[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] Combined with appendix Figure 1-7 As shown, an arrangement structure of a thermal management integrated unit for a heavy-duty electric truck includes: a heat pump integrated unit 5 with a square sheet metal bracket, which integrates the heat pump integrated unit, fuel heater unit, diesel tank, expansion tank and mounting bracket; several mounting brackets 6 are arranged opposite each other on the left and right sides of the square sheet metal bracket, and the mounting brackets 6 are connected to the vehicle frame by bolts to set the entire arrangement structure between the left and right vehicle frames; and rubber pads are embedded on the mounting brackets 6 to contact the top of the vehicle frame through the rubber pads.

[0031] The layout structure mainly includes the following components: fuel heater unit 1, diesel tank 3, expansion tank 4, heat pump integrated unit 5, and mounting bracket 6. The heat pump integrated unit 5 is integrated and installed through its own square sheet metal bracket. Several mounting brackets 6 are fixed on its left and right sides by fasteners, so that the fuel heater unit 1, diesel tank 3, and expansion tank 4 can be set on the square sheet metal bracket through the mounting brackets 6, so as to achieve efficient integration and stable operation of the thermal management integrated unit.

[0032] Specifically, in this embodiment, the fuel heater unit 1 is mounted on a square sheet metal bracket via the fuel heater transition bracket 2, and the fuel heater unit 1 is located on the lower left side of the heat pump integrated unit 5, which facilitates connection with the fuel heater.

[0033] The fuel heater unit 1 is primarily a device that provides a heat source for the battery and the heater. It is connected to the fuel heater to supply a stable, non-power-consuming heat source to the battery and heater system using the heat generated by the combustion of the fuel heater. The fuel heater unit 1 is mounted to one side of the fuel heater transition bracket 2 using screws, bolts, or other fasteners. Preferably, the fuel heater unit 1 is located below the heat pump integrated unit 5.

[0034] The fuel heater transition bracket 2, serving as a bridge connecting the fuel heater unit and the mounting bracket, is designed with full consideration of the spatial layout and connection strength requirements between different components. In this embodiment, preferably, the fuel heater transition bracket 2 has a thickness T = 3.5mm, is made of Q235 and SPCC materials, has a 5mm long flange, and features a reinforcing rib design with a recessed groove on the flange.

[0035] Diesel tank 3 is the main device for storing diesel fuel. It is connected to the fuel heater to provide sufficient fuel for combustion. 5L and 10L diesel tanks are available. The tank is made of PA66 stainless steel and contains a level sensor that communicates with the instrument panel. When the level drops to one-fifth, the sensor sends a signal to the instrument panel to remind passengers to refuel.

[0036] Expansion tank 4 is primarily a device for storing coolant and achieving gas-liquid separation in the cooling system. It provides crucial support for the continuous and stable operation of the cooling system. The expansion tank is made of PP material to ensure light transmittance, allowing the driver to easily observe the coolant level. It has four internal chambers to allow for sufficient interaction between the liquid and gas, thus achieving liquid-gas separation.

[0037] The core function of the heat pump integrated unit 5 is to achieve efficient heat transfer and precise regulation of the entire vehicle, providing crucial support for the stable operation of the vehicle's thermal management system. The heat pump integrated unit 5 consists of an electronic water pump, a battery heat exchanger, a water-cooled condenser, a three-way valve, a four-way valve, an EXV valve, a water-cooled unit, a fuel-side unit, a temperature sensor, water pipes, air conditioning pipes, and a square sheet metal bracket.

[0038] Mounting bracket 6 plays a crucial role in securing the heat pump integrated unit 5, ensuring its stability during vehicle operation.

[0039] Bolt 7 serves as a fastener, which secures the heat pump integrated unit 5, expansion tank 4, diesel tank 3, fuel heater transition bracket 2, and fuel heater unit 1 into a single unit, forming a brand-new, highly integrated thermal management integrated unit.

[0040] In an optional embodiment, three mounting brackets 6 are respectively provided on the left and right sides of the square sheet metal bracket by bolts at intervals, and the mounting brackets are arranged with the openings of the "7" shape facing outwards.

[0041] The fuel heater unit 1 is positioned on the lower left rear side of the square sheet metal bracket via a fuel heater transition bracket 2. The diesel tank 3 is connected to the fuel heater of the fuel heater unit 1 and is positioned above the fuel heater. In this embodiment, the diesel tank 3 is positioned on the rear right side of the square sheet metal bracket via a mounting bracket 6. The expansion tank 4 is positioned above two mounting brackets on the right front side of the square sheet metal bracket, so that the expansion tank 4 is supported by the two mounting brackets and can accommodate expansion tanks of various sizes.

[0042] In one specific embodiment, the fuel heater transition bracket 2 includes a transverse mounting portion 21 and a longitudinal mounting portion 22 connected to each other. The longitudinal mounting portion 22 is a plate-like structure for connecting to the fuel heater unit 1 by bolts, and the transverse mounting portion 21 is a strip-like structure for connecting to a square sheet metal bracket. Preferably, two connecting portions 23 are formed at the upper ends of the transverse mounting portion 21. The two connecting portions 23 are disposed on the left and right sides of the square sheet metal bracket and are installed to the square sheet metal bracket by bolts.

[0043] Preferably, the lower part of the mounting bracket near the fuel heater transition bracket 2 and the connecting part 23 of the fuel heater transition bracket 2 are bolted together and mounted on the square sheet metal bracket.

[0044] The upper part of the mounting bracket has an outward groove, through which the rubber pad 61 is embedded and transitionally fitted with the mounting bracket.

[0045] In this embodiment, the rubber pad 61 has a hollow "dry" - shaped structure, which is convenient for fitting into the notch formed by the upper part of the mounting bracket on the side. To further ensure the strength of the rubber pad 61, a metal bushing and a metal pad are provided inside the rubber pad 61, so that the mounting bracket is arranged between the metal bushing and the metal pad. Rubber B is the main material and can effectively absorb vibration, achieving the effect of vibration reduction.

[0046] The hollow part of the rubber pad 61 is convenient for bolts to pass through it and connect to the frame below.

[0047] The mounting bracket 6 is provided with a rubber pad, and the cross - sectional view of the rubber pad is as Figure 7 , including: metal bushing A, rubber B, and metal pad C. In the whole rubber pad, the metal bushing A is integrally coated inside the rubber pad, which ensures the strength of the whole rubber pad. Rubber B, as the main structure of the whole, can effectively absorb vibration and reduce it. Metal pad C is used at the stress - bearing place of the metal - rubber pad to effectively absorb the bolt torque. Adopting the soft - connection and hard - fitting method can effectively resist adverse factors such as vibration and bump during vehicle operation, ensuring the stability of the system under various working conditions.

[0048] Through this layout structure, the heavy - duty truck pure - electric model can always maintain efficient thermal management under various complex working conditions, thereby effectively improving the energy efficiency and reliability of the whole vehicle, injecting new vitality into the development of new - energy heavy - duty trucks.

[0049] The specific installation process is as follows:

[0050] (1) Fixing of the fuel heater unit:

[0051] The fuel heater unit 1 is firmly fixed to the fuel heater transition bracket 2 through four bolts 7. This design can effectively ensure that it always remains stable during vehicle operation and is not disturbed by factors such as vehicle vibration.

[0052] (2) Installation of the heat pump integration unit:

[0053] The heat pump integration unit 5 is firmly connected to the whole vehicle through bolts 7 and a square sheet - metal bracket. The design of this square sheet - metal bracket fully considers various working conditions during vehicle operation, ensuring that the heat pump integration unit always remains stable and reliable during vehicle operation, effectively avoiding failures caused by factors such as vibration.

[0054] (3) Connection of the fuel heater transition bracket:

[0055] After the fuel heater unit is fixed to the fuel heater transition bracket 2, they form a whole and are tightly connected to the heat pump integration unit 5 through bolts 7. The delicate design of the fuel heater transition bracket fully considers the spatial layout characteristics and connection strength requirements between different components, thus ensuring the stability and reliability of the whole connection structure.

[0056] (4) Installation of expansion tank and diesel tank:

[0057] The expansion tank 4 is connected to the heat pump integrated unit by bolts, and the diesel tank 3 is directly fixed to the mounting bracket 6 by bolts.

[0058] (5) Overall integration:

[0059] All components are interconnected by bolts, forming a complete and efficient integrated thermal management unit. This design not only greatly optimizes the utilization efficiency of vehicle space but also significantly improves the ease of system maintenance, providing strong support for the efficient operation of the vehicle's thermal management system. By forming a unified system unit, the fuel heater, heat pump unit, diesel tank, and expansion tank can be assembled offline, and then the entire vehicle can be assembled as a whole through integrated hoisting, greatly saving production time on the main line.
