Description

Technical Field

[0001] The utility model belongs to the technical field of automobile cooling systems, and more specifically, relates to an isolation structure between an automobile cooling fan and a radiator. Background Art

[0002] Electric vehicles are representatives of new energy vehicles. The cooling system is an important part of the vehicle's thermal management, and has a great impact on the reliability and economy of the battery, motor, and air conditioning performance of electric vehicles. The cooling system has a great impact on energy consumption. As the requirement for the driving range of electric vehicles is getting higher and higher, the requirement for the thermal balance control of the electric drive and battery is getting higher and higher. Therefore, the design and research of the cooling system are becoming more and more in-depth. The cooling fan is one of the core components of the cooling system, generally installed at the rear end of the radiator, and drives the air to perform forced ventilation through the control of the thermal manager to improve the cooling capacity of the radiator. With the improvement of the overall performance of electric vehicles, the increase in motor performance leads to an increase in the overall size, and other accessories in the front engine compartment also increase, gradually compressing the installation space of the front-end cooling module. The assembly gap between the fan and the radiator becomes smaller, and the slight deformation of the air shroud and the radiator makes it difficult to control the mating dimensions. To address the above problems, some automobiles currently begin to adopt a cooling fan air shroud with higher structural strength to reduce the deformation amount, thereby controlling the mating dimensions. However, the material price of the air shroud with higher structural strength is higher, which will increase the overall vehicle cost.

[0003] There is a technology with the name of "an engine fan system and an engine cooling system" and the publication number of "CN217055365U" in the prior art. This technology discloses an engine fan system, including: an air shroud, the air shroud is provided with a through installation port; a fan, the fan is installed in the installation port; wherein, the fan system is installed on the vehicle frame, the fan is driven by the engine, and an isolation member is provided between the fan and the engine to prevent the vibration generated by the engine from being transmitted to the fan. The engine fan system of the present application can isolate the vibration generated by the engine, which is beneficial to improving the reliability of the fan operation. On the one hand, by installing the fan system on the vehicle frame, that is, avoiding the direct connection between the air shroud and the engine, thereby preventing the vibration generated by the engine from being directly transmitted to the fan system. On the other hand, the present application uses an isolation member to strengthen the vibration isolation effect, which can prevent the vibration generated by the engine from being transmitted to the fan. Through the above two aspects, the engine vibration can be isolated to a large extent, thereby improving the reliability of the fan operation. However, this technology does not involve the technical solution of the present application. Summary of the Utility Model

[0010] The head portion and the body portion of the isolation rubber block are of an integral structure.

[0011] When the isolation rubber block is installed in the isolation rubber block mounting seat, the rubber block top of the head portion of the isolation rubber block abuts against the radiator reinforcement plate, and the body portion of the isolation rubber block passes through the mounting hole.

[0012] The rubber block bottom of the head portion of the isolation rubber block fits on the mounting seat end face of the isolation rubber block mounting seat.

[0013] A plurality of isolation rubber block mounting seats are arranged on the cooling fan air shroud, and one isolation rubber block is installed at each isolation rubber block mounting seat position.

The isolation rubber block mounting seat 3 includes a mounting hole 5. The isolation rubber block 2 includes a head portion 6 and a body portion 7. The head portion 6 and the body portion 7 are in a T-shaped structure. The body portion 7 includes a limiting convex portion 8 and a guiding portion 9. The above structure proposes an improved technical solution for the deficiencies in the prior art. When the installation space of the entire front-end module is very small, in order to meet the space layout requirements, the gap between the cooling fan and the radiator will be relatively small. When the cooling fan assembly vibrates due to the rotation of the fan blades during operation, there is a risk of direct interference between the cooling fan assembly and the radiator assembly; the radiator assembly will also undergo slight deformation during the normal operation of the vehicle. In the case of a small gap between the cooling fan assembly and the radiator assembly, there is also a risk of interference. Therefore, an isolation rubber block mounting seat 3 is arranged on the cooling fan air shroud 4, and at the same time, an isolation rubber block 2 is arranged.

The isolation rubber block 2 has a simple structure, small size, low cost, and does not occupy too much space. The isolation structure between the automotive cooling fan and the radiator described in the utility model has a simple structure, can avoid the direct contact between the fan and the radiator, and ensure the limit between the two, ensuring the dimensional fit between the cooling fan and the radiator.

In the case of a small gap between the cooling fan assembly and the radiator assembly, there is also a risk of interference. Therefore, an isolation rubber block mounting seat 3 is provided on the cooling fan air shroud 4, and at the same time, an isolation rubber block 2 is provided.
