[0002] In related technologies, current transport vehicles (such as heavy-duty refrigerated transport vehicles) mainly face the following key issues:
[0003] 1) The complexity of multi-system coordination and integration: Long-distance transport vehicles usually require multiple thermal management subsystems. The heat demand and heat dissipation of each subsystem vary significantly with the changes in operating conditions, and the temperature control requirements are also different.
[0004] 2) A large amount of waste heat generated by the fuel cell system is not effectively recovered and utilized, resulting in significant energy waste and hindering the improvement of vehicle range;
[0005] 3) Transport vehicles, such as heavy-duty refrigerated transport vehicles, have extremely high requirements for the performance of refrigeration systems, resulting in huge power consumption, shortening the driving range, and indirectly increasing the total life cycle operating cost. This has become the main bottleneck restricting the development of long-distance pure electric refrigerated transport vehicles.
[0006] 4) Currently, environmental regulations are becoming increasingly stringent globally. Traditional fuel-powered cold chain transport vehicles are limited by their emission levels, which will significantly restrict their future development space and is inconsistent with the low-carbon strategy.

[0054] Figure 1 This is an optional structural diagram of an integrated thermal management system for a transport vehicle provided in an embodiment of this application. The system includes a heat pump air conditioning module, an adsorption refrigeration air conditioning module, a power battery module, a motor thermal management module, a fuel cell thermal management module, a heating and ventilation module, and a central heat exchange module.
[0055] The central heat exchange module includes multiple fluid input terminals and multiple fluid output terminals. The fluid input terminals and fluid output terminals are used to connect with the target module to achieve fluid communication. The target module is one of the following: heat pump air conditioning module, adsorption refrigeration air conditioning module, power battery module, motor thermal management module, fuel cell thermal management module, and HVAC module.
[0056] The heat pump air conditioning module, adsorption refrigeration air conditioning module, power battery module, motor thermal management module, fuel cell thermal management module, and HVAC module are coupled through a central heat exchange module. The heat pump air conditioning module exchanges heat through a refrigerant (such as R134a).

A central heat exchange module, utilizing its efficient heat exchange capabilities and flexible fluid distribution functions, can recover and reuse this waste heat. For example, the waste heat can be used to heat the driver's cabin, improving driving comfort in low-temperature environments; it can also assist in the thermal management of the power battery, ensuring it operates within its optimal temperature range and extending its lifespan; furthermore, water from the adsorption-type refrigeration air conditioning module can absorb this waste heat through the central heat exchange module, eliminating the need for electricity compared to using a heat pump air conditioning module, thus significantly reducing energy consumption for cargo compartment cooling and heating. Simultaneously, this integrated thermal management system simplifies the system structure, reduces vehicle weight and space usage, and opens up more possibilities for vehicle design and performance enhancement.

[0097] Steps 2.1 and 2.2 are performed alternately to achieve continuous cooling.
[0098] When an adsorption-type air conditioner is in heating mode:
[0099] Step 3.1: When At this time, the cargo hold temperature is low and heating is required; adjust the adsorption refrigeration air conditioner to the heating position, and open the first three-way valve at the A input end of the adsorption bed. The corresponding channel, the second three-way valve opens the output end of adsorption bed A. The corresponding channels are: the third three-way valve opens the channel corresponding to the input end of the second evaporator, and the fourth three-way valve opens the input end of adsorption bed B. The corresponding passageway. The thermal management system uses adsorption-based refrigeration and heating for the cargo hold.
[0100] Step 3.2: When At this time, the cargo hold temperature is low and heating is required; adjust the adsorption refrigeration air conditioner to the heating position, and open the first three-way valve at the A input end of the adsorption bed.

[0105] 4) Motor thermal management working mode: The motor thermal management working mode is divided into motor circuit heat preservation circulation and first heat exchanger heat dissipation. Indicates motor temperature. This indicates the upper limit value for setting the motor temperature. This indicates the lower limit value for setting the motor temperature;
[0106] During the heat preservation cycle of the motor circuit: when At this point, the motor temperature is low and heating is required; the motor circuit is switched to the heat preservation and circulation position, the seventh three-way valve opens the corresponding channel at the input end of the second water pump, the second water pump starts, and self-circulation begins. During this process, the thermal management system performs heat preservation and circulation of the motor circuit.
[0107] When the first heat exchanger dissipates heat: At this point, the motor temperature is high and requires cooling; the motor is adjusted to the first heat exchanger cooling position, the seventh three-way valve opens the channel corresponding to the first heat exchanger input terminal ⑧, and the second water pump starts. During this process, the thermal management system cools the motor using the first heat exchanger.
[0108] 5) Fuel Cell Thermal Management Operating Modes: The fuel cell thermal management operating modes are divided into fuel cell loop insulation circulation, fuel cell waste heat utilization, and overload waste heat dissipation. Among these, Indicates the temperature of the fuel cell. This indicates the setting of the upper limit temperature for the fuel cell. This indicates the setting of the intermediate limit temperature for the fuel cell. This indicates the setting of the lower limit temperature for the fuel cell.
[0109] During the fuel cell circuit insulation cycle: when At this point, the fuel cell temperature is low and heating is required. The system is switched to the fuel cell loop circulation position. The eighth three-way valve opens the channel corresponding to the third water pump input, and the ninth three-way valve opens the channel corresponding to the fuel cell input. The fuel cell starts, and the third water pump also starts. During this process, the thermal management system maintains the fuel cell loop temperature and circulates.
[0110] When utilizing waste heat from fuel cells: At this point, the fuel cell has reached normal operating temperature and requires heat dissipation.

The fuel cell and the third water pump continue to operate. In this process, the thermal management system utilizes the fuel cell waste heat.
[0111] When dissipating waste heat under overload: At this point, the fuel cell temperature is high, and the first heat dissipation unit is no longer sufficient for adequate heat dissipation. The system is then switched to the overload waste heat dissipation position, and the ninth three-way valve opens the channel corresponding to the input of the heat dissipation unit, while the others remain unchanged from the fuel cell waste heat utilization position. During this process, the thermal management system dissipates overload waste heat from the fuel cell.
