Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The cooling component includes a water tank chamber 6 disposed inside the box body 1. Two water tank chambers 6 are provided. The two water tank chambers 6 are symmetrically distributed on the front and rear sides of the methanol tank 2. Air inlets 7 are evenly opened on the inner walls of the front and rear sides of the box body 1. A fan 29 is installed on the top of the box body 1.

[0035] A circulation pump 8 is installed inside the box body 1, and connecting pipes 9 are installed at both ends of the circulation pump 8. Atomizing nozzles 10 are evenly installed on the outer wall of one of the connecting pipes 9. The atomizing nozzle 10 is arranged above the inside of the water tank chamber 6, and the other connecting pipe 9 is embedded in the bottom of the water tank chamber 6.

[0036] The device takes in air from both the front and rear sides of the box 1, which can ensure the air volume required for the full-load operation of the engine 3;

[0037] Vent holes corresponding to the air inlets 7 are formed on both sides of the top of the water tank chamber 6.

[0038] When the fan 29 is working, the water tank chamber 6 generates negative pressure, and outdoor air is sucked into the water tank chamber 6 through the air inlets 7, and then is discharged into the box body 1 to cool the device in the box body 1 and then is discharged, thereby completing the cooling.

[0039] At the same time, the circulating pump 8 is started, and the water source in the water tank chamber 6 is connected through the connecting pipe 9 and is atomized and discharged through the atomizing nozzle 10. When outdoor gas passes through the water, the water has a high specific heat capacity and can absorb a large amount of heat in the gas, so that the temperature of the gas is significantly reduced.

[0044] As shown in Figure 2 and Figure 7 , the flow guide plate 12 is protrusively arranged away from the water tank chamber 6.

[0045] The low-temperature gas is blown downward to increase the contact surface with the device in the box body 1, thereby improving the heat dissipation effect.

[0046] As shown in Figure 2 and Figure 7 , the sidewall of the flow guide plate 12 is provided with a first moisture absorbing plate 14.

[0047] The first moisture absorption plate 14 is provided as a silica gel plate with a large number of micro-pores to form a large adsorption surface to capture water in the air by physical adsorption and to adsorb moisture in the low-temperature gas passing through the water to reduce the moisture in the low-temperature gas as much as possible to avoid the influence of the moisture on heat dissipation and to protect the power generation device.

These impurities will gradually block the pores of the filter screen 11 to cause the filtration resistance to increase and the flow to decrease. The reciprocally moving brush plate 27 removes the blockage on the surface of the filter screen 11 by mechanical friction to keep the pores unblocked to maintain stable filtration flow and efficiency.
