As shown in FIGS. 2 and 3, the tubular structure 12 has a hollow tube wall 126, that is, the inside of the tubular structure 12 is hollow, and the hollow tube wall 126 can be filled with heat transfer fluid to serve as a heat transfer fluid circulation box.

The first air guide fins 14 and the second air guide fins 16 are welded to the hollow tube wall 126 to form a gas passage 30. The gas passage 30 has an air inlet 302 and an air outlet 304 for air flow. However, the present case is not limited to this. The first air guiding fins 14 and the second air guiding fins 16 and the hollow tube wall 126 can also be fixedly connected by pasting, embedding, or the like.

In this embodiment, the base 18 is a cylindrical structure 182, and the upper end of the cylindrical structure 182 penetrates the hollow tube wall 126 of the tubular structure 12 to communicate with the gas channel 30. The side wall of the cylindrical structure 182 includes a hollow iron net 184 which is arranged around the wall of the cylindrical structure 182. The hollow iron net 184 is the air inlet of the cylindrical structure 182.

In this embodiment, the first air guide sheet 14 is a horn-shaped air guide tube 142 having a first nozzle 144 with a larger diameter and a second nozzle 146 with a smaller diameter. That is to say, the caliber of the first nozzle 144 is larger than the caliber of the second nozzle 146, and this arrangement facilitates air flow. The first nozzle 144 is disposed at the first port 122 of the tubular structure 12. As can be seen from the figure, the diameter of the first nozzle 144 is approximately equal to the diameter of the first port 122 of the tubular structure 12. As for the horn-shaped air duct 142 as a whole, it extends in the tubular structure 12. The second nozzle 146 is located at the second port 124 of the tubular structure 12. The second air guiding fin 16 is an annular air guiding tube 162 with an annular nozzle 164 extending into the second nozzle 146. Wherein, the diameter of the annular nozzle 164 is slightly smaller than the diameter of the second nozzle 146, so that a gap is formed between the pipe wall of the annular nozzle 164 and the pipe wall of the second nozzle 146 as the outlet of the gas channel 30.气口304。 Air port 304.

Referring to FIG. 2, the surface of the hollow tube wall 126 above the tubular structure 12 has a heat transfer fluid inlet 128, and the surface of the hollow tube wall 126 below the tubular structure 12 has a heat transfer fluid outlet 129. The heat transfer fluid inlet 128 and the heat transfer fluid The outlets 129 respectively communicate with the heat transfer liquid circulation tank. One end of the aforementioned introduction pipe 222 is connected to the pump 20, and the other end is connected to the heat transfer fluid inlet 128 for transferring the heat transfer fluid to the heat transfer fluid circulation tank. One end of the aforementioned outlet pipe 224 is connected to the pump 20, and the other end is connected to the heat transfer fluid outlet 129 for transferring the heat transfer fluid to the pump 20. In other words, the pump 20 is connected to the heat transfer liquid circulation tank through the introduction pipe 222 and the outlet pipe 224 to facilitate the transfer of the heat transfer liquid back and forth.

In addition, in this embodiment, the outer side wall surface 1262 of the hollow tube wall 126 is made of a low thermal conductivity material, and the thermal conductivity of the low thermal conductivity material is lower than 80W/(m.K) at room temperature. As a result, it can be effective Avoid the transfer of high or low temperature outside to the heat transfer fluid circulation box, which will make the temperature control effect of the heat transfer fluid worse. Further, the low thermal conductivity material may include stainless steel, iron, or the like. Furthermore, in an embodiment, the outer side wall surface 1262 of the hollow tube wall 126 is covered with a thermal insulation material, which can also achieve the effect of preventing the external high temperature or low temperature from being transferred to the heat transfer liquid circulation box.

The inner side wall surface 1264 of the hollow tube wall 126, the first air guide fins 14 and the second air guide fins 16 are all made of high thermal conductivity material, wherein the thermal conductivity of the high thermal conductivity material is higher than 200W/(m.K) at room temperature Therefore, the temperature of the airflow passing through the gas channel 30 can be effectively controlled. Further, the high thermal conductivity material may include copper or aluminum.

The thermal conductivity refers to the heat transfer through an area of 1 square meter in a certain period of time for a 1m thick material with a temperature difference of 1 degree (K) on both sides of the material, in watts/meter. Degree W/(m.K).

To further illustrate, the governor 26 is arranged below the cylindrical structure 182, and can be Related circuit boards and electronic components are coupled to the fan 24 for adjusting the rotation speed of the fan 24. In this way, the user can adjust the air volume of the bladeless fan 10.

The operation process of the circulatory temperature-controlled bladeless fan 10 of the present invention is as follows: when the fan 24 is started, the fan 24 sucks outside air into the base 18 and blows the air flow toward the air passage 30, and the air flow enters the air through the air inlet 302 In the channel 30, when the air flows in the gas channel 30, since it will contact the inner wall of the hollow tube wall 126, it will be affected by the temperature control effect of the heat transfer liquid in the heat transfer liquid circulation box, and then cool air or hot air will be blown out from the air outlet 304.

Due to the wall effect of fluid mechanics, when the airflow flows out from the gap of the air outlet 304, it will flow at a high speed against the pipe wall of the first wind deflector 14. The high-speed airflow will form a low pressure zone according to Bernoulli's principle. This low pressure area will suck in the outside air, and then rely on the viscosity of the airflow to drive this part of the air movement (after flowing out of the first nozzle 144, it will also drive a part of the air movement). In this way, the total air flow is much larger than the air flow itself, achieving the effect of air doubling. In addition, the gas sucked in through the second port 124 of the tubular structure 12 will also be affected by the heat transfer fluid in the heat transfer fluid circulation tank when passing through the tubular structure 12, resulting in a cooling or heating effect.

In summary, in the present invention, the space between the inner and outer pipe walls of the tubular structure 12 is designed as a heat transfer liquid circulation box to meet the cold or heat needs of users. In particular, since the hollow tube wall 126 of the tubular structure 12 surrounds the entire tube surface, whether the tube diameter of the tubular structure 12 is increased or the length of the tubular structure 12 is increased, the space of the heat transfer liquid circulation box can be increased. Or by increasing the distance between the inner and outer walls of the tubular structure 12, the space of the heat transfer liquid circulation box can also be increased. In this way, more heat transfer fluid can be filled in the hollow tube wall 126, thereby enhancing its cooling or heating effect on the airflow in the gas channel 30.

In addition, since the outer wall surface 1262 of the tubular structure 12 is made of low thermal conductivity material As a result, the inner wall surface 1264 and the two air guide fins 14 and 16 are made of high thermal conductivity materials, so it can effectively limit the heat transfer fluid to only have a temperature control effect on the airflow passing through the tubular structure 12. In particular, because the tubular structure 12 has a certain length, the gas sucked in from the second port 124 of the tubular structure 12 can also fully produce a cooling or heating effect after passing through the tubular structure 12 having a certain length.

Through the above detailed description of the preferred embodiments, it is hoped that the characteristics and spirit of the present invention can be described more clearly, and the scope of the present invention is not limited by the preferred embodiments disclosed above. On the contrary, its purpose is to cover various changes and equivalent arrangements within the scope of the patent application for the present invention.
