[0033] The working principle of the embodiment is as follows: the first rotating device 2015 rotates, the rotation of the first rotating device 2015 drives the rotation of the airfoil fan blade 2016 on the output shaft of the first rotating device 2015, since the airfoil fan blade 2016 is inclined, when the inclined airfoil fan blade 2016 rotates, the airfoil fan blade 2016 cuts into the air, in the process of rotation of the inclined airfoil fan blade 2016, one side of the airfoil fan blade 2016 pushes the air, so that the air generates a component velocity along the inclination direction of the airfoil fan blade 2016, thereby making the air advance, the air that advances wraps the cooling medium and moves away from the rectangular shell 2011 to the direction close to the first temperature insulation transmission pipe device 202, when the airflow that wraps the cooling medium leaves the rectangular shell 2011 and enters the first temperature insulation transmission pipe device 202, since the cooling medium transmission space of the first temperature insulation transmission pipe device 202 is smaller than the cooling medium transmission space of the rectangular shell 2011, the moving speed of the cooling medium wrapped by the airflow is increased in this process, then the moving cooling medium moves to the direction close to the cylindrical shell 204 at a faster moving speed under the push of the airflow, in the process of movement, since the first temperature insulation transmission pipe device 202 has strong temperature insulation capacity, the temperature of the cooling medium in this stage is hardly lost, then the airflow continues to move away from the first temperature insulation transmission pipe device 202 and enters the first leakage prevention connection device 203, then when the airflow that wraps the cooling medium leaves the first leakage prevention connection device 203 and enters the cylindrical shell 204, since the cooling medium transmission space of the cylindrical shell 204 is smaller than the cooling medium transmission space of the leakage prevention connection device, the moving speed of the cooling medium wrapped by the airflow is increased, the cooling medium that enters the cylindrical shell 204 moves along the spiral cavity 205, in this process, the heat of the cooling medium is continuously lost, and since the airflow is accelerated twice, the accumulation of dirt on the surface of the spiral cavity 205 is reduced, when the heat of the cooling medium is sufficiently lost and the cooling medium leaves the spiral cavity 205 and enters the second leakage prevention connection device 206, since the cooling medium transmission space of the second leakage prevention connection device 206 is smaller than the cooling medium transmission space of the spiral cavity 205, the moving speed of the cooling medium wrapped by the airflow is increased, so that the cooling medium wrapped by the airflow passes through the second temperature insulation transmission pipe device 207 into the inside of the tortuous pipe 2013 more quickly, when the cooling medium wrapped by the airflow leaves the second temperature insulation transmission pipe device 207 and enters the tortuous pipe 2013, since the cooling medium transmission space of the second temperature insulation transmission pipe device 207 is smaller than the cooling medium transmission space of the tortuous pipe 2013, the moving speed of the cooling medium that enters the tortuous pipe 2013 is reduced, then since the temperature reduction device 2012 wraps the tortuous pipe 2013, the heat of the cooling medium in the inside of the tortuous pipe 2013 is absorbed and the temperature is reduced, when the cooling medium wrapped by the airflow leaves the tortuous pipe 2013 and enters the inside of the rectangular shell 2011,The cooling medium then re-enters the first temperature barrier pipe device 202 as the air flow moves, and the cycle continues.

[0034] Embodiment two, on the basis of embodiment one, please refer to Figures 6-10 The application provides a technical scheme: the condenser pipe device 3 comprises a second cylindrical shell 301, the axis of the second cylindrical shell 301 coincides with the axis position of the cylindrical shell section 204, the second cylindrical shell 301 is located inside the cylindrical shell section 204, the second cylindrical shell 301 is fixedly connected with a triangular arrangement pipe bundle 302 inside, the triangular arrangement pipe bundle 302 is provided with an internally threaded pipe bundle 303 inside, the turbulent effect and the spiral structure of the internally threaded pipe bundle 303 can reduce the accumulation of dirt on the pipe wall, keep efficient heat transfer, one end of the second cylindrical shell 301 close to the second leak-proof connecting device 206 is fixedly connected with an air inlet 304, the air inlet 304 is gradually expanded in shape, one end of the second cylindrical shell 301 close to the first leak-proof connecting device 203 is fixedly connected with an air outlet 305, the size of the air inlet 304 is inconsistent with the minimum inner diameter of the air outlet 305, the air outlet 305 is gradually tapered in shape, one end of the air outlet 305 away from the second cylindrical shell 301 is fixedly connected with a bifurcated pipe device 306, the bifurcated pipe device 306 is used for separating and discharging the condensed gas and the condensed liquid, the inner wall diameter of the bifurcated pipe device 306 is consistent with the minimum inner wall diameter of the air outlet 305, the bifurcated pipe device 306 comprises a connecting pipe port 3061, the connecting pipe port 3061 is provided with an upper pipe port 3062 away from the second cylindrical shell 301, the upper pipe port 3062 is fixedly connected with a first filter screen 3063 inside, the bottom of the upper pipe port 3062 is provided with a lower pipe port 3064, the lower pipe port 3064 is fixedly connected with a second filter screen 3065 inside, the precision size of the first filter screen 3063 is consistent with that of the second filter screen 3065, the first filter screen 3063 and the second filter screen 3065 are used for avoiding impurities outside from entering the device, and causing damage to the efficiency and structure of the device.

[0035] The working principle of the embodiment is as follows: the gas to be condensed enters the gas inlet 304, and then the gas enters the triangular arrangement pipe bundle 302. Since the space of the gas inlet 304 is larger than that of the triangular arrangement pipe bundle 302, the flow speed of the gas increases after leaving the gas inlet 304 and entering the triangular arrangement pipe bundle 302. At the same time, the internal thread pipe bundle 303 in the triangular arrangement pipe bundle 302 increases the contact area between the gas and the triangular arrangement pipe bundle 302. During the movement of the gas in the triangular arrangement pipe bundle 302, the gas gradually condenses. Then, the condensed gas and the liquid generated after condensation leave the triangular arrangement pipe bundle 302 and enter the gas outlet 305. Since the space of the triangular arrangement pipe bundle 302 is smaller than that of the gas outlet 305, the flow speed of the gas decreases. Then, the condensed gas continues to move and leaves the gas outlet 305 together with the liquid generated after condensation, and enters the bifurcated pipe device 306 through the connecting pipe opening 3061. The condensed gas rises along the pipe and is discharged from the upper pipe opening 3062. The liquid generated after condensation falls along the pipe and is discharged from the lower pipe opening 3064. When the device works outdoors, the first filter screen 3063 and the second filter screen 3065 located at the upper pipe opening 3062 and the lower pipe opening 3064 block large impurities from the outside.

[0036] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
