[0042] The heating support assembly 210 includes a reinforcing rib 215 . The reinforcing rib 215 is provided on the main support 211 to reinforce the main support 211 .

[0043] like Figures 1 to 5 As shown, in a specific embodiment, the parking heater heating system of a dump truck consists of two major components: a heating channel 100 and a heating device 200. The heating device 200 provides a heat source and is connected to the heating channel 100 to achieve heating of the cargo box.

[0044] The heat source is provided by the heat exhaust holes of the parking heater and the fuel exhaust gas. The heater is fixed to the front panel of the cargo box through a bracket. The heat exhaust pipe and the fuel exhaust gas are connected to the heating channel on the front panel. Heat is conducted through the medium to achieve heating of the cargo box.

[0045] like Figure 4 As shown, the heating device 200 is mainly composed of a heating bracket assembly 210, a parking heater 221, a fuel exhaust pipe 222, a heat exhaust pipe 223, an oil pump 224, a fuel tank 225 and other components; Figure 5As shown, the main support 211 is the main structure, which is designed as a bent L-plate with reinforcement ribs 215 to strengthen the structure. The diesel tank 225 is installed above the main support 211, and a fuel tank protection cover 212 is added to protect the fuel tank 225 from wear and damage. The oil pump 224 is installed below the diesel tank 225, and the oil pump protection cover 213 is fixed to the main support 211 with a C-shaped groove structure to protect the oil pump 224. The oil pipe protection tube 216 is added to the oil pipe position of the main support 211 to protect the oil pipe. The parking heater 221 is installed below the main support 211, and the main support 211 is designed with a notch to facilitate the layout of pipelines such as the oil pipe and the diesel exhaust pipe 222. The heat outlet of the parking heater 221 is connected to the heating channel 100 via a heat exhaust pipe 223, and the exhaust outlet is connected to the heating channel 100 via a fuel exhaust pipe 222, enabling the transfer of the heating medium. This structure eliminates the traditional circulation channel and fully utilizes the heat of the fuel exhaust, improving the efficiency and effectiveness of the cargo box heating. The heating device 200 is connected to the cargo box via a connector 214 in a removable structure, allowing installation of the heating device 200. The addition of this structural protection device improves the overall reliability and service life of the heating device 200, unclutters the piping route, prevents exposed parts, and significantly enhances its aesthetics and overall integrity.

[0046] like Figure 1 and Figure 2 As shown, the heat exhaust pipe 223 of the parking heater 221 is connected to the heat exhaust pipe sleeve 112 fixed on the front plate 102, and the fuel exhaust pipe 222 is connected to the fuel exhaust pipe sleeve 111 fixed on the front plate 102, thereby realizing the communication between the heating device 200 and the heating channel 100. The heating medium enters the front corner panel 113 of the cargo box through two pipe sleeves, is divided into the left and right sides, and enters the local heating channel formed by the side wing panel 115 and the side wing panel lower plug 114 through the smoke hole of the side panel 101. The local heating channel extends to the rear end of the cargo box and is discharged through the exhaust pipe 117 to realize the circulation of the heating medium; insulation material 116 is designed and installed on the side wing panel lower plug 114 inside the heating channel 100 for insulation to prevent heat loss. This heating channel 100 cancels the previous circulation channel structure, realizes rapid circulation of the heating medium, and improves heating efficiency; and makes full use of the high-calorie fuel exhaust of the parking heater 221, adds insulation material 116 to the heating channel 100 for insulation, so as to further improve the heating effect.

[0047] The heating system uses a parking heater to provide the heat source. The hot air outlet and combustion exhaust gas are connected to the heating channel and circulate to the air outlet at the rear of the cargo box for heating. The heating channel adopts a front corner panel and side wing panel heating structure, and is designed to add insulation materials. The medium flow type is higher, the heat loss is small, and the heating efficiency is more significant; and the high-temperature fuel exhaust is fully utilized to improve the heating effect; the heater bracket simplifies the weight reduction design, and adds fuel tank protection cover, oil pipe protection pipe and other parts to improve structural reliability.

[0048] The beneficial effects of this embodiment are as follows.

[0049] 1. The circulating heating channel is cancelled and a U-shaped bucket heating straight channel is adopted. The parking heater exhaust port, heating channel and cargo box rear air outlet are connected. The circulating structure is cancelled, the medium flowability is improved, and the heating efficiency is high.

[0050] 2. The heating channel adopts the heating structure of front angle plate and side wing plate, and adds thermal insulation material for insulation. The channel is straight without twists and turns, with small heat loss and high heating effect.

[0051] 3. The parking heater recycles the high-temperature fuel exhaust gas and passes it directly into the heating channel to improve the heating temperature and heating effect.

[0052] 4. The heating device mounting bracket simplifies the weight reduction design, adds a fuel tank protection cover and fuel pipe protection tube, reduces the risk of damage to wearing parts, and improves the overall reliability of the heating system.

[0053] 5. Additional protective devices are added to the exterior, and the overall assembly structure is adopted, which makes installation and maintenance more portable. A fuel tank protection cover is added to the heater fuel tank to protect the fuel tank and prevent oil leakage; a fuel pipe protection steel pipe is added to the fuel pipeline to protect the fuel pipe and prevent it from wear; the fuel tank, pipeline and other components are not completely exposed, and the appearance is more beautiful and less susceptible to damage.

[0054] 6. The heater bracket has an integrated bending structure, eliminating welding, meeting the requirements of multi-component connection, simplifying the heating channel structure, and improving production portability; each component can be assembled and connected in a detachable manner, which makes installation and disassembly simple, and maintenance and replacement more portable.
