Description

Technical Field

[0001] This application relates to the technical field of heat dissipation systems, and particularly to a ventilation and cooling system for amphibious engineering equipment. Background Art

[0002] When a ship is operating on water, its power cooling system uses the water outside the ship for circulation to take away the excess heat generated by the power; vehicles traveling on land generally use an air suction fan, which inhales outside air and takes away heat through a radiator. At the same time, the power device is exposed to the outside and has good heat dissipation conditions. Amphibious engineering equipment needs to operate on land or water. Using water extraction for circulation heat dissipation cannot meet the land working conditions. And when the equipment is operating on water, to ensure the normal operation of its power system, it is also necessary to prevent water ingress. Generally, the power system is installed inside the engine room.

[0003] The power device is arranged inside the ship's hull, and the ventilation and heat dissipation conditions are relatively poor. Using air suction heat dissipation will cause a high ambient temperature in some parts of the power device, resulting in a high water temperature of the power device and causing the power system to be unable to work continuously for a long time. Therefore, amphibious engineering equipment requires a ventilation and cooling device that can meet the heat dissipation requirements for both water and land operations. Summary of the Utility Model

[0004] The technical problem to be solved by this utility model is that the existing engine room heat dissipation system has poor heat dissipation effect.

[0005] For this reason, this utility model provides a ventilation and cooling system for amphibious engineering equipment.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A ventilation and cooling system for amphibious engineering equipment includes:

[0008] A partition, which is arranged inside the engine room to divide the engine room into two independent installation rooms and a heat dissipation room, and the engine is installed in the installation room;

[0009] An air inlet, which is arranged at the top of the upper installation room of the engine room;

[0010] An air outlet, which is arranged at the top of the upper heat dissipation room of the engine room, and an exhaust fan is arranged at the air outlet.

[0011] Further, an exhaust duct is connected to the air outlet, and a louver and an electronic exhaust fan are connected inside the exhaust duct.

[0012] Further, the louver is arranged on the side of the electronic exhaust fan away from the water collecting tank.

[0013] Further, a plurality of the electronic exhaust fans are provided, and the plurality of electronic exhaust fans are arranged in an array on the same horizontal plane.

[0014] Further, a radiator is connected to the engine, and the radiator is arranged on one side of the engine facing the partition board.

[0015] Further, a fan is arranged on one side of the radiator away from the engine. The air inlet of the fan faces the radiator. The end face of the fan away from the radiator is connected to the partition board. A through hole is arranged on the partition board, and the air outlet of the fan is opposite to the through hole.

[0016] Further, the through hole is arranged near the bottom of the engine compartment.

[0017] Further, a grille is connected to the air inlet of the engine compartment. A water accumulation tank is arranged at the bottom of the grille. A drain pipe is connected to the installation room. One end of the drain pipe is connected to the water accumulation tank, and the other end is communicated with the outside of the engine compartment.

[0018] Further, a water accumulation tank is connected to the bottom of the exhaust duct. A drain pipe is connected to the heat dissipation room. One end of the drain pipe is connected to the water accumulation tank on the exhaust duct, and the other end is communicated with the outside of the engine compartment.

[0019] The beneficial effect of the present utility model is that in this application, a partition board is arranged in the engine compartment. The partition board separates the cold air in the installation room from the hot air in the heat dissipation room. An air inlet and an air outlet are arranged at the top of the engine compartment to realize the one-way propagation of the air inside the engine compartment towards the heat dissipation room. The heat is taken away from the engine compartment by the blowing fan, reducing the influence on the air temperature in the installation room, thereby avoiding the mutual influence of the cold and hot air, effectively improving the heat dissipation effect of the engine, thus being able to maintain the temperature of the engine body, providing a good working environment for the engine, and realizing the long-term stable operation of the power device.

[0026] A ventilation and cooling system for an amphibious engineering equipment is arranged in the engine room 1 of an amphibious engineering vehicle body. Specifically, the ventilation and cooling system includes a partition 2, an electronic exhaust fan 3, a drain pipe 13, and a water sump 4.

[0027] The partition 2 is fixedly connected inside the engine room 1. The partition 2 is vertically arranged, and the partition 2 divides the interior of the engine room 1 into two independent spaces, which are respectively an installation room 7 and a heat dissipation room 8. The engine 9 is installed on the partition 2, and the body of the engine 9 is located in the installation room 7.

[0028] Specifically, a radiator 10 and a fan 11 are connected to the engine 9. The radiator 10 is located between the engine 9 and the fan 11. The air inlet of the fan 11 faces the radiator 10. The end face of the fan 11 away from the radiator 10 is connected to the partition 2. A through hole is provided on the partition 2, and the through hole is arranged close to the bottom of the engine room 1. The air outlet of the fan 11 is opposite to the through hole. The number of engines 9 can be set to be multiple, and the number of through holes on the partition 2 is correspondingly set according to the number of engines 9.

[0029] At the top of the heat dissipation chamber 8 on the engine room 1, there is an air exhaust port 6. At the top of the installation chamber 7, there is an air inlet 5. The air inlet 5 is arranged on the deck surface. There can be multiple air inlets 5. At the air inlet 5 of the installation chamber 7, a grille 12 is connected. The grille 12 is a fixed steel grille 12. At the bottom of the grille 12, there is a water accumulation tank 4. Inside the installation chamber 7, a drain pipe 13 is connected. One end of the drain pipe 13 is connected to the water accumulation tank 4, and the other end is communicated with the outside of the engine room 1. At the air exhaust port 6, an exhaust duct is connected. Inside the exhaust duct, a louver and an electric exhaust fan 3 are connected. At the bottom of the exhaust duct, there is also a water accumulation tank 4. Inside the heat dissipation chamber 8, a drain pipe 13 is also connected. One end of the drain pipe 13 is connected to the water accumulation tank 4 on the exhaust duct, and the other end is communicated with the outside of the engine room 1. If the water on the deck surface enters the interior of the engine room 1, the water accumulates in the water accumulation tank 4. The air enters the installation chamber 7 through the grille 12, and the accumulated water in the water accumulation tank 4 can be discharged to the outside of the ship through the drain pipe 13.

[0030] It should be noted that the louver is arranged on the side of the electric exhaust fan 3 away from the water accumulation tank 4. The louver provides natural exhaust for the engine room 1, and the electric exhaust fan 3 provides forced exhaust for the interior of the engine room 1. There can be multiple electric exhaust fans 3. The arrangement of the multiple electric exhaust fans 3 can be arranged in the same horizontal plane, or arranged along the axis of the air exhaust port 6. The arrangement of the multiple electric exhaust fans 3 is not limited.

[0031] The implementation principle of this application is:

[0032] The heat generated by the operation of the engine 9 is discharged through the radiator 10. The fan 11 spreads the heat discharged by the radiator 10 towards the heat dissipation chamber 8. Due to the setting of the partition 2, the heat spreads towards the heat dissipation chamber 8, reducing the influence on the air temperature in the installation chamber 7, so as to be able to maintain the temperature of the engine 9 body.

[0033] In this process, the external cold air enters the installation chamber 7 through the air inlet 5. The cold air in the installation chamber 7 passes through the engine 9, discharges the heat of the engine 9 to the heat dissipation chamber 8 through the fan 11, and is discharged from the engine room 1 through the air exhaust port 6. The partition 2 separates the cold air in the installation chamber 7 from the hot air in the heat dissipation chamber 8, thus avoiding the mutual influence of hot and cold air and being able to effectively improve the heat dissipation effect of the engine 9.

[0034] In this embodiment, the air volume of the engine 9 fan 11 is 32400 m3 / h. Four electric exhaust fans 3 are arranged for forced exhaust, and the single exhaust air volume is 2010 m3 / h. The air volume exceeding the forced exhaust is discharged through natural exhaust. See the air flow field of the inlet and outlet.

[0035] Inspired by the above-described ideal embodiments of the present utility model, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present utility model. The technical scope of the present utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
