Description

Technical Field

[0001] This application relates to the technical field of generator sets, and in particular to a containerized gas generator set. Background Technology

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It consists of a power system, control system, noise reduction system, vibration damping system, and exhaust system. Driven by a water turbine, steam turbine, diesel engine, or other power machinery, it converts energy from water flow, airflow, fuel combustion, or nuclear fission into mechanical energy, which is then transferred to the generator. The generator then converts this mechanical energy into electrical energy, which is output to electrical equipment. Among these, containerized gas generator sets are a highly efficient and reliable energy source. Their working principle involves using a gas engine to drive a generator to produce electrical energy. They are highly efficient, reliable, environmentally friendly, and safe energy devices with broad application prospects and market demand.

[0003] Existing containerized gas generator sets require continuous ventilation during operation to help dissipate heat and reduce the probability of overheating, damage, or even safety accidents. Furthermore, in hot weather, the interior of the container also needs to be cooled to meet the heat dissipation requirements for normal operation of the containerized gas generator set.

[0004] However, during the ventilation and cooling processes of containerized gas generator sets, the air inside the container needs to be exchanged with the outside air. During this process, dust and other impurities in the air can easily reach the generator body, thus affecting the normal operation of the generator body. Summary of the Invention

[0005] This application provides a containerized gas generator set that can meet its own heat dissipation requirements during normal operation and effectively reduce the impact of dust and other impurities on the generator body.

[0006] This application provides a containerized gas generator set, which adopts the following technical solution: A containerized gas generator set includes a container, multiple generators, a dust removal device, a ventilation device, and a refrigeration device; The housing has a working chamber, a first heat dissipation chamber, and a second heat dissipation chamber inside. Multiple generators are disposed within the working chamber. The first heat dissipation chamber is located below the working chamber, and the second heat dissipation chamber is located on one side of the working chamber and the first heat dissipation chamber. The housing has an air inlet on the side of the first heat dissipation chamber facing away from the second heat dissipation chamber, several heat dissipation vents between the working chamber and the first heat dissipation chamber, several ventilation vents between the first heat dissipation chamber and the second heat dissipation chamber, and an air outlet and a return outlet communicating with the top of the working chamber are located at the top of the second heat dissipation chamber. The dust removal device includes multiple filters for intercepting impurities, and the multiple filters are respectively disposed at the air inlet, the heat dissipation port, the air outlet and the return port; Both the ventilation device and the cooling device are disposed in the second heat dissipation cavity. The ventilation device is used to drive the air to move upward in the second heat dissipation cavity, and the cooling device is used to cool and lower the temperature of the air around it. It also includes a first control device for controlling the opening and closing of the air outlet and the return port, wherein the first control device keeps the air outlet and the return port in opposite open / closed states.

[0007] By adopting the above technical solution, cooled air can be used to drive air absorbing heat from the generator through the heat dissipation vents, meeting the heat dissipation requirements for the normal operation of the containerized gas generator set. Simultaneously, multiple filters effectively prevent dust and other impurities from entering the working chamber, thereby reducing the probability of dust and other impurities entering the working chamber and thus effectively minimizing their impact on the generator body. Furthermore, it allows operators to easily select appropriate cooling methods based on the operating environment temperature of the containerized gas generator set. When the operating environment temperature is lower than the generator's operating temperature, the air inside the container can be directly discharged through the air outlet to achieve cooling. When the operating environment temperature is higher than the generator's operating temperature, the cooled air inside the container is circulated internally as much as possible to improve the utilization rate of the cooled air and enhance the efficiency and effectiveness of cooling the generator.

[0008] Optionally, the first control device includes a rotating drum and a first drive component; The rotating cylinder has an internal cavity, and its outer side has two openings for the second heat dissipation cavity to communicate with the cavity and has a through-hole. The rotating cylinder is provided with the filter screen at the through-hole. The rotating cylinder is rotatably connected to the box body and is located at the top of the second heat dissipation cavity. Its rotation axis is horizontal and perpendicular to the direction in which the ventilation device drives the air to move. The first driving member is used to drive the rotating cylinder to rotate. During the rotation of the rotating drum relative to the housing, there are two extreme position states, which allow the inlet to communicate with the outlet or the return outlet.

[0009] By adopting the above technical solution, it is possible for staff to easily control the opening and closing status of the gas outlet and return outlet according to the heat dissipation and cooling methods required for the containerized gas generator set.

[0010] Optionally, the dust removal device includes two dust removal plates and two dust storage plates that correspond one-to-one, and both are disposed on the top of the second heat dissipation cavity; The dust removal plate is located above the corresponding dust storage plate, and one side of it contacts and abuts against the inner wall of the cavity; one side of the dust storage plate contacts and abuts against the inner wall of the cavity, and a dust storage space is directly formed between the dust storage plate and the inner wall of the cavity, and the dust storage space is located below the corresponding dust removal plate. When the rotating drum rotates to its limit position relative to the box, one side of the dust removal plate and one side of the dust storage plate, which are in the same set, are respectively close to the two sides of the opening.

[0011] By adopting the above technical solution, the filter screen installed at the inlet can be cleared of blockages during the use of the first control device, while reducing the probability that the cleared dust and other impurities will fall and affect the ventilation and refrigeration devices. This effectively extends the duration for which the filter screen installed at the inlet can intercept dust and other impurities, thereby effectively improving the reliability and stability of the filter screen installed at the inlet in intercepting dust and other impurities.

[0012] Optionally, two controllable openings are provided on one side of the housing, and the two openings communicate with the two dust storage spaces respectively when opened.

[0013] By adopting the above technical solution, it is convenient for staff to regularly clean dust and other impurities in the dust storage space, thereby effectively improving the reliability and stability of the dust removal plate and dust storage plate in removing and storing dust.

[0014] Optionally, it may also include a second control device for controlling the opening and closing of the air inlet; The second control device includes a sealing plate and a second drive component; The sealing plate is movably disposed on the housing and located in the first heat dissipation cavity, and the second driving member is used to drive the sealing plate to move; When the sealing plate moves to its limit position in the direction close to the air inlet, the air inlet is closed, and all of the heat dissipation vents are located on the side of the sealing plate away from the air inlet; when the sealing plate moves to its limit position in the direction away from the air inlet, the air inlet is opened, and the degree of communication between the side of the sealing plate near the air vent and the working chamber in the first heat dissipation cavity is less than the degree of communication between the side of the sealing plate near the air inlet and the working chamber.

[0015] By adopting the above technical solution, it is possible for staff to conveniently control the opening and closing of the air inlet according to the heat dissipation and cooling method required by the containerized gas generator set, and to effectively improve the air circulation effect after cooling, thereby further improving the heat dissipation and cooling effect and efficiency of the containerized gas generator set when the ambient temperature is higher than the generator operating temperature.

[0016] Optionally, the second control device further includes a base; The base is disc-shaped and is rotatably mounted on the bottom of the housing. The sealing plate is provided along one side edge of the base, and the second driving member is used to drive the base to rotate.

[0017] By adopting the above technical solution, it is possible for staff to easily control the movement of the sealing plate, while reducing the probability that the movement of the sealing plate will affect air circulation and the dust and other impurities trapped in the first heat dissipation cavity.

[0018] Optionally, the second control device may further include multiple partitions; Multiple partitions are disposed on the base and located on one side of the sealing plate, and the multiple partitions and the sealing plate together form a guide channel for guiding airflow.

[0019] By adopting the above technical solution, when the air inlet is open, more outside air can enter the working chamber through the heat dissipation port, thereby further improving the heat dissipation and cooling effect on the generator body at this time; when the air inlet is closed, the generator can fully dissipate heat during the internal air circulation heat dissipation process after cooling, and at the same time, the air circulation can drive away dust and other impurities above the base.

[0020] Optionally, the top of the partition contacts a plurality of the filters located at the heat dissipation vents, and the partition is used to remove dust from the filters during the rotation of the base.

[0021] By adopting the above technical solution, the filter screen installed at the heat dissipation vent can be cleared during the use of the control device, thereby effectively extending the time for the filter screen installed at the heat dissipation vent to intercept dust and other impurities, and thus effectively improving the reliability and stability of the filter screen installed at the heat dissipation vent in intercepting dust and other impurities.

[0022] Optionally, the housing has a dust collection space at the bottom of the second heat dissipation cavity and on the side opposite to the vent, and a dust discharge port that can be opened and closed and communicates with the dust collection space is provided on one side of the housing.

[0023] By adopting the above technical solution, dust and other impurities intercepted by the filter installed at the heat dissipation vent can be easily collected in the dust collection space under the drive of air circulation, making it convenient for staff to clean the dust and other impurities in the dust collection space regularly.

[0024] In summary, this application includes at least one of the following beneficial effects: 1. It allows staff to easily select appropriate heat dissipation and cooling methods based on the operating environment temperature of the containerized gas generator set, which can both meet the heat dissipation requirements for normal operation and effectively reduce the impact of dust and other impurities on the generator body. 2. During the operation of the first and second control devices by staff as needed, the filters at different locations can be cleared of blockages. The dust and other impurities obtained from the clearing process can be gathered, making it easier for staff to clean them regularly, thereby improving the reliability and stability of the filtration device in the long term.

Detailed Implementation

[0027] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0028] Reference Figure 1 and Figure 2 This application discloses a containerized gas generator set.

[0029] Reference Figure 2 and Figure 3 The containerized gas generator set includes a housing 1 serving as a protective shell, multiple generators 2 for gas power generation, a dust removal device 3 for intercepting dust and other impurities to prevent them from affecting the normal operation of the generators 2, a ventilation device 4 for driving air circulation to help the generators 2 dissipate heat, a refrigeration device 5 for cooling the air to improve the heat dissipation effect and efficiency of the generators 2, and a first control device 6 and a second control device 7 for allowing workers to adjust the heat dissipation method according to the working environment temperature.

[0030] The housing 1 has a rectangular parallelepiped structure, and its internal space is divided into a working chamber 11, a first heat dissipation chamber 12, and a second heat dissipation chamber 13. The working chamber 11 is rectangular parallelepiped in shape, and multiple generators 2 are evenly installed in the working chamber 11 at appropriate intervals and are concentrated near the bottom of the working chamber 11. The first heat dissipation chamber 12 is located below the working chamber 11, and its shape is also rectangular parallelepiped. Its length direction is parallel to the length direction of the working chamber 11, and its width direction is parallel to the width direction of the working chamber 11. The second heat dissipation chamber 13 is located on one side of the length direction of both the working chamber 11 and the first heat dissipation chamber 12. Its shape is also rectangular parallelepiped. Its length direction is parallel to the width direction of the working chamber 11, and its width direction is parallel to the length direction of the working chamber 11. A ventilation device 4 and a cooling device 5 are both installed in the second working chamber 11. The ventilation device 4 is used to drive the air in the second working chamber 11 to move upward along its height direction, and the cooling device 5 is installed below the ventilation device 4 and can cool the air passing around it. In this embodiment, the housing 1 preferably has a door for staff to enter and exit (details omitted in the accompanying drawings), and preferably multiple generators 2 are distributed in a rectangular array in the working chamber 11. Since the generators 2, ventilation devices 4 and refrigeration devices 5 with the above functions are all prior art in the field, they will not be described in detail here, and they are only briefly shown in the accompanying drawings.

[0031] Reference Figure 3 and Figure 4The housing 1 has several heat dissipation vents 15 between the working chamber 11 and the first heat dissipation chamber 12, which allow multiple generators 2 to dissipate heat directly downwards and allow air circulation. The working chamber 11 and the first heat dissipation chamber 12 are connected through the heat dissipation vents 15. The housing 1 has an air inlet 14 on the side of the first heat dissipation chamber 12 away from the second heat dissipation chamber 13, which allows outside air to enter the housing 1. The first heat dissipation chamber 12 is connected to the outer space at the bottom of the housing 1 through the air inlet 14. The housing 1 has a vent 16 on the bottom of the second heat dissipation chamber 13 near the first heat dissipation chamber 12, which is connected to the first heat dissipation chamber 12 through the vent 16. The housing 1 has an air outlet 17 and a return outlet 18 on both sides of the top of the second heat dissipation chamber 13. The second heat dissipation chamber 13 is connected to the outer space at the top of the housing 1 through the air outlet 17, and the second heat dissipation chamber 13 is connected to the top of the working chamber 11 through the return outlet 18.

[0032] Reference Figure 1 and Figure 3 The first control device 6 is installed on the top of the housing 1 near the second heat dissipation cavity 13. It is used to control the opening and closing state of the air outlet 17 and the return port 18, so that the opening and closing states of the air outlet 17 and the return port 18 are reversed (that is, when the air outlet 17 is open, the return port 18 is closed, and vice versa).

[0033] The first control device 6 includes a rotating drum 61 rotatably installed inside the housing 1 and a first driving member 62 for driving the rotating drum 61 to rotate.

[0034] The rotating cylinder 61 is a hollow cylindrical structure with a cylindrical cavity 611 inside, the axis of which coincides with the axis of the rotating cylinder 61. The rotating cylinder 61 is located at the top of the second heat dissipation cavity 13, one end of which is rotatably connected to the housing 1 along its axial direction, and its rotation axis coincides with its own axis. The cavity 611 extends through the other end of the rotating cylinder 61 along its axial direction to form an opening, and two openings are formed radially through the outer side of the rotating cylinder 61 to allow the second heat dissipation cavity 13 to communicate with the cavity 611. The rotating cylinder 61 has a through-hole 612 between the two openings, which communicates with the cavity 611. In this embodiment, preferably, the opening direction of the through-hole 612 is perpendicular to the through-hole direction.

[0035] The first driving component 62 is fixedly installed on one side of the housing 1 in the width direction, and is used to drive the rotating drum 61 to rotate relative to the housing 1. In this embodiment, the first driving component 62 is preferably a servo motor; since servo motors are common prior art, they will not be described in detail here, and are only briefly shown in the accompanying drawings.

[0036] The first driving member 62 restricts the rotation of the rotating drum 61 relative to the housing 1, meaning the rotating drum 61 has two extreme position states during rotation. One state is where the cavity 611 communicates with the second heat dissipation cavity 13 through an opening on one side of the rotating drum 61 and with the air outlet 17 through a port 612. The other state is where the cavity 611 communicates with the second heat dissipation cavity 13 through an opening on the other side of the rotating drum 61 and with the return port 18 through a port 612. In this embodiment, it is preferable that the port 612, the air outlet 17, and the return port 18 are of the same size, meaning that when the rotating drum 61 rotates to its extreme position, there is always one port 612 that is fully connected to either the air outlet 17 or the return port 18. Furthermore, it is preferable that the first driving member 62 drives the rotating drum 61 to rotate within a range of 180° relative to the housing 1.

[0037] The dust removal device 3 includes multiple filters 31 for intercepting dust and other impurities, and the multiple filters 31 are respectively fixedly installed at the air inlet 14, several heat dissipation vents 15, air outlet 17, return port 18, and through port 612. In this embodiment, the filtration effect of the filters 31 installed at the air inlet 14 and air outlet 17 is preferably lower than that of the filters 31 installed at the heat dissipation vents 15, return port 18, and through port 612; since the filters 31 with the above functions are common prior art, they will not be described in detail here, and only a brief representation is given in the accompanying drawings.

[0038] Reference Figure 2 and Figure 3 The dust removal device 3 also includes two dust removal plates 32 and two dust storage plates 33 for removing and storing dust from the filter screen 31 installed at the inlet 612 to achieve the effect of clearing blockage, and the two dust removal plates 32 and the two dust storage plates 33 correspond one-to-one.

[0039] The dust removal plate 32 has a rectangular plate structure. One end of its length is fixedly connected to the inner wall of the top of the second heat dissipation cavity 13 away from the first driving member 62, and its length is parallel to the width direction of the housing 1. The dust removal plate 32 is located in the cavity 611. One side of its width direction contacts and abuts against the inner wall of the cavity 611 and is used to scrape off dust and other impurities from the surface of the filter screen 31 installed at the opening 612. During the rotation of the rotating drum 61 relative to the housing 1, one side of the dust removal plate 32 in the width direction will remain in contact with and abut against the inner wall of the cavity 611.

[0040] The dust collection plate 33 has a rectangular folded plate structure. One end of its length is also fixedly connected to the inner wall of the top of the second heat dissipation cavity 13 away from the first driving member 62, and its length is parallel to the width direction of the box 1. The dust collection plate 33 is located in the cavity 611 and below the corresponding dust removal plate 32. One side of its width direction contacts and abuts against the inner wall of the cavity 611 and also has the effect of scraping off dust and other impurities from the surface of the filter screen 31 installed at the opening 612. A dust collection space 8 is formed between it and the inner wall of the cavity 611 for the dust and other impurities scraped off by the corresponding dust removal plate 32 to accumulate. During the rotation of the rotating drum 61 relative to the box 1, one side of the dust collection plate 33 in the width direction will remain in contact with and abut against the inner wall of the cavity 611. In this embodiment, the dust removal plates 32 and dust storage plates 33 are preferably aligned vertically, and the dust removal plates 32 are inclined. The two dust removal plates 32 are vertically upward and flared, so that the dust and other impurities scraped off by them fall into the dust storage space 8 below under the action of gravity. It is also preferred that when the rotating drum 61 is rotated to the limit position, there is always one side of a set of dust removal plates 32 and one side of the dust storage plate 33 close to the two sides of the opening 612 respectively.

[0041] Furthermore, to facilitate regular cleaning of dust and other impurities accumulated in the dust storage space 8 by staff, it is preferable that the housing 1 has two clearance openings 131 on the side opposite to the first driving member 62, each communicating with one of the two dust storage spaces 8. This allows staff to use tools to reach into the dust storage space 8 and drive dust and other impurities out through the clearance openings 131. Two covers 19 are movably installed on the outside of the housing 1 to control the opening and closing of the two clearance openings 131. In this embodiment, it is preferable that the covers 19 are rotatably connected to the housing 1 and can be locked in position relative to the housing 1. Since the covers 19 with the above functions are common prior art, they will not be described in detail here, and are only briefly shown in the accompanying drawings.

[0042] Reference Figure 5 and Figure 6 The second control device 7 is installed at the bottom of the housing 1 near the first heat dissipation cavity 12. It is used to control the opening and closing state of the air inlet 14, and it works in conjunction with the first control device 6 to change the heat dissipation method of the containerized gas generator set.

[0043] The second control device 7 includes a base 71, a second drive component 72, a sealing plate 73, and multiple partitions 74.

[0044] The base 71 is generally disc-shaped and is rotatably mounted on the bottom of the housing 1 and located at the bottom of the first heat dissipation cavity 12. Its top end face is flush with the inner wall of the bottom of the first heat dissipation cavity 12. The rotation axis of the base 71 coincides with its own axis and is parallel to the height direction of the housing 1.

[0045] The second drive component 72 is fixedly installed at the bottom of the housing 1 and located below the first heat dissipation cavity 12, and is used to drive the base 71 to rotate relative to the housing 1. In this embodiment, the second drive component 72 is preferably a servo motor; and preferably, the bottom of the housing 1 has a raised structure, so that a space is formed below the housing 1 for the installation of the second drive component 72.

[0046] The sealing plate 73 has an overall arc-shaped plate structure. It is fixedly installed above the base 71 and extends along the circumference of the base 71. During the rotation of the base 71 relative to the housing 1, the top of the sealing plate 73 remains in contact with the inner wall of the top of the first heat dissipation cavity 12.

[0047] Multiple partitions 74 are fixedly installed above the base 71 and located on one side of the sealing plate 73. The width direction of the partitions 74 is parallel to the axial direction of the base 71, and the partitions 74 and the sealing plate 73 are spaced apart from each other, forming a guide channel 75 for guiding air to flow along a certain trajectory. During the rotation of the base 71 relative to the housing 1, the top of the partitions 74 remains in contact with the inner wall of the top of the first heat dissipation cavity 12 and has the effect of scraping away dust and other impurities intercepted by the filters 31 installed at the heat dissipation vents 15. In this embodiment, the partitions 74 are preferably arc-shaped plates, and preferably the area swept by the multiple partitions 74 after rotating one revolution with the base 71 is equal to the area of ​​the top surface of the base 71.

[0048] Reference Figure 3 and Figure 5 The second driving component 72 restricts the rotation of the base 71 relative to the housing 1. When the base 71 rotates and moves the sealing plate 73 to its limit position towards the air inlet 14, the sealing plate 73 forms an interception in the first heat dissipation cavity 12, preventing air from the outer space of the housing 1 from entering the first heat dissipation cavity 12 through the air inlet 14 and then entering the working cavity 11 through the heat dissipation vent 15 (i.e., the air inlet 14 is closed). At this time, the working cavity 11 will be connected to the guide channel 75 and the air in the first heat dissipation cavity 12 located on the side of the sealing plate 73 away from the air inlet 14 through several heat dissipation vents 15. The air in the first heat dissipation chamber 12 is connected to the air inlet 14. When the base 71 rotates, it causes the sealing plate 73 to move away from the air inlet 14 to its limit position. At this time, the sealing plate 73 also forms an interception in the first heat dissipation chamber 12, so that the air entering the first heat dissipation chamber 12 through the air inlet 14 will pass through the guide channel 75 and then through part of the heat dissipation vents 15 (more heat dissipation vents 15) into the working chamber 11. The cavity 611 in the working chamber 11 will return to the first heat dissipation chamber 12 through part of the heat dissipation vents 15 (less heat dissipation vents 15) and then enter the second heat dissipation chamber 13 through the vent 16 (i.e., the air inlet 14 is open). In this embodiment, it is preferable that the second driving member 72 drives the base 71 to rotate relative to the housing 1 at an angle range of 180°. Reference Figure 2 and Figure 3 Furthermore, in order to facilitate the accumulation of dust and other impurities at the bottom of the first heat dissipation cavity 12 and the second heat dissipation cavity 13, and to reduce the probability of them coming into contact with the ventilation device 4 and the cooling device 5 with the airflow, it is preferable that the bottom of the housing 1 has a dust collection space 9 for the accumulation of dust and other impurities at the position of the second heat dissipation cavity 13 away from the first heat dissipation cavity 12; the dust collection space 9 is connected to the bottom of the second heat dissipation cavity 13, and the inner wall of the bottom of the dust collection space 9 is flush with the inner wall of the bottom of the second heat dissipation cavity 13, the inner wall of the bottom of the vent 16 and the inner wall of the bottom of the first heat dissipation cavity 12.

[0049] Furthermore, to facilitate regular cleaning of dust and other impurities accumulated in the dust collection space 9 by staff, it is preferable that the housing 1 has a dust discharge port 132 communicating with the dust collection space 9 on the side opposite to the first driving member 62. This allows staff to use tools to reach into the dust collection space 9 and drive dust and other impurities out through the dust discharge port 132. A cover plate 19 for controlling the opening and closing of the dust discharge port 132 is also movably installed on the outside of the housing 1. In this embodiment, it is also preferable that the cover plate 19 is rotatably connected to the housing 1 and can be locked in position relative to the housing 1.

[0050] The implementation principle of a containerized gas generator set in this application embodiment is as follows: When the ambient temperature of the containerized gas generator set is low, i.e., the temperature of the outside air is sufficient to cool the generator 2, the first control device 6 and the second control device 7 are operated first to open the air inlet 14 and connect the outlet 612 to the outlet 17. Then, the ventilation device 4 is activated, and the cooling device 5 is in standby mode. At this time, outside air at the bottom of the container 1 enters the first heat dissipation chamber 12 through the air inlet 14, then enters the working chamber 11 through the guide channel 75 and several heat dissipation outlets 15, then returns to the first heat dissipation chamber 12 through several heat dissipation outlets 15, then enters the second heat dissipation chamber 13 through the vent 16, then enters the cavity 611 through the vent 612, and finally exits into the container through the vent 612 and the outlet 17. In the external space at the top of body 1; during this process, the heat emitted by the operation of multiple generators 2 can be carried by the surrounding air and actively enter the first heat dissipation chamber 12, while the air circulation can actively bring the cooler air into the working chamber 11 and drive the warmer air out of the housing 1, and the position of the exhaust box 1 is at a certain height, so it has little impact on the surrounding staff; in addition, dust and other impurities will be mainly intercepted on the outer surface of the filter 31 installed at the air inlet 14 and the lower surface of the filter 31 installed at the heat dissipation port 15. The dust and other impurities intercepted on the outer surface of the filter 31 installed at the air inlet 14 are easy for staff to clean directly, while the dust and other impurities intercepted on the lower surface of the filter 31 installed at the heat dissipation port 15 will accumulate in the guide channel 75; When the ambient temperature of the containerized gas generator set is high, meaning the outside air temperature is insufficient to cool the generator 2, the first control device 6 and the second control device 7 are operated first to close the air inlet 14 and connect the outlet 612 to the return outlet 18. Then, the ventilation device 4 and the cooling device 5 are started simultaneously. At this time, outside air cannot enter the container 1 through the air inlet 14 or the outlet 17, and the air inside the container 1 will form an internal circulation. The heat emitted by the multiple generators 2 is carried by the surrounding air and will be driven through several heat dissipation outlets 15 into the first heat dissipation chamber 12, then through the vent 16 into the second heat dissipation chamber 13. After being cooled by the cooling device 5, it enters the cavity 611 through the outlet 612, and finally returns to the working chamber 11 through the outlet 612 and the return outlet 18, where the cooled air assists in cooling the multiple generators 2. During the process, the amount of dust and other impurities inside the housing 1 will not increase compared to before. The dust and other impurities previously accumulated in the guide channel 75 will be carried by the airflow, first entering the bottom of the second heat dissipation cavity 13 through the vent 16, and then accumulating in the dust collection space 9. If some dust and other impurities continue to move upward into the cavity 611 with the airflow in the second heat dissipation cavity 13, they will be intercepted by the filter screen 31 installed at the opening 612 (dust and other impurities may be intercepted on both sides). Among them, the dust and other impurities on the inner surface of the filter screen 31 will be scraped off by the dust removal plate 32 or the dust storage plate 33 during the rotation of the drum 61, and the dust and other impurities will fall into the dust collection space 8 for collection and subsequent cleaning by the staff. The dust and other impurities on the outer surface of the filter screen 31 will be scraped off by the internal structure of the housing 1 during the rotation of the drum 61, fall back to the bottom of the second heat dissipation cavity 13, and be collected in the dust collection space 9.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
