Technical Field
The utility model belongs to the technical field of engine cooling systems, and particularly relates to an efficient cooling module.
Background
At present, the common matching form of the existing cooling module in the market is that a common air ring is matched with an opening fan, or a ring-shaped fan is matched with a C-shaped air ring; with the continuous improvement of the heat balance requirement of the whole vehicle, the installation space of a cooling fan in an engine compartment is continuously reduced, and the air quantity and the efficiency of a cooling module are difficult to improve in a limited space by a conventional cooling module; if the heat balance test of the whole vehicle fails, the most conventional solution is to replace a fan with larger air volume, but the current technical limit of a fan manufacturer is limited by installation space, the effect of the solution is generally difficult to meet the heat balance requirement, and finally, a cooling system of the whole vehicle needs to be adjusted, so that the whole project period is prolonged, and the project cost is increased.
Disclosure of Invention
The utility model aims to provide a high-efficiency cooling module with large air volume, high efficiency and compact structure.
In order to achieve the purpose, the utility model adopts the technical scheme that: an efficient cooling module comprises a fan, an air protecting ring and a radiator,
the fan comprises an outer ring, blades rotatably connected in the outer ring and a first connecting ring arranged on the periphery of the outer ring, wherein the downstream of each blade is a constant pressure area, and the upstream of each blade is a low pressure area;
the wind protection ring comprises a mounting frame and a second connecting ring which is connected to the rear end part of the mounting frame and extends in the center direction of the mounting frame;
the outer ring is arranged in the second connecting ring, a ventilation gap for returning gas from the normal pressure area to the low pressure area is formed between the outer ring and the second connecting ring, and the first connecting ring extends outwards towards the direction of the mounting frame and exceeds the ventilation gap.
In another preferred embodiment, the first connecting ring and the second connecting ring are both L-shaped.
In another refinement, the first connecting ring is located upstream of the outer ring and the blades;
in another preferred embodiment, the width of the ventilation gap is less than 20 mm.
In another preferred embodiment, the axial height of the second connection ring is greater than 10 mm.
In another preferred embodiment, the axial height of the first connecting ring is greater than 10 mm.
Due to the application of the technical scheme, compared with the prior art, the utility model has the following advantages: the first connecting ring and the second connecting ring can effectively block the backflow of the blade tip of the fan, reduce the turbulence intensity of the blade tip of the fan and reduce the noise of the fan; the air volume and efficiency can be higher in the same installation space, the efficiency can be effectively improved by 43%, the fan noise is lower, and the arrangement difficulty of an engine compartment of the whole vehicle is reduced; when the heat balance allowance of the whole vehicle is insufficient, sufficient axial space is available for fan design change or other structure change.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-4, the high-efficiency cooling module includes a fan 1, a wind-protecting ring 2 and a heat sink 3, wherein the fan 1 includes an outer ring 12, blades 13 rotatably connected in the outer ring 12, and a first connecting ring 11 disposed at the outer periphery of the outer ring, the downstream of the blades 13 is a normal pressure region, and the upstream of the blades 13 is a low pressure region; the wind protection ring 2 comprises a mounting frame 22 and a second connecting ring 21 which is connected to the rear end part of the mounting frame 22 and extends in the central direction of the mounting frame; the outer ring 12 is disposed in the second connection ring 21 and forms a ventilation gap therebetween for the backflow of gas from the normal pressure region to the low pressure region, and the first connection ring 11 extends outward in the direction of the mounting frame 22 and beyond the ventilation gap.
The first connection ring 11 and the second connection ring 12 are both L-shaped. Said first connecting ring 11 is located upstream of said outer ring 12 and of said blades 13; the width of the vent gap is less than 20 mm. The axial height of the secondary connecting ring 21 is greater than 10 mm. The axial height of the first connecting ring 11 is greater than 10 mm.
As shown in fig. 3-4, the first connecting ring 11 and the second connecting ring 21 form an L-shaped flow-blocking mechanism, the fan 1 rotates forward, the fan sucks air, and the blade tip flows back through the double L-shaped flow-blocking mechanism to flow back to the periphery inside the air-protecting ring without directly colliding with the intake air flow, so that the influence of the backflow on the air volume of the fan can be effectively reduced, the noise of the blade tip of the fan can be reduced, and the efficiency of the fan can be improved.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
