Description

Technical field:

[0001] The invention relates to the field of ventilation systems, and in particular to a controllable heat dissipation ventilation system of a self-righting amphibious boat and a control method thereof. Background technology:

[0002] Amphibious boats are vehicles that have both land and water driving capabilities. The design requirements for the power system during driving are very different. The mechanical efficiency of the traditional automobile internal combustion engine power system is about 40%, and the remaining 60% needs to be dissipated through heat exchange. 17% of this heat energy is dissipated through radiator heat exchange, 10% through intercooler heat exchange, 29% through the exhaust system, and 5% through engine surface heat radiation. In the design of the heat dissipation system of land vehicles, a semi-wrapped method is usually adopted. The front of the vehicle is directly facing the wind. The air intake grille is used to intake air, and the bottom is hollowed out to allow the outside air to better take away the heat generated by the engine; the latter needs to ensure the sealing of the bottom of the boat when driving in water. Generally, the air intake system and the exhaust system are arranged at a higher position as much as possible to prevent splashing water from entering the power system and causing damage to the engine. It is necessary to consider the heat radiation on the engine surface and the surface heat radiation of the part wrapped in the boat body. At the same time, as a self-righting amphibious boat, it needs to have the ability to resist roll and right itself under certain wind and waves. During this process, lake water can easily flow into the air intake system from both sides, causing damage to the power system. Therefore, it is necessary to design a controllable heat dissipation and ventilation system for the self-righting amphibious boat, which can not only meet the heat dissipation requirements of land driving, but also meet the heat dissipation design requirements of the boat cabin when driving on water.

Based on the most advanced structure, the exhaust device 2 and the air intake device 5 are used for cooling the air intake and exhaust, and the air intake and exhaust here are mainly for the engine 6, and water cooling is configured to cool the engine 6, which helps to solve the technical problem of the lack of a heat dissipation and ventilation system for an amphibious boat in the prior art.

[0084] In one embodiment, the present invention further provides a control method for a controllable heat dissipation and ventilation system of a self-righting amphibious craft. Based on the controllable heat dissipation and ventilation system of the self-righting amphibious craft, the control method includes:

[0085] Acquire attitude parameters and temperature parameters according to the attitude sensor and the temperature sensor;

[0086] Intake and exhaust are adjusted according to the posture parameter and the temperature parameter.

[0087] In addition, the radiator is placed in the front compartment of the hull, connected to the engine in the rear compartment through a cooling water pipe. An air intake device is provided on the left side of the hull to introduce outside air into the rear compartment of the hull. Part of it flows into the air filter and enters the engine through the air intake guide fan, and is discharged from the hull through the exhaust pipe after combustion; part of it takes away the radiant heat energy generated by the engine through the first heat dissipation guide fan and is discharged from the hull through the exhaust guide fan; part of it flows into the tail area of ​​the rear compartment of the hull through the second heat dissipation guide fan and is discharged from the hull through the tail air outlet. The self-righting device is installed on the top of the hull.

[0088] When the boat rolls to a large extent, it is immersed in water to generate buoyancy, which inhibits the boat from rolling to the side.

[0089] The closed cabin of the hull is divided into a front cabin and a rear cabin. The front cabin is provided with a radiator air inlet. After the cold air enters, it flows through the radiator to take away the heat and is discharged out of the hull through the radiator air outlet at the wheel cover. The front left side of the rear cabin is an air intake device, and the right side and the tail are exhaust devices.

[0090] The air inlet of the air inlet device is provided with an air inlet baffle which can be opened and closed actively, and the tail part is divided into an engine air inlet manifold, a heat radiation manifold and a ventilation manifold;

[0091] The exhaust device is equipped with an exhaust pipe, a portion of which passes through the exhaust device and then passes through the other end to the exhaust pipe heat shield, and the muffler is installed in the exhaust pipe heat shield. The joints are all sealed;

[0092] A second heat dissipation guide fan is installed at the tail of the engine intake manifold to provide air for the engine to burn and work;

[0093] A first heat dissipation guide fan is installed at the tail end of the heat radiation manifold to blow the radiant heat on the engine surface to the right side. A forced exhaust manifold is provided on the right exhaust device to suck in hotter air through the exhaust guide fan. The hot air flows through the hotter exhaust pipe to cool it down and reduce the heat energy radiation of the exhaust pipe in the rear compartment of the boat. Finally, the hot air is discharged out of the boat through the exhaust water baffle.

[0094] An air intake guide fan is installed at the rear of the ventilation manifold to guide the cold air so that the cold air flows through the rear compartment of the hull and is discharged through the air outlet at the rear of the hull.

[0095] The air intake guide fan, the first heat dissipation guide fan, the second heat dissipation guide fan, and the exhaust guide fan can all adjust the rotation speed to control the air flow;

[0096] The air intake baffle shown is normally open to meet the air intake needs of the engine and the rear compartment of the boat. When the body inclination sensor detects that the inclination angle is greater than 30°, the air intake can be actively closed and the engine power can be reduced to ensure the stability of the vehicle.

[0097] The exhaust water baffle is of normally closed type. When the wind and waves are strong or the body inclination sensor detects an angle greater than 30°, the exhaust guide fan can be actively closed. At this time, there is no wind pressure in the forced exhaust manifold, and the exhaust water baffle is in a closed state, which can prevent lake water from entering the rear compartment of the boat. When the wind and waves are weak or the body inclination sensor detects an angle less than 30°, the exhaust guide fan is opened again. At this time, the wind pressure in the forced exhaust manifold can open the exhaust water baffle, and discharge the radiant heat energy of the engine out of the boat.

[0098] In this embodiment, a specific implementation method of a control method for a controllable heat dissipation and ventilation system of a self-righting amphibious craft is provided. The working modes of the self-righting amphibious craft are divided into land driving and water driving. When the self-righting amphibious craft is driving on land, the engine is in a low-power power generation state, and the driving force is provided by the hub motor. The engine's air intake demand is relatively small. At this time, the speed of the air intake guide fan is moderate, and the external cold air mainly takes away the heat in the cabin through the first heat dissipation and heat conduction fan 8, the second heat dissipation and heat conduction fan 9 and the exhaust guide fan, thereby ensuring the engine's air intake and the engine's operating temperature. When the temperature sensor detects a change in the cabin temperature, the guide fan speed in the higher temperature area is adjusted to make the local temperature reach a balanced operating temperature;

[0099] When the self-righting amphibious boat is traveling on the water, the engine needs to provide high power output to ensure the speed on the water. At this time, the speed of the air intake guide fan is adjusted with the engine power to ensure the air intake of the engine. A part of the external cold air takes away the heat in the cabin through the first heat dissipation fan 8, the second heat dissipation fan 9 and the exhaust guide fan to ensure the working temperature of the engine. When the temperature sensor detects the temperature change in the cabin, the speed of the guide fan in the higher temperature area is adjusted to make the local temperature reach the balanced working temperature;

[0100] When the wind and waves are strong or the body inclination sensor detects an angle greater than 30°, the air intake water baffle and exhaust guide fan can be actively closed. At this time, there is no wind pressure in the forced exhaust manifold, and the exhaust water baffle is in a closed state, which can prevent lake water from entering the rear compartment of the boat. At this time, the self-righting device is immersed in the water to generate buoyancy and suppress the tilt of the boat. When the wind and waves are small or the body inclination sensor detects an angle less than 30°, the air intake water baffle and exhaust guide fan are opened again. At this time, the wind pressure in the forced exhaust manifold can open the exhaust water baffle and discharge the radiant heat energy of the engine out of the boat. All systems are in normal working condition.

[0101] Beneficial effects:

[0102] (1) Solve the ventilation and heat dissipation problems of self-righting amphibious boats when traveling on land and water

[0103] (2) The ventilation and cooling system of the self-righting amphibious boat is equipped with independent cooling channels and engine air intake channels, and the incoming air is diverted and diffused by partitioned guide fans to ensure the independent operation of the cooling area and the engine air intake area.

[0104] (3) When the self-righting amphibious boat is traveling on land, the heat dissipation channel is opened, and the cold air flows into different areas through temperature detection and zoned guide fans to meet the cabin cooling and engine air intake needs.

[0105] (4) When the self-righting amphibious boat is traveling on the water, the risk of lake water intrusion during the driving process is detected by the amphibious boat attitude sensor and the air inlet is actively opened and closed to reduce the risk of water intrusion into the cabin of the self-righting amphibious boat.
