[0003] However, there are certain defects. When the air-temperature vaporizer is working, it will take away a lot of heat when vaporizing the low-temperature medium, causing frost on the surface of the aluminum fins. After a period of use, frost will form. If the frost is not handled in time after formation, it will affect the gasification capacity of the air-temperature vaporizer. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a heat exchange tube structure for an air-temperature vaporizer, which solves the problem that when the air-temperature vaporizer vaporizes the low-temperature medium during operation, a large amount of heat is taken away, causing frost to form on the surface of the aluminum fins.

[0012] The utility model provides a heat exchange tube structure of an air temperature type vaporizer. Compared with the prior art, the following beneficial effects are achieved:

[0013] 1. A heat exchange tube structure of an air temperature type vaporizer. The bevel gear drives the side bevel gear and the second side bevel gear meshing on its surface to rotate, driving the scraping plate sleeved outside the lead screw to scrape the ice and frost on the surface of the aluminum finned tube under the fixing action of the connecting rod. When the connecting rod moves to the spring arranged at one end of the fixing member, under the blocking action of the spring, the connecting piece at one end of the lead screw sleeved at the bottom is driven to move, changing the position where the limiting ball at the bottom of the telescopic spring is clamped inside the limiting groove, driving the object clamped by the steering member arranged at the other end of the lead screw, so that the scraping plate can move back and forth on the surface of the aluminum finned tube to scrape the ice and frost, avoiding the surface of the aluminum finned tube from being frozen too thick due to long-term use, which affects the normal use of the machine.

[0014] 2. A heat exchange tube structure of an air temperature type vaporizer.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: a heat exchange tube structure of an air-temperature type vaporizer. It includes a housing assembly 1, and a heat exchange component 2 is arranged inside the housing assembly 1. The heat exchange component 2 includes an aluminum finned tube 21. A fixing plate 22 is fixedly connected between the top gaps of the protrusions around the aluminum finned tube 21. A connecting rod 28 is fixedly connected to the middle of the fixing plate 22. Fixing pieces 25 are fixedly connected to both ends of the connecting rod 28. A spring 26 is fixedly connected to one end of the fixing piece 25. A scraper 23 is sleeved outside the connecting rod 28. The bottom of the scraper 23 is movably connected to a lead screw 27. A side bevel gear 210 and a second side bevel gear 211 are fixedly connected to one end of the lead screw 27. A bevel gear 29 meshes with the bottoms of the side bevel gear 210 and the second side bevel gear 211. The housing assembly 1 includes a fixed frame 11, and a diversion pipe 12 is arranged inside the fixed frame 11. The aluminum finned tube 21 uses natural convection of air to heat the low-temperature liquid in the heat exchange tube, so that it is completely evaporated into gas. When frost forms inside the aluminum finned tube 21 due to work, the lead screw 27 will drive the sleeved scraper 23 to perform defrosting operation on the surface of the aluminum finned tube 21 under the fixing action of the connecting rod 28.

[0024] Please refer to Figures 1-4, the aluminum finned tube 21 is sleeved outside the diversion tube 12. The bottom of the aluminum finned tube 21 is fixedly connected to the bottom of the inner cavity of the fixed frame 11. One end of the screw rod 27 is fixedly connected with a connecting piece 270. A limiting groove 271 is formed on the surface of the connecting piece 270. A hole is formed inside the fixing plate 22 and a telescopic spring 220 is fixedly connected inside. The bottom of the telescopic spring 220 is fixedly connected with a limiting ball 221. The limiting ball 221 is clamped inside the limiting groove 271. Since the screw rod 27 is connected inside the aluminum finned tube 21 through the fixing plate 22 and the extension plate 24, the limiting groove 271 formed on the side of the screw rod 27 moves towards the stressed end when the scraping plate 23 is squeezed by the spring 26, changing the meshing object of the steering piece 212 fixedly connected to the other end of the screw rod 27, so that the screw rod 27 rotates in the opposite direction to the previous one under the drive of the side bevel gear 210 and the second side bevel gear 211. The scraping plate 23 is slidably connected to one end of the spring 26 through the screw rod 27 and the connecting rod 28. One end of the aluminum finned tube 21 protrudes with an extension plate 24. The screw rod 27 is slidably connected inside the extension plate 24. The middle of the second side bevel gear 211 and the steering piece 212 is movably connected with the steering piece 212. A rack is arranged on the side of the second side bevel gear 211 and the steering piece 212. The steering piece 212 is fixedly connected to the surface of the screw rod 27 and is clamped on the side of the second side bevel gear 211 and the steering piece 212.

[0025] During use, when defrosting the surface of the aluminum finned tube 21 is required, first, the bevel gear 29 drives the side bevel gear 210 and the second side bevel gear 211 meshing on its surface to rotate, driving the scraping plate 23 sleeved outside the screw rod 27 to scrape the frost on the surface of the aluminum finned tube 21 under the fixing action of the connecting rod 28. When the connecting rod 28 moves to the spring 26 arranged at one end of the fixing member 25, under the blocking action of the spring 26, it drives the connecting piece 270 at one end of the screw rod 27 sleeved at the bottom to move. By changing the clamping object of the steering piece 212 inside the side bevel gear 210 and the second side bevel gear 211, since the side bevel gear 210 and the second side bevel gear 211 are meshed on the surface of the bevel gear 29 and rotate in opposite directions, when the steering piece 212 is clamped to different objects, the rotation direction of the screw rod 27 is different, enabling the scraping plate 23 to move back and forth on the surface of the aluminum finned tube 21 to scrape the frost.
