[0027] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0028] like Figure 1-3 As shown, an air-cooled heat exchanger includes a cooler 1, an air shroud 2 and a fan assembly 3. The air shroud 2 is fixedly arranged on one side of the cooler 1, and the fan assembly 3 is fixedly arranged on the other side of the air shroud 2. To facilitate the arrangement of the fan assembly 3, a circular hole adapted to the radius of the fan blade 31 of the fan assembly 3 is opened on the side of the air shroud 2 facing away from the cooler 1; the fan assembly 3 includes a fan blade 31, a motor 32 and a mesh cover 33. The motor 32 is fixed on the air shroud 2 with a fixed bracket, and the mesh cover 33 is fixed between the motor 32 and the air shroud 2 based on the air shroud 2. The fan blade 31 is coaxially fixed with the rotating shaft of the motor 32, and the rotation of the fan blade 31 is controlled by the motor 32. When the motor 32 is started, the fan assembly 3 starts to operate, and the cold air is drawn from the cooler 1 to the fan assembly 3, so as to assist the cooler 1 in achieving the heat dissipation process.

[0029] like Figure 4-6As shown, a plurality of inner channels 4 are arranged in parallel in the aforementioned cooler 1, a first fin 6 is fixedly arranged along the length direction of the inner channel 4, a gap area is arranged between adjacent inner channels 4, a second fin 7 is fixedly arranged in the gap area, and the first fin 6 and the second fin 7 are arranged crosswise. A seal 5 is also fixedly arranged in the gap area, the seal 5 is arranged along the width direction of the gap area, the seal 5 is arranged at the edge position of the gap area, and the second fin 7 is arranged in the middle position of the gap area. The gap area can be closed by the seal 5 arranged in the gap area, and the cross-arranged first fin 6 and the second fin 7, due to the continuous U-shaped structure of the first fin 6 and the second fin 7, there must be a connected area between the first fin 6 and the second fin 7 in the upper gap area and the lower gap area, thereby ensuring the overall fluidity of the cooler 1. The air inlet 11 and the air outlet 12 are arranged on the aforementioned cooler 1, which can ensure the overall air fluidity of the cooler 1, so that the cooling medium in the inner channel 4 is always in motion, ensuring the heat dissipation function of the cooler 1. The air outlet 12 and the air inlet 11 are both axially arranged on the side of the cooler 1 based on the inner channel 4, and the air outlet 12 and the air inlet 11 are arranged on opposite sides of the air guide cover 2.

[0030] In some embodiments, the second fin 7 is arranged in contact with the inner side of the seal 5, and the seal 5 and the second fin 7 are arranged at both ends of the gap area. The first fin 6 is fixed at the two ends of the inner channel 4 based on the length direction of the inner channel 4, and the second fin 7 is fixed in the gap area perpendicular to the first fin 6, so that the second fin 7 is only located at the two end positions of the cooler 1, which ensures the structural consistency of the cooler 1 to a certain extent; and because the second fin 7 is not completely filled in the gap area, the middle part of the gap area is transparent. At this time, the air is circulated through the cooler 1 by the fan assembly 3 and then discharged from the fan direction, which can better enhance the circulation of refrigerant around the cooler 1.

[0031] In order to facilitate the fixing of the air-cooled heat exchanger to the corresponding equipment, a group of fixing plates are fixedly arranged on the side of the air guide cover 2 facing the cooler 1, including an upper fixing plate and a lower fixing plate. The upper fixing plate and the lower fixing plate are both U-shaped structures, which are fixed to the air guide cover 2 in reverse by bolts. The cooler 1 is fixed by the gap between the upper fixing plate and the lower fixing plate. The bolt holes reserved on the fixing plates can facilitate the fixing of the air-cooled heat exchanger to the corresponding equipment.

[0032] It also includes a support leg 8 for supporting the air-cooled heat exchanger, which is fixed to the side of the air guide cover 2 with bolts, and a plurality of bolt holes are provided at the bottom of the support leg 8 to facilitate its fixing to the bottom side. To facilitate the transportation of the air-cooled heat exchanger, a lifting hole 9 is also provided on the side of the air guide cover 2.

[0033] A junction box 10 is fixedly arranged on the top of the air guide cover 2, and a wire outlet hole is opened on the side of the junction box 10. The junction box 10 is a flip-cover structure.
