Problems solved by technology

Since the fan is installed on the engine through the fan shaft and connected to the engine as a whole, in order to reduce the loss of wind pressure, the blades of the fan are inserted into the air guide cover of the radiator, so that the fan and the air guide cover will often appear relatively large. Movement, in order to avoid damage caused by movement interference, a large radial relative movement gap is usually reserved between the fan and the windshield, and this gap will cause a decrease in wind pressure and return of hot air, greatly reducing the air flow, Reduce cooling efficiency

Embodiment Construction

[0021] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, steps, structure, The features and their effects are detailed.

[0022] see figure 1 As shown, it is a schematic diagram of hot air backflow and wind pressure loss caused by the gap between the fan and the air guide cover in the prior art, wherein the radial gap between the fan 4 and the air guide cover 8 causes local eddy currents in the air field (as shown by the arrows) ), resulting in hot air backflow and wind pressure loss, greatly reducing air flow and affecting heat dissipation performance.

[0023] In addition, the current cooling system of automobiles basically does not have a guiding design for the heat dissipation air flow field, resulting in the occurrence of wind pressure loss and hot air backflow everywhere, which seriously affect the heat dissipation performance.

[0024] see figure 2 As sh...

Abstract

The invention relates to a cooling system and a vehicle. The cooling system is used for performing heat dissipation on of an automobile engine, and comprises a radiator, a fan and a wind guide cover, wherein a universal joint is arranged mounted between the fan and the engine; and the fan is arranged mounted in the wind guide cover and can rotate relative to the wind guide cover. The universal joint principle is creatively utilized, so that the fact that large radial relative movement gap is reserved between the fan and the wind guide cover is avoided, direct hot air backflow and wind pressure loss caused by the gap are eliminated, and the heat -dissipating efficiency is improved.

Description

technical field [0001] The invention belongs to the field of cooling systems, in particular to a cooling system and a vehicle. Background technique [0002] The engine of the car generates a lot of heat when it is working. The cooling system is responsible for providing the engine with excess heat and is an important system to ensure the normal operation, safety, reliability and service life of the vehicle. The heat dissipation principle of the cooling system is to introduce the high-temperature coolant in the engine into the radiator, so that the low-temperature air in the environment flows through the radiator core under the action of the fan to exchange heat and take away the heat. [0003] Although the radiator and engine of the truck are installed on the frame, the engine and the radiator are different vibration sources. When the vehicle is running, the engine will often swing up and down with different driving conditions, while the radiator does not move. The latter p...
