[0048] Specifically, the heat exchange device 3 includes a heat exchanger installation shell 32, a heat exchanger 33, a first connecting shell 34 and a second connecting shell 35; the two ends of the heat exchanger installation shell 32 are respectively connected to one end of the air induction device frame 10 and one end of the exhaust device 20, and the air inlet chamber 12 and the exhaust chamber 22 are both connected to the inner cavity of the heat exchanger installation shell 32; the heat exchanger 33 is installed in the heat exchanger installation shell 32, and the first heat exchange channel 30 and the second heat exchange channel 31 are provided in the heat exchanger 33; one end of the heat exchanger 33 is connected to one end of the first connecting shell 34, and the other end of the first connecting shell 34 is connected to the inner cavity of the heat exchanger installation shell 32; The heat exchanger 33 is connected to the outside through the air inlet chamber 12; the other end of the heat exchanger 33 is connected to one end of the second connecting shell 35, and the other end of the second connecting shell 35 is connected to the equipment to be cooled through the exhaust chamber 22; the air inlet chamber 12, the space 342 formed between the outer wall of the first connecting shell and the inner wall of the heat exchanger mounting shell, the first heat exchange channel 30, the space 343 formed between the outer wall of the second connecting shell and the inner wall of the heat exchanger mounting shell, and the exhaust chamber 22 are interconnected to form a first gas flow channel; the inner cavity 344 of the first connecting shell, the second heat exchange channel 31 and the inner cavity 350 of the second connecting shell are interconnected to form a second gas flow channel.

[0049] Specifically, in this embodiment, the heat exchanger mounting shell 32 is a square cylinder structure. Figure 5 As shown, the heat exchanger includes a plurality of heat exchange plates arranged at a set distance, a heat exchange channel is formed between two adjacent heat exchange plates, and end baffles are set at both ends of the heat exchange plates according to a certain rule. As shown in the figure, a specific embodiment of the heat exchanger is shown, which includes N heat exchange plates (N≥3), and end baffles are set at the middle positions of the ends of the 1st and 2nd, 3rd and 4th...2n+1st and 2n+2nd heat exchange plates (the shadow in the figure indicates the position where the end baffles are set) so that the heat exchange channel inlet and outlet of the first heat exchange channel are formed on both sides thereof, and end baffles are set at the positions on both sides of the ends of the 2nd and 3rd, 4th and 5th...2nth and 2n+1st heat exchange plates so that the middle thereof forms the heat exchange channel inlet and outlet of the second heat exchange channel. The inlet and outlet of the heat exchange channel, the first connecting shell and the second connecting shell are installed in the middle position of the end of the heat exchanger (the connection position of the connecting shell is indicated by the dotted box in the figure), so that the inner cavity of the first connecting shell and the second connecting shell is only connected with the heat exchange channel inlet and outlet of the second heat exchange channel, and the heat exchange channel inlet and outlet of the first heat exchange channel is only connected with the space formed between the outer wall of the first connecting shell and the inner wall of the heat exchanger installation shell and the space formed between the outer wall of the second connecting shell and the inner wall of the heat exchanger installation shell; further, in order to improve the heat exchange efficiency of the heat exchanger, an intermediate baffle can be set between two adjacent heat exchange plates as needed to change the gas flow direction in the heat exchange channel or increase the flow path.

[0050] The working principle of the wind tower evaporative indirect cooling device disclosed in this embodiment for heat exchange and cooling of high-temperature exhaust gas is as follows: the wind tower evaporative indirect cooling device disclosed in the utility model is installed in an open external environment, the induced draft device is at the upper end, the exhaust device is at the lower end, and the high-temperature exhaust gas generated by the factory is connected to the second connecting shell through a pipeline, and the generated high-temperature exhaust gas passes through the inner cavity of the second connecting shell, the second heat exchange channel of the heat exchanger and the inner cavity of the first connecting shell in turn after passing through the pipeline, and is discharged to the external environment; at the same time, because the wind tower evaporative indirect cooling device is placed in an open external environment, When there is airflow (wind) passing through from the outside, due to the Bernoulli principle, the air pressure on the side of the device facing the airflow is large (generating positive pressure), and the air pressure on the side away from the airflow is small (generating negative pressure). Therefore, the air induced device baffle on the side facing the airflow (windward side) in the air induced device of the device flips toward the inside of the air induced cavity under the action of the external airflow, so that the corresponding air inlet is opened, and the low-temperature airflow from the outside enters the air induced cavity through the air inlet, and the other air induced device baffles in the air induced device are buckled on the air induced device frame under the pressure of the internal and external airflows, thereby closing the other air inlets. Under the Bernoulli effect of the airflow, the exhaust device baffle facing the airflow side is buckled on the exhaust port, so that the corresponding exhaust port is closed. As for the exhaust device baffle located on the backflow side of the airflow, the pressure on the backflow side is smaller due to the Bernoulli effect. Therefore, the exhaust device baffle on the backflow side (negative pressure side) is turned toward the outside of the exhaust cavity under the action of the airflow in the exhaust cavity, thereby realizing the opening of the exhaust port. In actual use, one or more exhaust device baffles may be opened at the same time. At the same time, the heat exchange device is installed between the air induction device and the exhaust device. The airflow entering from the air inlet cavity passes through the space formed between the outer wall of the first connecting shell and the inner wall of the heat exchanger installation shell, the first heat exchange channel of the heat exchanger, the space formed between the outer wall of the second connecting shell and the inner wall of the heat exchanger installation shell, and the exhaust cavity in turn, and is discharged from the exhaust port. When the low-temperature airflow enters the first heat exchange channel of the heat exchanger, the low-temperature airflow in the first heat exchange channel of the heat exchanger exchanges heat with the high-temperature exhaust gas in the second heat exchange channel of the heat exchanger, thereby realizing the cooling of the high-temperature exhaust gas. The wind tower evaporative indirect cooling device disclosed in this embodiment completely utilizes external airflow to drive the gas circulation in the heat exchange device, achieving zero power consumption, reducing enterprise costs and carbon emissions, and at the same time has the energy-saving advantages of large heat dissipation area, low cost, easy installation, and utilizing wind energy as energy.

[0051] Further, the upper end of the air induction device baffle 11 is hinged to the air induction device frame 10, and in a free state, the air induction device baffle 11 is buckled on the air inlet 13 to close the air inlet 13. The upper end of the exhaust device baffle 21 is hinged to the exhaust device frame 20, and in a free state, the exhaust device baffle 21 is buckled on the exhaust port 23 to close the exhaust port 23.

[0052] Specifically, in the present application, the upper ends of the induced draft device baffle and the exhaust device baffle can be respectively hinged to the induced draft device frame and the exhaust device frame by structures such as a rotating shaft or a hinge or other low-resistance connection and fixing methods, so that the induced draft device baffle or the exhaust device baffle can be flipped under external force (the force of airflow), thereby realizing the opening of the air inlet or the exhaust outlet. At the same time, when there is no external force or the external force is small, it can automatically return to a closed state under the action of gravity, thereby ensuring the reliability of its operation and improving the efficiency of heat exchange using airflow.

[0053] Furthermore, the air induction device frame 10 is a columnar structure with a polygonal cross section, and an air inlet cavity 12 is provided in the columnar structure;

[0054] The exhaust device frame 20 is a columnar structure with a polygonal cross section, and an exhaust cavity 22 is provided in the columnar structure.

[0055] Specifically, the induced draft device frame and the exhaust device frame are both columnar structures with polygonal cross-sections. In the present embodiment, the induced draft device frame 10 has a regular octahedron in cross-section; the exhaust device frame 20 also has a regular octahedron in cross-section, that is, the induced draft device frame and the exhaust device frame each include eight side panels and two end panels, and the eight side panels are sequentially connected (welded) to each other to form an octagonal cylinder structure, and the inner cavity of the cylinder structure is the air inlet cavity or the air exhaust cavity, and end panels are respectively fixed on both sides, and openings are provided on the side panels to form air inlets or air exhaust ports. In the present embodiment, the openings on the side panels are square openings, and an opening is provided on the end panel at one end for connecting with the channel in the heat exchanger mounting shell. The polygonal column structure enables the wind tower evaporative indirect cooling device disclosed by the utility model to better utilize airflows in different directions, that is, no matter what direction of the airflow the wind tower evaporative indirect cooling device disclosed by the utility model is placed in, the induced draft device and the exhaust device can work normally, and the Bernoulli effect is more obvious when the airflow flows through a regular polygon, that is, when the airflow flows through a regular polygon, the pressure difference between the windward side and the leeward side is large, thereby forming a larger airflow difference between the induced draft device and the exhaust device, thereby increasing the airflow volume and airflow velocity passing through the heat exchange device, and improving the heat exchange efficiency.

[0056] Furthermore, the side wall of the air induction device frame 10 is provided with two or more layers of air inlets 13 in the circumferential direction, and the air induction device frame 10 is provided with a plurality of air induction device baffles 11 equal in number to the air inlets 13;

[0057] The side wall surface of the exhaust device frame 20 is circumferentially provided with two or more layers of exhaust ports 23 , and the exhaust device frame 20 is provided with a plurality of exhaust device baffles 21 equal in number to the exhaust ports 23 .

[0058] Specifically, in the present application, two sides or multiple layers of air inlets are set on the air induced device frame so that it can capture more airflow, and two or more layers of exhaust ports are set on the exhaust device frame to facilitate the discharge of airflow, thereby further improving the utilization of airflow and improving heat exchange efficiency.

[0059] Further, the first communicating housing 34 and the second communicating housing 35 have the same structure;

[0060] It includes a prism shell structure 340 and a cylindrical shell structure 341. The large-section end of the prism shell structure 340 is connected to the heat exchanger, and the small-section end of the prism shell structure 340 is connected to one end of the cylindrical shell structure 341. The prism shell structure can increase the connection area with the heat exchanger, thereby improving the heat exchange efficiency.

[0061] Furthermore, a water mist spraying device is also provided in the first air flow channel.

[0062] Specifically, in the present embodiment, a water mist spray device may be provided at one or more locations in the air inlet cavity 12, the space 342 formed between the outer wall of the first connecting shell and the inner wall of the heat exchanger mounting shell, the first heat exchange channel 30, the space 343 formed between the outer wall of the second connecting shell and the inner wall of the heat exchanger mounting shell, and the exhaust cavity 22. Since the wind tower evaporative indirect cooling device disclosed in the present application has the first heat exchange channel and the second heat exchange channel completely separated, that is, the first heat exchange channel and the second heat exchange channel are not interconnected, a water mist spray device is also provided in the first air flow channel, which can not only utilize the evaporation of water vapor to cool down and absorb heat, but also effectively reduce the air temperature to the dew point temperature or even lower than the dew point temperature of the air, thereby utilizing the low-temperature air to cool down the high-temperature exhaust gas. At the same time, the sprayed water mist will not enter the corresponding heat dissipation environment through the wind tower evaporative indirect cooling device, which not only ensures the heat dissipation efficiency, but also does not increase the humidity of the high-temperature exhaust gas, while improving the efficiency of the exhaust gas treatment equipment.

[0063] Example 2

[0064] like Figure 6 and Figure 7 The second embodiment of the wind tower evaporative indirect cooling device disclosed in the utility model is shown. The wind tower evaporative indirect cooling device disclosed in this embodiment can be used in application scenarios such as server rooms, pharmaceutical production, printing industry, and textile industry, which need to isolate the heat dissipation environment from the external environment. In this embodiment, the wind tower evaporative indirect cooling device includes an air induction device 1, an exhaust device 2, and a heat exchange device 3;

[0065] The air induction device 1 comprises an air induction device frame 10 and an air induction device baffle 11;

[0066] The air inlet cavity 12 is provided in the air inlet device frame 10, and a plurality of air inlets 13 connected to the air inlet cavity 12 are circumferentially arranged on the side wall of the air inlet device frame 10. A plurality of air inlet device baffles 11 are provided on the air inlet device frame 10, and the air inlet device baffles 11 can be flipped toward the inside of the air inlet cavity 12 under the push of external airflow to open the corresponding air inlet 13;

[0067] The exhaust device 2 includes an exhaust device frame 20 and an exhaust device baffle 21;

[0068] An exhaust cavity 22 is provided in the exhaust device frame 20, and a plurality of exhaust ports 23 in communication with the exhaust cavity 22 are circumferentially arranged on the side wall surface of the exhaust device frame 20. A plurality of exhaust device baffles 21 are provided on the exhaust device frame 20, and the exhaust device baffles 21 can be turned toward the outside of the exhaust cavity 22 to open the corresponding exhaust ports 23 under the push of the airflow in the exhaust cavity 22;

[0069] The heat exchange device 3 includes a first heat exchange channel 30 and a second heat exchange channel 31 capable of performing heat exchange, wherein the first heat exchange channel 30 is connected to the air inlet cavity 12 and the air exhaust cavity 22, and the second heat exchange channel 31 is connected to the equipment to be cooled;

[0070] The heat exchange device 3 includes a heat exchanger 33, an air induction device connecting shell 36 and an air exhaust device connecting shell 37;

[0071] The air induction device connection shell 36 and the air exhaust device connection shell 37 are respectively connected to the two ends of the heat exchanger 33, and the air induction device connection shell 36 and the air exhaust device connection shell 37 are located on the same side of the heat exchanger 33, the other end of the air induction device connection shell 36 is connected to one end of the air induction device frame 10, and the other end of the air exhaust device connection shell 37 is connected to one end of the air exhaust device frame 20;

[0072] The heat exchanger 33 is provided with a first heat exchange channel 30 and a second heat exchange channel 31;

[0073] The air inlet cavity 12, the inner cavity of the air induction device connected to the shell, the first heat exchange channel, the inner cavity of the exhaust device connected to the shell and the exhaust cavity are connected to each other to form a first gas flow channel; the second heat exchange channel is connected to the cooling device to form a second air flow channel. Figure 7 As shown in FIG. 1 , the heat exchanger is also formed by multiple heat exchange plates arranged at intervals, and a heat exchange channel is formed between two adjacent heat exchange plates. The shaded part in the figure indicates that an end baffle is arranged at the end, so that a channel is formed between the two heat exchange plates. In this embodiment, the first heat exchange channel is arranged horizontally, and the second heat exchange channel is arranged vertically, that is, the external airflow is arranged in Figure 6The direction of movement is horizontal from left to right, and the high-temperature airflow generated by the heat dissipation device moves vertically from bottom to top, thereby performing heat exchange.

[0074] The working principle of the wind tower evaporative indirect cooling device disclosed in the present embodiment for heat exchange and cooling in application environments such as server rooms is as follows. The following is an explanation taking the heat dissipation and cooling of a server room as an example: the draft device and the exhaust device of the wind tower evaporative indirect cooling device disclosed in the present invention are placed in the external environment, and the heat exchange device is placed in the server room. Since the draft device and the exhaust device of the wind tower evaporative indirect cooling device are placed in an open external environment, when there is airflow (wind) passing through the outside, due to the Bernoulli principle, the air pressure on the side of the device facing the airflow is large, and the air pressure on the side away from the airflow is small. Therefore, the draft device baffle on the side facing the airflow in the draft device of the device is flipped toward the inside of the draft cavity under the action of the external airflow, so that the corresponding air inlet is opened, and the low-temperature airflow from the outside enters the draft cavity through the air inlet, and the other draft device baffles in the draft device are buckled on the draft device frame under the pressure of the internal and external airflows, thereby closing the other air inlets. Similarly, under the Bernoulli effect of the airflow, the exhaust device baffle on the side of the airflow is buckled on the exhaust port, so that the corresponding exhaust port is closed. As for the exhaust device baffle on the backflow side of the airflow, due to the Bernoulli effect, the pressure on the backflow side is smaller. Therefore, the exhaust device baffle on the backflow side is flipped toward the outside of the exhaust cavity under the action of the airflow in the exhaust cavity, thereby realizing the opening of the exhaust port. At the same time, the heat exchange device is installed between the induced draft device and the exhaust device. The airflow entering from the air inlet cavity passes through the inner cavity of the induced draft device connected to the shell, the first heat exchange channel, the inner cavity of the exhaust device connected to the shell, and the exhaust cavity in sequence, and then is discharged from the exhaust port. When the low-temperature airflow enters the first heat exchange channel of the heat exchanger, the low-temperature airflow in the first heat exchange channel of the heat exchanger exchanges heat with the high-temperature airflow in the second heat exchange channel of the heat exchanger, thereby realizing the cooling of the server room. The wind tower evaporative indirect cooling device disclosed in this embodiment completely utilizes external airflow to drive the gas circulation in the heat exchange device, achieving zero power consumption, reducing enterprise costs and carbon emissions, and at the same time has the energy-saving advantages of large heat dissipation area, low cost, easy installation, and utilizing wind energy as energy.

[0075] Furthermore, a water mist spraying device is also provided in the first air flow channel.

[0076] In the following environments, in addition to heat dissipation and temperature reduction, humidity also needs to be strictly controlled:

[0077] Server room: In data centers and server rooms, a large number of computing devices generate a lot of heat when running, requiring an efficient cooling system to maintain a suitable temperature. However, high humidity can cause electronic equipment to get damp, increasing the risk of short circuits and corrosion. Therefore, the humidity in the room needs to be controlled, usually maintained between 40-55%, to ensure the safe operation of the equipment.

[0078] In pharmaceutical production, the temperature and humidity control of the environment is very strict to ensure the stability and effectiveness of the drugs. For example, some drugs are prone to moisture absorption and deterioration in a high humidity environment, affecting the efficacy.

[0079] During the printing process, paper and ink are very sensitive to humidity. Excessive humidity can cause paper deformation and ink diffusion, thus affecting printing quality. Therefore, the printing workshop needs to maintain a constant temperature and humidity.

[0080] Textile Industry: In the textile production process, humidity control affects the strength and quality of fibers and yarns. Excessive humidity may cause fiber swelling and deteriorate fabric quality.

[0081] In the wind tower evaporative indirect cooling device disclosed in the present application, since the first heat exchange channel and the second heat exchange channel are completely separated, that is, the first heat exchange channel and the second heat exchange channel are not interconnected, a water mist spraying device is also provided in the first air flow channel, which can not only utilize the evaporation of water vapor to cool down and absorb heat, but also effectively reduce the air temperature to the dew point temperature or even lower than the air dew point temperature, thereby utilizing the low-temperature air to cool the indoor production environment and exhaust gas, etc. At the same time, the sprayed water mist will not enter the corresponding heat dissipation environment through the wind tower evaporative indirect cooling device, which not only ensures the heat dissipation efficiency, but also does not affect the humidity of the heat dissipation environment.

[0082] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
