[0003] Currently, small and medium-sized construction machinery typically uses the above-mentioned method 3 for thermal management systems. However, the piping of method 3 is relatively complex and the integration rate is low, resulting in messy pipe connections throughout the vehicle. Utility Model Content

[0034] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0035] The thermal management system and operating machinery according to this utility model are described below with reference to the accompanying drawings.

[0036] like Figure 1 The diagram shown is a front view schematic diagram of a thermal management system provided according to an embodiment of the present utility model; as shown... Figure 2 The diagram shown is a side view of a thermal management system provided according to an embodiment of the present invention; as shown... Figure 3 The diagram shown is a schematic representation of the internal structure of the integrated box 20 according to an embodiment of the present invention. The thermal management system provided in this embodiment of the present invention includes:

[0037] Base plate 10;

[0038] The integrated box 20 is installed on the base plate 10, and the integrated box 20 is located at one end of the base plate 10;

[0039] Multiple thermal management function modules 30 are all integrated and installed in the integrated box 20;

[0040] Multiple heat treatment pipes 40 are arranged in parallel and spaced apart, and are all located at the end of the base plate 10 away from the integrated box 20. The multiple heat treatment pipes 40 are connected to multiple heat management function modules 30, and the multiple heat management function modules 30 are used to transfer heat through the multiple heat treatment pipes 40.

[0041] In the prior art, the thermal management system of small and medium-sized operating machinery typically adopts an arrangement that integrates the thermal management system of the cab and the battery, while isolating the thermal management system of the electric drive. However, the above arrangement often suffers from low integration and messy piping connections. This utility model provides a thermal management system to solve the above problems.

[0042] Specifically, the thermal management system provided by this utility model includes a base plate 10, an integrated box 20, multiple thermal management functional modules 30, and multiple heat treatment pipelines 40. The base plate 10 supports the entire thermal management system, ensuring stable installation and operation of all components. The integrated box 20 serves as the mounting carrier for the thermal management functional modules 30; its compact and rational design facilitates the efficient integration of multiple thermal management functional modules 30. These functional modules achieve heat transfer and control between each other through internal connection structures, thereby meeting the thermal management requirements of components such as the cab, battery, and electric drive. At the end of the base plate 10 opposite to the integrated box 20, multiple heat treatment pipelines 40 are arranged in parallel at intervals, connecting to the thermal management functional modules 30 within the integrated box 20, forming a complex heat transfer network. These pipelines not only handle heat transfer but also achieve precise heat control through specific design.

[0043] The aforementioned thermal management system integrates multiple thermal management functional modules 30 into the integration box 20, making the entire thermal management system more compact and reducing its space occupation. Simultaneously, by optimizing the routing of the heat treatment piping 40, the piping connections are made more orderly, avoiding a messy piping layout and improving the reliability and maintainability of the thermal management system.

[0044] In one embodiment, such as Figure 2 As shown, the integrated box 20 has multiple mounting holes 21 on the side near the heat treatment pipes 40, with each heat treatment pipe 40 correspondingly inserted into one of the mounting holes 21. This design not only facilitates the installation and fixation of the heat treatment pipes 40, but also ensures precise alignment between the pipes and the integrated box 20, optimizes the pipe routing layout, and improves the assembly efficiency and stability of the entire thermal management system. In a specific embodiment, the design of the mounting holes 21 also considers sealing to prevent unnecessary heat leakage during transmission, thereby further improving the performance of the thermal management system.

[0045] In one embodiment, such as Figure 1 As shown, the thermal management system also includes a locking assembly for locking multiple heat treatment pipes 40 to the base plate 10. The locking assembly can lock the heat treatment pipes 40 and the base plate 10, making the entire thermal management system more stable and preventing the pipes from loosening or being damaged due to vibration or other reasons during the operation of the machinery.

[0046] In one embodiment, such as Figure 1As shown, the locking assembly includes multiple clamping strips 51 and multiple locking elements 52. The clamping strips 51 are located above multiple heat treatment pipelines 40 and are spaced apart along the axial direction of the heat treatment pipelines 40. The locking elements 52 are used to lock the base plate 10 and the clamping strips 51 together, thereby locking the heat treatment pipelines 40 above the base plate 10. This design makes the installation and disassembly of the locking assembly more convenient, while also ensuring the stability and reliability of the heat treatment pipelines 40 during long-term use. The combined use of the clamping strips 51 and the locking elements 52 can also effectively prevent the heat treatment pipelines 40 from deforming or being damaged due to uneven stress, further extending the service life of the heat management system.

[0047] In one embodiment, the multiple thermal management functional modules 30 include a cab thermal functional module, a battery thermal functional module, and an electric drive thermal functional module. These modules provide thermal management solutions for the cab, battery, and electric drive, respectively. The cab thermal functional module controls the cab temperature by adjusting the output of heat and cold sources according to the temperature requirements, ensuring the driver can work in a comfortable environment. The battery thermal functional module focuses on the temperature management of the battery module, maintaining the battery within its optimal operating temperature range by precisely controlling the liquid flow in the heat treatment pipeline 40, thereby extending battery life and improving performance. The electric drive thermal functional module is responsible for the temperature control of the electric drive system, ensuring the electric drive components operate with high efficiency and low loss. These functional modules achieve heat transfer and control among themselves through the connection structure within the integrated box 20, enabling precise regulation of the overall thermal management of the operating machinery.

[0048] In one embodiment, such as Figure 4The diagram shows the piping connection principle of the thermal management system provided according to an embodiment of the present invention. The thermal management system also includes a cold source and a heat source. Multiple heat treatment pipes 40 include a cab heating pipe section connected to the heat source and a cab cooling pipe section connected to the cold source. The cab thermal function module includes a heating water pump and a refrigerant shut-off valve. The heating water pump is connected to the cab heating pipe and is used to transfer heat from the heat source to the cab heating assembly. The refrigerant shut-off valve is connected to the cab cooling pipe and is used to switch the cold source and the cab cooling assembly on / off. The heating water pump can efficiently transfer heat to the cab heating assembly according to the heat demand from the heat source, achieving a rapid and stable increase in the cab temperature. Simultaneously, the refrigerant shut-off valve can precisely control the on / off connection between the cold source and the cab cooling assembly to meet the cooling needs of the cab, ensuring the driver works in a suitable temperature environment and improving the operating comfort and work efficiency of the machinery. In a specific embodiment, the heat source is a water heater, the cold source is a condenser, the heating assembly includes a heating core, and the cooling assembly includes an evaporator and a thermal expansion valve. The heating element transfers heat from the heat source to the air entering the cab, thus heating the cab. The evaporator absorbs heat from the cab and, in conjunction with the throttling effect of the thermal expansion valve, evaporates the refrigerant to produce a cooling effect, thereby lowering the cab temperature. Furthermore, the expansion tank provides the necessary liquid replenishment and expansion space for the thermal management system, ensuring stable system operation. In a preferred embodiment, the expansion tank is connected to the heat treatment pipeline 40 to monitor and regulate the liquid pressure and level within the system in real time, further improving the reliability and safety of the thermal management system.

[0049] In one embodiment, such as Figure 4 As shown, the multiple heat treatment pipes 40 also include a first pipe section and a second pipe section connected end to end. The first pipe section and the second pipe section form a closed battery temperature regulation circuit. The first pipe section is connected to a heat source, and the second pipe section is arranged around the circumference of the battery module. The battery thermal function module includes: a first water circuit shut-off valve, a second water circuit shut-off valve, a self-circulating water pump, and a refrigeration heat exchanger. The first water circuit shut-off valve and the second water circuit shut-off valve are located on the battery temperature regulation circuit and are respectively close to the beginning and end of the first pipe section. The first water circuit shut-off valve and the second water circuit shut-off valve are used to open and close the battery temperature regulation circuit. The inlet and outlet of the self-circulating water pump are respectively connected to the two ends of the second pipe section and are used to drive the liquid in the second pipe section to circulate. The refrigeration heat exchanger is connected to the cab refrigeration pipe and is used to cool the liquid in the second pipe section.

[0050] Precise control of the first and second water circuit shut-off valves allows the battery temperature regulation circuit to activate rapidly when needed, regulating the battery module temperature. When the battery requires heating, both valves open, allowing heat from the heat source to enter the battery temperature regulation circuit through the first pipe section, heating the liquid in the second pipe section and thus the battery module. When the battery requires cooling, both valves close, the self-circulating water pump starts, driving the liquid in the second pipe section to circulate. Simultaneously, the heat exchanger connects to the cab's cooling pipes, utilizing the cooling energy from the cold source to cool the liquid in the second pipe section, thereby cooling the battery. This design not only improves the efficiency of battery thermal management but also ensures the battery operates within its optimal temperature range, extending its lifespan. Furthermore, the self-circulating water circuit shut-off valves can shut off the liquid in the second pipe section when heating or cooling is not required, stopping the self-circulation and reducing unnecessary energy loss, thus improving the overall energy efficiency of the thermal management system.

[0051] In one embodiment, the cold source is a condenser, and the heat source is a water heater, which is integrated into the integrated box 20. A condenser is a device used to cool and condense gas or vapor into a liquid, typically used in the refrigeration section of a thermal management system. As a cold source, the condenser works in conjunction with components such as the cab's refrigeration pipes to meet the cab's cooling needs. A water heater is a device that generates heat, typically used in the heating section of a thermal management system. Integrating the water heater into the integrated box 20 makes the thermal management system more compact and also facilitates efficient heat transfer and control. This design not only improves the integration level of the thermal management system but also optimizes the heat transfer path, reduces heat loss, and improves the overall efficiency of the thermal management system. Furthermore, integrating the water heater into the integrated box 20 also facilitates the maintenance and upkeep of the thermal management system, reducing system complexity and maintenance costs.

[0052] In one embodiment, the multiple heat treatment pipes 40 further include a third and a fourth pipe section forming an electric drive temperature control loop. The electric drive thermal function module includes an electric drive temperature control component (not shown in the figure) and an electric drive water pump (not shown in the figure). The electric drive temperature control component is connected to the electric drive temperature control loop, and the electric drive water pump is connected to the electric drive temperature control loop and is used to drive the self-circulation of liquid in the electric drive temperature control loop. The electric drive temperature control component can heat or cool the liquid in the electric drive temperature control loop according to the temperature requirements of the electric drive component, thereby maintaining the electric drive component within its optimal operating temperature range. The electric drive water pump is responsible for driving the self-circulation of liquid in the electric drive temperature control loop, ensuring efficient heat transfer and regulation. This design not only improves the efficiency of electric drive thermal management but also helps extend the service life of the electric drive component and improve the overall performance and reliability of the operating machinery.

[0053] The aforementioned thermal management system enables efficient integration and heat transfer of multiple thermal management functional modules 30, improving the overall integration level of the thermal management system. Simultaneously, by optimizing the routing of the heat treatment pipes 40, messy pipe connections are avoided, resulting in a more compact structure and reduced space occupation for the entire thermal management system. Furthermore, the thermal management system includes locking components to secure the multiple heat treatment pipes 40 to the base plate 10, enhancing the stability and reliability of the thermal management system. These designs not only improve the performance of the thermal management system but also reduce its complexity and maintenance costs, providing strong support for the efficient operation of the machinery.
