[0024] The present invention is further described below in conjunction with embodiments, which are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in the field without creative work are all within the scope of protection of the present invention.

[0025] Embodiment 1:

[0026] like Figure 1-2 As shown, a vehicle-mounted multi-stage pressurized exhaust system includes: a heat dissipation fan, an exhaust pipe, and a pressurized fan. A plurality of the heat dissipation fans are installed on the side wall of the vehicle-mounted system equipment cabinet; the heat dissipation fan is designed to be installed at the air outlet of the system equipment cabinet. According to the shape of the exhaust pipe and the limitation of the space inside the vehicle, the heat dissipation fan must be installed at an angle to avoid reflection and eddy current formed by the heat flow. The number and size of the heat dissipation fans are determined by the total power consumption of the system equipment. The heat dissipation fan is detachable and replaceable.

[0027] In order to ensure that the heat consumption of the system equipment is smoothly discharged out of the vehicle body, it must pass through an exhaust duct. The air inlet end of the exhaust duct is installed on the side wall of the vehicle-mounted system equipment cabinet and is connected to the air outlet end of the heat dissipation fan; the air outlet end of the exhaust duct is arranged inside the vehicle wall and is connected to the outside world; the air outlet end of the exhaust duct is lower than the air inlet end of the exhaust duct, so that rainwater from the outside will not flow back into the vehicle-mounted system equipment cabinet.

[0028] There are several bends between the air outlet end of the exhaust duct and the air inlet end of the exhaust duct to adapt to the space inside the car. When modifying the limited space inside the car, the exhaust duct will not be straight, and the exhaust duct will not be very short. The heat flow will be resisted in the exhaust duct. In the limited space inside the car, the design of the exhaust duct must ensure the shortest distance and the least corners, so as to reduce the resistance of the heat flow. Therefore, it is necessary to design a booster fan, and there are multiple boosters. The booster fan is provided in the car wall near the air outlet end of the exhaust duct and at the bend of the exhaust duct. The installation position of the booster fan is designed to be near the corner of the exhaust duct. At the same time, a booster fan must be designed and installed at the outlet of the car wall to ensure that the heat flow in the exhaust duct is effectively discharged outside the car body. At the same time, the booster fan is detachable and replaceable.

[0029] Preferably, the angle between the installation position of the heat dissipation fan and the side wall of the vehicle-mounted system equipment cabinet is 100°-110°, so as to minimize the reflection and eddy current formed by the heat flow.

[0030] An air outlet is designed on the side wall of the modified vehicle, and a maintenance window is designed outside the air outlet. Shutters are set on the maintenance window wall, so that water will not flow directly into the air duct when the modified vehicle is in rainy days or when washing the car; a one-way airflow valve is designed inside the air outlet. When the fan in the air duct is working, the valve opens and the heat flow is discharged outside the vehicle. When the fan stops working, the valve closes to block some dust and splashing water; a filter is designed and installed on the inside of the valve, which prevents dust from entering the air duct and equipment cabinet when the one-way airflow valve is open during driving; a booster fan is designed and installed on the inside of the filter to ensure that the heat flow in the air duct is effectively and quickly discharged from the body. At the same time, the maintenance window, one-way airflow valve, filter grid, and heat dissipation fan are all removable and replaceable.

[0031] It should be noted here that the one-way airflow valve is a number of baffles arranged in the air outlet, which together match the shape of the air outlet. Each baffle is correspondingly connected to the rotating shaft set at the air outlet. When the boost fan and the cooling fan are not working, they naturally fall under the action of gravity, closing the air outlet and blocking some dust and splashing water. When the boost fan and the cooling fan are working, they will open under the action of wind pressure to ensure that the heat flow in the air duct is effectively and quickly discharged out of the vehicle body.

[0032] The present invention also provides a vehicle-mounted multi-stage pressurization and exhaust method, comprising the following steps:

[0033] Step 1: Install a cooling fan on the side wall of the vehicle system equipment cabinet;

[0034] Step 2: Open an exhaust vent on the vehicle wall;

[0035] Step 3: Use an exhaust pipe to connect the air outlet of the heat dissipation fan to the exhaust port on the vehicle wall; the air outlet of the exhaust pipe is lower than the air inlet of the exhaust pipe, and a plurality of bends are provided between the air outlet of the exhaust pipe and the air inlet of the exhaust pipe to adapt to the space in the vehicle;

[0036] Step 4: A booster fan is provided in the vehicle wall near the exhaust port and at the bend of the exhaust pipe.

[0037] The air inlet end of the exhaust pipe is arranged close to the side wall of the vehicle system equipment cabinet, and the angle between the installation position of the heat dissipation fan and the side wall of the vehicle system equipment cabinet is an obtuse angle. The angle between the installation position of the heat dissipation fan and the side wall of the vehicle system equipment cabinet is 100°-110°. This can minimize the reflection and eddy current formed by the heat flow.

[0038] The on-board multi-stage pressurized exhaust system effectively removes the heat generated by the operation of system equipment in the modified vehicle out of the vehicle, ensuring stable and reliable operation of the equipment; reducing the impact of equipment heat consumption on the vehicle's air conditioning cooling effect; and reducing the impact of harmful gases generated when the temperature rises too high during equipment operation on the health of passengers.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
