[0020] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] This utility model provides a cold start heating device for a power system, such as... Figure 1 The powertrain cold start heating device of one embodiment is used to heat the fuel and coolant of the engine 12. The powertrain cold start heating device includes a heater 11, a coolant circulation loop 15, a fuel circulation loop 16, an oil intake pipe 17, and an electric heating component 20. The coolant circulation loop 15 is arranged between the heater 11 and the engine 12 to circulate the coolant of the engine 12 between the heater 11 and the engine 12. The oil intake pipe 17 is arranged between the heater 11 and the fuel tank 13 to supply fuel to the heater 11. The heater 11 heats the coolant of the engine 12 passing through the heater 11 by burning fuel, thereby shortening the vehicle warm-up time. The fuel circulation loop 16 is arranged between the engine 12 and the fuel tank 13 to supply fuel to the engine 12. The electric heating component 20 is arranged inside the fuel tank 13 and / or on the fuel circulation loop 16 to heat the fuel.

[0022] In this embodiment, electric heating components 20 are arranged both inside the fuel tank 13 and on the fuel circulation loop 16, which improves the heating effect and efficiency of the fuel. However, this is not the only embodiment. In other embodiments, it is also feasible to arrange electric heating components 20 only on the fuel circulation loop 16 (i.e., no electric heating components 20 are arranged inside the fuel tank 13), or to arrange electric heating components 20 only inside the fuel tank 13 (i.e., no electric heating components 20 are arranged on the fuel circulation loop 16). This can also achieve the purpose of heating the fuel before or during vehicle startup.

[0023] In the power system cold start heating device and vehicle of this utility model, the heater 11 transfers the heat generated by the combustion of fuel drawn from the fuel tank 13 to the coolant of the engine 12, and then the engine 12 is preheated through the circulation of the coolant. There is no need to heat the coolant through the exhaust gas of the engine 12. The engine 12 can be preheated before starting, so that the engine 12 can be started normally even in the extreme ambient temperature of extremely cold regions.

[0024] It should be noted that coolant is a substance well known to those skilled in the art, and will not be described in detail here.

[0025] In this embodiment, the coolant circulation loop 15 includes an inlet pipe 151 and an outlet pipe 152. The two ends of the inlet pipe 151 are connected to the heater 11 and the engine 12, respectively, and the two ends of the outlet pipe 152 are connected to the heater 11 and the engine 12, respectively.

[0026] Specifically, the heater 11 includes an inlet and an outlet. The inlet is connected to the coolant intake port on the engine 12 via an inlet pipe 151, and the outlet is connected to the coolant return port on the engine 12 via an outlet pipe 152. Coolant enters the heater 11 from the coolant intake port on the engine 12 through the inlet pipe 151 for heating. Fuel is drawn from the fuel tank 13 by the oil intake pipe 17 under the action of the electromagnetic pump 14 and introduced into the heater 11. The heater 11 heats the coolant passing through it by burning the fuel. The heated coolant flows into the outlet pipe 152 through the outlet and then into the engine 12. The circulating coolant heats the engine 12 body and preheats the engine 12.

[0027] In this embodiment, a first maintenance valve 18 is provided on the inlet pipe 151, and a second maintenance valve 19 is provided on the outlet pipe 152. Both the first maintenance valve 18 and the second maintenance valve 19 are used for maintenance and inspection of the coolant circulation loop 15. The first maintenance valve 18 and the second maintenance valve 19 enable maintenance of the cooling system when needed, ensuring the reliability and safety of the system.

[0028] In this embodiment, the fuel circulation loop 16 includes an inlet pipe 161 and a return pipe 162. The two ends of the inlet pipe 161 are connected to the engine 12 and the fuel tank 13, respectively, and the two ends of the return pipe 162 are connected to the engine 12 and the fuel tank 13, respectively.

[0029] Specifically, the fuel tank 13 is connected to the fuel inlet of the engine 12 via the fuel inlet pipe 161 and to the fuel return port of the engine 12 via the fuel return pipe 162, thereby supplying fuel to the engine 12.

[0030] In this embodiment, as Figure 2-4 As shown, a fuel tank 13 has an internal fuel suction pipe 163. The top end of the fuel suction pipe 163 is connected to one end of the fuel inlet pipe 161, allowing fuel inside the fuel tank 13 to be discharged through the fuel suction pipe 163. The bottom end of the fuel suction pipe 163 extends towards the bottom of the fuel tank 13, close to its bottom surface. Fuel in the fuel tank 13 flows out from the fuel suction pipe 163 and into the fuel inlet pipe 161, then flows into the engine 12 to supply fuel to the engine 12.

[0031] In this embodiment, the electric heating assembly 20 includes a fuel line heating assembly 21, which is disposed on the fuel inlet pipe 161. The fuel line heating assembly 21 is powered by a battery to heat the fuel in the fuel inlet pipe 161. In this embodiment, the fuel line heating assembly 21 is installed at the fuel inlet of the fuel inlet pipe 161 (near the fuel tank 13).

[0032] Furthermore, the fuel line heating assembly 21 includes a heating wire inserted inside the fuel inlet pipe 161. The heating wire is powered by a battery to heat the fuel inside the fuel inlet pipe 161.

[0033] Specifically, the fuel line heating assembly 21 includes a main body and a heating wire extending from the main body. One end of the main body is mounted on the fuel tank 13 and connected to the fuel suction pipe 163, while the other end is connected to the fuel inlet of the fuel inlet pipe 161. Fuel flows from the fuel tank 13, sequentially through the fuel suction pipe 163, the main body of the fuel line heating assembly 21, and the fuel inlet pipe 161 into the engine 12. The heating wire is inserted inside the fuel inlet pipe and is powered by a battery to heat the fuel in the fuel inlet pipe 161. In addition to the heating wire, the main body of the fuel line heating assembly may also include a temperature sensor, a control unit, heat insulation material, safety devices, mounting brackets or clamps, connecting cables, and seals. The heating assembly comprises several components: a temperature sensor to monitor fuel temperature and ensure it is heated to the appropriate operating temperature, preventing overheating or failure to reach the required temperature; a control unit to adjust the heating power of the heating element based on feedback from the temperature sensor, achieving precise temperature control; insulation material surrounding the heating element to reduce heat loss and improve heating efficiency; safety devices such as fuses or thermal switches to cut off power in case of overheating or other abnormalities, preventing damage or accidents; mounting brackets or clamps to secure the heating assembly in the correct position, ensuring stable operation; connecting cables to connect the heating assembly to a battery or other power source; and seals to ensure a tight seal between the fuel line and the heating element, preventing fuel leakage.

[0034] In this embodiment, the oil extraction pipe 17 is connected to the oil extraction port of the fuel tank 13. The oil extraction port is located near the end of the oil suction pipe 163 that is not connected to the oil inlet pipe 161, which facilitates oil extraction by the oil extraction pipe 17. The oil extraction pipe 17 is connected to the fuel tank 13 by means of a bamboo nut and a hollow bolt.

[0035] In another embodiment, the fuel intake pipe 17 may be equipped with a fuel pipe heating function, preheating the fuel drawn from the fuel tank 13 before it is delivered to the heater 11. Preheated fuel is easier to atomize, meaning it can mix more thoroughly with air, thereby improving combustion efficiency. Fuel is drawn from the fuel tank 13 into the fuel intake pipe 17 by the electromagnetic pump 14. During its flow within the fuel intake pipe 17, the fuel is heated by its own heating function. The preheated fuel then enters the heater 11 for combustion to heat the coolant passing through the heater 11.

[0036] In this embodiment, the electric heating assembly 20 further includes heating rods 22, which are disposed inside the fuel tank 13 and near the bottom of the fuel tank 13, and are positioned near the bottom end of the fuel suction pipe 163. Multiple heating rods 22 are arranged around and distributed near the bottom end of the fuel suction pipe 163 to heat the fuel near the bottom port of the fuel suction pipe 163.

[0037] Specifically, in this embodiment there are two heating rods 22, which are distributed on both sides of the bottom end of the oil suction pipe 163 to heat the fuel near the port of the oil suction pipe 163, so as to prevent the fuel from waxing and thus prevent the engine 12 from working normally.

[0038] In this embodiment, the power system cold start heating device also includes an electromagnetic pump 14, which is located on the oil intake pipe 17 and is used to transport fuel from the fuel tank to the heater 11 for combustion.

[0039] In this embodiment, the fuel tank 13 is also equipped with a liquid level and temperature gauge, an air filter and a fuel level sensor. The liquid level and temperature gauge is used to detect the remaining amount of fuel in the fuel tank 13 and the temperature of the fuel. The air filter is used to filter the air entering the fuel tank 13. The fuel level sensor is used to monitor the amount of fuel in the fuel tank 13 in real time and provide accurate information about the remaining amount of fuel.

[0040] This utility model also provides a vehicle, including the power system cold start heating device as described above. Specifically, the vehicle in this embodiment is a mobile crusher.

[0041] In extremely cold regions like Russia, where temperatures can drop to -40 degrees Celsius, the crusher's power system cannot start normally without cold start preheating. Current technology uses engine exhaust heating, which only begins heating after the engine is running; without engine preheating, the crusher cannot operate normally. Furthermore, existing technology lacks fuel heating and fuel line heating components. In extremely cold conditions, the fuel will wax, making it difficult to flow and affecting the power system's operation.

[0042] 1) This utility model uses a storage battery to power the heating rod 22 and the fuel pipe heating assembly 21, thereby achieving fuel and fuel pipe heating and preventing fuel waxing.

[0043] 2) The superheater 11 of this utility model transfers the heat generated by the combustion of fuel drawn from the fuel tank 13 to the coolant in the engine 12. Through the circulation of the coolant, the engine 12 is preheated, eliminating the need to heat the coolant with the exhaust gas of the engine 12, thus enabling preheating of the engine before starting.
