The energy storage device can be equipped with a heat exchange device to regulate the temperature of the battery. When the heat exchange device is working, it has a large noise, which greatly affects the working environment of the heat exchange device and the energy storage device.

[0005] In view of the above problems, the present application provides a heat exchange assembly, a sound insulation cover, a heat exchange device, an energy storage device and a charging system to at least alleviate the problem of large noise of the heat exchange device.

[0006] The first aspect of the present application provides a heat exchange assembly, comprising a shell, a first heat exchanger, an air flow guiding mechanism and a sound insulation cover, the shell has a containing cavity and a first wall, the first wall surrounds the containing cavity, and the first wall is provided with a first ventilation opening in communication with the containing cavity; the first heat exchanger is arranged in the containing cavity and is used for heat exchange with external air flow; the air flow guiding mechanism is arranged at the first ventilation opening and is used for guiding the air flow to flow through the first heat exchanger; the sound insulation cover is arranged to connect the first wall and surround the first ventilation opening and the air flow guiding mechanism; wherein the sound insulation cover comprises a ventilation structure, the ventilation structure is arranged corresponding to the first wall, the ventilation structure comprises a plurality of air guide pieces arranged at intervals along a first direction, and the adjacent air guide pieces have ventilation gaps, each air guide piece is arranged to extend in a second direction, and the first direction intersects the second direction.

[0007] In the technical scheme of the present application, the ventilation structure of the sound insulation cover can meet the air inlet and outlet requirements of the heat exchange device, and at the same time, the noise generated during the operation of the heat exchange assembly can be stopped and reflected under the action of the air guide pieces extending in a zigzag manner when it propagates to the sound insulation cover, thereby reducing the noise of the heat exchange assembly propagating outward and improving the operating environment of the heat exchange assembly.

[0008] In addition, the heat exchange assembly according to the present application can also have the following additional technical features:

[0009] In some embodiments of the present application, the air guide member comprises a multi-section structure, so that the air flow flows along the multi-section structure from the air flow inlet of the ventilation gap to the air flow outlet of the ventilation gap, and the air flow path is longer than the straight-line distance from the air flow inlet to the air flow outlet. The air guide member is arranged in a multi-section structure, so that the air guide member extends tortuously from the air flow inlet to the air flow outlet, thereby lengthening the air flow path, increasing the noise reduction area and path, and thus facilitating the reduction of noise transmitted outward by the heat exchange assembly and improving the operating environment of the heat exchange assembly.

[0010] In some embodiments of the present application, the air guide member comprises a first air guide part and a second air guide part, and the first air guide part is connected at an obtuse angle with the second air guide part in the second direction. The first air guide part and the second air guide part of the air guide member are connected at an obtuse angle, and when the air flow flows from the first air guide part to the second air guide part, the flow direction changes relatively gently, which can reduce the flow resistance, and at the same time, a better noise reduction effect can be achieved.

[0011] In some embodiments of the present application, the air guide member further comprises a third air guide part, and the first air guide part, the second air guide part and the third air guide part are sequentially connected at an obtuse angle in the second direction. The first air guide part, the second air guide part and the third air guide part of the air guide member are connected at an obtuse angle, and when the air flow flows through the air guide member, the flow direction changes relatively gently, which can reduce the flow resistance, and at the same time, the noise is reflected and stopped multiple times, so that the heat exchange assembly has a better noise reduction effect.

[0012] In some embodiments of the present application, the first air guide part and the third air guide part are arranged on the same side of the second air guide part. The first air guide part and the third air guide part are located on the same side of the second air guide part, and the first air guide part, the second air guide part and the third air guide part form a semi-enclosed structure. The noise reflected by the first air guide part, the second air guide part and the third air guide part can be reflected multiple times in the semi-enclosed structure for noise reduction. In particular, the first air guide part and the third air guide part can be inclined relative to each other. The noise entering the ventilation gap is reflected by the third air guide part and then impacts the first air guide part, and is reflected again by the first air guide part to the third air guide part. The noise can be reflected multiple times for noise reduction, thereby improving the noise reduction effect of the heat exchange assembly.

[0013] In some embodiments of the present application, in the first direction, the first air guide part and the third air guide part are arranged to be inclined downward relative to the second air guide part. Such an air guide member can improve the drainage performance of the air guide member.

At the same time, the air guide base serves as a fixed shape support and is not easy to be damaged, so that it can be used for a long time. When the air guide member is used for a long time and the noise reduction effect is reduced, the sound absorbing component can be replaced, so that the air guide member can maintain good noise reduction effect, and the operation is convenient and the replacement cost is low. In addition, the sound absorbing component is exposed, the air guide base can not be provided with micropores in communication with the sound absorbing component, the air guide base can better reflect and stop the noise, and the noise reduction effect can be further improved.

By arranging the drainage holes, the accumulated water in the sound absorption member can be drained in a timely manner.

In this embodiment, the air deflectors are fixed with the guide positioning portions through the fasteners, which is convenient to operate and simple in structure. In the case that the guide positioning portions are designed to be detachable, the plurality of air deflectors can be adjusted in distance as needed, assembled to the guide positioning portions offline, and then assembled to the coaming as a whole. The distance adjustment does not need to be performed on the whole machine, which is convenient and labor-saving to operate.

For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0073] A battery can store electrical energy and power a power consuming device. With the development of new energy, energy storage devices with batteries are gradually widely used due to their large electrical energy storage capacity. The energy storage device can include a cabinet body, and the battery is arranged in the cabinet body. The number of batteries is usually multiple.

[0074] Temperature has a great influence on the performance of the battery. Too low temperature will reduce the activity of the battery and may cause the battery to be unable to charge and discharge. Too high temperature will have the risk of causing thermal runaway. The energy storage device is usually configured with a thermal management system to regulate the temperature of the battery in the energy storage device.

[0075] In some energy storage devices, the thermal management system regulates the temperature of the battery through a refrigerant heat exchange device, for example, a water chiller can be used to cool the battery in cooperation with a corresponding device. The refrigerant heat exchange device generally includes a compressor, a condenser, a throttling component and an evaporator connected through a refrigerant pipeline. Taking the cooling of the battery as an example, the evaporator is used for heat exchange with the battery to reduce the temperature of the battery, for example, the evaporator can be directly in contact with the battery for heat exchange, and for another example, the evaporator can exchange heat with the environment where the battery is located, or the evaporator can exchange heat with the cooling water system connected to the battery to cool the battery through the cooling water system; the condenser is used for heat exchange with air. In order to improve the refrigeration effect, the condenser is usually provided with an air flow guiding mechanism such as a fan, which can accelerate the flow of air flow to improve the heat exchange efficiency between the condenser and the air flow (formed by air). Among them, the air flow guiding mechanism guides the flow of air flow, not only needs to absorb the heat generated at the end of the battery, and dissipate the heat to the outside, but also needs to dissipate the heat generated by the refrigerant heat exchange device itself (such as the work of the compressor), so the air volume demand of the air flow guiding mechanism is large, the operating power of the air flow guiding mechanism is increased, and the noise of the operation of the air flow guiding mechanism and the noise formed by the flow of air flow are large.

[0076] How to reduce the noise of the refrigerant heat exchange equipment, so that the energy storage device has a better operating environment, has always been the focus of the research and development of the energy storage device. It is found that the noise generated by the airflow guiding mechanism during operation can be transmitted outward through the corresponding air vent of the airflow guiding mechanism. For example, the airflow guiding mechanism is arranged at the air outlet of the shell of the refrigerant heat exchange equipment, and the noise generated by the airflow guiding mechanism and the like will be transmitted outward through the air outlet, making it difficult to reduce the noise.

[0077] In view of the problem that the noise of the refrigerant heat exchange equipment is transmitted outward through the air vent, making it difficult to reduce the noise, the present application provides a heat exchange equipment, a soundproof cover is arranged at the air vent where the airflow guiding mechanism is located, the soundproof cover is provided with a ventilation structure, and the air guide member of the ventilation structure is bent and / or folded.

[0078] When the noise generated by the airflow guiding mechanism is transmitted outward through the air vent, the soundproof cover can play a certain noise isolation and reduction effect on the noise. At the same time, the air guide member is bent and / or folded, which can reduce the wind speed by changing the wind direction, thereby reducing the noise generated by airflow, and also can make the noise be reflected and attenuated at the bending or folding part of the air guide member, thereby reducing the noise transmitted to the outside and improving the control ability of the noise.

[0079] It should be noted that other noises generated by the heat exchange equipment, such as the noise generated by the airflow passing through the first heat exchanger, can also be reduced by the soundproof cover when transmitted outward through the air vent.

[0080] The heat exchange equipment of the present application can be applied to a cold water machine, and the first heat exchanger can be a condenser of the cold water machine. The cold water machine using the heat exchange equipment of the present application can reduce the noise transmitted outward at the air outlet, thereby improving the overall noise problem of the cold water machine.

[0081] The heat exchange assembly or heat exchange equipment proposed in the present application or any embodiment of the present application can be applied to an energy storage device to regulate the temperature of the battery in the energy storage device. For example, the heat exchange equipment can form a battery thermal management system in combination with a cooling medium circulating device, and exchange heat with the battery through the cooling medium circulating device. For another example, the heat exchange equipment can be used independently to exchange heat directly with the battery in the energy storage device, or exchange heat directly with the air in the cabinet of the energy storage device to reduce the temperature in the cabinet. The heat exchange equipment proposed in the present application or any embodiment of the present application can also be used in an electric device to regulate the temperature of the battery of the electric device.

Of course, the battery 12 can also be in the form of a battery module in which multiple battery cells are connected in series, connected in parallel, or connected in a mixed manner, and then multiple battery modules are connected in series, connected in parallel, or connected in a mixed manner to form a whole, and then the whole is accommodated in the box body.

[0087] Fig. 3 is a schematic diagram of a heat management system according to some embodiments of the present application. As shown in Fig. 3, the heat management system 14 can include a first heat exchange circuit 100 and a second heat exchange circuit 200. The second heat exchange circuit 200 is configured to exchange heat with the battery 12. The first heat exchange circuit 100 is configured to exchange heat with the second heat exchange circuit 200.

The heat exchange device 101 can include, in series, a compressor 150, a first heat exchanger 120, a throttling component 160, and a second heat exchanger 180. The second heat exchange circuit 200 can include a cooling medium circulation device.

[0089] The cabinet 11 can include a receiving space 15 on one side of the bracket 13. The heat exchange device 101 can be installed in the receiving space 15. Alternatively, the heat exchange device 101 can be installed outside the cabinet 11 of the energy storage device 10. As shown in Figs. 4 and 5, the heat exchange device 101 can further include a housing 110. The compressor 150, the first heat exchanger 120, the throttling component 160, and the second heat exchanger 180 can be installed in the housing 110. Alternatively, some of the components of the heat exchange device 101 can be installed in the housing 110, and some of the components of the heat exchange device 101 can be installed outside the housing 110. Alternatively, when the heat exchange device 101 is installed outside the cabinet 11, the first heat exchanger 120 and the air flow guiding mechanism 130 can be installed in the housing 110. Alternatively, the compressor 150 can be installed in the housing 110 outside the cabinet 11. Alternatively, all the components of the heat exchange device 101 can be installed in the housing 110 outside the cabinet 11.

[0090] The housing 110 can include an air inlet and an air outlet. The air inlet is configured to allow air to flow into the housing 110. The air outlet is configured to allow air to flow out of the housing 110. The housing 110 can be installed in the receiving space 15. The cabinet 11 can include a communication port. The communication port is configured to allow the air outlet and the air inlet of the housing 110 to communicate with the outside of the cabinet 11. The communication port can include a mesh structure.

[0091] The first heat exchanger 120 can be used for heat exchange with air, i.e., heat exchange with the environment. The second heat exchanger 180 is used for heat exchange with the cooling medium in the second heat exchange circuit 200. One of the first heat exchanger 120 and the second heat exchanger 180 acts as a condenser, and the other acts as an evaporator. Specifically, in the case where the battery 12 needs to be heated to increase the temperature of the battery 12, the first heat exchanger 120 is used as an evaporator, and the second heat exchanger 180 is used as a condenser; in the case where the battery 12 needs to be cooled to reduce the temperature of the battery 12, the first heat exchanger 120 is used as a condenser, and the second heat exchanger 180 is used as an evaporator. The heat exchange device 101 can also be provided with a corresponding valve control assembly, so that the first heat exchanger 120 and the second heat exchanger 180 are switched under different working conditions.

[0092] The compressor 150 is a driven fluid machine that lifts low-pressure gas to high-pressure gas. It sucks in low-temperature and low-pressure refrigerant from its refrigerant inlet, compresses it by driving the piston through the motor, and discharges high-temperature and high-pressure refrigerant to its refrigerant outlet, providing power for the refrigerant circulation. Refrigerant, also known as refrigerant, snow species, etc., is a medium substance used to complete energy conversion in various heat engines.

[0093] The first heat exchanger 120 is provided with a refrigerant passage for the refrigerant to flow through. When the refrigerant flows through the first heat exchanger 120, it can exchange heat with the air outside the first heat exchanger 120. As shown in FIG. 3, in order to improve the heat exchange efficiency of the first heat exchanger 120 and the air, the heat exchange device 101 can also be provided with an air flow guiding mechanism 130, which can be used to guide the air flow through the first heat exchanger 120. The air flow guiding mechanism 130 can be a fan, specifically an axial fan, a mixed flow fan, etc. Among them, the mixed flow fan is also called a mixed flow fan, which is a fan between the axial fan and the centrifugal fan. The impeller of the mixed flow fan makes the air do both centrifugal and axial motion, and the motion of the air is a mixture of axial and centrifugal motion.

[0094] The second heat exchanger 180 is provided with a refrigerant passage for the refrigerant to flow through. When the refrigerant flows through the second heat exchanger 180, the refrigerant can exchange heat with the cooling medium in the second heat exchanger 180. The position of the second heat exchanger 180 can correspond to the first medium containing part, and the first medium containing part is in communication with the second heat exchange circuit 200, and the refrigerant in the second heat exchanger 180 exchanges heat with the cooling medium in the first medium containing part. Optionally, in some embodiments, the second heat exchanger 180 is provided with a medium passage, which can be used as the first medium containing part, and the inlet and outlet of the medium passage are in communication with the outlet and inlet of the second heat exchange circuit 200 respectively to form a circulation loop of the cooling medium. The medium passage and the refrigerant passage are independent of each other, and the cooling medium in the medium passage exchanges heat with the refrigerant to realize heat exchange between the second heat exchanger 180 and the cooling medium. Optionally, in another embodiment, the first medium containing part can be a liquid storage tank, a liquid storage tank, a communication pipe, etc., and the second heat exchanger 180 can be arranged in the first medium containing part, and the refrigerant in the second heat exchanger 180 exchanges heat with the cooling medium in the first medium containing part. The first heat exchanger 120 and the second heat exchanger 180 can be plate heat exchangers, fin heat exchangers, etc.

[0095] The second heat exchange circuit 200 includes a circulation pipeline 220 and a heat exchange member 210. The heat exchange member 210 is a member that can conduct heat, which can be a water cooling plate. The cooling medium exchanges heat with the battery 12 through the heat exchange member 210. The heat exchange member 210 can be arranged outside the battery 12 and can be arranged in close contact with the battery 12 to facilitate heat exchange between the battery 12 and the heat exchange member 210. The heat exchange member 210 can also be arranged inside the battery 12, for example, between adjacent battery cells in the battery 12. The heat exchange member 210 can also be part of the box of the battery 12, i.e., part of the box as the heat exchange member 210.

[0096] The heat exchange member 210 is provided with a medium passage, and the inlet and outlet of the medium passage of the heat exchange member 210 are connected with the circulation pipeline 220. The circulation pipeline 220 can be provided with a driving assembly 230 for driving the cooling medium to flow from the corresponding first medium containing part of the second heat exchanger 180 to the heat exchange member 210, and then back to the corresponding first medium containing part of the second heat exchanger 180 through the heat exchange member 210. The cooling medium can be a liquid such as water, etc., and can also be a gas or other flowable substance.

[0097] The throttling assembly 160 is used to throttle the refrigerant to change the pressure, which can function to throttle and adjust the flow. The throttling assembly 160 can be an expansion valve.

[0098] Referring to FIG. 3, in some embodiments, the first heat exchanger 120 of the heat exchange device 101 is used as a condenser, and the second heat exchanger 180 is used as an evaporator, i.e., the refrigerant pipeline 190 is sequentially connected in series with the compressor 150, the first heat exchanger 120, the throttling assembly 160, and the second heat exchanger 180 to form a refrigerant loop (the present embodiment is mainly described by taking the refrigerant loop as a cooling loop), which can be used for refrigeration, e.g., as a part of a water chiller. The general working principle of the heat exchange device 101 for refrigeration is as follows: the second heat exchanger 180 of the refrigerant loop exchanges heat with the cooling medium of the second heat exchange loop 200, the cooling medium of the second heat exchange loop 200 passes through the heat exchange member 210 outside the battery to absorb the heat generated by the battery 12, the temperature of the cooling medium is increased, and the cooling medium enters the second heat exchanger 180. The cooling medium exchanges heat with the refrigerant evaporated in the second heat exchanger 180, and the refrigerant after evaporation absorbs heat. The refrigerant after evaporation is driven back to the compressor 150 in the refrigerant loop for compression to form a high-temperature and high-pressure state, and then passes through the condenser (the first heat exchanger 120) for condensation to form a medium-temperature and high-pressure state. The condenser (the first heat exchanger 120) dissipates the generated heat to the environment through the fan (air flow guiding mechanism 130), and the medium-temperature and high-pressure state refrigerant passes through the expansion valve (throttling assembly 160) to form a low-temperature and low-pressure two-phase state refrigerant, and then returns to the second heat exchanger 180 to form a cycle.

[0099] Continuing to refer to FIG. 3, the heat exchange device 101 can further be provided with a heating assembly 300. The heating assembly 300 can heat the cooling medium. The circulation pipeline 220 is in communication with the heating assembly 300, and the heating assembly 300 can be started when heating of the battery 12 is required. The heating assembly 300 can include an electric heating member and a second medium containing member. The second medium containing member can be a pipe, a tank, a box, etc., which can be connected in the circulation pipeline 220. The electric heating member is arranged in the second medium containing member to heat the cooling medium in the second medium containing member. The electric heating member can be a PTC heating body. PTC heating body, also called PTC heater, is a kind of electric heater using PTC material. The PTC heating body can be composed of a PTC ceramic heating element and an aluminum pipe. The PTC heating body has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant temperature and power saving electric heater.

[0100] It should be noted that the scheme of arranging the heating assembly 300 in the heat exchange device 101 can be combined with the scheme of the refrigerant circuit of the heat exchange device 101 for refrigeration. The second medium containing part of the heating assembly 300 is arranged in parallel with the first medium containing part corresponding to the second heat exchanger 180 in the circulation pipeline 220. In some implementations, when the heat exchange device 101 is in use, the second medium containing part of the heating assembly 300 and the second heat exchanger 180 and the second heat exchange circuit 200 can be selectively connected to the circulation pipeline 220. Specifically, this can be achieved by arranging a valve control assembly (such as a switch proportional valve, an electromagnetic valve, etc.) on the circulation pipeline 220, that is, when it is necessary to heat the battery 12, the refrigerant circuit formed by the compressor 150, the first heat exchanger 120, the throttling assembly 160, and the second heat exchanger 180 is started, the circulation pipeline 220 is connected to the first medium containing part corresponding to the second heat exchanger 180, the heating assembly 300 is closed, and the circulation pipeline 220 is disconnected from the first medium containing part of the heating assembly 300, and the second heat exchange circuit 200 delivers the cooling medium heat-exchanged by the second heat exchanger 180 to the heat exchange part 210 corresponding to the battery 12 to cool the battery 12, and the cooling medium is delivered back to the second heat exchanger 180 after passing through the heat exchange part 210; when it is necessary to cool the battery 12, the refrigerant circuit formed by the compressor 150, the first heat exchanger 120, the throttling assembly 160, and the second heat exchanger 180 is stopped, the circulation pipeline 220 is disconnected from the first medium containing part corresponding to the second heat exchanger 180, the heating assembly 300 is opened, and the circulation pipeline 220 is connected to the second medium containing part of the heating assembly 300, and the second heat exchange circuit 200 delivers the cooling medium heated by the heating assembly 300 to the heat exchange part 210 corresponding to the battery 12 to heat the battery 12, and the cooling medium is delivered back to the heating assembly 300 after passing through the heat exchange part 210. In other implementations, when the heat exchange device 101 is in use, the second medium containing part of the heating assembly 300 and the second heat exchanger 180 and the second heat exchange circuit 200 can also be connected to the circulation pipeline 220, and when it is necessary to heat the battery 12, the refrigerant circuit formed by the compressor 150, the first heat exchanger 120, the throttling assembly 160, and the second heat exchanger 180 is started, the heating assembly 300 is closed, and when it is necessary to cool the battery 12, the refrigerant circuit formed by the compressor 150, the first heat exchanger 120, the throttling assembly 160, and the second heat exchanger 180 is stopped, and the heating assembly 300 is opened.

[0101] It should be further explained that the heat management system 14 of the embodiment can also include temperature sensors and the like. For example, a temperature sensor can be arranged on the battery 12 to detect the temperature of the battery 12; a temperature sensor can be arranged in the cabinet 11 in which the battery 12 is located to detect the temperature in the cabinet 11 in which the battery 12 is located; and a temperature sensor can be arranged outside the cabinet 11 to detect the temperature of the external environment. The second heat exchange circuit can be provided with a temperature sensor and a pressure sensor to detect the temperature and flow pressure of the refrigerant, and the second heat exchange circuit can also be provided with a temperature sensor and a pressure sensor to detect the temperature and flow pressure of the cooling medium. The energy storage device 10 can perform adaptive control on the heat exchange device 101 based on the detected temperature of the temperature sensors and the like to adjust the temperature of the battery 12. Specifically, the operation control of the heat exchange device 101 can be performed by the controller of the energy storage device 10, or a separate controller can be arranged in the heat management system 14, and the separate controller can perform operation control on the heat exchange device 101.

[0102] Referring to FIGS. 4 and 5, and in combination with FIGS. 6 to 8, FIG. 6 is a structural schematic diagram of a heat exchange assembly according to some embodiments of the present application, FIG. 7 is a structural schematic diagram of a soundproof cover 140 according to some embodiments of the present application, and FIG. 8 is a sectional view of the soundproof cover 140 according to some embodiments of the present application. The present embodiment provides a heat exchange assembly, which includes a housing 110, a first heat exchanger 120, an airflow guiding mechanism 130, and a soundproof cover 140. The housing 110 has a receiving cavity and a first wall 111 surrounding the receiving cavity, and the first wall 111 is provided with a first air vent 113 communicating with the receiving cavity. The first heat exchanger 120 is arranged in the receiving cavity and is used to exchange heat with external airflow. The airflow guiding mechanism 130 is arranged at the first air vent 113 and is used to guide the airflow to flow through the first heat exchanger 120. The soundproof cover 140 is arranged to connect the first wall 111 and surround the first air vent 113 and the airflow guiding mechanism 130. The soundproof cover 140 includes a ventilation structure 142 arranged corresponding to the first wall 111, and the ventilation structure 142 includes a plurality of air guide pieces 143 arranged at intervals along a first direction Z, and the adjacent air guide pieces 143 have ventilation gaps 1436 therebetween. Each air guide piece 143 is arranged to extend in a second direction Y in a zigzag manner, and the first direction Z intersects the second direction Y.

[0103] The shell 110 is an internally hollow member, and the space in the middle of the interior forms a receiving cavity, which can be processed according to requirements. The first ventilation port 113 is connected with the outside of the shell 110 and the interior of the shell 110 through the ventilation gap 1436 of the sound insulation cover 140. The first ventilation port 113 can serve as an air inlet of the shell 110 or an air outlet of the shell 110. The shell 110 is further provided with a second ventilation port 112, which is connected with the outside and the interior of the shell 110. In some implementations, the airflow guiding mechanism 130 can be configured to blow air, i.e., to guide the airflow to flow from the ventilation gap 1436 of the sound insulation cover 140, through the first ventilation port 113, the first heat exchanger 120, and then out through the second ventilation port 112. In this case, the first ventilation port 113 serves as the air inlet of the shell 110, and the second ventilation port 112 can serve as the air outlet of the shell 110. In other implementations, the airflow guiding mechanism 130 can be configured to suck air, i.e., to guide the airflow to flow from the second ventilation port 112, through the first heat exchanger 120, and then to the outside through the first ventilation port 113 and the ventilation gap 1436 of the sound insulation cover 140. In this case, the second ventilation port 112 serves as the air inlet of the shell 110, and the first ventilation port 113 serves as the air outlet of the shell 110. The airflow can be air.

[0104] The first wall 111 is a wall of the shell 110 provided with the first ventilation port 113. The first wall 111 can be part of the outer wall of the shell 110. The first ventilation port 113 can be provided on any wall of the shell 110, such as the top wall, the side wall, or the bottom wall of the shell 110. The second ventilation port 112 and the first ventilation port 113 can be provided on different walls of the shell 110 to reduce the mutual influence between the air inlet and the air outlet and improve the heat exchange effect of the heat exchange assembly. The first ventilation port 113 can also be provided on the same side wall as the second ventilation port 112. In this case, the second ventilation port 112 and the first ventilation port 113 can be spaced apart to reduce the mutual influence between the air inlet and the air outlet. One or more first ventilation ports 113 and one or more second ventilation ports 112 can be provided on the shell 110.

[0105] The airflow guiding mechanism 130 can be a blower, an axial flow fan, or a mixed flow fan (inclined flow fan, etc.). The airflow guiding mechanism 130 can be mounted and fixed to the first wall 111. Alternatively, the airflow guiding mechanism 130 can be entirely provided on the outer wall surface of the first wall 111 and directly opposite the first ventilation port 113. One end of the airflow guiding mechanism 130 is connected and communicated with the first ventilation port 113, and the other end of the airflow guiding mechanism 130 is communicated with the outside through the opening of the sound absorption cavity. Alternatively, the airflow guiding mechanism 130 can also be partially provided in the first ventilation port 113 and partially protrude from the outer wall surface. The airflow guiding mechanism 130 can also partially protrude from the inner wall surface of the first wall 111 and be provided in the receiving cavity.

[0106] The first heat exchanger 120 can be a refrigerant heat exchanger, and a refrigerant channel can be arranged in the first heat exchanger 120. The external airflow refers to the airflow formed by the air outside the first heat exchanger 120. The external airflow (i.e., the air) can flow through the outer surface of the first heat exchanger 120 and can exchange heat with the refrigerant in the first heat exchanger 120 through the first heat exchanger 120. The first heat exchanger 120 can be a parallel flow heat exchanger, a flat plate heat exchanger, a fin heat exchanger, a micro-channel heat exchanger, or the like. The first heat exchanger 120 is arranged in the accommodation cavity of the shell 110 and can be fixedly connected with the shell 110 by a support, a fixing member (e.g., a bolt, etc.), or the like. The first heat exchanger 120 is located on the airflow flow path between the first vent 113 and the second vent 112, so that the airflow guiding mechanism 130 can guide the flowing airflow to flow through the first heat exchanger 120.

[0107] It should be noted that, for the convenience of understanding other components, only a part of the top end and the bottom end of the first heat exchanger 120 is shown in FIG. 4, and actually the first heat exchanger 120 is an integral structure from the top end to the bottom end.

[0108] The soundproof cover 140 can be arranged outside the first wall 111, that is, the soundproof cover 140 is arranged on the side of the first wall 111 away from the accommodation cavity. The soundproof cover 140 can be arranged outside the periphery of the airflow guiding mechanism 130 and the first vent 113, and can be annularly arranged in one circle, and can be substantially rectangular, or can be substantially circular, elliptical, or other shapes. The soundproof cover 140 can be fixedly connected with the first wall 111 by welding, bolt connection, or the like.

[0109] The vent structure 142 forms a vent of the soundproof cover 140, and the vent gap 1436 of the vent structure 142 communicates the inside and outside of the soundproof cover 140. The airflow can enter or exit the soundproof cover 140 from the vent gap 1436. Specifically, when the airflow guiding mechanism 130 guides the airflow to enter the accommodation cavity of the shell 110 from the soundproof cover 140, the vent structure 142 is an air inlet structure; when the airflow guiding mechanism 130 guides the airflow to exit the accommodation cavity of the shell 110 through the soundproof cover 140, the vent structure 142 is an air outlet structure.

[0110] The first direction Z can be any direction substantially parallel to the wall surface of the first wall 111, for example, the first direction Z can be the height direction of the first wall 111 (which can be understood with reference to the vertical direction of FIGS. 6 and 7), or the first direction Z can be the width direction of the first wall 111 (which can be understood with reference to the third direction X of the first wall 111 of FIG. 7). The second direction Y can be the arrangement direction of the first wall 111 to the soundproof cover 140, which can be understood with reference to the direction of the first wall 111 towards the soundproof cover 140, and is substantially consistent with the axis direction of the first air vent 113 and substantially perpendicular to the wall surface of the first wall 111. Alternatively, the second direction Y can also be another direction intersecting the first direction Z.

[0111] The air guide 143 can be a plate structure, and the plate surface of the air guide 143 is arranged to extend in a zigzag manner along the second direction Y. The air guide 143 can be designed to be curved in an arc shape, or can be designed to be bent at an angle (greater than zero and less than 180 degrees). The air guide 143 can be designed to be curved in an arc shape along the second direction Y, or can be designed to be bent at an angle.

[0112] As shown in FIGS. 7 and 8, the zigzag fluctuation direction of the air guide 143 (i.e., the concave-convex direction of the air guide 143) can be consistent with the first direction Z, that is, the air guide 143 fluctuates in the first direction Z, that is, the air guide 143 is concave or convex in the first direction Z, so that the air guide 143 extends in a zigzag manner along the second direction Y. Alternatively, the zigzag fluctuation direction of the air guide 143 (i.e., the concave-convex direction of the air guide 143) can be consistent with the third direction X, that is, the air guide 143 fluctuates in the third direction X, that is, the air guide 143 is concave or convex in the third direction X, so that the air guide 143 extends in a zigzag manner along the second direction Y. Of course, the air guide 143 can be designed to fluctuate in both the first direction Z and the third direction X. The third direction X is a direction intersecting both the first direction Z and the second direction Y.

[0113] The size of the ventilation gap 1436 between the same group of two adjacent air guides 143 along the first direction Z can be substantially the same from the first end to the second end of the second direction Y, or can be designed to be different, for example, the size of the ventilation gap 1436 gradually decreases along the second direction Y. The size of the plurality of ventilation gaps 1436 along the first direction Z can be the same or different. The fluctuation bending direction of the plurality of air guides 143 can be the same or different, and the plurality of air guides 143 can be the same bending shape or different bending shapes.

[0114] In one specific embodiment, as shown in FIGS. 7-8, optionally, the first direction Z is a height direction of the first wall 111 (i.e., a vertical direction of the shell 110), the third direction X is a width direction of the first wall 111, and the second direction Y is a direction perpendicular to the wall surface of the first wall 111 (i.e., a thickness direction of the shell 110), the first direction Z, the second direction Y, and the third direction X are substantially perpendicular to each other, the air guide members 143 are arranged at intervals along the first direction Z, each air guide member 143 extends in a zigzag manner along the second direction Y and is curved in the first direction Z, the air guide members 143 are substantially linear along the third direction X, and the plurality of air guide members 143 form a louver-like ventilation structure 142. The ventilation gaps 1436 between the two adjacent air guide members 143 in the same group have a substantially same size along the first direction Z, and the plurality of air guide members 143 have a same shape.

[0115] The ventilation structure 142 of the soundproof cover 140 can meet the air intake and exhaust requirements of the equipment, and when the noise generated by the airflow guiding mechanism 130 and other noises propagate to the soundproof cover 140, the soundproof cover 140 can isolate and reduce the noise to a certain extent. In addition, the air guide members 143 are arranged in a zigzag manner, which can reduce the noise generated by airflow by changing the airflow direction and reducing the airflow speed, and the noise can be repeatedly blocked and reflected at the curved or bent portions of the air guide members 143, thereby attenuating the noise and reducing the noise propagation to the outside, thereby improving the noise control capability.

[0116] According to some embodiments of the present application, optionally, the air guide member 143 comprises a multi-segment structure, so that the airflow flows along the multi-segment structure from the airflow inlet of the ventilation gap to the airflow outlet of the ventilation gap, and the airflow path is longer than the straight-line distance from the airflow inlet to the airflow outlet.

[0117] The airflow path is the actual flow path of the airflow, that is, the path of the airflow flowing from the airflow inlet to the airflow outlet through the surface of the multi-segment structure. The airflow path is longer than the straight-line distance from the airflow inlet to the airflow outlet, which means that the multi-segment structure of the air guide member extends in a zigzag manner, and the airflow flows along a curved or zigzag path, so that the actual flow path of the airflow is longer than the straight-line distance from the airflow inlet to the airflow outlet.

[0118] It should be noted that in the present embodiment, the airflow inlet to airflow outlet direction can be substantially understood with reference to the second direction Y.

[0119] The air guide member 143 is arranged in a multi-segment structure, so that the air guide member extends in a zigzag manner along the airflow inlet to the airflow outlet. The multi-segment structure lengthens the airflow path and increases the noise reduction area, thereby facilitating the reduction of noise propagated outward by the heat exchange assembly and improving the operating environment of the heat exchange assembly.

[0120] According to some embodiments of the present application, as shown in FIG. 8, the air guide 143 includes a first air guide part 1431 and a second air guide part 1432, and the first air guide part 1431 is connected to the second air guide part 1432 at an obtuse angle along the second direction Y.

[0121] The first air guide part 1431 and the second air guide part 1432 can each be a plate-shaped structure. The first air guide part 1431 and the second air guide part 1432 are sequentially arranged along the second direction Y, and one end of the first air guide part 1431 is connected to one end of the second air guide part 1432. The first air guide part 1431 and the second air guide part 1432 can be an integral structure, for example, the first air guide part 1431 and the second air guide part 1432 are formed by bending a mold plate, or the first air guide part 1431 and the second air guide part 1432 can be an integral structure connected by welding or the like. The first air guide part 1431 and the second air guide part 1432 can be connected by an arc-shaped transition, or can be directly connected by a straight bending.

[0122] The angle between the first air guide part 1431 and the second air guide part 1432 can be 95 degrees, 100 degrees, 110 degrees, 120 degrees, 130 degrees, 140 degrees, 150 degrees, 160 degrees, etc. Considering the smoothness of air guiding and the noise reduction effect, the angle between the first air guide part 1431 and the second air guide part 1432 can be set to between 120 degrees and 150 degrees.

[0123] The first air guide part 1431 and the second air guide part 1432 can each extend substantially linearly along the third direction X. The plurality of air guides 143 can all be structures including the first air guide part 1431 and the second air guide part 1432, the first air guide parts 1431 of the plurality of air guides 143 can be arranged in parallel, the second air guide parts 1432 of the plurality of air guides 143 can be arranged in parallel with each other, and the first air guide part 1431 and the second air guide part 1432 of the plurality of air guides 143 form a ventilation gap 1436 that communicates with each other between two adjacent first air guide parts 1431 along the first direction Z and between two adjacent second air guide parts 1432.

[0124] In the present embodiment, the first air guide part 1431 and the second air guide part 1432 of the air guide 143 are connected at an obtuse angle, and when the airflow flows from the first air guide part 1431 to the second air guide part 1432, the flow direction changes relatively gently, which can reduce the flow resistance, and at the same time, a better noise reduction effect can be achieved.

[0125] It should be noted that along the second direction Y, the air guide 143 can only have one bending part, i.e., the first air guide part 1431 and the second air guide part 1432 constitute the air guide 143. Alternatively, the air guide 143 can further include other air guide parts based on the first air guide part 1431 and the second air guide part 1432, and form multiple bending parts.

[0126] Continuing to refer to FIG. 8, according to some embodiments of the present application, optionally, in some implementations, the air guide 143 further comprises a third air guide portion 1433, and the first air guide portion 1431, the second air guide portion 1432 and the third air guide portion 1433 are sequentially connected at an obtuse angle along the second direction Y.

[0127] The first air guide portion 1431, the second air guide portion 1432 and the third air guide portion 1433 are sequentially arranged and connected along the second direction Y, and the first air guide portion 1431 and the second air guide portion 1432 form a bending position, and the connection position of the second air guide portion 1432 and the third air guide portion 1433 forms another bending position. The first air guide portion 1431, the second air guide portion 1432 and the third air guide portion 1433 can be an integral structure, for example, the first air guide portion 1431, the second air guide portion 1432 and the third air guide portion 1433 are formed by bending a mold plate, and optionally, the first air guide portion 1431, the second air guide portion 1432 and the third air guide portion 1433 can also be an integral structure connected by welding or the like. The first air guide portion 1431 and the second air guide portion 1432 can be connected by arc-shaped transition, or can be directly connected by straight bending; the second air guide portion 1432 and the third air guide portion 1433 can be connected by arc-shaped transition, or can be directly connected by straight bending.

[0128] As shown in FIG. 8, the first air guide portion 1431 and the third air guide portion 1433 can be arranged on the same side of the second air guide portion 1432, that is, the two ends of the second air guide portion 1432 are bent to form the first air guide portion 1431 and the third air guide portion 1433 towards the same side. Optionally, the first air guide portion 1431 and the third air guide portion 1433 can also be arranged on different sides of the second air guide portion 1432, that is, the two ends of the second air guide portion 1432 are bent to form the first air guide portion 1431 and the second air guide portion 1432 towards different sides.

[0129] It should be noted that the angle between the first air guide portion 1431 and the second air guide portion 1432 and the angle between the second air guide portion 1432 and the third air guide portion 1433 can be the same or different. The angle between the first air guide portion 1431 and the second air guide portion 1432 can be 95 degrees, 100 degrees, 110 degrees, 120 degrees, 130 degrees, 140 degrees, 150 degrees, 160 degrees, etc., and the angle between the second air guide portion 1432 and the third air guide portion 1433 can be 95 degrees, 100 degrees, 110 degrees, 120 degrees, 130 degrees, 140 degrees, 150 degrees, 160 degrees, etc. Considering the smoothness of air guiding and the noise reduction effect, the angle between the first air guide portion 1431 and the second air guide portion 1432 and the angle between the second air guide portion 1432 and the third air guide portion 1433 can be set to between 120 degrees and 150 degrees respectively.

[0130] The first air guide part 1431, the second air guide part 1432, and the third air guide part 1433 can all extend substantially linearly along the third direction X. The first air guide part 1431 of each of the plurality of air guide parts 143 can be arranged in parallel, the second air guide part 1432 of each of the plurality of air guide parts 143 can be arranged in parallel, and the third air guide part 1433 of each of the plurality of air guide parts 143 can be arranged in parallel. Along the first direction Z, the first air guide part 1431, the second air guide part 1432, and the third air guide part 1433 of each of the plurality of air guide parts 143 can be arranged in a staggered manner, and the first air guide part 1431, the second air guide part 1432, and the third air guide part 1433 of each of the plurality of air guide parts 143 can be arranged in a staggered manner along the second direction Y.

[0131] Optionally, in one specific embodiment, the first air guide part 1431, the second air guide part 1432, and the third air guide part 1433 are connected in sequence at obtuse angles, the first air guide part 1431 and the third air guide part 1433 are located on the same side of the second air guide part 1432, and the second air guide part 1432 is arranged symmetrically along the middle line of the second direction Y between the first air guide part 1431 and the third air guide part 1433.

[0132] In this embodiment, the first air guide part 1431, the second air guide part 1432, and the third air guide part 1433 of the air guide part 143 are connected at obtuse angles. When the airflow flows through the air guide part 143, the flow direction changes relatively gently, which can reduce the flow resistance. At the same time, the noise is reflected and blocked multiple times, so that the heat exchange assembly has a good noise reduction effect.

[0133] According to some embodiments of the present application, as shown in FIG. 8, the first air guide part 1431 and the third air guide part 1433 are arranged on the same side of the second air guide part 1432.

[0134] It can be understood that the first air guide part 1431 and the third air guide part 1433 are located on the same side of the second air guide part 1432, and the first air guide part 1431, the second air guide part 1432, and the third air guide part 1433 form a semi-enclosed structure. The noise reflected by the first air guide part 1431, the second air guide part 1432, and the third air guide part 1433 can be reflected multiple times in the semi-enclosed structure for noise reduction. In particular, the first air guide part 1431 and the third air guide part 1433 can be inclined relative to each other. The noise entering the ventilation gap 1436 is reflected by the third air guide part and then impacts the first air guide part 1431 again. The noise is reflected by the first air guide part 1431 to the third air guide part 1433 again. The noise can be reflected multiple times for noise reduction, thereby improving the noise reduction effect of the heat exchange assembly.

[0135] According to some embodiments of the present application, as shown in FIG. 8, along the first direction Z, the first air guide part 1431 and the third air guide part 1433 are arranged to be inclined downward relative to the second air guide part 1432.

[0136] That is, the first air guide part 1431 and the third air guide part 1433 can be arranged at the lower side of the second air guide part 1432, and the first air guide part 1431 and the third air guide part 1433 are arranged to be inclined downward.

[0137] The second air guide part 1432 of the heat exchange assembly in the embodiment is arranged at a higher position, and the accumulated water can be discharged downward through the first air guide part 1431 and the third air guide part 1433, so that the water drainage performance of the air guide part 143 can be improved, the heat island effect of the air guide part 143 can be reduced, the corrosion rate of the air guide part 143 can be reduced, and the service life of the air guide part 143 can be improved.

[0138] According to some embodiments of the present application, the air guide part 143 is arranged as a porous sound-absorbing part.

[0139] The porous sound-absorbing part refers to a part that is at least partially arranged to have a plurality of holes (generally micro-holes) on the surface and can reduce noise based on the holes. The reduction of noise by the porous sound-absorbing part is mainly based on three mechanisms of reflection, scattering and absorption of noise. Among them, the reflection mechanism refers to that when noise encounters the surface of the porous sound-absorbing part, part of the energy will be reflected back, and the surface with high reflectivity can effectively reduce the penetration of sound. The scattering mechanism refers to that the irregular shape of the surface of the porous sound-absorbing part can make the propagation direction of the noise more diverse, thereby reducing the reflection of noise on the material surface. The micro-holes and protrusions on the surface of the porous sound-absorbing part can play a scattering role, increase the contact area between noise and the material, and thus reduce the reflection and propagation of noise. The absorption mechanism refers to that when noise enters the porous sound-absorbing material through the holes, its energy will gradually dissipate due to internal molecular friction and heat conduction, thereby effectively absorbing the energy of noise. The porous sound-absorbing part can be sound-absorbing cotton, sound-absorbing board, etc., which has low cost and good noise reduction effect.

[0140] The air guide part 143 can be provided with the porous sound-absorbing component 1435 at all positions, for example, the air guide part 143 can be an air guide plate made of porous sound-absorbing material. Alternatively, the air guide part 143 can also be provided with porous sound-absorbing material at some positions, for example, the air guide part 143 includes an air guide base 1434 and a sound-absorbing component 1435 wrapped on the air guide base 1434. The sound-absorbing component 1435 can be sound-absorbing cotton, and the air guide base 1434 can be a closed metal plate such as a steel plate. The sound-absorbing cotton can be made of PP (polypropylene) and PET (polyethylene terephthalate) materials, and the surface of the sound-absorbing cotton can be wrapped with non-woven fabric to improve the hydrophobic and water drainage performance of the sound-absorbing cotton and reduce the possibility of corrosion of the sound-absorbing cotton. Alternatively, the sound-absorbing cotton can also be made of foamed neoprene rubber.

[0141] In this embodiment, the air guide 143 is a porous sound absorbing member, and the noise (including noise generated by the air flow guide mechanism 130 and noise generated by the air flow through the first heat exchanger 120) can be continuously reflected and absorbed by the air guide 143, thereby improving the noise reduction effect.

[0142] According to some embodiments of the present application, as shown in FIGS. 9 and 10, FIG. 9 is a cross-sectional view of the soundproof cover 140 according to some embodiments of the present application, and FIG. 10 is an enlarged view of portion D of FIG. 9. The air guide 143 includes an air guide base 1434 and a sound absorbing member 1435, and the sound absorbing member 1435 is arranged on the surface of the air guide base 1434.

[0143] The air guide base 1434 can be a plate structure with certain support strength, a fixed shape, and not easy to deform, and can be used to form a stable shape of the air guide 143. Specifically, the air guide base 1434 can be a metal plate or a hard plastic plate, etc. The sound absorbing member 1435 can be a porous sound absorbing component, which can be sound absorbing cotton, etc. Optionally, the sound absorbing member 1435 can be attached to the air guide base 1434 by using adhesive. The sound absorbing member 1435 can be attached to one side of the air guide base 1434, or sound absorbing members 1435 can be arranged on both sides of the air guide base 1434.

[0144] In some technologies, sound absorbing cotton can be built into a plate body, and the plate body is provided with micropores in communication with the inside. The air guide 143 of the heat exchange assembly of the present embodiment overcomes the technical prejudice and is different from the above-mentioned technologies. The sound absorbing member 1435 is arranged on the surface of the air guide base 1434, so that the sound absorbing member 1435 is exposed and can achieve better noise reduction effect. At the same time, the air guide base 1434 plays a supporting role in fixing the shape, and is not easy to be damaged and can be used for a long time. When the air guide 143 is used for a long time and the noise reduction effect is reduced, the sound absorbing member 1435 can be replaced, so that the air guide 143 can maintain good noise reduction effect, and the operation is convenient and the replacement cost is low. In addition, the sound absorbing member 1435 is exposed and naked, and the air guide base 1434 does not need to be provided with micropores in communication with the sound absorbing member 1435. The air guide base 1434 can better reflect and stop the noise, and the noise reduction effect can be further improved.

[0145] According to some embodiments of the present application, as shown in FIGS. 7, 9 and 10, and in combination with FIGS. 11 and 12, FIG. 11 is a structural schematic view of the air guide 143 according to some embodiments of the present application, and FIG. 12 is a structural schematic view of the air guide base 1434 according to some embodiments of the present application. The circumferential edge of the air guide base 1434 is provided with a stop portion 1437, and the stop portion 1437 stops the circumferential edge of the sound absorbing member 1435.

[0146] The stop portion 1437 can be arranged along the contour line of the air guide base body 1434, or can be arranged on the partial circumferential edge of the air guide base body 1434, for example, the stop portion 1437 can be arranged at intervals along the contour line of the air guide base body 1434. In some implementations, the air guide base body 1434 is provided with a stop portion 1437 at least at both ends in the second direction Y, and the stop portion 1437 is arranged in a strip-shaped flange along the third direction X.

[0147] The stop portion 1437 protrudes from the plate surface of the air guide base body 1434, and the stop portion 1437 is used to surround the circumferential outer side of the sound absorption member 1435. The stop portion 1437 can be an integral structure with the air guide base body 1434, for example, the stop portion 1437 can be a flange formed by folding the edge of the air guide base body 1434 to one side. Alternatively, the stop portion 1437 can also be a component connected to the air guide base body 1434 by welding, fusion, fasteners (screws, rivets), etc.

[0148] It can be understood that when the sound absorption member 1435 is arranged on one side of the plate surface of the air guide base body 1434, the circumferential edge of the air guide base body 1434 can only be provided with a stop portion 1437 on the side where the sound absorption member 1435 is arranged; when the sound absorption member 1435 is arranged on both sides of the plate surface of the air guide base body 1434, the circumferential edge of the air guide base body 1434 can be provided with a stop portion 1437 on both sides, and the stop portions 1437 on both sides can respectively cover the circumferential edges of the sound absorption members 1435 on both sides. The stop portions 1437 on both sides can be an integral structure or a separate structure.

[0149] The air guide 143 of the heat exchange assembly of the present embodiment is provided with a stop portion 1437, which can stop the airflow and reduce the possibility of the airflow entering the space between the sound absorption member 1435 and the air guide base body 1434 from the edge of the sound absorption member 1435, thereby reducing the possibility of the edge of the sound absorption member 1435 being raised. In addition, the sound absorption member 1435 is fixed by cooperating with the back glue through the stop portion 1437, which improves the connection stability of the sound absorption member 1435 and the air guide base body 1434. At the same time, as shown in FIGS. 6 and 7, the stop portion 1437 can protect the edge of the sound absorption member 1435 and reduce the aging and corrosion problems of the sound absorption member 1435 caused by sunlight, air, etc. In addition, the stop portion 1437 can also serve as a fixing portion for connecting the air guide base body 1434 and the surrounding plate 141, and the air guide base body 1434 can be arranged to be relatively thin. The stop portion 1437 can improve the connection convenience of the air guide base body 1434 and the surrounding plate 141, and specifically, the surrounding plate 141 can be fixedly connected to the stop portion 1437 by rivets, screws, etc.

[0150] According to some embodiments of the present application, and with reference to Figs. 6, 7, and 9-12, the air guide member 143 further comprises a cladding portion 1438, and the air guide base 1434 is cladded with the cladding portion 1438 at both ends thereof along the second direction Y. The cladding portion 1438 is arranged to at least partially cladding the sound absorbing member 1435.

[0151] The air guide base 1434 is provided with the cladding portion 1438 at both ends thereof along the second direction Y. The cladding portion 1438 can be connected to the stop portion 1437 at the corresponding position, and at least part of the cladding portion 1438 clads and presses against the side of the sound absorbing member 1435 away from the air guide base 1434. Alternatively, the cladding portion 1438 on one side of the plate surface of the air guide base 1434 can be formed by folding the stop portion 1437. Alternatively, as shown in Figs. 7, 9-13, Fig. 13 is a schematic view of the structure of the cladding portion 1438 according to some embodiments of the present application. When the sound absorbing member 1435 is arranged on both sides of the plate surface of the air guide base 1434, a U-shaped groove member can be used as the cladding portion 1438 to cladding the end surface of the air guide base 1434. The two side portions 14381 of the cladding portion 1438 clads and presses against the sound absorbing member 1435 on both sides, and the bottom surface 14382 of the cladding portion 1438 is connected to the stop portion 1437 to fix the cladding portion 1438.

[0152] It should be noted that in some other embodiments, the cladding portion 1438 can be directly sleeved and fixed to the sound absorbing member 1435. That is, the cladding portion 1438 can not be connected to the stop portion 1437, or the air guide base 1434 can be independently provided with the cladding portion 1438 without the stop portion 1437.

[0153] According to some embodiments of the present application, and with reference to Figs. 6, 7, and 9-12, the air guide member 143 further comprises a cladding portion 1438, and the air guide base 1434 is cladded with the cladding portion 1438 at both ends thereof along the second direction Y. The cladding portion 1438 is arranged to at least partially cladding the sound absorbing member 1435.

[0154] According to some embodiments of the present application, and with reference to Figs. 9-12, the ends of the air guide base 1434 along the second direction Y are arranged to be downwardly inclined. The stop portion 1437 and / or the cladding portion 1438 at the ends of the air guide base 1434 along the second direction Y are provided with a drainage hole (see the second drainage hole 1442).

[0155] The two ends of the air guide base 1434 along the second direction Y are both inclined structures with end faces on the bottom and body parts on top, so that rain and the like will flow downward along the two ends of the air guide base 1434, which is conducive to drainage. The stop portion 1437 is located at the bottom of the air guide base 1434, which is prone to water accumulation. By providing a drainage hole, the water accumulated in the sound absorption member 1435 can be promptly drained. The drainage hole is also a ventilation hole, which can improve the ventilation of the sound absorption member 1435, reduce the heat island effect of the sound absorption member 1435, and delay the possibility of corrosion and aging of the sound absorption member 1435.

[0156] Optionally, in the case where the cladding portion 1438 is provided, the cladding portion 1438 can also have a drainage hole, for example, the bottom surface 14382 of the cladding portion 1438 corresponding to the stop portion 1437 can be provided with a drainage hole (for understanding, refer to the second drainage hole 1442).

[0157] According to some embodiments of the present application, optionally, as shown in FIGS. 8 to 12, the air guide 143 is arranged to undulate and zigzag in the vertical direction, the second direction Y intersects the vertical direction, and the undulating low area of the air guide 143 is provided with a drainage hole; and / or, the bottom wall 1411 of the sound insulation cover 140 is provided with a drainage hole (for understanding, refer to the first drainage hole 1441).

[0158] In this embodiment, the sound insulation cover 140 can be arranged on the side wall of the shell 110, that is, one of the side walls of the shell 110 forms the first wall 111, and the sound insulation cover 140 is mounted on one side of the first wall 111. The arrangement direction of the first wall 111 to the sound insulation cover 140 (i.e., the second direction Y) is substantially horizontal. Optionally, the first direction Z can be arranged to coincide with the vertical direction, that is, the plurality of air guides 143 are arranged at intervals along the vertical direction. Naturally, the first direction Z can also be arranged to be substantially perpendicular to the second direction Y, that is, the horizontal direction.

[0159] The air guide 143 is arranged to undulate and zigzag in the vertical direction, which can be understood as that the air guide 143 is concave-convex in the vertical direction, so that the local position of the air guide 143 is higher than the positions on both sides thereof. The areas on both sides of the undulating low area of the sound insulation cover 140 are both higher than the undulating low area. In the case where the air guide 143 includes the air guide base 1434 and the sound insulation member, the air guide base 1434 forms the support of the air guide 143, and the air guide base 1434 can be provided with a drainage hole.

[0160] The bottom wall 1411 of the sound insulation cover 140 is the lowest wall surface of the sound insulation cover 140. Optionally, the bottom wall 1411 of the sound insulation cover 140 can be provided with a drainage hole, so that the water can be promptly drained from the sound insulation cover 140. The bottom wall 1411 of the sound insulation cover 140 can be a part of the surrounding plate 141, which can be connected to the first wall 111.

[0161] The water accumulated in the air guide 143 can be drained in time through the drainage hole, and the drainage hole is also a ventilation hole, which can improve the ventilation of the air guide 143, reduce the heat island effect of the air guide 143, and delay the corrosion and aging of the air guide 143.

[0162] According to some embodiments of the present application, the air guide 143 is optionally provided as a surface hydrophobic structure.

[0163] Optionally, the air guide 143 can be coated with a hydrophobic material to form a hydrophobic layer, so as to improve the water drainage capacity of the air guide 143 and reduce the possibility of damage to the air guide 143. When the air guide 143 includes a surface-exposed sound-absorbing member 1435, the surface of the sound-absorbing member 1435 can be provided as a hydrophobic structure to reduce the heat island effect of the sound-absorbing member 1435 and delay the corrosion and mildew of the sound-absorbing member 1435. Optionally, the sound-absorbing member 1435 includes sound-absorbing cotton, which can be made of a relatively hydrophobic material, such as foamed neoprene, to form a sound-absorbing member 1435 with a relatively hydrophobic surface. Optionally, the sound-absorbing member 1435 can also include sound-absorbing cotton and a hydrophobic mesh bag wrapped outside the sound-absorbing cotton. For example, the sound-absorbing cotton can be made of a material combining PP and PET, and the surface of the sound-absorbing cotton is wrapped with non-woven fabric to form a hydrophobic mesh bag. The dense holes of the non-woven fabric can allow noise to pass through, while the non-woven fabric has good hydrophobicity and corrosion resistance.

[0164] The air guide 143 is provided as a surface hydrophobic structure, which can drain the water accumulated on the air guide 143 in time, reduce the heat island effect of the air guide 143, and delay the corrosion and aging of the air guide 143.

[0165] According to some embodiments of the present application, as shown in FIGS. 6-8, the soundproof cover 140 further includes a surrounding plate 141 connected with the first wall 111, the surrounding plate 141 is arranged around the first ventilation opening 113 and the airflow guiding mechanism 130, and the ventilation structure 142 is arranged in the surrounding plate 141.

[0166] The surrounding plate 141 can be connected head to tail around the first ventilation opening 113 and the airflow guiding mechanism 130 to form a frame-shaped or cylindrical structure with both ends open. One end of the surrounding plate 141 is fixedly connected with the first wall 111, and the other end of the surrounding plate 141 is arranged away from the first wall 111. The ventilation structure 142 is arranged in the space surrounded by the surrounding plate 141, and the air guide 143 can be installed on the surrounding plate 141 and fixedly arranged by the surrounding plate 141. The surrounding plate 141 can also be a closed soundproof plate body, such as a steel plate. The surrounding plate 141 can be a sound-absorbing plate body with micropores, such as a plate body with rock wool, etc.

[0167] Optionally, the surrounding plate 141 can be detachably installed on the first wall 111 to facilitate replacement and disassembly of the soundproof cover 140.

[0168] In one specific implementation, as shown in FIGS. 6-8, one end of the surrounding plate 141 is outwardly folded with a connecting flange 1412, which is arranged around the surrounding plate 141, and the surrounding plate 141 is detachably connected to the first wall 111 through the connecting flange 1412 and the fastener 145 such as a screw, so that the soundproof cover 140 is mounted to the first wall 111. The connecting flange 1412 can be arranged in close contact with the outer wall surface of the first wall 111, which reduces the possibility of noise spreading outward from the connection between the surrounding plate 141 and the first wall 111, and the arrangement of the connecting flange 1412 also improves the convenience of assembling and disassembling the soundproof cover 140 and the first wall 111.

[0169] The heat exchange assembly of the embodiment is provided with the surrounding plate 141, which surrounds the ventilation structure 142. When noise propagates to the soundproof cover 140, the ventilation area of the soundproof cover 140 performs noise reduction through the ventilation structure 142, and noise propagating to other areas can be reflected, stopped, and absorbed by the surrounding plate 141, thereby improving the noise reduction effect of the soundproof cover 140.

[0170] According to some embodiments of the present application, the air guide 143 is adjustably mounted to the surrounding plate 141 along the first direction Z, and / or the air guide 143 is detachably mounted to the surrounding plate 141.

[0171] Optionally, the air guide 143 is adjustably mounted to the surrounding plate 141 along the first direction Z. For example, the air guide 143 can be slidably connected to the surrounding plate 141 along the first direction Z, and the surrounding plate 141 is provided with a slide rail, and the air guide 143 is slidably arranged on the slide rail. After the air guide 143 is slid into position, it can be fixedly connected to the slide rail by buckling, fasteners 145, or the like. Among them, the air guide 143 can be arranged to be unable to be separated from the slide rail, or can be arranged to be able to be separated from the slide rail and detachably cooperate with the slide rail. The air guide 143 can also be directly detached from the surrounding plate 141 and adjusted to the appropriate position. The position of the air guide 143 along the first direction Z can be adjusted, so that the gap between adjacent air guides 143 can be adjusted to adapt to different working conditions and environments.

[0172] Optionally, the air guide 143 is adjustably mounted to the surrounding plate 141 along the first direction Z, and / or the air guide 143 is detachably mounted to the surrounding plate 141.

[0173] According to some embodiments of the present application, the ventilation structure 142 further comprises fasteners 145, as shown in FIG. 14, which is a schematic view of a partial cross-section of the soundproof cover 140 according to some embodiments of the present application. The enclosing plate 141 is provided with guide positioning portions 146 extending along the first direction Z. The plurality of air guides 143 are respectively locked and fixed with the guide positioning portions 146 by the fasteners 145. When the fasteners 145 are loosened, the air guides 143 can move along the first direction Z relative to the guide positioning portions 146. The guide positioning portions 146 are provided in an integrated structure with the enclosing plate 141, or the guide positioning portions 146 are detachably mounted on the enclosing plate 141.

[0174] Optionally, the guide positioning portions 146 can be sliding rails, sliding grooves, or strip-shaped holes integrally provided on the enclosing plate 141, as shown in FIG. 14.

[0175] Optionally, the guide positioning portions 146 can be sliding rails, protruding blocks, or strip-shaped blocks provided separately from the enclosing plate 141. The guide positioning portions 146 can be detachably mounted on the enclosing plate 141 by clamping or screwing.

[0176] The fasteners 145 can be rivets or screws. The fasteners 145 pass through the air guides 143 and the guide positioning portions 146 to fix the air guides 143 on the guide positioning portions 146.

[0177] The air guides 143 are fixed on the guide positioning portions 146 by the fasteners 145 and the guide positioning portions 146, which is convenient to operate and simple in structure. When the guide positioning portions 146 are designed to be detachable, the plurality of air guides 143 can be adjusted in distance as needed, assembled to the guide positioning portions 146 offline, and then assembled to the enclosing plate 141 as a whole. The distance adjustment does not need to be performed on the whole machine, which is convenient and labor-saving. Furthermore, the guide positioning portions 146 and the air guides 143 are assembled as a whole, which facilitates the overall replacement of the ventilation structure 142.

[0178] According to some embodiments of the present application, the enclosing plate 141 is provided with guide positioning portions 146 at both ends along the third direction X. The air guides 143 are respectively connected with the guide positioning portions 146 at the corresponding ends along the third direction X. The third direction X, the second direction Y, and the first direction Z intersect with each other.

[0179] The air guides 143 can be provided with a plurality of guide positioning portions 146 at both ends along the third direction X. The plurality of guide positioning portions 146 at the same end can be spaced apart along the second direction Y. The air guides 143 and the guide positioning portions 146 are fixedly connected by the fasteners 145.

[0180] The two ends of the enclosing plate 141 of the heat exchange assembly in this embodiment are provided with guide positioning portions 146 along the third direction X, so that each air guide piece 143 can be better fixed by the guide positioning portions 146 at the two ends, and the plurality of air guide pieces 143 of the ventilation structure 142 are defined as a whole by the guide positioning portions 146, and can be assembled offline and then installed to the enclosing plate 141.

[0181] According to some embodiments of the present application, optionally, along the second direction Y, the ventilation structure 142 and the airflow guiding mechanism 130 have a spacing gap.

[0182] The spacing gap between the ventilation structure 142 and the airflow guiding mechanism 130 can reserve a distance between the ventilation opening of the airflow guiding mechanism 130 and the ventilation structure 142, form a ventilation transition section, reduce the wind resistance, and improve the guiding effect of the airflow guiding mechanism 130 on the airflow.

[0183] According to some embodiments of the present application, optionally, as shown in FIGS. 4-6, the second ventilation opening 112 is arranged on the shell 110, one of the first ventilation opening 113 and the second ventilation opening 112 is the air inlet of the shell 110, and the other is the air outlet of the shell 110, and the second ventilation opening 112 is arranged as a mesh structure 114.

[0184] The mesh structure 114 can be arranged at the second ventilation opening 112, the mesh holes of the mesh structure 114 can make the airflow formed by the air flow into the containing cavity, and the mesh structure 114 can also reduce the possibility of large sundries entering the shell 110 and the possibility of the operator stretching his hand into the containing cavity to cause danger. The mesh holes of the mesh structure 114 can be hexagonal mesh holes, diamond-shaped mesh holes, circular mesh holes, etc.

[0185] According to some embodiments of the present application, as shown in FIG. 4 and FIG. 5, and in combination with FIG. 15 to FIG. 21, FIG. 15 is a structural schematic diagram of one perspective view of the airflow guiding mechanism 130 according to some embodiments of the present application, FIG. 16 is a structural schematic diagram of another perspective view of the airflow guiding mechanism 130 according to some embodiments of the present application, FIG. 17 is a sectional view schematic diagram of the airflow guiding mechanism 130 according to some embodiments of the present application, FIG. 18 is an assembly sectional view of the air guide ring 132 and the impeller assembly 131 according to some embodiments of the present application, FIG. 19 is a structural schematic diagram of one perspective view of the impeller assembly 131 according to some embodiments of the present application, FIG. 20 is a structural schematic diagram of another perspective view of the impeller assembly 131 according to some embodiments of the present application, and FIG. 21 is a sectional view schematic diagram of the impeller assembly 131 according to some embodiments of the present application. The airflow guiding mechanism 130 includes the air guide ring 132 and the impeller assembly 131. The air guide ring 132 is installed on the first wall 111. The impeller assembly 131 includes the impeller 1312 and the blade 1313. The impeller 1312 is cylindrically arranged. The impeller 1312 surrounds the outside of the blade 1313 and is fixedly connected with the blade 1313. The two ends of the air guide ring 132 in the axial direction are the air ring air inlet end 1325 and the air ring air outlet end 1326, respectively. The two ends of the impeller 1312 in the axial direction are the impeller air inlet end 1316 and the impeller air outlet end 1317, respectively. In the axial direction of the impeller 1312, the air ring air outlet end 1326 is arranged inside the impeller air inlet end 1316. In the radial direction of the impeller 1312, the air guide ring 132 and the impeller 1312 are gap-fitted. The impeller assembly 131 is configured to be able to rotate relative to the air guide ring 132. The impeller 1312 is provided with a blocking part 136. The blocking part 136 is arranged to protrude from the outer peripheral wall of the impeller 1312.

[0186] When the first air vent 113 is used as the air inlet of the shell 110, the airflow guiding mechanism 130 according to the present embodiment can be installed on the inner wall surface of the first wall 111. When the first air vent 113 is used as the air outlet of the shell 110, the airflow guiding mechanism 130 according to the present embodiment can be installed on the outer wall surface of the first wall 111. The air guide air inlet end of the air guide ring 132 is used to connect with the first wall 111.

[0187] The air guide ring 132 can guide the air flow, and the air guide ring 132 can be connected with the first wall 111 to fix the air flow guiding mechanism 130 to the external fixing member. The air guide ring 132 is a substantially cylindrical structure, and a channel for the air flow is formed in the air guide ring 132. Specifically, the air guide ring 132 can be a cylindrical structure with a substantially circular or elliptical cross section, or a cylindrical structure with a polygonal or irregular cross section. The two axial ends of the air guide ring 132 are throughly arranged, and the two axial ends of the air guide ring 132 are the air ring air inlet end 1325 and the air ring air outlet end 1326, respectively. The air flow can flow from the air ring air inlet end 1325 to the air ring air outlet end 1326 along the inside of the air guide ring 132.

[0188] The impeller assembly 131 guides the air flow by rotating, and the flow direction of the air flow can be understood with reference to the arrow C. The impeller 1312 is cylindrically arranged, that is, the impeller 1312 is at least partially a substantially cylindrical structure. For example, the impeller 1312 can be a substantially circular cylindrical structure. Of course, the impeller 1312 can also be processed into other shapes of cylindrical structure according to needs. The side wall of the impeller 1312 can be closed to reduce the possibility of air flow leaking from the side wall of the impeller 1312 and easily flowing back to the impeller air inlet end 1316. The two axial ends of the impeller 1312 are throughly arranged, and a flow channel for the air flow is formed in the impeller 1312. The two axial ends of the impeller 1312 are the impeller air inlet end 1316 and the impeller air outlet end 1317, respectively. The air flow can flow from the air inlet end of the impeller 1312 to the air outlet end 1317 along the inside of the impeller 1312. The blades 1313 can be sheet or plate structures, and the blades 1313 can be arranged in one or more pieces. The blades 1313 can be arranged in the air guide ring 132 and fixedly connected with the inner circumferential wall of the air guide ring 132.

[0189] It can be understood that the flow direction of the air flow in the air guide ring 132 and the impeller assembly 131 can be substantially understood with reference to the axial direction of the air guide ring 132 and the axial direction of the impeller 1312. Optionally, the axial direction of the air guide ring 132 and the axial direction of the impeller 1312 can be substantially coaxially arranged. The radial direction of the air guide ring 132 is substantially perpendicular to the axial direction of the air guide ring 132, that is, substantially perpendicular to the direction of the air flow in the air guide ring 132. The radial direction of the impeller 1312 is substantially perpendicular to the axial direction of the impeller 1312, that is, substantially perpendicular to the direction of the air flow in the impeller 1312.

[0190] As shown in FIG. 17 and FIG. 18, the air ring outflow end 1326 is arranged inside the impeller inflow end 1316, so that the air ring outflow end 1326 communicates with the impeller inflow end 1316. The air ring outflow end 1326 is arranged inside the impeller inflow end 1316, that is, the impeller inflow end 1316 is sleeved outside the air ring 132, and the connection between the air ring outflow end 1326 and the impeller inflow end 1316 forms a stepped surface. The stepped surface in the airflow flow path (i.e., the end surface of the air ring outflow end 1326) is oriented in the same direction as the airflow flow direction, so that the airflow flowing from the air ring outflow end 1326 to the impeller 1312 is not easily interfered by the stop.

[0191] In the radial direction of the air ring 132, the air ring 132 is gap-fitted with the impeller 1312, mainly to enable the impeller 1312 to rotate around its own axis. The gap-fitting between the air ring 132 and the impeller 1312 is mainly gap-fitting between the air ring outflow end 1326 and the impeller inflow end 1316 in the radial direction of the air ring outflow end 1326 (also in the radial direction of the impeller inflow end 1316), that is, the impeller 1312 and the sleeved part of the air ring 132 are gap-fitted, so that the impeller 1312 can rotate around its own axis.

[0192] The outer peripheral wall of the impeller 1312 refers to the wall surface of the peripheral wall of the impeller 1312 facing the outside, which constitutes two opposite sides of the peripheral wall of the impeller 1312 with the inner peripheral wall of the impeller 1312. The blocking part 136 is arranged to protrude from the outer peripheral wall of the impeller 1312. It can be understood that at least part of the blocking part 136 is arranged more outward relative to the outer peripheral wall (the outer peripheral wall of the impeller 1312) in the radial direction of the impeller 1312. The blocking part 136 can be arranged in one or multiple in the axial direction of the impeller 1312. In the circumferential direction of the impeller 1312, each blocking part 136 can be arranged in a full circle or only a part of a circle, such as half a circle, 1 / 4 of a circle, etc. The blocking part 136 can be integrally formed with the impeller 1312, or can be connected as an integral structure by welding or other methods. Of course, the blocking part 136 can also be fixedly connected to the impeller 1312 in other ways.

[0193] Optionally, in some embodiments, a plurality of blocking parts 136 are arranged in the axial direction of the impeller 1312. In adjacent two blocking parts 136, the protruding height of the blocking part 136 close to the impeller inflow end 1316 is less than the protruding height of the blocking part 136 close to the impeller inflow end 1316. In this embodiment, the closer to the impeller inflow end 1316, the higher the protruding height of the blocking part 136, which can further stop the airflow flowing backward from the impeller outflow end 1317.

[0194] Optionally, the airflow guiding mechanism 130 further comprises a driving member 134 for driving the rotation of the impeller assembly 131, the driving member 134 can be connected with the impeller assembly 131 through an axle 1311, and the blades 1313 are connected on the axle 1311, and the driving member 134 drives the rotation of the axle 1311, the blades 1313 and the impeller 1312. The driving member 134 can be a motor or the like.

[0195] Optionally, the airflow guiding mechanism 130 can further comprise a fixing assembly 133 for connecting the impeller assembly 131 and the air guide ring 132, the fixing assembly 133 can fix the impeller assembly 131 to the air guide ring 132 while keeping the freedom of the impeller assembly 131 rotating around its own axis, so that the assembly of the airflow guiding mechanism 130 can be completed by connecting the air guide ring 132 with the external fixing member.

[0196] When the airflow guiding mechanism 130 operates, the impeller assembly 131 rotates to press the airflow from the air guide ring 132 to the air outlet of the impeller assembly 131 (i.e. the air outlet end 1317 of the impeller). The air guide ring 132 is inserted into the impeller inlet end 1316 of the impeller 1312, so that the stepped surface formed by the sleeve connection of the air guide ring 132 and the impeller 1312 can avoid the flow path of the airflow, improve the smoothness of the airflow, and reduce the possibility of turbulence and noise caused by the airflow from the air guide ring 132 to the impeller 1312. At the same time, the blocking part 136 can block the airflow flowing in the opposite direction of the impeller 1312, reduce the possibility of the airflow flowing out of the air outlet of the impeller 1312 re-entering the impeller 1312 through the gap between the air guide ring 132 and the impeller 1312, and causing the airflow in the impeller 1312 to separate and turbulent, further reducing the noise of the airflow, and reducing the overall operating noise of the airflow guiding mechanism 130 and the heat exchange equipment 101 applying the airflow guiding mechanism 130.

[0197] According to some embodiments of the present application, the impeller inlet end 1316 is provided with a blocking part 136.

[0198] The impeller inlet end 1316 includes the circumferential wall of the impeller 1312 close to the end face of the inlet end and the end face of the inlet end. That is, the blocking part 136 can be provided on the circumferential wall or the end face of the impeller 1312 close to the air guide ring 132. Optionally, the circumferential wall corresponding to the connection position of the impeller 1312 and the air guide ring 132 can be provided with the blocking part 136, and specifically, the blocking part 136 can be a structure formed by outwardly folding the end face of the impeller inlet end 1316.

[0199] The air flow guiding mechanism 130 of the embodiment blocks the air flow backflowing to the impeller air inlet end 1316 by arranging a blocking part 136 at the impeller air inlet end 1316. The blocking part 136 can directly block and interfere with the air flow backflowing to the impeller air inlet end 1316, reduce the air flow backflowing from the impeller air outlet end 1317 to the impeller assembly 131 through the impeller air inlet end 1316, and reduce the operation noise of the air flow guiding mechanism 130.

[0200] According to some embodiments of the present application, the blocking part 136 and the impeller 1312 are an integral structure, as shown in FIGS. 17 and 18.

[0201] The blocking part 136 can be integrally formed with the impeller 1312 in a pouring / injection or other manner. The blocking part 136 can also be integrally connected in a welding or other manner. Alternatively, the blocking part 136 can be a structure formed by the outer peripheral wall of the impeller 1312 protruding outward, or a structure formed by the end of the impeller 1312 being folded outward.

[0202] The blocking part 136 and the impeller 1312 are arranged as an integral structure in the embodiment, and the blocking part 136 and the outer peripheral wall of the impeller 1312 can be seamlessly connected, improving the blocking effect of the blocking part 136 on the air flow.

[0203] According to some embodiments of the present application, the blocking part 136 is arranged in a closed loop around the outer peripheral wall (the outer peripheral wall of the impeller 1312) in the circumferential direction of the impeller 1312, as shown in FIGS. 17 to 21.

[0204] That is, the blocking part 136 is arranged in a circle on the outer peripheral part in the circumferential direction of the impeller 1312. It should be noted that when multiple blocking parts 136 are arranged in the axial direction of the impeller 1312, one of the blocking parts 136 can be arranged in a circle, and the other blocking parts 136 can be arranged in a circle or arranged locally in the circumferential direction.

[0205] Alternatively, the blocking part 136 can be integrally connected with the outer peripheral wall of the impeller 1312 at any position in the circumferential direction of the impeller 1312, so that the blocking part 136 and the outer peripheral wall of the impeller 1312 are seamlessly connected, reducing the possibility of air flow backflowing to the impeller air inlet end 1316 along the surface of the outer peripheral wall of the impeller 1312.

[0206] The air flow guiding mechanism 130 of the embodiment can block the air flow at any position in the circumferential direction of the impeller 1312, reducing the possibility of the air flow backflowing from the impeller air outlet end 1317 to the impeller assembly 131 through the impeller air inlet end 1316, and reducing the operation noise of the air flow guiding mechanism 130.

[0207] According to some embodiments of the present application, as shown in FIGS. 17-21, the blocking portion 136 includes a first stop segment 1361, one end of the first stop segment 1361 is connected with the outer peripheral wall (the outer peripheral wall of the impeller 1312), and the first stop segment 1361 is arranged to protrude radially from the outer peripheral wall (the outer peripheral wall of the impeller 1312) of the impeller 1312, or the first stop segment 1361 is arranged to gradually approach the air outlet end 1317 of the impeller from one end connected with the outer peripheral wall (the outer peripheral wall of the impeller 1312) to the other end away from the outer peripheral wall (the outer peripheral wall of the impeller 1312).

[0208] Optionally, in one implementation, as shown in FIGS. 17-21, the first stop segment 1361 is arranged to protrude radially from the outer peripheral wall (the outer peripheral wall of the impeller 1312) of the impeller 1312. That is, the protruding direction of the first stop segment 1361 is substantially the same as the radial direction of the impeller 1312, the protruding direction of the first stop segment 1361 is substantially perpendicular to the axial direction of the impeller 1312, and the first stop segment 1361 is perpendicular to the outer peripheral wall (the outer peripheral wall of the impeller 1312) of the impeller 1312.

[0209] Optionally, in another implementation, the end of the first stop segment 1361 away from the outer peripheral wall (the outer peripheral wall of the impeller 1312) is arranged closer to the air outlet end 1317 of the impeller than the end of the first stop segment 1361 connected with the outer peripheral wall (the outer peripheral wall of the impeller 1312). Optionally, the first stop segment 1361 can gradually change, that is, the first stop segment 1361 can be arranged to gradually approach the air outlet end 1317 of the impeller from one end connected with the outer peripheral wall (the outer peripheral wall of the impeller 1312) to the other end away from the outer peripheral wall (the outer peripheral wall of the impeller 1312). Specifically, as shown in FIG. 22, which is a partial cross-sectional schematic view of an impeller assembly according to some embodiments of the present application, in some specific implementations, the first stop segment 1361 can be arranged to be inclined toward the side where the air outlet end 1317 of the impeller is located from one end connected with the outer peripheral wall (the outer peripheral wall of the impeller 1312) to the other end away from the outer peripheral wall (the outer peripheral wall of the impeller 1312), that is, the protruding direction of the first stop segment 1361 is inclined relative to the radial direction of the impeller 1312, and the first stop segment 1361 is inclined toward the air inlet end 1316 of the impeller. In another implementation, the first stop segment 1361 can be arranged to be arc-shaped curved toward the side where the air outlet end 1317 of the impeller is located from one end connected with the outer peripheral wall (the outer peripheral wall of the impeller 1312) to the other end away from the outer peripheral wall (the outer peripheral wall of the impeller 1312).

[0210] The first stop segment 1361 of the airflow guiding mechanism 130 is arranged substantially perpendicular to the outer circumferential wall (the outer circumferential wall of the impeller 1312) or gradually approaches the air outlet end 1317 of the impeller, the protruding direction A of the first stop segment 1361 and the flow direction B of the airflow from the air outlet end 1317 of the impeller are at an angle a less than or equal to 90 degrees, which can better stop the reverse airflow, further reduce the possibility of the airflow from the air outlet end 1317 of the impeller flowing back to the impeller assembly 131 through the air inlet end 1316, and reduce the operation noise of the airflow guiding mechanism 130.

[0211] According to some embodiments of the present application, the blocking part 136 includes a first stop segment 1361, which is arranged to be folded radially outward from the outer circumferential wall of the impeller 1312.

[0212] As shown in FIGS. 17-21, the first stop segment 1361 can be folded radially outward from the outer circumferential wall of the air inlet end 1316. Alternatively, the first stop segment 1361 can also be folded radially outward from the outer circumferential wall of the air outlet end 1317.

[0213] The first stop segment 1361 is folded from the outer circumferential wall of the impeller 1312, which is simple in structure and has an integrated structure between the outer circumferential wall of the impeller 1312 and the first stop segment 1361, thereby reducing the possibility of reverse airflow from the connection between the outer circumferential wall of the impeller 1312 and the first stop segment 1361, further reducing the possibility of the airflow from the air outlet end 1317 of the impeller flowing back to the impeller assembly 131 through the air inlet end 1316, and reducing the operation noise of the airflow guiding mechanism 130.

[0214] According to some embodiments of the present application, as shown in FIG. 23, the blocking part 136 further includes a second stop segment 1362, one end of the first stop segment 1361 away from the outer circumferential wall (the outer circumferential wall of the impeller 1312) is connected to one end of the second stop segment 1362, and the second stop segment 1362 is located on the side of the first stop segment 1361 close to the air outlet end 1317 of the impeller along the axial direction of the impeller 1312, the second stop segment 1362 is arranged at an acute angle, a right angle or an obtuse angle with the first stop segment 1361, and the second stop segment 1362 is arranged spaced apart from the outer circumferential wall (the outer circumferential wall of the impeller 1312).

[0215] The first stop section 1361 can be a straight section or a curved or bent meandering section along the radial direction of the impeller 1312. The second stop section 1362 can be a straight section or a curved or bent meandering section along the radial direction of the impeller 1312. The first stop section 1361 can be connected with the second stop section 1362 at any position along the circumferential direction of the impeller 1312, or the first stop section 1361 can be connected with the second stop section 1362 at a partial position along the circumferential direction of the impeller 1312. The first stop section 1361 and the second stop section 1362 can be an integral structure. The first stop section 1361 and the second stop section 1362 can be directly connected in a straight or bent manner, or can be connected in an arc-shaped section or other transition bent manner.

[0216] The first stop section 1361 is away from the outer circumferential wall (the outer circumferential wall of the impeller 1312) along the radial direction of the impeller 1312, that is, the outer end of the first stop section 1361 along the radial direction of the impeller 1312.

[0217] The side of the first stop section 1361 close to the impeller air outlet end 1317 refers to the side of the first stop section 1361 facing the impeller air outlet end 1317. The second stop section 1362 is spaced apart from the outer circumferential wall (the outer circumferential wall of the impeller 1312), that is, a gap for airflow to enter is provided between the second stop section 1362 and the outer circumferential wall (the outer circumferential wall of the impeller 1312). Specifically, as shown in FIG. 23, the second stop section 1362 can be spaced apart from the outer circumferential wall (the outer circumferential wall of the impeller 1312) at any position from the end away from the first stop section 1361 to the end connected with the first stop section 1361, so that the reverse flow of airflow from the impeller air outlet end 1317 can enter between the second stop section 1362 and the outer circumferential wall (the outer circumferential wall of the impeller 1312).

[0218] In some implementations, the second stop section 1362 is arranged at an acute angle with the first stop section 1361, that is, along the axial direction of the impeller 1312, the end of the second stop section 1362 connected with the first stop section 1361 is closer to the outer circumferential wall (the outer circumferential wall of the impeller 1312) than the end of the second stop section 1362 away from the first stop section 1361 (which is the end of the second stop section 1362 close to the impeller air outlet end 1317).

[0219] In some implementations, the second stop section 1362 is arranged at an obtuse angle with the first stop section 1361, that is, along the axial direction of the impeller 1312, the end of the second stop section 1362 connected with the first stop section 1361 is farther away from the outer circumferential wall (the outer circumferential wall of the impeller 1312) than the end of the second stop section 1362 away from the first stop section 1361 (which is the end of the second stop section 1362 close to the impeller air outlet end 1317).

[0220] In some implementations, as shown in FIG. 23, the second stop segment 1362 is bent at a right angle with the first stop segment 1361, that is, the second stop segment 1362 is arranged perpendicularly with the first stop segment 1361.

[0221] In the air flow guide mechanism 130 of the embodiment, the second stop segment 1362 is arranged on the side of the first stop segment 1361 close to the impeller air outlet end 1317, and the second stop segment 1362 is arranged spaced apart from the outer peripheral wall (the outer peripheral wall of the impeller 1312). The second stop segment 1362 can cooperate with the first stop segment 1361 to form a stop groove with an opening facing the impeller air outlet end 1317. Under the restriction of the second stop segment 1362, the stop effect on the air flow flowing reversely from the impeller air outlet end 1317 can be further improved, the possibility of the air flow discharged from the impeller air outlet end 1317 flowing reversely to the impeller assembly 131 through the impeller air inlet end 1316 can be further reduced, and the operation noise of the air flow guide mechanism 130 can be reduced.

[0222] According to some embodiments of the present application, as shown in FIG. 23, the blocking part 136 further includes a second stop segment 1362, which is formed by folding the outer end of the first stop segment 1361 in the radial direction of the impeller 1312 in the axial direction of the impeller 1312.

[0223] The second stop segment 1362 is formed by folding the first stop segment 1361, which is simple in structure and convenient to process. Moreover, the connection between the second stop segment 1362 and the first stop segment 1361 is an integral structure, which reduces the possibility of the air flow flowing reversely from the connection between the second stop segment 1362 and the first stop segment 1361, further reduces the possibility of the air flow discharged from the impeller air outlet end 1317 flowing reversely to the impeller assembly 131 through the impeller air inlet end 1316, and reduces the operation noise of the air flow guide mechanism 130.

[0224] According to some embodiments of the present application, as shown in FIGS. 17 and 18, the flow passage cross section of the air guide ring 132 is arranged in a tapered shape along the direction from the air ring air inlet end 1325 to the air ring air outlet end 1326.

[0225] The direction from the air ring air inlet end 1325 to the air ring air outlet end 1326 is also the flow direction of the air flow. Along the flow direction of the air flow, the air guide ring 132 can be at least partially arranged in a tapered shape, so that the flow area of the air flow gradually decreases, to improve the air guide effect on the air flow.

[0226] Optionally, in some implementations, the air guide ring 132 includes a first air guide section 1323 and a second air guide section 1324, and the flow passage cross section of the first air guide section 1323 is arranged to be tapered in the direction from the air guide ring air inlet end 1325 to the air guide ring air outlet end 1326, the air outlet end of the first air guide section 1323 is arranged to be connected and communicated with the air inlet end of the second air guide section 1324, and the second air guide section 1324 is a straight cylinder section and is inserted into the impeller air inlet end 1316.

[0227] The flow passage cross section can be understood as the cross section of the region through which the airflow passes in the airflow channel. Specifically, the flow passage cross section of the first air guide section 1323 is the cross section of the airflow channel formed by the first air guide section 1323 along the axial direction of the first air guide section 1323; and the flow passage cross section of the second air guide section 1324 is the cross section of the airflow channel formed by the second air guide section 1324 along the axial direction of the second air guide section 1324.

[0228] The direction from the air guide ring air inlet end 1325 to the air guide ring air outlet end 1326 is the flow direction of the airflow in the air guide ring 132. The flow passage cross section of the first air guide section 1323 is tapered in the flow direction of the airflow, which can better guide the airflow. The first air guide section 1323 can be a section with the same flow passage cross section change rate, or can include multiple sub-sections with different flow passage cross section change rates. Optionally, in some embodiments, the first air guide section 1323 includes a first sub-section 1327 and a second sub-section 1328, and the first sub-section 1327, the second sub-section 1328, and the second air guide section 1324 are sequentially connected and communicated in the flow direction of the airflow, the flow passage cross section change rate of the first sub-section 1327 is greater than that of the second sub-section 1328, that is, the first sub-section 1327 is more obviously tapered than the second sub-section 1328, for example, the first sub-section 1327 and the second sub-section 1328 are both arranged to be arc-shaped and tapered in the axial direction, and the curvature of the first sub-section 1327 is greater than that of the second sub-section 1328. By arranging the flow passage cross section change rate of the first sub-section 1327 to be greater than that of the second sub-section 1328, the airflow guiding effect can be improved, and the noise can be reduced.

[0229] The air outlet end of the second air guide section 1324 is arranged to be connected and communicated with the air inlet end of the second air guide section 1324, which means that the flow passage cross section of the second air guide section 1324 is substantially the same as the flow passage cross section of the air outlet end of the first air guide section 1323 in terms of area and shape, so that the air outlet end of the first air guide section 1323 is connected with the air inlet end of the second air guide section 1324, and the airflow can flow smoothly at this position.

[0230] The second air guide section 1324 is a straight cylinder section. It can be understood that the shape and area of the flow section of the second air guide section 1324 remain unchanged from the air inlet end to the air outlet end. The second air guide section 1324 is arranged as a straight cylinder section and is used to be inserted into the air inlet end 1316 of the impeller. This can improve the matching degree between the second air guide section 1324 and the impeller 1312, reduce the gap between the air guide ring 132 and the impeller 1312 in the radial direction, reduce the flow of air (air flowing out of the air outlet of the impeller 1312) flowing back through the gap between the air guide ring 132 and the impeller 1312 and then entering the impeller 1312 again, and reduce noise. It should be noted that the air inlet end 1316 of the impeller 1312 can be arranged as a straight cylinder section to better match the second air guide section 1324.

[0231] The structure of the air guide ring 132 of the air flow guide mechanism 130 can not only play a good guiding effect, but also reduce the flow of air (air flowing out of the air outlet of the impeller 1312) flowing back through the gap between the air guide ring 132 and the impeller 1312 and then entering the impeller 1312 again, and reduce noise.

[0232] According to some embodiments of the present application, as shown in FIGS. 17-23, along the axial direction of the impeller 1312, the two ends of the blade 1313 do not exceed the end surface of the corresponding end of the impeller 1312.

[0233] The two ends of the blade 1313 do not exceed the end surface of the corresponding end of the impeller 1312. It can be understood that the blade 1313 is entirely located within the axial dimension of the impeller 1312. The end surface of the blade 1313 facing the air outlet end 1317 of the impeller can be flush with or located inside the air outlet end 1317 of the impeller. The end surface of the blade 1313 facing the air inlet end 1316 of the impeller can be flush with or located inside the air inlet end 1316 of the impeller. The blade 1313 is entirely located within the axial dimension of the impeller 1312, which can improve the cooperation between the blade and the impeller 1312 and improve the guiding ability of the air flow guide mechanism 130.

[0234] According to some embodiments of the present application, as shown in FIGS. 17-23, along the axial direction of the impeller 1312, the distance between the blade 1313 and the end surface of the air outlet end 1317 of the impeller is a first size, and the distance between the blade 1313 and the end surface of the air inlet end 1316 of the impeller is a second size L. The first size is smaller than the second size L.

[0235] Optionally, along the axial direction of the impeller 1312, the two ends of the blade 1313 do not exceed the end surface of the corresponding end of the impeller 1312, respectively, and the first size is smaller than the second size L. The first size is the interval distance between the end surface of the blade 1313 towards the outflow end 1317 of the impeller and the end surface of the outflow end 1317 of the impeller along the axial direction of the impeller 1312. The second size L is the interval distance between the end surface of the blade 1313 towards the inflow end 1316 of the impeller and the end surface of the inflow end 1316 of the impeller along the axial direction of the impeller 1312. It should be noted that the first size can be zero (i.e. the blade 1313 is flush with the end surface of the outflow end 1317 of the impeller) or positive. Since the first size is smaller than the second size L, the second size L is positive, so the end surface of the impeller 1312 towards the inflow end 1316 of the impeller is located inside the inflow end 1316 of the impeller. It can be understood that the second size L is larger, which can provide assembly space for the air guide ring 132, so that the air guide ring 132 can be inserted into the inflow end of the impeller 1312 without interfering with the blade 1313 in the axial direction, and the first size is smaller, which can make the outflow end 1317 of the impeller have a higher airflow pressure, which is conducive to promoting the rapid flow of airflow.

[0236] According to some embodiments of the present application, optionally, referring to FIGS. 15-17, and in combination with FIG. 24, which is a schematic diagram of part of the airflow guiding mechanism according to some embodiments of the present application, the air guide ring 132 further comprises an assembly portion 1322, the outer wall surface of the inflow end 1325 of the air guide ring is connected with the assembly portion 1322, the assembly portion 1322 extends outwardly along the radial direction of the impeller 1312, and the assembly portion 1322 is used to be connected with an external fixing member.

[0237] For the convenience of description and understanding, the main part of the air guide ring 132 is defined as the cover portion 1321. Specifically, the air guide ring 132 comprises the cover portion 1321 and the assembly portion 1322, the two ends of the cover portion 1321 along the axial direction of the air guide ring 132 are the inflow end 1325 and the outflow end 1326 of the air guide ring, respectively, the outer wall surface of the inflow end 1325 of the cover portion 1321 is connected with the assembly portion 1322, the assembly portion 1322 is used to be connected with an external fixing member, and the airflow guiding mechanism 130 further comprises a fixing assembly 133, the impeller assembly 131 is installed on the assembly portion 1322 through the fixing assembly 133.

[0238] The assembly portion 1322 is fixedly connected with the cover portion 1321, and the two can be an integrated structure. Optionally, the assembly portion 1322 can be a structure formed by outwardly folding the inflow end 1325 of the cover portion 1321. Optionally, the assembly portion 1322 can be a flange structure, and the assembly portion 1322 can be detachably connected with an external fixing member through a bolt or the like.

[0239] The air flow guiding mechanism 130 can fix the air guide ring 132 to the external fixing member by setting the assembling part 1322.

The fixing assembly 133 connects the impeller assembly 131 and the assembling part 1322, so that the impeller assembly 131 is installed on the assembling part. It should be noted that the fixing assembly 133 is relatively fixed with the assembling part 1322, and the impeller assembly 131 can rotate relative to the fixing assembly 133. For example, the fixing assembly 133 can comprise a connecting frame 1330 and a bearing fixed on the connecting frame 1330, the connecting frame 1330 is fixedly connected with the assembling part 1322, and the bearing is connected with the wheel shaft 1311 of the impeller assembly 131 through a shaft, so that the impeller assembly 131 can rotate relative to the fixing assembly 133, and can be installed on the assembling part 1322 through the fixing assembly 133; for another example, the fixing assembly 133 can be connected with a fixed part of a driving part 134 (such as a motor) of the impeller assembly 131, and a driving output end 1343 of the driving part 134 is connected with the impeller assembly 131, so that the impeller assembly 131 can rotate relative to the fixing assembly 133, and can be installed on the assembling part 1322 through the fixing assembly 133.

[0241] The air flow guiding mechanism 130 of the embodiment sets the air guide ring 132 on the assembling part 1322, and installs the impeller assembly 131 on the assembling part 1322, so that the air guide ring 132 and the impeller assembly 131 are integrated, and the structure is simple. By connecting the assembling part 1322 with the external fixing member, the whole air flow guiding mechanism 130 can be fixed on the external fixing member, and the operation is convenient.

[0242] According to some embodiments of the present application, as shown in FIG. 15 to FIG. 17, and in combination with FIG. 24, the air flow guiding mechanism 130 further comprises a driving part 134, and the impeller assembly 131 further comprises a wheel shaft 1311, the wheel shaft 1311 is arranged in the impeller 1312, the blades 1313 are connected with the wheel shaft 1311, and the driving part 134 is connected with one end of the wheel shaft 1311 away from the air guide ring 132 along the axial direction of the impeller 1312.

[0243] The blades 1313 and the wheel shaft 1311 can be arranged at intervals along the axial direction of the impeller 1312, so that the impeller assembly 131 can rotate around its own axis, and the possibility of mutual interference between the impeller assembly 131 and the air guide ring 132 is reduced.

[0244] Optionally, the plurality of blades 1313 are connected to the wheel shaft 1311 at intervals along the circumference of the wheel shaft 1311. The blade 1313, the wheel shaft 1311 and the impeller 1312 can be an integrated structure.

[0245] The driving member 134 can include a motor, and an output shaft of the motor is fixedly connected to the wheel shaft 1311 to drive the impeller assembly 131 to rotate about the axis thereof.

[0246] In some embodiments, the impeller assembly 131 can be supported and fixed by the output shaft of the motor, and the driving member 134 is fixedly connected to the assembly portion 1322 by the fixing assembly 133, so that the fixing assembly 133 can support and fix the driving member 134 and the impeller assembly 131. Specifically, the airflow guiding mechanism 130 further includes the driving member 134, and the impeller assembly 131 further includes the wheel shaft 1311 arranged in the impeller 1312, the blade 1313 connected to the wheel shaft 1311, and the blade 1313 and the wheel shaft 1311 are both arranged at intervals along the axis of the impeller 1312 from the air guide ring 132.

Through the detachable manner, the disassembly and maintenance of the driving member 134 and the impeller assembly 131 are facilitated.

[0248] The airflow guiding mechanism 130 of the present embodiment integrates the driving member 134, the impeller assembly 131 and the air guide ring 132 into one body, which facilitates the assembly of the airflow guiding mechanism 130 and the external fixing member, and the impeller assembly 131 and the driving member 134 are fixedly connected to the assembly portion 1322 by the same fixing assembly 133, which is simple in structure and convenient to disassemble and assemble.

[0249] According to some embodiments of the present application, the wheel shaft 1311 is provided with an installation cavity 1314, and the driving member 134 is arranged in the installation cavity 1314, and the driving member 134 is arranged to drive the wheel shaft 1311 to rotate the impeller assembly 131.

[0250] In an optional implementation, the wheel shaft 1311 is provided with a mounting cavity 1314 penetrating an end surface of the wheel shaft 1311 away from the guide ring 132, and the wheel shaft 1311 is further provided with a transmission portion 1315 located at an end of the wheel shaft 1311 close to the guide ring 132. The partial driving member 134 is arranged in the mounting cavity 1314 and is in clearance fit with a hole wall of the mounting cavity 1314. The driving output end 1343 of the driving member 134 is connected with the transmission portion 1315 to drive the wheel shaft 1311 to rotate to drive the impeller assembly 131.

[0251] As shown in FIGS. 17-23, the mounting cavity 1314 is hollow in the wheel shaft 1311. An end of the mounting cavity 1314 away from the guide ring 132 is in open structure, and an end of the mounting cavity 1314 close to the guide ring 132 is sealed. The body of the motor is inserted into the mounting cavity 1314 and is in clearance fit with the mounting cavity 1314, so that the impeller assembly 131 can rotate relative to the body of the motor. The output shaft of the motor is fixedly connected with the transmission portion 1315, so that the output shaft of the motor can drive the impeller assembly 131 to rotate.

[0252] The transmission portion 1315 and the driving output end 1343 can be connected by a key or fixedly connected by a bolt. Optionally, in a specific implementation, the transmission portion 1315 is provided with a polygonal hole, and the driving output end 1343 is provided in a polygonal structure. The driving output end 1343 is inserted into the polygonal hole to relatively fix the driving output end 1343 and the transmission portion 1315 in the circumferential direction. The driving output end 1343 is provided with a limiting portion 1345 on the inner side of the polygonal hole (the side of the polygonal hole facing the mounting cavity 1314). The driving output end 1343 penetrates the polygonal hole and is screwed with a nut assembly 1344 on the outer side of the polygonal hole (the side of the polygonal hole away from the mounting cavity 1314). The nut assembly 1344 and the limiting portion 1345 relatively fix the driving output end 1343 and the transmission portion 1315 in the axial direction to achieve the fixed connection of the driving output end 1343 and the wheel shaft 1311.

[0253] It should be noted that, in the axial direction of the impeller assembly 131, the body of the driving member 134 can be entirely located in the mounting cavity 1314 or partially protrude from the mounting cavity 1314.

[0254] The airflow guide mechanism 130 of the embodiment has the driving member 134 at least partially built in the mounting cavity 1314, so that the airflow guide mechanism 130 has a smaller volume and saves cost. The driving member 134 is substantially built in the mounting cavity 1314, which can reduce the damage of rainwater and the like to the driving member 134 and improve the reliability of the driving member 134.

[0255] According to some embodiments of the present application, the air flow guiding mechanism 130 further comprises a protective mesh cover 135, which covers the radial outer side of the impeller assembly 131 along the impeller 1312, as shown in FIGS. 15-17 and 24.

[0256] The protective mesh cover 135 is a meshed cover structure, which can be mounted on the assembly portion 1322 and covers the end of the impeller assembly 131 away from the air guide ring 132. The driving member 134 can be located wholly or partially within the protective mesh cover 135.

[0257] By providing the protective mesh cover 135, the air flow guiding mechanism 130 can meet the air outlet requirement, reduce the entry of foreign matters into the air flow guiding mechanism 130, improve the reliability of the air flow guiding mechanism 130, and reduce the risk of the operator being injured by the air flow guiding mechanism 130.

[0258] Optionally, in some implementations, the protective mesh cover 135 can be provided with an assembly hole 1351, the driving member 134 partially protrudes from the mounting cavity 1314 and is located in the assembly hole 1351, one end of the fixing assembly 133 is connected with the driving member 134, and the other end bypasses the protective mesh cover 135 and is connected with the assembly portion 1322, and the protective mesh cover 135 is pressed against the assembly portion 1322 by the fixing assembly 133.

The connecting frame 1330 can be spaced apart along the circumferential direction of the protective mesh cover 135. The first connecting portion 1331 can be provided with a connecting plate 1333, which is attached to the assembly portion 1322 and can be fixedly connected with the assembly portion 1322 by bolts or other fasteners.

The positioning ring plate 1334 is supported and fixed by the connecting frame 1330, and the positioning ring plate 1334 can limit the movement of the protective mesh cover 135 in the radial direction, thereby improving the assembly stability of the protective mesh cover 135. The positioning ring plate 1334 and the second connecting portion 1332 can be detachably connected by bolts or the like.

[0260] Optionally, the driving member 134 can have a small part exposed on the outside of the protective mesh cover 135, and this part can be connected with a power line assembly 1342 for supplying power to the driving member 134. By arranging the power line assembly 1342 outside, the power line assembly 1342 is less likely to interfere with the protective mesh cover 135, thereby improving the convenience of connecting the power line assembly 1342 with the power supply.

[0261] The embodiment has simple structure and high assembly stability, and when the impeller assembly 131 needs to be maintained, the protective mesh cover 135, the driving member 134 and the impeller assembly 131 can be disassembled by disassembling the fixing assembly 133, thereby improving the convenience of operation.
