[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Refer to Figures 1 - 3 , an embodiment provided by the present invention: a dry evaporator for a dry cooler, including: a rectangular housing 1 for protection, an airflow fan 9 is installed in the middle of the rear end of the rectangular housing 1, a protective door 3 is inserted into the inner wall of the right end of the rectangular housing 1, a pull ring 4 is slidably connected to the upper side of the right end of the protective door 3, two pull rods 5 rotatably connected to the front and rear sides of the bottom end of the pull ring 4, the opposite ends of two limiting plates 6 are rotatably connected to the bottom ends of the two pull rods 5, a connection block 23 is fixedly connected to the upper side of the right end of the rectangular housing 1, a spring 8 is fixedly connected to the bottom end of the connection block 23, and the bottom end of the spring 8 is fixedly connected to the bottom end of the pull ring 4. Both of the two limiting plates 6 are slidably connected to the lower side of the right end of the protective door 3, slots with the same size as the limiting plates 6 are opened on the front and rear sides of the right end of the rectangular housing 1, an evaporator body 2 is arranged on the inner wall of the bottom end of the rectangular housing 1, an end cover 7 is inserted into the right end of the evaporator body 2, a plurality of support blocks 10 are fixedly connected to the upper and lower sides of the right end of the evaporator body 2, an elastic plate 11 is fixedly connected to the right end of the support block 10, and a plurality of connection grooves 13 are opened on the upper and lower sides of the left end of the end cover 7. Among them, refer to Figure 4 and Figure 5 , a heat exchange tube 12 is fixedly connected to the inner wall of the bottom end of the evaporator body 2, a refrigerant inlet pipe 14 is fixedly connected to the front side of the bottom end of the heat exchange tube 12, a refrigerant outlet pipe 15 is fixedly connected to the rear side of the bottom end of the heat exchange tube 12, an inlet pipe 16 is fixedly connected to the left side of the top end of the evaporator body 2, an outlet pipe 17 is fixedly connected to the right side of the top end of the evaporator body 2, an air inlet hole with the same shape as the inlet pipe 16 is opened on the left side of the top end of the rectangular housing 1, and an air outlet hole with the same shape as the outlet pipe 17 is opened on the right side of the top end of the rectangular housing 1.

[0031] Specifically, when disassembling the dry evaporator, first pull the pull ring 4 on the protective door 3 to drive the movement of the pull rod 5. The pull rod 5 drives the movement of the limit plate 6 to disengage the limit on the protective door 3, so as to pull out the protective door 3 from the rectangular housing 1. During installation, insert the protective door 3 back into the rectangular housing 1. Due to the action of the connecting block 23 and the spring 8, the protective door 3 will automatically spring into the rectangular housing 1. After opening the protective door 3, move the end cover 7 forward to disengage the limit of the elastic plate 11 on the end cover 7, thereby opening the end cover 7 on the evaporator body 2. Then add refrigerant from the refrigerant inlet pipe 14, and it is also possible to clean and repair the evaporator body 2 and the heat exchange tubes 12, saving the time and labor costs required for installation and disassembly. There are two baffles on the connecting groove 13, and the distance between the baffles is the same as the size of the support block 10. Insert the support block 10 and the elastic plate 11 into the baffles, and the elastic plate 11 will be compressed into the connecting groove 13. The baffles limit the elastic plate 11. The size of the connecting groove 13 beside the baffles is the same as that of the elastic plate 11. Therefore, directly moving the end cover 7 can drive the elastic plate 11 to disengage from the connecting groove 13.

[0032] Referring to Figures 5 - 8 , the support frame 18 serving as a support role, the rear end of the support frame 18 is fixedly connected to the front end of the rectangular housing 1. The upper side of the inner wall of the support frame 18 is fixedly connected with a support plate 19. The rear side of the top end of the support plate 19 is rotatably connected with a cylindrical gear 20. A toothed plate 22 meshed with the front outer diameter of the cylindrical gear 20, the toothed plate 22 is slidably connected to the middle of the top end of the support plate 19. The front outer diameter of the toothed plate 22 is meshed with three spur gears 24. The bottom ends of the three spur gears 24 are rotatably connected to the top end of the support plate 19. The top ends of the three rotating rods 25 are fixedly connected to the inner walls of the three spur gears 24. The outer walls of the three rotating rods 25 are all rotatably connected to the inner wall of the support plate 19. The left and right ends of the three rotating rods 25 are fixedly connected with blades 26. The upper sides of the left and right ends of the support frame 18 are both provided with chutes. The left and right ends of the toothed plate 22 have the same shape as the chutes. The top end of the cylindrical gear 20 penetrates through the top end of the support frame 18 and is fixedly connected with a rotating button 21 for rotating the cylindrical gear 20.

[0033] Specifically, refrigerant is added through the refrigerant inlet pipe 14, and the evaporator body 2 and the heat exchange pipes 12 can also be cleaned and maintained, saving the time and labor costs required for installation and disassembly, improving work efficiency. The gas enters the evaporator body 2 through the inlet pipe 16 from the air inlet of the rectangular housing 1. After the refrigerant cools the gas, the temperature of the evaporator body 2 is reduced. Then, the air flow fan 9 is turned on to blow air. The rotary button 21 on the support frame 18 is used to rotate the cylindrical gear 20. The cylindrical gear 20 drives the toothed plate 22 to move left and right on the support plate 19. The movement of the toothed plate 22 drives the spur gear 24 to rotate, thereby driving the rotary rod 25 to rotate. The rotary rod 25 drives the blades 26 to rotate, thereby adjusting the wind speed to meet different working conditions and increasing the applicability of the device. The refrigerant outlet pipe 15 can be opened to replace the refrigerant. The temperature inside the set evaporator body 2 is maintained by the absorption and release of air between the inlet pipe 16 and the outlet pipe 17.

[0034] Working principle: When disassembling the dry evaporator, first pull the pull ring 4 on the protective door 3 to drive the pull rod 5 to move. The pull rod 5 drives the limit plate 6 to move away from the limit of the protective door 3, so as to pull out the protective door 3 from the rectangular housing 1. During installation, the protective door 3 is reinserted into the rectangular housing 1. Due to the action of the connecting block 23 and the spring 8, the protective door 3 will automatically spring into the rectangular housing 1. After opening the protective door 3, move the end cover 7 forward to disengage from the limit of the elastic plate 11 on the end cover 7, thereby opening the end cover 7 on the evaporator body 2. Then, refrigerant is added through the refrigerant inlet pipe 14, and the evaporator body 2 and the heat exchange pipes 12 can also be cleaned and maintained, saving the time and labor costs required for installation and disassembly, improving work efficiency. The gas enters the evaporator body 2 through the inlet pipe 16 from the air inlet of the rectangular housing 1. After the refrigerant cools the gas, the temperature of the evaporator body 2 is reduced. Then, the air flow fan 9 is turned on to blow air. The rotary button 21 on the support frame 18 is used to rotate the cylindrical gear 20. The cylindrical gear 20 drives the toothed plate 22 to move left and right on the support plate 19. The movement of the toothed plate 22 drives the spur gear 24 to rotate, thereby driving the rotary rod 25 to rotate. The rotary rod 25 drives the blades 26 to rotate, thereby adjusting the wind speed to meet different working conditions and increasing the applicability of the device.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
