In addition, other related terms are subject to reasonable interpretation based on the relevant content provided in this specification.

[0031] Figure 1-Figure 2 As shown, the air cooler includes: a fan 1, which includes a motor 11 and a blade part 12 connected to the output shaft of the motor 11; a heat exchanger 2, which cools the hot fluid running in the heat exchanger 2 through the airflow generated by the fan 1; an upper shell 3, which forms a guide tube and is used to accommodate the blade part 12; a lower shell 4, which forms a guide cover and is used to install the heat exchanger 2, and the guide cover and the guide tube are connected to each other; a bracket 5, which is used to support the motor 11 on the guide tube and allow the output shaft of the motor 11 to pass downward through the bracket 5 to connect to the blade part 12; and a mesh cover 6, which is installed in the guide tube and is located in the bottom peripheral area of ​​the motor 11.

[0032] The upper shell 3 is provided with a bracket mounting structure, on which the bracket 5 is mounted. Specifically, the bracket mounting structure is formed by a local reinforcement structure of the upper shell material, which includes a plastic deformation local reinforcement area formed by plastic deformation of the cylinder body at the head of the guide tube.

[0033] Among them, the plastic deformation local reinforcement area includes a bell mouth formed by bending the cylinder of the head of the guide tube outward; the lip of the bell mouth constitutes a flange, and the flange is provided with connecting holes, and the bracket is installed on the flange by bolts (i.e., the second bolts 73 mentioned later) that cooperate with these connecting holes.

[0034] Among them, the upper shell 3 includes a flanging portion, which is formed by flanging on a slab; the remaining part of the upper shell formed on the slab is used to form the lower shell 4; the flanging portion forms the upper shell 3, and the mouth of the flanging portion is bent outward to form the bell mouth.

[0035] In which, the bracket 5 includes a core 51 and at least two connecting arms 52 circumferentially spaced around the core 51, and the outer ends of each connecting arm 52 of the at least two connecting arms 52 are respectively installed on the bracket mounting structure; the motor 11 is loaded on the core 51, and the output shaft of the motor 11 passes downward through the core 51 and is connected to the blade part 12.

[0036] The outer end of each connecting arm 52 of the at least two connecting arms 52 is provided with a curved connecting piece 53, and the curved connecting piece 53 has an outer portion and an inner portion, the outer portion is mounted on the bracket mounting structure, and the inner portion is connected to the outer end of the corresponding connecting arm 52, and the upper surface of the main body of the connecting arm 52 is lower than the upper surface of the outer portion, thereby forming a mesh cover placement groove on the upper surface of the main body of the connecting arm 52, and the mesh cover 6 is placed in the mesh cover placement groove.

[0037] The applicant has already described the above structure in detail in the prior application, and these descriptions can be incorporated into this specification and will not be repeated here.

[0038] Among them, such as Figure 2 As shown, the mesh cover 6 is composed of at least two independent mesh cover sectors 61, and the mesh cover 6 allows each part of the mesh cover sector 61 to be disassembled and assembled separately.

[0039] By designing the mesh cover 6 as at least two independent mesh cover sectors 61 and allowing each part of the mesh cover sector 61 to be disassembled and assembled separately, the problem of inconvenient mesh cover removal and placement when the installation and use space of the air cooler itself is solved, making the mesh cover disassembly and assembly during motor maintenance more convenient.

[0040] For example, when an air cooler is used in a wind turbine gearbox lubrication and cooling system, the air cooler's installation space is very limited because the wind turbine gearbox lubrication and cooling system is installed on the gearbox of the wind turbine generator. When the motor needs to be disassembled for maintenance, the mesh cover also needs to be disassembled. However, the mesh cover is a flat structure with a large area, which makes it inconvenient to remove and put the mesh cover. However, the area of ​​the mesh cover fan 61 is greatly reduced, which greatly increases the convenience of removing and putting the mesh cover fan 61.

[0041] In this embodiment, there are two mesh cover sectors 61 , and the two mesh cover sectors 61 have the same size.

[0042] In addition, each of the two mesh fan surfaces 61 is distributed with multiple reinforcements, and the bracket 5 is distributed with multiple clamping members, which act directly downward on the corresponding reinforcements, thereby fixing each mesh fan surface 61 above the bracket 5.

[0043] Specifically, a plurality of radial reinforcing ribs 62 are distributed on each mesh cover sector 61 , and the pressing members act directly downward on the radial reinforcing ribs 62 .

[0044] In addition, a portion of the clamping members is installed on the core 51 and acts directly downward on the inner side of the corresponding radial reinforcement rib 62 (i.e., the inward end), and a portion of the clamping members is installed on the outer end of the corresponding connecting arm 52 and acts directly downward on the outer side of the corresponding radial reinforcement rib 62 (i.e., the outward end).

[0045] Specifically, the clamping member installed on the core is a first bolt 71, and the inner side of the radial reinforcement rib 62 connected to the corresponding connection of the first bolt 71 has a mounting portion 621 (a ring formed by bending the end of the radial reinforcement rib 62), and the first bolt 71 passes through the corresponding mounting portion and presses the mounting portion downward on the base; the clamping member installed on the outer end of the corresponding connecting arm 52 is a pressure plate 72, and the pressure plate 72 is fixed to the outer end of the corresponding connecting arm 52 by a second bolt 73 while pressing the outer side of the corresponding radial reinforcement rib 62 downward.

[0046] Specifically, the first bolt 71 is also used to mount the base of the motor 11 on the core 51 ; the second bolt is also used to mount the outer end of the corresponding connecting arm 52 on the bracket mounting structure.

[0047] Here, the mesh fan 61 is fixed by two parts of the pressing parts: one part is the first bolt 71 installed on the core 51, which fixes the inner side of the radial reinforcement rib 62 by passing through the annular mounting portion 621 formed by bending the inner end of the corresponding radial reinforcement rib 62 and pressing the annular mounting portion 621 downward on the base of the motor 11, and at the same time has the installation function of the base of the motor 11; the other part is the pressure plate 72 installed on the outer end of the connecting arm 52, which is fastened to the outer end of the connecting arm 52 by the second bolt 73 while pressing the outer side of the radial reinforcement rib 62 downward, and the second bolt 73 has the installation function of the outer end of the connecting arm 52 and the bracket mounting structure, thereby achieving a firm compression of the inner and outer sides of the mesh fan 61.

[0048] The design of distributing multiple reinforcements on the mesh fan 61 and distributing multiple pressing parts on the bracket to directly act on the corresponding reinforcements, thereby fixing the mesh cover above the bracket, effectively solves the problem of the mesh cover easily colliding with the bracket and generating noise during the operation of the air cooler.

[0049] The above describes the relevant contents of this application. Based on these descriptions, a person of ordinary skill in the art will be able to implement this application. Based on the above contents of this specification, all other embodiments obtained by a person of ordinary skill in the art without making any creative efforts should fall within the scope of patent protection.
