulting in lower energy consumption. Series-parallel configurations have moderate pipe structure complexity and moderate energy consumption. Both parallel and series-parallel configurations can be used when there are a large number of second heat exchange modules.

[0145] Please refer to Figure 7, which is a schematic diagram of a structure of N second heat exchange modules connected in series according to an embodiment of this application. As shown in Figure 7, N second heat exchange modules (12_1, 12_2, ... 12_N as shown in Figure 7) are connected in series through pipe 21, and the first loop L1 passes through the N second heat exchange modules in sequence. The N second heat exchange modules can be set in different positions in the cabin. The number of water pumps 31 in the first loop L1 is 2. It is understood that Figure 7 is one possible example, and the number of water pumps 31 can be one or more, the number of N can be two or more, the position of the water pumps 31 in the first loop L1 and the position of the N second heat exchange modules can be arbitrarily set, the number and arrangement of the cooling chips in the second heat exchange unit of each second heat exchange module can be the same or different, and when the number of water pumps 31 is multiple, the power of each water pump 31 can be the same or different, which is not limited in this embodiment of the application.

[0146] Please refer to Figure 8, which is a schematic diagram of a structure of N second heat exchange modules connected in parallel according to an embodiment of this application. As shown in Figure 8, the pipe 21 includes N branch pipes (branch pipes 211, 212, ... 21N as shown in Figure 8), and the N second heat exchange modules (12_1, 12_2, ... 12_N as shown in Figure 8) are connected in parallel through the N branch pipes. The first heat exchange module 11, the water pump 31, the branch pipe 211, and the second heat exchange module 12_1 form a branch loop L11; the first heat exchange module 11, the water pump 31, the branch pipe 212, and the second heat exchange module 12_2 form a branch loop L12; and the first heat exchange module 11, the water pump 31, the branch pipe 21N, and the second heat exchange module 12_N form a branch loop L1N.

[0147] It is understood that Figure 8 is one possible example. The number of water pumps 31 can be one or more, the number of N can be two or more, the position of the second heat exchange module in each branch loop can be arbitrarily set, the number and arrangement of the cooling plates in the second heat exchange unit in each second heat exchange module can be the same or different, and when there are multiple water pumps 31, the power of each water pump 31 can be the same or different. This application embodiment does not limit this.

[0148] This application provides a specific structure for N second heat exchange modules connected in parallel via pipelines. The pipelines may include N branch pipelines, and the first loop includes N branch loops. Each of the N second heat exchange modules corresponds one-to-one with one of the N branch pipelines, and each branch pipeline corresponds one-to-one with one of the N branch loops. By adopting a parallel structure, each second heat exchange module corresponds to one branch loop, and each branch loop exchanges heat with one second heat exchange module. Temperature regulation of one second heat exchange module will not affect the temperature regulation of other second heat exchange modules, which is beneficial for individual temperature regulation of each second heat exchange module and results in lower energy consumption.

[0149] Please refer to Figure 9, which is a schematic diagram of a structure of N second heat exchange modules connected in series and parallel according to an embodiment of this application. As shown in Figure 9, the pipe 21 includes M branch pipes (branch pipes 211, 212, ... 21M as shown in Figure 9), and N second heat exchange modules (12_1, 12_2, ... 12_N as shown in Figure 9). The first heat exchange module 11, the water pump 31, the second heat exchange module 12_1 and the branch pipe 211 form a branch loop L11; the first heat exchange module 11, the water pump 31, the second heat exchange module 12_2, the second heat exchange module 12_3 and the branch pipe 212 form a branch loop L12; and the first heat exchange module 11, the water pump 31, the second heat exchange module 12_M and the branch pipe 21M form a branch loop L1M. The second heat exchange modules in any two of the branch loops L11, L12, ..., L1M are connected in parallel, while the second heat exchange modules 12_2 and 12_3 in the branch loop L12 are connected in series.

[0150] In this embodiment, some of the N second heat exchange modules are connected in series via pipe 21, and some of the N second heat exchange modules are connected in parallel via pipe 21. This reduces the layout complexity of pipe 21 and lowers energy consumption.

[0151] It is understood that Figure 9 is one possible example. The number of water pumps 31 can be one or more, the number of N can be two or more, the number of M can be two or more, the position of the second heat exchange module in each branch loop can be arbitrarily set, the number of the second heat exchange module in each branch loop can be one or more, the number and arrangement of the cooling plates in the second heat exchange unit in each second heat exchange module can be the same or different, and when the number of water pumps 31 is multiple, the power of each water pump 31 can be the same or different. This application embodiment does not limit this.

[0152] Optionally, in Figures 8 and 9, pipe 21 also includes a main pipe 23, the cross-sectional area of ​​which is larger than that of the branch pipes (such as 211, 212, etc. in Figure 8 or 9).

[0153] Optionally, in Figures 8 and 9, a manifold can also be installed in the main pipe 23. The manifold can include an outlet chamber (not shown in the figures) and an inlet chamber (not shown in the figures). The outlet chamber is provided with multiple outlet ports, each of which is connected to a branch pipe into which the first fluid flows. The inlet chamber is provided with multiple inlet ports, each of which is connected to a branch pipe out which the first fluid flows.

[0154] In one possible implementation, at least one branch pipe is provided with a switch valve;

[0155] When the switch valve is in the open position, it is used to control the flow of the first fluid in the branch pipeline where the switch valve is located;

[0156] When the switch valve is in the closed state, it is used to control the stop of the first fluid in the branch pipeline where the switch valve is located.

[0157] Each branch pipeline can be equipped with an on / off valve, which can individually control the flow of the primary fluid in each branch pipeline. When the second heat exchange module corresponding to a certain branch pipeline is not working, the on / off valve in that branch pipeline can be closed, thereby stopping the flow of the primary fluid in that branch pipeline and reducing energy consumption. The on / off valve can be electronically controlled or mechanically controlled.

[0158] In one possible implementation, no on / off valves are installed in any of the branch pipes, which can reduce the complexity of the branch pipes.

[0159] Please refer to Figure 10, which is a schematic diagram of a branch pipeline with a switch valve provided in an embodiment of this application. As shown in Figure 10, a switch valve 41 is provided in branch pipeline 211, a switch valve 42 is provided in branch pipeline 212, and a switch valve 4N is provided in branch pipeline 21N. For example, when the second heat exchange module 12_1 is not working, and the second heat exchange modules 12_2 and 12_N are working, switch valve 41 can be closed, and switch valves 42 and 4N can be opened, thereby controlling the first fluid in branch pipeline 211 to stop flowing and controlling the first fluid in branch pipelines 212 and 21N to flow. At this time, the water pump 31 can drive the first fluid to flow in branch pipelines 211 and 21N. The first fluid does not need to pass through the second heat exchange module 12_1, and the first fluid does not need to undergo heat exchange in the second heat exchange module 12_1, thereby reducing energy consumption. If the switch valve 41 is opened, the first fluid will pass through the second heat exchange module 12_1. Since the second heat exchange module 12_1 is not working, the first fluid will still undergo heat exchange when passing through the second heat exchange module 12_1, which will result in energy loss.

[0160] It is understood that each branch pipe in Figure 10 is equipped with a switch valve. Optionally, one or more switch valves may be installed in some branch pipes, some branch pipes may not be equipped with switch valves, or none of the branch pipes may be equipped with switch valves. This application embodiment does not limit this.

[0161] In one possible implementation, N second heat exchange modules are located in one or more positions within the cockpit:

[0162] Center console, dashboard, front head air vents, front foot air vents, second-row head air vents, second-row foot air vents, third-row head air vents, third-row foot air vents, seat heating module, seat ventilation module, seat heating / ventilation module.

[0163] Please refer to Figure 11, which is a structural schematic diagram of an air conditioning system in a vehicle according to an embodiment of this application. As shown in Figure 11, the second heat exchange module is exemplified by a TEC module, which is a second heat exchange module with a TEC second heat exchange unit. Taking N=4 as an example, TEC module 1 is located on the center console, TEC module 2 is located between the two seats in the second row (e.g., near the head air vents of the second row), and TEC modules 3 and 4 are respectively located near the two seats in the third row (e.g., near the head air vents of the third row). The four TEC modules in Figure 11 are connected in series via pipes.

[0164] The TEC module can be controlled while powered on. The TEC module's cooling and heating are instantaneous. The TEC module can directly exchange heat with the air in the cabin. Compared to absorbing or releasing heat from the outside environment and then exchanging heat multiple times through refrigerant and water circulation before exchanging heat with the cabin air, the TEC module's response speed is greatly improved, with almost no waiting time.

[0165] Because water has a specific heat capacity thousands of times that of air, the flow rate required to transport the same amount of heat is greatly reduced. When transporting the same amount of heat, the cross-sectional area of ​​the pipe can be smaller than that of the air duct, thus saving the space required to lay the pipe and saving space in the cabin.

[0166] In this embodiment, the second heat exchange module can be placed at any location in the cabin, and can be used to realize the functions of seat heating and seat ventilation, thereby improving the response speed of seat heating.

[0167] This application embodiment uses pipes instead of traditional air ducts to deliver hot / cold water to the rear seats. For large vehicles, such as multi-purpose vehicles (MPVs), the cooling or heating effect of the rear seats is poor if traditional air ducts are used. Using the pipes of this application embodiment improves the cooling or heating effect, thereby enhancing the user experience in the cabin. A TEC module is installed around the seats to achieve heat exchange between the first fluid in the pipes and the air in the cabin. The TEC, when powered on, can heat or cool the air with a fast response and a better thermal experience. The TEC modules are independent of each other, allowing them to meet the comfort temperature requirements of different passengers and achieve multi-temperature zone control.

[0168] The number of TEC modules can be set to be the same as, more than, or less than the number of seats. The design is flexible and tailored to the performance requirements of the TEC modules. The TEC modules can be positioned in a fixed location within the cabin or in a movable location. When the TEC modules are positioned in a fixed location, their air outlets are designed to be adjustable, and there can be one or more air outlet directions. For example, TEC module 2 in Figure 11 has two air outlet directions, each facing one of the two seats in the second row. The placement of the TEC modules does not need to exceed the liquid level of the vehicle's first fluid reservoir, facilitating the injection and discharge of the first fluid into the pipes. The first fluid reservoir can be a container holding the first fluid.

[0169] In Figure 11, there are 4 TEC modules and 6 seats in the vehicle. The number of TEC modules is less than the number of seats, which saves costs. Specifically, the two front seats share one TEC module: TEC module 1, and the two second-row seats share one TEC module: TEC module 2.

[0170] The vehicle in Figure 11 is an example with three rows of seats. The air conditioning system of this application embodiment can also be used for vehicles with one row of seats, vehicles with two rows of seats, and vehicles with four or more rows of seats. This application embodiment does not limit the scope of the application.

[0171] Please refer to Figure 12, which is a structural schematic diagram of another in-vehicle air conditioning system provided in an embodiment of this application. As shown in Figure 12, the second heat exchange module is exemplified by a TEC module, which is a second heat exchange module with a TEC second heat exchange unit. Taking N=10 as an example, TEC module 1 is located on the center console, TEC module 2 is located between the two seats in the second row (e.g., near the second-row head air vents), TEC modules 3 and 4 are located near the two seats in the third row (e.g., near the third-row head air vents), TEC modules 5 and 6 are located in the seat heating / ventilation modules of the two front seats, TEC modules 7 and 8 are located in the seat heating / ventilation modules of the two second-row seats, and TEC modules 9 and 10 are located in the seat heating / ventilation modules of the two third-row seats. The 10 TEC modules in Figure 12 are connected in series via pipes. The seat heating / ventilation module can be a module that supports both seat heating and seat ventilation functions.

[0172] In Figure 12, each seat in the vehicle can be equipped with an individual seat heating / ventilation module, which can be implemented through a TEC module. For example, hot air is blown out of the TEC module's vents to achieve seat heating; cold air is blown out of the TEC module's vents to achieve seat ventilation. Due to the fast response speed of the TEC module, the response speed of seat heating and ventilation is improved.

[0173] In one possible implementation, the first heat exchange module is located in the cockpit or the forward cabin. Figure 11 shows an example where the first heat exchange module is located in the forward cabin.

[0174] The first heat exchange module can be located in either the cockpit or the forward cabin. When the first heat exchange module is located in the forward cabin, it prevents the leakage of the second fluid (e.g., refrigerant) from the second circuit into the passenger compartment, improving the safety of the air conditioning system. When the first heat exchange module is located in the cockpit, the first circuit is only within the cockpit, eliminating the need for the partition wall between the cockpit and the forward cabin, thus reducing the difficulty of construction and layout for the first circuit.

[0175] In one possible implementation, the N second heat exchange modules are located in fixed or adjustable positions in the first loop.

[0176] The N second heat exchange modules are located in fixed or adjustable positions in the first loop, which can meet the temperature regulation needs of different locations in the cabin.

[0177] In one possible implementation, when the second heat exchange module is in operation, the second heat exchange module adjusts the air outlet parameters of the second heat exchange module in response to the temperature adjustment operation. The air outlet parameters include: air outlet temperature and / or air outlet velocity.

[0178] In this embodiment, each second heat exchange module, when operating, can adjust its outlet air parameters in response to user temperature control operations. Each second heat exchange module can have its outlet air parameters set independently, and its temperature can be flexibly adjusted, thereby flexibly regulating the temperature in different areas of the cabin. It is understood that the outlet air parameters of each second heat exchange module can be independently adjusted according to the needs of the user in the cabin. The outlet air parameters of each second heat exchange module can be the same or different; this embodiment does not impose such limitations. For example, under different user temperature control operations, among the N second heat exchange modules, some outlets will emit hot air, while others will emit cold air.

[0179] In Figures 11 and 12, the temperature of each TEC module can be adjusted individually. For example, a touchscreen display can be provided on the panel of the TEC module, which responds to the user's temperature adjustment operation, thereby adjusting the airflow parameters of the TEC module's outlet. The airflow parameters of each TEC module's outlet can be the same or different. For example, user 1 adjusts the temperature on the touchscreen display of TEC module 1, causing the TEC in TEC module 1 to apply a current in a first direction, thereby causing the outlet of TEC module 1 to blow out cold air. User 2 adjusts the temperature on the touchscreen display of TEC module 2, causing the TEC in TEC module 2 to apply a current in a second direction, thereby causing the outlet of TEC module 1 to blow out hot air.

[0180] The user's temperature adjustment operation can be a touch operation on a touch screen, or a pressing or rotating operation of a mechanical button, etc., and this application embodiment does not limit it.

[0181] In one possible implementation, one or more electronic components are connected in series in the pipe, and a first fluid in the first circuit is used to absorb heat from the electronic components or to release heat to the electronic components.

[0182] The conduit can connect one or more electronic components in the vehicle, allowing the first fluid in the first circuit to absorb or release heat from the electronic components as it passes through them, thus meeting the cooling or heating requirements of the components. For example, the conduit can cool the electronic components to bring them within their operating temperature range, thus meeting their cooling needs. Conversely, it can heat the electronic components when starting the vehicle in winter, bringing them within their operating temperature range, thus meeting their heating needs. The electronic components can be connected at any point in the conduit, and the number of electronic components connected in series in the conduit can be one or more. The electronic components can be located anywhere in the vehicle; this embodiment does not impose any limitations.

[0183] For example, electronic components can be mounted on a water-cooled plate, which has an inlet and an outlet. Pipes pass through the inlet and outlet, and heat exchange between the electronic components and the first fluid in the pipes is achieved through the water-cooled plate. The water-cooled plate can be made of a material with good thermal conductivity, such as metal or plastic with good thermal conductivity.

[0184] Please refer to Figure 13, which is a schematic diagram of an electronic component connected in series in a pipe of an air conditioning system according to an embodiment of this application. As shown in Figure 13, the electronic component is connected in series in the pipe between TEC module 1 and TEC module 2. Figure 13 uses a single electronic component connected in series as an example. When the temperature of the first fluid in the pipe is lower than the temperature of the electronic component, it can dissipate heat from the electronic component; when the temperature of the first fluid in the pipe is higher than the temperature of the electronic component, it can heat the electronic component.

[0185] This application provides a vehicle that includes at least one of the above-described air conditioning systems.

[0186] Optionally, the vehicle may include any possible means of transportation used in various scenarios, such as automobiles, trucks, aircraft, drones, slow-moving transport vehicles, spacecraft, or ships.
