Description

Technical Field

[0001] This invention belongs to the field of fluid machinery, and specifically relates to a cooling fan device for a dual-source locomotive diesel engine radiator. Background Technology

[0002] When a dual-source locomotive switches to diesel engine power supply mode, the diesel engine generates a lot of heat during operation. The matching diesel engine water cooling device (dual-source locomotive diesel engine radiator) absorbs this heat to dissipate it. Then, the cooling fan forces the water cooling device to cool and ventilate, carrying the heat from the air to the atmosphere outside the roof, thereby achieving the purpose of cooling the diesel engine.

[0003] When a diesel engine has a high power output, or operates at high power for extended periods, the cooling airflow demand on the diesel engine's water-cooling system increases. In such cases, existing fan configurations are insufficient to meet this airflow requirement. Therefore, how to satisfy the high airflow demand of the diesel engine's water-cooling system under these conditions has become a technical problem that needs to be solved. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides a cooling fan device for a dual-source locomotive diesel engine radiator.

[0006] The main body is constructed with an open structure at both ends. The upper end of the main body is connected to the radiator of the dual-source locomotive diesel engine, and the lower end is connected to the diesel engine.

[0007] The fan is installed on the main body.

[0008] The main body is configured to allow cold air introduced from the outside by the fan to flow through the main body and then blow onto and cool the dual-source locomotive diesel engine radiator.

[0009] As an extension of the above technical solution, the present invention also provides the following embodiments:

[0010] The main body includes a first skeleton and a second skeleton disposed below the first skeleton. Both the first skeleton and the second skeleton have rectangular outer contours, and the projection of the first skeleton in the horizontal direction includes the projection of the second skeleton in the horizontal direction.

[0012] It includes a support structure located on the outside of the main body, which serves to reinforce and protect the main body and the fan respectively.

[0013] The support unit includes a plurality of first supports extending downward at the side of the fan located below the first frame in an inward direction, and second supports connected to the lower ends of the first supports located on the same side of the first frame. Two adjacent first supports on any side are configured to be located on both sides of a fan, and a baffle located above the fan is provided between two adjacent first supports on any side.

[0014] A third support, which is the same number as the first support and is positioned correspondingly, is connected between the second support and the second frame.

[0015] The fans are positioned opposite each other and configured to be inclined from top to bottom on the first and second sides in a direction from the outside to the inside.

[0016] Both ends of the two second supports in the same direction are configured to be connected together by a fourth support.

[0017] The fans installed on the first side and the fans installed on the second side are symmetrically distributed.

[0018] In view of the problems existing in the prior art, the present invention also provides a cooling fan device for a dual-source locomotive diesel engine radiator.

[0019] The cooling fan device for the dual-source locomotive diesel engine radiator includes:

[0020] The main body is constructed as an open structure, with the upper end connected to the radiator of the dual-source locomotive diesel engine and the lower end connected to the diesel engine.

Detailed Implementation

[0031] The embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

[0032] like Figure 1 As shown, the cooling fan device 100 (hereinafter referred to as "cooling fan device 100") for a dual-source locomotive diesel engine radiator according to the present invention includes a main body 1 and a fan 3. The main body 1 is constructed with an open structure at both ends, and the upper end of the main body 1 is connected to the dual-source locomotive diesel engine radiator 2, and the lower end is connected to the diesel engine (not shown). The fan 3 is mounted on the main body 1, and the number of fans 3 can be adjusted according to the air volume requirements of the dual-source locomotive diesel engine radiator 2. In addition, the main body 1 is also constructed to allow the gas introduced from the outside by the fan 3 to flow through the main body 1 and finally blow onto and cool the dual-source locomotive diesel engine radiator 2.

[0033] During operation, the high-heat diesel engine located below the main body 1 conducts heat through a liquid pipeline (not shown) to the dual-source locomotive diesel engine radiator 2 located above the main body 1, causing the temperature of the dual-source locomotive diesel engine radiator 2 to rise. Simultaneously, the fan 3 is activated, drawing in cool outside air into the main body 1. After flowing through the main body 1, the cool air is blown towards the dual-source locomotive diesel engine radiator 2 located above the main body 1, thus completing the cooling operation of the dual-source locomotive diesel engine radiator 2.

[0034] As can be seen from the above description, the cooling fan device 100 according to the present invention, through the setting of the main body 1 and the combined use of the main body 1 and the fan 3, achieves the purpose of firmly assembling several fans 3 together on the dual-source locomotive to provide a large air volume for the dual-source locomotive diesel engine radiator 2 according to actual needs, thus meeting the demand of the dual-source locomotive diesel engine radiator 2 for a large cooling air volume and ensuring the smooth operation of the dual-source locomotive.

[0035] like Figures 1 to 3As shown, in one embodiment of the present invention, the main body 1 includes a first frame 11 and a second frame 12 disposed below the first frame 11. Both the first frame 11 and the second frame 12 have rectangular outer contours, and the projection of the first frame 11 in the horizontal direction can encompass the projection of the second frame 12 in the horizontal direction. This arrangement enhances the stability of the main body 1 structure, making the overall structure of the cooling fan device 100 more robust and reliable.

[0036] Furthermore, in one embodiment of the present invention, the main body 1 further includes a third frame (not shown) that extends downwardly from the four corners of the first frame 11 in an outward-inward direction and is connected to the four corners of the second frame 12 at corresponding positions. This arrangement further enhances the stability of the main body 1 structure.

[0037] In one embodiment of the present invention, the second frame 12 includes a plurality of support rods 121 disposed therein. This design improves the stability of the second frame 12 structure.

[0038] In one embodiment of the present invention, in order to enhance the strength of the connection, the first frame 11, the second frame 12, the support rod 121 and the third frame are connected together by welding.

[0039] like Figures 1 to 3 As shown, in one embodiment of the present invention, the main body 1 includes a first side 13, a second side 14, a third side 15, and a fourth side 16 disposed between the first frame 11 and the second frame 12, and a fan 3 is disposed on the outer side of at least one of the first side 13, the second side 14, the third side 15, and the fourth side 16. This embodiment has the following beneficial effects: firstly, it clarifies the installation position of the fan 3; secondly, it improves the stability of the main body 1 structure; and thirdly, it improves the sealing of the main body 1 structure, which can reduce the loss of cold air introduced by the fan 3, thereby improving the cooling efficiency of the cooling fan device 100.

[0040] like Figures 1 to 3 As shown, in one embodiment of the present invention, for the purpose of reinforcing the main body 1 and protecting the fan 3, the cooling fan device 100 includes a support portion 4 disposed on the outside of the main body 1.

[0041] Furthermore, in one embodiment of the present invention, the support portion 4 includes a first support 41 and a second support 42. The first support 41 extends downwardly from the side of the first frame 11 where the fan is located, inclined from the inside out. A second support 42 is connected to the lower end of the first support 41 on each side of the first frame 11. Additionally, two adjacent first support frames 41 on any one side are configured to be located on either side of a fan 3, and a baffle 43 is provided between two adjacent first support frames 41 on any one side, located above the fan 3. This arrangement, with a baffle 43 above each fan 3, prevents dust and debris from entering the fan 3, protecting it and helping to maintain its good working condition for a longer period, thus extending its service life.

[0042] Furthermore, in one embodiment of the present invention, the support portion 4 further includes a third support 44. The third support 44 is connected and disposed between the second support 42 and the second frame 12, and the number of third supports 44 is the same as that of the first supports 41, and their positions correspond to each other, that is, the arrangement of the third supports 44 and the first supports 41 has a one-to-one correspondence. Through this arrangement, reliable support is provided for the first supports 41 and the second supports 42, ensuring the normal functioning of the baffle 43, and also improving the overall firmness and stability of the main body 1.

[0043] Furthermore, for the purpose of simplifying the structure of the cooling fan device 100, in one embodiment of the present invention, the third bracket 44 is connected and disposed on the side where the fan 3 is disposed in the upper part of the second bracket 42 and the second frame 12.

[0044] In one embodiment of the present invention, in order to enhance the strength of the connection, the bracket parts 4 are connected to each other and to the main body 1 by welding.

[0045] like Figure 1 and Figure 3As shown, in one embodiment of the present invention, the fan 3 is disposed opposite to each other and constructed on a first side 13 and a second side 14 that are inclined downwards in a direction from the outside to the inside. Correspondingly, the cooling fan device 100 includes a plurality of first supports 41 extending downwards in a direction from the inside to the outside from the two sides of the first frame 11 where the fan 3 is disposed below; two second supports 42 respectively connected to the lower ends of the first supports 41 on both sides of the first frame 11; and a plurality of third supports 44 connected between the second supports 42 and the second frame 12, the same number of which are first supports 41 and corresponding in position. This design clarifies the installation position of the fan 3 and the specific arrangement of the first supports 41, second supports 42, and third supports 44, and also achieves the technical effects that the support portion 4 can achieve as described above. In addition, since the mounting surface of the fan 3 is also parallel to the first side 13 or the second side 14, the fan 3 after installation also has a corresponding tilt angle, thereby ensuring that the cold air introduced by the fan 3 is blown towards the dual-source locomotive diesel engine radiator 2 from bottom to top, thereby further improving the cooling efficiency of the cooling fan device 100.

[0046] Furthermore, in one embodiment of the present invention, for the purpose of improving the stability of the support portion 4, each of the two second supports 42 is configured to be connected together by a fourth support 45 at either end in the same direction. That is, a fourth support 45 is respectively provided on the front and rear sides of the cooling fan device 100.

[0047] like Figures 1 to 3 As shown, in one embodiment of the present invention, the fans 3 arranged on the first side 13 and the fans 3 arranged on the second side 14 are symmetrically distributed. This arrangement ensures that the airflow from both sides to the dual-source locomotive diesel engine radiator 2 is approximately equal, thus guaranteeing uniform cooling of the radiator 2 by the fans 3. Furthermore, this arrangement of the fans 3 also ensures that the load on both sides of the main body 1 is approximately equal, avoiding potential damage to the main body 1 due to load imbalance, thereby enhancing the structural stability of the main body 1 and increasing the service life of the cooling fan device 100.

[0048] Furthermore, based on the actual needs of the dual-source locomotive diesel engine radiator 2, four fans 3 are installed on the first side 13 and the second side 14 respectively.

[0049] In one embodiment of the present invention, the third side 15 and the fourth side 16 are arranged opposite each other and perpendicular to the horizontal plane. This design does not reduce the dimensions of the fan 3 in the direction of its arrangement, thus reserving space for installing more fans 3 and achieving the goal of expanding the applicability of the cooling fan device 100 according to the present invention.

[0050] The cooling fan device 100 according to the present invention can achieve the following technical effects:

[0051] First, by setting up the main body 1 and using the main body 1 in combination with the fan 3, the purpose of assembling several independent fans 3 together securely and reliably on the dual-source locomotive is achieved to provide a large air volume for the dual-source locomotive diesel engine radiator 2, thus meeting the demand of the dual-source locomotive diesel engine radiator 2 for a large cooling air volume and ensuring the smooth operation of the dual-source locomotive.

[0052] Secondly, the arrangement of the first frame 11, the second frame 12 and the support part 4 improves the stability of the main body 1 structure, the safety of the operation of the fan 3 and the service life of the fan 3.

[0053] In summary, the technical solution of the present invention has broad application prospects in this field.

[0055] Finally, it should be noted that although the present invention has been described in detail with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any way, provided there is no structural conflict.
