Problems solved by technology

[0005] In the prior art, the structure of the wind protection ring used in the market is mainly divided into two types, one is the common and simple wind protection ring, the efficiency of the cooling fan is relatively low, and the noise is relatively high, the reason is that when the fan rotates, There is a large pressure difference between the return port area and the air outlet area, forming a vortex at the blade tip gap, causing a large backflow phenomenon, which reduces the performance of the cooling fan; the other is a labyrinth wind guard, and the labyrinth cooling Although the fan has high efficiency and reduces the return flow, but because of its complex structure, the manufacturing cost is high, and it must be used with a fan of a specific specification, the versatility is poor, and the use is seldom

Abstract

The invention discloses a flow guiding cooling system composed of an annular fan and a wind protecting ring. The flow guiding cooling system comprises a cooling package and also comprises a cooling bag frame, the wind protecting ring, a flow baffle plate and a reflux air duct. The cooling bag fame is fixed to the outer side of the cooling bag, one end of the wind protecting ring and the cooling bag frame are fixed together, and the other end of the wind protecting ring and the flow baffle plate are fastened through a fixing device to obtain the reflux air duct. By additionally arranging the reflux air flow on the flow baffle plate, reflux of gas is reduced and the trend of an air flow can be improved, so that the efficiency of the cooling fan is improved by 8-12%. The water temperature ofa water tank can be reduced by about 10 DEG C, and meanwhile, the cooling system has a noise-reducing effect and is simple in structure, low in cost, stable and reliable to work and relatively high inuniversality.

Description

technical field [0001] The invention relates to a component of an engine cooling system, in particular to a diversion cooling system composed of an annular fan and a wind guard. Background technique [0002] my country is a big energy consumer, but also an energy-short country. The per capita possession and consumption of resources and energy are far below the world average. With the continuous development of my country's automobile industry, higher requirements are put forward for automobile production cost and energy consumption control of automobile manufacturers. During the driving process of the car, the fan needs to run at high speed and accounts for 20-30% of the total running time of the vehicle. The silicone oil fan clutch can effectively reduce the power consumption of the engine, improve engine combustion, prolong the service life of the engine, save energy, reduce emissions and reduce noise, and improve User comfort. [0003] The cooling system of the engine is...
