[0031] As Figures 1-6 shown, an embodiment of the present utility model provides an air-cooled condenser, including a housing 10. A cooling pipe 20 is fixedly installed inside the housing 10. The cooling pipe 20 is used to cool the fluid, and heat dissipation fins 30 are fixedly installed on the surface of the cooling pipe 20. Specifically, the heat dissipation fins 30 are arranged at equal distances on the surface of the cooling pipe 20 to increase the surface area of the cooling pipe 20 and improve the heat dissipation efficiency. The housing 10 has a groove 11 for placing an air-cooling unit 40. The air-cooling unit 40 is used to strengthen air circulation and improve the heat dissipation efficiency. The air-cooling unit 40 is detachably installed in the groove 11 through a fixing unit 50. The air-cooling unit 40 includes an installation shell 41 and a fan 42 arranged inside the installation shell 41. The fixing unit 50 includes a knob 51 rotatably arranged outside the installation shell 41, two gears 52 rotatably arranged inside the installation shell 41 and meshing with each other, and a limiting block 53 inserted into the installation shell 41 and elastically connected to the two gears 52 respectively. The knob 51 is coaxially connected to one of the two gears 52 to drive the two gears 52 to rotate synchronously by rotating the knob 51, and then drive the two limiting blocks 53 to approach or move away from each other to abut against or separate the opposite inner walls of the groove 11.

[0032] In the embodiment of the present utility model, by arranging a knob 51 outside the installation shell 41, two meshing gears 52 and an elastically connected limiting block 53 inside, the quick installation and disassembly of the air-cooling unit 40 can be realized, which is convenient for maintenance.

[0033] Specifically, as Figures 4-5As shown in the figure, in the embodiment of the present utility model, two rotating shafts 54 are rotatably arranged in the mounting shell 41, and a traction rope 55 is wound around the outer walls of the two rotating shafts 54. The two ends of the traction rope 55 are respectively connected to a gear 52 and a limiting block 53. A support plate 56 is arranged in the mounting shell 41. One end of the traction rope 55 passes through the support plate 56 and is connected to the limiting block 53, and a spring 57 is arranged between the limiting block 53 and the support plate 56. The spring 57 is sleeved on the outer surface of the traction rope 55. By arranging two rotating shafts 54, a rotating shaft 54, a traction rope 55, a gear 52, a limiting block 53 and a spring 57 in the mounting shell 41, the rapid installation and disassembly of the air-cooling unit 40 can be realized.

[0034] During use, manually rotate the knob 51. The knob 51 drives a gear 52 coaxially connected to it to rotate. Since the two gears 52 are meshed with each other, the rotation of one gear 52 will drive the other gear 52 to rotate synchronously. The rotation of the gear 52 will drive the rotating shaft 54 to rotate. The rotating shaft 54 is wound with the traction rope 55. The rotation of the rotating shaft 54 will cause the traction rope 55 to be retracted and released. One end of the traction rope 55 is connected to the limiting block 53. As the traction rope 55 is retracted and released, the limiting block 53 moves along the inner wall of the mounting shell 41. The limiting blocks 53 approach each other. The limiting block 53 moves to abut against the opposite inner walls of the groove 11, realizing the fixed installation of the air-cooling unit 40. On the contrary, manually rotate the knob 51 in the reverse direction, so that the knob 51 drives a gear 52 coaxially connected to it to rotate in the reverse direction. The reverse rotation of one gear 52 will drive the other gear 52 to rotate synchronously in the reverse direction. The reverse rotation of the gear 52 will cause the rotating shaft 54 to rotate in the reverse direction, releasing the traction rope 55. As the traction rope 55 is released, the limiting block 53 moves along the inner wall of the mounting shell 41 under the action of the spring 57. The limiting blocks 53 move away from each other. The limiting block 53 separates from the opposite inner walls of the groove 11, and the air-cooling unit 40 can be easily taken out from the groove 11.

[0035] Specifically, as Figures 4-5 shown in the figure, in the embodiment of the present utility model, the traction rope 55 is slidably connected to the two rotating shafts 54, and the traction rope 55 is in a Z shape. The rotating shaft 54 guides and limits the traction rope 55 to facilitate corresponding operations on the limiting block 53.

[0036] Specifically, in the embodiment of the present utility model, a convex block (not shown in the figure) is arranged on one side end of the gear 52. The traction rope 55 is fixedly connected to the convex block. By fixedly connecting the traction rope 55 to the convex block, it can be ensured that the traction rope 55 will not slip or become loose during the rotation of the gear 52, that is, manually rotate the knob 51 to drive the gear 52 to rotate. The gear 52 drives the traction rope 55 to move through the convex block, realizing the movement of the limiting block 53.

[0037] Based on the above scheme, as Figure 3As shown, in the embodiment of the present utility model, limiting grooves 111 are provided on the opposite inner walls of the groove 11. The limiting blocks 53 can be clamped in the limiting grooves 111. By clamping the limiting blocks 53 in the limiting grooves 111, it can be ensured that the air-cooling unit 40 is more firmly fixed in the groove 11 during the installation process.

[0038] During use, by rotating the knob 51, the two gears 52 are rotated, so that the two traction ropes 55 can be pulled, thereby moving the two limiting blocks 53 towards the inside of the installation shell 41. In this way, the two limiting blocks 53 can be removed from the two limiting grooves 111, and then the installation shell 41 can be taken out from the groove 11, and thus the purpose of disassembling the air-cooling unit 40 can be achieved.

[0039] Based on the above solution, as Figure 3 shown, in the embodiment of the present utility model, a clamping block 43 is provided on one side of the installation shell 41, and a clamping groove 112 that is inserted and matched with the clamping block 43 is provided on one side wall of the groove 11. Through the cooperation of the clamping block 43 and the clamping groove 112, it can be ensured that the installation shell 41 is more firmly fixed in the groove 11 during the installation process.

[0040] Based on the above solution, as Figure 6 shown, in the embodiment of the present utility model, an isolation net 44 is provided at one end of the installation shell 41 close to the fan 42. The provided isolation net 44 can filter the incoming air, thereby removing part of the dust, reducing the dust accumulation speed of the heat dissipation fins 30, and thus reducing the work intensity of maintenance personnel.

[0041] Specifically, as Figure 6 shown, in the embodiment of the present utility model, a plurality of installation parts 441 are provided on the isolation net 44, and a plurality of limiting columns 411 corresponding to the plurality of installation parts 441 are provided on the installation shell 41. The plurality of installation parts 441 are respectively clamped on the plurality of limiting columns 411. The assembly of the isolation net 44 is facilitated through the limiting columns 411 and the installation parts 441 to facilitate the disassembly of the isolation net 44 for cleaning. Among them, the installation parts 441 can be made of an elastic material and are fixedly installed on the limiting columns 411 through deformation.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
