However, in the related technology, there is a risk of water leakage in air conditioning cabinets, which in turn causes excessive humidity in the workshop. Utility Model Content

[0003] The main purpose of the utility model is to provide a wind cabinet, aiming to reduce the risk of high humidity in the surrounding environment caused by water leakage of the wind cabinet.

[0004] To achieve the above-mentioned purpose, the wind cabinet proposed in the utility model includes a casing, a heat exchanger, a fan, a liquid receiving container and a liquid leakage detection device; the casing is provided with an air inlet and an air outlet, and an air duct is provided in the casing, and the air duct connects the air inlet and the air outlet; the heat exchanger is arranged in the air duct; the fan is arranged in the air duct; the liquid receiving container is located in the casing and arranged below the heat exchanger; the liquid leakage detection device is arranged in the liquid receiving container and is electrically connected to the fan.

[0005] In the technical solution of the utility model, the casing is provided with an air inlet and an air outlet, an air duct connecting the air inlet and the air outlet is provided inside the casing, and the heat exchanger and the fan are both arranged in the air duct, so that the airflow enters the air duct through the air inlet, and after heat exchange through the heat exchanger in the air duct, the airflow after heat exchange is blown out from the air outlet by the driving force of the fan, thereby achieving the effect of adjusting the airflow temperature.

[0006] By placing the liquid receiving container inside the casing and below the heat exchanger, the liquid receiving container can receive the liquid leaking from the heat exchanger, reducing the risk of it flowing directly out of the casing. By placing a liquid leakage detection device inside the liquid receiving container and electrically connecting it to the fan, the liquid leakage detection device can automatically detect whether there is liquid leakage in the liquid receiving container, and then when it is detected that the leakage reaches a preset capacity value, it is convenient to control the fan to stop, reduce the risk of humid air blowing out from the air outlet, and thus reduce the risk of high humidity in the surrounding environment due to water leakage in the wind cabinet.

[0007] In one embodiment, the liquid receiving container is provided with a drain port, and the wind cabinet further includes a drain pipe and a drain valve, one end of the drain pipe is connected to the drain port, and the other end extends out of the casing, and the drain valve is arranged at the drain port or in the drain pipe.

[0008] With such a configuration, the liquid in the liquid receiving container can be promptly discharged to the outside of the housing through the liquid discharge pipe, thereby reducing the air humidity inside the housing, thereby reducing the risk of high-humidity airflow being blown out from the air outlet. In addition, by arranging the drain valve at the liquid discharge port or at the liquid discharge pipe, the drain valve can be used to control whether to drain the liquid in the liquid receiving container, thereby more flexibly balancing the air outlet efficiency and air outlet humidity.

[0009] In one embodiment, the drain valve is electrically connected to the liquid leakage detection device.

[0010] With such arrangement, the drain valve can be automatically opened or closed according to the signal sent by the leakage detection device, thus reducing the need for manual operation.

[0011] In one embodiment, the liquid drain port is disposed in the housing.

[0012] With such an arrangement, the liquid inlet end of the liquid discharge pipe connected to the liquid discharge port is also located inside the housing, thereby reducing the risk of liquid leakage at the connection between the two and direct leakage into the surrounding environment.

[0013] In one embodiment, the bottom wall of the liquid receiving container is arranged to be inclined downward from a side away from the liquid discharge port toward the liquid discharge port.

[0014] With such an arrangement, the leaked liquid in the wind cabinet can be guided to flow to the drain pipe in time, thereby effectively reducing the residual leaked liquid in the wind cabinet and accelerating the drainage speed.

[0015] In one embodiment, the heat exchanger includes a heat exchange tube, and the wind cabinet also includes a connecting pipe and a stop valve, one end of the connecting pipe is connected to the heat exchange tube, and the other end is connected to the drain pipe, and the stop valve is arranged on the connecting pipe.

[0017] In one embodiment, the heat exchange tube is provided with a liquid inlet interface, and the liquid inlet interface is provided inside the casing; and / or, the heat exchange tube is provided with a liquid outlet interface, and the liquid outlet interface is provided inside the casing.

[0018] With such an arrangement, when the heat exchange tube is connected to the pipeline of the cold source, the connection between the two is also located inside the casing, thereby reducing the risk of leakage directly flowing to the external surrounding environment when the connection between the two leaks.

[0019] In one embodiment, the wind cabinet further includes a humidity detector, and the humidity detector is disposed at one end of the air duct close to the air outlet.

[0020] Such an arrangement can further improve the effect of monitoring the humidity of the gas discharged from the air outlet, and thus corresponding actions can be taken in a timely manner according to the monitoring effect.

[0021] In one embodiment, the humidity detector is electrically connected to the fan.

[0022] With this arrangement, when the humidity sensor detects that the air humidity near the air outlet is high, a signal can be sent to the fan to control the fan to stop, thereby reducing the risk of relatively humid airflow flowing into the surrounding environment.

[0023] In one embodiment, a sound-absorbing member is provided on the inner wall of the housing.

[0024] This arrangement can reduce the noise emitted from inside the casing.

[0025] In one embodiment, the silencer is at least partially disposed around the fan.

[0026] Such a setting can effectively absorb and block the sound waves generated when the fan is running, thereby significantly reducing the noise level of the fan, thereby effectively reducing the noise of the wind cabinet.

[0027] In one embodiment, the fan is a brushless DC fan.

[0028] Such an arrangement can further reduce the noise of the fan during operation compared to a traditional fan.

[0029] In one embodiment, the wind cabinet further includes a first filter, and the first filter is arranged on the air inlet side of the heat exchanger.

[0031] In one embodiment, the wind cabinet further includes a second filter, and the second filter is arranged on the air outlet side of the heat exchanger.

[0032] Such an arrangement improves the quality of the airflow blown out from the air outlet.

[0033] In one embodiment, the wind cabinet further includes a return air valve, and the return air valve is arranged at the air inlet.

[0054] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0055] In the battery production process, in order to ensure a comfortable environment and process requirements, the temperature, humidity and cleanliness of the workshop need to be strictly controlled. Air conditioning cabinets have the function of controlling temperature and cleanliness, so they are widely used in lithium battery production plants. However, in the related art, there is a risk of water leakage in air conditioning cabinets, which in turn causes excessive humidity in the workshop. Therefore, how to reduce the risk of water leakage in air conditioning cabinets has become a problem that needs to be solved.

[0056] The batteries in the present invention include but are not limited to cylindrical batteries, rectangular batteries, etc.

[0057] In order to reduce the risk of high environmental humidity in a battery production workshop due to water leakage from a wind cabinet, the utility model provides a wind cabinet.

[0058] Please refer to Figure 1 and Figure 2 In one embodiment of the utility model, the wind cabinet includes a casing 100, a heat exchanger 200, a fan 300, a liquid receiving container 410 and a liquid leakage detection device 500; the casing 100 is provided with an air inlet 110 and an air outlet 120, and an air duct 130 is provided in the casing 100, and the air duct 130 connects the air inlet 110 and the air outlet 120; the heat exchanger 200 is arranged in the air duct 130; the fan 300 is arranged in the air duct 130; the liquid receiving container 410 is located in the casing 100 and is arranged below the heat exchanger 200; the liquid leakage detection device 500 is arranged in the liquid receiving container 410 and is electrically connected to the fan 300.

[0059] The casing 100 refers to a shell structure used to protect the heat exchange components and electrical components of the wind cabinet. The casing 100 can be a rectangular parallelepiped, a cylinder or other shapes. The casing 100 has an air inlet 110, an air outlet 120 and an air duct 130 connecting the air inlet 110 and the air outlet 120, wherein the air inlet 110 can be arranged on the side wall of the casing 100, or on the top wall of the casing 100, and the shape of the air inlet 110 can be rectangular, circular or other shapes. The air outlet 120 can also be arranged on the side wall of the casing 100, or on the top wall of the casing 100, and the shape of the air outlet 120 can be rectangular, circular or other shapes. The air duct 130 can be a channel formed by the inner wall of the casing 100, or it can be a pipe independent of the casing 100. The air duct 130 can be a straight line, a broken line, or a curved line, etc., as long as the airflow can enter the air duct 130 from the air inlet 110 of the casing 100, flow to the air outlet 120 through the air duct 130, and be blown out from the air outlet 120.

[0060] The heat exchanger 200 refers to a component for exchanging heat for the airflow entering the housing 100. The heat exchanger 200 may be in the shape of a rectangular parallelepiped, V-shaped or M-shaped as a whole. The heat exchanger 200 may include a heat exchange tube, in which a heat exchange medium is provided. When the airflow passes through the heat exchange tube, it exchanges heat with the heat exchange medium in the heat exchange tube, thereby achieving the effect of changing the temperature of the airflow. The heat exchange medium may be water or other refrigerants. The heat exchange tube may be a serpentine coil or a pipe of other shapes. The heat exchanger 200 may also include heat exchange fins located on the heat exchange tube. By providing the heat exchange fins, the heat exchange area of ​​the heat exchanger 200 may be increased, thereby improving the heat exchange efficiency of the heat exchanger 200. When the heat exchanger 200 is arranged in the air duct 130, it may be arranged in the middle of the air duct 130, or at one end of the air duct 130 close to the air inlet 110, or at one end of the air duct 130 close to the air outlet 120.

[0061] The fan 300 refers to a driving component for introducing external airflow into the air duct 130 of the housing 100 and sending the airflow in the air duct 130 out through the air outlet 120. When the fan 300 is arranged in the air duct 130, it can be arranged in the middle of the air duct 130, or at one end of the air duct 130 close to the air inlet 110, or at one end of the air duct 130 close to the air outlet 120. The fan 300 can be arranged on the air inlet side of the heat exchanger 200, or on the air outlet side of the heat exchanger 200. The fan 300 can be an axial flow fan 300, a centrifugal fan 300, a cross-flow fan 300, etc.

[0062] The liquid receiving container 410 refers to a container for receiving water in the housing 100 or other heat exchange liquids in the heat exchanger 200. It is understandable that the source of water leakage in the housing 100 is mainly located at the connection between the heat exchanger 200 and the external pipeline. By arranging the liquid receiving container 410 below the heat exchanger 200, the liquid leaking from the heat exchanger 200 can be received. The liquid receiving container 410 can be a box structure or a disc structure. The liquid receiving container 410 can be a rectangular parallelepiped, a semi-cylindrical shape or other shapes. The liquid receiving container 410 can be a plastic container or a metal container.

[0063] The liquid leakage detection device 500 refers to a device capable of detecting liquid leaking into the liquid receiving container 410, such as a liquid leakage detection belt, a liquid leakage detection rope, or a liquid level switch. When the liquid leakage detection device 500 is a liquid leakage detection belt or a liquid leakage detection rope, a conductive electrode is provided on the liquid leakage detection belt or the liquid leakage detection rope. When there is leaked liquid in the liquid receiving container 410, the liquid infiltrates the liquid leakage detection belt or the liquid leakage detection rope and contacts the conductive electrode to form a path. Then, when the current passes through a resistor on the path, the signal converter is activated, the electrical signal is converted into a digital signal, and an alarm signal is issued. Depending on the volume of the liquid, the resistance value on the path is different, and the converted digital signal is also displayed differently. In the technical solution of the utility model, a preset value can be set. When the volume of the leaked liquid reaches a certain amount, the converted digital signal will exceed the preset value, and then an alarm will be issued. With such a configuration, it is possible to further determine whether the wind cabinet is in operation according to whether the volume of the liquid changes, thereby ensuring that the leakage detection device 500 performs detection during the operation of the fan 300 and the heat exchanger 200, rather than when the wind cabinet is in a shutdown state, thereby reducing the risk of false alarms. Alternatively, the leakage detection device 500 can also be a liquid level switch, that is, a switch that can detect the liquid level. By setting the leakage detection device 500 as a liquid level switch, the liquid level in the liquid receiving container 410 can be detected, and a corresponding alarm signal can be issued. In the technical solution of the utility model, by electrically connecting the liquid leakage detection device 500 with the fan 300, the liquid leakage detection device 500 can detect whether the volume of the liquid in the liquid receiving container 410 has reached a preset value. If it has reached the preset value, it can be determined that there may be a risk of liquid leakage in the housing 100, which may cause the airflow blown out from the air outlet 120 to have a high humidity. Therefore, the signal can be sent to the fan 300, and the fan 300 can be controlled to be in a closed state, thereby reducing the risk of sending high-humidity airflow to the surrounding environment through the air outlet 120 of the wind cabinet. If it is detected that the volume of the liquid in the liquid receiving container 410 has not reached the preset value, it can be determined that although there may be a risk of liquid leakage in the housing 100, the amount of liquid leakage is not enough to have a significant impact on the humidity of the airflow blown out from the air outlet 120. Therefore, the fan 300 can be kept in the on state, so that the wind cabinet can discharge air normally.

[0064] In the technical solution of the utility model, the housing 100 is provided with an air inlet 110 and an air outlet 120, and an air duct 130 connecting the air inlet 110 and the air outlet 120 is provided in the housing 100, and the heat exchanger 200 and the fan 300 are both arranged in the air duct 130, so that the airflow enters the air duct 130 through the air inlet 110, and after heat exchange through the heat exchanger 200 in the air duct 130, the airflow after heat exchange is blown out from the air outlet 120 by the driving force of the fan 300, thereby achieving the effect of adjusting the airflow temperature. In addition, by arranging the liquid receiving container 410 in the housing 100 and below the heat exchanger 200, the liquid receiving container 410 can receive the liquid leaked from the heat exchanger 200, reducing the risk of it directly flowing out of the housing 100. By placing the leakage detection device 500 in the liquid receiving container 410 and electrically connecting it to the fan 300, the leakage detection device 500 can automatically detect whether there is leakage in the liquid receiving container 410, and then when it is detected that the leakage reaches a preset capacity value, it is convenient to control the fan 300 to stop, thereby reducing the risk of humid air being blown out from the air outlet 120, and thereby reducing the risk of high humidity in the surrounding environment due to water leakage in the wind cabinet.

[0065] Please refer to Figure 1 and Figure 2 In some embodiments of the utility model, the liquid receiving container 410 is provided with a drain port 412, and the wind cabinet also includes a drain pipe 420 and a drain valve 430, one end of the drain pipe 420 is connected to the drain port 412, and the other end extends out of the casing 100, and the drain valve 430 is arranged at the drain port 412 or in the drain pipe 420.

[0066] The drain port 412 is an opening for draining the liquid in the liquid receiving container 410. The drain port 412 may be circular, rectangular or in other shapes, and its size may be adapted to the size of the drain pipe 420. The drain port 412 may be provided on the side wall or the bottom wall 411 of the drain container.

[0067] The drain pipe 420 is a pipe connected to the drain port 412 and used to drain the liquid in the liquid receiving container 410 to the outside of the housing 100. The drain pipe 420 can be a hose or a hard pipe. The drain pipe 420 can be linear, curved or spiral.

[0068] The drain valve 430 refers to a control component for controlling whether the liquid in the liquid receiving container 410 is discharged through the drain pipe 420. The drain valve 430 can be an electric valve or a mechanical manual valve. The drain valve 430 can be arranged at the drain port 412 or in the drain pipe 420, as long as it can control whether the liquid in the liquid receiving container 410 is discharged to the outside of the housing 100. Specifically, when there is no leakage inside the housing 100, the fan 300 is kept in a normal operating state, and the drain valve 430 can be closed at this time, that is, the outlet of the liquid receiving container 410 and the drain pipe 420 are isolated from each other by the drain valve 430, thereby reducing the risk of the airflow being discharged through the drain pipe 420 and reducing energy loss. When the leakage detection device 500 detects leakage inside the casing 100, the fan 300 is turned off. At this time, the drain valve 430 can be opened, that is, the liquid receiving container 410 is connected to the outlet of the drain pipe 420, so that the liquid in the liquid receiving container 410 can be discharged through the drain pipe 420 in time.

[0069] By connecting one end of the drain pipe 420 to the drain port 412 and extending the other end outside the housing 100, the liquid in the liquid receiving container 410 can be promptly discharged to the outside of the housing 100 through the drain pipe 420, thereby reducing the air humidity inside the housing 100, thereby reducing the risk of high-humidity airflow being blown out from the air outlet 120. In addition, by arranging the drain valve 430 at the drain port 412 or at the drain pipe 420, the drain valve 430 can be used to control whether to drain the liquid in the liquid receiving container 410, thereby more flexibly balancing the air outlet efficiency and air outlet humidity.

[0070] In some embodiments of the present invention, the drain valve 430 is electrically connected to the liquid leakage detection device 500 .

[0071] By electrically connecting the drain valve 430 to the liquid leakage detection device 500, the drain valve 430 in the technical solution of the utility model can be automatically opened or closed according to the signal sent by the liquid leakage detection device 500, thereby reducing the need for manual operation.

[0072] Specifically, when the liquid leakage detection device 500 detects that the liquid in the liquid receiving container 410 reaches the preset capacity value, a liquid leakage signal is issued, and the drain valve 430 is in an open state after receiving the liquid leakage signal, thereby facilitating timely discharge of the liquid in the liquid receiving container 410 to the outside of the housing 100. When the liquid leakage detection device 500 does not detect that the liquid in the liquid receiving container 410 reaches the preset capacity value, no liquid leakage signal is issued to the drain valve 430, and the drain valve 430 remains in a closed state, thereby reducing the risk of airflow being discharged through the drain pipe 420.

[0073] like Figure 2 As shown, in some embodiments of the present invention, the drain port 412 is disposed in the housing 100 .

[0074] By arranging the drain port 412 in the housing 100 , the liquid inlet end of the drain pipe 420 connected to the drain port 412 is also located in the housing 100 , thereby reducing the risk of liquid leakage at the connection between the two and directly leaking into the surrounding environment.

[0075] like Figure 2 As shown, in some embodiments of the present invention, the bottom wall 411 of the liquid receiving container 410 is arranged to be inclined downward from the side away from the liquid discharge port 412 toward the liquid discharge port 412 .

[0076] The bottom wall 411 of the liquid receiving container 410 refers to the wall surface of the liquid receiving container 410 closest to the ground, based on the placement state of the wind cabinet when it is in normal working state. The bottom wall 411 of the liquid receiving container 410 can be a plane or a curved surface. Downward refers to the placement state of the wind cabinet when it is in normal working state, where the direction toward the ground is the downward direction, which can include a vertical downward direction or a direction that is at a certain angle to the vertical downward direction and points to the ground. The bottom wall 411 of the liquid receiving container 410 is set downwardly from the side away from the discharge port 412 toward the discharge port 412, which means that the position of the discharge port 412 of the liquid receiving container 410 is the lowest position. For example, when the discharge port 412 is set in the middle of the bottom wall 411 of the liquid receiving container 410, the bottom wall 411 of the liquid receiving container 410 can be conical, and each edge of the liquid receiving container 410 is set downwardly in the direction of the discharge port 412 in the middle. When the drain port 412 is disposed at the edge of the bottom wall 411 of the liquid receiving container 410 or at a side wall of the liquid receiving container 410, the bottom wall 411 of the liquid receiving container 410 can be an inclined plane, and the plane is inclined downward in the direction from the side away from the drain port 412 to the side close to the drain port 412.

[0077] By tilting the bottom wall 411 of the liquid receiving container 410 downward from the side away from the drain port 412 toward the drain port 412, the leaked liquid in the wind cabinet can be guided to flow to the drain pipe 420 in time, thereby effectively reducing the residual leaked liquid in the wind cabinet and speeding up the drainage speed.

[0078] like Figure 2 As shown, in some embodiments of the present invention, the heat exchanger 200 includes a heat exchange pipe, and the wind cabinet also includes a connecting pipe 800 and a stop valve 910. One end of the connecting pipe 800 is connected to the heat exchange pipe, and the other end is connected to the drain pipe 420. The stop valve 910 is arranged on the connecting pipe 800.

[0079] Heat exchange tubes refer to pipes used for heat exchange medium circulation. Heat exchange tubes can be straight tubes or serpentine tubes. In order to improve heat exchange efficiency, heat exchange tubes can be made of metal materials, such as copper tubes, aluminum tubes, etc.

[0080] The connecting pipe 800 refers to a pipe used to connect the heat exchange pipe with the drain pipe 420. The connecting pipe 800 can be a hose, such as a soft plastic pipe, a corrugated pipe, etc. The connecting pipe 800 can also be a hard pipe, such as a metal pipe or other plastic pipes that cannot be bent or deformed. The connecting pipe 800 can be a straight pipe or a curved pipe. The connecting pipe 800 can be a single pipe formed in one piece, or it can include at least two pipes, and the at least two pipes can be connected by a flange assembly.

[0081] The stop valve 910 refers to a control valve used to control whether the heat exchange medium in the heat exchange tube flows to the drain pipe 420. The stop valve 910 can be an electric valve or a mechanical manual valve. The stop valve 910 can be arranged at the joint of the heat exchange tube or on the connecting pipe 800. Specifically, when the leakage detection device 500 detects that the liquid in the liquid receiving container 410 reaches the preset capacity and determines that the heat exchanger 200 has a leakage, the stop valve 910 can be controlled to be in an open state, so that the heat exchange tube of the heat exchanger 200 is connected with the drain pipe 420 in time, and then the liquid working medium in the heat exchanger 200 is discharged through the drain pipe 420 in time; or, when the wind cabinet is in a long-term shutdown state, the stop valve 910 can be controlled to be in an open state, so that the heat exchange tube of the heat exchanger 200 is connected with the drain pipe 420 in time, and then the liquid working medium in the heat exchanger 200 is discharged through the drain pipe 420 in time. When the liquid leakage detection device 500 does not detect that the liquid in the liquid receiving container 410 has reached the preset capacity, the stop valve 910 can be controlled to be in the cut-off state, so as to timely isolate the heat exchange tube of the heat exchanger 200 from the liquid discharge pipe 420, thereby allowing the liquid working medium in the heat exchange tube to be in a normal circulation flow state, so as to ensure that the heat exchanger 200 is in a normal heat exchange state. Further, the stop valve 910 is electrically connected to the liquid leakage detection device 500, that is, the stop valve 910 is directly and automatically controlled to be in an open state or a cut-off state through the signal detected by the liquid leakage detection device 500, thereby reducing the situation of manual operation of the stop valve 910.

[0082] By connecting one end of the connecting pipe 800 to the heat exchange pipe and the other end to the drain pipe 420, and providing a stop valve 910 on the connecting pipe 800, whether the heat exchange pipe and the drain pipe 420 are connected can be controlled by the stop valve 910. Then, when the heat exchanger 200 is in a leaking state or the wind cabinet is in a shutdown state, the stop valve 910 is opened in time to connect the heat exchange pipe with the drain pipe 420, so that the liquid in the heat exchange pipe can be discharged in time to facilitate the maintenance of the heat exchange pipe. When the heat exchanger 200 is in a non-leaking state, the stop valve 910 is controlled to be in a cut-off state to cut off the channel between the heat exchange pipe and the drain pipe 420, thereby reducing the risk of the heat exchange medium in the heat exchange pipe flowing to the drain pipe 420, thereby ensuring that the heat exchange pipe can achieve an effective heat exchange effect.

[0083] like Figure 2As shown, in some embodiments of the present invention, the heat exchange tube is provided with a liquid inlet interface 210 , and the liquid inlet interface 210 is provided inside the housing 100 .

[0084] The liquid inlet interface 210 refers to an interface in the heat exchanger 200 for the heat exchange medium to flow in. The interface can be connected to the liquid outlet pipeline of the cold source.

[0085] By arranging the liquid inlet interface 210 of the heat exchange tube inside the casing 100, when the heat exchange tube is connected to the pipeline of the cold source, the connection between the two is also located inside the casing 100, thereby reducing the risk of liquid directly flowing to the external surrounding environment when leakage occurs at the connection between the two.

[0086] like Figure 2 As shown, in some embodiments of the present invention, the heat exchange tube is provided with a liquid outlet interface 220 , and the liquid outlet interface 220 is provided inside the housing 100 .

[0087] The liquid outlet interface 220 refers to an interface in the heat exchanger 200 for allowing the heat exchange medium to flow out to the cold source so that the heat exchange medium circulates. The interface can be connected to the liquid inlet pipeline of the cold source.

[0088] By arranging the liquid outlet interface 220 of the heat exchange tube inside the casing 100, when the heat exchange tube is connected to the pipeline of the cold source, the connection between the two is also located inside the casing 100, thereby reducing the risk of liquid directly flowing to the external surrounding environment when leakage occurs at the connection between the two.

[0089] like Figure 2 As shown, in some embodiments of the present invention, the wind cabinet further includes a humidity detector 600 , and the humidity detector 600 is disposed at one end of the air duct 130 close to the air outlet 120 .

[0090] The humidity detector 600 refers to a component used to detect the humidity of the airflow in the space where it is located. The humidity detector 600 can be a lithium chloride humidity sensor, an aluminum oxide sensor, or a ceramic humidity sensor. For example, the lithium chloride humidity sensor can be a resistive humidity sensor or a dew point meter. Further, the humidity detector 600 can use a dew point meter, which is an instrument that can detect and display both the temperature and humidity of the surrounding environment. It should be noted that the type and principle of the humidity detector 600 in the technical solution of the utility model are well-known technologies to those skilled in the art and will not be described in detail here.

[0091] By arranging a humidity detector 600 at one end of the air duct 130 near the air outlet 120, the effect of monitoring the humidity of the gas discharged from the air outlet 120 can be further improved, and corresponding actions can be taken in a timely manner according to the monitoring effect. Specifically, when the humidity detector 600 detects that the air humidity near the air outlet 120 is high, the wind cabinet can be controlled to shut down to reduce the risk of humid air flowing to the surrounding environment.

[0092] In some embodiments of the present invention, the humidity detector 600 is electrically connected to the fan 300 .

[0093] By electrically connecting the humidity detector 600 to the fan 300, when the humidity sensor detects that the air humidity near the air outlet 120 is high, a signal can be sent to the fan 300 to control the fan 300 to shut down, thereby reducing the risk of relatively humid airflow flowing into the surrounding environment.

[0094] In some embodiments of the present invention, the humidity detector 600 and the liquid leakage detection device 500 are both electrically connected to the fan 300 .

[0095] By electrically connecting the humidity detector 600 and the liquid leakage detection device 500 to the fan 300, the accuracy of controlling whether the fan 300 is shut down can be improved. For example, the fan 300 is controlled to shut down only when the liquid leakage detection device 500 detects a liquid leakage and the humidity detector 600 detects that the humidity of the airflow at the front end of the air outlet 120 is too high. If only the liquid leakage detection device 500 detects a liquid leakage, and the humidity detector 600 detects that the humidity of the airflow at the front end of the air outlet 120 is less than a preset threshold, the fan 300 can be controlled to remain in a normal operating state.

[0096] like Figure 3 As shown, in some embodiments of the present application, a sound-absorbing member 140 is provided on the inner wall of the housing 100 .

[0097] The muffler 140 is a component used to muffle the noise generated inside the housing 100. The muffler 140 can be a muffler cotton or a muffler plate with muffler holes. The muffler cotton is usually made of porous materials, such as glass fiber, and has good sound absorption performance. The muffler 140 can cover the entire inner wall of the housing 100, or can cover part of the inner wall of the housing 100.

[0098] By disposing the silencer 140 on the inner wall of the housing 100 , the noise emitted from the inside of the housing 100 can be reduced.

[0099] like Figure 3 As shown, further, the silencer 140 is disposed at least partially around the fan 300 .

[0100] It can be understood that the operation of the fan 300 is one of the main sources of noise generated inside the housing 100 .

[0101] By arranging the silencer 140 at least partially around the fan 300, the sound waves generated when the fan 300 is running can be effectively absorbed and blocked, thereby significantly reducing the noise level of the fan 300, thereby achieving the effect of effectively reducing the noise of the wind cabinet.

[0102] In some embodiments of the present invention, the fan 300 is a brushless DC fan 300 .

[0103] The brushless DC fan 300 refers to a fan 300 using a brushless DC motor, which may be a brushless DC centrifugal fan 300 or a brushless DC axial fan 300, etc.

[0104] By setting the fan 300 as a brushless DC fan 300, the noise of the fan 300 during operation can be further reduced compared with the traditional fan 300. In addition, the brushless DC fan 300 can also accurately control the power by electronically controlling the speed to meet different working requirements.

[0105] like Figure 1 As shown, in some embodiments of the present invention, the wind cabinet further includes a first filter 710 , and the first filter 710 is disposed on the air inlet side of the heat exchanger 200 .

[0106] The first filter 710 refers to a component that can perform preliminary filtering on the airflow entering the housing 100 , and can be a filter net or a filter component that filters some tiny impurities or harmful gases.

[0107] By setting a first filter 710 on the air inlet side of the heat exchanger 200, large particles of dust or other impurities entering the casing 100 can be coarsely filtered, reducing the risk of impurities clogging the air duct 130, and also allowing a cleaner air flow to be blown out from the air outlet 120.

[0108] like Figure 1 As shown, in some embodiments of the present invention, the wind cabinet further includes a second filter 720 , and the second filter 720 is disposed on the air outlet side of the heat exchanger 200 .

[0109] The first filter 710 refers to a component that can filter the airflow after heat exchange in the heat exchanger 200, and can be a filter component that filters some tiny impurities or harmful gases.

[0110] By providing a second filter 720 on the air outlet side of the heat exchanger 200 , the airflow after heat exchange in the heat exchanger 200 can be deeply filtered through the second filter 720 , thereby improving the quality of the airflow blown out from the air outlet 120 .

[0111] like Figure 1 As shown, in some embodiments of the present invention, the wind cabinet further includes a return air valve 920 , and the return air valve 920 is disposed at the air inlet 110 .

[0112] The return air valve 920 refers to a control valve for controlling whether the airflow can enter the housing 100 through the air inlet 110. The control valve can be an electric valve or a mechanical manual valve.

[0113] By arranging the return air valve 920 at the air inlet 110, it is possible to flexibly control whether the airflow enters the housing 100. Specifically, when the wind cabinet is in a shutdown state, the return air valve 920 can be closed to reduce the airflow and impurities carried in the airflow entering the housing 100 through the air inlet 110. When the wind cabinet is in a startup state, the return air valve 920 can be opened to achieve the effect of heat exchange with the surrounding air.

[0114] The above are only exemplary embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields are included in the patent protection scope of the present invention.
