[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention is divided into two parts, namely, a cabin and a radiator cabin, by a shell. The unit is installed in the cabin, and the radiator assembly is installed in the radiator cabin. The two cabins are separated by a partition so that the heat generated by the radiator assembly and the unit will not flow between the two cabins, and the heat is not easy to affect each other. On this basis, the heated gas in the cabin is discharged by the cabin fan assembly. Specifically, the internal gas is driven along the inclined shell to the cabin exhaust port by the cabin fan. The cabin fan is installed obliquely and is installed on the side top of the cabin. The installation position and installation angle can guide and drive the gas in the entire cabin to converge there during the exhaust process, and can also drive the wind at the silencer air duct to move inward, thereby improving the heat dissipation effect. The heat generated at the radiator assembly is pulled upward and discharged by the radiator fan. The heat dissipation fan exhausts and dissipates the heat in the radiator cabin. The gas in the cabin is discharged from the exhaust port. The radiator fan at the discharge position can drive the hot air upward and discharge it together, thereby enhancing the exhaust efficiency and traction effect during the cabin exhaust process.

[0018] (2) The silencer duct serves to allow external air to enter the interior, and when the air enters the interior, the noise generated by the air entering is reduced by the silencer cotton on the inner wall. The duct louvers are located at the ends of the silencer duct. When the duct louvers are closed, they serve to block and seal the silencer duct. When they are opened, the air can enter the interior for heat dissipation. The front and rear ends of the radiator compartment are provided with air inlet louvers. During the heat dissipation process, opening the air inlet louvers allows external air to enter the radiator compartment, thereby increasing the air intake there and accelerating the heat dissipation effect there.

[0019] (3) The water-cooled radiator and the intercooled radiator are connected to the engine through the radiator inlet pipe and the radiator outlet pipe, and are used to cool down the engine. The two sets of radiators can effectively improve the cooling effect on the engine, avoid the engine temperature being too high, and prevent the situation where the engine cannot operate efficiently for a long time, and ensure that the engine is in an appropriate temperature range. In addition, when the air inlet shutters are opened, the water-cooled radiator and the intercooled radiator in the radiator compartment can be affected by the external air and cooled. In combination with the radiator fan above, the cooling efficiency of the radiator itself is effectively improved, ensuring the normal heat dissipation cycle process between the engine and the radiator.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, an embodiment provided by the present invention: a high-efficiency and low-emission methanol generator, comprising a shell 1, wherein a cabin 2 and a radiator cabin 6 are arranged on the left and right sides of the interior of the shell 1, a partition 602 is arranged between the cabin 2 and the radiator cabin 6, a unit 3 is installed inside the cabin 2, a radiator assembly 10 is installed inside the radiator cabin 6, the unit 3 and the radiator assembly 10 are connected by a pipeline, a cabin fan assembly 8 is installed on the top of the cabin 2, a radiator fan 7 is installed on the top of the radiator cabin 6, the cabin fan assembly 8 comprises an oblique shell 801, a cabin fan 802 is installed inside the oblique shell 801, the cabin fan 802 is installed at an angle of 35°-45°, a cabin exhaust port 803 is installed on one side of the oblique shell 801, and one end of the cabin exhaust port 803 extends to the radiator fan 7; the shell 1 is divided into two parts, the cabin 2 and the radiator cabin 6, the unit 3 is installed in the cabin 2, the radiator assembly 10 is installed in the radiator cabin 6, and the two cabins are separated by a partition 6 02 separation, so that the heat generated by the radiator assembly 10 and the unit 3 will not flow between the two compartments, and the heat is not easy to affect each other. On this basis, the heated air in the cabin 2 is discharged through the cabin fan assembly 8. Specifically, the internal air is driven by the cabin fan 802 along the inclined shell 801 to the cabin exhaust port 803. The cabin fan 802 is installed obliquely and is installed on the side top of the cabin. During the exhaust process, this installation position and installation angle can guide and drive the air in the entire cabin to converge there, and at the same time, can drive the wind at the silencer duct 201 to move inward, thereby improving the heat dissipation effect. The heat generated at the radiator assembly 10 is pulled upward and discharged by the radiator fan 7. The radiator fan 7 exhausts and dissipates heat to the radiator compartment 6, and the air in the cabin 2 is discharged from the cabin exhaust port 803. The radiator fan 7 at this discharge position can drive the hot air upward and discharge it, thereby enhancing the exhaust efficiency and traction effect during the exhaust process of the cabin 2.

[0031] In addition, a fan flange 701 is provided at the lower bottom of the radiator fan 7, and the fan flange 701 is fixed to the upper top of the shell 1 by bolts. The contact surface between the fan flange 701 and the shell 1 is provided with EVA cotton 702, and the EVA cotton 702 is in a circular ring shape; the radiator fan 7 will generate vibrations during the exhaust process, and the vibration is easily worn and generates noise due to the contact between the fan flange 701 and the shell 1. The EVA cotton 702 has good wear resistance, pressure resistance, shock absorption and anti-slip properties. Through the setting of the EVA cotton 702, the fan flange 701 can be avoided from direct contact with the shell 1, thereby reducing the noise there and improving the safety of the fan there.

[0032] See also Figure 2 、 Figure 3The ends of the cabin 2 and the radiator cabin 6 are both equipped with a second hatch 204, and a silencer duct 201 is installed near the second hatch 204 inside the cabin 2. The inner wall of the silencer duct 201 is provided with silencer cotton. An end of the silencer duct 201 near the second hatch 204 is equipped with an air duct louver 202, and the front and rear ends of the radiator cabin 6 are both equipped with air inlet louvers 601; the silencer duct 201 serves to allow external air to enter the interior, and when the air enters the interior, it is discharged through the inner duct. The silencer cotton on the wall reduces the noise generated by the entry of gas. The duct louver 202 is located at the end of the silencer duct 201. When the duct louver 202 is closed, it has the effect of blocking and closing the silencer duct 201. When it is opened, the gas can enter the interior for heat dissipation. The front and rear ends of the radiator compartment 6 are provided with air inlet louvers 601. During the heat dissipation process, opening the air inlet louvers 601 can allow external gas to enter the radiator compartment 6, thereby increasing the air intake there and accelerating the heat dissipation effect there.

[0033] See also Figure 3 、 Figure 6 、 Figure 7 The unit 3 includes an engine 301, a generator 302 is installed on one side of the engine 301, the engine 301 includes a body assembly 3011, an oil pan 3012 is installed at the bottom of the body assembly 3011, a crankshaft assembly 3013 is installed at one end of the body assembly 3011, an intake manifold 3015 and an exhaust manifold 3016 for air intake and exhaust are installed on the outer wall of the engine 301, an exhaust pipe port 3017 is installed above the engine 301, a plurality of shock-absorbing pads 3014 are installed on the outer wall of the body assembly 3011, and the crankshaft assembly 3013 is installed on the outer wall of the engine 3011. Its function is to convert the reciprocating linear motion of the piston into its own rotational motion, thereby outputting power to the outside. The main function of the intake manifold 3015 is to evenly distribute air and fuel to each cylinder of the internal combustion engine. When the engine 301 inhales air, the intake manifold 3015 ensures a continuous and controllable air supply to optimize the combustion process. The exhaust manifold 3016 is connected to the cylinder block of the engine 301. Its main function is to collect the exhaust gas from each cylinder and guide it into the exhaust manifold. The setting of the shock-absorbing foot pad 3014 is used to improve the shock absorption and stability of the body assembly 3011.

[0034] See also Figure 3 、 Figure 5The radiator assembly 10 includes a water-cooled radiator 1001 and an intercooled radiator 1002. The water-cooled radiator 1001 and the intercooled radiator 1002 are respectively located on both sides of the interior of the radiator compartment 6. A radiator inlet pipe 1003 is installed above the water-cooled radiator 1001 and the intercooled radiator 1002. A radiator outlet pipe 1004 is installed below the water-cooled radiator 1001 and the intercooled radiator 1002. One end of the radiator inlet pipe 1003 and the radiator outlet pipe 1004 are both connected to the pipeline at the engine 301. A methanol tank 4 is also installed inside the radiator compartment 6. A methanol water jacket heater 5 is installed on one side of the methanol tank 4. The water-cooled radiator 1001 and the intercooled radiator 1002 are connected to the engine 301 through the radiator. Inlet pipe 1003 and radiator outlet pipe 1004 are connected to engine 301 to cool and dissipate heat from engine 301. The two radiator groups effectively improve the cooling effect on engine 301, preventing it from overheating and preventing it from operating efficiently for a long time. This ensures that engine 301 remains within an appropriate temperature range. Furthermore, when air inlet louvers 601 are open, both the water-cooled radiator 1001 and the intercooler radiator 1002 within radiator compartment 6 are cooled by the external air. This, combined with the radiator fan 7 above, effectively improves the cooling efficiency of the radiators themselves, ensuring the proper heat dissipation cycle between engine 301 and the radiator. Methanol tank 4 stores methanol, and methanol water jacket heater 5 preheats the antifreeze when the ambient temperature is below 16°C.

[0035] See also Figure 2 、 Figure 3 A muffler 9 is installed on the upper top of the cabin 2. A smoke inlet pipe 902 is installed at one end of the muffler 9. The smoke inlet pipe 902 is connected to the exhaust pipe port 3017 through a flange. An exhaust port 901 is installed at the other end of the muffler 9. The engine 301 discharges smoke from the exhaust pipe port 3017. The smoke flows into the muffler 9 along the smoke inlet pipe 902, so that the smoke is silenced in the muffler 9, which reduces the noise generated during the exhaust process. Finally, the silenced gas is discharged to the outside from the exhaust port 901.

[0036] See also Figure 1 、 Figure 2 、 Figure 8A control panel 205 is provided on the second door 204 of the engine room 2, and an audible and visual alarm 206 is installed above the control panel 205. First doors 203 are installed at both the front and rear ends of the engine room 2, and a power distribution cabinet 207 is installed on one side of the first door 203. The power distribution cabinet 207 is used to place and install the components and corresponding wiring harnesses required for the engine 301 and the radiator assembly 10. An internal temperature sensor (not shown in the figure) is used to monitor temperature changes and feedback them to the control panel 205. When the temperature exceeds the temperature range, the control panel 205 feedbacks to the audible and visual alarm 206, causing the audible and visual alarm 206 to sound an audible and visual alarm, which serves to alert the surrounding area and prevent the internal temperature from being too high for a long time, which may cause damage to the internal components. The first door 203 is used to facilitate users to open the door to inspect the unit 3 in the engine room 2. The power distribution cabinet 207 can be opened and inspected directly at the rear of the shell 1. The radiator compartment 6 can be inspected internally through the second door 204.
