[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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 of the embodiments. Based on the embodiments in 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.
[0032] Please refer to Figures 1 to 4 In the embodiment of the present utility model, an air cooler with an anti-freezing and blocking structure includes fixing plates 1 arranged oppositely at both ends. Between the opposite surfaces of the fixing plates 1, a plurality of cooling tubes 4 are fixedly arranged at intervals. Between the outer sides of the cooling tubes 4, a plurality of cooling fins 5 are fixedly arranged at intervals along the horizontal direction. On the fixing plates 1, a plurality of first through holes 2 are respectively arranged at intervals corresponding to the inner ring surfaces of the cooling tubes 4. On the surfaces of the fixing plates 1 away from the cooling tubes 4, fixing frames 6 are fixedly arranged. On the surfaces of the fixing frames 6 away from the fixing plates 1, baffles 7 are fixedly arranged. On the tops of the fixing frames 6, temperature sensors 9 are installed. The temperature sensors 9 can detect the temperature of the fluid inside the fixing frames 6, and the heating plates 12 can heat up the fluid inside the fixing frames 6. When in use, it helps to prevent freezing and blocking inside the fixing frames 6 of this air cooler. When stopping using this air cooler, it can conveniently control the temperature of the fluid inside the fixing frames 6 of this air cooler. When the external environmental temperature is relatively low in winter, it can prevent the fluid inside the fixing frames 6 of this air cooler from freezing, which helps to directly use this air cooler subsequently.
[0033] Among them, the temperature sensors 9 are all in a vertical state. The temperature sensors 9 all penetrate the inner and outer surfaces of the corresponding positions on the corresponding fixing frames 6. On the upper surfaces of the fixing frames 6 near one end of the heating plates 12, PLC controllers 10 are installed. The fixing frames 6 can fix and limit the PLC controllers 10; the PLC controllers 10 are electrically connected to the temperature sensors 9 at the corresponding ends, and the heating plates 12 are electrically connected to the PLC controllers 10 at the corresponding ends. The PLC controllers 10 help to control the switch of the heating plates 12; on the upper surfaces of the fixing frames 6 away from the PLC controllers 10, display screens 11 are installed. The display screens 11 are electrically connected to the temperature sensors 9 at the corresponding ends. The fixing frames 6 can fix and limit the display screens 11, which is convenient for stably using the display screens 11.
[0034] In the middle of the surfaces of the fixing frames 6 away from one end of the heating plates 12, connecting pipes 8 are fixedly arranged. In the middle of the fixing frames 6 near one end of the connecting pipes 8, second through holes 3 matching the inner ring surfaces of the connecting pipes 8 are respectively arranged. The fixing frames 6 can fix and limit the connecting pipes 8, which is convenient for stably using the connecting pipes 8; the first through holes 2 all penetrate the two opposite surfaces of the corresponding fixing plates 1 at the corresponding positions. The cooling tubes 4 are all in a horizontal state. On the cooling fins 5, a plurality of matching limiting holes 13 are respectively arranged at intervals corresponding to the cooling tubes 4. The cooling tubes 4 are fixedly connected to the corresponding positions on the cooling fins 5. The limiting holes 13 on the cooling fins 5 help to limit the cooling fins 5 and the cooling tubes 4.
[0035] At the bottom of the surfaces of the baffle plates 7 away from each other, mounting plates 14 are fixedly provided. The mounting plates 14 are all in a horizontal state. The mounting plates 14 are helpful for installing and limiting the baffle plates 7, facilitating the use of the baffle plates 7. In the middle of both ends of the mounting plates 14, bolts 15 are threadedly inserted in the vertical direction. The bolts 15 are all in a vertical state. The bolts 15 all penetrate the upper surface and the lower surface of the corresponding positions on the corresponding mounting plates 14. The bolts 15 can install and limit the mounting plates 14, facilitating the stable use of the mounting plates 14.
[0036] The working principle of the present utility model is as follows: During use, the lower surface of the mounting plate 14 is corresponded to the position outside that needs to be installed, so that the lower surface of the mounting plate 14 and the position outside that needs to be installed are in a matching and fitting state. Further, the mounting plate 14 and the position outside that needs to be installed are installed through the bolts 15. The bolts 15 can fix and limit the mounting plate 14, facilitating the stable use of the mounting plate 14. The mounting plate 14 can fix and limit the baffle plate 7, helping to stably use the baffle plate 7. The baffle plate 7 can fix and limit the fixed frame 6 and various components assembled on the fixed frame 6, facilitating the stable use of the fixed frame 6 and various components assembled on the fixed frame 6. The fixed frame 6 can fix and limit the fixing plate 1 and various components assembled on the fixing plate 1, helping to stably use the fixing plate 1 and various components assembled on the fixing plate 1.
[0037] When the air cooler needs to be used, one end of the connecting pipe 8 away from the fixed frame 6 is respectively connected to the external fluid supply pipe and the fluid discharge pipe. The external fluid supply pipe can transport the fluid to be cooled into the fixed frame 6 through the connecting pipe 8 and the second through hole 3 on the fixed frame 6. The baffle plate 7 can block the inside of the fixed frame 6. The fluid inside the fixed frame 6 will transport the fluid to be cooled to the other end of the fixed frame 6 through the first through hole 2 and the cooling pipe 4 on the fixing plate 1. The cooled fluid inside the fixed frame 6 will be discharged through the second through hole 3, the connecting pipe 8 and the external fluid discharge pipe on the corresponding fixed frame 6. The cooling pipe 4 and the cooling fins 5 are helpful for cooling the fluid passing through the cooling pipe 4.
[0038] When the use of this air cooler is stopped, the fluid is likely to remain in the fixed frame 6. When the external ambient temperature is relatively low, the fluid in the fixed frame 6 is likely to freeze. If the fluid in the fixed frame 6 freezes, it is likely to cause blockage in the fixed frame 6, affecting the subsequent direct use of this air cooler. When the temperature sensor 9 is turned on, the fixed frame 6 can fix and limit the temperature sensor 9, facilitating the stable use of the temperature sensor 9. In the state where the temperature sensor 9 is turned on, the temperature sensor 9 can detect the temperature of the fluid in the fixed frame 6 and transmit the detected temperature data to the display screen 11 for display, which helps the staff to observe. The fixed frame 6 can fix and limit the display screen 11, facilitating the stable use of the display screen 11. The temperature sensor 9 can transmit the detected temperature data information to the PLC controller 10. The fixed frame 6 can fix and limit the PLC controller 10, which helps to stably use the PLC controller 10.
[0039] When the temperature sensor 9 detects that the temperature data information in the fixed frame 6 is lower than the preset value, the PLC controller 10 will turn on the heating plate 12. The fixed frame 6 can fix and limit the heating plate 12, facilitating the stable use of the heating plate 12. In the state where the heating plate 12 is turned on, the heating plate 12 can heat up the fluid in the fixed frame 6. After the temperature sensor 9 detects that the fluid in the fixed frame 6 has been heated to the preset value, the heating plate 12 will be turned off through the PLC controller 10 to prevent the fluid in the fixed frame 6 from freezing and causing blockage in the fixed frame 6, so as to facilitate the anti-freezing and anti-blocking of the inner side of the fixed frame 6 and help the subsequent direct use of this air cooler.
[0040] During the use process, it helps to prevent anti-freezing and anti-blocking of the inner side of the fixed frame 6 in this air cooler. When the use of this air cooler is stopped, it can conveniently control the temperature of the fluid inside the fixed frame 6 in this air cooler. When the external ambient temperature is relatively low in winter, it can prevent the fluid inside the fixed frame 6 in this air cooler from freezing, which helps the subsequent direct use of this air cooler.
[0041] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
