[0026] The core of the present invention is to provide a fan cover structure for a radiator and a motorcycle for increasing air volume, which can further increase the effective air volume and improve the heat dissipation performance of the radiator.

[0027] In order to enable those skilled in the art to better understand the technical solution provided by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] Please refer to Figure 1-Figure 3 The present invention provides a fan cover structure for a radiator for increasing air volume, comprising a motor mounting support 101, a fan cover body 102 and a connecting bracket 103, wherein the motor mounting support 101 is connected with the fan motor 3, the fan cover body 102 is covered on the core of the radiator 2, the fan cover body 102 is a circular arc surface structure with a middle opening, and the motor mounting support 101 is located at the middle opening. The connecting bracket 103 is used to connect the motor mounting support 101 and the fan cover body 102. The middle opening area except for the shielding of the motor mounting support 101 and the connecting bracket 103 forms an exhaust port.

[0029] Compared with the ordinary cylindrical fan cover, the present invention provides a fan cover structure for a radiator with increased air volume. The fan cover body 102 is covered on the core of the radiator 2, and a motor mounting support 101 cooperating with the fan motor 3 is arranged in the center of the fan cover body 102. The fan cover body 102 and the motor mounting support 101 are connected by a connecting bracket 103. The two sides of the middle opening area are left empty except for the motor mounting support 101 and the connecting bracket 103 to avoid other components such as the frame. At the same time, as much space as possible is left for the fan airflow to be discharged, thereby reducing the exhaust resistance, further increasing the effective air volume, and improving the heat dissipation performance of the radiator.

[0030] In a specific embodiment, the radiator 2 is an arc-shaped radiator, and the fan cover 102 is a circular arc surface with a continuously changing circumference, and the outer edge of the circular arc surface of the fan cover 102 is closely matched with the core of the arc-shaped radiator. The fan cover 102 is a circular arc surface with a continuously changing circumference, and the outer edge of the circular arc surface is closely matched with the core of the arc-shaped radiator. Compared with other wind guide covers with similar structures, the special circular arc surface of this structure is designed according to the matching of the aerodynamic performance of the fan, and has been verified by iterative development of CFD fluid analysis and vehicle matching tests, and has excellent aerodynamic performance, which further improves the effective air volume.

[0031] In order to improve the connection strength, the present solution further includes a reinforcing rib 104 connecting the motor mounting support 101 and the fan cover 102 .

[0032] Specifically, the connecting bracket 103 is a plurality of connecting brackets arranged up and down. The fan cover 102 and the central motor mounting support 101 are composed of a plurality of connecting brackets and reinforcing ribs, with both sides left empty to avoid other components such as the frame, while leaving as much space as possible for the fan airflow to be discharged to reduce exhaust resistance.

[0033] Furthermore, one end of the connecting bracket 103 is provided with a mounting hole 1031 for connecting to the upper bracket 201 of the radiator, and the other end is provided with a latch 1032 for connecting to the lower bracket 202 of the radiator. Figure 1 As shown, the lower end of the connecting bracket 103 is inserted into the mounting hole of the lower bracket 202 of the radiator by two latches 1032, and the upper end of the connecting bracket 103 is provided with two mounting holes 1031 and fastened to the upper bracket 201 of the radiator by mounting bolts 4, so that the structure is compact and easy to assemble.

[0034] The fan cover 102 is provided with an inserting piece 1021 for fixing the motor connector 301. Specifically, the inserting piece 1021 is provided on the top of the fan cover. The inserting piece 1021 is a connecting plate provided with a bayonet.

[0035] Specifically, the motor mounting support 101 is an annular connecting plate provided with bolt mounting holes. The annular connecting plate is sleeved on the outer end of the fan motor, and the fan motor is connected to the bolt mounting holes on the annular connecting plate through mounting bolts.

[0036] In summary, the fan cover structure for the radiator for increasing air volume in this article mainly has the following characteristics:

[0037] 1. The structure cooperates with the rotating space of the motor fan blades and the arc-shaped radiator core, so that the entire covered area behind the radiator can form a stable negative pressure, increase the effective air volume flowing through the radiator, and enhance the heat dissipation performance of the radiator;

[0038] 2. As a mounting bracket for the motor fan, firmly connect it to the radiator;

[0039] 3. The top plug is used to fix the motor connector, which is simple and beautiful.

[0040] Compared with the ordinary cylindrical fan cover, this fan cover structure can effectively increase the effective air volume flowing through the radiator when the vehicle is at low speed and idling speed and the wind speed is low. At the same time, it can prevent the hot air blown backward from flowing back through the radiator core and participating in the next fan suction cycle, resulting in a decrease in the heat dissipation performance of the radiator. It is easy and firm to install, has high structural strength, and integrates the fixed structure of the motor connector, with high integration.

[0041] The present invention also provides a motorcycle, comprising a radiator 2, a fan motor 3 and a fan cover structure for the radiator for increasing the air volume. The fan cover structure for the radiator for increasing the air volume is the fan cover structure for the radiator for increasing the air volume described above. Therefore, the motorcycle having the fan cover structure for the radiator for increasing the air volume also has all the above-mentioned technical effects, which will not be described one by one here.

[0042] The principles and implementation methods of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
