Description
Technical Field
The invention relates to the technical field of engineering machinery, in particular to a heat dissipation system of an engine of a double-engine snow-sweeping vehicle.
Background
The double-engine snow sweeper is a snow sweeper provided with a main engine and a secondary engine. In the existing double-engine snow-removing vehicle, an auxiliary engine and a main engine are arranged in an engine cabin, the auxiliary engine is arranged at the front part of a vehicle frame, and the main engine is arranged at the rear part of the vehicle frame; the rear end of the main engine is provided with a main heat-emitting radiator, and the rear end of the auxiliary engine is provided with an auxiliary heat-emitting radiator; a main fan is arranged between the main engine and the main radiator, and a secondary fan is arranged between the secondary engine and the secondary radiator; when the engine is in operation, the main fan and the auxiliary fan both adopt an air suction mode to suck air to respective engines, so that heat generated by the engines is dissipated; however, in practical applications, the heat dissipation airflows of the two engines interfere with each other, and the hot air flow of the secondary engine sucked and emitted by the secondary fan is sucked by the primary fan positioned behind the secondary engine, so that the problem of poor heat dissipation effect of the primary engine is caused.
Disclosure of Invention
The invention provides an engine heat dissipation system of a double-engine snow-sweeping vehicle, which can solve the problem of poor heat dissipation effect caused by mutual interference of heat dissipation air flows of a main engine and a secondary engine of the existing double-engine snow-sweeping vehicle.
In order to solve the problems, the invention adopts the following technical scheme: the engine cooling system of the double-engine snow removal vehicle comprises a secondary radiator arranged in an engine cabin and positioned at the rear side of a secondary engine, and a primary radiator positioned at the rear side of a primary engine, wherein the engine cabin is divided into a primary engine cabin and a secondary engine cabin; the main engine cabin is provided with a fresh air inlet hole and a main cabin air dispersing hole, and the auxiliary engine cabin is provided with an auxiliary cabin air dispersing hole; a main fan for blowing gas to the main radiator is arranged between the main engine and the main radiator; a secondary fan is arranged between the secondary engine and the secondary radiator to suck the air in the primary engine compartment into the secondary engine compartment through the secondary radiator.
Among the above technical schemes, more specific technical schemes may also be: and a backflow prevention plate is arranged between the main engine cabin and the auxiliary engine cabin.
Further: the auxiliary radiator is embedded on the backflow prevention plate.
Further: the fresh air inlet hole is formed in the top wall and the side wall of the main engine cabin, and the main cabin air dispersing hole is formed in the rear wall of the main engine cabin.
Further: the auxiliary cabin air dispersing holes are formed in the side wall of the auxiliary engine cabin.
Due to the adoption of the technical scheme, compared with the prior art, the invention has the following beneficial effects:
1. since the engine compartment is divided into a main engine compartment and a sub-engine compartment; the main engine cabin is provided with a fresh air inlet and a main cabin air dispersing hole, and the auxiliary engine cabin is provided with an auxiliary cabin air dispersing hole; a main fan for blowing gas to the main radiator is arranged between the main engine and the main radiator; a secondary fan for sucking the air in the main engine cabin into the secondary engine cabin through the secondary radiator is arranged between the secondary engine and the secondary radiator; when the engine works, cool air enters the main engine cabin from the fresh air inlet hole, on one hand, cool air flow is formed by the main fan, the cool air passes through the main radiator to dissipate heat of the main engine, and the cool air is blown out of the cabin through the main cabin radiator hole; on the other hand, cold air flow is formed through the auxiliary fan, and is absorbed into the auxiliary engine cabin through the auxiliary radiator to radiate heat of the auxiliary engine, and flows out of the cabin through the auxiliary cabin air-radiating hole; therefore, the two radiating airflows are not interfered with each other, and the radiating efficiency is improved.
2. Because the backflow prevention plate is arranged between the main engine cabin and the auxiliary engine cabin; and plays a role in preventing the air flow from flowing back.
