Description

Technical Field

[0001] This utility model belongs to the field of fan technology, specifically relating to an automotive radiator fan with an integrated radiator protective strip. Background Technology

[0002] Cars, whether stationary or in motion, will encounter situations where they have to wade through water. When a car's radiator fan operates under these conditions, the fan blades are suddenly impacted by the liquid. Due to the reaction force in the direction of the fan's work, the liquid pushes the fan blades towards the radiator, posing a risk of damage. Some existing car radiator fans address this situation by adding a plastic baffle. This method has the following main problems and disadvantages:

[0003] 1. The blocking area is relatively small and cannot be applied to all scenarios;

[0004] 2. The split installation structure requires two sets of injection molds for the wind shield and baffle, necessitating manual assembly. This results in additional mold, labor, and management costs, leading to higher overall costs. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides an automotive radiator fan with an integrated radiator protective strip. The radiator protective strip has an increased blocking area, providing more effective protection for the radiator. The radiator protective strip is integrated with the fan cover, eliminating the need for additional assembly processes. This eliminates the need for mold development for the strip, reduces assembly labor costs, and eliminates the management costs associated with the strip.

[0006] The technical solution of this utility model is: a car radiator fan with an integrated radiator protective strip, including a fan blade, a motor and a wind shield; the motor is fixedly installed at the center of the fan blade, the fan blade with the motor is fixed to the front of the wind shield, and the back of the wind shield can be fixedly connected to the radiator.

[0007] The bottom back of the wind shield has an integrally molded radiator protective strip at the middle of the radiator and the fan blade; the highest point of the radiator protective strip is flush with the lowest point of the fan blade.

[0008] Furthermore, the radiator protective strip is an upwardly arched arc-shaped baffle, and the radiator protective strip is tangent to the effective diameter of the fan blade.

[0009] Furthermore, the wind shield is provided with multiple reinforcing ribs.

[0010] Furthermore, the radiator protective strip has multiple reinforcing ribs on the surface facing the radiator.

[0011] The beneficial effects of this utility model are: it provides an automotive radiator fan with an integrated radiator protective strip, which saves the mold development cost of the strip, the manual assembly cost of the strip, and the management cost of the strip.

[0012] The baffle strip and wind shield are integrated into one unit: Compared to assembled baffle blocks, the integrated baffle strip is stronger. No additional assembly process is required, eliminating the need for mold development for baffle blocks, reducing assembly labor costs, and eliminating baffle block management costs.

[0013] The baffle is located at the lower edge of the entire fan, between the fan blades and the radiator: the vehicle mainly wades through water starting from the lower edge of the fan. When the fan is operating normally, a sudden impact from the liquid will push the lower edge of the fan blades towards the radiator. Therefore, a protective baffle is placed at the lower edge of the fan, between the radiator and the fan blades, to prevent interference between the fan blades and the radiator, which could cause damage to the radiator.

[0014] The baffle bar should be tangent to the effective diameter of the fan blades: The fan's operating range is a circle with the motor shaft center as the center and the distance from the center to the outer circle of the fan blades as the radius. If the baffle bar falls within this circle, the output power will decrease under the same input power conditions; therefore, the baffle bar must be outside this circle. The purpose of tangency is to maximize the protection of the heat sink by the baffle bar. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figure 1-6 As shown, an automotive radiator fan with an integrated radiator protective strip includes a fan blade 1, a motor 2, and a radiator shield 3. The radiator shield 3 has multiple reinforcing ribs. The motor 2 is fixedly mounted at the center of the fan blade 1, and the fan blade 1 with the motor 2 is fixed to the front of the radiator shield 3. The back of the radiator shield 3 can be fixedly connected to the radiator 5. A radiator protective strip 4 is integrally injection molded at the bottom of the back of the radiator shield 3, between the radiator 5 and the fan blade 1. Multiple reinforcing ribs are provided on the surface of the radiator protective strip 4 facing the radiator 5. The highest point of the radiator protective strip 4 is flush with the lowest point of the blade 7 of the fan blade 1. Therefore, the main body of the radiator protective strip 4 and the bottom of the fan blade's protective ring 8 are on the same horizontal plane. When the fan is operating normally, if it is suddenly impacted by liquid, the impact force of the liquid will push the lower edge of the fan blade towards the radiator. The protective ring of the fan blade will be isolated by the radiator protective strip, preventing interference between the fan blade and the radiator, which could lead to damage or breakage of the radiator.

[0024] Preferably, the radiator protective baffle 4 is an upwardly arched arc-shaped baffle, and the radiator protective baffle 4 is tangent to the effective diameter of the blade 7 of the fan blade 1.

[0025] The baffle strip and wind shield are integrated into one unit: Compared to assembled baffle blocks, the integrated baffle strip is stronger. No additional assembly process is required, eliminating the need for mold development for baffle blocks, reducing assembly labor costs, and eliminating baffle block management costs.

[0026] The baffle is located at the lower edge of the entire fan, between the fan blades and the radiator: the vehicle mainly wades through water starting from the lower edge of the fan. When the fan is operating normally, a sudden impact from the liquid will push the lower edge of the fan blades towards the radiator. Therefore, a protective baffle is placed at the lower edge of the fan, between the radiator and the fan blades, to prevent interference between the fan blades and the radiator, which could cause damage to the radiator.

[0027] The baffle bar should be tangent to the effective diameter of the fan blades: The fan's operating range is a circle with the motor shaft center as the center and the distance from the center to the outer circle of the fan blades as the radius. If the baffle bar falls within this circle, the output power will decrease under the same input power conditions; therefore, the baffle bar must be outside this circle. The purpose of tangency is to maximize the protection of the heat sink by the baffle bar.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
