With the rapid development of industrial technology, fans have been widely applied in various fields such as household appliances, ships, automobiles, aviation and the like, and various fans such as air conditioning fans, range hood fans, automobile cooling fans and the like are in the future. The industrial fan is widely applied to the fields of automobiles and ships, and needs to provide enough cooling air volume for cooling the engine, but the requirement on the cooling capacity of an engine cooling system is continuously improved along with the increasing requirements on gas emission and comfort of human beings.
The cooling system is an important component of an engine cabin body, how to improve the cooling system and improve the heat dissipation performance of the cabin body is the key point of current research, the fuel economy and the emission performance of the engine are determined, the air guide system is an important component for cooling and heat dissipation of the engine, and the structure and the size characteristics of the air guide system have great influence on the air volume of a cooling fan of the engine.
When the engine compartment is arranged, the total height 1/2 or 1/3 of the fan is exposed out of the wind-protecting ring, a large part of wind volume can be blown to the sky side or the ground when the fan works, a considerable part of wind volume is lost, and upward or downward wind can bring raised dust, thereby influencing the normal work of the engine and the water tank and reducing the service life. The fan outlet wind direction is not concentrated, and the cooling effect on the engine is often influenced. The larger the power of the fan is, the more the air quantity is dissipated, which has obvious influence on the cooling capacity of a cooling system, the fuel economy of a power system, the resistance of circulating air in a vehicle body and the like. As shown in fig. 1, when a vehicle is loaded, the fan usually exposes the total height 1/2 or 1/3 outside the wind protection ring, a gap between the blade tip of the fan and the inner wall of the wind protection ring is called a blade tip gap, a considerable part of air can escape along the blade tip gap, the escaped air can blow to the sky side and the ground, a large amount of dust can be brought to an engine compartment, the dust can affect the normal operation of a water tank, the cooling capacity of the water tank is reduced or lost, and serious consequences such as high temperature are generated.
The prior art open fan outlet mechanism has the following disadvantages: firstly, gaps between the fan and the wind protection ring on the top side and the ground side are not shielded, and dust or other fine particles on the top side and the ground side of the engine compartment can be drawn into the engine compartment along with wind; secondly, because of serious dust pollution, after the vehicle is used for a period of time, the fins of the radiator are easy to block, and the heat dissipation capacity of a cooling system is sharply reduced; thirdly, wind at the bottom of the engine compartment deflects downwards and blows to the ground to cause a dust raising phenomenon, and the raised dust is attached to metal parts of the engine compartment to cause scaling of the engine and accelerate metal corrosion; fourthly, when the wind direction of the fan is directly blown to the ground, part of high-temperature gas is sucked into the cooling system again to generate hot air backflow, and the hot air backflow can relatively reduce the liquid-gas temperature difference of the radiator, so that the heat exchange efficiency of the radiator is influenced, and the heat dissipation capacity of the cooling system is finally influenced.
